himself states elsewhere[1] that Psychological Hedonism is ‘not seldom confounded with Egoistic Hedonism’; and that confusion, as we shall see, rests chiefly on that same fallacy, the naturalistic fallacy, which is implied in Bentham’s statements. Prof. Sidgwick admits therefore that this fallacy is sometimes committed, absurd as it is; and I am inclined to think that Bentham may really have been one of those who committed it. Mill, as we shall see, certainly did commit it. In any case, whether Bentham committed it or not, his doctrine, as above quoted, will serve as a very good illustration of this fallacy, and of the importance of the contrary proposition that good is indefinable.
Let us consider this doctrine. Bentham seems to imply, so Prof. Sidgwick says, that the word ‘right’ means ‘conducive to general happiness.’ Now this, by itself, need not necessarily involve the naturalistic fallacy. For the word ‘right’ is very commonly appropriated to actions which lead to the attainment of what is good; which are regarded as means to the ideal and not as ends-in-themselves. This use of ‘right,’ as denoting what is good as a means, whether or not it also be good as an end, is indeed the use to which I shall confine the word. Had Bentham been using ‘right’ in this sense, it might be perfectly consistent for him to define right as ‘conducive to the general happiness,’ provided only (and note this proviso) he had already proved, or laid down as an axiom, that general happiness was the good, or (what is equivalent to this) that general happiness alone was good. For in that case he would have already defined the good as general happiness (a position perfectly consistent, we have seen, with the contention that ‘good’ is indefinable), and, since right was to be defined as ‘conducive to the good,’ it would actually mean ‘conducive to general happiness.’ But this method of escape from the charge of having committed the naturalistic fallacy has been closed by Bentham himself. For his fundamental principle is, we see, that the greatest happiness of all concerned is the right and proper end of human action. He applies the word ‘right,’ therefore, to the end, as such, not only to the means which are
