This dissertation is on infinite regress arguments in philosophy. Its main goals are to explain what such arguments from many distinct philosophical debates have in common, and to provide guidelines for using and evaluating them. Two theories are reviewed: the Paradox Theory and the Failure Theory. According to the Paradox Theory, infinite regress arguments can be used to refute an existentially or universally quantified statement (e.g. to refute the statement that at least one discussion is settled, or the statement that (...) discussions are settled only if there is an agreed-upon criterion to settle them). According to the Failure Theory, infinite regress arguments can be used to demonstrate that a certain solution fails to solve an existentially or universally quantified problem (e.g. to demonstrate that a certain solution fails to settle all discussions, or that it fails to settle even one discussion). In the literature, the Paradox Theory is fairly well-developed, and this dissertation provides the Failure Theory with the same tools. (shrink)

Theoretical and practical deliberation are voluntary activities, and like all voluntary activities, they are performed for reasons. To hold that all voluntary activities are performed for reasons in virtue of their relations to past, present, or even merely possible acts of deliberation thus leads to infinite regresses and related problems. As a consequence, there must be processes that are nondeliberative and nonvoluntary but that nonetheless allow us to think and act for reasons, and these processes must be the ones that (...) generate the voluntary activities making up ordinary deliberation. These nondeliberative, nonvoluntary processes by means of which we are able to deliberate for reasons are the fundamental processes by means of which we can think or do anything for a reason: once it has been seen that they must exist, it can be recognized that they are ubiquitous. As a result, the usefulness of deliberation to rational belief and action is intermittent, contingent, and modest. Deliberation is a tremendously valuable tool for increasing human capacities to think and act for good reasons in challenging contexts, but in the end it is merely a tool, wielded by people through the same nondeliberative, nonvoluntary capacities to think and act for reasons that they are enhancing the effectiveness of by deliberating.

Consider the claim that openmindedness is an epistemic virtue, the claim that true belief is epistemically valuable, and the claim that one epistemically ought to cleave to one’s evidence. These are examples of what I’ll call “ epistemic discourse.” In this paper I’ll propose and defend a view called “convention-relativism about epistemic discourse.” In particular, I’ll argue that convention-relativismis superior to its main rival, expressivism about epistemic discourse. Expressivism and conventionalism both jibe with anti-realism about epistemic normativity, which is motivated (...) by appeal to philosophical naturalism. Convention-relativism says that epistemic discourse describes how things stands relative to a conventional set of “ epistemic ” values; such discourse is akin to normative discourse relative to the conventional rules of a club. I defend conventionalism by appeal to a “reverse open question argument,” which says, pace expressivism, that epistemic discourse leaves the relevant normative questions open. (shrink)

This article is a critique of Gal Yehezkel’s attempt to refute subjectivism about normative practical reasons, a school of thought inspired by Hume. Yehezkel believes reason, far from being, as Hume puts it, “the slave of the passions,” has the normative authority to be a critic of basic desires and argues that subjectivism lacks the theoretical resources both to acknowledge this alleged truth and to analyze the distinction between wanting an outcome and intending to pursue it. I contend his refutation (...) fails, largely because it operates with a strikingly attenuated view of the subjectivist theory. (shrink)

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.

In this paper, I propose a critique of the naturalist version of the Desire-Based Reasons Model. I first set the scene by spelling out the connection between naturalism and the Model. After this, I introduce Christine Korsgaard’s circularity argument against what she calls the instrumental principle. Since Korsgaard’s targets, officially, were non-naturalist advocates of the principle, I show why and how the circularity charge can be extended to cover the naturalist Model. Once this is done, I go on to investigate (...) in some detail the different ways of responding to the circularity challenge. I argue that none of these responses succeed, at least not without serious costs to their advocates. I then end the paper with a brief summary and some concluding remarks. (shrink)

This paper examines two arguments against the possibility of moral responsibility—the first directly from the work of Galen Strawson and the next inspired by Strawson’s argument. Both of these arguments are found wanting, and their shortcomings are used as a springboard to sketch a positive libertarian view of moral responsibility and defend that view against preliminary objections.

The question ‘Why care about being an agent?’ asks for reasons to be something that appears to be non-optional. But perhaps it is closer to the question ‘Why be moral?’; or so I shall argue. Here the constitutivist answer—that we cannot help but have this aim—seems to be the best answer available. I suggest that, regardless of whether constitutivism is true, it is an incomplete answer. I argue that we should instead answer the question by looking at our evaluative commitments (...) to the exercise of our other capacities for which being a full-blown agent is a necessary condition. Thus, the only kind of reason available is hypothetical rather than categorical. The status of this reason may seem to undermine the importance of this answer. I show, however, that it both achieves much of what we want when we cite categorical reasons and highlights why agency is valuable. (shrink)

Practical deliberation consists in thinking about what to do. Such deliberation is deemed rational when it conforms to certain normative requirements. What is often ignored is the role that an agent's context can play in so-called ‘failures’ of rationality. In this paper, I use recent cognitive science research investigating the effects of resource-scarcity on decision-making and cognitive function to argue that context plays an important role in determining which norms should structure an agent's deliberation. This evidence undermines the view that (...) the norms of ‘ideal’ rationality are necessary and universal requirements on deliberation. They are a solution to the problems faced by cognitively limited agents in a context of moderate scarcity. In a context of severe scarcity, the problems faced by cognitively limited agents are different and require deliberation structured by different norms. Agents reason rationally when they use the norms best suited to their context and cognitive capacities. (shrink)

Instrumentalism is the view that all requirements of practical reason can be derived from the instrumental principle, that is, from the claim that one ought to take the suitable means to one's ends. Rationalists, by contrast, hold that there are requirements of practical reason that concern the normative acceptability of ends. To the extent that rationalists put forward these requirements in addition to the instrumental principle, rationalism might seem to go beyond instrumentalism in its normative commitments. This is why it (...) is sometimes thought that rationalism is stronger than instrumentalism in a way that entails that instrumentalism is the default view, while rationalists carry the burden of proof. In this paper, I explore and discuss different ways of spelling out this idea. I argue that rationalism is not stronger than instrumentalism in a way that has implications for matters of justification and differences in prima facie defensibility of the two sorts of views.

Often our reason for doing something is an "instrumental reason": that doing that is a means to doing something else that we have reason to do. What principles govern this "instrumental transmission" of reasons from ends to means? Negatively, I argue against principles often invoked in the literature, which focus on necessary or sufficient means. Positively, I propose a principle, "General Transmission," which answers to two intuitive desiderata: that reason transmits to means that are "probabilizing" and "nonsuperfluous" with respect to (...) the relevant end. I then apply General Transmission to the debate over "detachment": whether "wide-scope" reason for a material conditional or disjunction implies "narrow-scope" reason for the consequent or disjuncts.

We often treat our basic, unmotivated desires as reason-giving: you’re thirsty and take yourself to have a reason to walk to the drinking fountain; you care intrinsically about your young daughter and take yourself to have a reason to feed and clothe her. We think these desires generate normative practical reasons. But are there basic desires that don’t? It might seem so, for we sometimes find ourselves impelled to do some very strange, and some very awful, things. For example, would (...) a loving mother with a violent impulse thereby come to have a reason to harm her beloved child? Let’s grant, for the sake of argument, that there are basic desires, such as the mother’s, that fail to generate reasons. Can a subjectivist, a theorist in the Humean tradition, accept this thesis? Against the historical grain, I argue yes. I frame my discussion in terms of solving a puzzle in Harry Frankfurt’s subjectivist theory of rational agency and appeal to the concept of a personal ideal to reveal how a subjectivist, a follower of Hume, can countenance the existence of “rationally impotent basic desires.”.

This book on infinite regress arguments provides (i) an up-to-date overview of the literature on the topic, (ii) ready-to-use insights for all domains of philosophy, and (iii) two case studies to illustrate these insights in some detail. Infinite regress arguments play an important role in all domains of philosophy. There are infinite regresses of reasons, obligations, rules, and disputes, and all are supposed to have their own moral. Yet most of them are involved in controversy. Hence the question is: what (...) exactly is an infinite regress argument, and when is such an argument a good one? (shrink)

According to an influential view of practical reason and rational agency, a person acts for a reason only if she recognizes some consideration to be a reason, where this recognition motivates her to act. I call this requirement the guidance condition on acting for a reason. Despite its intuitive appeal, the guidance condition appears to generate a vicious regress. At least one proponent of the guidance condition, Christine M. Korsgaard, is sensitive to this regress worry, and her appeal in recent (...) work to the constitutive principles of action can be seen, in part, as a response to it. I argue, however, that if we are to appeal to the constitutive principles of action to resolve the regress, then we must determine whether acting on such principles is also subject to the guidance condition. This raises a dilemma. If following these principles is subject to the guidance condition, then the regress remains unresolved. But if not, then the rationale for applying it to acting for a reason vanishes as well. I conclude that we should embrace an account of acting for a reason that rejects the guidance condition.

This book contains a selection of the papers presented at the Logic, Reasoning and Rationality 2010 conference in Ghent. The conference aimed at stimulating the use of formal frameworks to explicate concrete cases of human reasoning, and conversely, to challenge scholars in formal studies by presenting them with interesting new cases of actual reasoning. According to the members of the Wiener Kreis, there was a strong connection between logic, reasoning, and rationality and that human reasoning is rational in so far (...) as it is based on logic. Later, this belief came under attack and logic was deemed inadequate to explicate actual cases of human reasoning. Today, there is a growing interest in reconnecting logic, reasoning and rationality. A central motor for this change was the development of non-classical logics and non-classical formal frameworks. The book contains contributions in various non-classical formal frameworks, case studies that enhance our apprehension of concrete reasoning patterns, and studies of the philosophical implications for our understanding of the notions of rationality.

Some philosophers have tried to establish a connection between the normativity of instrumental rationality and the paradox presented by Lewis Carroll in his 1895 paper “What the Tortoise Said to Achilles.” I here examine and argue against accounts of this connection presented by Peter Railton and James Dreier before presenting my own account and discussing its implications for instrumentalism (the view that all there is to practical rationality is instrumental rationality). In my view, the potential for a Carroll-style regress just (...) shows us that since instrumental rationality involves a higher-order commitment to combine our willing an end with our taking the necessary means, it therefore cannot, on pain of regress, itself be added as a conjunct to one of the elements to be combined. This view does not support instrumentalism. (shrink)

Amanda works in a library, and a patron asks for her help in learning about duty-to- rescue laws in China. She throws herself into the task, spending hours on retrieving documents from governmental and non-governmental sources, getting electronic translations, looking for literature on Scandinavian duty-to-rescue laws that mention Chinese laws for comparison, and so on. Why? She likes to gain this sort of general knowledge of the world; perhaps the reason she works so hard is that she is learning fascinating (...) facts in doing so. She is also a proud librarian; perhaps the reason she works so hard is that a patron needs her assistance. She is a library employee; perhaps her reason for working so hard is that this sort of effort is noted by her employer and gives her career a boost, or perhaps it is just that doing this sort of work is the condition of her continued employment. Perhaps the reason is that the patron is charming. (shrink)
