Now, I do not wish the importance I assign to this fallacy to be misunderstood. The discovery of it does not at all refute Bentham’s contention that greatest happiness is the proper end of human action, if that be understood as an ethical proposition, as he undoubtedly intended it. That principle may be true all the same; we shall consider whether it is so in succeeding chapters. Bentham might have maintained it, as Professor Sidgwick does, even if the fallacy had been pointed out to him. What I am maintaining is that the _reasons_ which he actually gives for his ethical proposition are fallacious ones so far as they consist in a definition of right. What I suggest is that he did not perceive them to be fallacious; that, if he had done so, he would have been led to seek for other reasons in support of his Utilitarianism; and that, had he sought for other reasons, he _might_ have found none which he thought to be sufficient. In that case he would have changed his whole system--a most important consequence. It is undoubtedly also possible that he would have thought other reasons to be sufficient, and in that case his ethical system, in its main results, would still have stood. But, even in this latter case, his use of the fallacy would be a serious objection to him as an ethical philosopher. For it is the business of Ethics, I must insist, not only to obtain true results, but also to find valid reasons for them. The direct object of Ethics is knowledge and not practice; and any one who uses the naturalistic fallacy has certainly not fulfilled this first object, however correct his practical principles may be.
