C.S. Lewis pointed out that even our ability to reason and think rationally would be called into question if atheistic evolution were true:
“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 thought processes are mere accidents - the accidental by-product of the movement of atoms. And this holds for the materialists and astronomers as well as for anyone else's. But if their thoughts — i.e. of Materialism — 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 a correct account of all the other accidents.”
Phillip Johnson, law professor at
“Are our thoughts ‘nothing but’ the products of chemical reactions in the brain, and did our thinking abilities originate for no reason other than their utility in allowing our DNA to reproduce itself? Even scientific materialists have a hard time believing that. For one thing, materialism applied to the mind undermines the validity of all reasoning, including one’s own. If our theories are products of chemical reactions [rather than from our soul or spirit, as evolutionists would say], how can we know whether our theories are true? Perhaps [evolutionist] Richard Dawkins believes in Darwinism only because he has a certain chemical in his brain, and if his belief be changed by somehow inserting a different chemical.”
To get this into layman’s terms, I will let the philosopher J. P. Moreland, from his debate with renowned atheist Kai Nielson, explain it.
“Suppose you were driving on a train and you saw a sign on the hillside that said, ‘
C. S. Lewis finishes his thought from above:
“It’s like expecting that the accidental shape taken by the splash when you upset a milk-jug should give you a correct account of how the jug was made and why it was upset.”
