 Altruism is not necessarily admirable. It is to be admired only in circumstances in which it is appropriate to act for another’s sake—and only when what one aims to do for another really does benefit that individual. If one seeks what one takes to be the good of others for their sake, but is mistaken about what is really good for them, one’s action is defective. Altruism is fully admirable only when combined with a correct understanding of well-being.
