With regard to the relation of novelty to pleasure and pain, the novel and the sense of the novel is always in its inception under evolution by natural selection unpleasant and painful. A novel experience is one which can only originate in painful struggle, and the new is always _per se_ distasteful to early mind, which is ever conservative in its instincts and tendencies. A perfect life, biologically speaking, is one which is perfectly adapted to its environment, and so goes through its evolution with mechanically exact adjustment to circumstances; and the novel would break in upon the unconscious rhythm which is here perfected. Habituation becomes so iron fast that the novel, even when distinctly pleasurable in itself, is resented, much less is the novel sought for its own sake. However, so far as a novel experience may come rather by way of regressiveness than progressiveness, it may delight us by its novelty whenever the mind becomes capable of appreciating novelty. Thus purely hereditary tendencies, which we do not accomplish but which are accomplished in us during youth, as, for instance, the sexual evolution, may charm, not only in themselves, but for their novelty as well. But this experience which is not merely novel to the individual as springing up spontaneously by _impetus_ from the past, but which is novel for the race, and requires effort to assimilate, and so is in the distinct line of higher evolution, as, the achieving a high spiritual sentimentality in love; this, the real novel, is inevitably and naturally painful. The first time the emotion of humility—a comparatively recent evolution—was experienced by a human being was a truly novel experience, though it is quite uncertain whether there was with it either sense or sentiment of novelty. If the novel and the novel experience—and these terms are practically identical—are essentially painful, whence and how arises the peculiar pleasure which we undeniably may experience in connection with the novel appreciated as such? Must all such pleasure be placed to the account of regressiveness? But pleasure of this kind is intrinsic in the act itself and not for its novelty _per se_. There is a wide variety of experience intrinsically either pleasurable or painful, which may be pleasurable to us solely by reason of its novelty. I may enjoy the novel experience of tasting a pomegranate, be the actual experience agreeable or disagreeable, merely enjoying the novelty as such. What is this novelty, why is it noticed, and why does it give occasion to pleasure or pain in emotional form? As we have already pointed out, the sense of the novel and emotion about it cannot be said to arise with novel experiences in general. The novel in the objective sense is the first occurrence of any given definite kind of psychosis, as humility or pity, in the history of mind, and this novelty is probably not at first appreciated.
