"It was one of the self-delusions of the age that the Sixties were an era of heightened political consciousness. ‘Everyone’ (or at least everyone under twenty-five attending an educational establishment and drawn to radical ideas) was in the streets and mobilized for a cause. The deflation of the causes—and the demobilization of the coming decades—thus confers in retrospect an air of failure upon a decade of frenetic political activity. But in certain important respects the Sixties were actually a vital decade for the opposite reason: they were the moment when Europeans in both halves of the continent began their definitive turn away from ideological politics. Thus the slogans and projects of the Sixties’ generation, far from re-awakening a revolutionary tradition whose language and symbols they so energetically sought to reinvigorate, can be seen in hindsight to have served as its swansong. In Eastern Europe, the ‘revisionist’ interlude and its tragic dénouement saw off the last illusions of Marxism as a practice. In the West, Marxist and para-Marxist theories soared clear of any relationship to local reality, disqualifying themselves from any future role in serious public debate. In 1945 the radical Right had discredited itself as a legitimate vehicle for political expression. By 1970, the radical Left was set fair to emulate it. A 180-year cycle of ideological politics in Europe was drawing to a close."
