§ 410. The soul’s making itself an abstract universal being, and reducing the particulars of feelings (and of consciousness) to a mere feature of its being is Habit. In this manner the soul has the contents in possession, and contains them in such manner that in these features it is not as sentient, nor does it stand in relationship with them as distinguishing itself from them, nor is absorbed in them, but has them and moves in them, without feeling or consciousness of the fact. The soul is freed from them, so far as it is not interested in or occupied with them: and whilst existing in these forms as its possession, it is at the same time open to be otherwise occupied and engaged—say with feeling and with mental consciousness in general. This process of building up the particular and corporeal expressions of feeling into the being of the soul appears as a _repetition_ of them, and the generation of habit as _practice_. For, this being of the soul, if in respect of the natural particular phase it be called an abstract universality to which the former is transmuted, is a reflexive universality (§ 175); i.e. the one and the same, that recurs in a series of units of sensation, is reduced to unity, and this abstract unity expressly stated. Habit, like memory, is a difficult point in mental organisation: habit is the mechanism of self-feeling, as memory is the mechanism of intelligence. The natural qualities and alterations of age, sleep and waking, are “immediately” natural: habit, on the contrary, is the mode of feeling (as well as intelligence, will, &c., so far as they belong to self-feeling) made into a natural and mechanical existence. Habit is rightly called a second nature; nature, because it is an immediate being of the soul; a second nature, because it is an immediacy created by the soul, impressing and moulding the corporeality which enters into the modes of feeling as such and into the representations and volitions so far as they have taken corporeal form (§ 401).
