Abstract

This essay addresses Paul Thompson’s claim (made in two pieces separated by 20 years) that “you are not what you eat”; that is, that dietetics is not an ethical matter. I issue a series of challenges to Thompson’s position, all of which have a common underpinning, namely that his critiques of dietetics sound more like the sort I’d expect from an analytic philosopher than from a pragmatist. They are rooted not only in a tightly drawn (if widely philosophically accepted) definition of ethics, but also in a very tightly drawn definition of diet, a definition that doesn’t take much account of context. That the stream from producer to consumer is continuous argues for not forgetting that eating is one link in a chain of activities—a link that literally cannot exist without those that come before it. Resting on this common underpinning are three specific complaints. The first two address what I take to be his implicit definitions of eating and of personhood, challenging his claims that it is possible in principle to separate self-regarding from other-regarding claims, and that purely self-regarding claims are not ethically relevant. The third pushes back on the matter of whether ethics must concern itself all and only with actions that have an impact on others.
