Isn't God just wishful thinking?

Whether we wish God to exist has no bearing on whether he does - a belief's psychological appeal cannot settle its truth. Sigmund Freud pressed the charge hardest, calling God a projection of our longing for a protective father; it is fair to grant that comfort can masquerade as conviction, but noticing that danger is not yet an argument that God is unreal.

But pressed into an argument about whether God actually exists, the wishful-thinking charge quietly commits what philosophers call the genetic fallacy - judging a belief true or false by where it came from rather than by the evidence. Wanting something to be true tells you nothing about whether it is. And crucially, this cuts both ways: a person could just as easily want God not to exist - to be free of accountability or judgment - and that desire would say nothing either. If motives settled truth, atheism would be as vulnerable to the charge as belief. Desire simply is not evidence, in any direction.

There is even a gentler flip side, associated with C. S. Lewis. Our deepest, restless longing - a yearning no earthly thing quite satisfies - might itself be a clue: creatures are generally born with desires that correspond to something real. But this is worth stating modestly. It is at most a suggestive pointer, not a proof, and there is a serious rival account on which such longings are byproducts of evolution. So the honest position is symmetrical: wishful thinking cannot settle the question against God any more than for him. The real work is done not by wishes but by evidence and argument - which is where the conversation should go next.
