Psychological egoismPsychological egoism
is the view that we are always motivated by self-interest, even in seeming acts of altruism
Psychological egoism should be contrasted well with ethical egoism, which is the view that we always ought to be motivated by self-interest.
Max Stirner is known for holding this view of the human psyche. (He was also a proponent of ethical egoism.)
Because psychological hedonism makes a very strong claim (we are always motivated by self-interest), it appears to be quite easy to refute empirically.
