Abstract

Deontologists are united in asserting that there are side-constraints on permissible action, prohibiting acts of murder, theft, infidelity, etc., even in cases where performing such acts would make things better overall from an impartial standpoint. These constraints are enshrined in the vocabulary of rights apply even when violating those constraints would lead to fewer constraint-violations overall: I am prohibited from killing an innocent even when doing so is the only way to prevent you from killing five. However, deontologists are divided over whether we have a duty to violate a smaller number of rights when this is necessary to prevent ourselves from later violating a larger number of rights that are at least as stringent. I argue that individuals do have such a duty, a duty which follows from widely accepted consistency constraints on choice.
