If we're going to make a politically responsible and a scientifically sensible claim it should not be stop the world exactly where it is because that's not possible. It has to be to decide what kind of world do we as human beings want to live in.

The vulgarization of Darwinism that sees the "struggle for existence" as nothing but the competition for some environmental resource in short supply ignores the large body of evidence about the actual complexity of the relationship between organisms and their resources.

If I ask you who is the most famous scientist who ever lived, or the greatest scientist who ever lived you'll say either Einstein or Newton or something like that because their claims were supposed to apply universally. But the claim of somebody who is studying a particular feature of the evolutionary process like whether it's very fast or very slow, or occurs in steps and so on, that's not a universal claim, that's a rather specialised claim and so you can't claim to great fame and great success.

My general impression about people like Steve Gould and Carl Sagan and so on is that when they disappear as individuals and are no longer appearing on the stage and they are no longer writing, that their lifetime of acknowledgement by the general reading public is not very long... There were many people in the 19th century who were equally famous people who gave working man's lectures, supporters of Darwin, we as scholars know their names but the general public never heard of them.

If I put myself on the side of those who see the world as warming up in a bad way, who see the general march of industrial culture as something undesirable, the one thing I must be beware of doing and which my colleagues on that side don't beware of doing, we must beware of saying we've got to stop changing the environment. There is no 'the' environment which we can change, the world is changing all the time.

Scientists are educated from a very early time and a very early age to believe that the greater scientist is the scientist who makes discoveries or theories that apply to the greatest ambit of things in the world. And if you've only made a very good theory about snails, or a very good theory about some planets but not about the universe as a whole, or about all the history of humankind, then you have in some sense accepted a lower position in the hierarchy of the fame of science as it's taught to you as a young student.
