Is a man what he seems to the astronomer, a tiny lump of impure carbon and water crawling impotently on a small and unimportant planet? Or is he what he appears to Hamlet? Is he perhaps both as once?

One must expect a war between U.S.A. and U.S.S.R. which will begin with the total destruction of London. I think the war will last 30 years, and leave a world without civilised people, from which everything will have to build afresh - a process taking (say) 500 years.
The desire to understand the world and the desire to reform it are the two great engines of progress, without which human society would stand still or retrogress.
The fundamental defect of Christian ethics consists in the fact that it labels certain classes of acts 'sins' and others 'virtue' on grounds that have nothing to do with their social consequences.

Africans had to be taught that nudity is wicked; this was done very cheaply by missionaries.
I suggest to young professors that their first work should be written in a jargon only to be understood by the erudite few. With that behind them, they can ever after say what they have to say in a language 'understand of the people.'
Shakespeare . . . If he does not give you delight, you had better ignore him [if you can].
The doctrine (of) maintaining that the language of daily life, with words used in their ordinary meanings, suffices for philosophy . . . I find myself totally unable to accept . . . .

While I am as convinced a Socialist as the most ardent Marxian, I do not regard Socialism as a gospel of proletarian revenge, nor even, primarily, as a means of securing economic justice.
