I.

In studying the growth of philosophy as an historical evolution, repetitions and anticipations must necessarily be of frequent occurrence. Ideas meet us at every step which can only be appreciated when we trace out their later developments, or only understood when we refer them back to earlier and half-forgotten modes of thought. The speculative tissue is woven out of filaments so delicate and so complicated that it is almost impossible to say where one begins and the other ends. Even conceptions which seem to have been transmitted without alteration are constantly acquiring a new value according to the connexions into which they enter or the circumstances to which they are applied. But if the method of evolution, with its two great principles of continuity and relativity, substitutes a maze of intricate lines, often returning on themselves, for the straight path along which progress was once supposed to move, we are more than compensated by the new sense of coherence and rationality where illusion and extravagance once seemed to reign supreme. It teaches us that the dreams of a great intellect may be better worth our attention than the waking perceptions of ordinary men. Combining fragments of the old order with rudimentary outlines of the new, they lay open the secret laboratory of spiritual chemistry, and help to bridge over the interval separating the most widely contrasted phases of life and thought. Moreover, when we have once accustomed ourselves to break up past systems of philosophy172 into their component elements, when we see how heterogeneous and ill-cemented were the parts of this and that proud edifice once offered as the only possible shelter against dangers threatening the very existence of civilisation—we shall be prepared for the application of a similar method to contemporary systems of equally ambitious pretensions; distinguishing that which is vital, fruitful, original, and progressive in their ideal synthesis from that which is of merely provisional and temporary value, when it is not the literary resuscitation of a dead past, visionary, retrograde, and mischievously wrong. And we shall also be reminded that the most precious ideas have only been shaped, preserved, and transmitted through association with earthy and perishable ingredients. The function of true criticism is, like Robert Browning’s Roman jeweller, to turn on them ‘the proper fiery acid’ of purifying analysis which dissolves away the inferior metal and leaves behind the gold ring whereby thought and action are inseparably and fruitfully united.

Such, as it seems to us, is the proper spirit in which we should approach the great thinker whose works are to occupy us in this and the succeeding chapter. No philosopher has ever offered so extended and vulnerable a front to hostile criticism. None has so habitually provoked reprisals by his own incessant and searching attacks on all existing professions, customs, and beliefs. It might even be maintained that none has used the weapons of controversy with more unscrupulous zeal. And it might be added that he who dwells so much on the importance of consistency has occasionally denounced and ridiculed the very principles which he elsewhere upholds as demonstrated truths. It was an easy matter for others to complete the work of destruction which he had begun. His system seems at first sight to be made up of assertions, one more outrageous than another. The ascription of an objective concrete separate reality to verbal abstractions is assuredly the most astounding paradox ever173 maintained even by a metaphysician. Yet this is the central article of Plato’s creed. That body is essentially different from extension might, one would suppose, have been sufficiently clear to a mathematician who had the advantage of coming after Leucippus and Democritus. Their identity is implicitly affirmed in the Timaeus. That the soul cannot be both created and eternal; that the doctrine of metempsychosis is incompatible with the hereditary transmission of mental qualities; that a future immortality equivalent to, and proved by the same arguments as, our antenatal existence, would be neither a terror to the guilty nor a consolation to the righteous:—are propositions implicitly denied by Plato’s psychology. Passing from theoretical to practical philosophy, it might be observed that respect for human life, respect for individual property, respect for marriage, and respect for truthfulness, are generally numbered among the strongest moral obligations, and those the observance of which most completely distinguishes civilised from savage man; while infanticide, communism, promiscuity, and the occasional employment of deliberate deceit, form part of Plato’s scheme for the redemption of mankind. We need not do more than allude to those Dialogues where the phases and symptoms of unnameable passion are delineated with matchless eloquence, and apparently with at least as much sympathy as censure. Finally, from the standpoint of modern science, it might be urged that Plato used all his powerful influence to throw back physical speculation into the theological stage; that he deliberately discredited the doctrine of mechanical causation which, for us, is the most important achievement of early Greek thought; that he expatiated on the criminal folly of those who held the heavenly bodies to be, what we now know them to be, masses of dead matter with no special divinity about them; and that he proposed to punish this and other heresies with a severity distinguishable from the fitful fanaticism of his native city only by its more disciplined and rigorous application.

174

A plain man might find it difficult to understand how such extravagances could be deliberately propounded by the greatest intellect that Athens ever produced, except on the principle, dear to mediocrity, that genius is but little removed from madness, and that philosophical genius resembles it more nearly than any other. And his surprise would become much greater on learning that the best and wisest men of all ages have looked up with reverence to Plato; that thinkers of the most opposite schools have resorted to him for instruction and stimulation; that his writings have never been more attentively studied than in our own age—an age which has witnessed the destruction of so many illusive reputations; and that the foremost of English educators has used all his influence to promote the better understanding and appreciation of Plato as a prime element in academic culture—an influence now extended far beyond the limits of his own university through that translation of the Platonic Dialogues which is too well known to need any commendation on our part, but which we may mention as one of the principal authorities used for the present study, together with the work of a German scholar, his obligations to whom Prof. Jowett has acknowledged with characteristic grace.114

As a set-off against the list of paradoxes cited from Plato, it would be easy to quote a still longer list of brilliant contributions to the cause of truth and right, to strike a balance between the two, and to show that there was a preponderance on the positive side sufficiently great to justify the favourable verdict of posterity. We believe, however, that such a method would be as misleading as it is superficial. Neither Plato nor any other thinker of the same calibre—if any other there be—should be estimated by a simple analysis of his opinions. We must go back to the underlying forces of which individual175 opinions are the resultant and the revelation. Every systematic synthesis represents certain profound intellectual tendencies, derived partly from previous philosophies, partly from the social environment, partly from the thinker’s own genius and character. Each of such tendencies may be salutary and necessary, according to the conditions under which it comes into play, and yet two or more of them may form a highly unstable and explosive compound. Nevertheless, it is in speculative combinations that they are preserved and developed with the greatest distinctness, and it is there that we must seek for them if we would understand the psychological history of our race. And this is why we began by intimating that the lines of our investigation may take us back over ground which has been already traversed, and forward into regions which cannot at present be completely surveyed.

We have this great advantage in dealing with Plato—that his philosophical writings have come down to us entire, while the thinkers who preceded him are known only through fragments and second-hand reports. Nor is the difference merely accidental. Plato was the creator of speculative literature, properly so called: he was the first and also the greatest artist that ever clothed abstract thought in language of appropriate majesty and splendour; and it is probably to their beauty of form that we owe the preservation of his writings. Rather unfortunately, however, along with the genuine works of the master, a certain number of pieces have been handed down to us under his name, of which some are almost universally admitted to be spurious, while the authenticity of others is a question on which the best scholars are still divided. In the absence of any very cogent external evidence, an immense amount of industry and learning has been expended on this subject, and the arguments employed on both sides sometimes make us doubt whether the reasoning powers of philologists are better developed than, according to Plato, were those of mathematicians in his time. The176 two extreme positions are occupied by Grote, who accepts the whole Alexandrian canon, and Krohn, who admits nothing but the Republic;115 while much more serious critics, such as Schaarschmidt, reject along with a mass of worthless compositions several Dialogues almost equal in interest and importance to those whose authenticity has never been doubted. The great historian of Greece seems to have been rather undiscriminating both in his scepticism and in his belief; and the exclusive importance which he attributed to contemporary testimony, or to what passed for such with him, may have unduly biassed his judgment in both directions. As it happens, the authority of the canon is much weaker than Grote imagined; but even granting his extreme contention, our view of Plato’s philosophy would not be seriously affected by it, for the pieces which are rejected by all other critics have no speculative importance whatever. The case would be far different were we to agree with those who impugn the genuineness of the Parmenides, the Sophist, the Statesman, the Philêbus, and the Laws; for these compositions mark a new departure in Platonism amounting to a complete transformation of its fundamental principles, which indeed is one of the reasons why their authenticity has been denied. Apart, however, from the numerous evidences of Platonic authorship furnished by the Dialogues themselves, as well as by the indirect references to them in Aristotle’s writings, it seems utterly incredible that a thinker scarcely, if at all, inferior to the master himself—as the supposed imitator must assuredly have been—should have consented to let his reasonings pass current under a false name, and that, too, the name of one whose teaching he in some respects controverted; while there is a further difficulty in assuming that his existence could pass unnoticed at a period marked by intense literary and philosophical activity. Readers who177 wish for fuller information on the subject will find in Zeller’s pages a careful and lucid digest of the whole controversy leading to a moderately conservative conclusion. Others will doubtless be content to accept Prof. Jowett’s verdict, that ‘on the whole not a sixteenth part of the writings which pass under the name of Plato, if we exclude the works rejected by the ancients themselves, can be fairly doubted by those who are willing to allow that a considerable change and growth may have taken place in his philosophy.’116 To which we may add that the Platonic dialogues, whether the work of one or more hands, and however widely differing among themselves, together represent a single phase of thought, and are appropriately studied as a connected series.

We have assumed in our last remark that it is possible to discover some sort of chronological order in the Platonic Dialogues, and to trace a certain progressive modification in the general tenor of their teaching from first to last. But here also the positive evidence is very scanty, and a variety of conflicting theories have been propounded by eminent scholars. Where so much is left to conjecture, the best that can be said for any hypothesis is that it explains the facts according to known laws of thought. It will be for the reader to judge whether our own attempt to trace the gradual evolution of Plato’s system satisfies this condition. In making it we shall take as a basis the arrangement adopted by Prof. Jowett, with some reservations hereafter to be specified.

Before entering on our task, one more difficulty remains to be noticed. Plato, although the greatest master of prose composition that ever lived, and for his time a remarkably voluminous author, cherished a strong dislike for books, and even affected to regret that the art of writing had ever been invented. A man, he said, might amuse himself by putting down his ideas on paper, and might even find written178 memoranda useful for private reference, but the only instruction worth speaking of was conveyed by oral communication, which made it possible for objections unforeseen by the teacher to be freely urged and answered.117 Such had been the method of Socrates, and such was doubtless the practice of Plato himself whenever it was possible for him to set forth his philosophy by word of mouth. It has been supposed, for this reason, that the great writer did not take his own books in earnest, and wished them to be regarded as no more than the elegant recreations of a leisure hour, while his deeper and more serious thoughts were reserved for lectures and conversations, of which, beyond a few allusions in Aristotle, every record has perished. That such, however, was not the case, may be easily shown. In the first place it is evident, from the extreme pains taken by Plato to throw his philosophical expositions into conversational form, that he did not despair of providing a literary substitute for spoken dialogue. Secondly, it is a strong confirmation of this theory that Aristotle, a personal friend and pupil of Plato during many years, should so frequently refer to the Dialogues as authoritative evidences of his master’s opinions on the most important topics. And, lastly, if it can be shown that the documents in question do actually embody a comprehensive and connected view of life and of the world, we shall feel satisfied that the oral teaching of Plato, had it been preserved, would not modify in any material degree the impression conveyed by his written compositions.
II.

There is a story that Plato used to thank the gods, in what some might consider a rather Pharisaic spirit, for having made him a human being instead of a brute, a man instead of a woman, and a Greek instead of a barbarian; but more than179 anything else for having permitted him to be born in the time of Socrates. It will be observed that all these blessings tended in one direction, the complete supremacy in his character of reason over impulse and sense. To assert, extend, and organise that supremacy was the object of his whole life. Such, indeed, had been the object of all his predecessors, and such, stated generally, has been always and everywhere the object of philosophy; but none had pursued it so consciously before, and none has proclaimed it so enthusiastically since then. Now, although Plato could not have done this without a far wider range of knowledge and experience than Socrates had possessed, it was only by virtue of the Socratic method that his other gifts and acquisitions could be turned to complete account; while, conversely, it was only when brought to bear upon these new materials that the full power of the method itself could be revealed. To be continually asking and answering questions; to elicit information from everybody on every subject worth knowing; and to elaborate the resulting mass of intellectual material into the most convenient form for practical application or for further transmission, was the secret of true wisdom with the sage of the market-place and the workshop. But the process of dialectic investigation as an end in itself, the intense personal interest of conversation with living men and women of all classes, the impatience for immediate and visible results, had gradually induced Socrates to restrict within far too narrow limits the sources whence his ideas were derived and the purposes to which they were applied. And the dialectic method itself could not but be checked in its internal development by this want of breadth and variety in the topics submitted to its grasp. Therefore the death of Socrates, however lamentable in its occasion, was an unmixed benefit to the cause for which he laboured, by arresting (as we must suppose it to have arrested) the popular and indiscriminate employment of his cross-examining method,180 liberating his ablest disciple from the ascendency of a revered master, and inducing him to reconsider the whole question of human knowledge and action from a remoter point of view. For, be it observed that Plato did not begin where Socrates had left off; he went back to the germinal point of the whole system, and proceeded to reconstruct it on new lines of his own. The loss of those whom we love habitually leads our thoughts back to the time of our first acquaintance with them, or, if these are ascertainable, to the circumstances of their early life. In this manner Plato seems to have been at first occupied exclusively with the starting-point of his friend’s philosophy, and we know, from the narrative given in the Apologia, under what form he came to conceive it. We have attempted to show that the account alluded to cannot be entirely historical. Nevertheless it seems sufficiently clear that Socrates began with a conviction of his own ignorance, and that his efforts to improve others were prefaced by the extraction of a similar confession of ignorance on their part. It is also certain that through life he regarded the causes of physical phenomena as placed beyond the reach of human reason and reserved by the gods for their own exclusive cognisance, pointing, by way of proof, to the notorious differences of opinion prevalent among those who had meddled with such matters. Thus, his scepticism worked in two directions, but on the one side it was only provisional and on the other it was only partial. Plato began by combining the two. He maintained that human nescience is universal and necessary; that the gods had reserved all knowledge for themselves; and that the only wisdom left for men is a consciousness of their absolute ignorance. The Socratic starting-point gave the centre of his agnostic circle; the Socratic theology gave the distance at which it was described. Here we have to note two things—first, the breadth of generalisation which distinguishes the disciple from the master; and, secondly, the symptoms of a strong181 religious reaction against Greek humanism. Even before the end of the Peloponnesian War, evidence of this reaction had appeared, and the Bacchae of Euripides bears striking testimony to its gloomy and fanatical character. The last agony of Athens, the collapse of her power, and the subsequent period of oligarchic terrorism, must have given a stimulus to superstition like that which quite recently afflicted France with an epidemic of apparitions and pilgrimages almost too childish for belief. Plato followed the general movement, although on a much higher plane. While looking down with undisguised contempt on the immoral idolatry of his countrymen, he was equally opposed to the irreligion of the New Learning, and, had an opportunity been given him, he would, like the Reformers of the sixteenth century, have put down both with impartial severity. Nor was this the only analogy between his position and that of a Luther or a Calvin. Like them, and indeed like all great religious teachers, he exalted the Creator by enlarging on the nothingness of the creature; just as Christianity exhibits the holiness of God in contrast and correlation with the sinfulness of unregenerate hearts; just as to Pindar man’s life seemed but the fleeting shadow in a dream when compared with the beauty and strength and immortality of the Olympian divinities; so also did Plato deepen the gloom of human ignorance that he might bring out in dazzling relief the fulness of that knowledge which he had been taught to prize as a supreme ideal, but which, for that very reason, seemed proper to the highest existences alone. And we shall presently see how Plato also discovered a principle in man by virtue of which he could claim kindred with the supernatural, and elaborated a scheme of intellectual mediation by which the fallen spirit could be regenerated and made a partaker in the kingdom of speculative truth.

Yet if Plato’s theology, from its predominantly rational character, seemed to neglect some feelings which were better182 satisfied by the earlier or the later faiths of mankind, we cannot say that it really excluded them. The unfading strength of the old gods was comprehended in the self-existence of absolute ideas, and moral goodness was only a particular application of reason to the conduct of life. An emotional or imaginative element was also contributed by the theory that every faculty exercised without a reasoned consciousness of its processes and aims was due to some saving grace and inspiration from a superhuman power. It was thus, according to Plato, that poets and artists were able to produce works of which they were not able to render an intelligent account; and it was thus that society continued to hold together with such an exceedingly small amount of wisdom and virtue. Here, however, we have to observe a marked difference between the religious teachers pure and simple, and the Greek philosopher who was a dialectician even more than he was a divine. For Plato held that providential government was merely provisional; that the inspired prophet stood on a distinctly lower level than the critical, self-conscious thinker; that ratiocination and not poetry was the highest function of mind; and that action should be reorganised in accordance with demonstrably certain principles.118

This search after a scientific basis for conduct was quite in the spirit of Socrates, but Plato seems to have set very little value on his master’s positive contributions to the systematisation of life. We have seen that the Apologia is purely sceptical in its tendency; and we find a whole group of Dialogues, probably the earliest of Plato’s compositions, marked by the same negative, inconclusive tone. These are commonly spoken of as Socratic, and so no doubt they are in reference to the subjects discussed; but they would be more accurately described as an attempt to turn the Socratic method against its first originator. We know from another source that tem183perance, fortitude, and piety were the chief virtues inculcated and practised by Socrates; while friendship, if not strictly speaking a virtue, was equally with them one of his prime interests in life. It is clear that he considered them the most appropriate and remunerative subjects of philosophical discussion; that he could define their nature to his own satisfaction; and that he had, in fact, defined them as so many varieties of wisdom. Now, Plato has devoted a separate Dialogue to each of the conceptions in question,119 and in each instance he represents Socrates, who is the principal spokesman, as professedly ignorant of the whole subject under discussion, offering no definition of his own (or at least none that he will stand by), but asking his interlocutors for theirs, and pulling it to pieces when it is given. We do, indeed, find a tendency to resolve the virtues into knowledge, and, so far, either to identify them with one another, or to carry them up into the unity of a higher idea. To this extent Plato follows in the footsteps of his master, but a result which had completely satisfied Socrates became the starting-point of a new investigation with his successor. If virtue is knowledge, it must be knowledge of what we most desire—of the good. Thus the original difficulty returns under another form, or rather we have merely restated it in different terms. For, to ask what is temperance or fortitude, is equivalent to asking what is its use. And this was so obvious to Socrates, that, apparently, he never thought of distinguishing between the two questions. But no sooner were they distinguished than his reduction of all morality to a single principle was shown to be illusive. For each specific virtue had been substituted the knowledge of a specific utility, and that was all. Unless the highest good were one, the means by which it was sought could not converge to a single point; nor, according to the new ideas, could their mastery come under the jurisdiction of a single art.

184

We may also suspect that Plato was dissatisfied not only with the positive results obtained by Socrates, but also with the Socratic method of constructing general definitions. To rise from the part to the whole, from particular instances to general notions, was a popular rather than a scientific process; and sometimes it only amounted to taking the current explanations and modifying them to suit the exigencies of ordinary experience. The resulting definitions could never be more than tentative, and a skilful dialectician could always upset them by producing an unlooked-for exception, or by discovering an ambiguity in the terms by which they were conveyed.

Before ascertaining in what direction Plato sought for an outlet from these accumulated difficulties, we have to glance at a Dialogue belonging apparently to his earliest compositions, but in one respect occupying a position apart from the rest. The Crito tells us for what reasons Socrates refused to escape from the fate which awaited him in prison, as, with the assistance of generous friends, he might easily have done. The aged philosopher considered that by adopting such a course he would be setting the Athenian laws at defiance, and doing what in him lay to destroy their validity. Now, we know that the historical Socrates held justice to consist in obedience to the law of the land; and here for once we find Plato agreeing with him on a definite and positive issue. Such a sudden and singular abandonment of the sceptical attitude merits our attention. It might, indeed, be said that Plato’s inconsistencies defy all attempts at reconciliation, and that in this instance the desire to set his maligned friend in a favourable light triumphed over the claims of an impracticable logic. We think, however, that a deeper and truer solution can be found. If the Crito inculcates obedience to the laws as a binding obligation, it is not for the reasons which, according to Xenophon, were adduced by the real Socrates in his dispute with the Sophist Hippias; general utility and private interest were the sole grounds appealed to then. Plato, on185 the other hand, ignores all such external considerations. True to his usual method, he reduces the legal conscience to a purely dialectical process. Just as in an argument the disputants are, or ought to be, bound by their own admissions, so also the citizen is bound by a tacit compact to fulfil the laws whose protection he has enjoyed and of whose claims his protracted residence is an acknowledgment. Here there is no need of a transcendent foundation for morality, as none but logical considerations come into play. And it also deserves to be noticed that, where this very idea of an obligation based on acceptance of services had been employed by Socrates, it was discarded by Plato. In the Euthyphro, a Dialogue devoted to the discussion of piety, the theory that religion rests on an exchange of good offices between gods and men is mentioned only to be scornfully rejected. Equally remarkable, and equally in advance of the Socratic standpoint, is a principle enunciated in the Crito, that retaliation is wrong, and that evil should never be returned for evil.120 And both are distinct anticipations of the earliest Christian teaching, though both are implicitly contradicted by the so-called religious services celebrated in Christian churches and by the doctrine of a divine retribution which is only not retaliatory because it is infinitely in excess of the provocation received.

If the earliest of Plato’s enquiries, while they deal with the same subjects and are conducted on the same method as those cultivated by Socrates, evince a breadth of view surpassing anything recorded of him by Xenophon, they also exhibit traces of an influence disconnected with and inferior in value to his. On more than one occasion121 Plato reasons, or rather quibbles, in a style which he has elsewhere held up to ridicule as characteristic of the Sophists, with such success that the name of sophistry has clung to it ever since.186 Indeed, some of the verbal fallacies employed are so transparent that we can hardly suppose them to be unintentional, and we are forced to conclude that the young despiser of human wisdom was resolved to maintain his thesis with any weapons, good or bad, which came to hand. And it seems much more likely that he learned the eristic art from Protagoras or from his disciples than from Socrates. Plato spent a large part of his life in opposing the Sophists—that is to say, the paid professors of wisdom and virtue; but in spite of, or rather perhaps because of, this very opposition, he was profoundly affected by their teaching and example. It is quite conceivable, although we do not find it stated as a fact, that he resorted to them for instruction when a young man, and before coming under the influence of Socrates, an event which did not take place until he was twenty years old; or he may have been directed to them by Socrates himself. With all its originality, his style bears traces of a rhetorical training in the more elaborate passages, and the Sophists were the only teachers of rhetoric then to be found. His habit of clothing philosophical lessons in the form of a myth seems also to have been borrowed from them. It would, therefore, not be surprising that he should cultivate their argumentative legerdemain side by side with the more strict and severe discipline of Socratic dialectics.

Plato does, no doubt, make it a charge against the Sophists that their doctrines are not only false and immoral, but that they are put together without any regard for logical coherence. It would seem, however, that this style of attack belongs rather to the later and constructive than to the earlier and receptive period of his intellectual development. The original cause of his antagonism to the professional teachers seems to have been their general pretensions to knowledge, which, from the standpoint of universal scepticism, were, of course, utterly illusive; together with a feeling of aristocratic contempt for a calling in which considerations of187 pecuniary interest were involved, heightened in this instance by a conviction that the buyer received nothing better than a sham article in exchange for his money. Here, again, a parallel suggests itself with the first preaching of the Gospel. The attitude of Christ towards the scribes and Pharisees, as also that of St. Paul towards Simon Magus, will help us to understand how Plato, in another order of spiritual teaching, must have regarded the hypocrisy of wisdom, the intrusion of fraudulent traders into the temple of Delphic inspiration, and the sale of a priceless blessing whose unlimited diffusion should have been its own and only reward.

Yet throughout the philosophy of Plato we meet with a tendency to ambiguous shiftings and reversions of which, here also, due account must be taken. That curious blending of love and hate which forms the subject of a mystical lyric in Mr. Browning’s Pippa Passes, is not without its counterpart in purely rationalistic discussion. If Plato used the Socratic method to dissolve away much that was untrue, because incomplete, in Socratism, he used it also to absorb much that was deserving of development in Sophisticism. If, in one sense, the latter was a direct reversal of his master’s teaching, in another it served as a sort of intermediary between that teaching and the unenlightened consciousness of mankind. The shadow should not be confounded with the substance, but it might show by contiguity, by resemblance, and by contrast where the solid reality lay, what were its outlines, and how its characteristic lights might best be viewed.

Such is the mild and conciliatory mode of treatment at first adopted by Plato in dealing with the principal representative of the Sophists—Protagoras. In the Dialogue which bears his name the famous humanist is presented to us as a professor of popular unsystematised morality, proving by a variety of practical arguments and ingenious illustrations that virtue can be taught, and that the preservation of social order depends upon the possibility of teaching it; but unwilling to188 go along with the reasonings by which Socrates shows the applicability of rigorously scientific principles to conduct. Plato has here taken up one side of the Socratic ethics, and developed it into a complete and self-consistent theory. The doctrine inculcated is that form of utilitarianism to which Mr. Sidgwick has given the name of egoistic hedonism. We are brought to admit that virtue is one because the various virtues reduce themselves in the last analysis to prudence. It is assumed that happiness, in the sense of pleasure and the absence of pain, is the sole end of life. Duty is identified with interest. Morality is a calculus for computing quantities of pleasure and pain, and all virtuous action is a means for securing a maximum of the one together with a minimum of the other. Ethical science is constituted; it can be taught like mathematics; and so far the Sophists are right, but they have arrived at the truth by a purely empirical process; while Socrates, who professes to know nothing, by simply following the dialectic impulse strikes out a generalisation which at once confirms and explains their position; yet from self-sufficiency or prejudice they refuse to agree with him in taking their stand on its only logical foundation.

That Plato put forward the ethical theory of the Protagoras in perfect good faith cannot, we think, be doubted; although in other writings he has repudiated hedonism with contemptuous aversion; and it seems equally evident that this was his earliest contribution to positive thought. Of all his theories it is the simplest and most Socratic; for Socrates, in endeavouring to reclaim the foolish or vicious, often spoke as if self-interest was the paramount principle of human nature; although, had his assumption been formulated as an abstract proposition, he too might have shrunk from it with something of the uneasiness attributed to Protagoras. And from internal evidence of another description we have reason to think that the Dialogue in question is a comparatively juvenile production, remembering always that the period of youth was much more189 protracted among the Greeks than among ourselves. One almost seems to recognise the hand of a boy just out of college, who delights in drawing caricatures of his teachers; and who, while he looks down on classical scholarship in comparison with more living and practical topics, is not sorry to show that he can discuss a difficult passage from Simonides better than the professors themselves.
III.

Our survey of Plato’s first period is now complete; and we have to enter on the far more arduous task of tracing out the circumstances, impulses, and ideas by which all the scattered materials of Greek life, Greek art, and Greek thought were shaped into a new system and stamped with the impress of an imperishable genius. At the threshold of this second period the personality of Plato himself emerges into greater distinctness, and we have to consider what part it played in an evolution where universal tendencies and individual leanings were inseparably combined.

Plato was born in the year 429, or according to some accounts 427, and died 347 B.C. Few incidents in his biography can be fixed with any certainty; but for our purpose the most general facts are also the most interesting, and about these we have tolerably trustworthy information. His family was one of the noblest in Athens, being connected on the father’s side with Codrus, and on the mother’s with Solon; while two of his kinsmen, Critias and Charmides, were among the chiefs of the oligarchic party. It is uncertain whether he inherited any considerable property, nor is the question one of much importance. It seems clear that he enjoyed the best education Athens could afford, and that through life he possessed a competence sufficient to relieve him from the cares of material existence. Possibly the preference which he expressed, when far advanced in life, for moderate health and190 wealth arose from having experienced those advantages himself. If the busts which bear his name are to be trusted, he was remarkably beautiful, and, like some other philosophers, very careful of his personal appearance. Perhaps some reminiscences of the admiration bestowed on himself may be mingled with those pictures of youthful loveliness and of its exciting effect on the imaginations of older men which give such grace and animation to his earliest dialogues. We know not whether as lover or beloved he passed unscathed through the storms of passion which he has so powerfully described, nor whether his apparently intimate acquaintance with them is due to divination or to regretful experience. We may pass by in silence whatever is related on this subject, with the certainty that, whether true or not, scandalous stories could not fail to be circulated about him.

It was natural that one who united a great intellect to a glowing temperament should turn his thoughts to poetry. Plato wrote a quantity of verses—verse-making had become fashionable just then—but wisely committed them to the flames on making the acquaintance of Socrates. It may well be doubted whether the author of the Phaedrus and the Symposium would ever have attained eminence in metrical composition, even had he lived in an age far more favourable to poetic inspiration than that which came after the flowering time of Attic art. It seems as if Plato, with all his fervour, fancy, and dramatic skill, lacked the most essential quality of a singer; his finest passages are on a level with the highest poetry, and yet they are separated from it by a chasm more easily felt than described. Aristotle, whom we think of as hard and dry and cold, sometimes comes much nearer to the true lyric cry. And, as if to mark out Plato’s style still more distinctly from every other, it is also deficient in oratorical power. The philosopher evidently thought that he could beat the rhetoricians on their own ground; if the Menexenus be genuine, he tried to do so and failed; and even without its191 testimony we are entitled to say as much on the strength of shorter attempts. We must even take leave to doubt whether dialogue, properly so called, was Plato’s forte. Where one speaker is placed at such a height above the others as Socrates, or the Eleatic Stranger, or the Athenian in the Laws, there cannot be any real conversation. The other interlocutors are good listeners, and serve to break the monotony of a continuous exposition by their expressions of assent or even by their occasional inability to follow the argument, but give no real help or stimulus. And when allowed to offer an opinion of their own, they, too, lapse into a monologue, addressed, as our silent trains of thought habitually are, to an imaginary auditor whose sympathy and support are necessary but are also secure. Yet if Plato’s style is neither exactly poetical, nor oratorical, nor conversational, it has affinities with each of these three varieties; it represents the common root from which they spring, and brings us, better than any other species of composition, into immediate contact with the mind of the writer. The Platonic Socrates has eyes like those of a portrait which follow us wherever we turn, and through which we can read his inmost soul, which is no other than the universal reason of humanity in the delighted surprise of its first awakening to self-conscious activity. The poet thinks and feels for us; the orator makes our thoughts and feelings his own, and then restores them to us in a concentrated form, ‘receiving in vapour what he gives back in a flood.’ Plato removes every obstacle to the free development of our faculties; he teaches us by his own example how to think and to feel for ourselves. If Socrates personified philosophy, Plato has reproduced the personification in artistic form with such masterly effect that its influence has been extended through all ages and over the whole civilised world. This portrait stands as an intermediary between its original and the far-reaching effects indirectly due to his dialectic inspiration, like that universal soul which Plato himself has placed between192 the supreme artificer and the material world, that it might bring the fleeting contents of space and time into harmony with uncreated and everlasting ideas.

To paint Socrates at his highest and his best, it was necessary to break through the narrow limits of his historic individuality, and to show how, had they been presented to him, he would have dealt with problems outside the experience of a home-staying Athenian citizen. The founder of idealism—that is to say, the realisation of reason, the systematic application of thought to life—had succeeded in his task because he had embodied the noblest elements of the Athenian Dêmos, orderliness, patriotism, self-control, and publicity of debate, together with a receptive intelligence for improvements effected in other states. But, just as the impulse which enabled those qualities to tell decisively on Greek history at a moment of inestimable importance came from the Athenian aristocra............
