Mainstream moral theories deal with situations in which the outcome of each possible action is well-determined and knowable. In order to make ethics relevant for problems of risk and uncertainty, moral theories have to be extended so that they cover actions whose outcomes are not determinable beforehand. One approach to this extension problem is to develop methods for appraising probabilistic combinations of outcomes. This approach is investigated and shown not to solve the problem. An alternative approach is then developed. Its (...) starting-point is that everyone has a prima facie moral right not to be exposed to risk. However, this right can be overridden if the risk-exposure is part of an equitable system for risk-taking that works to the advantage of the individual risk-exposed person. (shrink)

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.

The article investigates the resources of contractualist moral theory to make sense of the ethics of risk imposition. In some ways, contractualism seems well placed to explain how it can be reasonable to accept exposure to risk of harms whose direct imposition would not be acceptable. However, there are difficulties getting clear about what directness comes to here, especially given the difficulty of adequately motivating traditional views that assign ethical significance to what the agent intends as opposed to merely foreseeing. (...) The article considers two principles which might help the contractualist: the Redistribution Principle, which, while attractive, is perhaps somewhat too restrictive, and the Aim Consistency Principle, which grants ethical significance to the aims with which our actions are in principle consistent whatever our actual intentions may be. The article also considers the relative significance of ex ante and ex post perspectives from which to evaluate actions and principles.
