It is this ultimate decision with regard to Hedonism at which we must now try to arrive. So far I have been only occupied with refuting Mill’s naturalistic arguments for Hedonism; but the doctrine that pleasure alone is desirable may still be true, although Mill’s fallacies cannot prove it so. This is the question which we have now to face. This proposition, pleasure alone is good or desirable, belongs undoubtedly to that class of propositions, to which Mill at first rightly pretended it belonged, the class of first principles, which are notamenable to direct proof. But in this case, as he also rightly says, considerations may be presented capable of determining the intellect either to give or withhold its assent to the doctrine (p. 7). It is such considerations that Professor Sidgwick presents, and such also that I shall try to present for the opposite view. This proposition that pleasure alone is good as an end, the fundamental proposition of Ethical Hedonism, will then appear, in Professor Sidgwick’s language, as an object of intuition. I shall try to shew you why my intuition denies it, just as his intuition affirms it. It may always be true notwithstanding; neither intuition can prove whether it is true or not; I am bound to be satisfied, if I can present considerations capable of determining the intellect to reject it. (§ 45 ¶ 1)

Now it may be said that this is a very unsatisfactory state of things. It is indeed; but it is important to make a distinction between two different reasons, which may be given for calling it unsatisfactory. Is it unsatisfactory because our principle cannot be proved? or is it unsatisfactory merely because we do not agree with one another about it? I am inclined to think that the latter is the chief reason. For the mere fact that in certain cases proof is impossible does not usually give us the least uneasiness. For instance, nobody can prove that there is a chair beside me; yet I do not suppose that any one is much dissatisfied for that reason. We all agree that it is a chair, and that is enough to content us, although it is quite possible we may be wrong. A madman, of course, might come in and say that it is not a chair but an elephant. We could not prove that he was wrong, and the fact that he did not agree with us might then begin to make us uneasy. Much more, then, shall we be uneasy, if some one, whom we do not think to be mad, disagrees with us. We shall try to argue with him, and we shall probably be content if we lead him to agree with us, although we shall not have proved our point. We can only persuade him by shewing him that our view is consistent with something else which he holds to be true, whereas his original view is contradictory to it. But it will be impossible to prove that that something else, which we both agree to be true, is really so; we shall be satisfied to have settled the matter in dispute by means of it, merely because we are agreed on it. In short, our dissatisfaction in these cases is almost always of the type felt by the poor lunatic in the story. I said the world was mad, says he, and the world said that I was mad; and, confound it, they outvoted me. It is, I say, almost always such a disagreement, and not the impossibility of proof, which makes us call the state of things unsatisfactory. For, indeed, who can prove that proof itself is a warrant of truth? We are all agreed that the laws of logic are true and therefore we accept a result which is proved by their means; but such a proof is satisfactory to us only because we are all so fully agreed that it is a warrant of truth. And yet we cannot, by the nature of the case, prove that we are right in being so agreed. (§ 45 ¶ 2)

Accordingly, I do not think we need be much distressed by our admission that we cannot prove whether pleasure alone is good or not. We may be able to arrive at an agreement notwithstanding; and if so, I think it will be satisfactory. And yet I am not very sanguine about our prospects of such satisfaction. Ethics, and philosophy in general, have always been in a peculiarly unsatisfactory state. There has been no agreement about them, as there is about the existence of chairs and lights and benches. I should therefore be a fool if I hoped to settle one great point of controversy, now and once for all. It is extremely improbable I shall convince. It would be highly presumptuous even to hope that in the end, say two or three centuries hence, it will be agreed that pleasure is not the sole good. Philosophical questions are so difficult, the problems they raise are so complex, that no one can fairly expect, now, any more than in the past, to win more than a very limited assent. And yet I confess that the considerations which I am about to present appear to me to be absolutely convincing. I do think that they ought to convince, if only I can put them well. In any case, I can but try. I shall try now to put an end to that unsatisfactory state of things, of which I have been speaking. I shall try to produce an agreement that the fundamental principle of Hedonism is very like an absurdity, by shewing what it must mean, if it is clearly thought out, and how that clear meaning is in conflict with other beliefs, which will, I hope, not be so easily given up.
