Scientists have power by virtue of the respect commanded by the discipline... We live with poets and politicians, preachers and philosophers. All have their ways of knowing, and all are valid in their proper domain. The world is too complex and interesting for one way to hold all the answers.

Any human being is really good at certain things. The problem is that the things you're good at come naturally. And since most people are pretty modest instead of an arrogant S.O.B. like me, what comes naturally, you don't see as a special skill. It's just you. It's what you've always done.

Can I pay any higher tribute to a man [George Gaylord Simpson] than to state that his work both established a profession and sowed the seeds for its own revision? If Simpson had reached final truth, he either would have been a priest or would have chosen a dull profession. The history of life cannot be a dull profession.

If I have any insight at all to contribute it is this: find out what you are really good at and stick to it.
