Homer L. Twigg IV

And it is right that it should be so. When we call something a mystery, we mean that we cannot iron out the difficulties about understanding it and demonstrate once for all that it is perfectly possible. Nevertheless we do not believe that contradictions and absurdities can be true, or that anything logically demonstrable from things known can be false. And so we believe that there are answers to supposed proofs of absurdity, whether or not we are clever enough to find them.
