Preface

Wittgenstein once said that a whole philosophy book could be written consisting of nothing but jokes. This is not that book, nor does this book treat the history of philosophy as a joke. This book takes philos- ophy seriously, but not gravely. As the subtitle indicates, the goal of the book is to lighten the load a bit. How to do this without simply throwing the cargo overboard? First, by presenting an overview of Western philosophy from the sixth century B.C.E. through most of the twentieth century in a way that introduces the central philosophical ideas of the West and their evolution in a concise, readable format without trivializing them, but at the same time, without pretending to have exhausted them nor to have plumbed their depths. Second, following a time-honored medieval tradition, by illuminating the mar- gins of the text. Some of these illuminations, namely those that attempt to schematize difficult ideas, I hope will be literally illuminat- ing. Most of them, however, are simply attempts in a lighter vein to interrupt the natural propensity of the philosophers to succumb to the pull of gravity. (Nietzsche said that only the grave lay in that direction.) But even these philosophical jokes, I hope, have a pedagog- ical function. They should serve to help the reader retain the ideas that are thereby gently mocked. Thirty years of teaching the subject, which I love—and which has provoked more than a few laughs on the part of my students—convinces me that this technique should work.

iii

I do not claim to have achieved Nietzsche’s “joyful wisdom,” but I agree with him that there is such a thing and that we should strive for it.

Before turning you over to Thales and his metaphysical water (the first truly heavy water), I want to say a word about the women and their absence. Why are there so few women in a book of this nature? There are a number of possible explanations, including these:

1. Women really are deficient in the capacity for sublimation and hence are incapable of participating in higher culture (as Schopenhauer and Freud suggested).

2. Women have in fact contributed greatly to the history of philosophy, but their contributions have been denied or sup- pressed by the chauvinistic male writers of the histories of philosophy.

3. Women have been (intentionally or unintentionally) system- atically eliminated from the history of philosophy by political, social, religious, and psychological manipulations of power by a deeply entrenched, jealous, and fearful patriarchy.

I am certain that the first thesis does not merit our serious attention. I think there is some truth to the second thesis, and I may be partially guilty of suppressing that truth. For example, the names of at least seventy women philosophers in the late classical period alone have been recorded, foremost of which are Aspasia, Diotima, Aretê, and Hypatia. (Hypatia has been belatedly honored by having a journal of feminist philosophy named after her.) Jumping over cen- turies to our own age, we find a number of well-known women con- tributing to the history of philosophy in the first half of the twentieth century, including Simone de Beauvoir, Susanne Langer, and L. Susan Stebbing.

However, no matter how original, deep, and thought-provoking were the ideas of these philosophers, I believe that, for a number of reasons (those reasons given in the second and third theses are probably most pertinent here), none of them has been as historically significant as the ideas of those philosophers who are discussed in this book. Fortunately, things have begun to change in the past few

years. An adequate account of contemporary philosophy could not in good faith ignore the major contributions to the analytic tradition of philosophers Iris Murdoch, Philippa Foot, G. E. M. Anscombe, and Judith Jarvis Thompson, nor those contributions to the Continental tradition made by Gayatri Chakravorty Spivak, Monique Wittig, Luce Irigaray, and Julia Kristeva. Furthermore, a new wave of women phi- losophers is already beginning to have considerable impact on the content of contemporary philosophy and not merely on its style.

So, despite the risks, I defend the third thesis. I truly believe that if women had not been systematically excluded from major par- ticipation in the history of philosophy,1 that history would be even richer, deeper, more compassionate, and more interesting (not to mention more joyful) than it already is. It is not for nothing that the book ends with a discussion of the work of a contemporary woman philosopher and with a question posed to philosophy herself, “Quo vadis?”—Whither goest thou?

The fourth edition proceeds with the refinement of presentation begun in the second edition and with the addition of new material ini- tiated in the third edition. I have had some help with all four editions of this book. For suggestions with the earlier editions, I am grateful to Timothy R. Allan, Trocaire College; Dasiea Cavers-Huff, Riverside Community College; Job Clement, Daytona Beach Community College; Will Griffis, Maui Community College; Julianna Scott Fein, Mayfield Publishing Company; Hans Hansen, Wayne State University; Fred E.

For excellent suggestions concerning this fourth edition I thank Robert Caputi, Trocaire College; Janine Jones, University of North Carolina, Greensboro; Amber L.

My editorial coordinator, Allison Rona, has been exceptionally helpful. Also at McGraw-Hill I am indebted to Leslie LaDow, the production editor, and copyeditor Karen Dorman. My wife, Leila May, has been my most acute critic and my greatest source of inspiration. She kept me laughing during the dreariest stages of the production of the manuscript, often finding on its pages jokes that weren’t meant to be there. I hope she managed to catch most of them. There probably are still a few pages that are funnier than I intended them to be.

The story of Western philosophy begins in Greece.

Introduction

The Greek word “Logos” is the source of the English word “logic” as well as all the “logies” in terms like “biology,” “sociology,” and “psy- chology,” where “logos” means the theory, or study, or rationalization of something. “Logos” also means “word” in Greek, so it involves the act of speaking, or setting forth an idea in a clear manner. “Logos,” therefore, designates a certain kind of thinking about the world, a kind of logical analysis that places things in the context of reason and explains them with the pure force of thought. Such an intellec- tual exercise was supposed to lead to wisdom (Sophia), and those who dedicated themselves to Logos were thought of as lovers of wis- dom (love = philo), hence as philosophers.

What was there before philosophy, before Logos? There was Mythos—a certain way of thinking that placed the world in the con- text of its supernatural origins. Mythos explained worldly things by tracing them to exceptional, sometimes sacred, events that caused the world to be as it is now. In the case of the Greeks, Mythos meant

tracing worldly things to the dra- matic acts of the gods of

Mount Olympus. The narra- tives describing these ori-

gins—myths—are not only explanatory but also morally exemplary and ritualistically instruc- tive; that is, they pro- vide the rules that, if followed by all, would create the foundation of a genuine community of togetherness— a “we” and an “us” instead of a mere con- glomeration of individu- als who could only say

Explaining Ancient Greek Customs

“I” and “me.” Hence, myths are often conservative in nature. They seek to maintain the status quo by replicating origins: “So behaved the sacred ancestors, so must we behave.” Myths had the advantage of creating a whole social world in which all acts had meaning. They had the disadvantage of creating static societies, of resisting innovation, and, many would say, of being false. Then, suddenly, philosophy hap- pened—Logos broke upon the scene, at least according to the tradi- tional account. (There are other accounts, however, accounts that suggest that Western Logos—philosophy and science—is just our version of myth.) But let us suppose that something different did take place in Greece about 700 B.C.E.1 Let’s suppose that the “first” philosopher’s explanation of the flooding of the Nile River during the summer (most rivers tend to dry up in the summer) as being caused by desert winds (desert winds, not battles or love affairs among gods) really does constitute novelty. Natural phenomena are ex- plained by other natural phenomena, not by supernatural events in “dream time”—the time of the ancient gods. In that case, Greece truly is the cradle of Western philosophy.

Why Greece, and not, for example, Egypt or Judea? Well, let’s be honest here. Nobody knows. Still, a number of histori- cal facts are rele- vant to the explana- tion we seek. For one, there was a very productive contact between ancient Greece and the cultures of the east- ern Mediterranean region—Persia,

Once, many many years ago, there was a big bang. But great fathers Galileo and Newton were not dismayed. They conferred and said, “It is good.”

A Modern Myth?

Mesopotamia, Phoenicia, Cyprus, southern Italy, and Egypt, among others. The Greeks were a well-traveled group and were extremely adept at borrowing ideas, conventions, and artistic forms from the cultures they encountered and applying these elements creatively to their own needs. There is also a controversial theory that Greek cul- ture derives greatly from African sources.2 It is at least certain, as one historian of Greek ideas has recently said, that “the cultural achievements of archaic and classical Greece are unthinkable without Near Eastern resources to draw upon,”3 and eastern North Africa fits into this map.

Also, unlike the case in some of the surrounding societies, there was no priestly class of censors in Greece. This observation does not mean that Greek thinkers had no restrictions on what they could say—we will see that several charges of impiety were brought against

4 ◆ Introduction

some of them in the period under study—but that they were able nevertheless to get away with quite a bit that went against prevailing religious opinion.

Another historical fact is that the Greek imagination had always been fertile in its concern with intimate detail. For example, Homer’s description of Achilles’ shield takes up four pages of the Iliad. In addition, the many generations of Greek children who grew up on the poems of Homer and Hesiod4—two of the main vehicles that transmitted Greek religion—recognized in them their argumentative, intellectually combative, and questioning nature. The polemical nature of Greek drama and poetry would find a new home in Greek philosophy.

A final component of the world into which philosophy was born is the socioeconomic structure that produced a whole leisured class of

Introduction ◆ 5

people—mostly male people—with time on their hands that they could spend meditating on philosophical issues. It is always jolting to remember that during much of Greece’s history, a major part of the economic foundation of its society was slave labor and booty from military conquests. This fact takes some of the luster from “the Glory that was Greece.”

Still, for whatever reasons, the poetry and drama of the Greeks demonstrate an intense awareness of change, of the war of the opposites—summer to winter, hot to cold, light to dark, and that most dramatic change of all, life to death.

Indeed, this sensitivity to the transitory nature of all things sometimes led the Greeks to pessimism. The poets Homer, Mimner- mus, and Simonides all expressed the idea “Generations of men fall like the leaves of the forest.”5

6 ◆ Introduction

But this sensitivity also led the Greeks to demand an explanation— one that would be obtained and justified not by the authority of reli- gious tradition but by the sheer power of human reason. Here we find an optimism behind the pessimism—the human mind operating on its own devices is able to discover ultimate truths about reality.

But let us not overemphasize the radicalness of the break made by the Greek philosophers with the earlier, mythical ways of thinking. It’s not as if suddenly a bold new atheism emerged, reject- ing all religious explanations or constraints. In fact, atheism as we understand it today was virtually unknown in the ancient world.6

Rather, these early Greek philosophers reframed the perennial puzzles about reality in such a way as to emphasize the workings of nature rather than the work of the gods. For instance, they tended to demote cosmogony (theories about the origins of the world) and promote cosmology (theories about the nature of the world).

This new direction represents the beginnings of a way of thinking that the Greeks would soon call “philosophy”—the love of wisdom. We

Introduction ◆ 7

can discern in these early efforts what we now take to be the main fields of the discipline that we too call philosophy: ontology (theory of being); epistemology (theory of knowledge); axiology (theory of value), which includes ethics, or moral philosophy (theory of right behavior), and aesthetics (theory of beauty, or theory of art); and logic (theory of correct inference).

In fact, the theories put forth in ancient Greece could be called the origins of Western science with as much justification as they can be called the origins of Western philosophy, even though at that early period no such distinctions could be made. Roughly, I would say that science deals with problems that can be addressed experimentally by subsuming the observable events that puzzle us under the dominion of natural laws and by showing how these laws are related causally to those events. Philosophy, on the other hand, deals with problems that require a speculative rather than an experimental approach. Such problems often require conceptual analysis (the logical scrutiny of general ideas) rather than observation or data gathering. Consider these questions, paying special attention to the italicized words:

Can we know why on rare occasions the sun darkens at midday? Is it true that the moon’s passing between the earth and the

sun causes such events? Can there be successful experiments that explain this

phenomenon?

These questions are scientific questions. Now compare these ques- tions to the following ones, paying attention again to the words in italics:

What is knowledge? What is truth? What is causality? What is value? What is explanation?

These questions invite conceptual analysis, which is part of philosophy. But we are moving too fast and looking too far ahead. As I said,

such distinctions had not yet been clearly drawn in the ancient world.

8 ◆ Introduction

The thinkers there were satisfied to have asked the kinds of ques- tions that were foundational both to philosophy and to science.

Topics for Consideration

1. Pick some observable phenomenon, such as what we now call the eclipse of the sun, and explain it from the perspective of science, and then again from some system of myth. (You may have to visit the library for this exercise.) Then use these two “stories” to demonstrate the difference between Logos and Mythos.

2. Think about your own patterns of belief. Are there any of them that you would acknowledge as Mythos rather than Logos? Here are two exam- ples: (A) If you have religious beliefs, how would you characterize them in terms of this distinction? (B) What would it mean to assert that science itself is simply an instance of Western Mythos?

Notes

1. I have chosen to use the new dating coordinates B.C.E. (Before the Common Era) and C.E. (Common Era) rather than the older B.C. (Before Christ) and A.D. (Anno Domini, or The Year of Our Lord) because the attempt to gauge the whole of human history from the perspective of a particular religious tradition no longer seems tenable. But let’s face it: This new system is a bit artificial. Probably there is some- thing arbitrary about all attempts to date historical events. At least I am not fol- lowing the lead of the nineteenth-century philosopher Friedrich Nietzsche, who pro- claimed, “History begins with my birth.” (We’ll study Nietzsche later.)

Notes ◆ 9

The thinkers who were active in Greece between the end of the seventh century B.C.E. and the middle of the fourth century B.C.E. are known today as the pre-Socratic philosophers, even though the last of the group so designated were actually contemporaries of Socrates.

10

1 The Pre-Socratic

Philosophers Sixth and Fifth Centuries B.C.E.

(Socrates was born in 469 and died in 399 B.C.E. We look at his thought in the next chapter.) What all the pre-Socratic philosophers have in common is their attempt to create general theories of the cosmos (kosmos is the Greek term for “world”) not simply by repeat- ing the tales of how the gods had created everything, but by using observation and reason to construct general theories that would explain to the unprejudiced and curious mind the secrets behind the appearances in the world. Another commonality was that all the pre- Socratic philosophers stemmed from the outlying borders of the Greek world: islands in the Ionian Sea or Greek colonies in Italy or along the coast of Persia (in today’s Turkey). Knowledge of these thinkers is tremendously important not only for understanding the Greek world of their time, but—as I have argued in the Introduc- tion—for grasping the origins of Western philosophy and science.

The problem is that in fact very little is known about the pre- Socratic philosophers. Most of the books that they wrote had already disappeared by the time that the philosopher Aristotle (384–322 B.C.E.) tried to catalog and criticize their views. Today’s understanding of the pre-Socratics is based mostly on summaries of their ideas by Aristotle and by later Greek writers who had heard of their views only by word of mouth. Many of these accounts are surely inaccurate because of distortions caused by repetition over several generations by numerous individuals. (Have you ever played the game called Telephone, in which a complicated message is whis- pered to a player, who then whispers it to the next player, and so on, until the message—or what’s left of it—is announced to the whole group by the last player in the circle?) Also, these summaries often contained anachronistic ideas, that is, ideas from the later time projected back into the earlier views. Only fragments of the original works remain in most cases today, and even those few existing passages do not always agree with one another. Remember, these “books” were all written by hand on papyrus (a fragile early paper made from the crushed and dried pulp of an Egyptian water plant), and all editions of these books were copied manually by

The Pre-Socratic Philosophers ◆ 11

professional scribes. Furthermore, the meaning of many of the frag- ments is debatable, both because of the “fragmentary” nature of the scraps—key words are missing or illegible—and because of the obscure language in which many of these works were written. Never- theless, a tradition concerning the meaning of the pre-Socratics had already developed by Aristotle’s time, and it is that version of their story that influenced later philosophers and scientists. Aristotle is not the only source of our information about the pre- Socratics, but unfortunately most of the additional information comes from post-Aristotelian commentators giving interpretations of Aristotle’s remarks. We do not know to what extent the material provided by these other sources is informed by extraneous sources. So Aristotle appears to be our real source, and we have no clear idea of his accuracy because he paraphrases the various pre- Socratics.1 Therefore, the tradition that I report here is flawed and distorted in many ways.

Thales

Philosophy makes its first self-presentation in three consecutive gen- erations of thinkers from the little colony of Miletus on the coast of Asia Minor—today’s Turkey—in the sixth century B.C.E. The first recorded philosopher is Thales of Miletus (ca. 580 B.C.E.). Apparently, he did not write a book, or if he did, it is long lost.

If we can trust Aristotle and his commentators, Thales’ argu- ment was something like this:

If there is change, there must be some thing that changes, yet does not change. There must be a unity behind the apparent plurality

Thales ◆ 13

What substance must underlie grass to allow it to be transformed to milk?

GRASS TO MILK

of things, a Oneness disguised by the superficial plurality of the world. Otherwise the world would not be a world; rather, it would be a disjointed grouping of unrelated fragments.

So what is the nature of this unifying, ultimately unchanging substance that is disguised from us by the appearance of constant change?

Like the myth makers before him, Thales was familiar with the four elements: air, fire, water, and earth. He assumed that all things must ultimately be reducible to one of these four—but which one?

Of all the elements, water is the most obvious in its transfor- mations: Rivers turn into deltas, water turns into ice and then back

14 ◆ Chapter 1 The Pre-Socratic Philosophers

into water, which in turn can be changed into steam, which becomes air, and air, in the form of wind, fans fire.

Then water it is! All things are composed of water.

Thales’ actual words were: “The first principle and basic nature of all things is water.”2

This obviously false conclusion is valued today not for its con- tent but for its form (it is not a great leap between the claim “All things are composed of water” and the claim “All things are com- posed of atoms”) and for the presupposition behind it (that there is an ultimate stuff behind appearances that explains change while remaining itself unchanged). Viewed this way, Thales can be seen as the first philosopher to introduce the project of reductionism. Reductionism is a method of explanation that takes an object that confronts us on the surface as being one kind of thing and shows that the object can be reduced to a more basic kind of thing at a deeper but less obvious level of analysis. This project is usually seen as a major function of modern science.

Thales ◆ 15

I regret to say that I must add three other ideas that Aristotle also attributes to Thales. My regret is due to the capacity of these ideas to undercut what has seemed so far to be a pretty neat foun- dation for future science. Aristotle says that, according to Thales,

(A) The earth floats on water the way a log floats on a pond. (B) All things are full of gods. (C) A magnet (loadstone) must have a soul, because it is able

to produce motion.

The first of these ideas, (A), is puzzling because it seems gratuitous. If everything is water, then it is odd to say that some water floats on water. (B) shows us that the cut between Mythos and Logos is not as neat in Thales’ case as I have appeared to indicate. (C) seems somehow related to (B), but in conflicting ways. If according to (B) all things are full of gods, then why are the magnets mentioned in (C) any different from everything else in nature? No surprise that over the years scholars have spilled a lot of ink—and, because the debate still goes on, punched a lot of computer keys—trying to make sense of these ideas that Aristotle attributes to Thales.

Anaximander

Several generations of Thales’ followers agreed with his key insight— that the plurality of kinds of things in the world must be reducible to one category—but none of them seems to have accepted his formula

16 ◆ Chapter 1 The Pre-Socratic Philosophers

that everything is water. His student Anaximander (ca. 610–ca. 546 B.C.E.), also from the city of Miletus, said that if all things were water, then long ago everything would have returned to water. Anaximander asked how water could become its deadly enemy, fire—how a quality could give rise to its opposite. That is, if observable objects were really just water in various states of agitation—as are ice and steam— then eventually all things would have settled back into their primor- dial liquid state. Aristotle paraphrases him this way: If ultimate real- ity “were something specific like water, the other elements would be annihilated by it. For the different elements have contrariety with one another. . . . If one of them were unlimited the others would have ceased to exist by now.”3 (Notice that if this view can be accurately attributed to Anaximander, then he subscribed to an early view of the principle of entropy, according to which all things have a tendency to seek a state of equilibrium.)

For Anaximander, the ultimate stuff behind the four elements could not itself be one of the elements. It would have to be an un- observable, unspecific, indeterminate something-or-other, which he called the Boundless, or the Unlimited (apeiron in Greek). It would

Anaximander ◆ 17

have to be boundless, unlimited, and unspecific because anything specific is opposed to all the other specific things in existence. (Water is not fire, which in turn is not air, and air is not earth [not dirt and rock].) Yet the Boundless is opposed to nothing, because every- thing is it.

Anaximander seems to have imagined the Boundless as originally moving effort- lessly in a great cosmic vortex that was interrupted by some disaster (a Big Bang?), and that disaster caused oppo- sites—dry and wet, cold and

hot—to separate off from the vortex and to appear to us not only as qualities but as the four basic elements: earth, water, air, and fire.

Anaximander wrote a book in prose, one of the first such books ever written. But papyrus does not last forever, and only one passage remains that we can be fairly certain comes from his book. However, that passage is a zinger.

And from what source things arise, to that they return of necessity when they are destroyed, for they suffer punishment and make repara- tion to one another for their injustice according to the order of time.4

There are many possible interpretations of this amazing state- ment. According to the most dramatic interpretation, the whole

18 ◆ Chapter 1 The Pre-Socratic Philosophers

world as you and I know it is the result of a cosmic error. Creation is an act of injustice. But justice will be done; the world will eventually be destroyed, and “things” will return to their boundless source and revolve eternally in a vortex. This interpretation, which contains at least as much Mythos as Logos, exhibits a bizarre kind of optimism about the triumph of justice.

A less radical, less mythical, and more likely interpretation would be this: Once the four elements were created, they became related to one another in antagonistic ways, but their opposition to one another balances out in an ecological harmony. If one element dominates at one period (say, water in a time of flood), it will later be compensated by the domination of another element at another period (say, fire in a drought). So the original unity of the Boundless is preserved in the apparent war of the opposites.

A very important part of this passage is the claim that the events described occur “of necessity . . . according to the order of

time.” This process, then, is not due to the whims of the gods, and the “punishment” and “reparation” for the “injustice” is not reprisal against individual humans by angry divinities. Natural laws are govern- ing these processes with inevitability. If the working out of these laws is described by Anaximander in the moral and legal language of the old myths, his description simply shows, as the eminent pre-Socratic scholar Malcolm Schofield says, “that Anaximander is a revolutionary who carries some old-fashion baggage with him. That is the general way with revolutions.”5 In any case, the cause of these processes— the apeiron—is immortal and indestructible, qualities usually associ- ated with gods, as Aristotle points out.6 Again, we see that pre- Socratic philosophy has not completely divorced itself from its religious origins.

Other striking ideas have been attributed to Anaximander: (1) Because the same processes that are at work here are at work everywhere, there is a plurality of universes. (2) The earth needs no support (remember Thales’ “floating like a log in water”). Because the earth is right smack in the middle of the universe (well, our universe), it is “equidistant from all things.” (3) The four elements concentrate in certain regions—in concentric circles—of the cosmos, with earth (the heaviest) in the center, surrounded by a circle of water, then another of air, then one of fire. A wheel of fire circles our slower earth. What we see as the stars are really holes in the outer ring, or “tube- like vents,” with fire showing through.

This last cosmological picture painted by Anaximander had an amazingly long life. Merrill Ring quotes the sixteenth-century British poet Edmund Spenser as writing:

The earth the air the water and the fire Then gan to range themselves in huge array, and with contrary forces to conspire Each against other by all means they may.7

And in the early seventeenth century, Miguel de Cervantes relates a heroic adventure of Don Quixote and Sancho in which a group of bored aristocrats trick the knight and his squire into blindfolding them-

selves and mounting a wooden horse, Clavileño, which they are told is magic and will fly them to the outer reaches of the world. The under- lings of the Duke and Duchess blow winds upon our heroes with great billows as they reach the “realm of the air.” Turning the wooden peg in the horse’s head that he believes controls the horse’s speed, Don Quixote says, “If we go on climbing at this rate we shall soon strike the region of fire, and I do not know how to manage this peg so as not to mount so high that we shall scorch.”8 Their tormentors then brush their faces with torches to convince them that they have indeed reached the realm of fire at the edge of the cosmos.

Anaximander ◆ 21

This magical episode “takes place” some two thousand years after the death of Anaximander and sixty years after the death of Copernicus, so people might have come to realize by then that Anaxi- mander was wrong.

Anaximenes

Some of Anaximander’s followers asked, “How much better is an ‘unspecific, indeterminate something-or-other’ than nothing at all?” They decided that it was no better, that in fact it was the same as nothing at all, and knowing that ex nihilo nihil (from nothing comes nothing), they went on searching for the mysterious ultimate stuff.

The next philosopher, Anaximenes (ca. 545 B.C.E.), thought it was air.

22 ◆ Chapter 1 The Pre-Socratic Philosophers

The air that we experience (“commonsense air”) is a halfway house between all the other forms into which “primordial air” can be transformed through condensation and rarefaction. The commenta- tor, Theophrastus, says:

Anaximenes . . . like Anaximander, declares that the underlying nature is one and boundless, but not indeterminate as Anaximander held, but definite, saying that it is air. It differs in rarity and density according to the substances [it becomes]. Becoming finer it comes to be fire; being condensed it comes to be wind, then cloud, and when still further condensed it becomes water, then earth, then stones, and the rest come to be out of these.9

With the idea of condensation and rarefaction, Anaximenes con- tinued the project of reductionism. He introduced the important claim that all differences in quality are really differences in quantity ( just more or less stuff packed into a specific space), an idea with which many scientists would agree today.

These first three philosophers, Thales, Anaximander, and Anaxim- enes, are known as the Milesians because they all came from the Greek colony of Miletus on the Per- sian coast and because they con- stitute the first school of philoso- phy. Despite the differences among them, they shared a number of characteristics, some of which would eventually become part of the Western scientific tradition: a desire for simple explanations, a reliance on observation to sup- port their theories, a commitment to naturalism (the view that natural phenomena should be explained in terms of other natural phenomena), and monism (the view that ultimately there is only one kind of “stuff”).

Anaximenes ◆ 23

The School of Miletus ended when the tenuous peace between the Greek outpost and Persia collapsed and the Persians overran the city, leaving behind much destruction and death. According to the historian Herodotus, the Athenians were so distressed at the fall of Miletus that they burst into tears in the theater when the playwright Phrynichus produced his drama “The Capture of Miletus.” The government banned his play and fined the author one thousand drachmas for damage to public morals.

Pythagoras

The Milesians’ successor, Pythagoras (ca. 572–ca. 500 B.C.E.), from the island of Samos, near Miletus, did not seek ultimacy in some material element, as his predecessors had done. Rather, he held the curious view that all things are numbers. Literally under- stood, this view seems absurd, but Pythagoras meant, among other things, that a correct description of reality must be expressed in terms of mathematical formulas. From our science classes we are familiar with a great number of laws of nature, all of which can be written out in mathematical formulas (for example, the law of gravitation, the three laws of motion, the three laws of thermodynamics, the law of reflection, Bernoulli’s law, Mendel’s three laws). Pythagoras is the great-great-grandfather of the view that the totality of reality can be expressed in terms of mathe- matical laws.

Very little is known about Pythagoras himself. Nothing he wrote has survived. It is almost impossible to sort out Pythagoras’s own views from those of his followers, who created various Pythagorean monastic colonies throughout the Greek world during the next sev- eral hundred years. He seems to have been not primarily a mathema- tician but a numerologist; that is, he was interested in the mystical significance of numbers. For instance, because the Pythagoreans thought that the number 10 was divine, they concluded that what we

24 ◆ Chapter 1 The Pre-Socratic Philosophers

would today call the solar system had ten members. This theory turns out to be roughly correct—the sun and nine planets—but not for Pythagoras’s reasons.

Nevertheless, he anticipated the bulk of Euclid’s writings on geometry and discovered the ratios of concord between musical sound and number. From this discovery he deduced a mathematical harmony throughout the universe, a view that led to the doctrine of “the music of the spheres.” The ten celestial bodies move, and all motion produces sound. Therefore, the motion of the ten celestial bodies—being divine—produces divine sounds. Their music is the eternal background sound against which all sound in the world is contrasted. Normally, we hear only the “sound in the world” and are

Pythagoras ◆ 25

unable to hear the background harmony. But a certain mystical stance allows us to ignore the sound of the world and to hear only the divine music of the spheres.

The influence of Pythagoras was so great that the School of Pythagoreans lasted almost 400 years. The spell he cast on Plato alone would be enough to guarantee Pythagoras a permanent place in the history of philosophy. (We shall see that Plato turns out to be the most important philosopher of the Greek period and that he was a fine mathematician as well.) With hindsight, we can now look at Pythagoras’s work and see those features of it that mark him and his followers as true philosophers. Nevertheless, it is only artificially that we distinguish that portion of Pythagorean thought that we declare to be philosophical. We should not ignore the less scientific aspect of Pythagoras’s teachings, which to him were all part of a seamless whole. He was the leader of a religious cult whose members had to obey a strict number of esoteric rules based on asceticism, numerology, and vegetarianism.

26 ◆ Chapter 1 The Pre-Socratic Philosophers

Despite their vegetarianism, Pythagoreans had to forswear eating beans because eating beans is a form of cannibalism. A close look at the inside of a bean reveals that each one contains a small, embryonic human being (or human bean, as the case may be).

Heraclitus

The next philosopher to demand our attention is Heraclitus (ca. 470 B.C.E.) of Ephesus, only a few miles from Miletus. Almost 100 trust- worthy passages from Heraclitus’s book remain for our perusal. We know more about what Heraclitus actually said than we know about any other pre-Socratic philosopher. Unfortunately, we don’t necessar- ily know more about what he meant. Like Anaximander, Heraclitus wrote in prose, but he chose to express himself in aphorisms—short, pithy outbursts with puzzling messages that seem to dare the

Heraclitus ◆ 27

reader to make sense of them. Rather than review the great varieties of scholarly effort in recent years trying to convey the many possible meanings of Heraclitus’s fragments, here I concentrate on the meaning attributed to Heraclitus’s views by the generations that followed him in the Greek and Roman world in the years after his death. The picture that emerges from the com- mentators of that early period is fairly uniform, if perhaps misguided, but after all, that picture has guaranteed Heraclitus’s fame for centuries and has been influential in the history of ideas.

One of Heraclitus’s most famous aphorisms concerns fire. He wrote: “There is an exchange of all things for fire and of fire for all things.”10 Many commentators understood Heraclitus to be naming fire as the basic stuff of reality and therefore to be in the line of Mile-

28 ◆ Chapter 1 The Pre-Socratic Philosophers

Milesian cosmologists who tried to reduce all things to one element. Others realized that Heraclitus was using the image of fire in a more subtle, figurative sense. There is something about the nature of fire that gives insight into both the appearance of stability (the flame’s form is stable) and the fact of change (in the flame, everything changes).

Heraclitus drew some striking conclusions from this vision:

Reality is composed not of a number of things but of a process of continual creation and destruction.

“War is father and king of all.” “Conflict is justice.”11

Heraclitus ◆ 29

But these passages too should be understood symbolically and not literally.

Another one of Heraclitus’s aphorisms evokes the image of flow- ing water:

“You cannot step into the same river twice.”12

Heraclitus explained this idea by saying “Everything flows and nothing abides; everything gives way and nothing stays fixed.”13 Commenta- tors interpreted Heraclitus to be saying that the only thing that does not change is change itself.

Heraclitus was called the Dark One and the Obscure One because of the difficulty of his aphorisms. Justifiably or not, his ideas were interpreted pessimistically by later Greeks, and this understanding was handed down to posterity. According to this interpretation, his ideas create more than merely a philosophy—they constitute a mood, almost a worldview of nostalgia and loss:

You can’t go home again. Your childhood is lost. The friends of your youth are gone. Your present is slipping away from you. Nothing is ever the same.

30 ◆ Chapter 1 The Pre-Socratic Philosophers

Nevertheless, there was something positive in the Heraclitean phi- losophy. An unobserv- able Logos—a logic— governed change that made change a ratio- nal phenomenon

rather than the chaotic, arbitrary one it

appeared to be. Heracli- tus wrote: “Logos is

always so.”14 This Logos doctrine deeply impressed

Plato and eventually became the basis of the notion of the laws of nature. It is also directly related to a doctrine claimed by Christian- ity. Both God and Christ are equated with Logos in the Gospel of John: “In the beginning was the Word [Logos], and the Word [Logos] was with God and the Word [Logos] was God” (John 1:1); “And the Word [Logos] was made flesh, and dwelt among us” (John 1:14).

Parmenides

Heraclitus’s successor Parmenides (ca. 515–ca. 440 B.C.E.) went a step further than his predecessor.

In effect, he said that you can’t step in the same river once.

Parmenides begins with what he takes to be a self-evident truth: “It is.” This claim is not empirical—not one derived from observation; rather, it is a truth of Reason. It cannot even be denied without self- contradiction. If you say, “It is not” (i.e., nothing exists), then you’ve proved that “It is,” for if nothing exists, it’s not nothing; rather it is something.

Parmenides ◆ 31

Parmenides believed that Being is rational, that only what can be thought can exist. Since “noth- ing” cannot be thought (without thinking of it as something), there is no nothing, there is only Being. From the mere idea of Being it follows that Being is uncreated, inde- structible, eternal, and indivisible. Fur- thermore, Being is spherical, because only a sphere is equally real in all directions. (Maybe this notion is

related to the idea of the twentieth-century physi- cist Albert Einstein, who claimed that space is

curved?) Being has no holes (no vacuum) because, if Being is, there can’t be any place

where Being is not. From this argument it follows that

motion is impossible because motion would involve Being going from where Being is to where Being isn’t (but there

can’t be any such place as the place where Being isn’t).

In fact, for Parmenides the very idea of empty space was an impossible idea.

Either space is a thing, in which case it is some- thing and not nothing, or it is nothing, in which

case it does not exist. Because all thought must

32 ◆ Chapter 1 The Pre-Socratic Philosophers

You Cannot Step in the Same River Once

have an object and because nothing is not an object, the idea of nothing is a self-contradictory idea.

It must be obvious to you that Parmenides has strayed a long way from common sense and from the facts that are revealed to us by the senses of sight, touch, hearing, smell, and taste—and primary among those facts is that motion exists and that things change. But if people laughed at Parmenides, they didn’t laugh for long, because he soon had a powerful ally.

Zeno

The sly old fox Zeno of Elea (ca. 490 B.C.E.– ?) wrote a now-famous series of paradoxes in which he defended Parmenides’ outrageous views by “proving” the impossibility of motion using a method known as reductio ad absurdum.

In this form of argument, you begin by accepting your opponent’s conclusions, and you demonstrate that they lead logically to an absurdity or a contradiction.

Zeno argued that, even granting motion, you could never arrive anywhere, not even to such a simple goal as a door. Before you can

Zeno ◆ 33

get to the door, you must go halfway, but before you can go halfway, you must go halfway of the remaining halfway, but before you can do that, you must go halfway of halfway, but before you can go halfway, you must go halfway. When does this argument end? Never! It goes on to infinity. Therefore, motion would be impossible even if it were possible.

34 ◆ Chapter 1 The Pre-Socratic Philosophers

In yet another of his paradoxes, Zeno demonstrated that in a race between Achilles and a tortoise, if Achilles gave the tortoise a head start (as would only be fair), the swift runner could never over- take the lumbering reptile. Before Achilles could pass the tortoise, he must arrive at the point at which the tortoise used to be; but given the hypothesis of motion, the tortoise will never still be there. He will have moved on. This paradox will forever be the case. When Achilles arrives at a point at which the tortoise was, the tortoise will have progressed. Achilles can never catch him.

The conclusions of these paradoxical arguments of Zeno defend- ing the views of his master, Parmenides, may seem absurd to you, but they are actually derived from the mathematical notion of the infinite divisibility of all numbers and, indeed, of all matter. Zeno’s arguments are still studied in postgraduate courses on the foundations of mathematics. Zeno is forcing us to choose between mathematics and sensory information. It is well known that the senses often deceive us, so we should choose the certainty of mathematics. With that suggestion Parmenides and Zeno caused a crisis in Greek phi- losophy. They radicalized the distinction between information based on the five senses and that based on pure reason (a distinction that would later develop into two schools of philosophy: empiricism and rationalism). Furthermore, they forced a reevaluation of the monistic

Zeno ◆ 35

presupposition accepted by all Greeks heretofore (namely, the view

that reality is com- posed of one thing),

because thinkers came to realize that

such a view led directly to Parmenides’ conclusions. It appeared that philosophers either would have to accept Parmenides’ shocking arguments or they would have to give up monism. In fact, they gave up monism.

Empedocles

The next group of philosophers are known as pluralists, precisely because they were unable to accept the monolithic stillness of Parmenides’ Being. Therefore, they were forced to believe that ultimate reality is com- posed of a plu- rality of things rather than of only one kind of thing.

The first of this group was Empedocles (?–ca. 440 B.C.E.), a citizen of the Greek colony of Acragas on the

36 ◆ Chapter 1 The Pre-Socratic Philosophers

Is Reality One Thing?

Or Many?

island of Sicily, who believed that everything was composed of the simplest parts of the four elements: fire, air, earth, and water. He called these elements the “four roots.”

But in the face of Zeno’s critique of motion, Empedocles believed he needed to posit two forces to explain change and movement. These forces he called Love and Strife. Love is the force of unity,

bringing together unrelated items to produce new creations, and Strife

is the force of destruction, breaking down old unities

into fragments.

(A curious version of Empedocles’ theory was later accepted by the twentieth-century psycho- analyst Sigmund Freud, who named the two forces Eros and Thanatos [the life instinct and the death instinct]. Freud agreed with Empedocles that these forces formed the bases of all organic matter.)

The first theory of evolution developed out of Empedocles’ sys- tem. Love brings together certain kinds of monsters. “Many heads grew up without necks, and arms were wandering about naked, bereft of shoulders, and eyes roamed about alone with no foreheads. Many

Empedocles ◆ 37

creatures arose with double faces and double breasts, offspring of oxen with human faces, and again there sprang up children of men with oxen’s heads.”15

And those that could survive, did survive.

(Aristotle later criticized this view as “leaving too much to chance.”)

Anaxagoras

The next pluralist, Anaxagoras (ca. 500–ca. 428 B.C.E.) of Clazom- enae, near Miletus, found Empedocles’ theory too simplistic. He

replaced the “four roots” with “infinite seeds.” Each of these seeds is something like an

element in today’s chemistry; so in some ways, this theory

sounds very modern. Every object in the

world contains seeds of all elements, and in each object, the seeds of one ele- ment predominate.

38 ◆ Chapter 1 The Pre-Socratic Philosophers

“In all things, there is a portion of everything. . . . For how could hair come from what is not hair? Or flesh from what is not flesh?”16

Anaxagoras agreed with Empedocles that some force explaining motion and change was required, but he replaced Empedocles’ all too mythical figures of Love and Strife with one force, a mental one, which he called Nous, or Mind. This assumption means that the universe is organized according to an intelligent, rational order. Anaxagoras’s Nous is almost like a god who creates objects out of the seeds, or elements.

Furthermore, there is a distinction between the animate and the inanimate world in that the organic world contains Nous within it as

a self-ordering principle, whereas the inorganic world is ordered exter- nally by Nous. Nous itself is qualitatively identical everywhere, but its abilities are determined by the nature of the body that contains it. Humans aren’t any smarter than carrots, but they can do more than carrots because they have tongues, opposable thumbs, and legs. (You wouldn’t act very smart either if you were shaped like a pointy root.)

Anaxagoras ◆ 39

Notice that Anaxagoras’s theory is the first time that a philosopher distinguished clearly between living substance and “dead” matter. The anthropomorphic concept Nous looked promising to two of the most important later Greek philosophers, Socrates and Aris- totle, but eventually it disappointed them. Socrates said that at first he found it an exciting idea, but it ended up meaning nothing at all, and Aristotle said that Anaxagoras stood out “like a sober man in the midst of loose talkers.”17 Later Aristotle was disillusioned by Anaxagoras, who used “reason as a deus ex machina for the making

of the world, and when he is at a loss to tell from what cause some- thing necessarily is, then he drags reason in, but in all other cases ascribes events to anything rather than reason.”18

Leucippus and Democritus

Precisely because Anaxagoras’s view was anthropomorphic, it was still too mythical for Anaxagoras’s successors, a group of philoso- phers, led by Leucippus (ca. 460 B.C.E.–?) and Democritus (ca. 460–ca. 370 B.C.E.), known as the atomists.

They saw the world as composed of material bodies, which them- selves are composed of groups of “atoms.” The Greek word atomon (atomon) means “indivisible,” that which cannot be split.

Democritus made each atom a little piece of Parmenidean Being (uncreated, indestructible, eternal, indivisible, containing no “holes”) and set them moving through empty space traversing absolutely

necessary paths that are determined by rigid natural laws.

So, contrary to Parmenides’ view, both empty space and motion are real. Moreover, like atoms themselves, motion and space

Leucippus and Democritus ◆ 41

are natural and basic, admitting of no further analysis. It is the appearance of inertia and not that of motion that needs explaining, and Democritus’s explanation, like that of Heraclitus, is that inertia is an illusion. That is to say, it is explained away. Thus, by the year 370 B.C.E., Greek philosophy had been led to a thoroughgoing materialism and a rigorous determinism. There was nothing in the world but material bodies in motion and there was no freedom, only necessity.

What had the pre-Socratic philosophers achieved? Through them, a special kind of thinking had broken free from its mythical and religious ancestors, developing its own

methods and content—a kind of thinking that would soon evolve into what today we know as science and phi- losophy. Looking back at the pre-Socratics, we see a direct lineage between them and the great thinkers of our own time: The dichotomy between reason and the senses that the German philosopher Immanuel Kant was to

resolve in the eighteenth century was first made clear by the pre- Socratics; the first attempt to formulate a theory of evolution was made by them; and the first effort to solve the riddle of how mathe- matical numbers hold sway over the flux of reality—all this we see as a more or less unbroken genealogy from their time to ours.

But to the Greeks of the fifth century, the pre-Socratic philoso- phers had left a legacy of confusion.

The only thing the philosophers had succeeded in doing was to undermine the traditional religious and moral values, leaving nothing substantial in their place. (As the Greek dramatist Aristophanes

Besides, “the times they were a’ changin’,” socially and politically as well as intellectually. The old aristocracy, dedicated to the noble values of the Homeric legends, was losing ground to a new mercantile class, which was no longer interested in the virtues of Honor, Courage, and Fidelity but in Power and Success. How was the new class to achieve these virtues in an incipient democracy? Through politics. And the access to political power was then, as it is today, through the study of rhetoric (read “law”)—the art of swaying the masses with eloquent, though not necessarily truthful, argumentation.

Topics for Consideration

1. What is the problem of “the One and the Many” that presented itself to the early Greek philosophers? Pick three pre-Socratics with very differ- ent solutions to this problem and contrast their views.

2. Apply the distinction you learned in the Introduction between Mythos and Logos to the Milesian philosophers Thales, Anaximander, and Anaximenes. Which camp are they in?

3. If you lived in the Greek world during the sixth century B.C.E. and knew only what could be known at that period, which of the basic substances or entities would you choose as the foundation of reality, based on your own observations? Why? (Before you start, read the next topic.)

Topics for Consideration ◆ 45

a. Water (Thales)

b. Air (Anaximenes)

c. Fire (roughly, Heraclitus)

d. Earth (very roughly, Democritus)

e. An indeterminate “stuff” (Anaximander)

f. Numbers (roughly, Pythagoras)

4. Same question as the previous topic, with this qualification: Based on what you now know at the beginning of the twenty-first century, but still limited to the categories a through f, which letter or combination of let- ters would you choose?

5. Contrast as dramatically as you can the theses of Heraclitus and Parmenides. What do you think would be the practical consequences, if any, of seriously accepting the philosophical claim of Heraclitus? of Parmenides?

6. Explain why Zeno’s paradoxes provoked such a deep crisis in the intellec- tual environment of ancient Greece. Show how philosophical progress after Zeno required some compromise between the views of the Par- menidean camp and those of the pre-Parmenidean camp.

These post-Aristotelian sources are primarily Theophrastus (ca. 371–ca. 286 B.C.E.), a pupil of Aristotle; Simplicius, a sixth-century B.C.E. commentator on Aris- totle; Eudemus of Rhodes, who wrote around 300 B.C.E.; Hippolytus, Bishop of Rome in the third century C.E.; and Diogenes Laertius, whose books were written about 300 C.E. A readable account of recent scholarship on this topic can be found in Routledge History of Philosophy, vol. 1, From the Beginning to Plato (ed. C. C. W.

Notes ◆ 47

The Sophists

Because of the social shift toward political power and the study of rhetoric, it was no surprise, then, that the next group of philosophers were not really philosophers as such but rhetoricians who became known as Sophists (“wise guys”). They traveled from city to city, charging admission to their lectures—lectures not on the nature of

48

2 The Athenian Period

Fifth and Fourth Centuries B.C.E.

reality or truth but on the nature of power and persuasion. Plato and Aristotle wrote a lot about the Sophists, and according to the pic- ture that they handed down to us, not just skepticism but cynicism became the rule of the day.

Protagoras

Perhaps the most famous (and least cynical) of the Sophists was Protagoras (ca. 490–ca. 422 B.C.E.). He taught that the way to achieve success is through a careful and prudent acceptance of tra- ditional customs—not because they are true, but because an under- standing and manipulation of them is expedient. For Protagoras all customs were relative, not absolute. In fact, everything is relative to human subjectivity. Protagoras’s famous claim is homo mensura— man is the measure.

Protagoras’s emphasis on subjectivity, relativism, and expedi- ency is the backbone of all sophism. According to some stories, Protagoras was indicted for blasphemy, and his book on the gods

was burned publicly in Athens— yet one of the few remaining fragments of his writings con- cerning religion states, “As for the gods, I have no way of knowing either that they exist or that they do not exist.”2

Gorgias

Another famous Sophist was Gorgias (ca. 483–375 B.C.E.). He seems to have wanted to dethrone philosophy and replace it with rhetoric. In his lectures and in a book he wrote, he “proved” the following theses:

1. There is nothing. 2. If there were anything, no one could know it. 3. If anyone did know it, no one could communicate it.

50 ◆ Chapter 2 The Athenian Period

THE RE IS N

OTHING!. . .

Hey! W here did everybodygo?

Gods? I don’t know about gods.

The point, of course, is that if you can “prove” these absurdities, you can “prove” anything. Gorgias is not teaching us some astound- ing truth about reality; he is teaching us how to win arguments, no matter how ridiculous our thesis may be.

Thrasymachus

Yet another Sophist was Thrasymachus, who is known for the claim “Justice is in the interest of the stronger.” That is to say, might makes right. According to him, all disputation about morality is empty, except insofar as it is reducible to a struggle for power.

The Sophists ◆ 51

Callicles and Critias

According to the accounts handed down to us, two of the most cyni- cal Sophists were Callicles and Critias.

Callicles claimed that traditional morality is just a clever way for the weak masses to shackle the strong individual. He taught that the strong should throw off these shackles and that doing so would be somehow “naturally right.” What matters is power, not justice. But why is power good? Because it is conducive to survival. And why is survival good? Because it allows us to seek pleasure—pleasure in food, drink, and sex. Pleasure is what the enlightened person aims for, qualitatively and quantitatively. The traditional Greek virtue of moderation is for the simple and the feeble.

Critias (who was to become the cruelest of the Thirty Tyrants, the men who overturned the democracy and temporarily established an oligarchical dictatorship) taught that the clever ruler controls subjects by encouraging their fear of nonexistent gods.

52 ◆ Chapter 2 The Athenian Period

So we see that the essence of sophism comprises subjectivism, skepticism, and nihilism. Everything the pre-Socratics stood for is devalued. There is no objective reality, and if there were, the human mind could not fathom it. What matters is not truth but manipulation and expediency. No wonder Socrates was so offended by sophism.

Yet we must say a few kind words about sophism despite its negativism. First, many of the Sophists were skilled politicians who actually contributed to the history of democracy. Second, history’s animosity toward them is based mostly on reports we have of them

from Socrates and Plato, who were ene- mies of the Sophists. Third, and most important, sophism had the positive effect of making human beings aware not of the cosmos but of themselves as objects of interest. In pre-Socratic phi- losophy, there was no special considera- tion of the human. Suddenly, with Pro- tagoras’s “man is the measure,” humans became interested in themselves.

The Sophists ◆ 53

ZEUS HERA POSEIDON

Socrates

The Sophists, who were professional teachers, met their match in a man who was possibly the greatest teacher of all time, Socrates (469–399 B.C.E.). Despite his overall disagreement with them, Socrates followed the Sophists’ lead in turning away from the study of the cosmos and concentrating on the case of the human. But unlike the way the Sophists discoursed about the human being, Socrates wanted to base all argumentation on objectively valid defini- tions. To say “man is the measure” is saying very little if one does not know what “man” is. In the Theatetus, Socrates says:

Socrates’ discourse moved in two directions—outward, to objective definitions, and inward, to discover the inner person, the soul, which, for Socrates, was the source of all truth. Such a search is not to be conducted at a weekend lecture but is the quest of a lifetime.

54 ◆ Chapter 2 The Athenian Period

I am surprised that Protagoras did not say

that a pig, or a dog-faced baboon, is the measure

of all things.

All is fruit

All is garbage

Socrates was hardly ever able to answer the questions he asked. Nevertheless, the query had to continue, for, as we know from his famous dictum,

The unexamined life is not worth living.3

Socrates ◆ 55

Truth (trooth): verity, conformity with fact. Honesty, integrity.

Socrates spent much of his time in the streets and market- place of Athens, querying every man he met about whether that man knew anything. Socrates said that, if there was an afterlife, he would pose the same question to the shades in Hades.

Ironically, Socrates himself professed to know nothing. The ora- cle at Delphi said that therefore Socrates was the wisest of all men. Socrates at least knew that he knew nothing, whereas the others falsely believed themselves to know something.

Socrates himself wrote no books, but his conversations were remembered by his disciple Plato and later published by him as dialogues. Very often these Socratic dialogues will emphasize a spe- cific philosophical question, such as “What is piety?” (in the dialogue titled Euthyphro), “What is justice?” (in Republic), “What is virtue?” (in Meno), “What is meaning?”(in Sophist), “What is love?” (in Sympo- sium). The typical Socratic dialogue has three divisions:

56 ◆ Chapter 2 The Athenian Period

1. A question is posed (e.g., the ques- tion of what virtue is, or justice, or truth, or beauty); Socrates becomes excited and enthusiastic to find someone who claims to know something.

2. Socrates finds “minor flaws” in his compan- ion’s definition and slowly begins to unravel it, forcing his partner to admit igno- rance. (In one dialogue, Socrates’ target actually ends up in tears.)

3. An agreement is reached by the two admittedly ignorant companions to pursue the truth seriously. Almost all the dialogues end inconclusively. Of course, they must do so. Socrates cannot give his disciples the truth. Each of us must find it out for ourselves.

In his quest for truth, Socrates managed to offend many of the powerful and pompous fig- ures of Athens. (In fairness to his accusers, it should be mentioned that some citizens suspected Socrates of preferring the values of Sparta to those of his native Athens. Sparta was Athens’s enemy in

Socrates ◆ 57

the Peloponnesian War.) Socrates’ enemies conspired against him, getting him indicted for teaching false doctrines, for impiety, and for corrupting the youth. They brought him to trial hoping to humiliate him by forcing him to grovel and beg for mercy.

Far from groveling, at his trial Socrates maligned his prosecu- tors and angered the unruly jury of 500 by lecturing to them about their ignorance. Furthermore, when asked to suggest his own punish- ment, Socrates recommended that the Athenians give him free board and lodging in the town hall. The enraged jury condemned him to death by a vote of 280 to 220.

Ashamed of their act and embarrassed that they were about to put to death their most eminent citizen, the Athenians were prepared to look the other way when Socrates’ prison guard was bribed to allow Socrates to escape.

Despite the pleas of his friends, Socrates refused to do so, say- ing that if he broke the law by escaping, he would be declaring himself an enemy of all laws. So he drank the hemlock and philosophized with his friends to the last moment. In death, he became the universal symbol of martyrdom for the Truth.

58 ◆ Chapter 2 The Athenian Period

Plato

The most important of Socrates’ young disciples was Plato (427– 347 B.C.E.), who was one of the most powerful thinkers in history. He is also the founder of the first university, the Academy, where

students read as exercises the Socratic dialogues that Plato had written.

Because of his authorship, it is often difficult to distinguish between the thought of Socrates and that of Plato. In general, we can say that Plato’s philosophy was more metaphysical, more systematic, and more other-worldly than Socrates’ philoso- phy was.

The essence of Plato’s philosophy is depicted allegorically in the Myth of the Cave,

which appears in his most important work, the Republic. In this myth Plato has Socrates con-

ceive the following vision: Imagine prisoners

Plato ◆ 59

chained in such a way that they face the back wall of a cave. There they have been for life and can see nothing of themselves or of each other. They see only shadows on the wall of the cave.

These shadows are cast by a fire that burns on a ledge above and behind them. Between the fire and the prisoners is a wall-lined path along which people walk carrying vases, statues, and other artifacts on their heads. The prisoners hear the echoes of voices and see the shadows of the arti- facts, and they mistake

60 ◆ Chapter 2 The Athenian Period

these echoes and shadows for reality.

Plato has Socra- tes imagine that one prisoner is unchained, turned around, and forced to look at the true source of the shadows. But the fire pains his eyes. He prefers the pleasant deception of the shadows.

Behind and above the fire is the mouth of the cave, and outside in the bright sunlight (only a little of which trickles into the cave) are trees, rivers, mountains, and sky.

Now the former prisoner is forced up the “steep and rugged ascent”4 (Plato’s allegory of education) and brought to the sunlit exterior world. But the light blinds him. He must first look at the shadows of the trees (he is used to shadows), then at the trees and

Plato ◆ 61

mountains. Finally he is able to see the sun itself (the allegory of enlightenment).

Plato suggests that if this enlightened man were to return to the cave, he would appear ridicu- lous because he would see sunspots everywhere and not be able to penetrate the darkness.

And if he tried to liber- ate his fellow prisoners, they would be so angry at him for disturbing their illusions that they would set upon him and kill him—a clear allu- sion to the death of Socrates.

62 ◆ Chapter 2 The Athenian Period

The allegory of the liberation of the slave from darkness, deceit, and untruth and the slave’s hard journey into the light and warmth of the Truth has inspired many philosophers and social leaders. But Plato meant it as more than just a poetic vision. He also gave it a precise technical application, seen in his Simile of the Line, also found in the Republic.5 On the left side of the Line we have an episte- mology (theory of knowledge); on the right side, an ontology (theory of being). In addition, we have an implicit ethics (moral theory) and aesthetics (theory of beauty). The totality constitutes Plato’s metaphysics (general worldview).

The Line reveals the hierarchical nature of the objects of all these disciplines. Reality is a hierarchy of being, of knowledge, and of value, with objects that are most real, most certain, and most valuable at the top. A descending ontological, epistemological, moral, and aesthetic scale cascades down from the highest level in the guise of a mathematically organized series of originals and copies. The whole of the visible world is a copy of the whole of the intelligible

world, yet each of these worlds is also divided into originals and copies.

For each state of being (right side of the Line), there is a corre- sponding state of awareness (left side). The lowest state of aware- ness is that of Conjecture, which has as its object Images, such as shadows and reflections (or images on the TV screen and video games).

The person in a state of conjecture mistakes an image for real- ity. This level on the Line corresponds to the situation of the cave- bound prisoners watching the shadows.

The next level, that of Belief, has as its object a particular thing— say, a particular horse or a particular act of justice. Like Conjecture, Belief still does not com- prise knowledge but remains in the sphere of Opinion, still grounded in the uncertainties of sense perception. It is not yet “concep- tual.” It is not yet directed by theory (hypothemenoi) or by a definition in terms of necessary and sufficient conditions. (The per- son in a state of belief is like a prisoner who sees the artifact held above the wall inside the cave.)

Opinion and the objects of which it is aware are all sustained by the sun. Without the sun, there could be no horse and no image of a horse, nor could we be aware of them in the absence of light.

64 ◆ Chapter 2 The Athenian Period

Good night, and have a nice

weekend. Chee, tanks.

You too, Pete.

For Opinion to become Knowledge, the particular object must be raised to the level of theory. (This stage, Understanding, corresponds to the status of the released prisoner looking at the shadows of the trees in the world above the cave.)

Plato ◆ 65

How do you know that’s a horse?

Are you blind? Take a look! A horse

is a horse.

He doesn’t really know, you know.

How do you know it’s a horse?

A horse is a domesticatable quadruped with closed hoofs and 32 pairs of chromosomes; and that creature is such an entity. Ergo it is a horse!

Actually it’s a

zebra.

He knows!

But according to Plato, theories and definitions are not empiri- cal generalizations dependent on particular cases and abstracted from them. To the contrary, rather than coming from below on the Line, theories are themselves images of something higher—what Plato calls the Forms. (In the same way that shadows and reflec- tions are merely images of particular things, so theories or concepts are the shadows of the Forms.) When one beholds the Forms, one exercises Pure Reason, and one is like the liberated prisoner who gazed upon the trees and mountains in the sunlit upper world.

Plato’s conception of the Forms is very complicated, but I can simplify it by saying that Forms are the eternal truths that are the source of all Reality. Consider, for example, the concept of beauty. Things in the sensible world are beautiful to the extent that they imi- tate or participate in Beauty. However, these beautiful things will break, grow old, or die. But Beauty itself (the Form) is eternal. It will

always be. The same can be said of Truth and Justice. (Also, more embarrassingly, of Horseness or of Toothpickness.)

Furthermore, just as the sensible world and awareness of it are dependent on the sun, so are the Forms and knowledge of them dependent on the Good, which is a Superform, or the Form of all Forms. The state of beholding the Good is represented in the Myth of the Cave by the released prisoner beholding the sun itself. Plato’s theory is such that the whole of Reality is founded upon the Good, which is Reality’s source of being. And all Knowledge is ultimately knowledge of the Good.

If you are puzzled by Plato’s conception of the Good, you are in “good” company. Philosophers have debated its meaning for cen- turies. Clearly it plays a role very much like that of God in certain theological systems. For example, referring to the Simile of the Line, Plato calls the sun a “god” and claims that it is “the offspring of the Good.”6 The Good is the source of being, knowledge, and truth but is something even “more beautiful”7 than these. It is not surprising that

Plato ◆ 67

many religiously oriented philosophers in the Middle Ages and the Renaissance—two periods in which Plato’s influence was powerful— treated the Good as a mystical category. Something that is beyond being and knowledge is something that might be grasped only by a state of mind that transcends rationality. More orthodox religious thinkers treated the Good as identical to God. It was along these lines that Plato deeply influenced the development of Christianity, Judaism, and Islam. It would be a bad pun (and an anachronistic one, since the English language did not yet exist in Plato’s time), but an illuminating one, to say that early Christianity dropped one “o” from “Good” and changed the “u” to an “o” in “sun” to create an icon of the relation between God and Christ.

Whatever Plato means by “the Good,” he optimistically holds that if one ever comes to know the Good, one becomes good. Igno- rance is the only error. No one would willingly do wrong.

How can we learn the Truth? Where can we find the Forms, and especially the Form of the Good? Who can

teach us? Plato had curious answers to these questions. In the dialogue called Meno, Plato had an un- schooled slave boy solve a diffi- cult mathematical problem by answering affirmatively or negatively a series of simple questions posed by Socra- tes. Plato concluded from this episode that the slave boy always knew the answer but didn’t know that he knew. All Truth comes from within—from the soul. One’s immortal soul is born with the Truth, having beheld the Forms in their purity before

68 ◆ Chapter 2 The Athenian Period

its embodiment. Birth, or the embodiment of the soul, is so trau- matic that one forgets what one knows and must spend the rest of life plumbing the depths of the soul to recover what one already knows—hence, Plato’s strange doctrine that all Knowledge is recol- lection. Now we see Socrates’ role as that of helping his student to remember, just as the psychoanalyst does with his or her patient today. (A modern version of Plato’s doctrine of recollection is Freud’s theory of unconscious memories.)

The Republic is well known not only for its epistemology but also for its social philosophy. The latter for Plato is a combination of psy- chology and political science. He said that the City (the “Republic”) is the individual writ large. Just as the individual’s psyche has three aspects—the appetitive, animal side; the spirited source of action; and the rational aspect—so does the ideal City have three classes —the workers and the artisans; the soldiers; and the rulers. In the psyche, the rational part must convince the spirited part to help it control the appetitive. Otherwise, there will be an unbalanced soul, and neurosis will ensue.

Similarly, in the City, the rulers must be philosophers who have beheld the Forms and there- fore know what is good. They must train the military caste to help control the naturally unruly peas- ants. The latter will be allowed to use money, own property, and wear decorations in moderation, but the members of the top two classes, who understand the corrupting effect of greed, will live in an aus- tere, absolute communism, sleep- ing and eating together, owning no property, receiving no salary, and having sexual relations on a pre- arranged schedule with partners shared by all. These rules will guar- antee that the City will not be frenzied and anarchic—a strange beginning for the discipline of polit- ical science (one from which it has still not recovered)!

The members of the ideal City will be allowed to play simple lyres and pipes and sing patriotic, uplifting songs, but most artists will be drummed out of the Repub- lic. This maltreatment has four reasons: (1) ontological—Because art deals with images (the lowest rung in the Simile of the Line), art is an imitation of an imitation. (Art is “three removes from the throne.”);8 (2) epistemological—The artist, at the conjectural stage,

70 ◆ Chapter 2 The Athenian Period

knows nothing but claims to know some- thing; (3) aesthetical—Art expresses itself in sensual images; hence, it distracts us from Beauty itself, which is purely intellectual; (4) moral—Art is created by and appeals to the ap- petite side of the soul (Freud’s id). Art is either erotic or violent or both; hence, it is an incitement to anarchy. Even Homer must be censored, for he too is guilty of the artist’s crimes: fraudulence, igno- rance, and immorality.

(The whole enterprise of the Republic can be viewed as a plea that philosophy take over the role that art had hitherto played in Greek culture.)

Plato did not live to see the inauguration of his ideal state nor to see the installation of a Philosopher King who would know the Good, but the legacy that Plato left is still very much with us, for better or for worse. The eminent British-American philosopher Alfred North Whitehead once said that the history of philosophy is merely a series of footnotes to the Republic.

Plato’s Simile of the Line would, to a great extent, lay out the framework of Western metaphysical thought from his time to ours. Many of the philosophers mentioned in this book were influenced deeply by Plato (Aristotle, the Stoics, the Neoplatonists, Saint Augustine, Saint Anselm, Saint Thomas Aquinas, Descartes, Spi- noza, Kant, Hegel, Schopenhauer, Kierkegaard, Marx, Russell, and Whitehead, among others). Even those philosophers who hated Plato’s philosophy, such as Nietzsche, often admired his intellectual power—a power that even Nietzsche could not escape.

Plato ◆ 71

Aristotle

Plato’s influence is clearly seen in the thought of one of his best students, Aristotle (384–322 B.C.E.). Aristotle, born in Stagira, spent twenty years at Plato’s academy. Soon after the death of the master, Aristotle left the school because of disagreements with its new chiefs, and he founded an academy of his own, the Lyceum. In Aristotle’s school, Platonic philosophy was taught, but it was also criticized.

The main thrust of Aristotle’s dispute with his mentor con- cerned the latter’s other-worldliness. For Plato, there were two worlds: the unspeakably lofty world of Forms, and the world of mere

72 ◆ Chapter 2 The Athenian Period

“things,” which is but a poor imitation of the former. Aristotle contra- dicted this view, asserting that there is only one world and that we are right smack in the middle of it. In criticizing Plato, Aristotle asked: If Forms are essences of things, how can they exist separated from things? If they are the cause of things, how can they exist in a different world? And a most telling criticism has to do with the prob- lem of change and motion, which the early Greeks had tried to solve.

They thought either that stability was an illusion (the view of Heraclitus, for example) or that motion was an illusion (the view of Parmenides). Plato had tried to resolve the dilemma by acknowledging the insights of both Heraclitus and Parmenides. The former’s world is the unstable and transient realm of the visible. The latter’s world

Aristotle ◆ 73

is the immutable realm of the intelligible composed of the eternally unchanging Forms, which themselves are poorly reflected in the transitory world of the visi- ble. But did Plato’s compro- mise really solve the prob- lem of motion and change? Is it really comprehensible to explain “changing things” by saying that they are bad imitations of unchanging things?
