This work identifies Kant’s doctrine of inner sense as a central element within the ‘architectonic of pure reason’ of the first Critique, exposes its variant construals, and considers the implications of its problematicity for Kant’s theoretical philosophy most generally.

I begin by refuting Davidson’s classic account of akrasia, which turns on a purported distinction between judging p and judging p “all things considered.” The upshot of this refutation is that an adequate account of akrasia must turn on a distinction between different ways in which the agent can make judgments about her practical reasons. On the account I propose, an akratic agent makes an existential judgment that there is some decisive practical reason to act in a certain way (...) without also knowing what that reason is. An agent can do what such a reason requires only by deviating from the conditions under which her action would be a response to it. The possibility of akrasia is a consequence of our concern not only to perform actions that match what our reasons require but also to manifest reasons in conduct that they inform. (shrink)

The lever appears to be a very simple object, a tool used since ancient times for the most primitive of tasks: to lift and to balance. Why, then, were prominent intellectuals active around 1800 in areas as diverse as science, philosophy, and literature inspired to think and write about levers? In The Lever as Instrument of Reason, readers will discover the remarkable ways in which the lever is used to model the construction of knowledge and to mobilize new ideas (...) among diverse disciplines. These acts of construction are shown to model key aspects of the human, from the more abstract processes of moral decision-making to a quite literal equation of the powerful human ego with the supposed stability and power of the fulcrum point.

This paper challenges the first Gettier counterexample to the tripartite account of knowledge. Noting that 'the man who will get the job' is a description and invoking Donnellan's distinction between their 'referential' and 'attributive' uses, I argue that Smith does not actually believe that the man who will get the job has ten coins in his pocket. Smith's ignorance about who will get the job shows that the belief cannot be understood referentially, his ignorance of the coins in his (...) pocket shows that it cannot be understood attributively. An explanation for why Smith appeared to have justified true belief is given by distinguishing between 'belief' and 'belief in truth'. Smith believes the sentence 'the man who will get the job has ten coins in his pocket' to be true (he mistakenly believes that Jones will get the job, of whom he knows that he has ten coins in his pocket) (hence his 'belief'), the sentence is true (hence 'truth'), and he has sufficient reason to assent to it (hence his 'justification'). But he does not believe the proposition expressed. Hence he does not know it either. (shrink)

Each of Kant’s three Critiques offers an account of the nature of a mental faculty and arrives at this account by means of a procedure I call ‘faculty analysis’. Faculty analysis is often regarded as among the least defensible aspects of Kant’s position; as a consequence, philosophers seeking to inherit Kantian ideas tend to transpose them into a different methodological context. I argue that this is a mistake: in fact faculty analysis is a live option for philosophical inquiry today. My (...) argument is as follows: Faculty analysis is a live option for certain kinds of philosophical theories if so-called “agentialist” views about the nature of belief are correct. There are good reasons for thinking that such views are correct. So faculty analysis should not be dismissed out of hand. Since the first premise in this argument bears a lot of weight, a large part of the paper is devoted to clarifying and defending it, in part by arguing that Kant himself holds a version of agentialism about belief.

This sharply intelligent, consistently provocative book takes the reader on an astonishing, thought-provoking voyage into the realm of delightful uncertainty--a world of paradox in which logical argument leads to contradiction and common sense is seemingly rendered irrelevant.

My book 'History of Rationalities: Ways of Thinking from Vico to Hacking and Beyond' draws a number of philosophical implications from Hacking's characterization of the notion of style and analyzes them. How did certain concepts emerge and change? How have our styles of reasoning changed and why? To what extent is the emergence of the styles of reasoning at a certain point of history a contingent circumstance? Why have these styles of reasoning endured? In this article I explain how I (...) have attempted to answer these questions in my book. (shrink)

I address a type of circularity threat that arises for the view that we employ general basic logical principles in deductive reasoning. This type of threat has been used to argue that whatever knowing such principles is, it cannot be a fully cognitive or propositional state, otherwise deductive reasoning would not be possible. I look at two versions of the circularity threat and answer them in a way that both challenges the view that we need to apply general logical principles (...) in deductive reasoning and defuses the threat to a cognitivist account of knowing basic logical principles.

The ArgumentMany of the epistemological issues that occupied natural philosophers of the seventeenth century were expressed visually in title-page engravings. One of those issues concerned the relative status to be accorded to evidence of the senses, as compared to knowledge gained by faith or reason. In title-page illustrations, the various arguments were often waged by a series of light metaphors: the Light of Reason, the Light of Nature, and the Lights of Sense, Scripture, and Grace. When such illustrations are (...) examined with the authors' theological views in mind, it becomes apparent that in the first half of the seventeenth century, Catholic authors favored the Light of Reason as a source of truth, while Protestant authors favored the Light of Nature. Since by the end of the century it was widely accepted by scientists of all religious persuasions that certain knowledge must be grounded in sense evidence and the direct study of nature, one might argue that in this instance Protestantism was responsible for nurturing an important development of the Scientific Revolution. However, the skewed nature of the sample and the large number of counterexamples available mitigate against taking this offshoot of the Merton thesis too seriously. (shrink)

When we experience the world – see, hear, feel, taste, or smell things – we gain all sorts of knowledge about the things around us. And this knowledge figures heavily in our reasoning about the world – about what to think and do in response to it. But what is the nature of this knowledge? On one commonly held view, all knowledge is constituted by beliefs in propositions. But in this paper I argue against this view. (...) I argue that some knowledge is constituted, not by beliefs in propositions, but by awareness of properties and objects. To make my case, I focus on the role of visual perception in reasoning. I start by introducing a principle about the relationship between knowledge and reasoning, which says that to learn something new by reasoning, one must know the bases of one’s reasoning. Then I argue that in some cases of genuine, knowledge-conferring reasoning, the bases of our reasoning are not propositions that we believe; rather, they’re properties or objects that we see. Thus, I conclude that some such knowledge is non-propositional and is rather what some call “knowledge of things”. (shrink)

The eminent philosopher Keith Lehrer offers an original and distinctively personal view of central aspects of the human condition, such as reason, knowledge, wisdom, autonomy, love, consensus, and consciousness. He argues that what is uniquely human is our capacity for evaluating our own mental states (such as beliefs and desires), and suggests that we have a system for such evaluation which allows the resolution of personal and interpersonal conflict. The keystone in this system is self-trust, on which reason, (...) class='Hi'>knowledge, and wisdom are grounded. (shrink)

Williamson has argued against scepticism concerning our metaphysically modal knowledge, by arguing that standard patterns of suppositional reasoning to counterfactual conclusions provide reliable sources of correct ascriptions of possibility and necessity. The paper argues that, while Williamson’s claims relating to necessity may well be right, he has not provided adequate reasons for thinking that the familiar modes of counterfactual reasoning to which he points generalise to provide a decent route to ascriptions of possibility. The paper also explores another (...) path to ascriptions of possibility that may be extracted from Williamson’s ideas, before briefly considering the general status of counterfactual reasoning in relation to our knowledge of possibilities.

The debate on the possibility of attaining metaphysical knowledge by the method of reasoning began with the ancient Greek philosophers and continues to this day. This article aims to examine how Râzî argues for the possibility of attaining metaphysical knowledge through the method of reasoning. He first argues that existence has two parts, the sensed and the thought, in order to demonstrate that metaphysical knowledge can be obtained through the method of reasoning. Then he tries to prove (...) that existence is not limited to the material. After presenting evidence for the existence of things other than the sensible in existence that can be perceived with the intellect, he tries to discuss our devices to relate to this sphere of existence in a comparative manner. In this comparison, two possible devices for attaining metaphysical knowledge emerge: the theoretical intellect and the purified soul. After revealing the positive and negative aspects of both in this comparison, he argues that the most reliable device is the theoretical intellect and the technique is the method of reasoning Râzî gives various answers to those who object to the possibility of obtaining metaphysical knowledge through the method of reasoning. Râzî tries to put forward the grounds on which the groups who object to the method of reasoning are based. He then evaluates their justifications in terms of accuracy and consistency. Thus, he tests both the relevance of each group's objection to the subject and its consistency with the group's other beliefs. He then presents the justifications for his own opinion on the method of reasoning and the consistency of this method with his other beliefs. Following this method, Râzî first divides those who object to the method of reasoning into two categories according to whether or not they accept a metaphysical sphere of existence. According to this division, those who object to the method because they do not accept a metaphysical sphere of existence are the Sophists, Sumeniyya, Mujasimah, Dhahriyya, and Hashawiyya. Although this group does not accept a metaphysical sphere of existence, they are divided into two classes: those who believe in God and those who do not. According to Râzî, the group that accepts the metaphysical sphere of existence but objects to the method of reasoning is the Talimiyya. They claim that metaphysical knowledge can only be attained through the teaching of an innocent instructor, not by the method of reasoning. The different approaches of these groups are the reason why Râzî sometimes emphasizes accuracy, sometimes consistency, and sometimes proving the metaphysical domain of existence in his answers to those who object to the method of reasoning.

The papers collected in this volume exemplify some of the trends in current approaches to logic, language and computation. Written by authors with varied academic backgrounds, the contributions are intended for an interdisciplinary audience. The first part of this volume addresses issues relevant for multi-agent systems: reasoning with incomplete information, reasoning about knowledge and beliefs, and reasoning about games. Proofs as formal objects form the subject of Part II. Topics covered include: contributions on logical frameworks, linear logic, and different (...) approaches to formalized reasoning. Part III focuses on representations and formal methods in linguistic theory, addressing the areas of comparative and temporal expressions, modal subordination, and compositionality. (shrink)

By tracing a specific development through the approaches of Peirce, James, and Dewey I present a view of (classical) pragmatist epistemology that invites comparison with recent work in feminist epistemology. Important dimensions of pragmatism and feminism emerge from this critical dialectical relationship between them. Pragmatist reflections on the role of reason and philosophy in a changing world encourage us to see that philosophy's most creative and most responsible future must also be a feminist one.

The paper gives an interpretation of Kant's doctrine of the fact of reason against the background of a constructivist reading of his philosophy, which does not allow us to appeal to any indubitable facts. The fact of reason is the object of a philosophical account of the moral law forms the quid juris part of deduction or legitimization of the law. A more intuitive grasp of the fact is the phenomenon of reverence for duty which ordinary people grasp in form (...) of a feeling and emotion. (shrink)

Is knowledge necessary or sufficient or both necessary and sufficient for acceptable practical reasoning and rational action? Several authors (e.g., Williamson, Hawthorne, and Stanley) have recently argued that the answer to these questions is positive. In this paper I present several objections against this view (both in its basic form as well in more developed forms). I also offer a sketch of an alternative view: What matters for the acceptability of practical reasoning in at least many cases (and in (...) all the cases discussed by the defenders of a strong link between knowledge and practical reasoning) is not so much knowledge but expected utility.

Genevieve Lloyd’s Spinoza is quite a different thinker from the arch rationalist caricature of some undergraduate philosophy courses devoted to “The Continental Rationalists”. Lloyd’s Spinoza does not see reason as a complete source of knowledge, nor is deductive rational thought productive of the highest grade of knowledge. Instead, that honour goes to a third kind of knowledge—intuitive knowledge (scientia intuitiva), which provides an immediate, non-discursive knowledge of its singular object. To the embarrassment of some hard-nosed (...) philosophers, intellectual intuition has an affective component; it is a form of love, and ultimately given that human beings are finite modes of God/Nature (Deus sive Natura), it is a form of the intellectual love of God (amor Dei intellectualis). Some philosophers do not know what to make of this mysterious aspect of Spinoza’s philosophy, which is nonetheless firmly anchored in a reading of Part V of the Ethics. Nonetheless, this note will insist with Lloyd’s “Reconsidering Spinoza’s Rationalism” that such doctrine is an integral part of Spinoza’s philosophy. Moreover, it will be shown that Spinoza is well aware of the limitations of reason (ratio) in gaining scientific knowledge of the world and requires intuition precisely because of the inability of reason to represent individuals in their full particularity. Imagination too has a role to play in shaping scientific knowledge, although reason performs a vital critical role in disciplining and liberating the human mind from inadequate imaginary ideas. The result is an interpretation of Spinoza’s epistemology as both rationalist and intuitionist. DOI: 10.1080/24740500.2021.1962652. (shrink)

This paper develops a novel, functionalist, unified account of the epistemic normativity of reasoning. On this view, epistemic norms drop out of epistemic functions. I argue that practical reasoning serves a prudential function of generating prudentially permissible action, and the epistemic function of generating knowledge of what one ought to do. This picture, if right, goes a long way towards normatively divorcing action and practical reasoning. At the same time, it unifies reasoning epistemically: practical and theoretical reasoning will turn (...) out to be governed by the same epistemic norm—knowledge—in virtue of serving the same epistemic function: generating knowledge of the conclusion.

Kant advertises his Critique of Pure Reason as fulfilling reason's "most difficult" task: self-knowledge. As it is carried out in the Critique, this investigation is meant to be "scientific and fully illuminating"; for Kant, this means that it must follow a proper method. Commentators writing in English have tended to dismiss Kant's claim that the Critique is the scientific expression of reason's self-knowledge---either taking it to be sheer rhetoric, or worrying that it pollutes the Critique with an unfortunate (...) residue of rationalism. As a result, there is little sustained treatment of the method of the Critique in the secondary literature. Since Kant holds that the substantive insights of critical philosophy are not separable from the methodological context in which they come to light, this is a serious mistake. My dissertation corrects for this, by approaching the Critique through an examination of its method. In doing so, it yields a reading of the Transcendental Deduction that not only promises to resolve current debates about its "proof structure", but also fully accounts for the Deduction's pivotal role in the work as a whole.

The notion of relevance plays a role in many accounts of knowledge and knowledge ascription. Although use of the notion is well-motivated, theorists struggle to codify relevance. A reasonable person standard of relevance addresses this codification problem, and provides an objective and flexible standard of relevance; however, treating relevance as reasonableness seems to allow practical factors to determine whether one has knowledge or not—so-called “pragmatic encroachment.” I argue that a fuller understanding of reasonableness and of the role (...) of practical factors in the acquisition of knowledge lets us avoid pragmatic encroachment.

This paper maintains that empathy with fictional characters, aka fictional empathy, is morally valuable insofar as it can provide the empathizer with knowledge of values. More precisely, the paper argues that fictional empathy enables the empathizer to become imaginatively acquainted with the other’s values, even if these values are very different from one’s own. After motivating the topic in the introduction (section 1), the paper presents some thoughts about the epistemology of value and empathy, establishing a distinction between direct (...) and imaginative acquaintance with values (section 2). Next, it argues that empathy can lead the empathizer to co-experience the other’s values and, in so doing, make her directly or imaginatively acquainted with them (section 3). The paper discusses a possible challenge concerning the epistemic function of the imagination and explores different ways in which we can become imaginatively acquainted with values (section 4). It then examines features of fiction that explain why fictional empathy might be better suited than empathy for real others in pursuing this task (section 5). The paper closes by providing some reasons why we should regard the imaginative acquaintance with value attained through fictional empathy as morally valuable (section 6). (shrink)

If proofs are nothing more than truth makers, then there is no force in the standard argument against classical logic (there is no guarantee that there is either a proof forA or a proof fornot A). The standard intuitionistic conception of a mathematical proof is stronger: there are epistemic constraints on proofs. But the idea that proofs must be recognizable as such by us, with our actual capacities, is incompatible with the standard intuitionistic explanations of the meanings of the logical (...) constants. Proofs are to be recognizable in principle, not necessarily in practice, as shown in section 1. Section 2 considers unknowable propositions of the kind involved in Fitch''s paradox:p and it will never be known thatp. It is argued that the intuitionist faces a dilemma: give up strongly entrenched common sense intuitions about such unknowable propositions, or give up verificationism. The third section considers one attempt to save intuitionism while partly giving up verificationism: keep the idea that a proposition is true iff there is a proof (verification) of it, and reject the idea that proofs must be recognizable in principle. It is argued that this move will have the effect that some standard reasons against classical semantics will be effective also against intuitionism. This is the case with Dummett''s meaning theoretical argument. At the same time the basic reason for regarding proofs as more than mere truth makers is lost. (shrink)

In this essay I analyse Kant’s view on the regulative role of reason, and in particular on what he describes as the ‘indispensably necessary’ role of ideas qua foci imaginarii in the Appendix. I review two influential readings of what has become known as the ‘transcendental illusion’ and I offer a novel reading that builds on some of the insights of these earlier readings. I argue that ideas of reason act as imaginary standpoints, which are indispensably necessary for scientific (...) class='Hi'>knowledge by making inter-conversational agreement possible. Thus, I characterise scientific knowledge as a distinctive kind of perspectival knowledge. This novel reading can illuminate the role of reason in complementing the faculty of understanding and sheds light on the apparent dichotomy between the first and the second part of the Appendix. More to the point, this novel reading takes us right to the heart of what scientific knowledge is, according to Kant, and how it differs from bogus knowledge and opinion. (shrink)

Many books explain what is known about the universe. This book investigates what cannot be known. Rather than exploring the amazing facts that science, mathematics, and reason have revealed to us, this work studies what science, mathematics, and reason tell us cannot be revealed. In The Outer Limits of Reason, Noson Yanofsky considers what cannot be predicted, described, or known, and what will never be understood. He discusses the limitations of computers, physics, logic, and our own thought processes. Yanofsky describes (...) simple tasks that would take computers trillions of centuries to complete and other problems that computers can never solve; perfectly formed English sentences that make no sense; different levels of infinity; the bizarre world of the quantum; the relevance of relativity theory; the causes of chaos theory; math problems that cannot be solved by normal means; and statements that are true but cannot be proven. He explains the limitations of our intuitions about the world -- our ideas about space, time, and motion, and the complex relationship between the knower and the known. Moving from the concrete to the abstract, from problems of everyday language to straightforward philosophical questions to the formalities of physics and mathematics, Yanofsky demonstrates a myriad of unsolvable problems and paradoxes. Exploring the various limitations of our knowledge, he shows that many of these limitations have a similar pattern and that by investigating these patterns, we can better understand the structure and limitations of reason itself. Yanofsky even attempts to look beyond the borders of reason to see what, if anything, is out there. (shrink)

The purpose of this paper is to explain how infinitism—the view that reasons are endless and non-repeating—solves the epistemic regress problem and to defend that solution against some objections. The first step is to explain what the epistemic regress problem is and, equally important, what it is not. Second, I will discuss the foundationalist and coherentist responses to the regress problem and offer some reasons for thinking that neither response can solve the problem, no matter how they are (...) tweaked. Then, I want to present the infinitist solution to the problem and defend it against some of the well known objections to it. (shrink)

The epistemology of modality has focused on metaphysical modality and, more recently, counterfactual conditionals. Knowledge of kinds of modality that are not metaphysical has so far gone largely unexplored. Yet other theoretically interesting kinds of modality, such as nomic, practical, and ‘easy’ possibility, are no less puzzling epistemologically. Could Clinton easily have won the 2016 presidential election—was it an easy possibility? Given that she didn’t in fact win the election, how, if at all, can we know whether she easily (...) could have? This paper investigates the epistemology of the broad category of ‘objective’ modality, of which metaphysical modality is a special, limiting case. It argues that the same cognitive mechanisms that are capable of producing knowledge of metaphysical modality are also capable of producing knowledge of all other objective modalities. This conclusion can be used to explain the roles of counterfactual reasoning and the imagination in the epistemology of objective modality. (shrink)
