It's not facts that hurt people, it's their attitude towards facts.

There is nothing in the world so dangerous, or so overwhelming as stupidity; perhaps there is no more of it now than there has been at any time, but I do not think the witless of past generations had so much power. The powers of darkness are the powers of misdirected knowledge.

I don't want to get married ... I'm certainly not going to give up the work I've wanted to do all my life for the sake of it, any more than I'd expect my husband, if he were a doctor or a lawyer, for example, to give up practising medicine or law in order to marry me.

If you choose to turn your back, you don't really have a say in what goes on behind it.

There is nothing in the education of the average non-scientific human being to discourage him from the habit of generalizing from little or no evidence, and worse still and far more important, nothing to discourage him from the habit of starting with a generalization and ending up with the individual, instead of the other way round.

there are people who are born superficial ... They prefer not to have to deal with more than a limited number of oversimplified ideas - they prefer the book reviews to the books, the headlines and the leading paragraph to the full report, the generalization to the facts, and the negative to the positive.

One doesn't expect justice from life ... it's the function of human beings to put it there.
