Well, then, we now proceed to discuss Intuitionistic Hedonism. And the beginning of this discussion marks, it is to be observed, a turning-point in my ethical method. The point I have been labouring hitherto, the point that good is indefinable, and that to deny this involves a fallacy, is a point capable of strict proof: for to deny it involves contradictions. But now we are coming to the question, for the sake of answering which Ethics exists, the question what things or qualities are good. Of any answer to this question no direct proof is possible, and that, just because of our former answer, as to the meaning of good, direct proof was possible. We are now confined to the hope of what Mill calls indirect proof, the hope of determining one another’s intellect; and we are now so confined, just because, in the matter of the former question we are not so confined. Here, then, is an intuition to be submitted to our verdict—the intuition that pleasure alone is good as an end—good in and for itself.(§ 46 ¶ 1)
