A person who rejects egoism and promotes the wellbeing of others or society over selfish interests.
From antiegoism + -ist (person who practices or believes). The -ist suffix names someone who actively practices or advocates for the philosophy of antiegoism.
Counterintuitively, some antiegoists argued their unselfishness created the happiest societies—and psychological research now suggests they might be right: people in more cooperative societies report higher wellbeing.
