facility of action and of language. Just because this parcelling of the real has been effected in view of the exigencies of practical life, it has not followed the internal lines of the structure of things: for that very reason empiricism cannot satisfy the mind in regard to any of the great problems and, indeed, whenever it becomes fully conscious of its own principle, it refrains from putting them.—Dogmatism discovers and disengages the difficulties to which empiricism is blind; but it really seeks the solution along the very road that empiricism has marked out. It accepts, at the hands of empiricism, phenomena that are separate and discontinuous, and simply endeavours to effect a synthesis of them which, not having been given by intuition, cannot but be arbitrary. In other words, if metaphysic is only a construction, there are several systems of metaphysic equally plausible, which consequently refute each other, and the last word must remain with a critical philosophy, which holds all knowledge to be relative and the ultimate nature of things to be inaccessible to the mind. Such is, in truth, the ordinary course of philosophic thought: we start from what we take to be experience, we attempt various possible arrangements of the fragments which apparently compose it, and when at last we feel bound to acknowledge the fragility of every edifice that we have built, we end by giving up all effort to build. But there is a last enterprise that might be undertaken. It would be to
