Abstract

Ng and singer derive the principle of utility from the fact of finite sensibility and another principle, weak majority preference: "for a community of n individuals choosing between two possibilities, x and y, if no individual prefers y to x, and at least n/2 individuals prefer x to y, then x increases social welfare and is preferable." this derivation is regarded as incorrect in a comment. this reply explains why the derivation is valid and shows that the comment is based on confusing a general social ordering with a utilitarian one
