“I keep having the same experience and keep resisting it every time. I do not want to believe it although it is palpable: the great majority of people lack an intellectual conscience. Indeed, it has often seemed to me as if anyone calling for an intellectual conscience were as lonely in the most densely populated cities as if he were in a desert. Everybody looks at you with strange eyes and goes right on handling his scales, calling this good and that evil. Nobody even blushes when you intimate that their weights are underweight; nor do people feel outraged; they merely laugh at your doubts. I mean: the great majority of people does not consider it contemptible to believe this or that and to live accordingly, without first having given themselves an account of the final and most certain reasons pro and con, and without even troubling themselves about such reasons afterward: the most gifted men and the noblest women still belong to this "great majority." But what is goodheartedness, refinement, or genius to me, when the person who has these virtues tolerates slack feelings in his faith and judgments and when he does not account the desire for certainty as his inmost craving and deepest distress--as that which separates the higher human beings from the lower.”
