Now it appears that this view of human will and conduct as subject to definite law, is indeed recognised and acted upon by the very people who oppose it when stated in the abstract as a general principle, and who then complain that it annihilates man's free will, destroys his sense of personal responsibility, and degrades him to a soulless machine. He who will say these things will nevertheless pass much of his own life in studying the motives which lead to human action, seeking to attain his wishes through them, framing in his mind theories of personal character, reckoning what are likely to be the effects of new combinations, and giving to his reasoning the crowning character of true scientific enquiry, by taking it for granted that in so far as his calculation turns out wrong, either his evidence must have been false or incomplete, or his judgment upon it unsound. Such a one will sum up the experience of years spent in complex relations with society, by declaring his persuasion that there is a reason for everything in life, and that where events look unaccountable, the rule is to wait and watch in hope that the key to the problem may some day be found. This man's observation may have been as narrow as his inferences are crude and prejudiced, but nevertheless he has been an inductive philosopher 'more than forty years without knowing it.' He has practically acknowledged definite laws of human thought and action, and has simply thrown out of account in his own studies of life the whole fabric of motiveless will and uncaused spontaneity. It is assumed here that they should be just so thrown out of account in wider studies, and that the true philosophy of history lies in extending and improving the methods of the plain people who form their judgments upon facts, and check them upon new facts. Whether the doctrine be wholly or but partly true, it accepts the very condition under which we search for new knowledge in the lessons of experience, and in a word the whole course of our rational life is based upon it.
'One event is always the son of another, and we must
