dwelt upon æsthetically, all we can hazard in reply is that at some leisure moment when unmoved by appetite a surplus of energy set up an habitual sensing activity, as noticing reds, and at a certain stage when some directing is exercised, there comes a unique pleasure from the mere sensing, and the red is therefore _dwelt_ upon. Æsthetic colour-pleasure in the simplest case arises then in every one’s experience. Sense-pleasure is thus distinctly of two kinds, first, as arising in direct connection with general organic demands and satisfactions—the part as serving the whole; second, as arising immediately from the sense-activity—the whole as serving the part. A monkey may find an apple a pleasant sight, but loses all interest when the apple is seen to be an imitation: the monkey has the first pleasure, but not the second. The sensuous æsthetic problem is merely to introspect the quality of the sensing-for-itself-pleasure as distinct from pleasantness coming from the service of life. A sense which develops its own pleasurableness is on a new line, which we term the æsthetic. Æsthetic activity is distinct from mere vent activity of superfluous energy by reason of being carried on self-directed by the felt pleasure of activity; it implies a measure of self-direction and self-consciousness. Æsthetic activity may then be generally described as primarily a sensing carried on, not as means, but for its own sake in pleasure immediately resulting. And we find that in this very general meaning all senses have their æsthetic activity. The temperature sense is carried on, as in basking, for the pure pleasure of warmth. A cat behind a stove is a connoisseur in æsthetic warmth sensations, and enjoys warmth for its own sake, so far as often to injure the organism as a whole. To lie in the sun and experience the thrills of pleasurable warmth and to keep up this sensing merely for the sensation pleasure is a frequent experience even with man. Again, the muscular and pressure senses often have a sphere of æsthetic activity with athletes and lovers of exercise. When in prime condition, a man will toss weights about solely for the pleasure involved in the sense of pressure and of muscular activity. Touch also is plainly æsthetic when one handles silk for the pleasure involved in its smoothness. Smell is obviously an æsthetic activity in smelling perfumes for the pleasure of the smell. It is probable that the æsthetic activity of this sense is far wider in some of the lower animals where the sense is much more acute, as the dog. The dog is plainly having a very different psychosis when he is smelling with pleasure a piece of meat which he is about to eat, and when he sniffs carrion and perfumes himself therewith. He gets thus a certain pleasant but gross stimulation quite akin to the pleasure some men take in musk, an enjoyment of which is distinctly an animal trait. Again, the epicure who sips his rare wine is tasting for the pure
