said and done, it was English and Scotch writers, and not Kant, who introduced 'the critical method' into philosophy, the one method fitted to make philosophy a study worthy of serious men. For what seriousness can possibly remain in debating philosophic propositions that will never make an appreciable difference to us in action? And what could it matter, if all propositions were practically indifferent, which of them we should agree to call true or which false?
An American philosopher of eminent originality, Mr. Charles Sanders Peirce, has rendered thought a service by disentangling from the particulars of its application the principle by which these men were instinctively guided, and by singling it out as fundamental and giving to it a Greek name. He calls it the principle of pragmatism, and he defends it somewhat as follows:[1]—
Thought in movement has for its only conceivable motive the attainment of belief, or thought at rest. Only when our thought about a subject has found its rest in belief can our action on the subject firmly and safely begin. Beliefs, in short, are rules for action; and the whole function of thinking is but one step in the production of active habits. If there were any part of a thought that made no difference in the thought's practical consequences, then that part would be no proper element of the thought's significance. To develop a thought's meaning we need therefore only determine what conduct it is fitted to produce; that conduct is for us its sole significance; and the tangible fact at the root of all our thought-distinctions is that there is no one of them so fine as to consist in anything but a possible difference of practice.
