56 we shall be able to discover Evolution to be a criterion of it. We shall have to establish a relation between two highly complicated sets of data; and, moreover, if we had once settled what were goods, and what their comparative values, it is extremely unlikely that we should need to call in the aid of Evolution as a criterion of how to get the most. It is plain, then, again, that if this were the only relation imagined to exist between Evolution and Ethics, it could hardly have been thought to justify the assignment of any importance in Ethics to the theory of Evolution. Finally, (3) it may be held that, though Evolution gives us no help in discovering what results of our efforts will be best, it does give some help in discovering what it is possible to attain and what are the means to its attainment. That the theory really may be of service to Ethics in this way cannot be denied. But it is certainly not common to find this humble, ancillary bearing clearly and exclusively assigned to it. In the mere fact, then, that these non-fallacious views of the relation of Evolution to Ethics would give so very little importance to that relation, we have evidence that what is typical in the coupling of the two names is the fallacious view to which I propose to restrict the name ‘Evolutionistic Ethics.’ This is the view that we ought to move in the direction of evolution simply because it is the direction of evolution. That the forces of Nature are working on that side is taken as a presumption that it is the right side. That such a view, apart from metaphysical presuppositions, with which I shall presently deal, is simply fallacious, I have tried to shew. 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
