Understanding Keynes: A Response to Spahn's Review of 'John Maynard Keynes'

First paragraph: »In Economics you can not 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 are trying to throw to him« (attributed to Keynes by Austin Robinson in his inaugural Keynes lecture to the British Academy on 22 April 1971) Peter Spahn’s review of my latest book, entitled John Maynard Keynes (2007), is an excellent illustration of a case where the reviewer’s head is already filled with so many »contrary notions « that he can not catch the clues to Keynes’s analytical framework that I am presenting to the reader of my book. Spahn recognizes that the book »is worth reading«, but he complains that the book has »many repetitions«.
