The use of quantity of money as a target has not been a success. I'm not sure that I would as of today push it as hard as I once did. - Milton Friedman

In a free society, it is hard for “good” people to do “good,” but that is a small price to pay for making it hard for “evil” people to do “evil,” especially since one man's good is anther's evil.

Sloppy writing reflects sloppy thinking.

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!
