Force and mind are opposites; morality ends where a gun begins.

For centuries, the mystics of spirit had existed by running a protection racket - by making life on earth unbearable, then charging you for consolation and relief, by forbidding all the virtues that make existence possible, then riding on the shoulders of your guilt, by declaring production and joy to be sins, then collecting blackmail from the sinners.

An attempt to achieve the good by force is like an attempt to provide a man with a picture gallery at the price of cutting out his eyes.

A man doesn't borrow pieces of his body. A building doesn't borrow hunks of its soul. Its maker gives it the soul and every wall, window and stairway to express it.
