Ex-Ante Prioritarianism Violates Sequential Ex-Ante Pareto

Prioritarianism is a variant of utilitarianism. It differs from utilitarianism in that benefiting individuals matters more the worse off these individuals are. On this view, there are two standard ways of handling risky prospects: Ex-Post Prioritarianism adjusts for prioritizing the worse off in final outcomes and then values prospects by the expectation of the sum total of those adjusted values, whereas Ex-Ante Prioritarianism adjusts for prioritizing the worse off on each individual's expectation and then values prospects by the sum total of those adjusted expectations. A standard objection to Ex-Post Prioritarianism is that it violates Ex-Ante Pareto, that is, it prescribes choices that worsen the expectations for everyone. In this article, I argue that Ex-Ante Prioritarianism suffers from much the same problem: it violates a sequential version of Ex-Ante Pareto, that is, it prescribes sequences of choices that worsen the expectations for everyone.

Does Abortion Harm the Fetus?

A central claim in abortion ethics is what might be called the Harm Claim – the claim that abortion harms the fetus. In this article, we put forward a simple and straightforward reason to reject the Harm Claim. Rather than invoking controversial assumptions about personal identity, or some nonstandard account of harm, as many other critics of the Harm Claim have done, we suggest that the aborted fetus cannot be harmed for the simple reason that it does not occupy any well-being level.

The Harm Principle and the Nature of Harm

This article defends the Harm Principle, commonly attributed to John Stuart Mill, against recent criticism. Some philosophers think that this principle should be rejected, because of severe difficulties with finding an account of harm to plug into it. I examine the criticism and find it unforceful. Finally, I identify a faulty assumption behind this type of criticism, namely that the Harm Principle is plausible only if there is a full-blown, and problem-free, account of harm, which proponents of the principle can refer to.

Who Authored On Liberty? Stylometric Evidence on Harriet Taylor Mill's Contribution

It is well known that John Stuart Mill (JSM) repeatedly acknowledges Harriet Taylor Mill's (HTM) substantial contribution to On Liberty. After her death, however, he decides to publish the book under his name only. Are we justified in continuing this practice, initiated by JSM, of refusing unequivocal co-authorship status to HTM? Drawing on stylometric analyses, we make a preliminary case that JSM did not write On Liberty all by himself and that HTM had a hand in formulating it. Drawing on plausible standards for authorship ascription, we further point out that authorship status requires, in addition to a substantial contribution, the approval by all contributors. We discuss potential reasons to assume that HTM did not approve the published version of On Liberty and would have objected to including her name on the title page.

Human Extinction and Moral Worthwhileness

In this article I make two main critiques of Kaczmarek and Beard's article ‘Human Extinction and Our Obligations to the Past’. First, I argue that there is an ambiguity in what it means to realise the benefits of a sacrifice and that this ambiguity affects the persuasiveness of the authors’ arguments and responses to various objections to their view. Second, I argue that their core argument against human extinction depends on an unsupported assumption about the existence and importance of existential benefits.

Climate Change and Non-Identity

What is the practical relevance of the Non-Identity Problem (NIP) for our climate change-related duties? Climate change and the NIP are often discussed together, but there is surprisingly little work on the practical relevance of the NIP for the ethics of climate change. The central claim of this article is that the NIP makes a relatively minor difference to our climate change-related duties even if we pursue what has become known as the ‘bite the bullet’ strategy: endorse a person-affecting view threatened by the NIP and not modify it in such a way as to evade the NIP. In particular I will argue that a harm-based view can justify the big-picture call for action emerging from the field of climate ethics. The key to reaching this conclusion is pointing out the consequences of our climate change-related decisions for people whose existence does not depend on these very decisions.

Limits to Aggregation and Uncertain Rescues

Limited aggregation holds that we are only sometimes, not always, permitted to aggregate. Aggregation is permissible only when the harms and benefits are relevant to one another. But how should limited aggregation be extended to cases in which we are uncertain about what will happen? In this article, I provide a challenge to ex post limited aggregation. I reconstruct a precise version of ex post limited aggregation that relies on the notion of ex post claims. However, building a theory of limited aggregation based on ex post claims leads to a dilemma. This shows that ex post limited aggregation is currently far away from being a well-defined alternative, strengthening the case for ex ante limited aggregation.
