We have almost reached the point where praise of rationality is held to mark a man as an old fogey regrettably surviving from a bygone age.

Formality Thus the absence of all mention of particular things or properties in logic or pure mathematics is a necessary result of the fact that this study is, as we say, "purely formal".

Bertrand Russell
We all have a tendency to think that the world must conform to our prejudices. The opposite view involves some effort of thought, and most people would die sooner than think in fact they do so.
Bertrand Russell

There are infinite possibilities of error, and more cranks take up fashionable untruths than unfashionable truths.

Bertrand Russell
Men fear thought as they fear nothing else on earth - more than ruin, more even than death.
Bertrand Russell

If the ordinary wage-earner worked four hours a day, there would be enough for everybody and no unemployment -- assuming a certain very moderate amount of sensible organization. This idea shocks the well-to-do, because they are convinced that the poor would not know how to use so much leisure. In America men often work long hours even when they are well off; such men, naturally, are indignant at the idea of leisure for wage-earners, except as the grim punishment of unemployment; in fact, they dislike leisure even for their sons.

A man of Seville is shaved by the Barber of Seville if and only if the man does not shave himself. Does the barber shave himself?

If you had the power to destroy the world, would you do so?

Bertrand Russell
When I say that children should be told about sex, I do not mean that they should be told only the bare physiological facts; they should be told whatever they wish to know. There should be no attempt to represent adults as more virtuous than they are, or sex as occurring only in marriage. There is no excuse for deceiving children. And when, as must happen in conventional families, they find that their parents have lied, they lose confidence in them, and feel justified in lying to them.
Bertrand Russell

The average man's opinions are much less foolish than they would be if he thought for himself.

Bertrand Russell
The world that I should wish to see would be one freed from the virulence of group hostilities and capable of realizing that happiness for all is to be derived rather from co-operation than from strife. I should wish to see a world in which education aimed at mental freedom rather than imprisoning the minds of the young in rigid armor of dogma calculated to protect them through life against the shafts of impartial evidence.
