and especially so in the specific bodily part, and thus to enable the soul, under its volitional and conceptual characters, to exist as substance in its corporeity. In this way an aptitude shows the corporeity rendered completely pervious, made into an instrument, so that when the conception (e.g. a series of musical notes) is in me, then without resistance and with ease the body gives them correct utterance. The form of habit applies to all kinds and grades of mental action. The most external of them, i.e. the spatial direction of an individual, viz. his upright posture, has been by will made a habit—a position taken without adjustment and without consciousness—which continues to be an affair of his persistent will; for the man stands only because and in so far as he wills to stand, and only so long as he wills it without consciousness. Similarly our eyesight is the concrete habit which, without an express adjustment, combines in a single act the several modifications of sensation, consciousness, intuition, intelligence, &c., which make it up. Thinking, too, however free and active in its own pure element it becomes, no less requires habit and familiarity (this impromptuity or form of immediacy), by which it is the property of my single self where I can freely and in all directions range. It is through this habit that I come to realise my _existence_ as a thinking being. Even here, in this spontaneity of self-centred thought, there is a partnership of soul and body (hence, want of habit and too-long-continued thinking cause headache); habit diminishes this feeling, by making the natural function an immediacy of the soul. Habit on an ampler scale, and carried out in the strictly intellectual range, is recollection and memory, whereof we shall speak later. Habit is often spoken of disparagingly and called lifeless, casual and particular. And it is true that the form of habit, like any other, is open to anything we chance to put into it; and it is habit of living which brings on death, or, if quite abstract, is death itself: and yet habit is indispensable for the _existence_ of all intellectual life in the individual, enabling the subject to be a concrete immediacy, an “ideality” of soul—enabling the matter of consciousness, religious, moral, &c., to be his as _this_ self, _this_ soul, and no other, and be neither a mere latent possibility, nor a transient emotion or idea, nor an abstract inwardness, cut off from action and reality, but part and parcel of his being. In scientific studies of the soul and the mind, habit is usually passed over—either as something contemptible—or rather for the further reason that it is one of the most difficult questions of psychology.
