Man is embedded in nature.

The cloning of humans is on most of the lists of things to worry about from Science, along with behaviour control, genetic engineering, transplanted heads, computer poetry and the unrestrained growth of plastic flowers.

The greatest of all the accomplishments of 20th century science has been the discovery of human ignorance

We habitually engage in meddling with nature. Until this century most of this meddling was good. Witness the preservation of the European countryside. But since then we've smoked it up and littered it and dumped too much in too many waters. I don't think it's our privilege to behave this way.

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.'

Science is founded on uncertainty. Each time we learn something new and surprising, the astonishment comes with the realization that we were wrong before.

We are educated to be amazed by the infinite variety of life forms in nature. We are, I believe, only at the beginning of being flabbergasted by its unity.
