One of the favorite maxims of my father was the distinction between the two sorts of truths, profound truths recognized by the fact that the opposite is also a profound truth, in contrast to trivialities where opposites are obviously absurd.
我父亲最喜欢的格言之一是区分这两种真理，深刻的真理是由这样一个事实认识到的，即对立也是深刻的真理，与之形成鲜明对比的是，对立显然是荒谬的琐事。
