The world is made up of people who never quite get into the first team and who just miss the prizes at the flower show.

To me, being an intellectual doesn't mean knowing about intellectual issues; it means taking pleasure in them.

Science is a very human form of knowledge. We are always at the brink of the known; we always feel forward for what is to be hoped. Every judgment in science stands on the edge of error and is personal. Science is a tribute to what we can know although we are fallible.

The values by which we are to survive are not rules for just and unjust conduct, but are those deeper illuminations in whose light justice and injustice, good and evil, means and ends are seen in fearful sharpness of outline.

There is no absolute knowledge. And those who claim it, whether they are scientists or dogmatists, open the door to tragedy.

We gain our ends only with the laws of nature; we control her only by understanding her laws.

The progress of science is the discovery at each step of a new order which gives unity to what had seemed unlike.
