For every individual who really is exceptional there are about fifty thousand who just imagine they are - until it's too late, and they find out they aren't after all.

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.

A Jew describes another Jew simply as a human being; a Gentile describes him, first and foremost, as a Jew.

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.

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

for every person who's stepped out of line and lived to regret it, there are two people who stayed in line because they got their values mixed and lost their nerve, and who have lived to regret it still more. You don't hear about those people because they're still in line where they don't show.
