Abstract
In this paper I propose to answer the age-old reductio against vegetarianism, which is usually presented in the form of a sarcastic question. Addressing the question takes on special significance in the light of arguments which seem to show that even nonsentient life is intrinsically valuable. Thus, I suggest that we rephrase the question in the following manner: When beings evolve into societies of moral agents are they entitled merely to assume that they retain their license to destroy other life in order to sustain their own? I answer in the negative. I argue that such societies must continually earn that right by engaging in activity that makes up for and augments the values that they destroy. Unlike other biological beings, humans have complete control over what they eat, whether they eat, and whether they reproduce. Hence, the appeals to necessity that are ubiquitous in justifications of both vegetarian and non-vegetarian diets are inauthentic and must be accordingly forsaken. We will have to appeal instead to the value of particular human activities that are fueled by our consumption of other lives.
