Abstract

Notwithstanding the numerous errors in this piece, the core teaching remains unscathed: Arithmetic (or any other branch of mathematics) cannot do moral work. If it appears otherwise, that simply means some nonstandard version of the relevant area of mathematics will work. -/- Negative results can indeed sometimes be shown using mathematics, but not on such fundamental normative questions as whether something/someone has rights. Also, mathematics can put into relief, sometimes, a fundamental normative question, even though it cannot resolve it.
