So if you have to live amongst men, you must allow everyone the right to exist in accordance with the character he has, whatever it turns out to be: and all you should strive to do is to make use of this character in such a way as its kind and nature permit, rather than to hope for any alteration in it, or to condemn it off-hand for what it is. This is the true sense of the maxim--Live and let live. That, however, is a task which is difficult in proportion as it is right; and he is a happy man who can once for all avoid having to do with a great many of his fellow creatures.
Arthur Schopenhauer, Parerga and Paralipomena
