FAKKIR.XYZ | JURNAL – Economic man, the man who acts on pure economic motives alone, is the concept of man at the heart of mainstream economics.1 Heterodox economists, while acknowledging that economic man has served usefully for some purposes, know in different ways that economic man is, because it leaves out too much of human nature, a deficient concept of man. They are uncomfortable at best with the idea of characterizing humans in such a reductionist way. This paper proposes to use the comprehensive view of human nature developed by Ken Wilber to point to the specific deficiencies of economic man. With Wilber’s model of human development as the backdrop, it is possible to map the different schools of thought with respect to each other, showing how each of their overlapping conceptions of man include some important elements missing in economic man but fail to include other elements. Finally, the broad conception of human nature allows us to be quite suggestive concerning how economics as a whole, and notably heterodox economics, can improve by using a broader concept of man.
