"When I reached intellectual maturity, and began to ask myself whether I was an atheist, a theist or a pantheist, a materialist or an idealist, a Christian or a freethinker, I found that the more I learned and reflected, the less ready was the answer; until, at last, I came to the conclusion that I had neither art nor part with any of these denominations, except the last. The one thing on which most of these good people were agreed was the one thing in which I differed from them. They were quite sure they had attained a certain "gnosis" — had more or less successfully, solved the problem of existence; while I was quite sure that I had not, and had a pretty strong conviction that the problem was insoluble."
