the rest of the Republic they are partly Greek and partly ideal, beginning with the ordinary curriculum of the Greek youth, and extending to after-life. Plato is the first writer who distinctly says that education is to comprehend the whole of life, and to be a preparation for another in which education begins again. This is the continuous thread which runs through the Republic, and which more than any other of his ideas admits of an application to modern life.
He has long given up the notion that virtue cannot be taught; and he is disposed to modify the thesis of the Protagoras, that the virtues are one and not many. He is not unwilling to admit the sensible world into his scheme of truth. Nor does he assert in the Republic the involuntariness of vice, which is maintained by him in the Timaeus, Sophist, and Laws (Protag., Apol., Gorg.). Nor do the so-called Platonic ideas recovered from a former state of existence affect his theory of mental improvement. Still we observe in him the remains of the old Socratic doctrine, that true knowledge must be elicited from within, and is to be sought for in ideas, not in particulars of sense. Education, as he says, will implant a principle of intelligence which is better than ten thousand eyes. The paradox that the virtues are one, and the kindred notion that all virtue is knowledge, are not entirely renounced; the first is seen in the supremacy given to justice over the rest; the second in the tendency to absorb the moral virtues in the intellectual, and to centre all goodness in the contemplation of the idea of good. The world of sense is still depreciated and identified with opinion, though admitted to be a shadow of the true. In the Republic he is evidently impressed with the conviction that vice arises chiefly from ignorance and may be cured by education; the multitude are hardly to be deemed responsible for what they do. A faint allusion to the doctrine of reminiscence occurs in the Tenth Book; but Plato’s views of education have no more real connection with a previous state of existence than our own; he only proposes to elicit from the mind that which is there already. Education is represented by him, not as the filling of a vessel, but as the turning the eye of the soul towards the light.
He treats first of music or literature, which he divides into true and false, and then goes on to gymnastics; of infancy in the Republic he takes no notice, though in the Laws he gives sage counsels about the nursing of children and the management of the mothers, and would have an education which is even prior to birth. But in the Republic he begins with the age at which the child is capable of receiving ideas, and boldly asserts, in language which sounds paradoxical to modern ears, that he must be taught the false before he can learn the true. The modern and ancient philosophical world are not agreed about truth and falsehood; the one identifies truth almost exclusively with fact, the other with ideas. This is the difference between ourselves and Plato, which is, however, partly a difference of words. For we too should admit that a child must receive many lessons which he imperfectly understands; he must be taught some things in a figure only, some too which he can hardly be expected to believe when he grows older; but we should limit the use of fiction by the necessity of the case. Plato would draw the line differently; according to him the aim of early education is not truth as a matter of fact, but truth as a matter of principle; the child is to be taught first simple religious truths, and then simple moral truths, and insensibly to learn the lesson of good manners and good taste. He would make an entire reformation of the old mythology; like Xenophanes and Heracleitus he is sensible of the deep chasm which separates his own age from Homer and Hesiod, whom he quotes and invests with an imaginary authority, but only for his own purposes. The lusts and treacheries of the gods are to be banished; the terrors of the world below are to be dispelled; the misbehaviour of the Homeric heroes is not to be a model for youth. But there is another strain heard in Homer which may teach our youth endurance; and something may be learnt in medicine from the simple practice of the Homeric age. The principles on which religion is to be based are two only: first, that God is true; secondly, that he is good. Modern and Christian writers have often fallen short of these; they can hardly be said to have gone beyond them.
The young are to be brought up in happy surroundings, out of the way of sights or sounds which may hurt the character or vitiate the taste. They are to live in an atmosphere of health; the breeze is always to be wafting to them the impressions of truth and goodness. Could such an education be realized, or if our modern religious education could be bound up with truth and virtue and good manners and good taste, that would be the best hope of human improvement. Plato, like ourselves, is looking forward to changes in the moral and religious world, and is preparing for them. He recognizes the danger of unsettling young men’s minds by sudden changes of laws and principles, by destroying the sacredness of one set of ideas when there is nothing else to take their place. He is afraid too of the influence of the drama, on the ground that it encourages false sentiment, and therefore he would not have his children taken to the theatre; he thinks that the effect on the spectators is bad, and on the actors still worse. His idea of education is that of harmonious growth, in which are insensibly learnt the lessons of temperance and endurance, and the body and mind develope in equal proportions. The first principle which runs through all art and nature is simplicity; this also is to be the rule of human life.
The second stage of education is gymnastic, which answers to the period of muscular growth and development. The simplicity which is enforced in music is extended to gymnastic; Plato is aware that the training of the body may be inconsistent with the training of the mind, and that bodily exercise may be easily overdone. Excessive training of the body is apt to give men a headache or to render them sleepy at a lecture on philosophy, and this they attribute not to the true cause, but to the nature of the subject. Two points are noticeable in Plato’s treatment of gymnastic:—First, that the time of training is entirely separated from the time of literary education. He seems to have thought that two things of an opposite and different nature could not be learnt at the same time. Here we can hardly agree with him; and, if we may judge by experience, the effect of spending three years between the ages of fourteen and seventeen in mere bodily exercise would be far from improving to the intellect. Secondly, he affirms that music and gymnastic are not, as common opinion is apt to imagine, intended, the one for the cultivation of the mind and the other of the body, but that they are both equally designed for the improvement of the mind. The body, in his view, is the servant of the mind; the subjection of the lower to the higher is for the advantage of both. And doubtless the mind may exercise a very great and paramount influence over the body, if exerted not at particular moments and by fits and starts, but continuously, in making preparation for the whole of life. Other Greek writers saw the mischievous tendency of Spartan discipline (Arist. Pol; Thuc.). But only Plato recognized the fundamental error on which the practice was based.
The subject of gymnastic leads Plato to the sister subject of medicine, which he further illustrates by the parallel of law. The modern disbelief in medicine has led in this, as in some other departments of knowledge, to a demand for greater simplicity; physicians are becoming aware that they often make diseases ‘greater and more complicated’ by their treatment of them (Rep.). In two thousand years their art has made but slender progress; what they have gained in the analysis of the parts is in a great degree lost by their feebler conception of the human frame as a whole. They have attended more to the cure of diseases than to the conditions of health; and the improvements in medicine have been more than counterbalanced by the disuse of regular training. Until lately they have hardly thought of air and water, the importance of which was well understood by the ancients; as Aristotle remarks, ‘Air and water, being the elements which we most use, have the greatest effect upon health’ (Polit.). For ages physicians have been under the dominion of prejudices which have only recently given way; and now there are as many opinions in medicine as in theology, and an equal degree of scepticism and some want of toleration about both. Plato has several good notions about medicine; according to him, ‘the eye cannot be cured without the rest of the body, nor the body without the mind’ (Charm.). No man of sense, he says in the Timaeus, would take physic; and we heartily sympathize with him in the Laws when he declares that ‘the limbs of the rustic worn with toil will derive more benefit from warm baths than from the prescriptions of a not over wise doctor.’ But we can hardly praise him when, in obedience to the authority of Homer, he depreciates diet, or approve of the inhuman spirit in which he would get rid of invalid and useless lives by leaving them to die. He does not seem to have considered that the ‘bridle of Theages’ might be accompanied by qualities which were of far more value to the State than the health or strength of the citizens; or that the duty of taking care of the helpless might be an important element of education in a State. The physician himself (this is a delicate and subtle observation) should not be a man in robust health; he should have, in modern phraseology, a nervous temperament; he should have experience of disease in his own person, in order that his powers of observation may be quickened in the case of others.
The perplexity of medicine is paralleled by the perplexity of law; in which, again, Plato would have men follow the golden rule of simplicity. Greater matters are to be determined by the legislator or by the oracle of Delphi, lesser matters are to be left to the temporary regulation of the citizens themselves. Plato is aware that laissez faire is an important element of government. The diseases of a State are like the heads of a hydra; they multiply when they are cut off. The true remedy for them is not extirpation but prevention. And the way to prevent them is to take care of education, and education will take care of all the rest. So in modern times men have often felt that the only political measure worth having—the only one which would produce any certain or lasting effect, was a measure of national education. And in our own more than in any previous age the necessity has been recognized of restoring the ever-increasing confusion of law to simplicity and common sense.
When the training in music and gymnastic is completed, there follows the first stage of active and public life. But soon education is to begin again from a new point of view. In the interval between the Fourth and Seventh Books we have discussed the nature of knowledge, and have thence been led to form a higher conception of what was required of us. For true knowledge, according to Plato, is of abstractions, and has to do, not with particulars or individuals, but with universals only; not with the beauties of poetry, but with the ideas of philosophy. And the great aim of education is the cultivation of the habit of abstraction. This is to be acquired through the study of the mathematical sciences. They alone are capable of giving ideas of relation, and of arousing the dormant energies of thought.
Mathematics in the age of Plato comprehended a very small part of that which is now included in them; but they bore a much larger proportion to the sum of human knowledge. They were the only organon of thought which the human mind at that time possessed, and the only measure by which the chaos of particulars could be reduced to rule and order. The faculty which they trained was naturally at war with the poetical or imaginative; and hence to Plato, who is everywhere seeking for abstractions and trying to get rid of the illusions of sense, nearly the whole of education is contained in them. They seemed to have an inexhaustible application, partly because their true limits were not yet understood. These Plato himself is beginning to investigate; though not aware that number and figure are mere abstractions of sense, he recognizes that the forms used by geometry are borrowed from the sensible world. He seeks to find the ultimate ground of mathematical ideas in the idea of good, though he does not satisfactorily explain the connexion between them; and in his conception of the relation of ideas to numbers, he falls very far short of the definiteness attributed to him by Aristotle (Met.). But if he fails to recognize the true limits of mathematics, he also reaches a point beyond them; in his view, ideas of number become secondary to a higher conception of knowledge. The dialectician is as much above the mathematician as the mathematician is above the ordinary man. The one, the self-proving, the good which is the higher sphere of dialectic, is the perfect truth to which all things ascend, and in which they finally repose.
This self-proving unity or idea of good is a mere vision of which no distinct explanation can be given, relative only to a particular stage in Greek philosophy. It is an abstraction under which no individuals are comprehended, a whole which has no parts (Arist., Nic. Eth.). The vacancy of such a form was perceived by Aristotle, but not by Plato. Nor did he recognize that in the dialectical process are included two or more methods of investigation which are at variance with each other. He did not see that whether he took the longer or the shorter road, no advance could be made in this way. And yet such visions often have an immense effect; for although the method of science cannot anticipate science, the idea of science, not as it is, but as it will be in the future, is a great and inspiring principle. In the pursuit of knowledge we are always pressing forward to something beyond us; and as a false conception of knowledge, for example the scholastic philosophy, may lead men astray during many ages, so the true ideal, though vacant, may draw all their thoughts in a right direction. It makes a great difference whether the general expectation of knowledge, as this indefinite feeling may be termed, is based upon a sound judgment. For mankind may often entertain a true conception of what knowledge ought to be when they have but a slender experience of facts. The correlation of the sciences, the consciousness of the unity of nature, the idea of classification, the sense of proportion, the unwillingness to stop short of certainty or to confound probability with truth, are important principles of the higher education. Although Plato could tell us nothing, and perhaps knew that he could tell us nothing, of the absolute truth, he has exercised an influence on the human mind which even at the present day is not exhausted; and political and social questions may yet arise in which the thoughts of Plato may be read anew and receive a fresh meaning.
The Idea of good is so called only in the Republic, but there are traces of it in other dialogues of Plato. It is a cause as well as an idea, and from this point of view may be compared with the creator of the Timaeus, who out of his goodness created all things. It corresponds to a certain extent with the modern conception of a law of nature, or of a final cause, or of both in one, and in this regard may be connected with the measure and symmetry of the Philebus. It is represented in the Symposium under the aspect of beauty, and is supposed to be attained there by stages of initiation, as here by regular gradations of knowledge. Viewed subjectively, it is the process or science of dialectic. This is the science which, according to the Phaedrus, is the true basis of rhetoric, which alone is able to distinguish the natures and classes of men and things; which divides a whole into the natural parts, and reunites the scattered parts into a natural or organized whole; which defines the abstract essences or universal ideas of all things, and connects them; which pierces the veil of hypotheses and reaches the final cause or first principle of all; which regards the sciences in relation to the idea of good. This ideal science is the highest process of thought, and may be described as the soul conversing with herself or holding communion with eternal truth and beauty, and in another form is the everlasting question and answer—the ceaseless interrogative of Socrates. The dialogues of Plato are themselves examples of the nature and method of dialectic. Viewed objectively, the idea of good is a power or cause which makes the world without us correspond with the world within. Yet this world without us is still a world of ideas. With Plato the investigation of nature is another department of knowledge, and in this he seeks to attain only probable conclusions (Timaeus).
If we ask whether this science of dialectic which Plato only half explains to us is more akin to logic or to metaphysics, the answer is that in his mind the two sciences are not as yet distinguished, any more than the subjective and objective aspects of the world and of man, which German philosophy has revealed to us. Nor has he determined whether his science of dialectic is at rest or in motion, concerned with the contemplation of absolute being, or with a process of development and evolution. Modern metaphysics may be described as the science of abstractions, or as the science of the evolution of thought; modern logic, when passing beyond the bounds of mere Aristotelian forms, may be defined as the science of method. The germ of both of them is contained in the Platonic dialectic; all metaphysicians have something in common with the ideas of Plato; all logicians have derived something from the method of Plato. The nearest approach in modern philosophy to the universal science of Plato, is to be found in the Hegelian ‘succession of moments in the unity of the idea.’ Plato and Hegel alike seem to have conceived the world as the correlation of abstractions; and not impossibly they would have understood one another better than any of their commentators understand them (Swift’s Voyage to Laputa. ‘Having a desire to see those ancients who were most renowned for wit and learning, I set apart one day on purpose. I proposed that Homer and Aristotle might appear at the head of all their commentators; but these were so numerous that some hundreds were forced to attend in the court and outward rooms of the palace. I knew, and could distinguish these two heroes, at first sight, not only from the crowd, but from each other. Homer was the taller and comelier person of the two, walked very erect for one of his age, and his eyes were the most quick and piercing I ever beheld. Aristotle stooped much, and made use of a staff. His visage was meagre, his hair lank and thin, and his voice hollow. I soon discovered that both of them were perfect strangers to the rest of the company, and had never seen or heard of them before. And I had a whisper from a ghost, who shall be nameless, “That these commentators always kept in the most distant quarters from their principals, in the lower world, through a consciousness of shame and guilt, because they had so horribly misrepresented the meaning of these authors to posterity.” I introduced Didymus and Eustathius to Homer, and prevailed on him to treat them better than perhaps they deserved, for he soon found they wanted a genius to enter into the spirit of a poet. But Aristotle was out of all patience with the account I gave him of Scotus and Ramus, as I presented them to him; and he asked them “whether the rest of the tribe were as great dunces as themselves?”’). There is, however, a difference between them: for whereas Hegel is thinking of all the minds of men as one mind, which developes the stages of the idea in different countries or at different times in the same country, with Plato these gradations are regarded only as an order of thought or ideas; the history of the human mind had not yet dawned upon him.
Many criticisms may be made on Plato’s theory of education. While in some respects he unavoidably falls short of modern thinkers, in others he is in advance of them. He is opposed to the modes of education which prevailed in his own time; but he can hardly be said to have discovered new ones. He does not see that education is relative to the characters of individuals; he only desires to impress the same form of the state on the minds of all. He has no sufficient idea of the effect of literature on the formation of the mind, and greatly exaggerates that of mathematics. His aim is above all things to train the reasoning faculties; to implant in the mind the spirit and power of abstraction; to explain and define general notions, and, if possible, to connect them. No wonder that in the vacancy of actual knowledge his followers, and at times even he himself, should have fallen away from the doctrine of ideas, and have returned to that branch of knowledge in which alone the relation of the one and many can be truly seen—the science of number. In his views both of teaching and training he might be styled, in modern language, a doctrinaire; after the Spartan fashion he would have his citizens cast in one mould; he does not seem to consider that some degree of freedom, ‘a little wholesome neglect,’ is necessary to strengthen and develope the character and to give play to the individual nature. His citizens would not have acquired that knowledge which in the vision of Er is supposed to be gained by the pilgrims from their experience of evil.
On the other hand, Plato is far in advance of modern philosophers and theologians when he teaches that education is to be continued through life and will begin again in another. He would never allow education of some kind to cease; although he was aware that the proverbial saying of Solon, ‘I grow old learning many things,’ cannot be applied literally. Himself ravished with the contemplation of the idea of good, and delighting in solid geometry (Rep.), he has no difficulty in imagining that a lifetime might be passed happily in such pursuits. We who know how many more men of business there are in the world than real students or thinkers, are not equally sanguine. The education which he proposes for his citizens is really the ideal life of the philosopher or man of genius, interrupted, but only for a time, by practical duties,—a life not for the many, but for the few.
Yet the thought of Plato may not be wholly incapable of application to our own times. Even if regarded as an ideal which can never be realized, it may have a great effect in elevating the characters of mankind, and raising them above the routine of their ordinary occupation or profession. It is the best form under which we can conceive the whole of life. Nevertheless the idea of Plato is not easily put into practice. For the education of after life is necessarily the education which each one gives himself. Men and women cannot be brought together in schools or colleges at forty or fifty years of age; and if they could the result would be disappointing. The destination of most men is what Plato would call ‘the Den’ for the whole of life, and with that they are content. Neither have they teachers or advisers with whom they can take counsel in riper years. There is no ‘schoolmaster abroad’ who will tell them of their faults, or inspire them with the higher sense of duty, or with the ambition of a true success in life; no Socrates who will convict them of ignorance; no Christ, or follower of Christ, who will reprove them of sin. Hence they have a difficulty in receiving the first element of improvement, which is self-knowledge. The hopes of youth no longer stir them; they rather wish to rest than to pursue high objects. A few only who have come across great men and women, or eminent teachers of religion and morality, have received a second life from them, and have lighted a candle from the fire of their genius.
The want of energy is one of the main reasons why so few persons continue to improve in later years. They have not the will, and do not know the way. They ‘never try an experiment,’ or look up a point of interest for themselves; they make no sacrifices for the sake of knowledge; their minds, like their bodies, at a certain age become fixed. Genius has been defined as ‘the power of taking pains’; but hardly any one keeps up his interest in knowledge throughout a whole life. The troubles of a family, the business of making money, the demands of a profession destroy the elasticity of the mind. The waxen tablet of the memory which was once capable of receiving ‘true thoughts and clear impressions’ becomes hard and crowded; there is not room for the accumulations of a long life (Theaet.). The student, as years advance, rather makes an exchange of knowledge than adds to his stores. There is no pressing necessity to learn; the stock of Classics or History or Natural Science which was enough for a man at twenty-five is enough for him at fifty. Neither is it easy to give a definite answer to any one who asks how he is to improve. For self-education consists in a thousand things, commonplace in themselves,—in adding to what we are by nature something of what we are not; in learning to see ourselves as others see us; in judging, not by opinion, but by the evidence of facts; in seeking out the society of superior minds; in a study of lives and writings of great men; in observation of the world and character; in receiving kindly the natural influence of different times of life; in any act or thought which is raised above the practice or opinions of mankind; in the pursuit of some new or original enquiry; in any effort of mind which calls forth some latent power.
If any one is desirous of carrying out in detail the Platonic education of after-life, some such counsels as the following may be offered to him:—That he shall choose the branch of knowledge to which his own mind most distinctly inclines, and in which he takes the greatest delight, either one which seems to connect with his own daily employment, or, perhaps, furnishes the greatest contrast to it. He may study from the speculative side the profession or business in which he is practically engaged. He may make Homer, Dante, Shakespeare, Plato, Bacon the friends and companions of his life. He may find opportunities of hearing the living voice of a great teacher. He may select for enquiry some point of history or some unexplained phenomenon of nature. An hour a day passed in such scientific or literary pursuits will furnish as many facts as the memory can retain, and will give him ‘a pleasure not to be repented of’ (Timaeus). Only let him beware of being the slave of crotchets, or of running after a Will o’ the Wisp in his ignorance, or in his vanity of attributing to himself the gifts of a poet or assuming the air of a philosopher. He should know the limits of his own powers. Better to build up the mind by slow additions, to creep on quietly from one thing to another, to gain insensibly new powers and new interests in knowledge, than to form vast schemes which are never destined to be realized. But perhaps, as Plato would say, ‘This is part of another subject’ (Tim.); though we may also defend our digression by his example (Theaet.).
