The one discussion of economics that I've encountered in Kuhn's work comes 
from "The Structure of Scientific Revolutions" (2nd edition), p. 161: "It 
may, for example, be significant that economists argue less about whether 
their field is a science than do practitioners of some other fields of 
social science. Is that because economists know what science is? Or is it 
rather economics about which they agree?" 
 
Do economists argue less about whether their field is a science? If 
so, why? I'm sure others must be aware of other discussions of economics by 
Kuhn.
