Jesting Pilate by Aldous Huxley
Of the fact that it takes all sorts to make a world I have been aware ever since I could read. But proverbs are always commonplaces until you have personally experienced the truth of them. The newly arrested thief knows that honesty is the best policy with an intensity of conviction which the rest of us can never experience. And to realize that it takes all sorts to make a world one must have seen a certain number of the sorts with one's own eyes. Having seen them and having in this way acquired an intimate realization of the truth of the proverb, one finds it hard to go on complacently believing that one's own opinions, one's own way of life are alone rational and right. This conviction of man's diversity must find its moral expression in the practice of the completest possible tolerance.
