In this article, I argue for a distinct and novel right-based account of risks and I call it the Sophisticated High-risk Thesis. I argue that there is a distinction between rights-infringing risk impositions and no-rights-infringing risk impositions. An action imposing a high risk of harm infringes rights, whereas an act imposing a low risk of harm does not. I also suggest three principles that govern the permissibility of highly risky actions. If a highly risky action meets the conditions specified by (...) any of these three principles, it can be justified. These principles are the consent principle*, the prevent disaster principle* and the reciprocity principle**. I show that the Sophisticated High-risk Thesis is, in general, better than the alternative Risk Thesis defended by McCarthy. (shrink)

Deontological theories face difficulties in accounting for situations involving risk; the most natural ways of extending deontological principles to such situations have unpalatable consequences. In extending ethical principles to decision under risk, theorists often assume the risk must be incorporated into the theory by means of a function from the product of probability assignments to certain values. Deontologists should reject this assumption; essentially different actions are available to the agent when she cannot know that a certain act is in her (...) power, so we cannot simply understand her choice situation as a “risk-weighted” version of choice under certainty.

The paper addresses the nature of duties grounded in human rights. Rather than being protections against harm, per se, I contend that human rights largely shield against risk impositions to protected interests. “Risk imposition” is a normative idea requiring explication, but understanding dutiful action in its terms enables human rights to provide prospective policy guidance, hold institutions accountable, operate in non-ideal circumstances, embody impartiality among persons, and define the moral status of agencies in international relations. Slightly differently, I indicate a (...) general understanding of dutiful action that permits human rights to see to the tasks of an institutional morality. (shrink)

Within philosophy there has been little discussion of the risks associated with natural events such as earthquakes. The first objective of this paper is to demonstrate why such risks should be the subject of more sustained philosophical interest. We argue that we cannot simply apply to risks associated with natural events those insights and frameworks for moral evaluation developed in the literature considering ordinary risks, technological risks and the risks posed by anthropogenic climate change. The second objective of this paper (...) is to identify and develop a framework for the moral evaluation of the source of the risks associated with natural events, or the actions which sustain and impact such risks. Our discussion concentrates on the ways the construction and modification of built and natural environments can alter the probability of occurrence of natural events and the character and magnitude of the impact that such events have. We then argue for the need to develop a standard of reasonable care for decisions about the built and modified natural environment, which accounts for technical and resource constraints, as well as the place of natural hazard mitigation in public policy.

In this paper I examine the prospects for a rights-based approach to the morality of pure risk-imposition. In particular, I discuss a practical challenge to proponents of the thesis that we have a right against being imposed a risk of harm. According to an influential criticism, a right against risk-imposition will rule out all ordinary activities. The paper examines two strategies that rights theorists may follow in response to this “Paralysis Problem”. The first strategy introduces a threshold for when a (...) risk-imposition is a rights violation. The second strategy drops the claim that rights are absolute and maintains that all rights infringements generate compensation duties. It is argued that both strategies face significant practical problems of their own and that the Paralysis Problem seems fatal for a right against risk-imposition in the absence of an adequate account of the morally relevant threshold risk.

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)

The nonconsequentialist revival in tort theory has focused almost exclusively on one issue: showing that the rules governing compensation for acts reflect corrective justice rather than welfarist norms. The literature either is silent on what makes an act wrongful in the first place or suggests criteria that seem indistinguishable from some version of cost/benefit analysis. As a result, cost/benefit analysis is currently the only game in town for determining appropriate standards of conduct for socially useful but risky acts. This is (...) no small omission, and the failure of nonconsequentialists to acknowledge it or cure it can be traced to a number of recurring problems in the nonconsequentialist tort literature. Chief among them is the tendency to conflate prohibition and compensation, and to treat imposition of risk and imposition of harm as if they were distinct forms of conduct rather than the same conduct viewed from different temporal perspectives.

According to the purist war ethic, the killings committed by soldiers fighting in just wars are permissible, but those committed by unjust combatants are nothing but murders. Jeff McMahan asserts that purism is a direct consequence of the justice-based account of self-defence. I argue that this is incorrect: the justice-based conception entails that in many typical cases, killing unjust combatants is morally unjustified. So real purism is much closer to pacifism than its proponents would like it to be. I conclude (...) that the best explanation of the common view that unjust combatants may be defensively killed relies on a rights-based conception of self-defence. (shrink)

Many philosophers accept that, as well as having a right that others not harm us, we also have a right that others not subject us to a risk of harm. And yet, when we attempt to spell out precisely what this ‘right against risk imposition’ involves, we encounter a series of notorious puzzles. Existing attempts to deal with these puzzles have tended to focus on the nature of rights – but I propose an approach that focusses instead on the nature (...) of risk. The key move is to distinguish two different ways in which to conceptualise the risk that a given action presents – one of which is linked to the notion of probability and the other to the notion of normalcy.

Many argue that absolutist moral theories -- those that prohibit particular kinds of actions or trade-offs under all circumstances -- cannot adequately account for the permissibility of risky actions. In this dissertation, I defend various versions of absolutism against this critique, using overlooked resources from formal decision theory. Against the prevailing view, I argue that almost all absolutist moral theories can give systematic and plausible verdicts about what to do in risky cases. In doing so, I show that critics have (...) overlooked: (1) the fact that absolutist theories -- and moral theories, more generally -- underdetermine their formal decision-theoretic representations; (2) that decision theories themselves can be generalised to better accommodate distinctively absolutist commitments. Overall, this dissertation demonstrates that we can navigate a risky world without compromising our moral commitments. (shrink)
