We keep unaltered as much of our old knowledge, as many of our old prejudices and beliefs, as we can.

The most violent revolutions in an individual's beliefs leave most of his old order standing. Time and space, cause and effect, nature and history, and one's own biography remain untouched. New truth is always a go-between, a smoother-over of transitions. It marries old opinion to new fact so as ever to show a minimum of jolt, a maximum of continuity.

The art of being wise is the art of knowing what to overlook.

Knowledge of other people's beliefs and ways of thinking must be used to build bridges, not to create conflicts.
