 In the field of economic philosophy and method, Katouzian has published a critique of economic method, maintaining that economic theory and theorizing could not be described as scientific, once the economists’ own criteria for scientificity are applied to their works.The subject further involved him in a critique of the philosophies of science developed by Karl Popper and Thomas Kuhn arguing that Popper's criteria were no longer applied by modern scientists, and that Kuhn's historical generalizations were largely circular.Katouzian has taught the history of nineteenth and twentieth century Iran at Oxford University.
