Keynesian macroeconomics is, at heart, a rationalization for collectivized state planning . Its progenitor was the 18th century quest to discover social science laws of behavior paralleling Newton's mathematics and laws of motion that explained movements of the planets and of the earth around the sun. By the early 1800s French socialist intellectuals were confident that they had identified sociological laws that would enable them to create a secular paradise here on earth. A hundred years later, economist John Maynard Keynes propounded his ideas in the same tradition.
