In C.S. Lewis’ book, The Great Divorce, the fat, cultured ghost is conversing with Dick, one of the “Bright People.” Dick is attempting to explain the truth about where the ghost has been. The ghost argues not only that all truth is relative, but also that endlessly searching for truth is of more value than ever actually finding it.

Ah, but we must all interpret those beautiful words in our own way! For me there is no such thing as a final answer. The free wind of inquiry must always continue to blow through the mind, must it not? “Prove all things” . . . to travel hopefully is better than to arrive.
