“It was long before I could believe that human learning had no clear answer to this question. For a long time it seemed to me, as I listened to the gravity and seriousness wherewith Science affirmed its positions on matters unconnected with the problem of life, that I must have misunderstood something. For a long time I was timid in the presence in learning, and I fancied that the insufficiency of the answers which I received was not its fault, but was owing to my own gross ignorance, but this thing was not a joke or a pastime with me, but the business of my life, and I was at last forced, willy-nilly, to the conclusion that these questions of mine were the only legitimate questions underlying all knowledge, and that it was not I that was in fault in putting them, but science in pretending to have an answer for them.”
