The mind is divided into parts that sometimes conflict. Like a rider on the back of an elephant, the conscious, reasoning part of the mind has only limited control over the automatic, emotional part.
心灵分为有时会相互冲突的部分。就像骑在大象背上的骑手，意识、推理的心灵部分对自动、情感的部分只有有限的控制。
All the effects of nature are only the mathematical consequences of a small number of immutable laws.
把所有的鸡蛋放在一个篮子里是可以的，只要你能控制那个篮子。
