"Abélard would find most of his old problems sensitive to his touch today. Time has settled few or none of the essential points of dispute. Science hesitates, more visibly than the Church ever did, to decide once for all whether Unity or Diversity is ultimate law; whether order or chaos is the governing rule of the Universe, if Universe there is; whether anything except phenomena exists. Even in matters more vital to society, one dares not speak too loud. Why, and for what, and to whom, is man a responsible agent? Every jury and judge, every lawyer and doctor, every legislator and clergyman has his own views, and the law constantly varies. Every nation may have a different system. One court may hang, and another may acquit for the same crime, on the same day; and Science only repeats what the Church said to Abélard, that where we know so little, we had better hold our tongues."
