Introduction

In his magisterial History of Economic Analysis (1954), Joseph Schumpeter, argues that in economics any “. . . analytic effort is of necessity preceded by a preanalytic cognitive act that supplies the raw material for the analytic effort. In this book, this preanalytic cognitive act will be called Vision” (p. 41). Schumpeter goes on to illustrate his point by discussing the close linkages between Keynes’s macroeconomics in his Economic Consequences of the Peace (1920) and the General Theory (1936).
