I have been gradually coming under the conviction, disturbing for a professional theorist, that there is no such thing as economics - there is only social science applied to economic problems.

Humble, honest, ignorance is one of the finest flowers of the human spirit

The tourist business is a trap, it is a tained honey; Man clearly should have stayed in bed, and not invented money.

The economy of the future might be called the "spaceman economy," in which the earth has become a single spaceship, without unlimited reservoirs of anything.

Without the heroic, man has no meaning; without the economic, he has no sense. Economic man is most likely to be economic woman - a good wife, pulling the coat tails of her heroic husband, checking his extravagances of speech and action with words of caution and good sense. But without the heroic coat tails to pull, life for both of them would be dull and savorless indeed.

The ability to work with systems of general equilibrium is perhaps one of the most important skills of the economist - a skill which he shares with many other scientists, but in which he has perhaps a certain comparative advantage.

The organization of science into disciplines sets up a series of ghettos with remarkable distances of artificial social space between them.
