§ 42. (1) Corporal punishment implies physical pain. Generally it consists of a whipping, and this is perfectly justifiable in case of persistent defiance of authority, of obstinate carelessness, or of malicious evil-doing, so long or so often as the higher perceptions of the offender are closed against appeal. But it must not be administered too often, or with undue severity. To resort to deprivation of food is cruel. But, while we condemn the false view of seeing in the rod the only panacea for all embarrassing questions of discipline on the teacher's part, we can have no sympathy for the sentimentality which assumes that the dignity of humanity is affected by a blow given to a child. It is wrong thus to confound self-conscious humanity with child-humanity, for to the average child himself a blow is the most natural form of retribution, and that in which all other efforts at influence at last end. The fully grown man ought, certainly, not to be flogged, for this kind of punishment places him on a level with the child; or, where it is barbarously inflicted, reduces him to the level of the brute, and thus absolutely does degrade him. In English schools the rod is said to be often used; if a pupil of the first class, who is never flogged, is put back into the second, he becomes again subject to flogging. But, even if this be necessary in the schools, it certainly has no proper place in the army and navy. § 43. (2) To punish a pupil by isolation is to remove him temporarily from the society of his fellows. The boy or girl thus cut off from companionship, and forced to think only of himself, begins to understand how helpless he is in such a position. Time passes wearily, and he is soon eager to return to the companionship of parents, brothers and sisters, teachers and fellow-students. But to leave a child entirely by himself without any supervision, and perhaps in a dark room, is as wrong as to leave two or three together without supervision. It often happens when they are kept after school by themselves that they give the freest rein to their childish wantonness, and commit the wildest pranks. § 44. (3) Shutting children up in this way does not touch their sense of honor, and the punishment is soon forgotten, because it relates only to certain particular phases of their behavior. But it is quite different when the pupil is isolated from his fellows on the ground that by his conduct he has violated the very principles which make civilized society possible, and is, therefore, no longer a proper member of it. This is a punishment which touches his sense of honor, for honor is the recognition of the individual by others as their equal, and by his error, or by his crime, he had forfeited his right to be their equal, their peer, and has thus severed himself from them.
