egoism

The impossibility of disproving egoism may sound like a virtue of the theory, but, as philosophers of science know, it’s really a fatal drawback..无法否定利己主义可能听上去像是这种理论的优点，但正如科学哲学家所知，这其实是一个致命的缺点。

So the psychological lure of egoism as a theory of human action is partly explained by a certain humility or skepticism people have about their own or others’ motives..因此，利己主义作为一种人类行为理论，其产生心理诱惑的部分原因是人们对已自身或他人动机具有的某种谦逊或怀疑态度。
