Is it really true that the argument from first cause is irrational? It seems rational to me.
The principle of sufficient reason states that nothing exists without cause or reason. The universe is incapable of explaining itself.
According to the classic proof:
We can escape from the endless regression only by positing as a sufficient reason for the universe the existence of a being that does not itself need another reason.
According to Andre Comte-Sponville, atheist and Parisian philosopher:
Of the three classical 'proofs' of God's existence this is the only one I find powerful, the one that occasionally makes me vacillate or hesitate. Why? Because contingency is an abyss in which reason loses its bearings. Disorientation, however, does not constitute proof. Why shouldn't reason- our reason- get lost in the universe. ... Indeed how can we be certain that our reason is perfectly rational? Only a God could guarantee us that, and this is just what prevents our reason from proving his existence.
The crux of the cosmological proof is the principle of sufficient reason...Why the universe? Because God. But how do we know there is an order? How do we know reason is right? What makes us think there is no such thing as the absolutely inexplicable? Why should contingency not have the last word- or the final silence? So what, why shouldn't the truth be absurd?

I don't intend to derail the thread, but it seems as though, according to Sponville anyways, that this proof can not be trusted precisely because reason itself can not be trusted in any ultimate or cosmic sense. Our reason, as it may turn out, is not truly rational. It seems, according to Sponville, that the argument from contingency is rational. Reality might not be.
At the very least, is the proof from contingency really "silly" or "stupid" ?
