And what of Nature itself, you say--that callous and cruel engine, red in tooth and fang? Well, it is not so much of an engine as you think. As for "red in tooth and fang," whenever I hear the phrase or its intellectual echoes I know that some passer-by has been getting life from books. It is true that there are grim arrangements. Beware of judging them by whatever human values are in style. As well expect Nature to answer to your human values as to come into your house and sit in a chair. The economy of nature, its checks and balances, its measurements of competing life--all this is its great marvel and has an ethic of its own. Live in Nature, and you will soon see that for all its non-human rhythm, it is no cave of pain.
