A strategic ethical egoist would argue that any cooperation we see in modern society is not the result of “genuine moral behavior” (as defined as giving other 's interests weight in their own right), but instead a sort of game of self-interested cooperation whereby actors coinciding actions result in mutually beneficial results. This is presented in David Gauthier 's model of the Constrained Maximizer who , in the pursuit of maximum utility achievement, decide to cooperate with those who have a proven track record of cooperation and defect on cooperation with those who have shown to defect on previous cooperative engagements.

A metaphysical egoist would go as far as saying the existence of selfless desire towards a loved one is merely a self-interested action to an extended form of one 's self. This can be seen in Aristotle equation of friend, or loved one, to an extended self when he says “a friend is another self, and therefore, just as
