The reason for insisting on this fact is not failure to appreciate the distinctive value of knowledge when once it comes into existence. This value is so immense it may be called unique. The aim of the discussion is not to subordinate knowing to some hard, prosaic utilitarian end. The reason for insistence upon the derivative position of knowing in activity, roots in a sense for fact, and in a realization that the doctrine of a separate original power and impulse of knowledge cuts knowledge off from other phases of human nature, and results in its non-natural treatment. The isolation of intellectual disposition from concrete empirical facts of biological impulse and habit-formation entails a denial of the continuity of mind with nature. Aristotle asserted that the faculty of pure knowing enters a man from without as through a door. Many since his day have asserted that knowing and doing have no intrinsic connection with each other. Reason is asserted to have no responsibility to experience; conscience is said to be a sublime oracle independent of education and social influences. All of these views follow naturally from a failure to recognize that all knowing, judgment, belief represent an acquired result of the workings of natural impulses in connection with environment. Upon the ethical side, as has been intimated, the matter at issue concerns the nature of conscience. Conscience has been asserted by orthodox moralists to be unique in origin and subject-matter. The same view is embodied by implication in all those popular methods of moral training which attempt to fix rigid authoritative notions of right and wrong by disconnecting moral judgments from the aids and tests which are used in other forms of knowledge. Thus it has been asserted that conscience is an original faculty of illumination which (if it has not been dimmed by indulgence in sin) shines upon moral truths and objects and reveals them without effort for precisely what they are. Those who hold this view differ enormously among themselves as to the nature of the objects of conscience. Some hold them to be general principles, others individual acts, others the order of worth among motives, others the sense of duty in general, others the unqualified authority of right. Still others carry the implied logic of authority to conclusion, and identify knowledge of moral truths with a divine supernatural revelation of a code of commandments.
