Choose a topic from Vol 3:
I myself believe in free will, yet I deny absolutely that I must inevitably come to any absurd conclusion as a consequence of my conviction.
Your trouble is a confusion of ideas. Before discussing a subject it is essential to get very clear ideas on that subject, and to know the precise sense of the terms you use. Otherwise, ambiguities and fallacies are bound to result. I know exactly what you have in mind. But you express yourself very badly. What you have in mind cannot be denied. But what you say can be denied. For example, if you drove a motor car at sixty miles an hour, you would know that that car could do sixty miles an hour. You would not be free to believe otherwise. But ifI took that same car out and drove it at eighty-five miles an hour, and came back and told you I had done so, you would be free to believe what you liked about it. You have only my word for it. You could choose to believe me. Or you could choose to doubt my accuracy of observation, or my veracity. Not having experimental knowledge for yourself, it would not be manifestly wrong and absurd for you to believe whatever you liked. You see you have used the word believe without any regard for the motives of belief or for the degrees of certainty in our knowledge.
It is certain that so long as he rejects a thing as untrue, he cannot believe it. But he can cease to reject as untrue what he at one time thought to be untrue on discovering that he has no real proof that it is untrue, either because his former judgment was based on inadequate knowledge, or because there was a fault in his process of reasoning.
Taking your proposition as it stands, I must confess that I would have a good deal of difficulty in believing it myself. If, however, a man said to me, "The God Who created this universe arranged that a huge fish (not necessarily a whale) should swallow a man, and by His divine power God kept that man alive inside the fish," I would certainly agree that it was not impossible for an omnipotent God to do such a thing. I could believe it, though I would not believe it actually occurred without a convincing authority for doing so.
At one time men could not believe that a person in England could speak to another person in America. But we, who know of radio transmission, find no difficulty in believing it. For the factor rendering it possible is known to us, whereas it was unknown to them. They could not believe it so long as the factor of radio transmission was omitted from the proposition. Now, if you restrict your proposition to a man, a whale, and the man's living inside the whale for three days, omitting all reference to God's intervention, your difficulties do not surprise me. But will you say that God Himself could not cause such an event to happen? I am not asking you to believe that it did happen. I only suggest that, since God could do it, you could believe it if He did do it.
There are other forces which could alter your beliefs, despite your assertion to the contrary. I knew a girl who believed absolutely in the rectitude of a man she loved, despite evidence to the contrary clear to all others who knew him. After two years her love faded, and her belief changed. A human being's beliefs are often dictated by psychological factors and this is because the human will is free, making possible the will to believe in those who desire to believe. And where the Christian religion is concerned, the will to believe involves no conflict with reason. Belief is, in fact, the reasonable choice.
