A goodly number of scientists are not only narrow-minded and dull, but also just stupid.

Science moves with the spirit of an adventure characterized both by youthful arrogance and by the belief that the truth, once found, would be simple as well as pretty.

There is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so.

We're not all equal, it's simply not true. That isn't science.

I'm basically a libertarian. I don't want to restrict anyone from doing anything unless it's going to harm me. I don't want [to] pass a law stopping someone from smoking. It's just too dangerous. You lose the concept of a free society. Since we are genetically so diverse and our brains are so different, we're going to have different aspirations.
