The worst result of popular evolutionism has been this. It has substituted the Beast for the Devil. It has made us think that our enemy is what they call our "lower nature", which means our mere lusts and appetites, things entirely innocent in themselves. Pigs are not corrupted with Imperialism. Tigers have no spiritual pride. Whales never sneer. Crocodiles are not in the least hypocritical. The worst sins of all are the purely spiritual sins. You may move upwards, working out the brute, and not work them out in the least. Indeed, you may work them in. The less beastly you grow, the more bad you may grow.
