This paper focuses on Mary Midgley's influential discussions, over more than thirty years, of the relationship between human beings and animals, in particular on her concern to ‘remove the barriers’ that stand in the way of proper understanding and treatment of animals. These barriers, she demonstrates, have been erected by animal science, epistemology and mainstream moral philosophy alike. In each case, she argues, our attitudes to animals are warped by approaches that are at once excessively abstract, over-theoretical and guilty of (...) a collective hubris on the part of humankind. In keeping with Midgley's own position, it is argued in this paper that, to remove these barriers, what is required is not yet another theory of how and why animals matter, but attention to actual engagements with animals and to the moral failings or vices that distort people's relationships with them.
