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)

For many epistemologists, and for many philosophers more broadly, it is axiomatic that rationality requires you to take the doxastic attitudes that your evidence supports. Yet there is also another current in our talk about rationality. On this usage, rationality is a matter of the right kind of coherence between one's mental attitudes. Surprisingly little work in epistemology is explicitly devoted to answering the question of how these two currents of talk are related. But many implicitly assume that evidence -responsiveness (...) guarantees coherence, so that the rational impermissibility of incoherence will just fall out of the putative requirement to take the attitudes that one's evidence supports, and so that coherence requirements do not need to be theorized in their own right, apart from evidential reasons. In this paper, I argue that this is a mistake, since coherence and evidence -responsiveness can in fact come into conflict. More specifically, I argue that in cases of misleading higher-order evidence, there can be a conflict between believing what one's evidence supports and satisfying a requirement that I call “inter-level coherence ”. This illustrates why coherence requirements and evidential reasons must be separated and theorized separately. (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.

My dissertation is a systematic defense of the claim that what it is to be rational is to correctly respond to the reasons you possess. The dissertation is split into two parts, each consisting of three chapters. In Part I--Coherence, Possession, and Correctly Responding--I argue that my view has important advantages over popular views in metaethics that tie rationality to coherence (ch. 2), defend a novel view of what it is to possess a reason (ch. 3), and defend a novel (...) view about what it is to act and hold attitudes for normative reasons (ch. 4). In Part II--Foundationalism, Deception, and The Importance of Being Rational--I argue that foundationalists about epistemic rationality should think that the foundational beliefs are held for sufficient reasons (ch. 5), argue that my view solves the New Evil Demon problem for externalism (and solves a related and underapprieciated problem) (ch. 6), and argue that my view can vindicate the thought that we ought to be rational (ch. 7).

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). (shrink)

What we value, like, endorse, want, and prefer changes over the course of our lives. Richard Pettigrew presents a theory of rational decision making for agents who recognise that their values will change over time and whose decisions will affect those future times.

Should you care less about your distant future? What about events in your life that have already happened? How should the passage of time affect your planning and assessment of your life? Most of us think it is irrational to ignore the future but harmless to dismiss the past. But this book argues that rationality requires temporal neutrality.

Kiesewetter defends the normativity of rationality by presenting a new solution to the problems that arise from the common assumption that we ought to be rational. He provides a defence of a reason-response conception of rationality, an evidence-relative account of reason, and an explanation of structural irrationality in relation to these accounts.

Recent work on rationality has been increasingly attentive to “coherence requirements”, with heated debates about both the content of such requirements and their normative status (e.g., whether there is necessarily reason to comply with them). Yet there is little to no work on the metanormative status of coherence requirements. Metaphysically: what is it for two or more mental states to be jointly incoherent, such that they are banned by a coherence requirement? In virtue of what are some putative requirements genuine (...) and others not? Epistemologically: how are we to know which of the requirements are genuine and which aren’t? This paper tries to offer an account that answers these questions. On my account, the incoherence of a set of attitudinal mental states is a matter of its being (partially) constitutive of the mental states in question that, for any agent that holds these attitudes jointly, the agent is disposed, when conditions of full transparency are met, to give up at least one of the attitudes.

Going about our daily lives in an orderly manner requires us, once we are aware of them, to dismiss many metaphysical possibilities. We take it for granted that we are not brains in vats, or living in the Matrix, or in an extended dream. Call these things that we take for granted “anti-skeptical assumptions”. What should a reflective agent who believes these things think of these beliefs? For various reasons, it can seem that we do not have evidence for such (...) anti-skeptical assumptions. Are anti-skeptical assumptions, then, beliefs that one may rationally hold without evidence for them – indeed, even in the face of a positive judgment that one lacks evidence for them? I survey and criticize some prominent answers to this question, and then offer a positive view that blends externalism about evidence with a mild, qualified kind of pragmatism. The view I offer aims to do justice to the sense that anti-skeptical assumptions are evidentially groundless while also maintaining that one cannot rationally believe something that one judges oneself to lack sufficient evidence for.

I argue that we can understand the de se by employing the subjective mode of presentation or, if one’s ontology permits it, by defending an abundant ontology of perspectival personal properties or facts. I do this in the context of a discussion of Cappelen and Dever’s recent criticisms of the de se. Then, I discuss the distinctive role of the first personal perspective in discussions about empathy, rational deference, and self-understanding, and develop a way to frame the problem of lacking (...) prospective access to your future self as a problem with your capacity to imaginatively empathize with your future selves.

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.

Decision theory aims at a general account of rationality covering humans but to begin makes idealizations about decision problems and agents' resources and circumstances. It treats inerrant agents with unlimited cognitive power facing tractable decision problems. This book systematically rolls back idealizations and without loss of precision treats errant agents with limited cognitive abilities facing decision problems without a stable top option. It recommends choices that maximize utility using quantizations of beliefs and desires in cases where probabilities and utilities are (...) indeterminate and using higher-order utility analysis in cases of limited access to probabilities and utilities. For agents burdened with mistakes, it advocates reasonable attempts to correct unacceptable mistakes before deciding. In decision problems without a stable top option, a topic of game theory, it proposes maximizing self-conditional utility among self-supporting options. In games of strategy, the new principles lead to solutions that are Pareto optimal among equilibria composed of jointly self-supporting strategies. Offering an account of bounded rationality, the bookmakes large strides toward realism in decision theory. (shrink)

Normal agents in the actual world are limited: they cannot think about all the options that are available to them—or even about all options that are available to them according to their evidence. Moreover, agents cannot choose an option unless they have thought about that option. Such agents can be irrational in two ways: either by making their choice too quickly, without canvassing enough options, or by wasting time canvassing ever more options when they have already thought of enough options. (...) This chapter proposes an account of this kind of rationality for limited agents. To be rational, such agents need a kind of background sensitivity to whether or not continuing to search for more options has greater expected value than deciding right away. According to this proposal, it is the unavoidable predicament of choice that all rational decision-making depends on the unconscious operation of mental dispositions. (shrink)

In her very interesting ‘First-personal modes of presentation and the problem of empathy’, L. A. Paul argues that the phenomenon of empathy gives us reason to care about the first person point of view: that as theorists we can only understand, and as humans only evince, empathy by appealing to that point of view. We are skeptics about the importance of the first person point of view, although not about empathy. The goal of this paper is to see if we (...) can account for empathy without the ideology of the first person. We conclude that we can. (shrink)

In her ground-breaking and highly influential book Transformative Experience, L.A. Paul makes two claims: (1) one cannot evaluate and compare certain experiential outcomes (e.g. being a parent and being a non-parent) unless one can grasp what these outcomes are like; and (2) one can evaluate and compare certain intuitively horrible outcomes (e.g. being eaten alive by sharks) as bad and worse than certain other outcomes even if one cannot grasp what these intuitively horrible outcomes are like. We argue that the (...) conjunction of these two claims leads to an implausible discontinuity in the evaluability of outcomes. One implication of positing such a discontinuity is that evaluative comparisons of outcomes will not be proportionally sensitive to variation in the underlying features of these outcomes. This puts pressure on Paul to abandon either (1) or (2). But (1) is central to her view and (2) is very hard to deny. We call this the Shark Problem. (shrink)

Our collective enthusiasm for empathy reflects a sense that it is deeply valuable. I show that empathy bears a complex and surprisingly problematic relation to another social epistemic phenomenon that we have reason to value, namely testimonial trust. My discussion focuses on empathy with and trust in people who are members of one or more oppressed groups. Empathy for oppressed people can be a powerful tool for engendering a certain form of testimonial trust, because there is a tight connection between (...) empathy and a approval of another's outlook. I then argue that the qualities of empathy that make it such a powerful tool for bridging differences and building trust also have a problematic upshot: they make it the case that reliance on empathy will sometimes have a distorting effect upon the ways we extend testimonial trust.
