C.S. Lewis on materialistic thoughts

Thought this was interesting...‘If the solar system was brought about by an accidental collision, then the appearance of organic life on this planet was also an accident, and the whole evolution of Man was an accident too. If so, then all our present thoughts are mere accidents the accidental by-product of the movement of atoms. And this holds for the thoughts of the materialists and astronomers as well as for anyone else’s. But if their thoughts i.e. of materialism and astronomy are merely accidental by-products, why should we believe them to be true? I see no reason for believing that one accident should be able to give me a correct account of all the other accidents. It’s like expecting that the accidental shape taken by the splash when you upset a milkjug should give you a correct account of how the jug was made and why it was upset.’C.S. Lewis (1898—1963), The Business of Heaven,
Fount Paperbacks, U.K., p. 97, 1984.
