  Perfectionism as a moral theory directs human beings to protect and promote objectively good human lives. As such, it can take an egoistic or non-egoistic form. Egoistic forms of perfectionism are well represented in the history of moral philosophy. These theories direct each human being to perfect himself as much as possible, or at least to some threshold level. Egoistic forms of perfectionism need not be narrowly self-interested. A number of perfectionist writers have held that the good of others contributes substantially to one’s own good (Green 1986; Hobhouse 1911). By promoting the good of others, one can thereby promote one’s own good.  On such views, there is no deep conflict between one’s own perfection and the perfection of others. Non-egoistic forms of perfectionism, by contrast, allow for such conflicts. They hold that each human being has a non-derivative duty to perfect others as well as a duty to perfect himself. Such views, at least in principle, can direct human beings to sacrifice their own perfection for the sake of others.[3]
