In 1968 there appeared in New Left Review an essay by its editor, Perry Anderson, which attracted considerable attention. Detecting in the student unrest then at its height ‘stirrings of a revolutionary consciousness’, Anderson was concerned to identify (and of course attack) the main elements ofthat British cultural conservatism which, in his view, the burgeoning revolutionary consciousness must overthrow. In brief, his view was that British intellectual life was dominated by a ‘“White”, counter-revolutionary emigration’ from Eastern and Central Europe – men who had fled the instability of their own societies for the continuity and order of the British tradition. Among them Anderson listed, as the dominant influence in social theory, Karl Popper. This was an accolade of sorts, but by no means any kind of intellectual tribute, for Anderson went on to dismiss Popper as nothing more than a ‘fluent ideologue’, incompetent alike in sociology and political theory.
