It is likewise obvious that we have here a question as to which every human being has the means of judging equally with the most eminent man of Science, and modern improvement of the methods and instruments of research leaves us just where we always were. The final evidence on the subject every man has within himself, in the most vital facts of his own experience. Into the philosophy of the matter it is neither necessary nor advisable at present to go. In dealing with profound yet elementary questions, regarding which our means of knowledge are thus simple and direct, men are apt to bewilder themselves when they begin to philosophize, and to persuade themselves that they cannot be sure precisely of those things that are most certain. George Borrow is by no means the only one who has tormented himself with doubts as to his own existence.[124] A still larger number have professed to believe themselves mere machines compelled to go like clocks, and to do only what has been predetermined for them. But such beliefs are for the lecture-room or the study only, and in practical life every one behaves as if both he himself and others--especially others--were responsible for their conduct. So common-sense teaches, than which we shall not find a safer guide. "Sir," said the eminently common-sense Dr. Johnson, "we _know_ our will is free; and _there's_ an end on't. All theory is against the freedom of the will; all experience for it.... But, Sir, as to the doctrine of necessity, no man believes it. If a man should give me arguments that I cannot answer to prove that I cannot see; because I cannot answer his arguments, do I believe that I have no eyes?" Thus we find once again that the doctrines which some would force upon us in the name of Science, on whatever they are founded, have no basis of fact, and cannot therefore rightly call themselves scientific.
