The complex sensation of vision begins with the relatively simple photoisomerization of the visual pigment chromophore 11-cis-retinal to its all-trans configuration. This event initiates a series of biochemical reactions that are collectively referred to as phototransduction, which ultimately lead to a change in the electrochemical signaling of the photoreceptor cell. To operate in a wide range of light intensities, however, the phototransduction pathway must allow for adjustments to background light. These take place through physiological adaptation processes that rely primarily on (...) Ca2+ ions. While Ca2+ may modulate some activities directly, it is more often the case that Ca2+-binding proteins mediate between transient changes in the concentration of Ca2+ and the adaptation processes that are associated with phototransduction. Recently, combined genetic, physiological, and biochemical analyses have yielded new insights about the properties and functions of many phototransduction-specific components, including some novel Ca2+-binding proteins. Understanding these Ca2+-binding proteins will provide a more complete picture of visual transduction, including the mechanisms associated with adaptation, and of related degenerative diseases.

The value problem in epistemology is rooted in a commonsense intuition to the effect that knowledge is more valuable than true belief. Call this the “guiding intuition.” The guiding intuition generates a problem in light of two additional considerations. The first is that knowledge is (roughly) justified or warranted true belief.[1] The second is that on certain popular accounts of justification or warrant (e.g. reliabilism), its value is apparently instrumental to and hence derivative from the value of true belief.[2] But (...) if knowledge is justified true belief and the value of justification is derivative from that of true belief, how is it that knowledge is more valuable than true belief?

Rational agents are supposed to maximize expected utility. But what are the options from which they choose? I outline some constraints on an adequate representation of an agent’s options. The options should, for example, contain no information of which the agent is unsure. But they should be sufficiently rich to distinguish all available acts from one another. These demands often come into conflict, so that there seems to be no adequate representation of the options at all. After reviewing existing proposals (...) for how to construe decision-theoretic options and finding them all wanting, I suggest that our model of rational agents should include a special domain of ‘virtual’ option propositions to serve as formal objects of deliberation and choice.

Standard characterizations of virtue epistemology divide the field into two camps: virtue reliabilism and virtue responsibilism. Virtue reliabilists think of intellectual virtues as reliable cognitive faculties or abilities, while virtue responsibilists conceive of them as good intellectual character traits. I argue that responsibilist character virtues sometimes satisfy the conditions of a reliabilist conception of intellectual virtue, and that consequently virtue reliabilists, and reliabilists in general, must pay closer attention to matters of intellectual character. This leads to several new questions and (...) (...) challenges for any reliabilist epistemology. (shrink)

While Okin's feminist appropriation of Rawls's theory of justice requires that principles of justice be applied directly to the family, Rawls seems to require only that the family be minimally just. Rawls's recent proposal dulls the critical edge of liberalism by capitulating too much to those holding sexist doctrines. Okin's proposal, however, is insufficiently flexible. An alternative account of the relation of the political and the nonpolitical is offered by Jürgen Habermas.

I examine here whether reliability is a defining feature of (moral or intellectual) virtues. I argue (1) that reliability is not a defining feature of a virtue where virtues are conceived (as they often are) as “personal excellences,” but (2) that there is another (also intuitive and familiar) conception of a virtue according to which reliability is a defining feature. I also argue (3) that even on the former conception, a certain rational belief pertaining to reliability is essential and (4) (...) that reliability itself, while not a defining feature of a virtue thus conceived, nevertheless is a concomitant of it.

What is intellectual humility? In this essay, we aim to answer this question by assessing several contemporary accounts of intellectual humility, developing our own account, offering two reasons for our account, and meeting two objections and solving one puzzle.

After a brief overview of what intellectual virtues are, I offer three arguments for the claim that education should aim at fostering ‘intellectual character virtues’ like curiosity, open-mindedness, intellectual courage, and intellectual honesty. I then go on to discuss several pedagogical and related strategies for achieving this aim.

With its focus on intellectual virtues and their role in the acquisition and transmission of knowledge and related epistemic goods, virtue epistemology provides a rich set of tools for educational theory and practice. In particular, characteristics under the rubric of "responsibilist" virtue epistemology, like curiosity, open-mindedness, attentiveness, intellectual courage, and intellectual tenacity, can help educators and students define and attain certain worthy but nebulous educational goals like a love of learning, lifelong learning, and critical thinking. This volume is devoted to (...) exploring the intersection between virtue epistemology and education. It assembles leading virtue epistemologists and philosophers of education to address such questions as: Which virtues are most essential to education? How exactly should these virtues be understood? How is the goal of intellectual character growth related to other educational goals, for example, to critical thinking and knowledge-acquisition? What are the "best practices" for achieving this goal? Can growth in intellectual virtues be measured? The chapters are a prime example of "applied epistemology" and promise to be a seminal contribution to an area of research that is rapidly gaining attention within epistemology and beyond. (shrink)

ABSTRACT This paper considers the four ways that the concept of ‘irrationality’ has been employed by members of the European peace movement in their evaluation of current bloc tensions. Against Bernard Williams who has recently taken issue with the peace movement's alleged tendency to dismiss political realities, the present author argues that the use of the language of irrationality reveals just the opposite orientation. Finally, it is argued that although the language of irrationality constitutes a powerful descriptive and normative instrument, (...) as an explanation of the Cold War it is a nonstarter. (shrink)

Open-mindedness enjoys widespread recognition as an intellectual virtue. This is evident, among other ways, in its appearance on nearly every list of intellectual virtues in the virtue epistemology literature.1 Despite its popularity, however, it is far from clear what exactly open-mindedness amounts to: that is, what sort of intellectual orientation or activity is essential to it. In fact, there are ways of thinking about open-mindedness that cast serious doubt on its status as an intellectual virtue. Consider the following description, from (...)

The terrain of character-based or “responsibilist” virtue epistemology has evolved dramatically over the last decade -- so much so that it is far from clear what, if anything, unifies the various views put forth in this area. In an attempt to bring some clarity to the overall thrust and structure of this movement, I develop a fourfold classification of character-based virtue epistemologies. I also offer a qualified assessmentof each approach, defending a certain account of the probable future of this burgeoning (...) subfield. (shrink)

Evidentialists maintain that epistemic justification is strictly a function of the evidence one has at the moment of belief. I argue here, on the basis of two kinds of cases, that the possession of good evidence is an insuflicient basis for justification. I go on to propose a modification of evidentialism according to which justification sometimes requires intellectually virtuous agency. The discussion thereby underscores an important point of contact between evidentialism and the more recent enterprise of virtue epistemology.

This paper examines the claim made by certain virtue epistemologists that intellectual character virtues like fair-mindedness, open-mindedness and intellectual courage merit an important and fundamental role in epistemology. I begin by considering whether these traits merit an important role in the analysis of knowledge. I argue that they do not and that in fact they are unlikely to be of much relevance to any of the traditional problems in epistemology. This presents a serious challenge for virtue epistemology. I go on (...) to examine the work of two other virtue epistemologists in light of this challenge and then sketch an alternative approach that reveals how the intellectual virtues might merit a substantial role in epistemology even if not a role in connection with more traditional epistemological projects.

This book has grown out of eight years of close collaboration among its authors. From the very beginning we decided that its content should come out as the result of a truly common effort. That is, we did not "distribute" parts of the text planned to each one of us. On the contrary, we made a point that each single paragraph be the product of a common reflection. Genuine team-work is not as usual in philosophy as it is in other (...) academic disciplines. We think, however, that this is more due to the idiosyncrasy of philosophers than to the nature of their subject. Close collaboration with positive results is as rewarding as anything can be, but it may also prove to be quite difficult to implement. In our case, part of the difficulties came from purely geographic separation. This caused unsuspected delays in coordinating the work. But more than this, as time passed, the accumulation of particular results and ideas outran our ability to fit them into an organic unity. Different styles of exposition, different ways of formalization, different levels of complexity were simultaneously present in a voluminous manuscript that had become completely unmanageable. In particular, a portion of the text had been conceived in the language of category theory and employed ideas of a rather abstract nature, while another part was expounded in the more conventional set-theoretic style, stressing intui tivity and concreteness.

Abstract: Against the background of a great deal of structural symmetry between intellectual and moral virtue and vice, it is a surprising fact that what is arguably the central or paradigm moral vice—that is, moral malevolence or malevolence proper—has no obvious or well-known counterpart among the intellectual vices. The notion of "epistemic malevolence" makes no appearance on any standard list of intellectual vices; nor is it central to our ordinary ways of thinking about intellectual vice. In this essay, I argue (...) that there is such a thing as epistemic malevolence and offer an account of its basic character and structure. Doing so requires a good deal of attention to malevolence simpliciter . In the final section of the essay, I offer an explanation of our relative unfamiliarity with this trait. (shrink)

One alleged advantage of credit theories of knowledge is that they are capable of explaining why knowledge is essentially more valuable than mere true belief. I argue that credit theories in fact provide grounds for denying this claim and therefore are incapable of overcoming the ‘value problem’ in epistemology. Much of the discussion revolves around the question of whether true belief is always epistemically valuable. I also consider to what extent, if any, my main argument should worry credit theorists.

__Deep in Thought_ provides an introduction to intellectual virtues—the personal qualities and character strengths of good thinkers and learners—and outlines a pragmatic approach for teachers to reinforce them in the classroom._ With a combination of theoretical expertise and practical experience, philosopher Jason Baehr endorses intellectual virtues as a rich, meaningful way to think about and understand the purpose of education. He makes a persuasive case for prioritizing intellectual virtues in the classroom to facilitate deeper learning, encourage lifelong learning, and (...) enrich teacher practice. Baehr profiles nine key virtues that enable learners to initiate the process of learning, maintain forward momentum, and overcome common obstacles. With engaging anecdotes and concrete examples, he presents a wealth of principles, postures, and practices that educators can employ in promoting essential habits of mind such as curiosity, open-mindedness, and intellectual courage. Baehr illustrates how opportunities to practice these intellectual habits can be integrated into the classroom in ways that align with current teaching practices. In addition, he shows how educators can adapt these practices to accommodate students’ identities, developmental abilities, and interests. This thought-provoking book supports all educators, especially middle and high school teachers, in teaching for intellectual virtues. _Deep in Thought_ is a philosophical and yet practical guide to one of the most important aims of education: helping students become skilled thinkers and learners.

Caring for Liberalism brings together chapters that explore how liberal political theory, in its many guises, might be modified or transformed to take the fact of dependency on board. In addressing the place of care in liberalism, this collection advances the idea that care ethics can help respond to legitimate criticisms from feminists who argue that liberalism ignores issues of race, class, and ethnicity. The chapters do not simply add care to existing liberal political frameworks; rather, they explore how integrating (...) dependency might leave core components of the traditional liberal philosophical apparatus intact, while transforming other aspects of it. Additionally, the contributors address the design of social and political institutions through which care is given and received, with special attention paid to non-Western care practices. This book will appeal to scholars working on liberalism in philosophy, political science, law, and public policy, and it is a must-read for feminist political philosophers. (shrink)

The concept of wisdom is largely ignored by contemporary philosophers. But given recent movements in the fields of ethics and epistemology, the time is ripe for a return to this concept. This article lays some groundwork for further philosophical work in ethics and epistemology on wisdom. Its focus is the distinction between practical wisdom and theoretical wisdom or between phronesis and sophia . Several accounts of this distinction are considered and rejected. A more plausible, but also considerably more complex, account (...) is offered. The discussion sheds light on the relation between practical wisdom and theoretical wisdom, and on the positive character of each. (shrink)

Virtue Epistemology Virtue epistemology is a collection of recent approaches to epistemology that give epistemic or intellectual virtue concepts an important and fundamental role. Virtue epistemologists can be divided into two groups, each accepting a different conception of what an intellectual virtue is. Virtue reliabilists conceive of intellectual virtues as stable, reliable and truth-conducive cognitive … Continue reading Virtue Epistemology →.

Suppose that you are engaging with someone who is your oppressor, or someone who espouses a heinous view like Nazism or a ridiculous view like flat-earthism. In contexts like these, there is a disparity between you and your interlocutor, a dramatic normative difference across which you are in the right and they are in the wrong. As theorists of humility, we find these contexts puzzling. Humility seems like the *last* thing oppressed people need and the *last* thing we need in (...) dealing with those whose views are heinous or ridiculous. Responding to such people via humility seems uncalled for, even inappropriate. But how could this be, given that humility is a *virtue*? The purpose of the paper is to explore this puzzle. We explain what the puzzle is and then attempt to draw some lessons from it: first, the lesson that the importance of humility is limited in several ways, and second, the lesson that humility nonetheless has several important roles to play, even for people who are in the right in contexts of disparity.

Gottlob Frege has exerted an enormous influence on the evolution of twentieth-century philosophy, yet the real significance of that influence is still very much a matter of debate. This book provides a completely new and systematic account of Frege's philosophy by focusing on its cornerstone: the theory of sense and reference. Two features distinguish this study from other books on Frege. First, sense and reference are placed absolutely at the core of Frege's work; the author shows that no adequate account (...) of the theory can avoid analysing the notion of thought that underpins it, or explaining how it has clarified our concept of judgement. Second, the theory is situated within the development of Frege's thought; the author reveals how the theory caused Frege to alter many of his fundamental views. In doing so the author presents a clearer picture of the problems the theory was intended to solve, and delineates more sharply the characteristic features of Frege's philosophy. (shrink)

According to one prominent account of intellectual humility, it consists primarily of a disposition to “own” one’s intellectual limitations. This account has been criticized for neglecting the _interpersonal _dimensions of intellectual humility. We expect intellectually humble persons to be respectful and generous with their interlocutors and to avoid being haughty or domineering. I defend the limitations-owning account against this objection. I do so in two ways: first, by arguing that some of the interpersonal qualities associated with intellectual humility are qualities (...) expressive of virtues _other_ than intellectual humility; and second, by arguing that, when properly described, the kind of limitations-owning characteristic of intellectual humility in fact is robustly interpersonal. The result is a considerably broader and richer notion of the limitations the owning of which is characteristic of intellectual humility. (shrink)

Traditional logic as a part of philosophy is one of the oldest scientific disciplines. Mathematical logic, however, is a relatively young discipline and arose from the endeavors of Peano, Frege, Russell and others to create a logistic foundation for mathematics. It steadily developed during the 20th century into a broad discipline with several sub-areas and numerous applications in mathematics, informatics, linguistics and philosophy. While there are already several well-known textbooks on mathematical logic, this book is unique in that it is (...) much more concise than most others, and the material is treated in a streamlined fashion which allows the professor to cover many important topics in a one semester course. Although the book is intended for use as a graduate text, the first three chapters could be understood by undergraduates interested in mathematical logic. These initial chapters cover just the material for an introductory course on mathematical logic combined with the necessary material from set theory. This material is of a descriptive nature, providing a view towards decision problems, automated theorem proving, non-standard models and other subjects. The remaining chapters contain material on logic programming for computer scientists, model theory, recursion theory, Godel’s Incompleteness Theorems, and applications of mathematical logic. Philosophical and foundational problems of mathematics are discussed throughout the text. The author has provided exercises for each chapter, as well as hints to selected exercises. About the German edition: …The book can be useful to the student and lecturer who prepares a mathematical logic course at the university. What a pity that the book is not written in a universal scientific language which mankind has not yet created. - A.Nabebin, Zentralblatt. (shrink)

The essays in this volume present versions of feminism that are explicitly liberal, or versions of liberalism that are explicitly feminist.

In the climax to The Protestant Ethic, Max Weber writes of the stahlhartes Gehäuse that modern capitalism has created, a concept that Talcott Parsons famously rendered as the "iron cage." This article examines the status of Parsons's canonical translation; the putative sources of its imagery ; and the more complex idea that Weber himself sought to evoke with the "shell as hard as steel": a reconstitution of the human subject under bureaucratic capitalism in which "steel" becomes emblematic of modernity. Steel, (...) unlike the "element" iron, is a product of human fabrication. It is both hard and potentially flexible. Further, whereas a cage confines human agents, but leaves their powers otherwise intact, a "shell" suggests that modern capitalism has created a new kind of being. After examining objections to this interpretation, I argue that whatever the problems with Parsons's "iron cage" as a rendition of Weber's own metaphor, it has become a "traveling idea," a fertile coinage, in its own right, an intriguing example of how the translator's imagination can impose itself influentially on the text and its readers.

In this chapter, we analyze intellectual patience as a character trait. We look at the contexts that call for patience and at what patience demands in those contexts. Together these constitute our account of patience, though the focus is on patience in the life of the mind. We also consider how patience and perseverance differ, which offers a better understanding of the former and sheds light on how character traits can cooperate. We then consider how to become virtuously patient. We (...) conclude reflecting on some remarks made by the poet Rilke. (shrink)

The terms "a priori" and "a posteriori" refer primarily to how or on what basis a proposition might be known. A proposition is knowable a priori if it is knowable independently of experience. A proposition is knowable a posteriori if it is knowable on the basis of experience. The a priori/a posteriori distinction is epistemological and should not be confused with the metaphysical distinction between the necessary and the contingent or the semantical or logical distinction between the analytic and the (...) synthetic. Two aspects of the a priori/a posteriori distinction require clarification: the conception of experience on which the distinction turns; and the sense in which a priori knowledge is independent of such experience. The latter gives rise to important questions regarding the positive basis of a priori knowledge. (shrink)
