Few people think more than two or three times a year; I have made an international reputation for myself by thinking once or twice a week.

It is the inefficiency and sham of ... our schools ... that save us from being dashed on the rocks of false doctrine instead of drifting down the midstream of mere ignorance.

When you want to put something into your part that is not in the play, you must ask the author-or some other author-to lead up to the interpolation for you. Never forget that the effect of a line may depend not on its delivery, but on something said earlier in the play, either by somebody else or by yourself, and that if you change it, it may be necessary to change the whole first act as well.

I must remind you that our credulity is not to be measured by the truth of the things we believe. When men believed that the earthwas flat, they were not credulous: they were using their common sense, and, if asked to prove that the earth was flat, would have said simply, "Look at it." Those who refuse to believe that it is round are exercising a wholesome skepticism.

It is the highest creatures who take the longest to mature, and are the most helpless during their immaturity.

A part of eugenic politics would finally land us in an extensive use of the lethal chamber. A great many people would have to be put out of existence simply because it wastes other people's time to look after them.

The road to ignorance is paved with good editors.
