§ 149. (_b_) From Renunciation springs the injunction of self-government. The action of education on the will to form habits in it, is discipline or training in a narrower sense. Renunciation teaches us to know the relation in which we in fact, as historical persons, stand to the idea of the Good. From our empirical knowledge of ourselves we derive the idea of our limits; from the absolute knowledge of ourselves on the other hand, which presents to us the nature of Freedom as our own actuality, we derive the conception of the resistless might of the genuine will for the good. But to actualize this conception we must have practice. This practice is the proper renunciation. Every man must devise for himself some special set of rules, which shall be determined by his peculiarities and his resulting temptations. These rules must have as their innermost essence the subduing of self, the vanquishing of his negative arbitrariness by means of the universality and necessity of the will. ——In order to make this easy, the youth may be practised in renouncing for himself even the arbitrariness which is permitted to him. One often speaks of renunciation as if it belonged especially to the middle ages and to Catholicism; but this is an error. Renunciation in its one-sided form as relying on works, and for the purpose of mortification, is asceticism, and belongs to them; but Renunciation in general is a necessary determination of morals. The keeping of a journal is said to assist in the practice of virtue, but its value depends on how it is kept. To one it may be a curse, to another a blessing. Fichte, Göthe, Byron, and others, have kept journals and have been assisted thereby; while others, as Lavater, have been thwarted by them. Vain people will every evening record with pen and ink their admiration of the correct course of life which they have led in the day devoted to their pleasure.——
