Graham Greene said this quote

Wouldn't we all do better not trying to understand, accepting the fact that no human being will ever understand another, not a wife a husband, a lover a mistress, nor a parent a child? Perhaps that's why men have invented God -- a being capable of understanding. Perhaps if I wanted to be understood or to understand I would bam-boozle myself into belief, but I am a reporter; God exists only for leader-writers.
