and "deeper change" which Mr Stephen holds to be necessary.[109] It is the ambiguity of the subject--or rather its twofold range--which has made the application of evolution to ethics look so obvious, and made a discussion of the easier question frequently do duty for a solution of the more difficult. The ethical writings of the evolutionists, indeed, often confuse the problems of history and theory in a way which presents the same difficulty to the critic as the works of the corresponding school in jurisprudence. In both, the writers seem disinclined fairly to put to themselves the question as to the kind of subjects to which so fruitful a method as that which has fallen into their hands is appropriate: what its conditions are, and whether it has any limits at all. Every one is now familiar with the evils of hypothetical history, and with the iniquity of the proverbial philosophic offence of constructing facts out of one's inner consciousness. The historical jurists deserve no little credit for the thoroughness with which this has been enforced by them; perhaps, too, the same lesson may be learned from the facts of the development of morality. But it may be questioned whether we are not at the present time more apt to confuse fact and theory in the opposite way: whether the science of law is not sometimes lost sight of in the history of legal institutions, and ethics in danger of being identified with the development of moral sentiments and customs. We may naturally expect the theory of evolution to throw light on such questions as the growth of moral feelings and ideas, and of the customs and institutions in which morality is expressed and embodied. But to show the process morality has passed through in the individual mind and in society still leaves the question as to the end of conduct unanswered. It is necessary, therefore, to keep clearly before us the distinction between the historical and the ethical problem, if we would successfully attack the subject of the bearing of the theory of evolution on this fundamental question of ethics. To the theory of evolution we are indebted for the opening up of a new field of investigation--the historical treatment of conduct. But it is one thing to describe the way in which men have acted in the past: to determine the end for their action now is quite a different problem; and there is no reason why the distinction should be overlooked. The interest which belongs to the history of morality is not solely nor mainly due to its bearing on questions beyond the historical sphere. That its results will not be without relation--and that of an important kind--to questions of theory may well be expected. But it can only tend to confusion if we treat the development of morality, in the human mind and in society, from a preconceived attitude--dogmatic or agnostic--towards the central problem of ethics. * * * * *
