customary and institutional, in which those results find permanent expression. [Sidenote: to be connected by philosophy.] These different ways of looking at the whole subject proceed from points of view whose effects are not confined to ethics, but may be followed out in other lines of investigation. They correspond to ideas which dominate different types of thought and form different philosophical standpoints. The first starts from a teleological conception of human nature, as an organism consciously striving towards its end. The second assimilates ethics to a system of legal enactments, and is connected with the jural conceptions of theology and law. The two last are concerned to show that the subject-matter of ethics are facts which have to be treated by the ordinary inductive and historical methods. These different points of view, however, are to be regarded as complementary rather than as conflicting, although their complete synthesis must be worked out in the region of general philosophy, and not on purely ethical ground. Philosophy has thus to deal with the notions which determine the scope and character of ethical thought; and in this way it must necessarily pass from the purely speculative to the practical point of view. If it is the business of philosophy to bring into rational order the material supplied by experience, cosmical and anthropological, it cannot be without bearing on the function of man as a source of action in the world. The question, What are the ends man is naturally fitted to attain? or--if we prefer so to express it--What are the ends he ought to pursue? is not merely as natural as the question, What can a man know of the world and of himself? But the two questions are inseparably connected. To know man is to know him not only as a thinking but also as an active being; while to solve the problem of the ends of man implies knowledge both of his nature and of the sphere of his activity. [Sidenote: (_b_) Ethics necessary to complete philosophy.] Much distrust is often expressed of metaphysics. But it is not denied that the philosophy--whether metaphysical or not--in which our most comprehensive view of the world finds its reasoned expression, cannot neglect that aspect of things in which man is related to his surroundings as a source of action. Recent ethical literature is itself a proof of this fact. In its speculative developments, both realistic and idealistic, the philosophy of the present day has made the endeavour to connect its conceptions of the world of thought and nature with the ends contemplated as to be realised in the realm of action. Whatever difficulties may be involved in the transition from the "is" to the "ought to be," it is yet implied that the transition requires to be made, not merely in order that human activity may be shown to be rational, but that reason itself may be justified by leaving nothing outside its sphere.
