Egoism
Some ideas of egoism can be studied in moral psychology. For example, Friedrich Nietzsche says that many people wrongly think that being "good" is related to not being egoistic. He says that this idea only appeared because priestly values took over from noble values . Nietzsche says that the idea that actions are egoistic or altruistic is pseudo-psychology. He says the truth is that "there are no such things as egoistic and altruistic actions". Morality tries to damage psychology with these false ideas, he says. He also says that this kind of morality always serves the needs and wants of some people over others. A British researcher named Alexander Moseley instead says that egoists don't believe psychology can understand people's motivations.
