When we subject what are called religious truths to the same tests by which we determine scientific or historical truths, we discover that they are not truths at all; they are only opinions. Any statement which snaps under the strain of reason is unworthy of credence. But it is claimed that religious truth is discovered by intuition and not by investigation. The believer, it is claimed, feels in his own soul--he has the witness of the spirit, that the Bible is infallible, and that Jesus is the Savior of man. The Christian does not have to look into the arguments for or against his religion, it is said, before he makes up his mind; he knows by an inward assurance; he has proved it to his own deepermost being that Jesus is real and that he is the only Savior. But what is that but another kind of argument? The argument is quite inadequate to inspire assurance, as you will presently see, but it is an argument nevertheless. To say that we must believe and not reason is a kind of reasoning, This device of reasoning against reasoning is resorted to by people who have been compelled by modern thought to give up, one after another, the strongholds of their position. They run under shelter of what they call faith, or the "inward witness of the spirit," or the intuitive argument, hoping thereby to escape the enemy's fire, if I may use so objectionable a phrase. What is called faith, then, or an intuitive spiritual assurance, is a species of reasoning; let its worth be tested honestly. In the first place, faith or the intuitive argument would prove too much. If Jesus is real, notwithstanding that there is no reliable historical data to warrant the belief, because the believer feels in his own soul that He is real and divine, I answer that, the same mode of reasoning--and let us not forget, it is a kind of _reasoning_--would prove Mohammed a divine savior, and the wooden idol of the savage a god. The African Bushman trembles before an image, because he feels in his own soul that the thing is real. Does that make it real? The Moslem cries unto Mohammed, because he believes in his innermost heart that Mohammed is near and can hear him. He will risk his life on that assurance. To quote to him history and science to prove that Mohammed is dead and unable to save, would be of no avail, for he has the witness of the spirit in him, an intuitive assurance, that the great prophet sits on the right hand of Allah. An argument which proves too much, proves nothing.
