“If the life of natural things, millions of years old, does not seem sacred to us, then what can be sacred? Human vanity alone? Contempt for the natural world is contempt for life. The domination of nature leads to the domination of human nature. Anything becomes permissible. We return once more to the nightmare cultures of Hitler, Stalin, King Philip II, Montezuma, Caligula, Heliogabalus, Herod, the Pharaohs; Christ sacrificed himself in vain.”
