The whole subject of happiness has, in my opinion, been treated too solemnly. It had been thought that man cannot be happy without a theory of life or a religion. Perhaps those who have been rendered unhappy by a bad theory may need a better theory to help them to recovery, just as you may need a tonic when you have been ill. But when things are normal a man should be healthy without a tonic and happy without a theory. It is the simple things that really matter. Man is an animal, and his happiness depends on his physiology more than he likes to think. This is a humble conclusion, but I cannot make myself disbelieve it. Unhappy businessmen, I am convinced, would increase their happiness more by walking six miles every day than by any conceivable change of philosophy.
在我看来，人们一直都太过于严肃地对待关于快乐的话题。过去一直有这样的看法：如果没有一种生活的理论或者宗教信仰，人是不可能幸福的。也许那些由于生活理论不佳而导致不快乐的人需要一种更好的理论帮助他们重新快活起来，就像你生病需要吃补药一样。但是，正常情况下，一个人不吃补药也应当是健康的；没有生活的理论也应当是幸福的。真正有关系的是一些简单的事情。 人是动物，他的幸福更多的时候取决于其生理状况而非思想状况。这是一个很庸俗的理论，然而我无法使自己怀疑它。我确信，不幸福的商人与其寻找可能的理论来使自己幸福，还不如每天步行六英里更见效。
