17. There are, then, judgments which state that certain kinds of things have good effects; and such judgments, for the reasons just given, have the important characteristics (1) that they are unlikely to be true, if they state that the kind of thing in question always has good effects, and (2) that, even if they only state that it generally has good effects, many of them will only be true of certain periods in the world’s history. On the other hand there are judgments which state that certain kinds of things are themselves good; and these differ from the last in that, if true at all, they are all of them universally true. It is, therefore, extremely important to distinguish these two kinds of possible judgments. Both may be expressed in the same language: in both cases we commonly say “Such and such a thing is good.” But in the one case “good” will mean “good as means,” i.e. merely that the thing is a means to good—will have good effects: in the other case it will mean “good as end”—we shall be judging that the thing itself has the property which, in the first case, we asserted only to belong to its effects. It is plain that these are very different assertions to make about a thing; it is plain that either or both of them may be made, both truly and falsely, about all manner of things; and it is certain that unless we are clear as to which of the two we mean to assert, we shall have a very poor chance of deciding rightly whether our assertion is true or false. It is precisely this clearness as to the meaning of the question asked which has hitherto been almost entirely lacking in ethical speculation. Ethics has always been predominantly concerned with the investigation of a limited class of actions. With regard to these we may ask both how far they are good in themselves and how far they have a general tendency to produce good results. And the arguments brought forward in ethical discussion have always been of both classes—both such as would prove the conduct in question to be good in itself and such as would prove it to be good as a means. But that these are the only questions which any ethical discussion can have to settle, and that to settle the one is not the same thing as to settle the other—these two fundamental facts have in general escaped the notice of ethical philosophers. Ethical questions are commonly asked in an ambiguous form. It is asked “What is a man’s duty under these circumstances?” or “Is it right to act in this way?” or “What ought we to aim at securing?” But all these questions are capable of further analysis; a correct answer to any of them involves both judgments of what is good in itself and causal judgments. This is implied even by those who maintain that we have a direct and immediate judgment of absolute rights and duties. Such a judgment can only mean that the course of action in question is the best thing to do; that, by acting so, every good that can be secured will have been secured. Now we are not concerned with the question whether such a judgment will ever be true. The question is: What does it imply, if it is true? And the only possible answer is that, whether true or false, it implies both a proposition as to the degree of goodness of the action in question, as compared with other things, and a number of causal propositions. For it cannot be denied that the action will have consequences: and to deny that the consequences matter is to make a judgment of their intrinsic value, as compared with the action itself. In asserting that the action is the best thing to do, we assert that it together with its consequences presents a greater sum of intrinsic value than any possible alternative. And this condition
