One of the main objections to psychological selfishness is that it is an example of a non-falsifiable theory. It is very unlikely that you will know how selfish or altruistic your motivation is. This difficulty is related to the fact that it is difficult to know with certainty one`s deep motivation. It can work in both ways. On the one hand, psychological egoists have the opportunity to assert that even a person who emphasizes that he is doing charity for an altruistic reason could be wrong deep within. On the other hand, precisely because it is difficult to be sure of one`s own deep motivation, the assumption of psychological egoists that we are all selfish deep down seems unjustified. If so, deviating from the truth becomes an ethically recommended path. And my father, without needing his calls, turned his back on the selfish. The question of what constitutes a moral theory is controversial. An ethical egoist could question any coercion used against them. But a cleaner response is to move on to rational selfishness, to make claims about what to do and to ignore the subject, which is morally right.
This returns to what ethical egoists intend to do, while the issue of restrictions on moral theories is evaded. Finally, few ethical egoists think that selfishness gives the right content of morality, while thinking that what they have the most reasons is determined by non-selfish thinking. . . .
