The duty of thinking, therefore, is now recognised by the Church--it was not formerly. But what will be the result of this thinking? In his book, The Hearts of Men, Mr. Fielding tells us that "no man has ever sat down calmly unbiassed to reason out his religion, and not ended by rejecting it." Mr. Fielding adds: "The great men, who have been always religious, do not invalidate what I say.... There is no assumption more fallacious than that, because a man is a keen reasoner on one subject, he is also on another. Men who are strictly religious, who believe in their faith, whatever their faith may be, consider it above proof, beyond argument.... It is emotion, not reason; feeling, not induction." (The Hearts of Men, pp. 142-3.) Does not this deep and sympathetic writer furnish us with a true picture of men's hearts? What if, after exercising their privileges of rational thought and common sense, the majority of men find that Christianity no longer gives them either intellectual satisfaction or moral support? What if they finally arrive at the conclusion that Christianity and all supernatural beliefs are but the survival of primitive superstitions which can no longer bear the light of modern knowledge? These are the grave questions which now confront us. A man may enter, and generally does enter, upon his inquiry biassed in favour of religious belief of some kind. He approaches the subject in a reverent frame of mind. In his private prayers to his God he does not neglect to ask for heavenly guidance. He evinces precisely the spirit which a divine would consider becoming. But as his inquiry proceeds there comes a time when his religious bias disappears--when he can no longer feel what he could honestly call reverence. He discovers that what he thought was known, and had actually been revealed, is unknown. How can he believe in and worship the Unknown? More than ever he feels his own insignificance and ignorance; but the feeling thus excited, while akin to awe, is divested of reverence. Pursuing his search far enough, he succeeds in extricating himself from a quagmire of demonstrably false superstitions. Finally he reaches solid ground, and builds his life upon it. Unfortunately, many never pursue their inquiry up to this stage; they become fearful, or they give it up as a hopeless entanglement, or they find they have not the requisite leisure. Perhaps, therefore, the information gained by one of the more fortunate may be of some little service to others. It will be my endeavour to set forth in this book not only the destructive, but also the constructive, results of a search for truth. P. V. January, 1906. PREFACE TO SECOND EDITION
