Free Choice

“[C. S.] Lewis could not go on thinking it over for ever. He realized that some sort of ‘leap of faith’ was necessary to get him over the final hurdle. ‘There must,’ he [Lewis] said, ‘perhaps always be just enough lack of demonstrative certainty to make free choice possible, for what could we do but accept if the Faith were like the multiplication table?’ So he became a Christian.”
