Edward Said. Here, Malik argues that such theories misinterpret the relationship between the West and other cultures, and are detrimental to the possibility of social equality. In its essence, Malik argues, postmodernism is defeatist – it is prepared to accept a place for marginalised groups within society without demanding true equality. Man, Beast and Zombie Man, Beast and Zombie investigates the historical roots, philosophical assumptions and alleged methodological problems of contemporary theories of human nature, in particular evolutionary psychology and cognitive science. He argues that, "The triumph of mechanistic explanations of human nature is as much the consequence of our culture's loss of nerve as it is of scientific advance." (pages 13–14) While rejecting epistemic relativism, with its denial of an objective truth about the world, Malik insists that scientific theories of human nature are, in practice, shaped by cultural influences, as well as being responsive to data. He argues that the scientific study of human nature has been distorted by post-war cultural pessimism. In examining evolutionary psychology and related theories, Malik distinguishes between these theories, which he sees as a form of universal Darwinism (attributing explanatory power to Darwinian theory in a wide range of domains), and the work of "circumspect Darwinists" (who are cautious about its explanatory power) (197). Though Malik sees human beings as a product of evolution, and that universal Darwinist theories have merit when applied to non-human animals – and perhaps some merit when applied to human behaviour – he is sceptical about how far they can be applied to human beings. In particular, theories of a biologically-evolved human nature cannot, alone, account for the transformations of behaviour that arose from our immersion in a symbolic world built up out of language and culturally-meaningful relationships. Thus, "the scientific tools with which we investigate animal behaviour are inadequate for understanding human behaviour" (p. 231). In discussing cognitive science and philosophy of mind, Malik concludes that each human being possesses "an extended mind"; a brain becomes a human mind only by its immersion in social relationships together with "other brains linked by language and culture." (p. 331) Human meaning derives not from nature but from the language-linked social network of which we are part." (p. 334) If we did succeed in creating a machine capable of participating in a human society like a human being, it would be human (334–35). In the final chapter of Man, Beast
