INTUITIONISM § 1. The effort to examine, closely but quite neutrally, the system of Egoistic Hedonism, with which we have been engaged in the last Book, may not improbably have produced on the reader’s mind a certain aversion to the principle and method examined, even though (like myself) he may find it difficult not to admit the ‘authority’ of self-love, or the ‘rationality’ of seeking one’s own individual happiness. In considering ‘enlightened self-interest’ as supplying a _prima facie_ tenable principle for the systematisation of conduct, I have given no expression to this sentiment of aversion, being anxious to ascertain with scientific impartiality the results to which this principle logically leads. When, however, we seem to find on careful examination of Egoism (as worked out on a strictly empirical basis) that the common precepts of duty, which we are trained to regard as sacred, must be to the egoist rules to which it is only generally speaking and for the most part reasonable to conform, but which under special circumstances must be decisively ignored and broken,--the offence which Egoism in the abstract gives to our sympathetic and social nature adds force to the recoil from it caused by the perception of its occasional practical conflict with common notions of duty. But further, we are accustomed to expect from Morality clear and decisive precepts or counsels: and such rules as can be laid down for seeking the individual’s greatest happiness cannot but appear wanting in these qualities. A dubious guidance to an ignoble end appears to be all that the calculus of Egoistic Hedonism has to offer. And it is by appealing to the superior certainty with which the dictates of Conscience or the Moral Faculty are issued, that Butler maintains the practical supremacy of Conscience over Self-love, in spite of his admission (in the passage before quoted[151]) of theoretical priority in the claims of the latter.[152] A man knows certainly, he says, what he ought to do: but he does not certainly know what will lead to his happiness.
