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.).
