“Keynes was a great economist. In every discipline, progress comes from people who make hypotheses, most of which turn out to be wrong, but all of which ultimately point to the right answer. Now Keynes, in The General Theory of Employment, Interest and Money,set forth a hypothesis which was a beautiful one, and it really altered the shape of economics. But it turned out that it was a wrong hypothesis. That doesn't mean that he wasn't a great man!”

“We all want progress, but if you're on the wrong road, progress means doing an about-turn and walking back to the right road; in that case the man who turns back soonest is the most progressive.”

“Progress means getting nearer to the place you want to be. And if you have taken a wrong turn, then to go forward does not get you any nearer.If you are on the wrong road, progress means doing an about-turn and walking back to the right road; and in that case the man who turns back soonest is the most progressive man.”

“There are many hypotheses in science which are wrong. That’s perfectly all right: it’s the aperture to finding out what’s right. Science is a self-correcting process.”

“Patriotism is a word; and one that generally comes to mean either my country, right or wrong, which is infamous, or my country is always right, which is imbecile.”

“...indeed it is in the General Cemetery that the results of progress are set out before the eyes of the studious or the merely curious, there are even those who say that a cemetery like this is a kind of library which contains not books but buried people, it really doesn't matter, you can learn as much from people as from books.”
