Dennis Badeen, Ph.D candidate in Social and Political Thought York University Toronto Canada. Is There a Marxist Ethics? Most contemporary (neo)-liberal economic and political theories assert that capitalism is the only viable system for which there is no alternative. To the extent that justification of this statement is offered either implicit but usually explicit arguments stemming from a conception of human nature, i.e., humans are self-interested, greedy, lazy, etc. are made to support it. These conceptions found both political and economic theory and practice while any moral or normative implication is disavowed. It would seem that a new conception of "human nature" ought to be articulated to combat these claims. Althusser's claim that Marxism is anti-humanism does not seem to help us as Althusser's critique of humanism undercuts recourse to any alternative ethical system or conception of "human nature" thus reproducing the fact/value dichotomy of bourgeois economics. I will argue that Althusser's notion of "theoretical practice" allows for a certain undogmatic form of humanism and ethics which offers an alternative to bourgeois forms without having to anchor this ethic to a notion of "human nature."
