Abstract
This paper sheds new light on Samuelson’s early methodology as presented in his Foundations of Economic Analysis (1947) by reflecting on the similarity between his mathematical economics and Edwin B. Wilson’s mathematics. Wilson was Samuelson’s professor of advanced mathematical and statistical economics; he was also a protégé of Josiah Willard Gibbs. Wilson defined mathematics as a language that consisted of three interconnected aspects: postulational, axiomatic, and operational. In his Foundations, in a Wilsonian style, Samuelson wrote in the opening page, ‘Mathematics is a Language’ and claimed that he offered operationally meaningful theorems. In this paper, it is argued that these maxims embodied Wilson’s approach, which framed Samuelson’s mathematical and statistical thinking around 1940 and which led him to present his work as being mathematically, theoretically, and empirically well founded. Wilson’s and Percy Bridgman’s operational methodologies are also compared and Wilson is presented as a mediator between Bridgman and Samuelson.

8. Wilson pleaded for an intermediate kind of mathematics, namely not only concerned with pure mathematical consistency and acting as intermediary between mathematics and subject matters. This intermediate mathematics was more accessible for students, he thought. For Wilson’s pleas, see (Wilson, Citation1903b, Citation1911b, Citation1913, Citation1915); for the kind of mathematics that he regarded as intermediate, see (Wilson, Citation1911a).

26. Wilson’s and Bridgman’s ideas about science were emblematic expressions of American pragmatism, a philosophy of practice. These pragmatists regarded science as a human practice and sought to establish a balance between American individualism and the promotion of genuinely American scientific communities. See (Hookway, Citation2013; Menand, Citation2002; Misak, Citation2016; Mullin, Citation2007).

28. Samuelson was probably reflecting on Wilson’s skepticism of classical statistics and econometrics. Wilson was particularly critical of Karl Pearson and Ronald Fisher’s mathematical statistics as well of Ragnar Frisch’s econometrics.
