Theories of rights seem well equipped to explain widely accepted claims about the morality of harming. But can they explain popular claims about the morality of imposing risks of harm? Many think not. But a plausible theory of rights can explain those claims if it says we have the right that others not impose risks of harm upon us. That is a good reason to believe we have that right. There are many objections to the claim that we have that (...) right, but none of them are sound. Among the topics covered are: the permissibility of rights infringements, trivial rights infringements, the permissibility of risk impositions, the aggregation of rights, consent, self-defense, punishment, and compensation.
