‘The culture-heroes of our liberal bourgeois civilization are anti-liberal and anti-bourgeois; they are writers who are repetitive, obsessive, and impolite, who impress by force—not simply by their tone of personal authority and by their intellectual ardor, but by the sense of acute personal and intellectual extremity. The bigots, the hysterics, the destroyers of the self—these are the writers who bear witness to the fearful polite time in which we live. It is mostly a matter of tone: it is hardly possible to give credence to ideas uttered in the impersonal tones of sanity. There are certain eras which are too complex, too deafened by contradictory historical and intellectual experiences, to hear the voice of sanity. Sanity becomes compromise, evasion, a lie. Ours is an age which consciously pursues health, and yet only believes in the reality of sickness. The truths we respect are those born of affliction. We measure truth in terms of the cost to the writer in suffering—rather than by the standard of an objective truth to which a writer’s words correspond. Each of our truths must have a martyr’. From Susan Sontag’s wonderful review of Simone Weil’s Selected Essays 1934–43.
