Literally, I was reading one of the philosophy of ethics professors from Harvard talk about ethics in general and when they got into Marxism and Marxists (as a representative of a form of consequentialist ethics, which it isn't really) and they literally stated something that was specifically the opposite of dialectical materialist ethical theory, of which the majority comes from the Anti-Durhing by Engels, as the Marxist's view of ethics, without actually citing any individual Marxist, or even Marx himself, while all other views had specific nuanced views defined by individual thinkers of the theory. And this person is supposed to be a leading scholar of virtue ethics. Ayn Rand was literally taken more seriously as an academic source
