Well, biology today as I see it has an amiable look - quite different from the 19th-century view that the whole arrangement of nature is hostile, 'red in tooth and claw.' That came about because people misread Darwin's 'survival of the fittest.'

The human mind is not meant to be governed, certainly not by any book of rules yet written; it is supposed to run itself, and we are obliged to follow it along, trying to keep up with it as best we can.

We are built to make mistakes, coded for error.

As a people, we have become obsessed with Health. There is something fundamentally, radically unhealthy about all this. We do not seem to be seeking more exuberance in living as much as staving off failure, putting off dying. We have lost all confidence in the human body.

We are told that the trouble with modern man is that he has been trying to detach himself from nature... In this scenario, Man comes on as a stupendous lethal force, and the Earth is pictured as something delicate, like rising bubbles at the surface of a country pond, or flights of fragile birds.
