Biologism -- the belief that human beings are essentially animals and can be understood in biological terms -- is gaining increasing acceptance in contemporary thought. This trend is seemingly legitimised by genuine, often spectacular, advances in biological science: in human genetics, evolutionary theory and neuroscience. Our propensities, we are told, can be accounted for by "a gene for" this or that; everyday behaviour can be explained in Darwinian terms; and human consciousness is identified with the activity of the evolved brain.Ultimately, so the story goes, all that we do, think and feel is subordinated to the imperative of ensuring that we behave in such a way as to, individually or collectively, maximise the chances of replicating our genetic material. In Aping Mankind, Raymond Tallis argues that the rise of this way of thinking is a matter of profound concern. He demonstrates that by denying human uniqueness, and minimising the differences between humans and their nearest animal kin, biologism misrepresents what we are, offering a grotesquely simplified and even degrading account of humanity, which has dire consequences: by seeing ourselves as animals we may find reasons for treating each other like them.In a devastating critique Tallis exposes the exaggerated claims made for the ability of neuroscience and evolutionary theory to explain human consciousness, behaviour, culture and society and shows that human beings are infinitely more interesting and complex than they appear in the mirror of biologism.
