In recent years, a number of new trends have seen light at the intersection of semantics and philosophy of language. They are meant to address puzzles raised by the context-sensitivity of a variety of natural language constructions, such as knowledge ascriptions, belief reports, epistemic modals, indicative conditionals, quantifier phrases, gradable adjectives, temporal constructions, vague predicates, moral predicates, predicates of personal taste. A diversity of labels have consequently emerged, such as 'contextualism', 'indexicalism', 'invariantism', 'literalism', 'minimalism', and 'relativism', variously qualified. The goal (...) of this essay is to pinpoint the issues that lie at the heart of the recent debates, clarify what is at stake, and provide a snapshot of the current theoretical landscape. (shrink)

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.

In “What you can’t expect when you’re expecting,” I argue that, if you don’t know what it’s like to be a parent, you cannot make this decision rationally—at least, not if your decision is based on what you think it would be like for you to become a parent. My argument hinges on the idea that becoming a parent is a transformative experience. This unique type of experience often transforms people in a deep and personal sense, and in the process, (...) changes their preferences. In section 1, I will explain transformative experience in terms of radical first-personal epistemic and self change. In section 2, I’ll explain the notion of subjective value that I use to develop the decision problem. In section 3, I will discuss the way we ordinarily combine our introspective assessments with testimony and evidence. In section 4, I will discuss the problems for rational decision-making. In section 5, I will explore the problem of first-personally transformed future selves. In section 6, I will engage with the main themes and arguments and ideas of the authors of the papers contributed to this volume. (shrink)

Fifty years ago, Herbert Simon complained that the available models of rational choice were not feasible decision procedures for agents like us. These models involved variants on the theme of maximizing expected utility: the rational action for an agent is the one that is most likely to bring about outcomes that the agent prefers. Simon ’s complaints about these models included the now-familiar notions that human beings do not manage probabilities well, that we have at best radically incomplete utility functions, (...) and that we lack the cognitive resources to calculate the expected utilities of even a few alternatives.

I consider an old problem for preference satisfaction theories of wellbeing: that they have trouble answering questions about interpersonal comparisons, such as whether I am better off than you are, or whether a particular policy benefits me more than it benefits you. I argue that a similar problem arises for intrapersonal comparisons in cases of transformative experience. I survey possible solutions to the problem, and point out some subtle disanalogies between the problem involving interpersonal comparisons and the problem involving transformative (...) experience.

This paper proposes a way to understand transformative choices, choices that change ‘who you are.’ First, it distinguishes two broad models of transformative choice: 1) ‘event-based’ transformative choices in which some event—perhaps an experience—downstream from a choice transforms you, and 2) ‘choice-based’ transformative choices in which the choice itself—and not something downstream from the choice—transforms you. Transformative choices are of interest primarily because they purport to pose a challenge to standard approaches to rational choice. An examination of the event-based transformative (...) choices of L. A. Paul and Edna Ullman-Margalit, however, suggests that event-based transformative choices don’t raise any difficulties for standard approaches to rational choice. An account of choice-based transformative choices—and what it is to be transformed—is then proposed. Transformative choices so understood not only capture paradigmatic cases of transformative choice but also point the way to a different way of thinking about rational choice and agency. (shrink)

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)

Comparative overall similarity lies at the basis of a lot of recent metaphysics and epistemology. It is a poor foundation. Overall similarity is supposed to be an aggregate of similarities and differences in various respects. But there is no good way of combining them all.

The topic of self-interest raises large and intractable philosophical questions–most obviously, the question “In what does self-interest consist?” The concept, as opposed to the content of self-interest, however, seems clear enough. Self-interest is interest in one's own good. To act self-interestedly is to act on the motive of advancing one's own good. Whether what one does actually is in one's self-interest depends on whether it actually does advance, or at least, minimize the decline of, one's own good. Though it may (...) be difficult to tell whether a person is motivated by self-interest in a particular instance, and difficult also to determine whether a given act or decision really is in one's self-interest, the meaning of the claims in question seems unproblematic. My main concern in this essay is to make a point about the content of self-interest. Specifically I shall put forward the view that meaningfulness, in a sense I shall elaborate, is an important element of a good life. It follows, then, that it is part of an enlightened self-interest that one wants to secure meaning in one's life, or, at any rate, to allow and promote meaningful activity within it. Accepting this substantial conception of self-interest, however, carries with it a curious consequence: the concept of self-interest which formerly seemed so clear begins to grow fuzzy. Fortunately, it comes to seem less important as well. In Reasons and Persons, Derek Parfit distinguishes three sorts of theories about self-interest–hedonistic theories, preference theories, and what he calls “objective-list theories." Hedonistic theories hold that one's good is a matter of the felt quality of one's experiences. (shrink)

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.

abstract In this paper I develop a characterization of disability according to which disability is in no way a sub-optimal feature. I argue, however, that this conception of disability is compatible with the idea that having a disability is, at least in a restricted sense, a harm. I then go on to argue that construing disability in this way avoids many of the common objections levelled at accounts which claim that disability is not a negative feature.

This paper is the introduction to the volume. It gives an argumentative view of the philosophical landscape concerning incommensurability and incomparability. It argues that incomparability, not incommensurability, is the important phenomenon on which philosophers should be focusing and that the arguments for the existence of incomparability are so far not compelling.

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’.

The article explicates a notion of prudence according to which an agent acts prudently if he acts so as to satisfy not only his present preferences, but his past and future preferences as well. A simplified decision-theoretic framework is developed within which three analyses of prudence are presented and compared. That analysis is defended which can best handle cases in which an agent's present act will affect his future preferences.

It is my view that one essential difference between persons and other creatures is to be found in the structure of a person's will. Besides wanting and choosing and being moved to do this or that, men may also want to have certain desires and motives. They are capable of wanting to be different, in their preferences and purposes, from what they are. Many animals appear to have the capacity for what I shall call "first-order desires" or "desires of the (...) first order," which are simply desires to do or not to do one thing or another. No animal other than man, however, appears to have the capacity for reflective self-evaluation that is manifested in the formation of second-order desires. (shrink)

This paper explores the problem of comparing the strengths of different individual's attitudes, and especially their evaluative attitudes, by looking at how measures of these quantities are obtained. I argue that comparisons of both strengths of belief and relative strengths of preference and desire are justified by the causal role they play in the production of action.

The incomparability of alternatives is thought to pose a problem for justified choice, particularly for proponents of comparativism better than,worse than,equally good,roughly equalon a par. namely, rejection of the transitivity of the relation In this paper, I argue that proponents of comparativism need not incur this cost. I defend the possibility of justified choice between incomparable alternatives on grounds that comparativists can accept. The possibility of incomparability has been met with resistance, in part because of the intuitive appeal of comparativism. (...) By defending the possibility of justified choice between incomparable alternatives on grounds that comparativists can accept, this paper supports further inquiry into the subject of incomparability.

I consider the implications of incommensurability for the assumption, in rational choice theory, that a rational agent’s preferences are complete. I argue that, contrary to appearances, the completeness assumption and the existence of incommensurability are compatible. Indeed, reflection on incommensurability suggests that one’s preferences should be complete over even the incommensurable alternatives one faces.

Several philosophers have argued that interpersonal comparisons of utility are problematic or even impossible, and that this poses a problem for the thesis that pleasure is a legitimate, measurable quantity. This, in turn, is thought to pose a problem of some kind for a variety of normative ethical and axiological theories. Perhaps it is supposed to show that utilitarianism or hedonism is false, or is supposed to show that there is no genuine hedonic calculus, or that any view that presupposes (...) that pleasure and pain are morally relevant is false or untenable. Its proponents begin by noticing that interpersonal comparisons of pleasure and pain are impossible in some relevant sense. This impossibility has been exploited by different philosophers for different purposes. It is clear, however, that a great many ethical theories rely in some way on the thesis that pleasure is measurable, and that its incoherence therefore threatens a great many theories in ethics. The purpose of this paper is to survey several of the most interesting versions of this argument; then to explain several attempts to respond to the problem, and to explain why each attempt fails; then to present, explain, and defend the correct solution to the problem.

A prominent contemporary anti-skeptical strategy, most famously articulated by Keith DeRose, aims to cage the skeptic′s doubts by contextualizing subjunctive conditional accounts of knowledge through a conversational rule of sensitivity. This strategy, I argue, courts charges of circularity by selectively invoking heavy counterfactual machinery. The reason: such invocation threatens to utilize a metric for modal comparison that is implicitly informed by judgments of epistemic sameness. This gives us reason to fear that said modal metric is selectively cherry-picked in advance to (...) support the very anti-skeptical conclusion for which the contextualist longs. (shrink)

We use “I’ll be glad I did it” reasoning all the time. For example, last night I was trying to decide whether to work on this paper or go out to a movie. I realized that if I worked on the paper, then today I would be glad I did it. Whereas, if I went out to the movie, today I would regret it. This enabled me to see that I should work on the paper rather than going out to (...) a movie. This looks like excellent reasoning: Paper argument: 1. If I work on my paper, I’ll be glad I did it. 2. Therefore, I should work on my paper. When we’re having trouble making a big life decision, we often try to picture what will happen each way we might choose, and imagine how we’ll feel in that outcome. When choosing between two jobs, we might use this reasoning. Suppose you are choosing between two jobs and you know quite a lot about what the two jobs will be like. In one, you will make a lot of money but have to work eighty-hour weeks and see little of your family. In the other, you will make considerably less money—though enough to support yourself and your family. You’ll have much more time for your family. The money is attractive. But overall, you realize you’ll be glad to have the time with your family if you take the second job—you’ll be glad you made that choice. It seems this is a good way of realizing that you should take the second job. (shrink)

Continues the discussion of theoretical and practical perfection by examining the considerations that give some beliefs and intentions more quality and therefore value than others. It argues that Aristotelian considerations about rationality as essential to humans require measures of quality to be formal, considering only formal properties of beliefs and ends rather than their substantive content. There are two such measures: the extent of a belief's or end's content in space, time, and objects involved, and the degree to which different (...) beliefs and ends are organized in a hierarchical structure. Together, these measures value explanatorily organized knowledge, a unified life, and complex, difficult activities such as games. (shrink)
