Xenophobia looks like becoming the mass ideology of the 20th-century fin-de-siecle. - Eric Hobsbawm

Marx's ideas became the doctrines inspiring the labour and socialist movements of most of Europe. Mainly via Lenin and the Russian Revolution they became the quintessential international doctrine of twentieth-century social revolution, equally welcomes as such from China to Peru. Through the triumph of parties identified with these doctrines, versions of these ideas became the official ideology of the states in which, at their peak, something like a third of the human race lived, not to mention political movements of varying size an importance in the rest of the world. The only individually identifiable thinkers who have achieved comparable status are the founders of the great religions in the past, and with the possible exception of Muhammad none have triumphed on a comparable scale with such rapidity. No secular thinker can be named beside him in this respect.

The greatest cruelties of our century have been the impersonal cruelties of remote decision, of system and routine, especially when they could be justified as regrettable operational necessity.

Except perhaps for such irreducible sexual groups as parents and their children, the ‘man’ of classical liberalism (whose literary symbol was Robinson Crusoe) was a social animal only insofar as he co-existed in large numbers. Social aims were therefore the arithmetical sum of individual aims. Happiness (a term which caused its definers almost as much trouble as its pursuers) was each individual’s supreme object; the greatest happiness of the greatest number, was plainly the aim of society.
