A man full of faith is simply one who has lost (or never had) the capacity for clear and realistic thought. He is not a mere ass; he is actually ill. Worse, he is incurable, for disappointment, being essentially an objective phenomenon, cannot permanently affect his subjective infirmity. His faith takes on the virulence of a chronic infection. What he usually says, in substance, is this: "Let us trust in god, who has always fooled us in the past."

~ H. L. Mencken
