In ethics Keynes was a Platonist, in politics he was an Aristotelian. His ethics pointed him towards the ideal; his politics towards moderation. - Robert Skidelsky

I could never take seriously the standard view that historians should take ideas as give, and confine themselves to their effects; or even worse, the Marxist-cum-Freudian view that ideas have no independent effects, but are themselves the effects of economic or psychological causes. If one accepts that ideas shape events, then a historian has to be able to describe the ideas or doctrines relevant to his topic as accurately as can a theologian, a philosopher, or an economist. If that requires a specialised training, so be it. Any account of Keynes's influence that failed to engage with his 'theology' would be seriously incomplete as history.

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.

Like Odysseus, Keynes was a successful, not a tragic, hero. He heard the beautiful singing of the Sirens, but took precautions against being shipwrecked, keeping to the course for which his talents and the state of the world predestined him. Artfully, he strove for the best of all worlds, in his life and his work, and miraculously, came close to achieving it.
