Man has subdued nature, conquered seas, conquered distance, and is now penetrating space, but he has not yet learned to conquer himself, nor is he even now putting forth comparable effort to subdue and master lingering animal tendencies and passions which, when dominant, may destroy him.
To this day the more conventional biologists suffer from an obsessional fear of anthropomorphism, and even put such words as "hunger" and "fear" between quotes (a literary solecism in any case) when writing about animals. The quotes are a way of saying "I cannot get on without Anthropomorphism, but I am ashamed to be seen with her in public".
I am not basically a conservationist. When the last great whale is slaughtered, as it surely will be, the whales' suffering will be over. This is not the whales' loss, but man's. I am not concerned about the wiping out of a species - this is man's folly - I have only one concern, the suffering which we deliberately inflict upon animals whilst they live.
Agriculture probably required a far greater discipline than did any form of food collecting. Seeds had to be planted at certain seasons, some protection had to be given to the growing plants and animals, harvests had to be reaped, stored and divided. Thus, we might argue that it was neither leisure time nor a sedentary existence but the more rigorous demands associated with an agricultural way of life that led to great cultural changes.
The plow is one of the most ancient and most valuable of man's inventions; but long before he existed the land was in fact regularly plowed, and still continues to be thus plowed by earthworms. It may be doubted whether there are many other animals which have played so important a part in the history of the world, as have these lowly organized creatures.
