People all have moral sensibility. Though it is hard to pursue justice and distinguish right from wrong, once the ideal is achieved, the happiness felt will definitely be broader, deeper, and more exciting than the state of satisfaction described in A Great Revolution.
人都有道德情感，追求正義或辨明大是大非的過程儘管艱辛，但一旦理想落實，所獲得的快感，絕對比《腦內革命》所描述的滿足狀態更為高亢，更為廣遠。
