In Response to C. S. Lewis

C.S. Lewis Reasoning on Atheism

‎"Supposing there was no intelligence behind the universe, no creative mind. In that case, nobody designed my brain for the purpose of thinking. It is merely that when the atoms inside my skull happen, for physical or chemical reasons, to arrange themselves in a certain way, this gives me, as a by-product, the sensation I call thought. But, if so, how can I trust my own thinking to be true? It's like upsetting a milk jug and hoping that the way it splashes itself will give you a map of London. But if I can't trust my own thinking, of course I can't trust the arguments leading to Atheism, and therefore have no reason to be an Atheist, or anything else. Unless I believe in God, I cannot believe in thought: so I can never use thought to disbelieve in God."
—C.S. LewisThe Case for Christianity, p. 32.

Suppose there was an intelligence behind the universe, a creative mind. In that case, something may have designed my brain for the purpose of thinking. 

It is only because the atoms inside my skull are arranged just so that gives me the sensation I call thought. But, if so, how can I trust my thinking to be my own? 

It’s like a machine ever stamping out the same metal parts, never able to vary from its predetermined task. 

But if my thinking is not my own, of course there is no argument, about anything, for I am only what I was made to be, and incapable of being otherwise.

And therefore I cannot believe in God, or anything else. I am incapable that act. I have no reason. I have no thought. Belief ceases to have meaning. 

The point being, something independent of God must exist, some "jug of spilled milk" that has splashed itself into a map of my life, or I am nothing more than a mindless automaton. 

Take THAT, presuppositional apologetics!
