In Defence of Post Keynesian Economics: A Response to Mongiovi

‘In economics you cannot convict your opponent of error — you can only convince him of it. And, even if you are right, you cannot convince him … if his head is already so filled with contrary notions that he cannot catch the clues to your thought which you trying to throw to him’. These words were written by Keynes in an early draft of his General Theory. They correctly describe the position of Post Keynesians in responding to the criticisms that Mongiovi has developed from his unquestioning faith in classical theory. Mongiovi’s head is already so filled with Sraffian-neoRicardian classical notions that he has failed to grasp any of clues embedded in the explicit writings of Keynes in The General Theory or in other Post Keynesian writings including those listed in Mongiovi’s references.
