this is, in fact, all that Mr Spencer has attempted to prove in the two chapters concerned. Yet he tells us that one of the things it has proved is that conduct gains ethical sanction in proportion as it displays certain characteristics. What he has tried to prove is only that, in proportion as it displays those characteristics, it is more evolved. It is plain, then, that Mr Spencer identifies the gaining of ethical sanction with the being more evolved: this follows strictly from his words. But Mr Spencer’s language is extremely loose; and we shall presently see that he seems to regard the view it here implies as false. We cannot, therefore, take it as Mr Spencer’s definite view that ‘better’ means nothing but ‘more evolved’; or even that what is ‘more evolved’ is therefore ‘better.’ But we are entitled to urge that he is influenced by these views, and therefore by the naturalistic fallacy. It is only by the assumption of such influence that we can explain his confusion as to what he has really proved, and the absence of any attempt to prove, what he says he has proved, that conduct which is more evolved is better. 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. But Mr Spencer does not seem aware that to assert the one is in any case not the same thing as to assert the other. He argues at length that certain kinds of conduct are ‘more evolved,’ and then informs us that he has proved them to gain ethical sanction in proportion, without any warning that he has omitted the most essential step in such a proof. Surely this is sufficient evidence that he does not see how essential that step is.
32. Whatever be the degree of Mr Spencer’s own guilt, what has just been said will serve to illustrate the kind of fallacy which is constantly committed by those who profess to ‘base’ Ethics on Evolution. But we must hasten to add
