The General Theory of Employment, Interest and Money

"I believe myself to be writing a book on economic theory which will largely revolutionize-not I suppose, at once but in the course of the next ten years-the way the world thinks about its economic problems. I can't expect you, or anyone else, to believe this at the present stage. But for myself I don't merely hope what I say,--in my own mind, I'm quite sure." -- John Maynard Keynes
