[Education has two stages: from birth to puberty, from puberty to adolescence. The first, consisting of physical and esthetic training to be given at home] Presuming that Education extends from birth to manhood, we may divide it into two periods, the first ending with puberty, that is, at the beginning of industrial apprenticeship. Education here should be essentially spontaneous, and should be carried on as far as possible in the bosom of the family. The only studies required should be of an esthetic kind. In the second period, Education takes a systematic form, consisting chiefly of a public course of scientific lectures, explaining the essential laws of the various orders of phenomena. These lectures will be the groundwork of Moral Science, which will co-ordinate the whole, and point out the relation of each part to the social purpose common to all. Thus, at about the time which long experience has fixed as that of legal majority, and when in most cases the term of apprenticeship closes, the workman will be prepared intellectually and morally for his public and private service. The first years of life, from infancy to the end of the period of second dentition, should be devoted to education of the physical powers, carried on under the superintendence of the parents, especially of the mother. Physical education, as usually practised, is nothing but mere muscular exercise; but a more important object is that of training the senses, and giving manual skill, so as to develop from the very first our powers of observation and action. Study, in the ordinary acceptation, there should be none during this period, not even reading or writing. An acquaintance with facts of various kinds, such as may spontaneously attract the growing powers of attention, will be the only instruction received. The philosophic system of the infant individual, like that of the infant species, consists in pure Fetichism, and its natural development should not be disturbed by unwise interference. The only care of the parents will be to impress those feelings and habits for which a rational basis will be given at a later period. By taking every opportunity of calling the higher instincts into play, they will be laying down the best foundation for true morality.
