In the tradition stemming from Aristotle through Aquinas, rational decision making is seen as a complex structure of distinct phases in which reasoning and will are interconnected. Intention, deliberation, and decision are regarded as the fundamental steps of the decision-making process, in which an end is chosen, the means are specified, and a decision to act is made. Based on this Aristotelian theoretical background, we show how the decision-making process can be modeled as a net (...) of several patterns of reasoning, involving the classification of an action or state of affairs, its evaluation, the deliberation about the means to carry it out, and the decision. It is shown how argumentation theory can contribute to our understanding of the mechanisms involved by formalizing the steps of reasoning using argumentation schemes, and setting out the value-based criteria underlying the evaluation of an action. Representing each phase of the decision-making process as a separate scheme allows one to identify implicit premises and bring the roots of ethical dilemma to light along with the means to resolve them. In particular, we will show the role of framing and classification in triggering value-based reasoning, and how argumentation theory can be used to represent and uproot the grounds of possible manipulations.

Practical reasoning aims at deciding what actions to perform in light of the goals a rational agent possesses. This has been a topic of interest in both philosophy and artificial intelligence, but these two disciplines have produced very different models of practical reasoning. The purpose of this paper is to examine each model in light of the other and produce a unified model adequate for the purposes of both disciplines and superior to the standard models employed by either.The (...) philosophical (decision-theoretic) model directs activity by evaluating acts one at a time in terms of their expected utilities. It is argued that, except in certain special cases, this constitutes an inadequate theory of practical reasoning leading to intuitively incorrect action prescriptions. Acts must be viewed as parts of plans, and plans evaluated as coherent units rather than piecemenal in terms of the acts comprising them. Rationality dictates choosing acts by first choosing the plans prescribing them. Plans, in turn, are compared by looking at their expected values. However, because plans can be embedded in one another, we cannot select plans just by maximizing expected values. Instead, we must employ a more complex criterion here named coextendability.

While most of healthcare research and practice fully endorses evidence-based healthcare, a minority view borrows popular themes from philosophy of science like underdetermination and value-ladenness to question the legitimacy of the evidence-based movement’s philosophical underpinnings. While the feminist origins go unacknowledged, those critics adopt a feminist reading of the “gap argument” to challenge the perceived objectivism of evidence-based practice. From there, the critics seem to despair over the “subjective elements” that values introduce to clinical reasoning, demonstrating that they do not (...) subscribe to feminist science studies’ normative program——where contextual values can enable good science and justified decisions. In this paper, I investigate why it is that the critics of evidence-based medicine adopt feminist science’s characterization of the problem but resist the productive solutions offered by those same theorists. I suggest that the common feminist empiricist appeal to idealized epistemic communities is impractical for those working within the current biomedical context and instead offer an alternate stream of feminist research into the empirical content of values (found in the work of Elizabeth Anderson and Sharyn Clough) as a more helpful recourse for facilitating the important task of legitimate and justified clinical decision-making. I use a case study on clinical decision-making to illustrate the fruitfulness of the latter feminist empiricist framework. -/- See response by Sharyn Clough: http://wp.me/p1Bfg0-1aN See reply by Maya Goldenberg: http://wp.me/p1Bfg0-1oY.

How should we decide which theory of practical reason is correct? One possibility is to link each conception of practical reason with a theory of value, and to assess the first in combination with the second. Recently some philosophers have taken a different approach. They have tried to link theories of practical reason with theories of action instead. I try to show that it can be illuminating to think of practical reason in terms of the success (...) conditions of action, but ultimately this is in addition to, rather than a substitute for, relating practical reason to value as well. I set out three different conceptions of action and corresponding success conditions, and explain how each is linked to a particular conception of practical reason and, in two cases, to a theory of value too. My goal is to describe these different accounts, rather than to defend any in particular, though I will suggest that some are more satisfactory than others. Key Words: action • commitment • intention • practical reason • value. (shrink)

The Possibility of Practical Reason explores the foundational questions of moral psychology: How can any of our behavior qualify as acting for a reason? How can any considerations qualify as reasons for us to act? David Velleman argues that both possibilities depend on there being a constitutive aim of action―something that makes for success in action as such. These twelve essays―five of which were not included in the previous edition, two of them previously unpublished―discuss topics such as freedom of (...) the will, shared intention, the relation between value and practical reasoning, the foundations of decision theory, and the motivational role of the imagination.

This paper argues that the types of intention can be modeled both as modal operators and via a multi-hyperintensional semantics. I delineate the semantic profiles of the types of intention, and provide a precise account of how the types of intention are unified in virtue of both their operations in a single, encompassing, epistemic space, and their role in practical reasoning. I endeavor to provide reasons adducing against the proposal that the types of intention are reducible to the mental (...) states of belief and desire, where the former state is codified by subjective probability measures and the latter is codified by a utility function. I argue, instead, that each of the types of intention -- i.e., intention-in-action, intention-as-explanation, and intention-for-the-future -- has as its aim the value of an outcome of the agent's action, as derived by her partial beliefs and assignments of utility, and as codified by the value of expected utility in evidential decision theory.

Presenting the most comprehensive and lucid account of the topic currently available, Robert Audi's "Practical Reasoning and Ethical Decision" is essential reading for anyone interested in the role of reason in ethics or the nature of human action. The first part of the book is a detailed critical overview of the influential theories of practical reasoning found in Aristotle, Hume and Kant, whilst the second part examines practical reasoning in the light of important topics in moral (...) psychology - weakness of will, self-deception, rationalization and others. In the third part, Audi describes the role of moral principles in practical reasoning and clarifies the way practical reasoning underlies ethical decisions. He formulates a comprehensive set of concrete ethical principles, explains how they apply to reasoning about what to do, and shows how practical reasoning guides moral conduct. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:For the Sake of Argument: Practical Reasoning, Character, and the Ethics of BeliefRobert MetcalfFor the Sake of Argument: Practical Reasoning, Character, and the Ethics of Belief. Eugene Garver. Chicago: University of Chicago Press, 2004. pp. 264. $55.00, hardcover; $22.50, paperback.Professor Garver's book, For the Sake of Argument: Practical Reasoning, Character, and the Ethics of Belief, is a provocative and illuminating study of practical reasoning, (...) and one that develops many of the ideas found in his magisterial study, Aristotle's Rhetoric: An Art of Character (Chicago: University of Chicago Press, 1994). The previous book concluded by arguing that Aristotle's Rhetoric is philosophically more interesting today than it was in Aristotle's time, in part because for us there is no polis to which the argumentative facility of rhetoric would be subordinate (1994, 233ff.). This idea is echoed in the present book when Garver writes: "The more we take disagreement to be a permanent part of the situation of practical reasoning, and not something soon to be overcome by appropriate theory or universal enlightenment, the more rhetorical facility becomes a central part [End Page 95] of practical reason" (2004, 175). It is, indeed, a fascinating feature of For the Sake of Argument that it defends the autonomy and integrity of practical reason through Aristotle's insights on the various connections between argument, persuasion, and ethos (153), and illustrates these through examples such as the South African Truth and Reconciliation Commission, the landmark Brown v. Board of Education, and subsequent Supreme Court decisions.The book is divided into eight chapters, and, as Garver explains, these represent four pairs of essays in which a more concrete or "applied" chapter is followed by a chapter that draws generalizations from the examples of the prior chapter. Among the themes most prominent in the book are the connection between reason and character, on which Garver writes, "Practical reason has its own integrity when who we are and how we think are intimately connected" (2); the compatibility, within practical reason, of truth and one's own interest; the "ampliative" nature of practical reason, such that the implications of one's beliefs can lead to discoveries unanticipated at the beginning; the connection between the ethos of a leader and the ethos of a community; and the underappreciated power of epideictic rhetoric "to affirm values and articulate new vocabularies" (178). In addressing such broad themes, Garver's attention to concrete examples, like Brown v. Board of Education, is thoroughly instructive. The Brown decision, he argues, is "an epideictic declaration that equality and antidiscrimination are fundamental American Constitutional values" (73). Brown clearly demonstrates the ampliative nature of practical reason in that the conclusion it reaches is stronger than the premises from which it begins (i.e., the Fourteenth Amendment); moreover, it generates what Garver calls an "ethical surplus" that allows for unanticipated implications that are stronger still, such as the later Court decision striking down antimiscegenation laws (71–73). This "increase" in strength in proceeding from premises to conclusion is "impossible under a purely deductive conception of rationality," Garver writes (73), yet it is well explained by his Aristotle-inspired account of practical reasoning.Surely some readers will recoil from Garver's more provocative claims, such as that "we decide... to be convinced and choose to find a line of reasoning compelling" (119), offered within a discussion of the responsibility we bear in ethical argumentation. However, the issue that is more problematic, to my mind, concerns Garver's treatment of Plato. This may seem odd, given that Plato only appears as a foil in the book—but the problem is that it is merely a caricature of Plato that Garver allows to act as [End Page 96] a foil. Garver argues against "the Platonic program which will save reason by removing it from human contamination" (3) and "the Platonic hope of replacing ethical reasoning by the certainties of science" (5). He sides with Aristotle's idea that we can aim at effectiveness and at rightness together (48, 200) over against the allegedly Platonic idea that we must choose between truth and our own interest, reason and emotion, and so forth, or else...

My dissertation focuses on problems that arise when a group makes decisions that are in reasonable ways connected to the beliefs and values of the group members. These situations are represented by models of decision-theoretic aggregation: Suppose a model of individual rationality in decision-making applies to each of a group of agents. Suppose this model also applies to the group as a whole, and that this group model is aggregated from the individual models. Two questions arise. First, what (...) sets of reasonable conditions can we consistently impose on the aggregation? Second, what can we learn from insights gained in such models, in particular for ethics and political philosophy? The dissertation has three parts, each using a different model of individual rationality. Each part contains essays addressing questions of either the first or the second kind with regard to its underlying model. Part I uses a social-choice-theoretic model, in which agents are only assumed to rank alternatives. Arrow's "Impossibility Theorem" shows that certain conditions that it would be natural to impose on all aggregation cannot be so imposed, on pain of contradiction. I discuss the impact of this result on the evaluation of majority rule and on democratic theory. I also discuss Sen's "Liberal Paradox", which addresses the possibility of incorporating rights into a social-choice theoretic model. Part II uses the von Neumann/Morgenstern theory of expected utility. A result under this model has been regarded as providing an argument for utilitarianism. I locate a place within utilitarianism where the theorem can do some work. To prepare the ground, I interpret the von Neumann/Morgenstern theory as part of a theory of deliberation. Thereby, this version of expected utility theory can be embedded into the philosophy of practical reasoning. The underlying model in Part III is Bayesian decision theory. Whereas the other two inquiries focus on the philosophical assessment of formal results, the third makes a formal contribution. One essay surveys the area, and a second explores a curious phenomenon that occurs in determining outcomes under one type of Bayesian aggregation. (shrink)

This book is a study of the role of intellect in human action as described by Thomas Aquinas. One of its primary aims is to compare the interpretation of Aristotle by Aquinas with the lines of interpretation offered in contemporary Aristotelian scholarship. The book seeks to clarify the problems involved in the appropriation of Aristotle's theory by a Christian theologian, including such topics as the practical syllogism and the problems of akrasia. Westberg argues that Aquinas was much closer to (...) Aristotle than is often recognized, and he puts forward important new interpretations of the relation of intellect and will in the stages of intention, deliberation, decision, and execution. In the concluding section of the book, he shows how this new interpretation yields fruitful insights on a range of theological topics, including sin, law, love, and the moral virtues. (shrink)

In this paper, I explore one line of argument for the Humean Theory of Reasons, the view that all normative reasons are based on desires. Then, I suggest a way to block that argument inspired by Aquinas’s discussions on choice, will, and indeterminacy of reason alone.

This thesis addresses two enduring issues in legal theory-- rationality and its association with rule of law values--by offering detailed models of two patterns of legal reasoning. One is reasoning by analogy. The other is the inference process that legal reasoners use when they defer epistemically to scientific experts in the course of reaching legal decisions. Discussions in both chapters reveal that the inference pattern known as "abduction" is a deeply important element of many legal inferences, including analogy and epistemic (...) deference to experts--something that has been largely unrecognized in legal theory. After presenting a detailed model of analogy, Chapter 1 argues that legal reasoning by analogy, like analogical argument in logic, mathematics, and the natural sciences, possesses a great deal of rational force when properly executed. Chapter 2 investigates the reasoning process by which non-expert legal reasoners defer epistemically to the judgments of scientists. It presents five main conclusions or explanations. Every practical syllogism actually consists of two distinct chains of inference, and what is usually considered in writings on practical reasoning to be the minor premise of a practical syllogism is actually the conclusion of a separate chain of argument. When a practical reasoner defers epistemically to a theoretical expert, this separate chain of argument has a special structure, which is modeled in Chapter 2. The non-expert legal reasoner must always make a prescriptive practical judgment about the standard of epistemic appraisal and level of epistemic confidence that the reasoner requires of scientific evidence before it may be relied upon in reaching a legal decision. Legal systems should be committed to an emergent rule of law ideal identified and referred to as "intellectual due process" which condemns epistemically arbitrary reasoning processes insofar as they play a role in legal decisionmaking. Since non-arbitrariness is a necessary condition of both epistemic and legal legitimacy, we have compelling reason to doubt that the non-arbitrariness condition can be met when non-experts defer epistemically to scientific experts.

According to an attractive and widely held view, all practical reasons are explained in terms of the (instrumental or final) value of the action supported by the reason. I argue that this theory is incompatible with plausible assumptions about the practical reasons that correspond to certain moral rights, including the right to a promised action and the right to an exclusive use of one’s property. The argument is an explanatory rather than extensional one: while the actions supported by (...) the relevant reasons (e.g. keeping a valid promise or respecting property) can be argued to have a certain kind of value, I argue that this value presupposes a moral right, and therefore cannot explain the reason. Reflection on such cases suggest the conclusion that reasons that are subject to normative powers are generally not value-based. This also has important implications for the dialectic between ‘value-first’ and ‘reasons-first’ approaches to normativity. (shrink)

In this essay, I argue that the objections that have been raised against the view that equality is intrinsically valuable also provide objections to the view that all practical reasons can be explained in terms of value. Plausible egalitarian principles entail that under certain conditions people have claims to an equal share. These claims entail reasons to distribute goods equally that cannot be explained by value if equality has no intrinsic value.

In this paper, I focus on the most important form of argument for anti-intellectualism, one that exploits alleged connections between knowledge and practical reasoning. I first focus on a form of this argument which exploits a universal principle, Sufficiency, connecting knowledge and practical reasoning. In the face of putative counterexamples to Sufficiency, a number of authors have attempted to reformulate the argument with a weaker principle. However, I argue that the weaker principles suggested are also problematic. I conclude (...) that, so far, there is no good argument for anti-intellectualism that rests on connections between knowledge and practical reasoning.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

We have it on the authority of Aristotle that “reason (nous) is the best thing in us” (EN X.7, 1177a20). This idealization of reason permeates his account of eudaimonia, a term commonly translated as ‘happiness’, which Aristotle identifies with living and doing well (EN I.4, 1095a18-20). In harmony with a certain intellectualism peculiar to the mainstream of ancient philosophical accounts of eudaimonia, Aristotle holds that living well requires the unique practical application of rationality of which only humans are capable (...) (EN I.7, 1098a13-15/EE I.7, 1217a25-27). This dissertation investigates Aristotle’s substantive view on the practical application of reason by examining how, according to him, human agents use reason to decide what to do, what kind of person to be, and indeed how to live well. A distinctively human way of making decisions is deliberation (bouleusis), an exercise of practical reason par excellence. The first chapter reconstructs Aristotle’s account of deliberation from a wide range of texts in the corpus. It argues that deliberation is a complex decision-making process that, for the most part, unfolds into four stages: (1) positing a provisional goal; (2) constructing a set of alternatives; (3) identifying the best alternative; (4) forming an intention to do the most proximate action as identified in the penultimate stage. This reading offers a comprehensive representation of Aristotle’s theory while rendering his theory more sophisticated—and indeed more modern—than the alternatives in recent years. Deciding what to do often requires that we confront the question, “Which is preferable (hairetōteron) or better (beltion) between two or more options?” In Topics III, a text widely acknowledged as the inaugural treatment of the logic of preference, Aristotle articulates a set of principles to guide our preference-ranking. While scholars pay historical homage to Aristotle, there is little engagement with his treatment of preference logic. The second chapter addresses the need for a current study and reassessment of Aristotle’s preference-ranking principles. It argues that, despite differences in scope and methodology between the Aristotelian and modern systems, the description inaugural treatment of preference logic comfortably, and accurately, applies to Topics III. When one looks at the role that Aristotle allows reason to play in the production and motivation of action, it is tempting to conclude that Aristotle endorses the Humean division of labor. For Aristotle claims that deliberation is about “the things towards the goal” (EN III.3, 1112b11-16) and that virtue (aretē) makes our goals right (EN VI.12, 1144a7-9). Chapter three seeks to show, against a recent influential quasi-Humean interpretation, that the primary function of practical reason is mapping the landscape of value corresponding to the agent’s reasoned conception of what eudaimonia consists in, as a rational being that she is. Aristotle notoriously defends the political subordination of individuals he believes to have a defective deliberative capacity. In Politics I.13, he claims that the deliberative faculty is undeveloped in children and “ineffectual” (akuron) in women (1260a12). The concluding chapter considers a puzzle about the development of the female’s deliberative faculty: How do women become ineffective in their deliberation, but freemen do not, given that all children have deliberative faculties that are unperfected? Drawing from the theories defended in previous chapters, I argue that the female’s deliberative defect is primarily due to her lack of moral education rather than inalterable sexual, biological differences—a thesis widely endorsed by scholars lately.

Focusing on millennials, individuals born between 1980 and 2000 and representing the largest generational population in our history, this research seeks to understand their ethical decision-making processes by exploring the distinctive, yet interconnected, theories of personal values and cognitive moral reasoning. Utilizing a decision-making framework introduced in the 1990s, we discover that there is a statistically supported relationship between a millennial’s personal value orientation and stage of cognitive moral reasoning. Moreover, we discover a strong relationship between three of (...) the four value orientations and a corresponding stage of cognitive moral reasoning. The theoretical and practical research implications of our discovery about millennials’ decision making are discussed. (shrink)

Ethics Done Right examines how practical reasoning can be put into the service of ethical and moral theory. Elijah Millgram shows that the key to thinking about ethics is to understand generally how to make decisions. The papers in this volume support a methodological approach and trace the connections between two kinds of theory in utilitarianism, in Kantian ethics, in virtue ethics, in Hume's moral philosophy, and in moral particularism. Unlike other studies of ethics, Ethics Done Right does not (...) advocate a particular moral theory. Rather, it offers a tool that enables one to decide for oneself. (shrink)

Reason and Value collects 15 new papers by leading contemporary philosophers on themes from the work of Joseph Raz. Raz has made major contributions in a wide range of areas, including jurisprudence, political philosophy, and the theory of practical reason; but all of his work displays a deep engagement with central themes in moral philosophy. The subtlety and power of Raz's reflections on ethical topics make his writings a fertile source for anyone working in this area. Especially significant are (...) his explorations of the connections between practical reason and the theory of value, which constitute a sustained and penetrating treatment of a set of issues at the very center of moral philosophy as it is practiced today. The contributors to the volume acknowledge the importance of Raz's contributions by engaging critically with his positions and offering independent perspectives on the topics that he has addressed. The volume aims both to honour Raz's accomplishments in the area of ethical theorizing, and to contribute to an enhanced appreciation of the significance of his work for the subject. (shrink)

Two goods are incommensurable just in case neither is better than the other, nor are they equal. Incommensurable goods pose two problems: determining which goods are incommensurable, and deciding how to make choices over those that are. In this dissertation, I develop a theory of value and show how it solves these two problems. An item is good, I argue, insofar as there are reasons to choose it. Accordingly, the comparative value of two goods depends upon the reasons for choosing (...) between them. I then argue that goods are commensurable when practical reason supports certain patterns of choice over them, and that they are incommensurable when it supports certain other patterns. We therefore have reason to think goods are incommensurable when our practical reasons commit us to certain patterns of choice over them. This result solves both problems: practical reason not only tells us when goods are incommensurable, but does so by telling us how to make choices over them. (shrink)

In this book, German philosopher Julian Nida-Rümelin presents a theory of practical reason that is objectivist, or rather realist, as an alternative to the widespread subjectivism in the theory of rationality. This theory has pragmatic traits that can be read as a constructive counterpart to Nida-Rümelin's critique of consequentialism whilst embedding its conception of rationality in the conceptual framework of decision and game theory.

Building upon the role values take in Walton’s theory of practical reasoning, this paper will frame the question of how values should be evaluated into the broader question of what reasonable practical argumentation is. The thesis argued for is that if a positive evaluation of practical reasoning argumentation requires that the argument avoid a morally negative conclusion, then the role of values should be given a central, rather than supportive, position in practical argument evaluation.

This paper begins by reviewing dominant themes in current teaching of professional ethics in engineering education. In contrast to more traditional approaches that simulate ethical practice by using ethical theories to reason through micro-level ethical dilemmas, this paper proposes a pragmatic approach to ethics that places more emphasis on the practical plausibility of ethical decision-making. In addition to the quality of ethical justification, the value of a moral action also depends on its effectiveness in solving an ethical dilemma, (...) cultivating healthy working relationships, negotiating existing organizational cultures, and achieving contextual plausibility in everyday professional practice. This paper uses a cross-cultural ethics scenario to further elaborate how a pragmatic approach can help us rethink ethical reasoning, as well as ethics instruction and assessment. This paper is expected to be of interest to educators eager to improve the ability of engineers and other professional students to effectively and appropriately deal with the kinds of everyday ethical issues they will likely face in their careers.

This paper proposes a concept of "valid reasoning" that will apply univocally to reasoned judgment (inference), Reasoned decision (choice), And reasoned withholding of judgment and decision. "reasoning" is taken to include all these; "validity" of reasoning is defined in terms of the "ideally rational mind", Which is in turn defined by a modal logic of judging and deciding. The definition is defended by relating it to another ideal, That of the socratically omniscient and stoically omniscient sage, Who is (...) defined by a modal logic of knowing and doing. In the course of this I distinguish between the vehicle and the description of a mental act, Deny that reasoning is a transition, Analyze doing as causing to be, And maintain that, Since doing stands to deciding as knowing stands to judging, Reasoned decision is genuinely practical reasoning.

Background: Priority setting is necessary in current healthcare services. Discussion of fair process has highlighted the value of developing reasons for allocation decisions on the basis of experience gained from real cases.Aim: To identify the reasons that those with experience of real decision-making concerning resource allocation think relevant in deciding on the priority of a new but expensive drug treatment.Methods: Semistructured interviews with members of committees with responsibility for making resource allocation decisions at a local level in the British (...) National Health Service, analysed using modified grounded theory.Results: 22 interviews were carried out. 14 reasons were identified. Four reasons were almost universally considered most important: cost effectiveness; clinical effectiveness; equality and gross cost. No one reason was considered dominant. Some considerations, such as political directives and fear of litigation, were thought by many participants to distort decision-making. There was a substantial lack of agreement over the relevance of some reasons, such as the absence of alternative treatment for the condition.Conclusions: There is a clear consensus on the importance and role of a limited number of reasons in allocation decisions among participants. A focus on the process of decision-making, however, does not obviate the need for those involved in the process to engage with problematical ethical issues, nor for the importance of further ethical analysis.

While differing widely in other respects, both neo-Humean and neo-Kantian approaches to normativity embrace an internalist thesis linking reasons for acting to potential motivation. This thesis pushes in different directions depending on the underlying view of the powers of practical reason, but either way it sets the stage for an attack on realist attempts to ground reasons directly in facts about value. How can reasons that are not somehow grounded in motivational features of the agent nonetheless count as reasons (...) for that particular agent, having genuine normative force for her? Won't any realist, externalist view threaten to alienate the individual from the reasons that obtain for her, particularly if she fails (even after rational deliberation) to care about the values that are supposed to ground them? I argue that such objections can successfully be answered, and that externalist views of reasons need not be plagued with normative alienation. Focusing largely on a recent debate between Williams and McDowell over the nature of normative reasons, I show that a value-based externalist theory, when properly conceived, can account for the normative relevance of reasons to the particular agents for whom they obtain. Moreover, Williams's own sophisticated neo-Humeanism turns out to be vulnerable to parallel charges of normative alienation, which it cannot escape without compromising the very psychologistic orientation that has been its chief attraction. Realist externalism about reasons turns out to be a more viable and attractive alternative to both neo-Humeanism and neo-Kantianism than many currently take it to be. (shrink)

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers.".

“Since today is Saturday, the grocery store is open today and will be closed tomorrow; so let’s go today”. That is an example of everyday practical reasoning—reasoning directly with the propositions that one believes but may not be fully certain of. Everyday practical reasoning is one of our most familiar kinds of decisions but, unfortunately, some foundational questions about it are largely ignored in the standard decision theory: (Q1) What are the decision rules in everyday (...) class='Hi'>practical reasoning that connect qualitative belief and desire to preference over acts? (Q2) What sort of logic should govern qualitative beliefs in everyday practical reasoning, and to what extent is that logic necessary for the purposes of qualitative decisions? (Q3) What kinds of qualitative decisions are always representable as results of everyday practical reasoning? (Q4) Under what circumstances do the results of everyday practical reasoning agree with the Bayesian ideal of expected utility maximization? This paper proposes a rigorous decision theory for answering all of those questions, which is developed in parallel to Savage’s (1954) foundation of expected utility maximization. In light of a new representation result, everyday practical reasoning provides a sound and complete method for a very wide class of qualitative decisions; and, to that end, qualitative beliefs must be allowed to be closed under classical logic plus a well-known nonmonotonic logic—the so-called system ℙ.

This paper compares current ways of modeling the inferential structure of practical reasoning arguments, and proposes a new approach in which it is regarded in a modular way. Practical reasoning is not simply seen as reasoning from a goal and a means to an action using the basic argumentation scheme. Instead, it is conceived as a complex structure of classificatory, evaluative, and practical inferences, which is formalized as a cluster of three types of distinct and interlocked argumentation (...) schemes. Using two real examples, we show how applying the three types of schemes to a cluster of practical argumentation allows an argument analyst to reconstruct the tacit premises presupposed and evaluate the argumentative reasoning steps involved. This approach will be shown to overcome the limitations of the existing models of practical reasoning arguments within the BDI and commitment theoretical frameworks, providing a useful tool for discourse analysis and other disciplines. In particular, applying this method brings to light the crucial role of classification in practical argumentation, showing how the ordering of values and preferences is only one of the possible areas of deep disagreement.

There are three steps in my description of the ground-problem of value: First, Husserl’s analysis of the crisis of reason is based on the systematic loss and phenomenological recovery of the intuitive evidence of the lifeworld. But if letter symbols are essential to formalizing abstraction, as Klein’s de-sedimentation of Vieta’s institution of modern algebra shows, then the ultimate substrates upon which formalization rests cannot be “individuals” in Husserl’s sense. The consequence of the essentiality of the letter symbols to formalization is (...) that no direct reference to intuitive evidence of individuals is possible from formal structures. Second, the crisis of reason in Marx’s Capital on commodities contains a parallel analysis of the contradictory relation between formalism and evidence. The value-structure of capitalist society expels qualitative value to subjective use and imposes a homogeneous standard on social representation of value such that quantitative values are not grounded in the experience of use which entails that the system of general value becomes a mere aggregate. Third, the problem of value, or formal axiology, is the core of a teleological convergence between phenomenology and Marxism. A short phenomenological description of the experience of value shows that practical activities generate valuations that are experienced with an intensity through which they aim toward social representation. The conclusion is that the social representation of value in capitalist society intervenes into the constitution of the community by the intensity of individuals’ value-experience to reduce its system of value to an unthematized simple aggregate of value-quantities.

Many irreconcilable accounts of ratio legis in legal science, often concerned with legal interpretation, suffer from being disconnected from practical reasoning. Different theories of legal interpretation which result in one-sided views of ratio legis are by-products of one-sided semantics. The first part of the chapter diagnoses this problem by providing a model of three types of one-sided semantics—upstream, midstream and downstream—and explaining how they translate into respective accounts of legal interpretation and ratio legis. The second part of the chapter (...) presents an alternative to one-sided semantics in legal theory. The alternative account which combines semantics and practical reasoning in legal theory is based on Brandom’s inferential pragmatism. The usefulness of inferential pragmatism in legal theory with regard to the problem of ratio legis is tested and followed by extending an inferentialist account of ratio legis provided by Canale and Tuzet. A model of agent’s actions and reasons, and their impact on the reasoning of interpreters and decision-makers is the essential part of this extension. (shrink)

Several philosophers have proposed Knowledge-Based Decision Theories (KDTs)—theories that require agents to maximize expected utility as yielded by utility and probability functions that depend on the agent’s knowledge. Proponents of KDTs argue that such theories are motivated by Knowledge-Reasons norms that require agents to act only on reasons that they know. However, no formal derivation of KDTs from Knowledge-Reasons norms has been suggested, and it is not clear how such norms justify the particular ways in which KDTs relate knowledge (...) and rational action. In this paper, I suggest a new axiomatic method for justifying KDTs and providing them with stronger normative foundations. I argue that such theories may be derived from constraints on the relation between knowledge and preference, and that these constraints may be evaluated relative to intuitions regarding practical reasoning. To demonstrate this, I offer a representation theorem for a KDT proposed by Hawthorne and Stanley (2008) and briefly evaluate it through its underlying axioms. -/- In section 1, I present knowledge-based decision theories generally and the versions of such theories suggested in the literature. In section 2, I argue that KDTs and theories of practical reasoning conjoined with Knowledge-Reasons norms generate constraints on the same relation—the relation between knowledge and preference. In section 3, I present a formal framework in which constraints on this relation may be expressed and from which KDTs may be derived. In section 4, I present a representation theorem for a specific KDT. In section 5, I briefly evaluate the axioms of the theory, and in section 6, I conclude. (shrink)

This paper introduces a logical analysis of convex combinations within the framework of Łukasiewicz real-valued logic. This provides a natural link between the fields of many-valued logics and decision theory under uncertainty, where the notion of convexity plays a central role. We set out to explore such a link by defining convex operators on MV-algebras, which are the equivalent algebraic semantics of Łukasiewicz logic. This gives us a formal language to reason about the expected value of bounded random variables. (...) As an illustration of the applicability of our framework we present a logical version of the Anscombe–Aumann representation result. (shrink)

In the last half century, decision theory has had a deep influence on moral theory. Its impact has largely been beneficial. However, it has also given rise to some problems, two of which are discussed here. First, issues such as risk-taking and risk imposition have been left out of ethics since they are believed to belong to decision theory, and consequently the ethical aspects of these issues have not been treated in either discipline. Secondly, ethics has adopted the (...) decision-theoretical idea that action-guidance has to be based on cause–effect or means–ends relationships between an individual action and its possible outcomes. This is problematic since the morally relevant connections between an action and future events are not fully covered by such relationships. In response to the first problem it is proposed that moral theory should deal directly and extensively with issues such as risk-taking and risk imposition, thereby intruding unabashedly into the traditional territory of decision theory. As a partial response to the second problem it is proposed that moral theorizing should release itself from the decision-theoretical requirement that the moral status of an action has to be derivable from the consequences (or other properties) that are assignable to that action alone. In particular, the effects that an action can have in combination with other actions by the same or other agents are valid arguments in an action-guiding moral discourse, even if its contribution to these combined consequences cannot be isolated and evaluated separately.

Utilitarian (U.) theories must be capable of being applied in practical reasoning, or they would have no value as a guide to rational conduct. However, I show that epistemic extensions to U. theories produce logical confusion. Basic questions about what one needs to know in order to apply a U. analysis embroil one in an infinite regress. And attempts to incrementally apply U. either are no help at all (leaving one entirely 'in the dark'), or in general constitute arbitrary (...) gambles which no practical reasoner could defend taking. These problems are serious enough to completely discredit U. theories as having any relevance to practical reasoning. (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’.

A love-based reason theory as a new perspective in the debate on practical reasons. Reasons and obligations pervade our lives. The alarm clock gives us a reason to get up in the morning, the expectations of colleagues or clients give us a reason to do our jobs well, the misery in developing countries gives us a reason to donate money, headaches give us a reason to take an aspirin. Looking for unity in variety, philosophers wonder what makes a consideration (...) count as a reason to do something. The nature and source of practical reasons has been debated intensively over the last three decennia in analytic philosophy. This book discusses the three most influential theories in current debates, referred to as the desire-based, the value-based, and the rationality-based theories of practical reasons. The author argues that all three are defective because they overlook the role of what agents care about. (shrink)

It can be assumed that value judgements, which are needed to judge what is ‘good’ or ‘better’ and what is ‘bad’ or ‘worse’, are involved in every decision-making process. The theoretical understanding and analysis of value judgements is, therefore, important in the context of bioethics, for example, to be able to ethically assess real decision-making processes in biomedical practice and make recommendations for improvements. However, real decision-making processes and the value judgements inherent in them must first be (...) investigated empirically (‘empirical bioethics’). For this to succeed, what exactly a ‘value judgement’ is and of what components it might consist must initially be theoretically clarified. A corresponding conceptual model can then support or even enable empirical data collection and analysis and, above all, subsequent ethical analysis and evaluation. This paper, therefore, presents a value judgement model with its theoretical derivation. It also illustrates its application in an interview study of decision-making between animal experimentation and alternative methods in the context of biomedical research. Though the model itself can be theoretically deepened and extended, the application of the model works in general and helps to uncover what value judgements can enter into decision-making. However, the empirical methods, for example, qualitative interviews, can also be better oriented towards eliciting value judgements (as understood according to the model). Further applications of the model to other topics or by means of other empirical methods are conceivable. (shrink)

2nd edition. Many-valued logics are those logics that have more than the two classical truth values, to wit, true and false; in fact, they can have from three to infinitely many truth values. This property, together with truth-functionality, provides a powerful formalism to reason in settings where classical logic—as well as other non-classical logics—is of no avail. Indeed, originally motivated by philosophical concerns, these logics soon proved relevant for a plethora of applications ranging from switching theory to cognitive modeling, and (...) they are today in more demand than ever, due to the realization that inconsistency and vagueness in knowledge bases and information processes are not only inevitable and acceptable, but also perhaps welcome. The main modern applications of (any) logic are to be found in the digital computer, and we thus require the practical knowledge how to computerize—which also means automate—decisions (i.e. reasoning) in many-valued logics. This, in turn, necessitates a mathematical foundation for these logics. This book provides both these mathematical foundation and practical knowledge in a rigorous, yet accessible, text, while at the same time situating these logics in the context of the satisfiability problem (SAT) and automated deduction. The main text is complemented with a large selection of exercises, a plus for the reader wishing to not only learn about, but also do something with, many-valued logics. (shrink)

ABSTRACT: Confronted with the “wrong kind of reason problem”, several proponents of the fitting attitude analysis of emotional values have argued in favor of an epistemic approach. In such a view, an emotion fits its object because the emotion is correct. However, I argue that we should reorient our search towards a practical approach because only practical considerations can provide a satisfying explanation of the fittingness of emotional responses. This practical approach is partially revisionist, particularly because it (...) is no longer an analysis of final value and because it is relativistic.

Normative judgments are typically subject to emotional reasons that cannot be justified by reference to facts alone. As a result, practical disputes sometimes go unsettled in ways that support James Lenman's view of moral inquiry as politics. An important consequence is that reasonableness is often preferable to truth as a criterion of good practical judgment. Although the role of emotions suggests metaethical expressivism as preferable to realism for analysing practical reasoning, reasonableness transforms expressivism from a form of (...) noncognitivism into a theory that recognizes cognitively rich forms of approval and disapproval. Defensible normative intuitions have good justifying reasons even when these reasons permit faultless differences of political opinion and ethical practice. Despite implying deep normative pluralism, however, a cognitivist form of expressivism explains how deliberative agents can construct and maintain reasonable moral communities. (shrink)

This book covers a wide spectrum of connected topics in the field of practical and moral thinking. It contains papers and discussions on the logic of practical reasoning and moral obligation; on the decision-theoretical approach to morality; on the relation between practical and theoretical reason; and on the political aspects of morality. The contributors are, for the most part, well-known philosophers who have not been content with merely restating their positions, but have sued this as a (...) forum for proposing new ideas. The value of the collection lies not only in the originality of the contributions on the various topics mentioned but equally in its demonstration of the interrelations among these topics. (shrink)

How do we think about what we plan to do? One dominant answer is that we select the best possible option available. However, a growing number of philosophers would offer a different answer: since we are not equipped to maximize we often choose the next best alternative, one that is no more than satisfactory. This strategy choice is called satisficing. This collection of essays explores both these accounts of practical reason, examining the consequences for adopting one or the other (...) for moral theory in general and the theory of practical rationality in particular. It aims to address a constituency larger than contemporary moral philosophers and bring these questions to the attention of those interested in the applications of decision theory in economics, psychology and political science.

When a patient lacks decision-making capacity and has not left a clear advance directive, there is now widespread agreement that patient-designated and next-of-kin surrogates should implement substituted judgment within a process of shared decision-making. Specifically, after discussing the “best scientific evidence available, as well as the patient's values, goals, and preferences” with the patient's clinicians, the patient-designated or next-of-kin surrogate should attempt to determine what decision the patient would have made in the circumstances. To the extent that (...) this approach works, it seems to provide about as much respect for the autonomy of incapacitated patients as we could ask for. But, as articles in this issue of the Report by Jeffrey Berger and by Ellen Robinson and colleagues emphasize, reality presents challenges. (shrink)

Practical reasons, roughly, are reasons to have our desires and goals, and to do what might secure these goals. I argue for the view that lack of freedom to do otherwise undermines the truth of judgments of practical reason. Thus, assuming that determinism expunges alternative possibilities, determinism undercuts the truth of such judgments. I propose, in addition, that if practical reason is associated with various values in a specified way, then determinism precludes such values owing to determinism's (...) imperiling practical reason.
