Abstract
This chapter compares a system of human rights guarantees of security with libertarian natural rights. Security rights are a solution to a collective action problem that would arise in a state of nature with libertarian natural rights, the internal security problem. To be endorsed by the main principle, a solution to that problem requires guarantees of procedural rights, which have no analog in natural rights. The chapter discusses various problems that have been thought to be fatal to consequentialism: the problem of intentionally punishing the innocent, and the related problem of inadvertently punishing the innocent, which is a challenging one for nonconsequentialists; strict criminal liability; and organ harvesting. The discussion of inadvertently punishing the innocent leads to a consideration of the doctrine of double effect. The chapter concludes the chapter with a comparison of his account with Judith Thomson’s trade-off idea, illustrated by the trolley cases.
