The Republic — Plato

and seventeen in mere bodily exercise would be far from improving to the intellect. Secondly, he affirms that music and gymnastics 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." viii. 4, § I foil. ; Thuc. ii. 37, 39). But only Plato recognized the fundamental error on which the practice was based.

The subject of gymnastics 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." iv. 426 A).

In 2,000 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." vii. 11, § 4).

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. 156 E).

No man of sense, he says in the " Timseus," would take physic ; and we heartily sympathize with him in the " Laws " when he declares that " the limbs of the 2rustic worn with toil will derive more benefit from warm baths than from the prescriptions of a not over wise doctor " (vi. 761 C). But we can hardly praise him when, in obedience to the authority of Homer, he depreciates diet, or approves 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 helpers 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 laisscs 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 everincreasing confusion of law to simplicity and common-sense.

When the training in music and gymnastics 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 lieauties of poetry, but with the ideas of
