It seems, then, clear that Hedonism is in error, so far as it maintains that pleasure alone, and not the consciousness of pleasure, is the sole good. And this error seems largely due to the fallacy which I pointed out above in Mill—the fallacy of confusing means and end. It is falsely supposed that, since pleasure must always be accompanied by consciousness (which is, itself, extremely doubtful), therefore it is indifferent whether we say that pleasure or the consciousness of pleasure is the sole good. Practically, of course, it would be indifferent at which we aimed, if it were certain that we could not get the one without the other; but where the question is of what is good in itself—where we ask: For the sake of what is it desirable to get that which we aim at?—the distinction is by no means unimportant. Here we are placed before an exclusive alternative. Either pleasure by itself (even though we can’t get it) would be all that is desirable, or a consciousness of it would be more desirable still. Both these propositions cannot be true, and I think it is plain that the latter is true; whence it follows that pleasure is not the sole good. (§ 53 ¶ 1)

Still it may be said that, even if consciousness of pleasure, and not pleasure alone, is the sole good, this conclusion is not very damaging to Hedonism. It may be said that Hedonists have always meant by pleasure the consciousness of pleasure, though they have not been at pains to say so; and this, I think is, in the main, true. To correct their formula in this respect could, therefore, only be a matter of practical importance, if it is possible to produce pleasure without producing consciousness of it. But even this importance, which I think our conclusion so far really has, is, I admit, comparatively slight. What I wish to maintain is that even consciousness of pleasure is not the sole good: that, indeed, it is absurd so to regard it. And the chief importance of what has been said so far lies in the fact that the same method, which shews that consciousness of pleasure is more valuable than pleasure, seems also to shew that consciousness of pleasure is itself far less valuable than other things. The supposition that consciousness of pleasure is the sole good is due to a neglect of the same distinctions which have encouraged the careless assertion that pleasure is the sole good. (§ 53 ¶ 2)

The method which I employed in order to shew that pleasure itself was not the sole good, was that of considering what value we should attach to it, if it existed in absolute isolation, stripped of all its usual accompaniments. And this is, in fact, the only method that can be safely used, when we wish to discover what degree of value a thing has in itself. The necessity of employing this method will be best established by a discussion of the arguments used by Prof. Sidgwick in the passage last quoted, and by an exposure of the manner in which they are calculated to mislead.
