There is, therefore, about all complete conviction a kind of huge helplessness. The belief is so big that it takes a long time to get it into action. And this hesitation chiefly arises, oddly enough, from an indifference about where one should begin. All roads lead to Rome; which is one reason why many people never get there. In the case of this defence of the Christian conviction I confess that I would as soon begin the argument with one thing as another; I would begin it with a turnip or a taximeter cab. But if I am to be at all careful about making my meaning clear, it will, I think, be wiser to continue the current arguments of the last chapter, which was concerned to urge the first of these mystical coincidences, or rather ratifications. All I had hitherto heard of Christian theology had alienated me from it. I was a pagan at the age of twelve, and a complete agnostic by the age of sixteen; and I cannot understand any one passing the age of seventeen without having asked himself so simple a question. I did, indeed, retain a cloudy reverence for a cosmic deity and a great historical interest in the Founder of Christianity. But I certainly regarded Him as a man; though perhaps I thought that, even in that point, He had an advantage over some of His modern critics. I read the scientific and sceptical literature of my time--all of it, at least, that I could find written in English and lying about; and I read nothing else; I mean I read nothing else on any other note of philosophy. The penny dreadfuls which I also read were indeed in a healthy and heroic tradition of Christianity; but I did not know this at the time. I never read a line of Christian apologetics. I read as little as I can of them now. It was Huxley and Herbert Spencer and Bradlaugh who brought me back to orthodox theology. They sowed in my mind my first wild doubts of doubt. Our grandmothers were quite right when they said that Tom Paine and the free-thinkers unsettled the mind. They do. They unsettled mine horribly. The rationalist made me question whether reason was of any use whatever; and when I had finished Herbert Spencer I had got as far as doubting (for the first time) whether evolution had occurred at all. As I laid down the last of Colonel Ingersoll's atheistic lectures the dreadful thought broke across my mind, "Almost thou persuadest me to be a Christian." I was in a desperate way.
