In the first two volumes of On What Matters,1 Derek Parfit pursued a conciliatory project in normative ethics, which sought to dissolve the disagreement between the most plausible versions of Kantianism, contractualism and rule consequentialism. Parfit was less conciliatory in his meta-ethics, however. Does Parfit’s conciliatory project in metaethics succeed? We shall begin to address this question in the next section by, first, trying to get a grip on Parfit’s position, which now goes by the name ‘non-realist cognitivism’, and, second, by examining his account of properties, and of normative properties in particular. We shall then examine whether Parfit’s triviality objection is effective against Jackson’s brand of naturalism. Finally, we will ask whether Parfit is right to think that his favoured metaethical view converges with what he thinks are the most plausible forms of naturalism and quasirealism,illustrated by Railton’s view and Gibbard’s view, respectively.

In his recent book, Michael Zimmerman continues to defend the Prospective View, according to which moral obligation depends on evidence about both empirical and evaluative factors. In my commentary, I shall first focus on Zimmerman’s framework in which different moral theories are defined and distinguished. I argue that Zimmerman fails to formulate a clear and coherent distinction between The Prospective View and the Objective View, which he rejects. Then I turn to the so-called constraint #2, a crucial premise in Zimmerman’s master argument against the Objective View. Here I argue that it should be given up so that we can give the right verdict in cases of fundamental moral uncertainty. More specifically, I shall argue that a morally conscientious agent can rationally choose the option that is guaranteed to be morally wrong in a Jackson-case of fundamental moral uncertainty. Finally, I shall argue that the Prospective View, in its most recent guise – according to which moral obligation depends on empirical and evaluative evidence the agent has actually availed herself of – has very troubling substantive implications that go against all traditional moral theories, as well as an earlier version of Zimmerman’s Prospective View.

We talk about what we have moral, rational or prudential reason to do. We also talk about what we have moral reason to feel and desire and what we have epistemic reason to believe or accept. In all these debates, we often say that one reason is stronger or weightier than another. This book aims to elucidate this reason-talk, especially the talk about the weight or strength of reasons. Seventeen philosophers, if we include the two editors who have written an informative introduction, are having a go at clarifying important issues about reasons. These issues range from analytical questions about: the meaning of the terms ‘reason’ as mass noun and ‘reasons’ as a count noun,...

What is the prudentially right thing to do in situations in which our actions will shape our preferences? Suppose, for instance, that you are considering getting married, and that you know that if you get married, you will prefer being unmarried, and that if you stay unmarried, you will prefer being married. This is the problem I will deal with in this article. I will begin by explaining why preferences matter to prudence. I will then go on to discuss a couple of unsuccessful theories and see what we can learn from their mistakes. One of the most important lessons is that how you would have felt about a life had you never led it is irrelevant to the question of what you prudentially ought to do. My theory takes this into account. What counts is how you feel about a life when you are actually leading it. (Published Online August 21 2006).

Desire-based theories of well-being are often said to accept (G), x is good for a person just in case he wants it, and (B), x is better for a person than y just in case he prefers x to y. I shall argue that (G) and (B) are inconsistent, and this inconsistency resists any plausible refinement of these principles. The inconsistency is brought out by cases in which our wants and preferences for certain life-options are contingent on which life-option we realize. My argument can be generalized to endorsement theories that define a person’s good as the right combination of some kind of objective desirability and subjective endorsement, and allow preferences to be tie-breakers when the compared objects are equally desirable (or incommensurable). My conclusions will not just be negative. I shall argue that if the choice is between (G) and (B), the most attractive option is to keep (G), slightly refined, and drop (B).

Michael Smith has recently argued that non-cognitivists are unable to accommodate crucial structural features of moral belief, and in particular that non-cognitivists have trouble accounting for subjects' certitude with respect to their moral beliefs. James Lenman and Michael Ridge have independently constructed 'ecumenical' versions of non-cognitivism, intended to block this objection. We argue that these responses do not work. If ecumenical non-cognitivism, a hybrid view which incorporates both non-cognitivist and cognitivist elements, fails to meet Smith's challenge, it is unlikely that 'purer' and more familiar versions of non-cognitivism will succeed.

The simple idea behind act-consequentialism isthat we ought to choose the action whoseoutcome is better than that of any alternativeaction. In a recent issue of this journal, ErikCarlson has argued that given a reasonableinterpretation of alternative actions thissimple idea cannot be upheld but that the newtheory he proposes nevertheless preserves theact-consequentialist spirit. My aim in thispaper is to show that Carlson is wrong on bothcounts. His theory, contrary to his ownintentions, is not an act-consequentialisttheory. By building on a theory formulated byHolly Smith, I will show that the simple ideacan be upheld. The new theory I will proposehas all the merits of Carlson's theory withoutsharing its demerits.

What should we do when we are not certain about what we morally should do? There is a long history of theorizing about decision-making under empirical uncertainty, but surprisingly little has been written about the moral uncertainty expressed by this question. Only very recently have philosophers started to systematically address the nature of such uncertainty and its impacts on decision-making. This paper addresses the main problems raised by moral uncertainty and critically examines some proposed solutions.

I am grateful to have been given the opportunity to comment on McKerlie's interesting article, especially since it concerns one of my pet topics and provides many helpful comments on one of my own articles on this topic. My comments will be brief because I agree with most of his points, in particular, his criticisms of the prudential view and the present-aim theory. What I want to do here is just to clarify a couple of things concerning my own theory, concede some of the difficulties that McKerlie raises for my theory, and see to what extent his own proposal fares better than my own theory.

Act-consequentialism is usually taken to be the view that we ought to perform the act that will have the best consequences. But this definition ignores the possibility of various non-maximizing forms of act-consequentialism, e.g. satisficing theories that tell us to perform the act whose consequences will be good enough. What seems crucial to act-consequentialism is not that we ought to maximize value but that the normative status of alternative actions depends solely on the values of their outcomes. The purpose of this paper is to spell out this dependency claim and argue that it should be seen as the denning feature of act-consequentialism. In particular, I will defend the definition against certain objections that purport to show that the definition is too wide and too narrow

Accommodating degrees of moral certitude is a serious problem for non-cognitivism about ethics. In particular, non-cognitivism has trouble accommodating fundamental moral certitude. John Eriksson and Ragnar Francén Olinder [2016] have recently proposed a solution. In fact, Eriksson and Francén Olinder offer two different proposals—one ‘classification’ account and one ‘projectivist’ account. We argue that the classification account faces the same problem as previous accounts do, while the projectivist account has unacceptable implications. Non-cognitivists will have to look elsewhere for a plausible solution to the problem of accommodating fundamental moral certitude.

How do we determine the well-being of a person when her preferences are not stable across worlds? Suppose, for instance, that you are considering getting married, and that you know that if you get married, you will prefer being unmarried, and that if you stay unmarried, you will prefer being married. The general problem is to find a stable standard of well-being when the standard is set by preferences that are not stable. In this paper, I shall show that the problem is even worse: inconsistency threatens if we accept both that your desires determine what is good for you and that you must prefer what is better for you. After I have introduced a useful toy model and stated the inconsistency argument, I will go on to discuss a couple of unsuccessful theories and see what we can learn from their mistakes. One important lesson is that how you would have felt about a life had you never led it is irrelevant to the question of how good that life is for you. What counts is how you feel about your life when you are actually leading it. Another lesson is that a life can be better for you even if you would not rank it higher, if you were to lead it.

John Broome's Weighing Lives provides a much-needed framework for the intriguing problems of population ethics. It is also an impressive attempt to find a workable solution to these problems. I am not sure that Broome has found the right solution, but I think he has done the ethics profession a tremendous service in tidying up the discussion. The framework he presents will make it possible for the participants in this debate to formulate their positions in a clear and precise manner. Even people who disagree with him will be helped by this framework, since they will now be able to show exactly where their views differ.

It has been proved to be extremely difficult to find a theory of beneficence that would provide both a coherent and plausible account of our responsibilities to future generations. Matters seem to be even worse if we adopt a desire-based theory of well-being. If we assume that the well-being of a person crucially depends on how well her preferences are satisfied, then we need to worry not only about which persons to create, but also which desires to create. A satisfactory desire-theory, it is argue here, must define what is better for a person in terms of his absolute desires, not his comparative ones, and discriminate between desires on the basis of the values of their objects.
