We Have No Moral Duty to Eat Meat: A Reply to Nick Zangwill

Nick Zangwill has argued that we have a moral duty to eat meat. His argument applies to the flesh of those domesticated animals who (a) would not have existed had it not been for the practice of killing and eating them; and (b) have lives that contain more good than bad—and thus, on his view, have “lives worth living.” In my reply, I point to various features of his argument that are unclear. I seek to render explicit the various premises and inferences of his argument. I argue that there are problems with at least some of the premises. I also argue that his argument as a whole is liable to a reductio ad absurdum, which he considers, but to which he responds inadequately. I conclude that we ought to reject his argument.
