I am one of those scientists who feels that it is no longer enough just to get on and do science. We have to devote a significant proportion of our time and resources to defending it from deliberate attack from organised ignorance.

Vanity of science. Knowledge of physical science will not console me for ignorance of morality in time of affliction, but knowledge of morality will always console me for ignorance of physical science.

The enlightenment is under threat. So is reason. So is truth. So is science, especially in the schools of America.

It vexes me when they would constrain science by the authority of the Scriptures, and yet do not consider themselves bound to answer reason and experiment.

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.

Science has not yet mastered prophecy. We predict too much for the next year and yet far too little for the next 10.

Science is always discovering odd scraps of magical wisdom and making a tremendous fuss about its cleverness.

The foundation of empire is art and science. Remove them or degrade them, and the empire is no more. Empire follows art and not vice versa as Englishmen suppose.

Politics is a science. You can demonstrate that you are right and that others are wrong.
