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)

This essay discusses a foundation of the connection argued to exist between law and practical reason that has proved to be highly influential and debated in contemporary legal philosophy – Alexy’s. After reconstructing Alexy’s conception of practical reason as well as its foundation, I criticise the weak transcendental-pragmatic argument Alexy uses to ground the authority of practical reason. This argument, I argue, can only show why occasionally, as opposed to necessarily, we ought to follow the guidance of practical reason, and (...) consequently makes the authority of practical reason ultimately dependent on an individual decision. By building on this criticism, in the second part of the essay I introduce and discuss an alternative argument that, by appealing to the idea of constitutive necessity, can provide a non-contingent basis for the validity of practical reason.

According to a subjectivist theory, normative reasons are grounded in facts about our desires. According to an instrumentalist theory, reasons are grounded also in facts about the relevant means to desired objects. These are distinct theories. The widespread tendency to conflate the normativity of subjective and instrumentalist precepts obscures two facts. First, instrumentalist precepts incorporate a subjective element with an objective one. Second, combining these elements into a single theory of normative reasons requires explaining how and why they are to (...) be combined. I argue that the most plausible justification for combining the two elements—which appeals to a theory of well‐being—exposes the inadequacy of the instrumentalist theory: The grounds required to justify the instrumentalist combination are also grounds for the normativity of prudential precepts and with them practical reasons that may have no internal connection to an agent's conative, motivational states.

Moore's paradox is a paradox in which certain kinds of belief or assertion, such as a belief that ?it is raining and I do not believe that it is raining?, are irrational despite involving no obvious contradiction in what is believed. But is there a parallel paradox involving other kinds of attitude, in particular desire? I argue that certain kinds of desire would be irrational to have for similar, distinctive reasons that having Moorean beliefs would be irrational to have. Hence, (...) I argue that such desires, a desire that ?one have a particular desire that was frustrated? or a desire that ?some state of affairs obtain about which one was indifferent?, are a parallel Moorean paradox of desire. I further argue that this analogous paradox has implications for practical reasoning, in particular by presenting a problem for instrumentalism about the objects of desire. (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.

What is the relation between desire and action? According to a traditional, widespread and influential view I call ‘The Motivational Necessity of Desire’ (MN), having a desire that p entails being disposed to act in ways that you believe will bring about p. But what about desires like a desire that the committee chooses you without your needing to do anything, or a desire that your child passes her exams on her own? Such ‘self-passive’ desires are often given as a (...) counter-example to MN. If MN is true then self-passive desires seem absurd: if someone has a self-passive desire she will be disposed to act, thereby preventing her from getting what she desires. But it seems that we can reasonably, and often do, have such desires. However, I argue that self-passive desires are not, in fact, counter-examples to MN: close consideration of the content of these desires, the contexts in which we ascribe them, and what is claimed by MN show that they are not a problem for that view. I also argue that strengthened versions of the examples are unsuccessful, and I offer a diagnosis of why these kinds of case are commonly thought to raise a challenge to MN. (shrink)

Is it permissible to kill an innocent person against her will in order to prevent several other innocent persons from being killed against their will? The answer to which this essay comes after extensive discussion is – under certain conditions and limitations – affirmative. On the way to this answer, the book offers a comprehensive in-depth discussion of so-called deontic restrictions – that is, the idea of an action’s being prohibited in circumstances in which performing it once would be the (...) only way to prevent its being performed multiple times. The book’s leading question is whether there is a plausible rationale for deontic restrictions. To this effect, a taxonomy and critical discussions of the most important approaches to justify deontic restrictions are provided – where many of these approaches undergo a deeper examination for the first time ever. In addition, the book clarifies some adjoining questions, such as why deontic restrictions are often perceived as being problematic or how the concept of agent-relativity should best be understood and formalized. Put into broader perspective, the conclusions offered should have a bearing on a number of debates in normative ethics, not least on the debate between deontologists and consequentialist. (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.

If moral status depends on the capacity for consciousness, what kind of consciousness matters exactly? Two popular answers are that any kind of consciousness matters (Broad Sentientism), and that what matters is the capacity for pleasure and suffering (Narrow Sentientism). I argue that the broad answer is too broad, while the narrow answer is likely too narrow, as Chalmers has recently argued by appeal to ‘philosophical Vulcans’. I defend a middle position, Motivational Sentientism, on which what matters is motivating consciousness: (...) any kind of consciousness which presents its subject with reasons for action. (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)

This paper defends Humeanism: the view that an agent has a reason for an intentional action if and only if it fulfills, or is a means to fulfilling, a current desire of that agent. Thomas Nagel presents an example involving a short-lived desire for eating a persimmon tomorrow. He claims that, contrary to Humeanism, this example is a clear case of irrationality. Furthermore, the Humean cannot simply dismiss all current desires with future objects, because desires of this sort are crucial (...) to the Humean account of prudence. I respond that, correctly understood, Humeanism can simultaneously account for prudent conduct and other conduct motivated by present desires with future objects. (shrink)

This chapter surveys the debate between philosophers who claim that all practical rationality is procedural and philosophers who claim that some practical rationality is substantive.

Hedonism and the desire-satisfaction theory of welfare are typically seen as archrivals in the contest over identifying what makes one's life go best. It is surprising, then, that the most plausible form of hedonism just is the most plausible form of desire satisfactionism. How can a single theory of welfare be a version of both hedonism and desire satisfactionism? The answer lies in what pleasure is: pleasure is, in my view, the subjective satisfaction of desire. This thesis about pleasure is (...) clarified and defended only after we proceed through the dialectics that get us to the most plausible forms of hedonism and desire satisfactionism. (shrink)

In this review article I refer to some of the most relevant recent publications in the field of practical rationality, mainly drawing on two new anthologies by Wallace and Millgram that contain the principal arguments in the current debate, and on new books and articles by Bittner, Dancy, Nida-Rümelin and Raz. The purpose of the article is to offer an overview of the relevant positions in the current debate, to clarify the main arguments against the belief-desire model, and to situate (...) some of the problems - e.g. what counts as a reason - within the wider field of practical rationality as a whole - e.g. how to argue about practical reasoning from the point of view of our self-understanding as autonomous agents.

This paper offers one formal reason why it may often be inappropriate to hold, of two conflicting desires, that the first must be weaker than, stronger than, or of the same strength as the second. The explanation of this fact does not rely on vagueness or epistemological problems in determining the strengths of desires. Nor does it make use of the problematic notion of incommensurability. Rather, the suggestion is that the motivational capacities of many desires might best be characterized by (...) two values, neither of which should be interpreted as strength. (shrink)

Desires matter. What are desires? Many believe that desire is a motivational state: desiring is being disposed to act. This conception aligns with the functionalist approach to desire and the standard account of desire's role in explaining action. According to a second influential approach, however, desire is first and foremost an evaluation: desiring is representing something as good. After all, we seem to desire things under the guise of the good. Which understanding of desire is more accurate? Is the guise (...) of the good even right to assume? Should we adopt an alternative picture that emphasizes desire's deontic nature? What do neuroscientific studies suggest? -/- Essays in the first section of the volume are devoted to these questions, and to the puzzle of desire's essence. In the second part of the volume, essays investigate some implications that the various conceptions of desire have on a number of fundamental issues. For example, why are inconsistent desires problematic? What is desire's role in practical deliberation? How do we know what we want? -/- This volume will contribute to the emergence of a fruitful debate on a neglected, albeit crucial, dimension of the mind. (shrink)

Modern theory of rationality has truly grown into a science of its own. Still, the general topic remained a genuinely philosophical one. This essay is concerned with giving a brief overview. Section 2 explains the fundamental scheme of all rationality assessments. With its help, a schematic order of the main questions concerning the theory of rationality can be given; the questions turn out to be quite unevenly addressed in the literature. Section 3 discusses the fundamental issue that the theory of (...) rationality seems to be both a normative and an empirical theory. Section 4, finally, shows how the unity of the theory of rationality can nevertheless be maintained. (shrink)

The problem of act individuation is a debate about the identity conditions of human acts. The fundamental question about act individuation is: how do we distinguish between actions? Three views of act individuation have dominated the literature. First, Donald Davidson and G.E.M. Anscombe have argued that a number of different descriptions refer to a single act. Second, Alvin Goldman and Jaegwon Kim have argued that each description designates a distinct act. Finally, Irving Thalberg and Judith Jarvis Thomson have averred that (...) some acts are sequences of causally related events, which include both a primitive bodily action and some of its effects. All of these accounts have assumed that a simple invariantist account of act individuation captures how ordinary people distinguish between acts. For my dissertation, I devised an experiment to test the action theorists' assumptions. My data show that people's intuitions seem to depend on the valence of the consequences of the action under consideration. So, an invariantist account is not possible. In light of the empirical results, I argue that if we seek a folk account of act individuation, then that account should be able to explain the variability that seems to be present in people's intuitions about different cases.

Intentional actions are those which are performed because the subject sees something to be said for performing them; the subject sees performing the action “in a positive light”. Intentional actions are therefore susceptible to a distinctive kind of explanation, which explains them as intentional; that is, which accounts for them in terms of their unique property, of being performed because the subject sees that there is something to be said for doing so. Practical reasoning is the process of figuring out (...) what there is reason to do; that is, what actions are best supported by the considerations available to the subject. To put it another way, practical reasoning is the process of figuring out which actions there is the most to be said for; so practical reasoning explains intentional action “properly”, i.e., in terms of its special properties. Many philosophers, loosely following the lead of David Hume, have argued for a close connection between desire and intentional action. If desires explain intentional actions properly, then they must do so through practical reasoning; that being the case, how do they do it? Another sizeable group of philosophers, the anti-Humeans, have argued that desires cannot explain intentional actions properly; they claim that desires are not the right sorts of things to appear in the premises of arguments, do not count in favour of any action, do not constitute evaluations of any action, and are in any case too fickle and lawless to take part in distinctively normative forms of explanation. The central question in this thesis is, what is the role of desire in practical reasoning? I put forward a characterisation of desire which explains how some desires can explain intentional actions properly, and leaves the question open whether all intentional actions are properly explained by desires.

The so-called ‘central problem’ of internalism has been formulated like this: one cannot concurrently maintain the following three philosophical positions without inconsistency: internalism about practical reason, moral rationalism, and moral absolutism. Since internalism about practical reason is the most controversial of these, the suggestion is that it is the one that is best abandoned. In this paper, I point towards a response to this problem by sketching a deontic logic of internal reasons that deflates moral normativity to the normativity of (...) instrumental rationality, and provides support for the assertion that one can hold fast simultaneously to internalism and at least many of the intuitive commitments of liberal moral thinking. Crucial to the proposal is an account of the enkratic principle – I ought to attempt to realise what I ultimately desire – as the source of obligations we owe to ourselves. I attempt to show how from this, in conjunction with some plausible assumptions, obligations to others might be derived. (shrink)

Theories of welfare answer the ancient question, What makes a person's life go well? Prominent among these are desire-satisfaction or preferentist theories, according to which welfare has to do ultimately with desire. This dissertation aims to criticize some recent popular arguments against standard desire-satisfaction theories of welfare, to develop and defend a novel version of the desire-satisfaction theory capable of answering the better objections, to defend the thesis that pleasure is reducible to desire, and to demonstrate an interesting link between (...) preferentism and hedonism. The second chapter defends a simple "actualist" desire-satisfaction theory against the contention that such a theory cannot accommodate the fact that we can desire things that are bad for us. All the allegedly defective desires, I attempt to show, are either not genuinely defective or else can be accounted for by the theory. The third chapter criticizes the popular line that standard desire-based theories of welfare are incompatible with the conceptual possibility of self-sacrifice. I show that even the simplest imaginable, completely unrestricted desire theory is compatible with self-sacrifice, so long as it is formulated properly. The fourth chapter presents and defends a theory according to which welfare consists in the perceived satisfaction, or "subjective satisfaction," of desire. I argue that this theory is best suited to deflect the many lines of argument threatening the preferentist program. The fifth chapter defends the view that desire is what unifies the heterogeneous lot of experiences that all count as sensory pleasures. I develop and defend a desire theory of sensory pleasure. The sixth chapter argues that the most plausible form of preferentism is equivalent to the most plausible form of its main rival, hedonism. This is because what the best preferentism says---that welfare consists in subjective desire satisfaction---is the same as what the best hedonism says---that welfare consists in propositional pleasure---given a reduction of pleasure to desire along the lines of that defended above.
