Principia Ethica · G. E. Moore
THE SUBJECT-MATTER OF ETHICS.
Now, I do not wish the importance I assign to this fallacy to be misunderstood. The discovery of it does not at all refute Bentham’s contention that greatest happiness is the proper end of human action, if that be understood as an ethical proposition, as he undoubtedly intended it. That principle may be true all the same; we shall consider whether it is so in succeeding chapters. Bentham might have maintained it, as Professor Sidgwick does, even if the fallacy had been pointed out to him. What I am maintaining is that the _reasons_ which he actually gives for his ethical proposition are fallacious ones so far as they consist in a definition of right. What I suggest is that he did not perceive them to be fallacious; that, if he had done so, he would have been led to seek for other reasons in support of his Utilitarianism; and that, had he sought for other reasons, he _might_ have found none which he thought to be sufficient. In that case he would have changed his whole system--a most important consequence. It is undoubtedly also possible that he would have thought other reasons to be sufficient, and in that case his ethical system, in its main results, would still have stood. But, even in this latter case, his use of the fallacy would be a serious objection to him as an ethical philosopher. For it is the business of Ethics, I must insist, not only to obtain true results, but also to find valid reasons for them. The direct object of Ethics is knowledge and not practice; and any one who uses the naturalistic fallacy has certainly not fulfilled this first object, however correct his practical principles may be.
My objections to Naturalism are then, in the first place, that it offers no reason at all, far less any valid reason, for any ethical principle whatever; and in this it already fails to satisfy the requirements of Ethics, as a scientific study. But in the second place I contend that, though it gives a reason for no ethical principle, it is a _cause_ of the acceptance of false principles--it deludes the mind into accepting ethical principles, which are false; and in this it is contrary to every aim of Ethics. It is easy to see that if we start with a definition of right conduct as conduct conducive to general happiness; then, knowing that right conduct is universally conduct conducive to the good, we very easily arrive at the result that the good is general happiness. If, on the other hand, we once recognise that we must start our Ethics without a definition, we shall be much more apt to look about us, before we adopt any ethical principle whatever; and the more we look about us, the less likely are we to adopt a false one. It may be replied to this: Yes, but we shall look about us just as much, before we settle on our definition, and are therefore just as likely to be right.
But I will try to shew that this is not the case. If we start with the conviction that a definition of good can be found, we start with the conviction that good _can mean_ nothing else than some one property of things; and our only business will then be to discover what that property is. But if we recognise that, so far as the meaning of good goes, anything whatever may be good, we start with a much more open mind. Moreover, apart from the fact that, when we think we have a definition, we cannot logically defend our ethical principles in any way whatever, we shall also be much less apt to defend them well, even if illogically. For we shall start with the conviction that good must mean so and so, and shall therefore be inclined either to misunderstand our opponent’s arguments or to cut them short with the reply, ‘This is not an open question: the very meaning of the word decides it; no one can think otherwise except through confusion.’
It is certain that in different circumstances the same action may produce effects which are utterly different in all respects upon which the value of the effects depends. Hence we can never be entitled to more than a _generalisation_--to a proposition of the form ‘This result _generally_ follows this kind of action’; and even this generalisation will only be true, if the circumstances under which the action occurs are generally the same. This is in fact the case, to a great extent, within any one particular age and state of society. But, when we take other ages into account, in many most important cases the normal circumstances of a given kind of action will be so different, that the generalisation which is true for one will not be true for another. With regard then to ethical judgments which assert that a certain kind of action is good as a means to a certain kind of effect, none will be _universally_ true; and many, though _generally_ true at one period, will be generally false at others. But (2) we require to know not only that _one_ good effect will be produced, but that, among all subsequent events affected by the action in question, the balance of good will be greater than if any other possible action had been performed.
In other words, to judge that an action is generally a means to good is to judge not only that it generally does _some_ good, but that it generally does the greatest good of which the circumstances admit. In this respect ethical judgments about the effects of action involve a difficulty and a complication far greater than that involved in the establishment of scientific laws. For the latter we need only consider a single effect; for the former it is essential to consider not only this, but the effects of that effect, and so on as far as our view into the future can reach. It is, indeed, obvious that our view can never reach far enough for us to be certain that any action will produce the best possible effects. We must be content, if the greatest possible balance of good seems to be produced within a limited period. But it is important to notice that the whole series of effects within a period of considerable length is actually taken account of in our common judgments that an action is good as a means; and that hence this additional complication, which makes ethical generalisations so far more difficult to establish than scientific laws, is one which is involved in actual ethical discussions, and is of practical importance. The commonest rules of conduct involve such considerations as the balancing of future bad health against immediate gains; and even if we can never settle with any certainty how we shall secure the greatest possible total of good, we try at least to assure ourselves that probable future evils will not be greater than the immediate good.
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 may be realised by any of the three cases:--(_a_) If the action itself has greater intrinsic value than any alternative, whereas both its consequences and those of the alternatives are absolutely devoid either of intrinsic merit or intrinsic demerit; or (_b_) if, though its consequences are intrinsically bad, the balance of intrinsic value is greater than would be produced by any alternative; or (_c_) if, its consequences being intrinsically good, the degree of value belonging to them and it conjointly is greater than that of any alternative series. In short, to assert that a certain line of conduct is, at a given time, absolutely right or obligatory, is obviously to assert that more good or less evil will exist in the world, if it be adopted, than if anything else be done instead. But this implies a judgment as to the value both of its own consequences and of those of any possible alternative. And that an action will have such and such consequences involves a number of causal judgments.
Similarly, in answering the question ‘What ought we to aim at securing?’ causal judgments are again involved, but in a somewhat different way. We are liable to forget, because it is so obvious, that this question can never be answered correctly except by naming something which _can_ be secured. Not everything can be secured; and, even if we judge that nothing which cannot be obtained would be of equal value with that which can, the possibility of the latter, as well as its value, is essential to its being a proper end of action. Accordingly neither our judgments as to what actions we ought to perform, nor even our judgments as to the ends which they ought to produce, are pure judgments of intrinsic value. With regard to the former, an action which is absolutely obligatory _may_ have no intrinsic value whatsoever; that it is perfectly virtuous may mean merely that it causes the best possible effects.
And with regard to the latter, these best possible results which justify our action can, in any case, have only so much of intrinsic value as the laws of nature allow us to secure; and they in their turn _may_ have no intrinsic value whatsoever, but may merely be a means to the attainment (in a still further future) of something that has such value. Whenever, therefore, we ask ‘What ought we to do?’ or ‘What ought we to try to get?’ we are asking questions which involve a correct answer to two others, completely different in kind from one another. We must know _both_ what degree of intrinsic value different things have, _and_ how these different things may be obtained. But the vast majority of questions which have actually been discussed in Ethics--_all_ practical questions, indeed--involve this double knowledge; and they have been discussed without any clear separation of the two distinct questions involved. A great part of the vast disagreements prevalent in Ethics is to be attributed to this failure in analysis. By the use of conceptions which involve both that of intrinsic value and that of causal relation, as if they involved intrinsic value only, two different errors have been rendered almost universal.
Either it is assumed that nothing has intrinsic value which is not possible, or else it is assumed that what is necessary must have intrinsic value. Hence the primary and peculiar business of Ethics, the determination what things have intrinsic value and in what degrees, has received no adequate treatment at all. And on the other hand a _thorough_ discussion of means has been also largely neglected, owing to an obscure perception of the truth that it is perfectly irrelevant to the question of intrinsic values. But however this may be, and however strongly any particular reader may be convinced that some one of the mutually contradictory systems which hold the field has given a correct answer either to the question what has intrinsic value, or to the question what we ought to do, or to both, it must at least be admitted that the questions what is best in itself and what will bring about the best possible, are utterly distinct; that both belong to the actual subject-matter of Ethics; and that the more clearly distinct questions are distinguished, the better is our chance of answering both correctly.
Now it is certainly true that all judgments of intrinsic value are in this sense universal; but the principle which I have now to enunciate may easily make it appear as if they were not so but resembled the judgment of means in being merely general. There is, as will presently be maintained, a vast number of different things, each of which has intrinsic value; there are also very many which are positively bad; and there is a still larger class of things, which appear to be indifferent. But a thing belonging to any of these three classes may occur as part of a whole, which includes among its other parts other things belonging both to the same and to the other two classes; and these wholes, as such, may also have intrinsic value. The paradox, to which it is necessary to call attention, is that _the value of such a whole bears no regular proportion to the sum of the values of its parts_. It is certain that a good thing may exist in such a relation to another good thing that the value of the whole thus formed is immensely greater than the sum of the values of the two good things.
It is certain that a whole formed of a good thing and an indifferent thing may have immensely greater value than that good thing itself possesses. It is certain that two bad things or a bad thing and an indifferent thing may form a whole much worse than the sum of badness of its parts. And it seems as if indifferent things may also be the sole constituents of a whole which has great value, either positive or negative. Whether the addition of a bad thing to a good whole may increase the positive value of the whole, or the addition of a bad thing to a bad may produce a whole having positive value, may seem more doubtful; but it is, at least, possible, and this possibility must be taken into account in our ethical investigations. However we may decide particular questions, the principle is clear. _The value of a whole must not be assumed to be the same as the sum of the values of its parts._
A single instance will suffice to illustrate the kind of relation in question. It seems to be true that to be conscious of a beautiful object is a thing of great intrinsic value; whereas the same object, if no one be conscious of it, has certainly comparatively little value, and is commonly held to have none at all. But the consciousness of a beautiful object is certainly a whole of some sort in which we can distinguish as parts the object on the one hand and the being conscious on the other. Now this latter factor occurs as part of a different whole, whenever we are conscious of anything; and it would seem that some of these wholes have at all events very little value, and may even be indifferent or positively bad. Yet we cannot always attribute the slightness of their value to any positive demerit in the object which differentiates them from the consciousness of beauty; the object itself may approach as near as possible to absolute neutrality. Since, therefore, mere consciousness does not always confer great value upon the whole of which it forms a part, even though its object may have no great demerit, we cannot attribute the great superiority of the consciousness of a beautiful thing over the beautiful thing itself to the mere addition of the value of consciousness to that of the beautiful thing. Whatever the intrinsic value of consciousness may be, it does not give to the whole of which it forms a part a value proportioned to the sum of its value and that of its object. If this be so, we have here an instance of a whole possessing a different intrinsic value from the sum of that of its parts; and whether it be so or not, what is meant by such a difference is illustrated by this case.
The existence of the means has no intrinsic value; and its utter annihilation would leave the value of that which it is now necessary to secure entirely unchanged. But in the case of a part of such a whole as we are now considering, it is otherwise. In this case the good in question cannot conceivably exist, unless the part exist also. The necessity which connects the two is quite independent of natural law. What is asserted to have intrinsic value is the existence of the whole; and the existence of the whole includes the existence of its part. Suppose the part removed, and what remains is _not_ what was asserted to have intrinsic value; but if we suppose a means removed, what remains is just what _was_ asserted to have intrinsic value. And yet (2) the existence of the part may _itself_ have no more intrinsic value than that of the means. It is this fact which constitutes the paradox of the relation which we are discussing. It has just been said that what has intrinsic value is the existence of the whole, and that this includes the existence of the part; and from this it would seem a natural inference that the existence of the part has intrinsic value.
But the inference would be as false as if we were to conclude that, because the number of two stones was two, each of the stones was also two. The part of a valuable whole retains exactly the same value when it is, as when it is not, a part of that whole. If it had value under other circumstances, its value is not any greater, when it is part of a far more valuable whole; and if it had no value by itself, it has none still, however great be that of the whole of which it now forms a part. We are not then justified in asserting that one and the same thing is under some circumstances intrinsically good, and under others not so; as we are justified in asserting of a means that it sometimes does and sometimes does not produce good results. And yet we are justified in asserting that it is far more desirable that a certain thing should exist under some circumstances than under others; namely when other things will exist in such relations to it as to form a more valuable whole. _It_ will not have more intrinsic value under these circumstances than under others; _it_ will not necessarily even be a means to the existence of things having more intrinsic value: but it will, like a means, be a necessary condition for the existence of that which _has_ greater intrinsic value, although, unlike a means, it will itself form a part of this more valuable existent.
To say that a thing is an ‘organic whole’ is generally understood to imply that its parts are related to one another and to itself as means to end; it is also understood to imply that they have a property described in some such phrase as that they have ‘no meaning or significance apart from the whole’; and finally such a whole is also treated as if it had the property to which I am proposing that the name should be confined. But those who use the term give us, in general, no hint as to how they suppose these three properties to be related to one another. It seems generally to be assumed that they are identical; and always, at least, that they are necessarily connected with one another. That they are not identical I have already tried to shew; to suppose them so is to neglect the very distinctions pointed out in the last paragraph; and the usage might well be discontinued merely because it encourages such neglect. But a still more cogent reason for its discontinuance is that, so far from being necessarily connected, the second is a property which can attach to nothing, being a self-contradictory conception; whereas the first, if we insist on its most important sense, applies to many cases, to which we have no reason to think that the third applies also, and the third certainly applies to many to which the first does not apply.
But (2) it may also be the case that our body as a whole has a value greater than the sum of values of its parts; and this may be what is meant when it is said that the parts are means to the whole. It is obvious that if we ask the question ‘Why _should_ the parts be such as they are?’ a proper answer may be ‘Because the whole they form has so much value.’ But it is equally obvious that the relation which we thus assert to exist between part and whole is quite different from that which we assert to exist between part and part when we say ‘This part exists, because that one could not exist without it.’ In the latter case we assert the two parts to be causally connected; but, in the former, part and whole cannot be causally connected, and the relation which we assert to exist between them may exist even though the parts are not causally connected either. All the parts of a picture do not have that relation of mutual causal dependence, which certain parts of the body have, and yet the existence of those which do not have it may be absolutely essential to the value of the whole. The two relations are quite distinct in kind, and we cannot infer the existence of the one from that of the other. It can, therefore, serve no useful purpose to include them both under the same name; and if we are to say that a whole is organic because its parts are (in this sense) ‘means’ to the whole, we must _not_ say that it is organic because its parts are causally dependent on one another.
