Economists can be called the worldly philosophers for they sought to embrace in a scheme of philosophy the most worldly of man's activities-his drive for wealth.

Mathematics has given economics rigor, but alas, also mortis.

Capitalism is the only society in human history in which neither tradition nor conscious direction supervises the total effort of the community; it is the only society in which the future, the needs for tomorrow, are entirely left to an automatic system.

The use of mathematics has brought rigor to economics. Unfortunately, it has also brought mortis.

If one could divine the nature of the economic forces in the world, one could foretell the future.

As the histories of ancient and modern democracies illustrate, the pressure of political movement in times of war, civil commotion, or general anxiety pushes in the direction of authority, not away from it.

Less than seventy-five years after it officially began, the contest between capitalism and socialism is over: capitalism has won.
