Ethical Egoism
built 655 days ago
The term ethical egoism has been applied retroactively to philosophers such as Bernard de Mandeville and to many other materialists of his generation, although none of them declared themselves to be egoists. Note that materialism does not necessarily imply egoism, as indicated by Karl Marx, and the many other materialists who espoused forms of collectivist altruism.
