Eating Meat and Eating People by Cora Diamond

"This  paper is a response to a certain sort of argument defending the rights of animals. Part I is a brief explanation of the background and of the sort of argument  I  want  to  reject;  Part  II  is  an  attempt  to  characterize those arguments:  they  contain  fundamental  confusions  about  moral  relationsbetween people  and people and between people  and animals. And Part III is  an  indication  of  what  I  think  can  still  be  said  on-as it  were-the animals' side. "
