This emotional feat does not seem to me possible: and therefore I must admit that a man who embraces the principle of Rational Egoism cuts himself off from the special pleasure that attends this absolute sacrifice and abnegation of self. But however exquisite this may be, the pitch of emotional exaltation and refinement necessary to attain it is comparatively so rare, that it is scarcely included in men’s common estimate of happiness. I do not therefore think that an important objection to Rational Egoism can be based upon its incompatibility with this particular consciousness: nor that the common experience of mankind really sustains the view that the desire of one’s own happiness, if accepted as supreme and regulative, inevitably defeats its own aim through the consequent diminution and desiccation of the impulses and emotional capacities necessary to the attainment of happiness in a high degree; though it certainly shows a serious and subtle danger in this direction. § 3. There is, however, another way in which the habit of mind necessarily resulting from the continual practice of hedonistic comparison is sometimes thought to be unfavourable to the attainment of the hedonistic end: from a supposed incompatibility between the habit of reflectively observing and examining pleasure, and the capacity for experiencing pleasure in normal fulness and intensity. And it certainly seems important to consider what effect the continual attention to our pleasures, in order to observe their different degrees, is likely to have on these feelings themselves. The inquiry at first sight seems to lead to irreconcilable contradiction in our view of pleasure. For if pleasure only exists as it is felt, the more conscious we are of it, the more pleasure we have: and it would seem that the more our attention is directed towards it, the more fully we shall be conscious of it. On the other hand Hamilton’s statement that “knowledge and feeling” (cognition and pleasure or pain) are always “in a certain inverse proportion to each other,” corresponds _prima facie_ to our common experience: for the purely cognitive element of consciousness seems to be neither pleasurable nor painful, so that the more our consciousness is occupied with cognition, the less room there seems to be for feeling. This view, however, rests on the assumption that the total intensity of our consciousness is a constant quantity; so that when one element of it positively increases, the rest must positively--as well as relatively--diminish. And it does not appear to me that experience gives us any valid ground for making this general assumption: it rather seems that at certain times in our life intellect and feeling are simultaneously feeble; so that the same mental excitement may intensify both simultaneously.
