This general view of the logical constitution of the moral experience may suggest a comparison with the fundamental doctrine of the British Intellectualist school. The Intellectualist writers were very largely guided in their expositions by the desire of refuting on the one hand Hobbes and on the other Shaftesbury and Hutcheson. Against Hobbes they wished to establish the obligatory character of the moral law entirely apart from sanction or enactment by political authority. Against the Sentimentalists they wished to vindicate its objectivity and permanence. This twofold purpose they accomplished by holding that the morality of conduct lies in its conformity to the "objective nature of things," the knowledge of which, in its moral aspects, is logically deducible from certain moral axioms, self-evident like those of mathematics. Now this mathematical analogy is the key to the whole position of the Intellectualist writers. By so conceiving the nature of knowledge these men seriously weakened their strong general position. Mathematics is just that species of knowledge which is most remote from and apparently independent of any reference to conduct, and the Intellectualists, by choosing it as their ideal, were thereby rendered incapable of explaining the obligatoriness of the moral law. An adequate psychology of knowledge would have obviated this difficulty in their system. The occasion for economic judgment is given, as we have seen, in a conflict between ends not incompatible, in view of any ascertainable conditions of the agent's nature as an empirical self, but inhibitory of each other in view of what we have described as conditions external to the agent. Thus the lawyer in our illustration found his plan of compromise thwarted by the existence of such sociological conditions as would make the practice of his profession, in the manner intended, impossible, and so cut off his income. Similarly the peasant in a European country finds that (for reasons which, more probably, he does not understand) he can no longer earn a living in the accustomed way, and emigrates to a country in which his capital and his physical energies may be more profitably employed. So also in the everyday lives of all of us ends and interests quite disparate, so far as any relation to each other through our psychical capacities is concerned, stand very frequently in opposition, nevertheless, and calling for adjustment. We must make a choice between amusement or intellectual pursuits or the means of æsthetic culture, on the one hand, and the common necessaries of life on the other, and the difficulty of the situation lies just in absence of any sort of "spiritual affinity" between these ends. There is no necessary ratio between the satisfaction of the common needs of life and the cultivation of the higher faculties--no ratio for which the individual can ever find a sanction in the constitution of his empirical self through the direct method of ethical valuation.
