While Nozick and his sympathizers assume there is a widespread anti-hedonist intuition to prefer reality to an experience machine, hedonists have marshalled empirical evidence that shows such an assumption to be unfounded. Results of several experience machine variants indicate there is no widespread anti-hedonist intuition. From these findings, hedonists claim Nozick's argument fails as an objection to hedonism. This article suggests the argument surrounding experience machines has been misconceived. Rather than eliciting intuitions about what is prudentially valuable, these intuitive judgements are instead calculations about prudential pay-offs and trade-offs. This position can help explain the divergence of intuitions people have about experience machines.

Most of the literature on moral uncertainty has been oriented around the project of giving a normative theory for actions under moral uncertainty. The need for such a theory presupposes that internalist factors such as moral beliefs and evidence are relevant to what an agent ought to do. Some authors, including Elizabeth Harman, reject that presupposition. Harman advances an argument against all such internalist views on the grounds that they entail the exculpation of agents who should strike us as morally culpable. I argue that Harman's argument is only sound with respect to a small subset of internalist views, a subset that no one in fact defends. Though Harman's argument misses its mark, it raises important questions about how internalist theories should be understood. I argue that internalist theories should be understood as issuing rational, not moral, prescriptions.

Theories of well-being that give an important role to satisfied pro-attitudes need to account for the fact that, intuitively, the scope of possible objects of pro-attitudes seems much wider than the scope of things, states or events that affect our well-being. Parfit famously illustrated this with his wish that a stranger may recover from an illness: it seems implausible that the stranger's recovery would constitute a benefit for Parfit. There is no consensus in the literature about how to rule out such well-being-irrelevant pro-attitudes. I argue, first, that there is no distinction in kind between well-being-relevant and irrelevant pro-attitudes. Instead, well-being-irrelevant pro-attitudes are the limiting cases on the scale measuring how much of a difference pro-attitudes make to the subject's well-being. Second, I propose a particular scalar model according to which the well-being-relevance of pro-attitudes is measured either by their hedonic tone, or by the subject's conative commitment.

It is widely thought that moral obligations are necessarily guidance giving. This supposed fact has been put to service in defence of the ‘ought-implies-can’ principle according to which one cannot be morally obligated to do the impossible, since impossible-to-satisfy obligations would not give guidance. It is argued here that the supposed fact is no such thing; moral obligations are not necessarily guiding giving, and so the ‘guidance argument’ for ought-implies-can fails.

Rule-Consequentialism faces ‘the problem of partial acceptance’: How should the ideal code be selected given the possibility that its rules may not be universally accepted? A new contender, ‘Calculated Rates’ Rule-Consequentialism claims to solve this problem. However, I argue that Calculated Rates merely relocates the partial acceptance question. Nevertheless, there is a significant lesson from this failure of Calculated Rates. Rule-Consequentialism's problem of partial acceptance is more helpfully understood as an instance of the broader problem of selecting the ideal code given various assumptions – assumptions about who will accept and comply with the rules, but also about how the rules will be taught and enforced, and how similar the future will be. Previous rich discussions about partial acceptance provide a taxonomy and groundwork for formulating the best version of Rule-Consequentialism.

Ben Bramble, Dan Haybron and others have endorsed the idea that there are unconscious, or unfelt, pleasures and pains. These would be sensory experiences that are genuine pleasures or pains, but experiences of which the subject is unaware. The idea that there are such things is worthy of attention in its own right; but I am interested in this alleged phenomenon for a further reason. I am attracted to an attitudinal theory of sensory pleasure and pain. Bramble has claimed that the existence of unconscious pleasures and pains reveals that attitudinal theories cannot be true. Chris Heathwood has offered a reply on behalf of attitudinalism. I think a better reply can be provided. In this article I explain why an attitudinal theory of pleasure and pain is consistent with whatever is plausible in the ‘unconscious pleasure and pain’ phenomenon.

If ‘F’ is a predicate, then ‘Fer than’ or ‘more F than’ is a corresponding comparative relational predicate. Concerning such comparative relations, John Broome's Collapsing Principle states that, for any x and y, if it is false that y is Fer than x and not false that x is Fer than y, then it is true that x is Fer than y. Luke Elson has recently put forward two counter-examples to this principle, allegedly showing that it yields contradictions if there are borderline cases. In this article, I argue that the Collapsing Principle does not rule out borderline cases, but I also argue that the principle is implausible.
