"To understand the crisis we need to get beyond the blame game. For at the root of the crisis was not failures of character or competence, but a failure of ideas."

“Keynes's economic philosophy is thus made up of three interdependent parts: his technical macroeconomics, his embattled political philosophy and his ultimate ethical purpose.”

“Keynes displayed an awesome array of talents, without being preeminent in any. He was not a genius in the sense of being a Divine Fool as was Mozart or Wittgenstein ― extraordinary at one thing, babyish in everything else. He was a wonderful all-rounder, with a superbly efficient thinking machine. At Eton he had excelled at mathematics and classics, and throughout his life he effortlessly bridged the two cultures. He was not a remarkable mathematician. Nor was he a great philosopher. As a historian he was an inspired amateur. He had a theory of politics, but it never saved him from the charge of being politically naive. Keynes was great in the combination of his gifts. His achievement was to align economics with changes taking place in ethics, in culture, in politics and in society ― in a word, with the twentieth-century spirit. But, like Jevons, his qualities never quite jelled. That, rather than too great a haste, is why he failed to produce a work of art, although his writings are full of artistry. His best stylistic achievements were in his shorter pieces ― notably his biographical essays. In his big books he was the pamphleteer trying to rein in his imagination, school himself to the demands of a formal treatise. He had powerful intuitions of logical and historical relationships, but was not at his happiest in sustained argument. Like Marshall, his concentration came in short bursts. His temperament was too restless, his mind too constantly active, and bursting out with ideas and plans, for thinking in solitude.”

“Through Marshall's life and work the Victorian demand for authoritative social doctrine found one of its most important expressions in the Cambridge School of Economics. Maynard Keynes's relationship to that tradition is one of the central themes of this biography. That relationship was never unproblematic, because Marshall's achievement was incomplete. He had shown how the existing moral code could be made to serve society rather than God. But there was nothing in his work to show how it could be altered so as to make it possible for individuals to lead happier or more civilised lives. Marshall himself seems not to have felt any pressure to do so. But Sidgwick had, as had many other thinking Victorians. It was the reorganisation of personal life rather than the reorganisation of society which seemed the urgent problem for the next generation, especially once the soc ail and economic clouds of the 1880s and 1890s had given way to the bright sunlight of the Edwardian age.”

“The question remains: to what extent were the successes and failures of the golden age the result of Keynesian theory, however bastardized? The quick answer is: to a much greater extent in the former than in the latter. Keynesianism provided an analytical framework for organizing policy choices. It also provided ad hoc rationalizations for what governments wanted to do for other reasons. At the rhetorical level, these were important. They created the expectation that full employment would be maintained by policy. This reinforced the favourable background for business investment. To a more limited extent, Keynesian policy as practised in the 1 9 6os brought the golden age into crisis: but there were more profound reasons relating to the drift of social policy , the role of the United States in the world, and the weakness of the Bretton Woods system of international institutions. So the old coach did make a difference.”

“Maynard Keynes was born into a certain civilisation at a particular moment of history, and was one of its foremost products. He inherited both its aspirations and its tensions. He grew up in the shadow of its great figures, notably Henry Sidgwick and Alfred Marshall, the teachers and colleagues of is father. His style of thought and way of life both bear Cambridge's unmistakable imprint.”

“Keynes had a political objective. Unless governments took steps to stabilize market economies at full employment, much of the undoubted benefit of markets would be lost and political space would be opened up for extremists who would offer to solve the economic problem by abolishing markets, peace and liberty. This in a nutshell was the Keynesian 'political economy'. Keynes offers an immensely fruitful way of making sense of the slump now in progress, for suggesting policies to get us out of the slump, for ensuring, as far as is humanly possible, that we don't continue to fall into pits like the present one, and for understanding the human condition. These are the things which make Keynes fresh today.”
