Quotes

• “The General Theory caught most economists under the age of 35 with the unexpected virulence of a disease first attacking and decimating an isolated tribe of south sea islanders. Economists beyond 50 turned out to be quite immune to the ailment. With time, most economists in between began to run the fever, often without knowing or admitting their condition.”
• “Science is not art. Yet, despite the lack of complete identity between art and science, there is much in common among different creative processes.”
• “Just as Hegel is said to have understood his philosophy for the first time when he read its French translation, Vilfredo Pareto could have learned what it was he meant exactly to say when he read Bergson's 1938 classic.”
• “I was lucky to enter economics in 1932. Analytical economics was poised for its take-off. I faced a lovely vacuum that young economists today can hardly imagine. So much remained to be done. Everything was still in an imperfect state. It was like fishing in a virgin lake: a whopper at every cast, but so many lovely new specimens that the palate never cloyed.”
• “The existence of analogies between central features of various theories implies the existence of a general theory which underlies the particular theories and unifies them with respect to those central features. This fundamental principle of generalization by abstraction was enunicated by the eminent American mathematician E. H. Moore more than thirty years ago. It is the purpose of the pages that follow to work out its implication for theoretical and applied economics.”
• “The general method involved may be very simply stated. In cases where the equilibrium values of our variables can be regarded as the solutions of an extremum (maximum or minimum) problem, it is often possible regardless of the number of variables involved to determine unambiguously the qualitative behavior of our solution values in respect to changes of parameters.”
