EDWIN B. WILSON, MORE THAN A CATALYTIC INFLUENCE FOR PAUL SAMUELSON’SFOUNDATIONS OF ECONOMIC ANALYSIS

This paper is an exploration of the genesis of Paul Samuelson’sFoundations of Economic Analysis(1947) from the perspective of his commitment to Edwin B. Wilson’s mathematics. The paper sheds new light on Samuelson’sFoundationsat two levels. First, Wilson’s foundational ideas, embodied in maxims that abound in Samuelson’s book, such as “Mathematics is a Language” or “operationally meaningful theorems,” unified the chapters ofFoundationsand gave a sense of unity to Samuelson’s economics. Second, Wilson influenced certain theoretical concerns of Samuelson’s economics. Particularly, Samuelson adopted Wilson’s definition of a stable equilibrium position of a system in terms of discrete inequalities. Following Wilson, Samuelson developed correspondences between the continuous and the discrete in order to translate the mathematics of the continuous of neoclassical economics into formulas of discrete magnitudes. InFoundations, the local and the discrete provided the best way ofoperationalizingmarginal and differential calculus. The discrete resonated intuitively with data; the continuous did not.
