gave a talk on the same subject to economists at Oxford in February 1935. This was the final building block of the General Theory. The book was finished in December 1935 and published in February 1936. Observations on its readability Many economists found General Theory difficult to read, with Étienne Mantoux calling it obscure, Frank Knight calling it difficult to follow, Michel DeVroey commenting that "many passages of his book were almost indecipherable"., and Paul Samuelson calling the analysis "unpalatable" and incomprehensible. Raúl Rojas dissents, saying that "obscure neo-classical reinterpretations" are "completely pointless since Keynes' book is so readable". Reception Keynes did not set out a detailed policy program in The General Theory, but he went on in practice to place great emphasis on the reduction of long-term interest rates and the reform of the international monetary system as structural measures needed to encourage both investment and consumption by the private sector. Paul Samuelson said that the General Theory "caught most economists under the age of 35 with the unexpected virulence of a disease first attacking and decimating an isolated tribe of South Sea islanders." Praise Many of the innovations introduced by The General Theory continue to be central to modern macroeconomics. For instance, the idea that recessions reflect inadequate aggregate demand and that Say's Law (in Keynes's formulation, that "supply creates its own demand") does not hold in a monetary economy. President Richard Nixon famously said in 1971 (ironically, shortly before Keynesian economics fell out of fashion) that "We are all Keynesians now", a phrase often repeated by Nobel laureate Paul Krugman (but originating with anti-Keynesian economist Milton Friedman, said in a way different from Krugman's interpretation). Nevertheless, starting with Axel Leijonhufvud, this view of Keynesian economics came under increasing challenge and scrutiny and has now divided into two main camps. The majority new consensus view, found in most current text-books and taught in all universities, is New Keynesian economics, which accepts the neoclassical concept of long-run equilibrium but allows a role for aggregate demand in the short run. New Keynesian economists pride themselves on providing microeconomic foundations for the sticky prices and wages assumed by Old Keynesian economics. They do not regard The General Theory itself as helpful to further research. The minority view is represented by post-Keynesian economists, all of whom accept Keynes's fundamental critique of the neoclassical concept of long-run equilibrium, and some of whom think
