What is a scientist after all? It is a curious man looking through a keyhole, the keyhole of nature, trying to know what’s going on.

If we were logical, the future would be bleak, indeed.

The happiness of the bee and the dolphin is to exist. For man it is to know that and to wonder at it.

Mankind has probably done more damage to the Earth in the 20th century than in all of previous human history.

Farming as we do it is hunting, and in the sea we act like barbarians.
