Keynes y el marxismo

De una carta de Keynes a George Bernard Shaw:

My feelings about Das Kapital are the same as my feelings about the Koran. I know that it is historically important and I know that many people, not all of whom are idiots, find it a sort of Rock of Ages and containing inspiration. Yet when I look into it, it is to me inexplicable that it can have this effect. Its dreary, out-of-date, academic controversialising seems so extraordinarily unsuitable as material for the purpose. But then, as I have said, I feel just the same about the Koran. How could either of these books carry fire and sword round half the world? It beats me. Clearly there is some defect in my understanding … whatever the sociological value of [Marx’s Das Kapital], I am sure that its contemporary economic value (apart from occasional but inconstructive and discontinuous flashes of insight) is nil.
