“Humans are always selfish,” and Rachels, “Humans are not always selfish.” We’re discussing psychological egoism. What do you think of the theory? Is psychological egoism correct and we cannot act without benefiting ourselves? Or are people capable of doing altruistic acts? For another question, should we assume that selfishness is the foundation of ethics (or justice) as Glaucon suggests? Or are we able start discussing ethics from the assumption that people are altruistic?
