And note another point that is brought out by this discussion. Mill’s judgment of preference, so far from establishing the principle that pleasure alone is good, is obviously inconsistent with it. He admits that experts can judge whether one pleasure is more desirable than another, because pleasures differ in quality. But what does this mean? If one pleasure can differ from another in quality, that means, that a pleasure is something complex, something composed, in fact, of pleasure in addition to that which produces pleasure. For instance, Mill speaks of sensual indulgences as lower pleasures. But what is a sensual indulgence? It is surely a certain excitement of some sense together with the pleasure caused by such excitement. Mill, therefore, in admitting that a sensual indulgence can be directly judged to be lower than another pleasure, in which the degree of pleasure involved may be the same, is admitting that other things may be good, or bad, quite independently of the pleasure which accompanies them. A pleasure is, in fact, merely a misleading term which conceals the fact that what we are dealing with is not pleasure but something else, which may indeed necessarily produce pleasure, but is nevertheless quite distinct from it. (§ 48 ¶ 1)

Mill, therefore, in thinking that to estimate quality of pleasure is quite consistent with his hedonistic principle that pleasure and absence of pain alone are desirable as ends has again committed the fallacy of confusing ends and means. For take even the most favourable supposition of his meaning; let us suppose that by a pleasure he does not mean, as his words imply, that which produces pleasure and the pleasure produced. Let us suppose him to mean that there are various kinds of pleasure, in the sense in which there are various kinds of colour—blue, red, green, etc. Even in this case, if we are to say that our end is colour alone, then, although it is impossible we should have colour without having some particular colour, yet the particular colour we must have, is only a means to our having colour, if colour is really our end. And if colour is our only possible end, as Mill says pleasure is, then there can be no possible reason for preferring one colour to another, red, for instance, to blue, except that the one is more of a colour than the other. Yet the opposite of this is what Mill is attempting to hold with regard to pleasures. (§ 48 ¶ 2)

Accordingly a consideration of Mill’s view that some pleasures are superior to others in quality brings out one point which may help to determine the intellect with regard to the intuition Pleasure is the only good. For it brings out the fact that if you say pleasure, you must mean pleasure: you must mean some one thing common to all different pleasures, some one thing, which may exist in different degrees, but which cannot differ in kind. I have pointed out that, if you say, as Mill does, that quality of pleasure is to be taken into account, then you are no longer holding that pleasure alone is good as an end, since you imply that something else, something which is not present in all pleasures, is also good as an end. The illustration I have given from colour expresses this point in its most acute form. It is plain that if you say Colour alone is good as an end, then you can give no possible reason for preferring one colour to another. Your only standard of good and bad will then be colour; and since red and blue both conform equally to this, the only standard, you can have no other whereby to judge whether red is better than blue. It is true that you cannot have colour unless you also have one or all of the particular colours: they, therefore, if colour is the end, will all be good as means, but none of them can be better than another even as a means, far less can any one of them be regarded as an end in itself. Just so with pleasure: If we do really mean Pleasure alone is good as an end, then we must agree with Bentham that Quantity of pleasure being equal, pushpin is as good as poetry. To have thus dismissed Mill’s reference to quality of pleasure, is therefore to have made one step in the desired direction. The reader will now no longer be prevented from agreeing with me, by any idea that the hedonistic principle Pleasure alone is good as an end is consistent with the view that one pleasure may be of a better quality than another. These two views, we have seen, are contradictory to one another. We must choose between them: and if we choose the latter, then we must give up the principle of Hedonism. (§ 48 ¶ 3)
