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.
