Is there such a thing as human nature? In Marxism and Human Nature, Sean Sayers defends the controversial theory that human nature is a historical phenomenon. Those who disagree with this theory counter that it leads to forms of scepticism and relativism which are at odds with morality; Sayers argues that this need not be the case. Drawing on the work of Marx and Hegel, he develops a historical account of human needs and powers which provides the basis for a distinctive form of Marxist humanism.
