A Critical History of Greek Philosophy Part 8

No doubt this was due in part to the unmethodical and unsystematic manner in which Socrates developed his thought, and this, in its turn, was due to his conversational style of philosophizing. For it is not possible to develop systematic thinking in the course of casual conversations. But in part, too, it was due to the very universality of the man's genius. He was broad enough to realize that it is not possible to tie down virtue in any single narrow formula, which shall serve as a practical receipt for action in all the infinitely various circ.u.mstances of life. So that, in spite of the fact that his whole principle lay in the method of definitions, Socrates, in fact, left his followers without any definition of the supreme concept of his philosophy, virtue. It was upon this point, therefore, that the followers of Socrates disagreed. They all agreed that virtue is the sole end of life, but they developed different ideas as to what sort of life is in fact virtuous.

The Cynics.

Antisthenes, the founder of the Cynic School, repeated the familiar propositions that virtue is founded upon knowledge, is teachable, and is one. But what aroused the admiration of Antisthenes was not Socrates, the man of intellect, the man of science, the philosopher, but Socrates, the man of independent character, who followed his own notions of right with complete indifference to the opinions of others.

This independence was in fact merely a by-product of the Socratic life. Socrates had been independent of all earthly goods and possessions, caring neither for riches nor for applause, only because his heart was set upon a greater treasure, the acquisition of wisdom.

Mere independence and indifference to the {159} opinions of others were not for him ends in themselves. He did not make fetishes of them.

But the Cynics interpreted his teaching to mean that the independence of earthly pleasures and possessions is in itself the end and object of life. This, in fact, was their definition of virtue, complete renunciation of everything that, for ordinary men, makes life worth living, absolute asceticism, and rigorous self-mortification.

Socrates, again, thinking that the only knowledge of supreme value is ethical knowledge, had exhibited a tendency to disparage other kinds of knowledge. This trait the Cynics exaggerated into a contempt for all art and learning so great as frequently to amount to ignorance and boorishness. "Virtue is sufficient for happiness," said Antisthenes, "and for virtue nothing is requisite but the strength of a Socrates; it is a matter of action, and does not require many words, or much learning." The Cynic ideal of virtue is thus purely negative; it is the absence of all desire, freedom from all wants, complete independence of all possessions. Many of them refused to own houses or any dwelling place, and wandered about as vagrants and beggars.

Diogenes, for the same reason, lived in a tub. Socrates, following single-heartedly what he knew to be good, cared nothing what the vulgar said. But this indifference to the opinion of others was, like his independence of possessions, not an end in itself. He did not interpret it to mean that he was wantonly to offend public opinion.

But the Cynics, to show their indifference, flouted public opinion, and gave frequent and disgusting exhibitions of indecency.

Virtue, for the Cynics, is alone good. Vice is the only evil. Nothing else in the world is either good or bad. {160} Everything else is "indifferent." Property, pleasure, wealth, freedom, comfort, even life itself, are not to be regarded as goods. Poverty, misery, illness, slavery, and death itself, are not to be regarded as evils. It is no better to be a freeman than a slave, for if the slave have virtue, he is in himself free, and a born ruler. Suicide is not a crime, and a man may destroy his life, not however to escape from misery and pain (for these are not ills), but to show that for him life is indifferent. And as the line between virtue and vice is absolutely definite, so is the distinction between the wise man and the fool. All men are divided into these two cla.s.ses. There is no middle term between them. Virtue being one and indivisible, either a man possesses it whole or does not possess it at all. In the former case he is a wise man, in the latter case a fool. The wise man possesses all virtue, all knowledge, all wisdom, all happiness, all perfection. The fool possesses all evil, all misery, all imperfection.

The Cyrenaics.

For the Cyrenaics, too, virtue is, at least formally, the sole object of life. It is only formally, however, because they give to virtue a definition which robbed it of all meaning. Socrates had not infrequently recommended virtue on account of the advantages which it brings. Virtue, he said, is the sole path to happiness, and he had not refrained from holding out happiness as a motive for virtue. This did not mean, however, that he did not recognize a man's duty to do the right for its own sake, and not for the sake of the advantage it brings. "Honesty," we say, "is the best policy," {161} but we do not mean thereby to deny that it is the duty of men to be honest even if it is not, in some particular case, the best policy. Socrates, however, had not been very clear upon these points, and had been unable to find any definite basis for morality, other than that of happiness. It was this side of his teaching which Aristippus now pressed to its logical conclusions, regardless of all other claims.

Doubtless virtue is the sole end of life, but the sole end of virtue is one's own advantage, that is to say, pleasure. One may as well say at once that the sole end of life is pleasure.

The influence of Protagoras and the Sophists also played its part in moulding the thought of Aristippus. Protagoras had denied the objectivity of truth, and the later Sophists had applied the same theory to morals. Each man is a law unto himself. There is no moral code binding upon the individual against his own wishes. Aristippus combined this with his doctrine of pleasure. Pleasure being the sole end of life, no moral law externally imposed can invalidate its absolute claims. Nothing is wicked, nothing evil, provided only it satisfies the individual's thirst for pleasure.

Whether such a philosophy will lead, in practice, to the complete degradation of its devotees, depends chiefly upon what sort of pleasure they have in mind. If refined and intellectual pleasures are meant, there is no reason why a comparatively good life should not result. If bodily pleasures are intended, the results are not likely to be n.o.ble. The Cyrenaics by no means wholly ignored the pleasures of the mind, but they pointed out that feelings of bodily pleasure are more potent and intense, and it was upon these, therefore, that they chiefly {162} concentrated their attention. Nevertheless they were saved from the lowest abysses of sensuality and b.e.s.t.i.a.lity by their doctrine that, in the pursuit of pleasure, the wise man must exercise prudence. Completely unrestrained pursuit of pleasure leads in fact to pain and disaster. Pain is that which has to be avoided. Therefore the wise man will remain always master of himself, will control his desires, and postpone a more urgent to a less urgent desire, if thereby in the end more pleasure and less pain will accrue to him. The Cyrenaic ideal of the wise man is the man of the world, bent indeed solely upon pleasure, restrained by no superst.i.tious scruples, yet pursuing his end with prudence, foresight, and intelligence. Such principles would, of course, admit of various interpretations, according to the temperament of the individual. We may notice two examples. Anniceris, the Cyrenaic, believed indeed that pleasure is the sole end, but set such store upon the pleasures that arise from friends.h.i.+p and family affection, that he admitted that the wise man should be ready to sacrifice himself for his friends or family--a gleam of light in the moral darkness. Hegesias, a pessimist, considered that positive enjoyment is impossible of attainment. In practice the sole end of life which can be realized is the avoidance of pain.

The Megarics.

Euclid of Megara was the founder of this school. His principle was a combination of Socraticism with Eleaticism. Virtue is knowledge, but knowledge of what? It is here that the Eleatic influence became visible. With Parmenides, the Megarics believed in the One Absolute Being. All multiplicity, all motion, are illusory. {163} the world of sense has in it no true reality. Only Being is. If virtue is knowledge, therefore, it can only be the knowledge of this Being. If the essential concept of Socrates was the Good and the essential concept of Parmenides Being, Euclid now combined the two. The Good is identified with Being. Being, the One, G.o.d, the Good, divinity, are merely different names for one and the same thing. Becoming, the many, Evil, are the names of its opposite, not-being, Multiplicity is thus identified with evil, and both are declared illusory. Evil has no real existence. The Good alone truly is. The various virtues, as benevolence, temperance, prudence, are merely different names for the one virtue, knowledge of Being.

Zeno, the Eleatic, had shown that multiplicity and motion are not only unreal but even impossible, since they are self-contradictory. The Megarics appropriated this idea, together with the dialectic of Zeno, and concluded that since not-being is impossible, Being includes all possibility. Whatever is possible is also actual. There is no such thing as a possible something, which yet does not exist.

As the Cynics found virtue in renunciation and negative independence, the Cyrenaics in the hedonistic pursuit of pleasure, so the Megarics find it in the life of philosophic contemplation, the knowledge of Being.

CHAPTER XII

PLATO

None of the predecessors of Plato had constructed a system of philosophy. What they had produced, and in great abundance, were isolated philosophical ideas, theories, hints, and suggestions. Plato was the first person in the history of the world to produce a great all-embracing system of philosophy, which has its ramifications in all departments of thought and reality. In doing this, Plato laid all previous thought under contribution. He gathered the entire harvest of Greek philosophy. All that was best in the Pythagoreans, the Eleatics, Heracleitus, and Socrates, reappears, transfigured in the system of Plato. But it is not to be imagined, on this account, that Plato was a mere eclectic, or a plagiarist, who took the best thoughts of others, and worked them into some sort of a patch-work philosophy of his own.

He was, on the contrary, in the highest degree an original thinker.

But like all great systems of thought, that of Plato grows out of the thought of previous thinkers. He does indeed appropriate the ideas of Heracleitus, Parmenides, and Socrates. But he does not leave them as he finds them. He takes them as the germs of a new development. They are the foundations, below ground, upon which he builds the palace of philosophy. In his hands, all previous thought becomes {165} transfigured under the light of a new and original principle.

1. Life and Writings.

The exact date of the birth of Plato is a matter of doubt. But the date usually given, 429-7 B.C. cannot be far wrong. He came of an aristocratic Athenian family, and was possessed of sufficient wealth to enable him to command that leisure which was essential for a life devoted to philosophy. His youth coincided with the most disastrous period of Athenian history. After a bitter struggle, which lasted over a quarter of a century, the Peloponnesian war ended in the complete downfall of Athens as a political power. And the internal affairs of the State were in no less confusion than the external. Here, as elsewhere, a triumphant democracy had developed into mob-rule. Then at the close of the Peloponnesian war, the aristocratic party again came into power with the Thirty Tyrants, among whom were some of Plato's own relatives. But the aristocratic party, so far from improving affairs, plunged at once into a reign of bloodshed, terror, and oppression. These facts have an important bearing upon the history of Plato's life. If he ever possessed any desire to adopt a political career, the actual condition of Athenian affairs must have quenched it. An aristocrat, both in thought and by birth, he could not accommodate himself to the rule of the mob. And if he ever imagined that the return of the aristocracy to power would improve matters, he must have been bitterly disillusioned by the proceedings of the Thirty Tyrants. Disgusted alike with the democracy and the aristocracy he seems to have retired into seclusion. He never once, throughout his long life, appeared as a {166} speaker in the popular a.s.sembly. He regarded the Athenian const.i.tution as past help.

Not much is known of the philosopher's youth. He composed poems. He was given the best education that an Athenian citizen of those days could obtain. His teacher, Cratylus, was a follower of Heracleitus, and Plato no doubt learned from him the doctrines of that philosopher.

It is improbable that he allowed himself to remain unacquainted with the disputations of the Sophists, many of whom were his own contemporaries. He probably read the book of Anaxagoras, which was easily obtainable in Athens at the time. But on all these points we have no certain information. What we do know is that the decisive event in his youth, and indeed in his life, was his a.s.sociation with Socrates.

For the last eight years of the life of Socrates, Plato was his friend and his faithful disciple. The teaching and personality of the master const.i.tuted the supreme intellectual impulse of his life, and the inspiration of his entire thought. And the devotion and esteem which he felt for Socrates, so far from waning as the years went by, seem, on the contrary, to have grown continually stronger. For it is precisely in the latest dialogues of his long life that some of the most charming and admiring portraits of Socrates are to be found.

Socrates became for him the pattern and exemplar of the true philosopher.

After the death of Socrates a second period opens in the life of Plato, the period of his travels. He migrated first to Megara, where his friend and fellow-disciple Euclid was then founding the Megaric school. The Megaric philosophy was a combination of the thought of Socrates with that of the Eleatics. And it was no doubt here, at {167} Megara, under the influence of Euclid, that Plato formed his deeper acquaintance with the teaching of Parmenides, which exercised an all-important influence upon his own philosophy. From Megara he travelled to Cyrene, Egypt, Italy, and Sicily. In Italy he came in contact with the Pythagoreans. And to the effects of this journey may be attributed the strong Pythagorean elements which permeate his thought.

In Sicily he attended the court of Dionysius the Elder, tyrant of Syracuse. But here his conduct seems to have given grave offence.

Dionysius was so angered by his moralizings and philosophical diatribes that he put Plato up to auction in the slave market. Plato narrowly escaped the fate of slavery, but was ransomed by Anniceris, the Cyrenaic. He then returned to Athens, his travels having occupied a period of about ten years.

With the return of Plato to Athens we enter upon the third and last period of his life. With the exception of two journeys to be mentioned shortly, he never again left Athens. He now appeared for the first time as a professional teacher and philosopher. He chose for the scene of his activities a gymnasium, called the Academy. Here he gradually collected round him a circle of pupils and disciples. For the rest of his life, a period of about forty years, he occupied himself in literary activity, and in the management of the school which he had founded. His manner of life was in strong contrast to that of Socrates. Only in one respect did he resemble his master. He took no fees for his teaching. Otherwise the lives of the two great men bear no resemblance to each other. Socrates had gone out into the highways and byways in search of wisdom. He had wrangled in {168} the market-place with all comers. Plato withdrew himself into the seclusion of a school, protected from the hubbub of the world by a ring of faithful disciples. It was not to be expected that a man of Plato's refinement, culture, and aristocratic feelings, should appreciate, as Socrates, the man of the people, had done, the rough-and-tumble life of the Athenian market-place. Nor was it desirable for the advancement of philosophy that it should be so. The Socratic philosophy had suffered from the Socratic manner of life. It was unmethodical and inchoate. Systematic thought is not born of disputes at the street corner. For the development of a great world-system, such as that of Plato, laborious study and quiet seclusion were essential.

This period of Plato's masters.h.i.+p was broken only by two journeys to Sicily, both undertaken with political objects. Plato knew well that the perfect State, as depicted in his "Republic," was not capable of realization in the Greece of his own time. Nevertheless, he took his political philosophy very seriously. Though the perfect republic was an unattainable ideal, yet, he thought, any real reform of the State must at least proceed in the direction of that ideal. One of the essential principles of the "Republic" was that the rulers must also be philosophers. Not till philosopher and ruler were combined in one and the same person could the State be governed upon true principles.

Now, in the year 368 B.C., Dionysius the Elder died, and Dionysius the younger became tyrant of Syracuse. Dionysius despatched an invitation to Plato to attend his court and give him the benefit of his advice.

Here was an opportunity to experiment. Plato could train and educate a {169} philosopher-king. He accepted the invitation. But the expedition ended disastrously. Dionysius received him with enthusiasm, and interested himself in the philosophical discourses of his teacher. But he was young, impetuous, hot-headed, and without genuine philosophic bent. His first interest gave place to weariness and irritation. Plato left Syracuse a disappointed man; and returned to Athens.

Nevertheless, after the lapse of a few years, Dionysius again invited him to Syracuse, and again he accepted the invitation. But the second journey ended in disaster like the first, and Plato was even in danger of his life, but was rescued by the intervention of the Pythagoreans.

He returned to Athens in his seventieth year, and lived till his death in the seclusion of his school, never again attempting to intervene in practical politics.

For more than another decade he dwelt and taught in Athens. His life was serene, quiet, and happy. He died peacefully at the age of eighty-two.

Plato's writings take the form of dialogues. In the majority of these, the chief part is taken by Socrates, into whose mouth Plato puts the exposition of his own philosophy. In a few, as for example the "Parmenides," other speakers enunciate the Platonic teaching, but even in these Socrates always plays an important _role_. Plato was not only a philosopher, but a consummate literary artist. The dialogues are genuinely dramatic, enlivened by incident, humour, and life-like characterization. Not only is the portrait of Socrates drawn with loving affection, but even the minor characters are flesh and blood.

A most important element of Plato's style is his use of myths. He does not always explain his meaning in {170} the form of direct scientific exposition. He frequently teaches by allegories, fables, and stories, all of which may be included under the one general appellation of Platonic myths. These are often of great literary beauty, but in spite of this they involve grave disadvantages. Plato slips so easily from scientific exposition into myth, that it is often no easy matter to decide whether his statements are meant literally or allegorically.

Moreover, the myths usually signify a defect in his thought itself.

The fact is that the combination of poet and philosopher in one man is an exceedingly dangerous combination. I have explained before that the object of philosophy is, not merely to feel the truth, as the poet and mystic feel it, but intellectually to comprehend it, not merely to give us a series of pictures and metaphors, but a reasoned explanation of things upon scientific principles. When a man, who is at once a poet and a philosopher, cannot rationally explain a thing, it is a terrible temptation to him to subst.i.tute poetic metaphors for the explanation which is lacking. We saw, for example, that the writers of the Upanishads, who believed that the whole world issues forth from the one, absolute, imperishable, being, which they called Brahman, being unable to explain why the One thus differentiates itself into the many, took refuge in metaphors. As the sparks from the substantial fire, so, they say, do all finite beings issue forth from the One. But this explains nothing, and the aim of the philosopher is not thus vaguely to feel, but rationally to understand. Now this is not merely my view of the functions of philosophy. It is emphatically Plato's own view. In fact Plato was the originator of it. He is perpetually insisting that {171} nothing save full rational comprehension deserves the names of knowledge and philosophy. No writer has ever used such contemptuous language as Plato used of the mere mystic and poet, who says wise and beautiful things, without in the least understanding why they are wise and beautiful. No man has formed such a low estimate of the functions of the poet and mystic. Plato is, in theory at least, the prince of rationalists and intellectualists. In practice, however, he must be convicted of the very fault he so severely censured in others. This, in fact, is the explanation of most of the Platonic myths. Wherever Plato is unable to explain anything, he covers up the gap in his system with a myth. This is particularly noticeable, for example, in the "Timaeus." Plato having, in other dialogues, developed his theory of the nature of the ultimate reality, arrives, in the "Timaeus," at the problem how the actual world is to be explained from that ultimate reality. At this point, as we shall see, Plato's system breaks down. His account of the absolute reality is defective, and in consequence, it affords no principle whereby the actual universe can be explained. In the "Timaeus," therefore, instead of a reasoned explanation, he gives us a series of wholly fanciful myths about the origin of the world. Wherever we find myths in Plato's dialogues, we may suspect that we have arrived at one of the weak points of the system.

If we are to study Plato intelligently, it is essential that we should cease to regard the dialogues as if they were all produced _en bloc_ from a single phase of their author's mind. His literary activity extended over a period of not less than fifty years. During that time, he did not stand still. His thought, and his mode of {172} expression, were constantly developing. If we are to understand Plato, we must obtain some clue to enable us to trace this development. And this means that we must know something of the order in which the dialogues were written. Unfortunately, however, they have not come down to us dated and numbered. It is a matter of scholars.h.i.+p and criticism to deduce the period at which any dialogue was written from internal evidences. Many minor points are still undecided, as well as a few questions of importance, such as the date of the "Phaedrus," [Footnote 11] which some critics place quite early and some very late in Plato's life. Neglecting these points, however, we may say in general that unanimity has been reached, and that we now know enough to be able to trace the main lines of development.

[Footnote 11: The same remark applies to the "Symposium," the "Republic," and the "Theaetetus."]

The dialogues fall into three main groups, which correspond roughly to the three periods of Plato's life. Those of the earliest group were written about the time of the death of Socrates, and before the author's journey to Megara. Some of them may have been written before the death of Socrates. This group includes the "Hippias Minor," the "Lysis," the "Charmides," the "Laches," the "Euthyphro," the "Apology," the "Crito," and the "Protagoras." The "Protagoras" is the longest, the most complex in thought, and the most developed. It is probably the latest, and forms the bridge to the second group.

All these early dialogues are short and simple, and are still, as regards their thought, entirely under the influence of Socrates. Plato has not as yet developed {173} any philosophy of his own. He propounds the philosophy of Socrates almost unaltered. Even so, however, he is no mere plagiarist. There are throughout these dialogues evidences of freshness and originality, but these qualities exhibit themselves rather in the literary form than in the philosophical substance. We find here all the familiar Socratic propositions, that virtue is knowledge, is one, is teachable; that all men seek the good, but that men differ as to what the good is; that a man who does wrong deliberately is better than a man who does it unintentionally; and so on. Moreover, just as Socrates had occupied himself in attempting to fix the concepts of the virtues, asking "what is prudence?", "what is temperance?", and the like, so in many of these dialogues Plato pursues similar inquiries. The "Lysis" discusses the concept of friends.h.i.+p, the "Charmides" of temperance, the "Laches" of bravery. On the whole, the philosophical substance of these early writings is thin and meagre. There is a preponderance of incident and much biographical detail regarding Socrates. There is more art than matter.

Consequently, from a purely literary point of view, these are among the most charming of Plato's dialogues, and many of them, such as the "Apology" and the "Crito," are especially popular with those who care for Plato rather as an artist than as a philosopher.

The second group of dialogues is generally connected with the period of Plato's travels. In addition to the influence of Socrates, we have now the influence of the Eleatics, which naturally connects these dialogues with the period of the philosopher's sojourn at Megara. But it is in these dialogues, too, that Plato for the first time {174} develops his own special philosophical thesis. This is in fact his great constructive period. The central and governing principle of his philosophy is the theory of Ideas. All else hinges on this, and is dominated by this. In a sense, his whole philosophy is nothing but the theory of Ideas and what depends upon it. It is in this second period that the theory of Ideas is founded and developed, and its relations.h.i.+p to the Eleatic philosophy of Being discussed. We have here the spectacle of Plato's most original thoughts in the pangs of childbirth. He is now at grips with the central problems of philosophy. He is intent upon the thought itself, and cares little for the ornaments of style. He is struggling to find expression for ideas newly-formed in his mind, of which he is not yet completely master, and which he cannot manipulate with ease. Consequently, the literary graces of the first period recede into the background. There is little incident, and no humour. There is nothing but close reasoning, hard and laborious discussion.

The twin dialogues, "Gorgias" and "Theaetetus" are probably the earliest of this group. They result in nothing very definite, and are chiefly negative in character. Plato is here engaged merely in a preparatory clearing of the ground. The "Gorgias" discusses and refutes the Sophistic identification of virtue and pleasure, and attempts to show, as against it, that the good must be something objectively existent, and independent of the pleasure of the individual. The "Theaetetus," similarly, shows that truth is not, as the Sophists thought, merely the subjective impression of the individual, but is something objectively true in itself. The other {175} dialogues of the group are the "Sophist," the "Statesman," and the "Parmenides." The "Sophist" discusses Being and not-being, and their relations.h.i.+p to the theory of Ideas. The "Parmenides" inquires whether the absolute reality is to be regarded, in the manner of the Eleatics, as an abstract One. It gives us, therefore, Plato's conception of the relation of his own philosophy to Eleaticism.

The dialogues of the third group are the work of Plato's maturity. He has now completely mastered his thought, and turns it with ease in all directions. Hence the style returns to the lucidity and purity of the first period. If the first period was marked chiefly by literary grace, the second by depth of thought, the third period combines both.

The perfect substance is now moulded in the perfect form. But a peculiarity of all the dialogues of this period is that they take it for granted that the theory of Ideas is already established and familiar to the reader. They proceed to apply it to all departments of thought. The second period was concerned with the formulation and proof of the theory of Ideas, the third period undertakes its systematic application. Thus the "Symposium," which has for its subject the metaphysic of love, attempts to connect man's feeling for beauty with the intellectual knowledge of the Ideas. The "Philebus"

applies the theory of Ideas to the sphere of ethics, the "Timaeus" to the sphere of physics, and the "Republic" to the sphere of politics.

The "Phaedo" founds the doctrine of the immortality of the soul upon the theory of Ideas. The "Phaedrus" is probably to be grouped with the "Symposium." The beauty, grace, and lucidity of the style, and the fact that it a.s.sumes throughout that {176} the theory of Ideas is a thing established, lead us to the belief that it belongs to the period of Plato's maturity. Zeller's theory that it was written at the beginning of the second period, and is then offered to the reader as a sort of sweetmeat to induce him to enter upon the laborious task of reading the "Sophist," the "Statesman," and the "Parmenides," seems to be far-fetched and unnecessary. [Footnote 12]
