“ For though to produce more life is, if the second of Mr Spencer’s propositions be correct, one way of producing more pleasure, it is not the only way. It is quite possible that a small quantity of life, which was more intensely and uniformly present, should give a greater quantity of pleasure than the greatest possible quantity of life that was only just ‘worth living.’ And in that case, on the hedonistic supposition that pleasure is the only thing worth having, we should have to prefer the smaller quantity of life and therefore, according to Mr Spencer, the less evolved conduct. ”

“ Thus the idea that Evolution throws important light on Ethics seems to be due to a double confusion. Our respect for the process is enlisted by the representation of it as the Law of Nature. But, on the other hand, our respect for Laws of Nature would be speedily diminished, did we not imagine that this desirable process was one of them. To suppose that a Law of Nature is therefore respectable, is to commit the naturalistic fallacy; but no one, probably, would be tempted to commit it, unless something which is respectable, were represented as a Law of Nature. ”

“ Now let us examine this contention in its general form. It is obvious, in the first place, that we cannot say that everything natural is good, except perhaps in virtue of some metaphysical theory, such as I shall deal with later. If everything natural is equally good, then certainly Ethics, as it is ordinarily understood, disappears; for nothing is more certain, from an ethical point of view, than that some things are bad and others good; the object of Ethics is, indeed, in chief part, to give you general rules whereby you may avoid the one and secure the other. ”

“ It can only rest on a confused belief that somehow the good simply means the side on which Nature is working. And it thus involves another confused belief which is very marked in Mr Spencer’s whole treatment of Evolution. For, after all, is Evolution the side on which Nature is working? In the sense, which Mr Spencer gives to the term, and in any sense in which it can be regarded as a fact that the more evolved is higher, Evolution denotes only a temporary historical process. ”

“ That things will permanently continue to evolve in the future, or that they have always evolved in the past, we have not the smallest reason to believe. For Evolution does not, in this sense, denote a natural law, like the law of gravity. Darwin’s theory of natural selection does indeed state a natural law: it states that, given certain conditions, certain results will always happen. But Evolution, as Mr Spencer understands it and as it is commonly understood, denotes something very different. ”

“ We shall look in vain for any attempt to shew that ‘ethical sanction’ is in proportion to ‘evolution,’ or that it is the ‘highest’ type of being which displays the most evolved conduct; yet Mr Spencer concludes that this is the case. It is only fair to assume that he is not sufficiently conscious how much these propositions stand in need of proof—what a very different thing is being ‘more evolved’ from being ‘higher’ or ‘better.’ It may, of course, be true that what is more evolved is also higher and better. ”

“ Precisely the same natural laws—Darwin’s, for instance—would under other conditions render inevitable not Evolution—not a development from lower to higher—but the converse process, which has been called Involution. Yet Mr Spencer constantly speaks of the process which is exemplified by the development of man as if it had all the augustness of a universal Law of Nature: whereas we have no reason to believe it other than a temporary accident, requiring not only certain universal natural laws, but also the existence of a certain state of things at a certain time. ”

“ If we consider whether any object is of such a nature that it may be said to exist now, to have existed, or to be about to exist, then we may know that that object is a natural object, and that nothing, of which this is not true, is a natural object. ”

“ The name then is perfectly general; for, no matter what the something is that good is held to mean, the theory is still Naturalism. Whether good be defined as yellow or green or blue, as loud or soft, as round or square, as sweet or bitter, as productive of life or productive of pleasure, as willed or desired or felt: whichever of these or of any other object in the world, good may be held to mean, the theory, which holds it to mean them, will be a naturalistic theory. ”

“ If it were clearly recognised that there is no evidence for supposing Nature to be on the side of the Good, there would probably be less tendency to hold the opinion, which on other grounds is demonstrably false, that no such evidence is required. And if both false opinions were clearly seen to be false, it would be plain that Evolution has very little indeed to say to Ethics. ”

“ But, when a so-called scientific definition of them is attempted, a definition in natural terms, the only one possible is that by way of ‘normal’ and ‘abnormal.’ Now, it is easy to prove that some things commonly thought excellent are abnormal; and it follows that they are diseased. But it does not follow, except by virtue of the naturalistic fallacy, that those things, commonly thought good, are therefore bad. All that has really been shewn is that in some cases there is a conflict between the common judgment that genius is good, and the common judgment that health is good. ”

“ Guided by the truth that as the conduct with which Ethics deals is part of conduct at large, conduct at large must be generally understood before this part can be specially understood; and guided by the further truth that to understand conduct at large we must understand the evolution of conduct; we have been led to see that Ethics has for its subject-matter, that form which universal conduct assumes during the last stages of its evolution. ”

“ To declare it to be obvious is to suggest the naturalistic fallacy: just as in some recent books, a proof that genius is diseased, abnormal, has been used to suggest that genius ought not to be encouraged. ”

“ The notion sometimes lying at the bottom of the minds of preachers of this gospel is that we cannot improve on nature. This notion is certainly true, in the sense that anything we can do, will be a natural product. But that is not what is meant by this phrase; nature is again used to mean a mere part of nature; only this time the part meant is not so much the normal as an arbitrary minimum of what is necessary for life. And when this minimum is recommended as ‘natural’—as the way of life to which Nature points her finger—then the naturalistic fallacy is used. ”

“ This theory, to which Darwin gave the name ‘Natural Selection,’ was also called the theory of survival of the fittest. The natural process which it thus described was called evolution. It was very natural to suppose that evolution meant evolution from what was lower into what was higher; in fact it was observed that at least one species, commonly called higher—the species man—had so survived, and among men again it was supposed that the higher races, ourselves for example, had shewn a tendency to survive the lower, such as the North American Indians. ”

“ To argue that a thing is good because it is ‘natural,’ or bad because it is ‘unnatural,’ in these common senses of the term, is therefore certainly fallacious; and yet such arguments are very frequently used. ”

“ But the above discussion should have made it plain that, if what we want from an ethical philosopher is a scientific and systematic Ethics, not merely an Ethics professedly ‘based on science’; if what we want is a clear discussion of the fundamental principles of Ethics, and a statement of the ultimate reasons why one way of acting should be considered better than another—then Mr Spencer’s ‘Data of Ethics’ is immeasurably far from satisfying these demands. ”

“ Nature does indeed set limits to what is possible; she does control the means we have at our disposal for obtaining what is good; and of this fact, practical Ethics, as we shall see later, must certainly take account: but when she is supposed to have a preference for what is necessary, what is necessary means only what is necessary to obtain a certain end, presupposed as the highest good; and what the highest good is Nature cannot determine. ”

“ We can kill them more easily than they can kill us. The doctrine of evolution was then represented as an explanation of how the higher species survives the lower. Spencer, for example, constantly uses ‘more evolved’ as equivalent to ‘higher.’ But it is to be noted that this forms no part of Darwin’s scientific theory. That theory will explain, equally well, how by an alteration in the environment (the gradual cooling of the earth, for example) , quite a different species from man, a species which we think infinitely lower, might survive us. ”

“ We cannot assume that, because evolution is progress on the whole, therefore every point in which the more evolved differs from the less is a point in which it is better than the less. A simple consideration of the course of evolution will therefore, on this view, by no means suffice to inform us of the course we ought to pursue. ”

“ But they do not commonly pretend to give a systematic theory of Ethics. Among attempts to systematise an appeal to nature, that which is now most prevalent is to be found in the application to ethical questions of the term ‘Evolution’—in the ethical doctrines which have been called ‘Evolutionistic.’ These doctrines are those which maintain that the course of ‘evolution,’ while it shews us the direction in which we are developing, thereby and for that reason shews us the direction in which we ought to develop. Writers, who maintain such a doctrine, are at present very numerous and very popular ”

“ The phrase seems to point to a vague notion that there is some such thing as natural good; to a belief that Nature may be said to fix and decide what shall be good, just as she fixes and decides what shall exist. For instance, it may be supposed that ‘health’ is susceptible of a natural definition, that Nature has fixed what health shall be: and health, it may be said, is obviously good; hence in this case Nature has decided the matter; we have only to go to her and ask her what health is, and we shall know what is good: we shall have based an ethics upon science. ”

“ Against this position I wish only to point out that though the performance of certain acts, not in themselves desirable, may be excused as necessary means to the preservation of life, that is no reason for praising them, or advising us to limit ourselves to those simple actions which are necessary, if it is possible for us to improve our condition even at the expense of of doing what is in this sense unnecessary. ”

“ When therefore we are told that health is natural, we may presume that what is meant is that it is normal; and that when we are told to pursue health as a natural end, what is implied is that the normal must be good. ”

“ Why should we suppose that what is merely necessary to life is ipso facto better than what is necessary to the study of metaphysics, useless as that study may appear? It may be that life is only worth living, because it enables us to study metaphysics—is a necessary means thereto. The fallacy of this argument from nature has been discovered as long ago as Lucian. ”

“ We must not, therefore, be frightened by the assertion that a thing is natural into the admission that it is good; good does not, by definition, mean anything that is natural; and it is therefore always an open question whether anything that is natural is good. ”

“ It is, I think, obvious in the first place, that not all that is good is normal; that, on the contrary, the abnormal is often better than the normal: peculiar excellence, as well as peculiar viciousness, must obviously be not normal but abnormal. ”

“ For I cannot hope to recommend the doctrine that things which are good do not owe their goodness to their common possession of any other property, without a criticism of the main doctrines, opposed to this, whose power to recommend themselves is proved by their wide prevalence.
25. The theories I propose to discuss may be conveniently divided into two groups. The naturalistic fallacy always implies that when we think ‘This is good,’ what we are thinking is that the thing in question bears a definite relation to some one other thing. ”

“ The modern vogue of ‘Evolution’ is chiefly owing to Darwin’s investigations as to the origin of species. Darwin formed a strictly biological hypothesis as to the manner in which certain forms of animal life became established, while others died out and disappeared. His theory was that this might be accounted for, partly at least, in the following way. ”

“ That which reasoning would fairly lead a man to choose, cannot be had by creatures that do not reason, simply because they are so stupid. If Prometheus or some other god had given each of them the intelligence of a man, then they would not have lived in deserts and mountains nor fed on one another. ”
