Joseph Hannon has expressed a most surprising objection to Aquinas scholar Prof William E. Carroll in his latest paper “Theological Objections to a Metaphysicalist Interpretation of Creation.” The main claim is that Prof. Carroll misunderstands Aquinas' doctrine of creatio ex nihilo by reducing it to a metaphysical notion, rather than considering it in its full theological sense. In this paper I show Hannon's misinterpretation of Carroll's and Thomas Aquinas' thought, particularly by stressing the dependence that the doctrine (...) of providence through secondary causes has on the doctrine of creatio ex nihilo.

This is a concise book that introduces students to the basics of logical thinking and important mathematical structures that are critical for a solid understanding of logical formalisms themselves as well as for building the necessary background to tackle other fields that are based on these logical principles. Despite its compact and small size, it includes many solved problems and quite a few end-of-section exercises that will help readers consolidate their understanding of the material. This textbook is essential reading for (...) anyone interested in the logical foundations of Informatics, Computer Science, Data Science, Artificial Intelligence, and other related areas. Written with undergraduate students in these disciplines in mind, this book can very well serve the needs of interested and curious readers who wish to get a grasp of the logical principles upon which these fields are built. This book does not require readers to possess math skills beyond those learned in high school. (shrink)

The philosophical interest in the nature, value, and varieties of human understanding has swelled in recent years. This article will provide an overview of new research in the epistemology of understanding, with a particular focus on the following questions: What is understanding and why should we care about it? Is understanding reducible to knowledge? Does it require truth, belief, or justification? Can there be lucky understanding? Does it require ‘grasping’ or some kind of ‘know-how’? This cluster of questions has largely (...) set the research agenda for the study of understanding in epistemology. This article will conclude by discussing some varieties of understanding and highlight directions for future research. (shrink)

This paper aims to solve a puzzle for instrumental conceptions of epistemic normativity. The puzzle is this: if the usefulness of epistemic norms explains their normative grip on us, why does it seem improper to violate these norms even when doing so would benefit us? To solve this puzzle, we argue that epistemic instrumentalists must adopt a more social approach to normativity. In particular, they should not account for the nature of epistemic normativity by appealing to the goals of individual (...) agents. Rather, they should appeal to norms or rules of inquiry that serve our collective goals. We argue that epistemic normativity grows out of our need to promote a deep kind of coordination in our basic epistemic practices. By subscribing to an appropriate system of norms, we can coordinate epistemic rule-following across the community. This makes testimony more trustworthy and reliable. This account not only solves a puzzle about epistemic instrumentalism but also sheds new light on the foundations of normativity and emphasizes the need for a truly social epistemology. (shrink)

It is widely believed that democracies require knowledgeable citizens to function well. But the most politically knowledgeable individuals also tend to be the most partisan, and the strength of partisan identity tends to corrupt political thinking. This creates a conundrum. On the one hand, an informed citizenry is allegedly necessary for a democracy to flourish. On the other hand, the most knowledgeable and passionate voters are also the most likely to think in corrupted, biased ways. What to do? This paper (...) examines this tension and draws out several lessons. First, it is not obvious that more knowledgeable voters will make better political decisions. Second, attempts to remedy voter ignorance are problematic because partisans tend to become more polarized when they acquire more information. Third, solutions to citizen incompetence must focus on the intellectual virtue of objectivity. Fourth, some forms of epistocracy are troubling, in part, because they would increase the political power of the most dogmatic and biased individuals. Fifth, a highly restrictive form of epistocracy may escape the problem of political dogmatism, but epistocrats may face a steeper tradeoff between inclusivity and epistemic virtue than many would like.

What is human understanding and why should we care about it? I propose a method of philosophical investigation called ‘function-first epistemology’ and use this method to investigate the nature and value of understanding-why. I argue that the concept of understanding-why serves the practical function of identifying good explainers, which is an important role in the general economy of our concepts. This hypothesis sheds light on a variety of issues in the epistemology of understanding including the role of explanation, the relationship (...) between understanding-why and knowledge, and the value of understanding-why. I conclude that understanding-why is valuable and yet knowledge plays more important roles in our epistemic life. (shrink)

An intuitive and widely accepted view is that (a) beliefs aim at truth, (b) many citizens have stable and meaningful political beliefs, and (c) citizens choose to support political candidates or parties on the basis of their political beliefs. We argue that all three claims are false. First, we argue that political beliefs often differ from ordinary world-modelling beliefs because they do not aim at truth. Second, we draw on empirical evidence from political science and psychology to argue that most (...) people lack stable and meaningful political beliefs. Third, we claim that the true psychological basis for voting behavior is not an individual’s political beliefs but rather group identity. Along the way, we reflect on what this means for normative democratic theory. (shrink)

What is the primary intellectual aim of philosophy? The standard view is that philosophy aims to provide true answers to philosophical questions. But if our aim is to settle controversy by answering such questions, our discipline is an embarrassing failure. Moreover, taking philosophy to aim at providing true answers to these questions leads to a variety of puzzles: How do we account for philosophical expertise? How is philosophical progress possible? Why do job search committees not care about the truth or (...) falsity of a candidate’s philosophical views? We argue that philosophy does not aim at discovering true answers to philosophical questions. Instead, its primary intellectual aim is understanding. We argue that many familiar aspects of philosophy become intelligible once we accept this hypothesis. (shrink)

This handbook provides an overview of key ideas, questions, and puzzles in political epistemology. It is divided into seven sections: (1) Politics and Truth: Historical and Contemporary Perspectives; (2) Political Disagreement and Polarization; (3) Fake News, Propaganda, Misinformation; (4) Ignorance and Irrationality in Politics; (5) Epistemic Virtues and Vices in Politics; (6) Democracy and Epistemology; (7) Trust, Expertise, and Doubt.

It is widely believed that open and public speech is at the heart of the democratic ideal. Public discourse is instrumentally epistemically valuable for identifying good policies, as well as necessary for resisting domination (e.g., by vocally challenging decision-makers, demanding public justifications, and using democratic speech to hold leaders accountable). But in our highly polarized and socially fragmented political environment, an increasingly pressing question is: do actual democratic societies live up to the ideal of inclusive public speech? In this essay, (...) I explore Maxime Lepoutre's defence of discursive democracy from the challenge of defective public discourse. I argue that political ignorance, dogmatism, and social fragmentation present more formidable challenges to discursive democracy than Lepoutre acknowledges. As a result, his account occasionally veers from warranted optimism to unwarranted idealism. (shrink)

Epistemic democracy is standardly characterized in terms of “aiming at truth”. This presupposes a veritistic conception of epistemic value, according to which truth is the fundamental epistemic goal. I will raise an objection to the standard (veritistic) account of epistemic democracy, focusing specifically on deliberative democracy. I then propose a version of deliberative democracy that is grounded in non-veritistic epistemic goals. In particular, I argue that deliberation is valuable because it facilitates empathetic understanding. I claim that empathetic understanding is an (...) epistemic good that doesn’t have truth as its primary goal. (shrink)

New research suggests that a healthy democracy requires intellectual humility. When citizens are intellectually humble, they are less polarized, more tolerant and respectful of others, and display greater empathy for political opponents. But a flourishing democracy also requires people with political convictions. If the electorate were apathetic, they would not participate in democratic decision-making. Do these two democratic ideals conflict? The standard view in philosophy and psychology is that intellectual humility and political conviction are compatible. In this paper, we challenge (...) the standard view. We appeal to empirical and theoretical work indicating that intellectual humility can result in political apathy or lack of conviction. We conclude by suggesting that there are different varieties of intellectual humility, some aligned with conviction and engagement, and others of a more quietist character. To illustrate this, we sketch a kind of ‘political quietism’ modelled by philosophical thinkers such as Burke and Oakeshott. (shrink)

This book is about the nature and value of knowledge. At its core is a simple idea: we can answer many interesting and difficult philosophical questions by reflecting on the role (purpose, function) of epistemic evaluation in human life. I call this approach ‘function-first epistemology’. I use this method to illuminate the nature and value of knowledge, the foundations of epistemic normativity, the epistemology of testimony, and skepticism.

The truth of skepticism would be depressing and impractical. Our beliefs would be groundless, we would know nothing (or almost nothing) about the world around us, and epistemic success would likely be impossible. But do these negative consequences have any bearing on the truth of skepticism? According to many scholars, they do not. The impractical consequences of skepticism are typically regarded as orthogonal to its truth. For this reason, pragmatic resolutions to skepticism are regularly dismissed. I will argue, however, that (...) skepticism is implausible because it is impractical. In particular, skepticism is implausible because it goes against the point of epistemic evaluation. (shrink)

A striking feature of political discourse is how prone we are to disagree. Political opponents will even give different answers to factual questions, which suggests that opposing parties cannot agree on facts any more than they can on values. This impression is widespread and supported by survey data. I will argue, however, that the extent and depth of political disagreement is largely overstated. Many political disagreements are merely illusory. This claim has several important upshots. I will explore the implications of (...) this idea for theories about voter misinformation, motivated reasoning, public reason liberalism, deliberative democracy, and a number of other issues.

This paper outlines a new type of skepticism that is both compatible with fallibilism and supported by work in psychology. In particular, I will argue that we often cannot properly trust our ability to rationally evaluate reasons, arguments, and evidence (a fundamental knowledge-seeking faculty). We humans are just too cognitively impaired to achieve even fallible knowledge, at least for many beliefs.

Experimental philosophers are often puzzled as to why many armchair philosophers question the philosophical significance of their research. Armchair philosophers, in contrast, are often puzzled as to why experimental philosophers think their work sheds any light on traditional philosophical problems. I argue there is truth on both sides.

This paper is about the ‘threshold problem’ for knowledge, namely, how do we determine what fixes the level of justification required for knowledge in a non-arbitrary way? One popular strategy for solving this problem is impurism, which is the view that the required level of justification is partly fixed by one’s practical reasoning situation. However, this strategy has been the target of several recent objections. My goal is to propose a new version of impurism that solves the threshold problem without (...) succumbing to these criticisms. (shrink)

Many epistemologists think we can derive important theoretical insights by investigating the English word ‘know’ or the concept it expresses. However, fewer than six percent of the world’s population are native English speakers, and some empirical evidence suggests that the concept of knowledge is culturally relative. So why should we think that facts about the word ‘know’ or the concept it expresses have important ramifications for epistemology? This paper argues that the concept of knowledge is universal: it is expressed by (...) some word in every natural language. I also explore the implications of this thesis for philosophical methodology. (shrink)

Two of the most orthodox ideas in epistemology are fallibilism and purism. According to the fallibilist, one can know that a particular claim is true even though one’s justification for that claim is less than fully conclusive. According to the purist, knowledge does not depend on practical factors. Fallibilism and purism are widely assumed to be compatible; in fact, the combination of these views has been called the ‘ho-hum,’ obvious, traditional view of knowledge. But I will argue that fallibilism and (...) purism are incompatible. The best explanation for fallibilism requires one to reject purism, while maintaining purism should lead one to reject fallibilism. It follows that the orthodox view of knowledge is deeply mistaken.

This paper examines two major challenges to epistemic theories of democracy: the “authority dilemma” and the “epistemic gamble.” The first is a conceptual challenge, suggesting that epistemic democracy is inherently self-undermining. The second is a normative challenge, asserting that the case for democracy should not rely on precarious epistemic grounds. I argue that both challenges fail, demonstrating that epistemic theories of democracy withstand these two prominent objections.

A prevalent political narrative is that we are facing an epistemological crisis, where many citizens no longer care about truth and facts. Yet the view that we are living in a post-truth era relies on some implicit questionable empirical and normative assumptions. The post-truth rhetoric converts epistemic issues into motivational issues, treating people with whom we disagree as if they no longer believe in or care about truth. This narrative is also dubious on epistemic, moral, and political grounds. It is (...) epistemically dubious in being largely insensitive to the problem of complexity in politics; it is morally dubious because “post-truth” is often a derogatory label for individuals or groups that are deemed stupid, irrational, or morally compromised; and it is a politically toxic neologism because it purports to use the language of ‘truth’ as a weapon against power, yet these truth-claims are often themselves attempts to exert power over others by delegitimizing their perspectives. While it may seem as if truth and democracy are on especially bad terms lately, politics and truth have long had a vexed relationship, and moral panics about the value of truthfulness in politics are as old as politics itself.

This paper explores how the purpose of the concept of knowledge affects knowledge ascriptions in natural language. I appeal to the idea that the role of the concept of knowledge is to flag reliable informants, and I use this idea to illuminate and support contextualism about ‘knows’. I argue that practical pressures that arise in an epistemic state of nature provide an explanatory basis for a brand of contextualism that I call ‘practical interests contextualism’. I also answer some questions that (...) contextualism leaves open, particularly why the concept of knowledge is valuable, why the word ‘knows’ exhibits context-variability, and why this term enjoys such widespread use. Finally, I show how my contextualist framework accommodates plausible ideas from two rival views: subject-sensitive invariantism and insensitive invariantism. This provides new support for contextualism and develops this view in a way that improves our understanding of the concept of knowledge. (shrink)

Knowledge ascriptions of the form ‘S knows that p’ are a central area of research in philosophy. But why do humans think and talk about knowledge? What are knowledge ascriptions for? This article surveys a variety of proposals about the role of knowledge ascriptions and attempts to provide a unified account of these seemingly distinct views.

I acquired many intellectual debts while writing What’s the Point of Knowledge?, but I am especially indebted to my three symposiasts. David Henderson’s work helped me to appreciate the value of thinking about the point of epistemic evaluation; Catherine Elgin’s writings prompted me to investigate the purpose of the concept of understanding; and Krista Lawlor’s 2013 book revealed important connections between three of my primary epistemological interests: the role of epistemic evaluation, the semantics of knowledge claims and the work of (...) J.L. Austin. It is therefore an honour to have such personally influential scholars engage with my work. Their thoughtful, generous and philosophically rich comments have provided yet another opportunity to clarify my thinking and develop some ideas further. (shrink)

This paper defends the epistemological doctrine of fallibilism from recent objections. In “The Myth of Knowledge” Laurence BonJour argues that we should reject fallibilism for two main reasons: first, there is no adequate way to specify what level of justification is required for fallible knowledge; second, we cannot explain why any level of justification that is less than fully conclusive should have the significance that makes knowledge valuable. I will reply to these challenges in a way that allows me to (...) make progress on a number of important issues in contemporary epistemology: epistemic value, the functional roles of knowledge attributions, experimental epistemology, skepticism, the Gettier problem, and the lottery paradox. My argument is motivated by appealing to various insights derived from the method of ‘practical explication’, particularly the idea that a central purpose of the concept of knowledge is to flag reliable informants. My conclusion is that various practical and theoretical considerations derived from the method of practical explication support the fallibilist conception of knowledge. (shrink)

Is human nature something that the natural and social sciences aim to describe, or is it a pernicious fiction? What role, if any, does ”human nature’ play in directing and informing scientific work? Can we talk about human nature without invoking---either implicitly or explicitly---a contrast with human culture? It might be tempting to think that the respectability of ”human nature’ is an issue that divides natural and social scientists along disciplinary boundaries, but the truth is more complex. The contributors to (...) this collection take very different stances with regard to the idea of human nature. They come from the fields of psychology, the philosophy of science, social and biological anthropology, evolutionary theory, and the study of animal cognition. Some of them are ”human nature’ enthusiasts, some are sceptics, and some say that human nature is a concept with many faces, each of which plays a role in its own investigative niche. Some want to eliminate the notion altogether, some think it unproblematic, others want to retain it with reforming modifications. Some say that human nature is a target for investigation that the human sciences cannot do without, others argue that the term does far more harm than good. The diverse perspectives articulated in this book help to explain why we disagree about human nature, and what, if anything, might resolve that disagreement.

In this paper we study the category of hyper MV-algebras and we prove that it has a terminal object and a coequalizer. We show that Jia's construction can be modified to provide a free hyper MV-algebra by a set. We use this to show that in the category of hyper MV-algebras the monomorphisms are exactly the one-to-one homomorphisms.

In this paper, we consider a collection of filters of a BL-algebra A. We use the concept of congruence relation with respect to filters to construct a uniformity which induces a topology on A. We study the properties of this topology regarding different filters.

In this paper we introduce n -fold implicative basis logic and the related algebras called n -fold implicative BL-algebras. Also we define n -fold implicative filters and we prove some relations between these filters and construct quotient algebras via these filters.

It is almost universally presumed that knowledge is factive: in order to know that p it must be the case that p is true. This idea is often justified by appealing to knowledge ascriptions and related linguistic phenomena; i.e., an utterance of the form ‘S knows that p, but not-p’ sounds contradictory. In a recent article, Allan Hazlett argues that our ordinary concept of knowledge is not factive. From this it seems to follow that epistemologists cannot appeal to ordinary language (...) to justify the truth condition of knowledge. More significantly, Hazlett claims that epistemologists theorizing about knowledge should not concern themselves with the ordinary concept of knowledge as revealed by knowledge ascriptions and related linguistic phenomena. My paper has two goals: first, to defend the orthodox view that the ordinary concept of knowledge is factive; second, to undermine Hazlett’s claim that epistemologists should not theorize about knowledge on the basis of how ‘knows’ is used in everyday speech.

If epistemic contextualism is correct, then knowledge attributions do not have stable truth-conditions across different contexts. John Hawthorne, Timothy Williamson, and Patrick Rysiew argue that this unstable picture of knowledge attributions undermines the role that knowledge reports play in storing, retrieving, and transmitting useful information. Contrary to this view, I argue that the truth-conditions of knowledge attributions are more stable than critics have claimed, and that contextualism is compatible with the role knowledge attributions play in storing, retrieving, and transmitting information (...) across contexts. In particular, I discuss a social dimension of ‘knowledge’ that limits contextual variability. This indicates a new way of characterizing contextualism. (shrink)

This chapter discusses the nature and value of political disagreement, with reference to contemporary work in political philosophy. I will attempt to answer the following questions: Why do we disagree? Is political disagreement a good thing? Do we have a duty to disagree? Should we expect consensus or mere compromise in politics? When is civil disobedience a justified way to express disagreement with the law? Is consensus a threat to democracy?

This chapter explores an unappreciated psychological dimension of intellectual humility. In particular, I argue there is a plausible connection between intellectual humility and epistemic egocentrism. Epistemic egocentrism is a well-known cognitive bias – often called ‘the curse of knowledge’ – whereby an agent attributes his or her own mental states to other people. I hypothesize that an individual who exhibits this bias is more likely to possess a variety of traits that are characteristic of intellectual humility. This is surprising because (...) intellectual humility is often regarded as an antidote to cognitive biases, whereas I claim that a particular cognitive bias (namely, the curse of knowledge) may help foster an intellectual virtue.

In Why It's OK to Speak Your Mind, Hrishikesh Joshi argues that the open exchange of ideas is essential for the flourishing of individuals and society. He provides two arguments for this claim. First, speaking your mind is essential for the common good: we enhance our collective ability to reach the truth if we share evidence and offer different perspectives. Second, speaking your mind is good for your own sake: it is necessary to develop your rational faculties and exercise intellectual (...) independence, both of which are essential for living a good life. In this paper, I consider the implications of Joshi’s argument and raise several objections to his view. (shrink)

Drawing on new empirical data, a group of experimental philosophers have argued that one of the most popular and influential forms of skepticism is much less interesting and much less worrisome than philosophers have thought. Contrary to this claim, I argue that this brand of skepticism remains as threatening as ever. My argument also reveals an important limitation of experimental philosophy and sheds light on the way professional philosophers should go about the business of doing philosophy.

Knowledge is central to epistemology. Indeed, the word ‘epistemology’ comes from the Greek word epistêmê, which is often translated as ‘knowledge.’ But what is knowledge? Why do we value it? How is it acquired? And how much of it do we have? This article explores the nature, significance, sources, and extent of human knowledge.

According to some powerful skeptical arguments, we know almost nothing. Contextualist theories of knowledge ascriptions have been developed with an eye toward resisting skepticism. Have the contextualists succeeded? After briefly outlining their view, I will consider whether contextualism about knowledge ascriptions provides a satisfactory response to one of the most popular and influential forms of skepticism. I conclude with some questions for the contextualist. As we’ll see, the effectiveness of the contextualist solution to skepticism is far from settled.

Political epistemology is a newly flourishing area of philosophy, but there is no comprehensive overview to this burgeoning field. This chapter maps out the terrain of political epistemology, highlights some of the key questions and topics of this field, draws connections across seemingly disparate areas of work, and briefly situates this field within its historical and contemporary contexts.

This article summarizes the key ideas in my book, ‘What's the Point of Knowledge?’. First, I articulate the method of function first epistemology, which looks at our epistemology from a practical point of view. Second, I outline my core hypothesis about the purpose of the concept of knowledge, namely, we have this concept to identify reliable informants. Third, I explain how this account is used to resolve a number of epistemological issues. I also draw connections between pragmatism and my own (...) theory of knowledge. (shrink)

In his overview of recent work on intellectual humility, Nathan Ballantyne (2021) highlights some of the potential ‘dark sides’ of intellectual humility (IH) and calls for a critical study of the ‘value-theory’ of IH. In this article, we sketch out three ways that IH may threaten political conviction. We end our response by arguing that some forms of IH include different kinds of quietism about political convictions, which do not necessarily equate with a lack of conviction.

In this article, I reply to comments on my book by Georgi Gardiner and Joshua DiPaolo. I will first reply to Gardiner's comments, focusing primarily on her doubts about the adjudicative power of function-first epistemology. I will then reply to DiPaolo, who argues that I have misidentified that primary function of the concept of knowledge.

In When is True Belief Knowledge? (2012) Richard Foley proposes an original and strikingly simple theory of knowledge: a subject S knows some proposition p if and only if S truly believes that p and does not lack any important information. If this view is correct, Foley allegedly solves a wide variety of epistemological problems, such as the Gettier problem, the lottery paradox, the so-called ‘value problem’, and the problem of skepticism. However, a central component of his view is that (...) whether a true belief counts as knowledge depends on the importance of the information that one has or lacks. My paper raises doubts about whether there is a non-circular way to distinguish important information from unimportant information. I argue that there is no way to distinguish important information from unimportant information without ultimately making reference to knowledge; thus, Foley’s new theory of knowledge does not achieve its goals.
