“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.”
