道德生活指向幸福生活。然而道德生活除了带来幸福之外,还有其它副产品。柏拉图讲先有城邦幸福才有个人的幸福,亚里士多德会讲幸福生活是灵魂合于德性的完满实现活动。前者可能会带来极权,后者带来文明对本能的压抑,会产生一系列问题。如果道德生活能获得幸福,有两个前提是:社会是道德的;对本能的压抑减少、快乐是值得追求的。 Moral life points to a happy life. However, in addition to bringing happiness to moral life, there are other by-products. Plato said that there is happiness in the city first, and that Aristotle will say that happy life is the perfect fulfillment of the soul in harmony with virtue. The former may bring totalitarians, which bring civilization to instinctive repression, there will be a series of problems. If the moral life can be happy, there are two prerequisites: the society is moral; the reduction of instinct, happiness is worth pursuing.
