Empirical Hedonism

Abstract

§ 1. The first and most fundamental assumption, involved not only in the empirical method of Egoistic Hedonism, but in the very conception of ‘Greatest Happiness’ as an end of action, is the commensurability of Pleasures and Pains. By this I mean that we must assume the pleasures sought and the pains shunned to have determinate quantitative relations to each other; for otherwise they cannot be conceived as possible elements of a total which we are to seek to make as great as possible. It is not absolutely necessary to exclude the supposition that there are some kinds of pleasure so much more pleasant than others, that the smallest conceivable amount of the former would outweigh the greatest conceivable amount of the latter; since, if this were ascertained to be the case, the only result would be that any hedonistic calculation involving pleasures of the former class might be simplified by treating those of the latter class as practically non-existent.¹ I think, however, that in all ordinary prudential reasoning, at any rate, the assumption is implicitly made that all the pleasures and pains that man can experience bear a finite ratio to each other in respect of pleasantness and its opposite.
