This means that every action that helps others turns into a selfish one because the action gives satisfaction or happiness to the human that performs the action.

Secondly, we seek our own happiness; therefore our desires seek happiness not selfishness. Next, I will give arguments against psychological egoism. First, the argument is flawed in onto itself.
