Knowledge and Intellectual Skill KNOWLEDGE AND INTELLECTUAL SKILL by JOSHUE OROZCO A Dissertation submitted to the Graduate School-New Brunswick Rutgers, The State University of New Jersey in partial fulfillment of the requirements for the degree of Doctor of Philosophy Graduate Program in Philosophy written under the direction of Ernest Sosa and approved by ________________________ ________________________ ________________________ ________________________ New Brunswick, New Jersey October, 2009 ABSTRACT OF THE DISSERTATION Knowledge and Intellectual Skill By JOSHUE OROZCO Dissertation Director: Ernest Sosa This dissertation defends the position that knowledge is best understood as a true belief acquired through the manifestation of intellectually virtuous performance. I argue that intellectually virtuous performance requires intellectual responsibility but not a characteristic motivation. I distinguish my view from other conceptions of intellectual virtues; particularly the virtue reliabilism of Ernest Sosa and John Greco and the virtue responsibilism of Linda Zagzebski. I argue that intellectual virtues are best understood along the lines of Aristotelian skills by looking at various puzzles in epistemology and showing how this view can make more progress in solving these puzzles than its competitors. ii Acknowledgements and Dedication There are many people to whom I owe many thanks for their continued support and mentorship. I am particularly grateful for the philosophical guidance and instruction that I received over the last five years from the philosophy faculty at Rutgers University; particularly from Ruth Chang, Alvin Goldman, Jeff McMahan, and Dean Zimmerman. I am especially indebted to Ernest Sosa—my supervisor—for his invaluable training and encouragement, and for his remarkable ability to help develop projects and arguments aimed against his own views. My fellow graduate students, both inside and outside of Rutgers, have had just as big an impact in my growth as a philosopher, providing rich discussion both inside and outside of the seminar room. Geoff Anders, Luvell Anderson, Josh Armstrong, Matthew Benton, Pavel Davydov, Jonathan Ichikawa, Alex Jackson, David Manley, Gary Osmundson, Blake Roeber, Andrew Sepielli, Ryan Wasserman and Stephanie Wykstra have been especially helpful. Finally, I have received special support from friends and family members who without them this would not have been possible. To my parents who have given me tremendous love and resources. And most importantly to my wonderful wife, Mandy, who has been nothing but supportive and has stood behind me even in the dead of New Jersey winters. I dedicate this to her. iii Table of Contents Abstract ii Acknowledgements and Dedication iii Introduction: Knowledge and Intellectual Skill 1 Chapter 1: Epistemic Rationality and Practical/Moral Considerations: The Need for Intellectual Skill 7 Chapter 2: Luck, Lotteries, and Epistemic Responsibility 40 Chapter 3: The Value of Virtuous Behavior: An Answer the Value Problem of Knowledge 72 Chapter 4: Epistemic Responsibility and Doxastic Control 100 Chapter 5: Testimonial Knowledge in Children: I Can Trust You Now … But Not Later 125 Curriculum Vita 156 iv 1 Introduction: Knowledge and Intellectual Skill Gettier’s 1963 paper brought the traditional analysis of knowledge—as justified true belief—into question. In response much ink was spilled trying to amend the traditional account of justification. And as the 20th century came to a close, some felt an impasse had been reached between competing accounts of justification: in particular between internalist and externalist conceptions of justification. One characteristic feature of the various modified accounts of justification was their focus on the properties of beliefs. Justified beliefs need to be undefeated, safe, sensitive, rationally entailed by one’s evidence, reliably produced, sufficiently coherent, foundationally based, etc. However, in 1980 Ernest Sosa—in “The Raft and the Pyramid”—suggested that focusing on the properties of beliefs was excessive and misplaced, and that we should instead look to the properties of individuals to make epistemic evaluations, in a way suggested by virtue ethics. Sosa proposed that whether a belief qualifies as knowledge depends primarily on the intellectual virtues of the agent. If an agent’s intellectual virtues are sufficiently responsible for a belief’s truth, then the agent has knowledge. The set of theories that fall under the sub-discipline “virtue epistemology” center around the thesis that intellectual agents and their “intellectual virtues” are the primary points of epistemic evaluation, with beliefs receiving a derivative evaluation. However, there is serious dispute within virtue epistemology regarding the nature of one’s intellectual virtues. If one has knowledge only when the truth of one’s belief is credited to one’s intellectually virtuous traits, or virtuous performance, then it is important to understand what it is for a trait, or performance, to be intellectually virtuous. For Sosa an 2 intellectual virtue is a belief forming faculty or process that is reliable at getting at the truth. Things like our perceptual faculties, memory, introspection, and perhaps intuition are considered intellectual virtues. Accordingly, Sosa’s virtue-reliabilism is an externalist theory of knowledge—it is not necessary that the conditions for knowledge be accessible to the believer. In contrast to Sosa, Linda Zagzebski takes intellectual virtues to be perfectly analogous to moral virtues. She argues that one deficiency in the virtue-reliabilist accounts is their inability to accommodate the similarities that epistemology has with ethics. She goes on to defend the view that intellectual virtues are a subspecies of moral virtues. “An intellectual virtue, like a moral virtue,” says Zagzebski “has a motivational component as well as a component of reliable success in reaching the end (if any) of the motivational component. What makes intellectual virtues intellectual is that they (or most of them) include motive dispositions connected with the motive to get truth…”1 Intellectual virtues are character traits like courage, thoroughness, carefulness, humility, etc., and therefore epistemic evaluations should mirror moral evaluations in virtue ethics ultimately being based on what the intellectually virtuous person would do in a given situation. The virtue-reliabilism of Sosa and the moral-analogue version of Zagzebski characterize the two main strands of virtue theories in epistemology, and both versions have many attractive features. The reliabilst framework provides many resources for dealing with skepticism and accommodating Gettier-style worries. The moral-analogue framework can easily accommodate parallels between epistemic and ethical evaluations. Our evaluations of beliefs closely resembles our evaluations of actions, and 1 See Zagzebski’s introduction in her (2001): 5. 3 epistemlogists ongoing concern over epistemic justification is an example of this resemblance. My dissertation is work in virtue epistemology. As such, it follows Sosa’s suggestion that some epistemic evaluations are best analyzed in terms of properties of individuals—namely her intellectual virtues and/or virtuous activity—rather than properties of beliefs. I focus primarily on evaluations of knowledge and epistemic rationality/justification. Chapter Summaries In Chapters 1-4 I argue that the two main conceptions of intellectual virtues have serious drawbacks, and defend an intermediate understanding of intellectual virtues that retains the attractions of both theories but avoids their shortcomings. I follow Zagzebski in taking intellectual virtues to be more analogous to moral virtues than Sosa’s conception. Intellectual virtues are character traits like courage, humility, and open-mindedness that require repeated intentional and virtuous behavior for their development. However, I think Zagzebski pushes the analogy too far. Intellectual virtues are not perfectly analogous to moral virtues. First, intellectual virtues are not structurally motivational; unlike moral virtues they do not require a characteristic motivation. Second, moral virtues are not necessarily reliable at achieving their aim. One can be benevolent, kind, or generous despite continuously failing to bring about one’s intended aim. In contrast, in order for open-mindedness or intellectual courage to be considered intellectual virtues they have to be reliable ways of getting at the truth. Intellectual virtues, on my account, are more akin to Aristotelian skills than to moral virtues. I argue for this intermediate position by looking at some contemporary problems in epistemology. 4 Chapter 1 examines the nature of epistemic rationality/justification and its relation to other domains of normativity; particularly, moral/practical norms and evaluations. I argue that although evaluations of epistemic rationality/justification should be distinguished from moral evaluations, it is plausible that moral and practical considerations are relevant to evaluations of epistemic rationality/justification. I argue that an adequate account of epistemic rationality should make use of the notion of intellectually responsible behavior, and that moral and practical considerations are relevant to whether intellectual behavior is responsible. I then amend this account by arguing that epistemic rationality/justification also requires reliability. I propose that epistemic rationality is best conceived as intellectually skillful behavior.

  • Critical Inquiry As Virtuous Truth-Telling: Implications of Phronesis and Parrhesia ______
    ______________________________________________________________________________ Critical Inquiry as Virtuous Truth-Telling: Implications of Phronesis and Parrhesia ______________________________________________________________________________ Austin Pickup, Aurora University Abstract This article examines critical inquiry and truth-telling from the perspective of two comple- mentary theoretical frameworks. First, Aristotelian phronesis, or practical wisdom, offers a framework for truth that is oriented toward ethical deliberation while recognizing the contingency of practical application. Second, Foucauldian parrhesia calls for an engaged sense of truth-telling that requires risk from the inquirer while grounding truth in the com- plexity of human discourse. Taken together, phronesis and parrhesia orient inquirers to- ward intentional truth-telling practices that resist simplistic renderings of criticality and overly technical understandings of research. This article argues that truly critical inquiry must spring from the perspectives of phronesis and parrhesia, providing research projects that aim at virtuous truth-telling over technical veracity with the hope of contributing to ethical discourse and social praxis. Keywords: phronesis, praxis, parrhesia, critical inquiry, truth-telling Introduction The theme of this special issue considers the nature of critical inquiry, specifically methodological work that remains committed to explicit goals of social justice and the good. One of the central concerns of this issue is that critical studies have lost much of their meaning due to a proliferation of the term critical in educational scholarship. As noted in the introduction to this issue, much contemporary work in education research that claims to be critical may be so in name only, offering but methodological techniques to engage in critical work; techniques that are incapable of inter- vening in both the epistemological and ontological formations of normative practices in education.

Budziszewski Frontmatter More Information Commentary on Thomas Aquinas’s Virtue Ethics Although St. Thomas Aquinas famously claimed that his Summa Theologiae was written for “beginners,” contemporary readers i nd it unusually difi cult. Now, amid a surge of interest in virtue ethics, J. Budziszewski clarii es and analyzes the text’s challenging arguments about the moral, intellectual, and spiritual virtues, with a spotlight on the virtue of justice. In what might be the i rst contemporary commentary on Aquinas’s virtue ethics, he juxtaposes the original text with paraphrase and detailed discussion, guiding us through its complex arguments and classical rhetorical i gures. Keeping an eye on con- temporary philosophical issues, he contextualizes one of the greatest virtue theorists in history and brings Aquinas into the interdisciplinary debates of today. His brisk and clear style illuminates the most crucial of Aquinas’s writ- ings on moral character and guides us through the labyrinth of this difi cult but pivotal work. J. Budziszewski is Professor of Government and Philosophy at the University of Texas at Austin, where he also teaches courses in religious studies and in the law school. His work includes numerous books as well as a blog, The Underground Thomist .

  • Forthcoming in Episteme Educating for Intellectual Virtue
    CORE Metadata, citation and similar papers at core.ac.uk Provided by PhilPapers Forthcoming in Episteme Educating for Intellectual Virtue: a critique from action guidance Ben Kotzee (Birmingham), J. Adam Carter (Glasgow) & Harvey Siegel (Miami) Abstract: Virtue epistemology is among the dominant influences in mainstream epistemology today. An important commitment of one strand of virtue epistemology – responsibilist virtue epistemology (e.g., Montmarquet 1993; Zagzebski 1996; Battaly 2006; Baehr 2011) – is that it must provide regulative normative guidance for good thinking. Recently, a number of virtue epistemologists (most notably Baehr, 2013) have held that virtue epistemology not only can provide regulative normative guidance, but moreover that we should reconceive the primary epistemic aim of all education as the inculcation of the intellectual virtues. Baehr’s picture contrasts with another well-known position – that the primary aim of education is the promotion of critical thinking (Scheffler 1989; Siegel 1988; 1997; 2017). In this paper – that we hold makes a contribution to both philosophy of education and epistemology and, a fortiori, epistemology of education – we challenge this picture. We outline three criteria that any putative aim of education must meet and hold that it is the aim of critical thinking, rather than the aim of instilling intellectual virtue, that best meets these criteria. On this basis, we propose a new challenge for intellectual virtue epistemology, next to the well-known empirically- driven ‘situationist challenge’. What we call the ‘pedagogical challenge’ maintains that the intellectual virtues approach does not have available a suitably effective pedagogy to qualify the acquisition of intellectual virtue as the primary aim of education.

The examination will be conducted in English. Faculty examiner: Professor Bonnie Kent (The Department of Philosophy, UC Irvine). Abstract Stöpfgeshoff, A. 2018. The Structure of the Virtues. A Study of Thomas Aquinas’s and Godfrey of Fontaines's Accounts of Moral Goodness. 173 pp. Uppsala: Department of Philosophy, Uppsala University. ISBN 978-91-506-2713-8. This dissertation is a study of Thomas Aquinas’s (1225–1274) and Godfrey of Fontaines’s (d. 1306) moral philosophies. In this study, I conduct a detailed analysis of two Aristotelian commitments concerning the character virtues, namely, The Plurality of the Character Virtues and The Connection of the Character Virtues. Both Aquinas and Godfrey think that there are many distinct character virtues (such as moderation and justice), however, one cannot (perfectly) possess these character virtues in separation from each other. In Chapter I, it is established that Aquinas believes in the plurality of the character virtues not because of a specific account of the human soul, but because he is committed to a plurality in what he calls “the notion of goodness.” In Chapter II, it is argued that Aquinas’s account of virtuous action requires that there be a likeness between a person and their actions in terms of the notion of goodness explored in Chapter I.

Rosanas 2 1 Faculty of Economics and Business Studies, Universitat Oberta de Catalunya, Rambla del Poblenou, 156, 08018 Barcelona, Spain 2 IESE Business School, Universidad de Navarra, Avinguda Pearson, 21 08034 Barcelona, Spain; [email protected] * Correspondence: [email protected]; Tel.: +34-932-535-791 Received: 21 December 2019; Accepted: 27 January 2020; Published: 6 February 2020 Abstract: We analyze the status of virtues in management by going in some depth into the two main virtues, justice and practical wisdom. We next study how ethics requires that all virtues should be present under the ideal concept of a ‘unity of virtues’ for a completely wise person and discuss the practical limitations of this concept. Then, we draw a framework for decision making depending on whether the decision maker possesses justice and practical wisdom or lacks one of them and then discuss which one is better to have. We conclude that justice is more important, as it is about setting objectives and prioritizing, whereas practical wisdom is about attaining these objectives, once listed, in a rationally wise and contextual way. Hence, we conclude that objectives (justice) must come first, because this makes it more likely that, in the end, practical wisdom is developed, and thus we end up having the two virtues. Keywords: Justice; Fairness; Virtue ethics; Practical wisdom 1. Introduction Business ethics has become one of the important fields in management in the last few decades.

  • Contemplating Friendship in Aristotle's Ethics
    Chapter One Contemplating Friendship in Aristotle’s Ethics Aristotle begins the Nicomachean Ethics by embracing the claim that all human activity aims at the good. Living from 384–322 BC, and having been a student in Plato’s Academy for nearly twenty years before founding his own philosophical school in Athens, the Lyceum, in 335 BC, Aristotle identifies the highest human good as happiness eudaimonia( ). Aristotle defines happiness as an activity of soul in accord with the reason of a serious person, and thus as an activity of soul in accord with virtue. Such a definition is problematic, however, because virtue is divided by Aristotle into two different types: moral virtue and intellectual virtue. Which of these virtues for Aristotle constitutes happiness is one of the most contested debates in the contemporary literature on the Nicomachean Ethics. On one side of this debate are ranged scholars such as J. L. Ackrill and David Bostock who hold that Aristotle has an “inclusive” view of happiness.1 This means that the happy life requires the practice, in some form, of both the moral and the intellectual virtues. Scholars on the other side of the debate, such as C. D. C. Reeve and Thomas Nagel, believe that Aristotle has an “exclusive” or “dominant” view of happiness.2 This view holds that happiness is grounded in the intellectual virtue of contemplation, which is separable from and superior to moral virtue. I argue that Aristotle’s text comprehends both the “inclusive” and “exclusive” views of happiness attributed to it. In acts of moral virtue, Aristotle argues, reason determines the mean and guides the passions to it, which is then usually followed by an external action of the body.

Intellectual virtues are different from and shouldn’t be confused with other kinds of cognitive strengths, including raw intelligence or intellectual skills (Baehr 2011: Ch. 2). More precisely, this guide is for college and university instructors interested in teaching their respective subject matters—whatever these might be—in ways that will help their students better appreciate, practice, and cultivate virtues like curiosity, open- mindedness, intellectual humility, and intellectual courage.

  • Why Intellectual Virtues Matter
    KRITIKE VOLUME ELEVEN NUMBER TWO (DECEMEBER 2017) 93-103 Article Why Intellectual Virtues Matter Bernardo N. Caslib, Jr. Abstract: Following Linda Zagzebski’s pioneering work in virtue epistemology, intellectual virtues have been at the receiving end of great interest in several sectors of the philosophical world. Zagzebski largely thinks that the importation of the concept of virtue, primarily an ethical concept, into epistemology holds the key to problems in epistemology. A challenge to Zagzebski, however, is the question of the innate compatibility of the anatomies of the two realms, ethics and epistemology. Can the concept of virtue be applied to epistemology, too? Is there a real connection between moral and intellectual virtues? This paper attempts at providing a way by which this challenge can be dealt with. By examining Julia Annas’ arguments, and the concept of phronesis as a key Aristotelian virtue, this paper forwards the position that there is a huge overlap between intellectual and moral virtues, that contrary to claims of incompatibility, one can even facilitate the attainment of the other, and that the life of truth may after all be the life well lived. Keywords: Aristotle, virtue, intellectual virtues, ethics I. Introduction hat is wisdom, as a virtue? In the Filipino context, wisdom is roughly translated as karunungan. A person who is marunong (or W alternatively, madunong) is virtuous because he has a particular insight into the nature of truth and reality. Oftentimes, karunungan is ascribed to the elders who are assumed to be experienced in life (and sometimes, learned too). Karunungan is not something that one can attain through mere schooling, however.

  • 1 Francisco De Vitoria on Prudence and the Nature of Practical Reasoning the History of the Concept of Prudence in Moral Philoso
    Francisco de Vitoria on Prudence and the Nature of Practical Reasoning The history of the concept of prudence in moral philosophy is often portrayed as a history of loss. According to the classical version of this view, it is, more specifically, a loss in moral significance: On Aristotle's account, there is a constitutive link between prudence and morality. Prudence provides morality with a sense for the particularities and the contingency of the situations in which agent has to act. And morality, by way of a substantial conception of the good life for human beings, provides prudence with an ethical impregnation that sets it apart from mere cleverness or cunning.1 Aquinas and other medieval authors largely adopt this Aristotelian doctrine, though they relocate it in the wider framework of Christian moral theology.2 In the philosophy of modernity, however, the constitutive link between morality and prudence is cut off by authors like Machiavelli, Hobbes, and Kant. They take prudence to be the ability to identify the most effective means to goals set no longer by morality but by the agent's contingent desires. So for them, prudence is mere cleverness or cunning after all.3 There is, however, an alternative to this classical version of the history of the concept of prudence. It is also essentially a history of loss, but it suggests that the history of the concept of prudence must be divided in a rather different manner: not between antiquity and the Middle Ages on the one hand and modernity on the other, but rather between antiquity on the one hand and the Middle Ages and modernity on the other; and not for moral, but for epistemological reasons.4 According to this view, the overly Aristotelian interpretation of Aquinas's moral philosophy implied in the classical version of the history of prudence has been justly criticized for overlooking an important difference between the moral theories of Aristotle and Aquinas: For Aristotle, there can be no such thing as a moral or practical science.

  • Ethical and Epistemic Belief Justification
    Ethical and Epistemic Belief Justification By Erik Halterman Submitted in partial fulfillment of the requirements for the Degree of Bachelor of Arts in Philosophy at Haverford College First reader: Kathleen Wright Second Reader: Danielle Macbeth 4/24/2015 Abstract: This essay seeks to develop a new theory of intellectual virtue. It rejects the popular reliabilist account as a fundamental misunderstanding of the metaphysical nature of virtue. Namely, reliabilism reduces virtues to something akin to mere habits or tendencies when they are in fact normative, fallible capacities. Further work is needed to explain this, however, as the disjunctivist account of capacities suggests that capacities are only relevant when successfully exercised. This leads to the key insight of this new theory of intellectual virtue: the notion of ethical justification for belief as separate from epistemic justification. This notion is essential for explaining why we sometimes praise knowers for their false beliefs and why we can rightfully call these people intellectually virtuous. These knowers are achieving success of a sort which cannot be captured by reliabilist virtue epistemological theories. Armed with this new theory of intellectual virtue as directed at ethically justified beliefs, we are able to answer several problems which have vexed virtue epistemologists, and to which reliabilists have given particularly unsatisfying answers. We are able to explain how historical scientists such as Aristotle who were unreliable in their scientific theories can rightly be called intellectually virtuous, as they certainly seem to be. We are also able to answer Gettier and Gettier-type problems by clarifying that knowledge must be epistemically justified true belief and demonstrating that these cases always involve ethically justified true belief.
