I believe that the same source that inspired Copernicus to state that the planets move around the sun is the same source that inspired him to state the quantity theory. And since the first theory is correct, and no more in doubt, so will all come to the realization that his quantity theory is correct, including Keynesian economics. It's a matter of time.
