To love involves trusting the beloved beyond the evidence, even against much evidence. No man is our friend who believes in our good intentions only when they are proved. No man is our friend who will not be very slow to accept evidence against them. Such confidence, between one man and another, is in fact almost universally praised as a moral beauty, not blamed as a logical error. And the suspicious man is blamed for a meanness of character, not admired for the excellence of his logic.
C. S. Lewis
