How wrong is it to deceive someone into sex by lying, say, about one's profession? The answer is seriously wrong when the liar's actual profession would be a deal breaker for the victim of the deception: this deception vitiates the victim's sexual consent, and it is seriously wrong to have sex with someone while lacking his or her consent.

You are morally permitted to save your friend at the expense of a few strangers, but not at the expense of very many. However, there seems no number of strangers that marks a precise upper bound here. Consequently, there are borderline cases of groups at the expense of which you are permitted to save your friend. This essay discusses the question of what explains ethical vagueness like this, arguing that there are interesting metaethical consequences of various explanations.

In an influential paper, L. A. Paul argues that one cannot rationally decide whether to have children. In particular, she argues that such a decision is intractable for standard decision theory. Paul's central argument in this paper rests on the claim that becoming a parent is ``epistemically transformative''---prior to becoming a parent, it is impossible to know what being a parent is like. Paul argues that because parenting is epistemically transformative, one cannot estimate the values of the various outcomes of (...) a decision whether to become a parent. In response, we argue that it is possible to estimate the value of epistemically transformative experiences. Therefore, there is no special difficulty involved in deciding whether to undergo epistemically transformative experiences. Insofar as major life decisions do pose a challenge to decision theory, we suggest that this is because they often involve separate, familiar problems. (shrink)

The anglophone philosophy profession has a well-known problem with gender equity. A sig-nificant aspect of the problem is the fact that there are simply so many more male philoso-phers than female philosophers among students and faculty alike. The problem is at its stark-est at the faculty level, where only 22% - 24% of philosophers are female in the United States (Van Camp 2014), the United Kingdom (Beebee & Saul 2011) and Australia (Goddard 2008).<1> While this is a result of the (...) percentage of women declining at each point through-out the standard career trajectory, recent large-scale studies in the United States (Paxton et al. 2012) and Australia (Goddard et al. 2008) have identified a key drop-off point as the transi-tion between taking introductory classes and majoring in philosophy. So why do dispropor-tionately few female students choose to major in philosophy? (shrink)

According to the “Textbook View,” there is an extensional dispute between consequentialists and deontologists, in virtue of the fact that only the latter defend “agent-relative” principles—principles that require an agent to have a special concern with making sure that she does not perform certain types of action. I argue that, contra the Textbook View, there are agent-neutral versions of deontology. I also argue that there need be no extensional disagreement between the deontologist and consequentialist, as characterized by the Textbook View.

Nearly everyone prefers pain to be in the past rather than the future. This seems like a rationally permissible preference. But I argue that appearances are misleading, and that future-biased preferences are in fact irrational. My argument appeals to trade-offs between hedonic experiences and other goods. I argue that we are rationally required to adopt an exchange rate between a hedonic experience and another type of good that stays fixed, regardless of whether the hedonic experience is in the past or (...) future.

Why is there female under-representation among philosophy majors? We survey the hypotheses that have been proposed so far, grouping similar hypotheses together. We then propose a chronological taxonomy that distinguishes hypotheses according to the stage in undergraduates’ careers at which the hypotheses predict an increase in female under-representation. We then survey the empirical evidence for and against various hypotheses. We end by suggesting future avenues for research.

Most of us are “time-biased” in preferring pains to be past rather than future and pleasures to be future rather than past. However, it turns out that if you are risk averse and time-biased, then you can be turned into a “pain pump”—in order to insure yourself against misfortune, you will take a series of pills which leaves you with more pain and better off in no respect. Since this vulnerability seems rationally impermissible, while time-bias and risk aversion seem rationally (...) permissible, we are left with a puzzle. (shrink)

It is plausible to think that it is wrong to cure many people’s headaches rather than save someone else’s life. On the other hand, it is plausible to think that it is not wrong to expose someone to a tiny risk of death when curing this person’s headache. I will argue that these claims are inconsistent. For if we keep taking this tiny risk then it is likely that one person dies, while many others’ headaches are cured. In light of (...) this inconsistency, there is a conflict in our intuitions about beneficence and chance. This conflict is perplexing. And I have not been able to find a satisfactory way of resolving it. Perhaps you can do better? (shrink)

In Wrongs and Crimes, Victor Tadros clarifies the debate about whether consent needs to be communicated by separating the question of whether consent requires expressive behaviour from the question of whether it requires “uptake” in the form of comprehension by the consent-receiver. Once this distinction is drawn, Tadros argues both that consent does not require uptake and that consent does not require expressive behaviour that provides evidence to the consent-receiver. As a result, Tadros takes the view that consent requires an (...) attempt to communicate, but nothing more. While I have found Tadros’s arguments for this conclusion intriguing and challenging, I am yet to be persuaded by them. In this essay, I try to say why. (shrink)

So-called money pump arguments aim to show that intransitive preferences are irrational because they will lead someone to accept a series of deals that leaves his/her financially worse off and better off in no respect. A common response to these arguments is the foresight response, which counters that the agent in question may see the exploitation coming, and refuse to trade at all. To obviate this response, I offer a “deluxe money pump argument” that applies dominance reasoning to a modified (...) money pump case. (shrink)

Why is consent revocable? In other words, why must we respect someone's present dissent at the expense of her past consent? This essay argues against act-based explanations and in favor of a rule-based explanation. A rule prioritizing present consent will serve our interests the best, in light of our interests in having flexibility over our consent and in minimizing the possibility of error in people's judgments about whether we consent.

This chapter discusses vagueness in ethics.

You ought to save a larger group of people rather than a distinct smaller group of people, all else equal. A consequentialist may say that you ought to do so because this produces the most good. If a non-consequentialist rejects this explanation, what alternative can he or she give? This essay defends the following explanation, as a solution to the so-called numbers problem. Its two parts can be roughly summarised as follows. First, you are morally required to want the survival (...) of each stranger for its own sake. Secondly, you are rationally required to achieve as many of these ends as possible, if you have these ends. (shrink)

A classic objection to act-consequentialism is that it is overdemanding: it requires agents to bear too many costs for the sake of promoting the impersonal good. I develop the complementary objection that act-consequentialism is underdemanding: it fails to acknowledge that agents have moral reasons to bear certain costs themselves, even when it would be impersonally better for others to bear these costs.

Moral indeterminacy can be problematic: prospectively it can give rise to deliberative anguish, and retrospectively, it can leave us in a limbo as to what attitudes it is appropriate to form with respect to past actions with indeterminate moral status. These problems give us reason to resolve ethical indeterminacy. One mechanism for doing so involves the use of our normative powers to place obligations on ourselves and to waive our claims against others. This mechanism could operate through an explicit agreement, (...) but could also operate through implicit endorsement of a social convention. However, there are important limits on when the mechanism can eliminate moral indeterminacy. (shrink)
