* The Englishman William Stanley Jevons (1835–82) and the Austrian Carl Menger (1840–1921) are of course still honoured today in academic economics as co-founders of the ‘marginalist’ school. Shaw, as a leading member of the Fabian Society, was very much a part of the embryonic socialist movement in London in Engels’s last years. Engels’s verdict on Shaw: ‘very talented and witty as a belletrist but absolutely useless as an economist and politician, although honest and not a careerist’ (Engels to Kautsky, 4 September 1892; Selected Correspondence, London, 1965, p. 446).
