Robinson discusses the “Keynesian revolution,” arguing that 1. Keynes brought back something of the hard-headedness of the Classics, 2. Keynes brought back the moral problem that laisser-faire theory had abolished and 3. Keynes brought back time into economic theory. The author takes a detailed look at Keynes’ work in economics, concluding that the Keynesian revolution has left us “in the uncomfortable situation of having to think for ourselves.”
