“It has always seemed to me that the _rapport_ that exists between two human beings, whether of the same or of different sexes, is a force not sufficiently recognised, and capable of producing great results. Plato fully understood its importance, and aimed at giving what to his countrymen was more or less sensual, a noble and exalted direction.… As one who has had much to do in instructing boys and starting them in life, I am convinced that the great secret of being a good teacher consists in the possibility of that _rapport_; not only of a merely intellectual nature, but involving a certain physical element, a personal affection, almost indescribable, that grows up between pupil and teacher, and through which thoughts are shared and an influence created that could exist in no other way.” And it must be evident to every one that to the expanding mind of a small boy to have a relation of real affection with some sensible and helpful elder of his own sex must be a priceless boon. At that age love to the other sex has hardly declared itself, and indeed is not exactly what is wanted. The unformed mind requires an ideal of itself, as it were, to which it can cling or towards which it can grow. Yet it is equally evident that the relation and the success of it, will depend immensely on the character of the elder one, on the self-restraint and tenderness of which he is capable, and on the ideal of life which he has in his mind. That, possibly, is the reason why Greek custom, at least in the early days of Hellas, not only recognised friendships between elder and younger youths as a national institution of great importance, but laid down very distinct laws or rules concerning the conduct of them, so as to be a guide and a help to the elder in what was acknowledged to be a position of responsibility. In Crete, for instance,[52] the friendship was entered into in quite a formal and public way, with the understanding and consent of relatives; the position of the elder was clearly defined, and it became his business to train and exercise the younger in skill of arms, the chase, etc.; while the latter could obtain redress at law if the elder subjected him to insult or injury of any kind. At the end of a certain period of probation, if the younger desired it he could leave his comrade; if not, he became his squire or henchman--the elder being bound to furnish his military equipments--and they fought thenceforward side by side in battle, “inspired with double valor, according to the notions of the Cretans, by the gods of war and love.”[53] Similar customs prevailed in Sparta, and, in a less defined way, in other Greek states; as, indeed, they have prevailed among many semi-barbaric races on the threshold of civilisation.
