The universe never did make sense; I suspect it was built on government contract.

Political tags - such as royalist, communist, democrat, populist, fascist, liberal, conservative, and so forth - are never basic criteria. The human race divides politically into those who want people to be controlled and those who have no such desire.

It is a truism that almost any sect, cult, or religion will legislate its creed into law if it acquires the political power to do so.

Being right too soon is socially unacceptable.

In political science, public support doesn't have a reverse gear. It always goes forward.

The most pressing ethical question is to make sure that everything you do from a scientific standpoint is done for the ultimate good and positive issue for the people that you're caring about.

I think there's always been a traditionally apocalyptic side to British science fiction, from H.G. Wells onwards. I mean, most of Wells' stories are potentially apocalyptic in some sense or another.

One of the greatest features of science is that it doesn't matter where you were born, and it doesn't matter what the belief systems of your parents might have been: If you perform the same experiment that someone else did, at a different time and place, you'll get the same result.
