Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

I want to focus on some of the limits of decision theory that are of interest to the philosophical concern with practical reasoning and rational choice. These limits should also be of interest to the social-scientists’ concern with Rational Choice.

It seems natural to choose whether to have a child by reflecting on what it would be like to actually have a child. I argue that this natural approach fails. If you choose to become a parent, and your choice is based on projections about what you think it would be like for you to have a child, your choice is not rational. If you choose to remain childless, and your choice is based upon projections about what you think it (...) would be like for you to have a child, your choice is not rational. This suggests we should reject our ordinary conception of how to make this life-changing decision, and raises general questions about how to rationally approach important life choices. (shrink)

In this paper, I argue that cases of radical selftransformation (cases in which an agent willfully changes a foundational element of their motivational structure) constitute an important philosophical puzzle. Though our inclination to hold people responsible for such changes suggests that we regard radical transformation as (in some sense) self-determined, it is difficult to conceive how a transformation that extends to the heart of an agent’s practical life can be attributed to the agent at all. While I contend that the (...) best way to solve this puzzle is to deny that radical transformations are in fact self-determined, many maintain the opposite. The defense of my thesis involves showing how the conditions that must be met in order to coherently attribute transformation to an agent are not satisfied in cases of radical transformation. Radical transformation is, thus, something that happens to an agent, not something that is done by her. (shrink)

The incomparability of two items is thought to pose a problem for making justified choices and for consequentialist theories that rely on comparing states of the world to judge the goodness of a particular course of action. In response, it has been argued that items thought incomparable by one of the three standard relations, ‘better than’, ‘worse than’ and ‘equally good’, are instead comparable by some fourth relation, such as ‘roughly equal’ or ‘on a par’. Against such accounts, this article (...) argues that values in virtue of which comparisons are made can be ‘clumpy’ and that in comparisons involving clumpy values, we have no reason to accept ‘roughly equal’ or ‘on a par’ as distinct from ‘equally good’. The article supports the possibility of incomparability by arguing for an interpretation of incomparability as an instance of incommensurability. (shrink)

Thomas Hill, a leading figure in the recent development of Kantian moral philosophy, presents a set of essays exploring the implications of basic Kantian ideas for practical issues. The first part of the book provides background in central themes in Kant's ethics; the second part discusses questions regarding human welfare; the third focuses on moral worth-the nature and grounds of moral assessment of persons as deserving esteem or blame. Hill shows moral, political, and social philosophers just how valuable moral theory (...) can be in addressing practical matters. (shrink)

Some experiences are transformative in that it is impossible to imagine experiencing them until one experiences them. It has been argued that pregnancy and parenthood are like that, and that therefore one cannot make a rational decision whether to become a mother. I argue that pregnancy and parenthood are not like that; but that if even if they are, a woman can still make a rational decision by relying on testimony about the value of these experiences. I then discuss an (...) objection that such testimony will be unreliable because parents will reflect on their being glad that their children exist, and will not realize that it’s reasonable to be glad their children exist even if the parents’ lives are thereby worse. I argue that despite this possible route to unreliable testimony, in general it is reasonable to rely on others’ testimony about the value of their lives. (shrink)

This paper argues for the existence of a fourth positive generic value relation that can hold between two items beyond ‘better than’, ‘worse than’, and ‘equally good’: namely ‘on a par’.

This paper presents an argument against the widespread view that ‘hard choices’ are hard because of the incomparability of the alternatives. The argument has two parts. First, I argue that any plausible theory of practical reason must be ‘comparativist’ in form, that is, it must hold that a comparative relation between the alternatives with respect to what matters in the choice determines a justified choice in that situation. If comparativist views of practical reason are correct, however, the incomparabilist view of (...) hard choices should be rejected. Incomparabilism about hard choices leads us to an implausible error theory about the phenomenology of hard choices, threatens an unattractive view of human agency, and leaves us in perplexity about what we are doing when we choose in hard choices. The second part of the argument explores the main competitor to comparativist views of practical reason, noncomparativist view, according tow which a choice is justified so long as it is not worse than any of the alternatives. This view is often assumed by rational choice theorists but has its best philosophical defense in work by Joseph Raz. On Raz’s view, incomparabilism about hard choices avoids the problems faced if comparativism is correct, but it faces different difficulties. I argue that Raz’s noncomparativist view mistakenly assimilates practical reason to more restricted normative domains such as the law. (shrink)

In virtue of what is something a reason for action? That is, what makes a consideration a reason to act? This is a metaphysical or meta-normative question about the grounding of reasons for action. The answer to the grounding question has been traditionally given in ‘pure’, univocal terms. This paper argues that there is good reason to understand the ground of practical normativity as a hybrid of traditional ‘pure’ views. The paper 1) surveys the three leading ‘pure’ answers to the (...) question of a normative ground, 2) examines one or two of the most difficult problems for each, proposing along the way a new objection to one, and 3) argues that a particular hybrid view about normative grounds –‘hybrid voluntarism’ – avoids each of the main problems faced by the three leading ‘pure’ views.

This chapter argues that there is a particular kind of ‘internal’ commitment typically made in the context of romantic love relationships that has striking meta-normative implications for how we understand the role of the will in practical normativity. Internal commitments cannot plausibly explain the reasons we have in committed relationships on the usual model—as triggering reasons that are already there, in the way that making a promise triggers a reason via a pre-existing norm of the form ‘If you make a (...) promise to x, then you have a reason to x’. Instead, internal commitments are that in virtue of which one has the special reasons of committed relationships; they are the grounds of such reasons. In this way, the will is a source of practical normativity. (shrink)

In this paper, I argue that whether, how, and to what extent an experience is transformative is often highly contingent. I then further argue that sometimes social conditions are a major factor in whether a certain type of experience is often or typically transformative. Sometimes social conditions make it easy for a type of experience to be transformative, and sometimes they make it hard for a type of experience to be transformative. This, I claim, can sometimes be a matter of (...) social justice: social conditions can make transformativeness too easy or too hard, in a way that harms people. (shrink)

Ethical concepts are, or purport to be, normative. They make claims on us: they command, oblige, recommend, or guide. Or at least when we invoke them, we make claims on one another; but where does their authority over us - or ours over one another - come from? Christine Korsgaard identifies four accounts of the source of normativity that have been advocated by modern moral philosophers: voluntarism, realism, reflective endorsement, and the appeal to autonomy. She traces their history, showing how (...) each developed in response to the prior one and comparing their early versions with those on the contemporary philosophical scene. Kant's theory that normativity springs from our own autonomy emerges as a synthesis of the other three, and Korsgaard concludes with her own version of the Kantian account. Her discussion is followed by commentary from G. A. Cohen, Raymond Geuss, Thomas Nagel, and Bernard Williams, and a reply by Korsgaard. (shrink)

How should we make choices when we know so little about our futures? L. A. Paul argues that we must view life decisions as choices to make discoveries about the nature of experience. Her account of transformative experience holds that part of the value of living authentically is to experience our lives and preferences in whatever ways they evolve.

This study uses techniques from economics to illuminate fundamental questions in ethics, particularly in the foundations of utilitarianism. Topics considered include the nature of teleological ethics, the foundations of decision theory, the value of equality and the moral significance of a person's continuing identity through time.

This paper investigates two puzzles in practical reason and proposes a solution to them. First, sometimes, when we are practically certain that neither of two alternatives is better than or as good as the other with respect to what matters in the choice between them, it nevertheless seems perfectly rational to continue to deliberate, and sometimes the result of that deliberation is a conclusion that one alternative is better, where there is no error in one’s previous judgment. Second, there are (...) striking differences between rational agents – some rational agents have most reason to pursue careers on Wall Street while others have most reason to take up a career in teaching, or scuba diving, or working for political causes. These differences aren’t plausibly explained by ‘passive’ facts about our psychology or their causal interaction with our environment; instead, these facts seem in some sense to ‘express who we are’. But what is this sense? These puzzles disappear if we adopt a novel view about the source of the normativity of reasons – some reasons are given to us and others are reasons in virtue of an act of will. We make certain considerations reasons through an act of will and thus sometimes make it true through an act of agency that we have most reason to do one thing rather than another. (shrink)

What theory should we accept from the practical point of view, or accept as a basis for guiding our actions, if we don’t know which theory is true, and if there are too many plausible alternative theories for us to take them all into consideration? This question is the theme of the first three parts of this dissertation. I argue that the problem of theory acceptance, so understood, is a problem of practical rationality, and hence that the appropriate grounds for (...) theory acceptance are practical considerations. I argue for a number of principles of theory acceptance, and I explore the implications of these principles for the acceptance both of descriptive theories and evaluative theories. (shrink)

What makes a choice difficult, beyond being complex or difficult to calculate? Characterizing difficult choices as posing a special challenge to the agent, and as typically involving consequences of significant moment as well as clashes of values, the article proceeds to compare the way difficult choices are handled by rational choice theory and by the theory that preceded it, Kurt Lewin's "conflict theory." The argument is put forward that within rational choice theory no choice is in principle difficult: if the (...) object is to maximize some value, the difficulty can be at most computational. Several prototypes of choices that challenge this argument are surveyed and discussed ; special attention is given to difficult choices faced by doctors and layers. The last section discusses a number of devices people employ in their attempt to cope with difficult choices: escape, "reduction" to non-difficult choices, and second-order strategies. (shrink)
