3. "I will omit much usual declamation on the dignity and capacity of our nature: the superiority of the soul to the body, of the rational to the animal part of our constitution; upon the worthiness, refinement, and delicacy of some satisfactions, or the meanness, grossness, and sensuality of others: because I hold that pleasures differ in nothing but in continuance and intensity." (Paley, _Moral Philosophy_, bk. i., c. vi.) In opposition to the above it is here laid down that _delights do not differ in continuance and intensity, that is, in quantity, alone, but likewise in quality_, that is, some are nobler, better, and more becoming a man than others, and therefore preferable on other grounds than those of mere continuance and intensity. I wish to show that the more pleasant pleasure is not always the better pleasure; that even the pleasure which is more durable, and thereby more pleasant in the long run, is not the better of the two simply as carrying the greater _cumulus_ of pleasure. If this is shown, it will follow that pleasure is not identical with good; or that pleasure is not happiness, not the last end of man. 4. Delight comes of activity, not necessarily of change, except so far as activity itself involves change, as it always does in mortal man. Delight sits upon activity, as the bloom upon youth. Bloom is the natural sign of maturity; and the delight that we come to take in doing a thing shows that we are at least beginning to do it well: our activity is approaching perfection. In this sense it is said that _delight perfects activity_. As the activity, so will be the delight. But the activity will be as the power of which it is an exercise. Powers like in kind will supply like activities, and these again will yield delights alike in kind. There is no difference of quality in such delights, they differ in quantity alone. Thus taste and smell are two senses: the difference between them can hardly be called one of kind: therefore the delights of smelling and of tasting fall under one category. We may exchange so much smell for an equal amount of taste: it is a mere matter of quantity. But between sight and hearing on the one hand, and taste and smell and touch on the other, there is a wider difference, due to the fact that intellect allies itself more readily to the operation of the two former senses.
