So much is said about "scientific doubt" in these days that it is well to remember that doubts as to the truth of the Christian belief are not caused alone by purely scientific difficulties of faith. Carlyle refused to accept Darwin's theories. His temperament was strongly inclined to a stern Puritanical piety, and his whole nature was antipathetic to science. Yet he did not think it possible that "educated honest men could profess much longer to believe in historical Christianity." Renan, a profound scholar in Oriental languages, shows, in his famous work, The Life of Jesus, that, while keenly appreciative of all that was beautiful in the life and teaching of Jesus, he was forced, by his study of the Scriptures [19] in the original, to the conclusion that the miraculous part of the narrative had no historical foundation. Leo Tolstoi, the helper of the helpless, whose voice is ever raised in the cause of universal love and peace, vainly sought an answer to religious doubts, and finally renounced Christian dogmas, building up a religion of his own. Numerous instances could be given showing that well-known and pious-minded thinkers have rejected Christianity on grounds other than scientific. And this diversity in the reasons for negation further tends to strengthen those suspicions regarding our faith which it is now the apologist's task to dispel. A significant circumstance is the far more tolerant attitude of the better-informed clergy towards the unbeliever. There still remain persons of the Dr. Torrey and the Rev. J. Morgan Gibbon [20] type, ready to vilify the agnostic; but their number is rapidly on the decrease. The clergy, as a whole, are more tolerant now than many of the pious laity. Why is this? Is it not because they are beginning to appreciate the perplexities of faith, and to learn that agnostics as a body can be, and are, good men? Under certain conditions they themselves have severe wrestlings with the dictates of reason, and it is only by prayer [21] and occupying their minds in their work that they are able to dispel dark doubts. They will tell you that a faith such as theirs, and such as they hope you will attain after emergence from doubt, is a real faith, with which the faith of the ordinary person, accepting everything on trust, is not to be compared.
