As he approaches maturity (Book IV) Émile requires “a new occupation which interests him by its novelty, which keeps him in good humor, gives him pleasure, occupies his attention, and keeps him in training—an occupation of which he is passionately fond and in which he is wholly absorbed. Now the only one which seems to me to fulfil all these conditions is hunting.... Émile has everything necessary for success in it: he is robust, dexterous, patient, indefatigable. Without fail he will contract a taste for this exercise; he will throw into it all the ardor of his age; for a time, at least, he will lose in it all the dangerous inclinations which spring from idleness. Hunting toughens the heart as well as the body....” Book V is concerned with the education of Sophie, Émile’s future wife. “... Plato, in his _Republic_, enjoins the same exercises on women as upon men, and in this I think he was right.... Since the body is born, so to speak, before the soul, the first culture ought to be that of the body; and this order is common to both sexes. But the object of this culture is different; in one this object is the development of strength, while in the other it is the development of personal charms. Not that these qualities ought to be exclusive in each sex, but the order is simply reversed: women need sufficient strength to do with grace whatever they have to do; and men need sufficient cleverness to do with facility whatever they have to do. The extreme lack of vigor in women gives rise to the same quality in men. Women ought not to be robust like them, but for them, in order that the men who shall be born of them may be robust also. In this respect the convents, where the boarders have coarse fare, but many frolics, races, and sports in the open air and in gardens, are to be preferred to the home where a girl, delicately reared, always flattered or scolded, always seated under the eyes of her mother in a very close room, dares neither to rise, to walk, to speak, nor to breathe, and has not a moment’s liberty for playing, jumping, running, shouting, and indulging in the petulance natural to her age; always dangerous relaxation or badly conceived severity, but never anything according to reason. This is the way the young are ruined both in body and in heart.... Delicacy is not languor, and one need not be sickly in order to please.”
