Without freedom, there is no creation, and without creation, there is no true life.
关爱别人的人,别人也必定会关爱他；给别人利益的人,别人也必定会给他利益；憎恶别人的人,别人也必定憎恶他；残害别人的人,别人也必定残害他。
世界上发生的任何事情，其意义无非是某些极大或极小值。
Fear is the main source of superstition， and one of the main sources of cruelty. To conquer fear is the beginning of wisdom， in the pursuit of truth as in the endeavour after a worthy manner of life.
