If the task of theoretical reason is to discover truth, or reasons for belief, then theoretical reason is impossible. Attempts to circumvent that by appeal to probabilities are self-defeating. If the task of practical reason is to discover what we ought to do or what actions are desirable or valuable, then practical reason is impossible. Appeals to the subjective ought or to subjective probabilities are self-defeating. Adapting Karl Popper, I argue that the (...) task of theoretical reason is to obtain theories that we can agree to instate given that they appear to have greater explanatory merit than their rivals. I then argue that the task of practical reason is to decide which ought-propositions to act on. As a consequence theoretical reason is seen as a branch of practical reason. This approach makes both theoretical and practical reason practicable and free of the defects of the usual accounts. (shrink)

Traditional philosophy of science regards theoretical reasoning, based on the example of Euclidian geometry, as the hallmark of a mature science. There is, however, a parallel tradition of practical reasoning based on specific cases that goes back to Aristotle. In this paper I argue that practical reasoning is an essential part of the practice of chemistry and should be understood and appreciated on its own merits rather than regarded as a symbol of the immaturity and inferiority of (...) chemistry as a science.

The article focuses on re-evaluating Kant’s Transcendental Dialectic by initially highlighting its seemingly negative function within the Critique of Pure Reason as a mere regulative form for cognition and experience. The Dialectic, however, does not only have such a negative-regulative function but also its very own positive and founding character for cognition that even is present in the supposedly most immediate forms of intuition. In exploring this positive side of the Transcendental Dialectic it becomes clear that it manifests itself (...) as a bridge between the so-called theoretical and practical reason inasmuch as it fills in their gap within Kant’s philosophy. From the practical side, the Dialectic is manifest as an action full of purposiveness, maxims, and imperatives within cognition, from a theoretical side it assumes the form of syllogistic inference, which is the adequate and acting theoretical form of practical reason. Therefore, the unity of reason is shown in presenting its inner gap as a dialectical misunderstanding that Kant not only highlights in the Transcendental Dialectic but also tends to leave unsolved mostly. Nevertheless, the Dialectic can be shown as the a priori synthetic act of unifying reason, if investigated in the context of Kant’s complete critical endeavour. (shrink)

The aim of this essay is to provide a philosophical discussion of Frederick Douglass's thought in relation to Christianity. I expand upon the work of Bill E. Lawson and Frank M. Kirkland—who both argue that there are Kantian features present in Douglass as it relates to his conception of the individual—by arguing that there are similarities between Douglass and Kant not only concerning the relationship between morality and Christianity, but also concerning the nature of the soul. Specifically, I try to (...) show that the moral weakness of slaveholding Christianity that Douglass attacked is found in the ecclesial formation of the slaveholding Christian church; it is a formation that begins with epistemology, but ignores ethics. I conclude, in part, that both Douglass and Kant reject a Cartesian psychological dualism in favor of a conception of the soul that is more attentive to one's moral development. (shrink)

In his critical works of the 1780's, Kant claims, seemingly inconsistently, that (1) theoretical and practical reason are one and the same reason, applied differently, (2) that he still needs to show that they are, and (3) that theoretical and practical reason are united. I first argue that current interpretations of Kant's doctrine of the unity of reason are insufficient. But rather than concluding that Kant’s doctrine becomes coherent only in the Critique (...) of Judgment, I show that the three statements are compatible, providing a new and more coherent account of Kant's 1780's doctrine of the unity of reason.

Pensar além dos limites do possível conhecimento empírico requer uma razão subjetiva para legitimar seus juízos. De acordo com Kant, esta reside no sentimento de uma "necessidade da razão", que, por sua vez, deve ser justificado como tal. Para isto, é reclamado um especial "direito da necessidade" da razão, como “fundamento subjetivo para supor e admitir algo [...] que ela com fundamento objetivo não pode presumir saber" [08:137]. Ao contrário da necessidade da razão teórica e da sua satisfação por meras (...) hipóteses, a necessidade prática da razão é incondicional, porque aqui não só "queremos julgar, mas devemos [...] julgar" [08:139]. – A seguir, as condições específicas deste "dever" - os "postulados" morais – serão examinadas criticamente.

Stanovich & West continue a history of norm-setting that began with deference to reasonable people's opinions, followed by adherence to probability theorems. They return to deference to reasonable people, with aptitude test performance substituting for reasonableness. This allows them to select independently among competing theories, but defines reasoning circularly in terms of aptitude, while aptitude is measured using reasoning.

Given the success of the formal approach, within contemporary epistemology, to understanding degreed belief, some philosophers have recently considered its extension to the challenge of understanding intention. According to them, (1) intentions can also admit of degrees, as beliefs do, and (2) these degreed states are all governed by the norms of the probability calculus, such that the rational norms for belief and for intention exhibit certain structural similarity. This paper, however, raises some worries about (2). It considers two schemes (...) for representing degreed intention, and casts some doubt on applying probabilistic norms to degreed intention on each scheme. And it argues that the norms of Intention–Belief Consistency and Enkrasia cannot plausibly be turned into norms prescribing a simple correspondence relation between one’s degrees of belief and intention. The results suggest a potential structural discrepancy between the norms of theoretical and practical rationality—at least for degreed belief and intention. This potential discrepancy not only raises interesting questions about the intention–belief relation and rational norms for degreed intention. It also poses a new challenge for intention-based expressivism about normative judgment and cognitivism about practical rationality. (shrink)

In this paper I argue that if one is to do justice to reason's unity in Kant, then one must acknowledge that reason's practical ends are presupposed in every theoretical investigation of nature. Thus, contrary to some other commentators, I contend that the notion of the metaphysical ground of the unity of nature should not be attributed to the “dynamics of reason” and its “own practical purposes.” Instead, the metaphysical ground of the unity of (...) nature is in fact an indispensable and necessary notion for reason in both its theoretical and practical functions, but this need of reason to presuppose such a notion can only find its adequate proof in the practical. By offering a synopsis of Kant's accounts of nature's systematicity in the Transcendental Ideal of the Critique of Pure Reason (Part I), the Appendix to the Dialectic of the Critique of Pure Reason (Part II), and in the Critique of Judgment (Part III), I identify in each section Kant's theoretical and practical arguments for reason's presupposition of the “unconditioned,” demonstrate their structural interdependence, and show a general continuity in Kant's position on this issue throughout his critical system.

This new volume addresses the central questions which surround the process of reasoning. This emerging topic of analytic philosophy intersects with numerous other areas of philosophy, such as epistemology, philosophy of mind, philosophy of language, and metaethics, and also psychological work on reasoning.

Philosophers have always recognized the value of reason, but the process of reasoning itself has only recently begun to emerge as a philosophical topic in its own right. Is reasoning a distinctive kind of mental process? If so, what is its nature? How does reasoning differ from merely freely associating thoughts? What is the relationship between reasoning about what to believe and reasoning about how to act? Is reasoning itself something you do, or something that happens to you? And (...) what is the value of reasoning? Are there rules for good or correct reasoning and, if so, what are they like? Does good reasoning always lead to justified belief or rational action? Is there more than one way to reason correctly from your evidence? This volume comprises twelve new essays by leading researchers in the philosophy of reasoning that together address these questions and many more, and explore the connections between them. (shrink)

Philosophers have often noted a contrast between practical and theoretical reasons when it comes to cases involving equally balanced reasons. When there are strong practical reasons for A-ing, and equally strong practical reasons for some incompatible option, B-ing, the agent is permitted to make an arbitrary choice between them, having sufficient reason to A and sufficient reason to B. But when there is strong evidence for P and equally strong evidence for ~ P, one (...) isn’t permitted to simply believe one or the other. Instead, one must withhold belief, neither believing that P nor believing that ~ P. This paper examines what explains this contrast, focusing in particular on a proposal recently developed by Mark Schroeder across several papers. Schroeder aims to explain the contrast by an appeal to non-evidential, epistemic reasons against belief. But, I argue, it’s not clear exactly what those reasons are, nor how those reasons are to be weighed against evidential reasons. Despite these challenges, I argue that there are grounds for optimism that the contrast can be explained within the broad framework Schroeder provides, and I aim to provide resources to meet the aforementioned challenges.

The conventional interpretation of Thomas Aquinas's concept of "moral science" casts it as a knowledge of moral rules that are the outcome of a deductive method of theoretical reason. However, there is a practical moral science that is possessed by ordinary people who are capable of a moral wisdom that is not derived from philosophy. The doctrine concerning this moral science is found in the texts of Aquinas as he takes up and strengthens the philosophy of Aristotle. (...) This book examines how moral science, then, is not a theoretical set of conclusions imposed on the will, but it is rather the grasping of a whole set of human ends that are intellectually apprehended by a compositive method.

Certainty and Practical Reason is concerned with Kant's practical response to epistemological skepticism and radical doubt. ;It begins from Kant's remark that the concept of freedom is the keystone of the arch of reason, theoretical as well as practical, and sustains reason against skepticism; and from Kant's account of the practical motives of transcendental realism, the source of skepticism, in the First and Second Critiques. The Critiques suggest both that Kant's response to (...) skepticism is practical, and that skepticism is itself both practically motivated and associated with practical error. ;In the first chapter, it is argued that the Transcendental Analytic of the First Critique is not a final refutation of skepticism and radical doubt, and that Kant does not see it as such. The theoretical arguments of the Transcendental Analytic need to be completed with an appeal to practical reason if we are to ground Kant's starting assumption, the fact of experience. ;The second chapter considers epistemological skepticism as involving a practical error answered by the practical cure of the categorical imperative. ;The third chapter begins by considering Cartesian doubt as a practically motivated attempt to pose the problem of practical rationality, and Kant's response to this problem. It then discusses Kant's view that the transcendental realist demand for knowledge of the noumenal, which gives rise to skeptical doubt, is a pursuit of the unconditioned whose hidden meaning is practical; and explains how Kant responds to the doubt by responding to and interpreting transcendental realism as a practical project. ;The fourth chapter discusses the Critique of Judgment as a response to "enthusiasm" or the transcendental realist claim to knowledge of the unconditioned, and thereby to skepticism as well.

It has been argued by several writers that practical reasoning is capable of a kind of validity that is unlike the validity which theoretical reasoning can possess. One can gain an initial impression of this view's appeal, as well as of its content, by seeing how it could issue from analytical reflection upon the idea that actions, decisions and intentions all can be, and frequently are, reasonable . An inviting first step in such reflection is to say that (...) for a certain intention, say, to be reasonable on a certain occasion is, roughly, for it to be true that a person could come to have that intention as a result of reasoning well about what to do. One might then add the further thought that, so far as regards what it is for a piece of reasoning to be well done, reasoning falls into at least two basic kinds: reasoning about what to do differs generically from reasoning about what is the case. The view which I mentioned at the outset can now be seen as a specific proposal regarding where this difference lies: reasoning about what to do has distinctive validity-conditions not shared by reasoning about what is the case.

The power of skepticism depends on the apparent possibility of rationally asking, for virtually any kind of proposition commonly thought to be known,howit is known or what justifies believing it. Moral claims are among those commonly subjected to skeptical challenges and doubts, even on the part of some people who are not skeptical about ordinary claims regarding the external world. There may be even more skepticism about the possibility of justifying moralactions,particularly if they are against the agent's self-interest. Both problems-how (...) to justify moral claims and how to justify moral action - come within the scope of the troubling question “Why be moral?” Even a brief response to moral skepticism should consider both kinds of targets of justification, cognitive and behavioural, and should indicate some important relations between the two types of skeptical challenge. I will begin with the cognitive case- with skepticism about the scope of theoretical reason in ethics - proceed to practical skepticism, which concerns the scope of practical reason, and then show how an adequate account of rationality may enable us to respond to moral skepticism.

It has become increasingly common to interpret Hume as a `sceptic' of practical reason. This means that Hume supposedly contests, not only the ability of reason to provide demonstrable truths, in the conventional rationalist sense, but also reason's ability to guide our practical action. Proponents of this reading include Jean Hampton, Elijah Millgram and Christine Korsgaard. If this `sceptical reading' of Hume is correct, he would lack the philosophical resources to justify his account of political (...) justice. However, if examined further, this sceptical reading begins with deep-seated Kantian presuppositions about the role and function of practical reason. The paper critiques these presuppositions, arguing that they must be set aside in order to appreciate more fully how Hume does indeed have a proper theory of practical reason. Specifically, Hume believes practical reason encompasses the discursive articulation and evaluation of human character traits and moral values within the social context. These articulatory and intersubjective dimensions of practical reasoning emphasized in the Humean account could provide further theoretical inspiration for communitarian critiques of contemporary liberalism.

Society is facing uncertainty on a multitude of domains and levels: usually, reasoning and decisions about political, economic, or health issues must be made under uncertainty. Among various approaches to probability, this chapter presents the coherence approach to probability as a method for uncertainty management.

Finally, the chapter presents selected psychological factors which impact probabilistic representation and reasoning and discusses what (...) society can and cannot learn from the coherence approach from theoretical and practical perspectives.

The paper constitutes a detailed critical commentary on Stephen Darwall’s Impartial Reason (Ithaca: Cornell University Press, 1983). Its central thesis is that Darwall’s attempt to integrate a naturalist theory of substantive reasons for acting with a neo-rationalist derivation of moral requirements from the very concept of practical rationality is faced with insurmountable theoretic problems. The author argues that anyone who would accept a plausible internalist account of reasons, that justificatory reasons for an agent to act are facts which (...) must be capable of motivating that agent under certain conditions, cannot establish on an a priori or rationalist basis claims for the intersubjective validity of reasons or substantive normative requirements of any kind, but rather must acknowledge that such claims are both irreducibly empirical and epistemically risky.

This chapter intervenes in recent debates in Kant scholarship about the possibility of a general logical alien. Such an alien is a thinker whose laws of thinking violate ours. She is third-personal as she is radically unlike us. Proponents of the constitutive reading of Kant’s conception of general logic accordingly suggest that Kant rules out the possibility of such an alien as unthinkable. I add to this an often-overlooked element in Kant’s thinking: there is reason to think that he (...) grants—and in fact presupposes—the possibility of a transcendental logical alien. Such an alien is a knower whose laws of experience purport to violate ours. She is first-personal as she is radically like us. In other words, she is us, insofar as we are alienated from ourselves and our experience. I go on to draw an analogy between her, a dogmatist, and another transcendental alien, an evil agent. Just as a dogmatist is alienated from her (our) experiential laws, an evil agent is alienated from her (our) moral law. These forms of theoretical and practical self-conceit require self-knowledge in the form of a critique of speculative or practical reason. In bringing this point out, I aim to shift from the question of whether logical laws constitute our thinking to the question of whether grasping our experiential and moral laws as our laws constitutes our reason.

This paper considers the accountability of professionals who are involved in situations of the failure of their organization to perform its expected role properly; the case of infant Caleb Ness, who died despite the surveillance of welfare agencies, is taken as an illustration. Following Bovens (?The Quest for Responsibility: Accountability and Citizenship in Complex Organisations?, Cambridge University Press, Cambridge, 1998), it is accepted that there is an irreducible element of individual personal responsibility when preventable organizational failures occur through professional incompetence (...) or corruption. The type of guidance available from specialized professional knowledge and from ethical codes is appraised. This is contrasted with various theoretical approaches to practical reasoning, which are offered as a more relevant perspective on professional misconduct. Practical reason necessarily addresses itself to a reality much more uncertain, fluid and contingent than envisaged by the standard conceptions of professional knowledge and ethics. Rather then being derived strictly from impersonal abstract rules and formal knowledge, practical reason in large part reflects the character and personality of its owner. It is argued that, since professional responsibility is always partly personal, professional misconduct can be understood as a failure of practical reason. (shrink)

This thought-provoking book explores the multifaceted phenomenon of objectivity and its relations to various aspects of the law and practical reasoning. Featuring contributions from an international group of researchers from differing legal contexts, it addresses topics relevant not only from a theoretical point of view but also themes directly connected with legal and judicial practice. Beginning with an introduction from the editors proposing a new account of the meaning of objectivity, the book is then divided into three broad (...) themes illuminated by this account. Chapters first address a range of problems linked to the relationship between objectivity and jurisprudence, before turning in the second part to an analysis of the functions of objectivity in legal interpretation. The final part then deals with the function of objectivity in practical reasoning. Offering a spectrum of scholarly insights within a coherent intellectual framework, this book will be a crucial read for scholars and graduate students of legal philosophy and legal theory. Its discussion of objectivity as it relates to legal practice and practical reasoning will also be of interest to practitioners such as judges, arbitrators and lawyers. (shrink)

Rationality and reasonableness can be illustrated as Janus-faced concepts, not only in a descriptive diagnosis but also in a normative construction of adjudication, and in the analysis of its practical and rhetorical effects. Considering such an illustration, the present reflection returns to the discussion on the relevance of rationality and reasonableness in legal interpretation, aiming at distinguishing and/or connecting principles and criteria, beyond formally logical and/or procedurally argumentative decision-making, and, thus, within a normatively practical adjudication. Such an approach (...) will be presented in two main steps. In a first step, the rationality/reasonableness dichotomy will be discussed within a constitutive connection between principles and criteria in adjudication, and understanding legal principles as normatively substantial foundations to legal criteria—the former as axiological references filtered into the juridical system and the latter as their concretizations, and whose practical adequacy is rhetorically assigned by the interpretive communities involved in/by adjudication, and normatively referred both to their practical accordance to the axiological normativity of the principles they shall presuppose and to their suitability as practical operators to the problematic relevance of the sub judice cases. In a second step, and consequently, encompassing the projection of legal interpretation, in semiotic and in practical-normative perspectives, in order to discuss their constituting practical relevance in adjudication, the rationality/reasonableness dichotomy will be experimented within formal-logical procedures and within practical-dialectical connections between juridical problem and juridical system—therefore stating a discussion on the foundations, the intentionality and the consequences of adjudication, amongst deduction and analogy.

This paper seeks a better understanding of the elements of practical reasoning: premises and conclusion. It argues that the premises of practical reasoning do not normally include statements such as ‘I want to ϕ’; that the reasoning in practical reasoning is the same as in theoretical reasoning and that what makes it practical is, first, that the point of the relevant reasoning is given by the goal that the reasoner seeks to realize by means of (...) that reasoning and the subsequent action; second, that the premises of such reasoning show the goodness of the action to be undertaken; third, that the conclusions of such reasoning may be actions or decisions, that can be accompanied by expressions of intention, either in action, or for the future; and that these are justified, and might be contradicted, in ways that are not only peculiar to them (i.e. in ways that diverge from those found in theoretical reasoning), but are distinctively practical, in that they involve reference to reasons for acting and to expressions of intention, respectively.1.

Two principles are central to Rational Causation. Causalism: Believing and acting for a reason are causal phenomena in the sense that there is in both domains a causal connection between ground and grounded. Equivalence: There is a necessary connection between something's being the reason why I believe or act and my taking it to favour the belief or action. Kieran Setiya argues that Causalism is false in the theoretical case and that Equivalence is false in the (...) class='Hi'>practical case. I reply to these and other arguments. (shrink)

This paper examines some Indian philosophical arguments that are understandable as transcendental arguments—i.e., arguments whose conclusions cannot be denied without self-contradiction, insofar as the truth of the claim in question is a condition of the possibility even of any such denial. This raises the question of what kind of self-contradiction is involved—e.g., pragmatic self-contradiction, or the kind that goes with logical necessity. It is suggested that these arguments involve something like practical reason—indeed, that they just are arguments against (...) the primacy of “theoretical reason.” This characterization illuminates a characteristically Indic appeal to ordinary language.

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)

I intend to show some of the limits of the decision-theoretic model in connection with the analysis of cognitive agency. Although the concept of maximum expected utility can be helpful for explaining the decision-making process, it is certainly not the primary motor that moves agents to action. Moreover, it has been noticed elsewhere that this model is inadequate to the analysis of single cases of practical reasoning. A theory is proposed that introduces a plan-structure as a basic idea. In (...) order to know its very conceptual scope, we need to accommodate that theory to a cognitive architecture whereby the rational and autonomous agent makes choices and deliberates between courses of action to achieve specific goals that are of its interest. The paper endeavours also to clarify the relationship between the different modules that should constitute the architecture of an agent to accomplish the requisites of efficiency and autonomy in a changeable and dynamic world.

The subject of my dissertation is "rationality". In this book I undertake a comprehensive, systematic and independent treatment of the problem of rationality. This furthers progress toward a general theory of rationality, one that represents and defends a uniform conception of reason. The structure and general outline are as follows: Part I: General Definition of the Concept; Part II: Rationality in the Theoretical Realm; Part III: Rationality in the Practical Realm (parts II and III are divided respectively (...) into A. Relative Reasons and B. Absolute Reasons); Part IV: Grounds for the Principle of Reason. My aim in this work is to prove that a conception of rationality as justification of our usage of language is more significant than has been classically recognized, without, however, reducing the concept of rationality. After a definition of the term is provided in the first chapter by means of language analysis, the following three questions are dealt with in the subsequent chapters: a) Exhaustion of rationality in relative reasons—i.e., is reasoning exhausted by reference to existing views and goals, or does rationality also exist in a strong sense? The latter would be the case if the views and goals referred to the relative conception must themselves be justified de novo. I argue that such an absolute justification of views and goals cannot be provided. To this end, in the theoretical domain, I discuss a question prominent in the debate over the rationality of worldviews, namely the question of whether the standards of theoretical rationality are merely culturally relative (chapter V.). Here I arrive at the position that standards of theoretical rationality are only transcultural insofar as there are goals which are not themselves culturally-dependent. With regard to practically fundamental goals, the core standards of modern science can be justified. This justification strategy therefore requires that such goals be established. In practical terms, first I address (in Chapter VII) the so-called "final justification" of norms problem. Here I discuss above all the transcendental-pragmatic proposal and the contractualist conception. According to my view, neither succeed in providing a final rational grounding for norms. That grounding pertains instead to the rationale for objectives, and Chapter VIII demonstrates that even a final justification of objectives is impossible. This does not mean, however, that a person's goals cannot be criticized as irrational. But the warrant in this case depends on the rules that govern the genesis of desires being accepted by the subject. b) If substantive rationality does not exist because no absolute grounding for opinions and goals can obtain, then the question of how strong or weak the concept of rationality is acquires further weight. On that basis, relative theoretical and practical rationality is examined in detail. I aim with this analysis of (relative) rationality to apprehend the structural parallelism between rationality in both the practical and the theoretical domain, and therefore to defend a uniform conception of reason or rationality. This is accomplished by identifying a concept that exhibits the same structure in both theoretical and practical domains: the term "rational" is applied to actions and opinions in order to claim, first of all, that they are "well-founded." For example, one must inquire into the precise rational justification for opinions or actions. To determine the individually necessary and jointly sufficient conditions required for an opinion or action to be rational, one must first provide a formal characterization of the rationality of those opinions or actions. What is to count as a rational ground can only be explained by formal procedures and results achievable via those procedures. To be more specific, I claim that the process of opinion formation and practical reflection is subject to rational justification based on internalist rules. The rules governing theoretical rationality can have their content transformed in a further move, if one takes the result of the process of rational opinion-formation as the product of an epistemological determination, that is, as a decision about which opinion to hold that is made on the basis of epistemological or prudential goals. Implicit in this position is the controversial idea that one can actually decide to believe something. The rules of practical reason are the rules that guide the rational selection of objectives and actions. The structural parallelism of theoretical and practical rationality consists, therefore, in the fact that both refer to mental processes that are controlled by rules which one freely accepts and follows. In both cases, these rules are to be understood as governing the rational choice of a mental or physical action. c) Therefore, the question of whether rationality—being rational—can in turn be grounded by reasons can be answered in the following way: The rules of rationality can only be justified with reference to a person’s goals, as the best strategy for achieving those goals. If someone does not desire the optimal realization of his goals, there is no other way of arguing directly for rationality. One can only attempt to demonstrate—if the person is open to argument—that it is typically in the person's own best interest to adhere to the rules of rationality. (shrink)

My project is to reconsider the Kantian conception of practical reason. Some Kantians think that practical reasoning must be more active than theoretical reasoning, on the putative grounds that such reasoning need not contend with what is there anyway, independently of its exercise. Behind that claim stands the thesis that practical reason is essentially efficacious. I accept the efficacy principle, but deny that it underwrites this inference about practical reason. My inquiry takes (...) place against the background of recent Kantian metaethical debate — each side of which, I argue, correctly points to issues that need to be jointly accommodated in the Kantian account of practical reason. The constructivist points to the essential efficacy of practical reason, while the realist claims that any genuinely cognitive exercise of practical reason owes allegiance to what is there anyway, independently of its exercise. I argue that a Kantian account of respect for persons (“recognition respect”) suggests how the two claims might be jointly accommodated. The result is an empirical moral realism that is itself neutral on the received Kantian metaethical debate. (shrink)

This study aims to develop and defend an account of practical rationality and intention that explains how weakness of the will is conceptually possible. I first present two sceptical arguments against the possibility of weakness and then distinguish two different responses to scepticism that defends its possibility. Both sceptical arguments are motivated by what many have believed is an analogy between theoretical and practical reasoning. This analogy holds that the conclusion of practical reasoning is an intention (...) just as the conclusion of theoretical reasoning is a belief. The particular version held by what I call the Socratic theorists claims, in addition, that the value of desirability is transferred from premisses to conclusion in practical reasoning, just as probability is transferred from premisses to conclusion in theoretical reasoning. One example of an author who takes the analogy as a basic premise and seek to explain how weakness of the will still may be possible, is Donald Davidson. Critics of Davidson object that the the kinds of difficulties that his account runs into shows that the Socratic version of the analogy must be false; not only is this account phenomenologically implausible, it also exaggerates the degree of irrationality of the weak agent. In this study I suggest the possibility of a weaker version of the Davidsonian account. The main source of difficulty for the Davidsonian account, I argue, may not be its reliance on the Socratic version of the analogy between practical and theoretical reasoning, but rather its particular understanding of this analogy in terms of an analogy between practical and inductive-statistical reasoning. This understanding may lead one to accept too “rationalistic” a picture of the reasoning processes behind weakness of the will which, in effect, may make the account vulnerable to objections that it is phenomenologically implausible and exaggerates the irrationality of the weak agent. The weaker version of the Davidsonian account that I propose, ties in the account of weakness with the notions of “satisficing” and “default reasoning”. Although it preserves the central idea of the stronger version that intentions are unconditional evaluative judgements, it proposes a different view of the contents of these judgements, as well as of the reasoning process that lie behind them. It is not difficult to motivate this weaker view: given our human finitary predicament, both satisficing and default reasoning seem to be likely results of an optimal trade-off between the speed and reliability of our computational processes. The question is how these notions may shape the concepts we use to understand weakness of the will. I argue that if we modify the account usually ascribed to Davidson in the light of these notions, the result is a less rationalistic picture of weakness of the will. The gains are more phenomenological credibility as well as a less extreme view of the degree of irrationality involved. (shrink)

KANT ARGUES AT GREAT LENGTH in the Critique of Pure Reason that the existence of God cannot be demonstrated by means of theoretical reason. For after dividing all traditional theistic proofs into three different kinds—the ontological, the cosmological, and the physico-theological—Kant argues first that the cosmological and physico-theological implicitly assume the ontological argument and then that the ontological argument is necessarily fallacious. By restricting knowledge in this manner Kant notoriously makes room for faith, that is, in this (...) case, for a practical proof of the existence of God, which he develops in the Critique of Practical Reason. Kant’s reasons for rejecting theoretical proofs of the existence of God have received considerable attention. In particular, Kant’s objection to the ontological argument, namely that existence is not a real predicate, still seems relevant in contemporary philosophy of religion. What has not received much attention, however, is the relationship between Kant’s rejection of theistic proofs in his critical period and his views on the matter in his pre-critical period. For throughout his pre-critical period, but especially in his The Only Possible Argument in Support of a Demonstration of the Existence of God, Kant believes that there is a theoretical proof of the existence of God. One would naturally expect Kant’s criticisms of theistic proofs as developed in the “ideal of pure reason” to apply in straightforward ways to his earlier attempts at a theistic proof. However, Kant rejects the three traditional arguments in The Only Possible Argument just as he does in the first Critique. Further, his reason for rejecting the ontological argument in particular is identical to the one presented in the first Critique: “Existence is not a predicate or a determination of a thing.” Accordingly, Kant understood himself to be developing a theistic proof in The Only Possible Argument that is distinct from the three traditional arguments and is also not subject to the objections he raises against them. Given that Kant rejects all theoretical proofs of God’s existence in his critical period and given that he did not take his critical objections to the traditional proofs to apply to the theistic proof developed in The Only Possible Argument, what is his justification for rejecting his pre-critical argument for God’s existence?

A long debate in aesthetics concerns the reasoned nature of criticism. The main questions in the debate are whether criticism is based on (normative) reasons, whether critics communicate reasons for their audience’s responses, and if so, how to understand these critical reasons. I argue that a great obstacle to making any progress in this debate is the deeply engrained assumption, shared by all sides of the debate, that reasons can only be either theoretical reasons (i.e., those that explain what (...) to believe or what propositions are true) or practical reasons (i.e., those that explain what is to be done or what actions are good/required/called for/otherwise worthy of doing). My aims are (1) to put pressure on this assumption that, if there are critical reasons, they must be either theoretical or practical (the EITHER/OR assumption), and (2) to suggest that, if there are critical reasons, the most central among them are neither theoretical nor practical (NEITHER/NOR).

Resumo. Neste artigo apontaremos a filosofia kantiana como um sistema que tem como preocupação fundamental o a priori. Isto envolve tanto a razão teórica quanto a razão prática. Esta, por sua vez, dividida em ética e direito. Palavras-chave. Kant, razão teórica, razão prática, ética e direito, a priori.: In this article we will identify the Kantian philosophy as a system, whose fundamental concern a priori. This involves both theoretical reason and practical reason. This, in turn, divided (...) into ethics and law. Keywords. Kant, theoretical reason, practical reason, ethics and law, a priori. (shrink)

In his reading of Kant’s moral philosophy and its grounding in freedom of the will, Allison is best know for giving an exclusively “practical” reading to doctrines about noumenal agency, so that they are taken to have none of the outlandish metaphysical implications often thought to be associated with the Kantian conception of freedom. The central feature of Allison’s interpretation is that Kant operates with a theory of agency in which, from the agent’s standpoint, reasons do not act as (...) causes, but operate only insofar as they are taken up by the agent into principles or “maxims.” According to this “Incorporation Thesis,” sensuous impulses or desires are not causes of an action. So there is no reason to regard the motive of duty as a “noumenal” cause competing with sensuous or “phenomenal” causes. Instead, Kant’s “two standpoints theory” is to be understood as distinguishing the action as viewed from the agent’s practical standpoint from causal conceptions governing the theoretical standpoint.

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.

Contrary to Karl Leonhard Reinhold's theoretical critique of Kant's philosophy, his practical critique has been almost unknown. In my paper, I shall reconstruct Reinhold's practical philosophy after Kant. I will concentrate on the so‐called Reinhold's dilemma, which concerns the problem of moral imputability in the case of immoral actions in Kant. Also, I shall explain how Reinhold tried to escape this dilemma by introducing a new action theory and by sharply distinguishing between reason and will. Finally, (...) I shall evaluate Reinhold's practical significance by relating his conception of individual freedom to recent theories of volitional self‐determination. (shrink)

ABSTRACT A long debate in aesthetics concerns the reasoned nature of criticism. The main questions in the debate ask whether criticism is based on reasons, whether critics communicate reasons for their audience’s responses, and, if so, how to understand these critical reasons. I argue that a great obstacle to making any progress in this debate is the deeply engrained assumption, shared by all sides of the debate, that reasons can only be either theoretical reasons or practical reasons. My (...) aims are to put pressure on this assumption that, if there are critical reasons, they must be either theoretical or practical, and to suggest that, if there are critical reasons, the most central among them are neither theoretical nor practical.

This thesis justifies the need for and develops a new integrated model of practical reasoning and argumentation. After framing the work in terms of what is reasonable rather than what is rational (chapter 1), I apply the model for practical argumentation analysis and evaluation provided by Fairclough and Fairclough (2012) to a paradigm case of unreasonable individual practical argumentation provided by mass murderer Anders Behring Breivik (chapter 2). The application shows that by following the model, Breivik is (...) relatively easily able to conclude that his reasoning to mass murder is reasonable – which is understood to be an unacceptable result. Causes for the model to allow such a conclusion are identified as conceptual confusions ingrained in the model, a tension in how values function within the model, and a lack of creativity from Breivik. Distinguishing between dialectical and dialogical, reasoning and argumentation, for individual and multiple participants, chapter 3 addresses these conceptual confusions and helps lay the foundation for the design of a new integrated model for practical reasoning and argumentation (chapter 4). After laying out the theoretical aspects of the new model, it is then used to re-test Breivik’s reasoning in light of a developed discussion regarding the motivation for the new place and role of moral considerations (chapter 5). The application of the new model shows ways that Breivik could have been able to conclude that his practical argumentation was unreasonable and is thus argued to have improved upon the Fairclough and Fairclough model. It is acknowledged, however, that since the model cannot guarantee a reasonable conclusion, improving the critical creative capacity of the individual using it is also of paramount importance (chapter 6). The thesis concludes by discussing the contemporary importance of improving practical reasoning and by pointing to areas for further research (chapter 7). (shrink)
