According to the person-affecting restriction, one distribution of welfare can be better than another only if there is someone for whom it is better. Extant problems for the person-affecting restriction involve variable-population cases, such as the nonidentity problem, which are notoriously controversial and difficult to resolve. This paper develops a fixed-population problem for the person-affecting restriction. The problem reveals that, in the presence of incommensurable welfare levels, the person-affecting restriction is incompatible with minimal requirements of impartial beneficence even in fixed-population (...) contexts.

This thesis in an invistigation into the concept of "harm" and its moral relevance. A common view is that an analysis of harm should include a counterfactual condition: an act harms a person iff it makes that person worse off. A common objection to the moral relevance of harm, thus understood, is the non-identity problem. -/- This thesis criticises the counterfactual condition, argues for an alternative analysis and that harm plays two important normative roles. -/- The main ground for rejecting (...) the counterfactual condition is that it has unacceptable consequences in cases of overdetermination and pre-emption. Several modifications to the condition are considered but all fail to solve this problem. -/- According to the alternative analysis to do harm is to perform an act which is responsible for the obtaining of a state of affairs which makes a person’s life go worse. It is argued that should be understood in terms of counterfactual dependence. This claim is defended against counterexamples based on redundant causation. An analysis of is also provided using the notion of a well-being function. It is argued that by introducing this notion it is possible to analyse contributive value without making use of counterfactual comparisons and to solve the non-identity problem. -/- Regarding the normative importance of harm, a popular intuition is that there is an asymmetry in our obligations to future people: that a person would have a life worth living were she to exist is not a reason in favour of creating that person while that a person would have a life not worth living is a reason against creating that person. It is argued that the asymmetry can be classified as a moral option grounded in autonomy. Central to this defence is the suggestion that harm is relevant to understanding autonomy. Autonomy involves partly the freedom to pursue one’s own aims as long as one does no harm. (shrink)

The Procreation Asymmetry holds that we have strong moral reasons not to create miserable people for their own sakes, but no moral reasons to create happy people for their own sakes. To defend this conjunction against an argument that it leads to inconsistency, I show how recognizing ‘creation’ as a temporally extended process allows us to revise the conjuncts in a way that preserves their intuitive force. This defense of the Procreation Asymmetry is preferable to others because it does not (...) require us to take on controversial metaphysical or metaethical commitments – in other words, it has the theoretical virtue of portability.

Theories of intergenerational justice are a very common and popular way to conceptualise the obligations currently living people may have to future generations. After briefly pointing out that these theories presuppose certain views about the existence, number and identity of future people, I argue that the presuppositions must themselves be ethically investigated, and that theories of intergenerational justice lack the theoretical resources to be able to do this. On that basis, I claim it is necessary to do the ‘ethics of (...) metaphysics’ in order to fully comprehend what, if anything, we may owe future generations. I defend these claims against some important objections. (shrink)

In his book Reasons and Persons, Derek Parfit suggests that people are not harmed by being conceived with a disease or disability if they could not have existed without suffering that particular condition. He nevertheless contends that entities can be harmed if the suffering they experience is sufficiently severe. By implication, there is a threshold which divides harmful from non-harmful conceptions. The assumption that such a threshold exists has come to play a part in UK policy making. I argue that (...) Parfit’s distinction between harmful and non-harmful conceptions is untenable. Drawing on Kant’s refutation of the ontological argument for God’s existence, I suggest that the act of creation cannot be identical with the act of harming—nor indeed of benefiting—however great the offspring’s suffering may be. I suggest that Parfit is right that bringing children into existence does not usually harm them, but I argue that this must be applied to all conceptions, since Parfit cannot show how the harm threshold can be operationalised. If we think certain conceptions are unethical or should be illegal, this must be on other grounds than that the child is harmed by them. I show that a Millian approach in this context fails to exemplify the empirical and epistemological advantages which are commonly associated with it, and that harm-based legislation would need to be based on broader harm considerations than those relating to the child who is conceived.

While different worries about population size are present in public debates, political philosophers often take population size as given. This paper is an attempt to formulate a Rawlsian liberal egalitarian approach to population size: does it make sense to speak of ‘too few’ or ‘too many’ people from the point of view of justice? It argues that, drawing on key features of liberal egalitarian theory, several clear constraints on demographic developments – to the extent that they are under our control (...) – can be formulated. Based on these claims, we can clarify both the grounds and content of our obligations to future generations. (shrink)

Expectations play an important role in how people plan their lives and pursue their projects. People living in highly industrialized countries share a way of life that comes with high levels of emissions. Their expectations to be able to continue their projects imply their holding expectations to similarly high future levels of personal emissions. We argue that the frustration or undermining of these expectations would cause them significant harm. Further, the article investigates under what conditions people can be thought to (...) hold legitimate expectations, in particular about permissible levels of future emissions. We distinguish differing theories of understanding these conditions, namely authority-based and justice-based theories, that each allows us to systematically distinguish between legitimate and illegitimate expectations. Furthermore, with respect to individuals’ future permissible emissions we give several reasons for holding that such theories cannot identify a particular expectation to a specific level of personal emissions as the only legitimate one. Finally, we argue that the set of legitimate expectations that people hold with respect to a just and effective solution to climate change has normative significance in at least two ways: the differing but equally legitimate expectations ought to be taken into account when justifying what could count as such a solution and when determining the just way of arriving at and implementing such a solution.
