In this paper, I develop a serious new dilemma involving necessary truths for safety-based theories of knowledge, a dilemma that I argue safety theorists cannot resolve or avoid by relativizing safety to either the subject’s basis or method of belief formation in close worlds or to a set of related or sufficiently similar propositions. I develop this dilemma primarily in conversation with Duncan Pritchard’s well-known, oft-modeled safety-based theories of knowledge. I show that Pritchard’s well-regarded anti-luck virtue (...) theory of knowledge and his recently proposed (allegedly superior) anti-risk virtue theory of knowledge clearly succumb to the dilemma, and so they are inadequate as they stand. If Pritchard’s safety-based theories of knowledge are shown to be inadequate by the dilemma that is developed in this paper, then a number of other safety-based theories of knowledge (e.g., Beddor and Pavese’s, Luper’s, Dutant’s, early Pritchard’s, and others) look to be in jeopardy in this connection as well.

In this important new text, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the accepted definition of knowledge as justified true belief, Lehrer explores the truth, belief and justification conditions on the way to a thorough examination of foundation theories of knowledge, externalism and naturalized epistemologies, internalism and modern coherence theories as well as recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes that external (...) factors must be matched by appropriate internal ones to yield knowledge. Readers of Professor Lehrer's earlier book _Knowledge_ will want to know that this text adopts the framework of that classic text. But _Theory of Knowledge_ is a completely rewritten and updated version of that book that has been simplified throughout for student use. (shrink)

This new edition of the classic Contemporary Theories of Knowledge has been significantly updated to include analyses of the recent literature in epistemology.

Knowledge-first theories of justification are theories of justification that give knowledge priority when it comes to explaining when and why someone has justification for an attitude or an action. The emphasis of this article is on knowledge-first theories of justification for belief. As it turns out, there are a number of ways of giving knowledge priority when theorizing about justification, and what follows is a survey of more than a dozen existing options that (...) have emerged in the early 21st century since the publication of Timothy Williamson’s *Knowledge and Its Limits*. This article traces several of the general theoretical motivations that have been offered for putting knowledge first in the theory of justification. This is followed by an examination of existing knowledge-first theories of justification and their standing objections. These objections are largely, but not exclusively, concerned with the extensional adequacy of knowledge-first theories of justification. There are doubtless more ways to give knowledge priority in the theory of justified belief than are covered here, but the survey is instructive because it highlights potential shortcomings that would-be knowledge-first theorists of justification may wish either to avoid or else to be prepared with a suitable error theory. This entry concludes with a reflection about the extent to which the short history of, arguably, failed attempts to secure an unproblematic knowledge-first account of justified belief has begun to resemble the older Gettier dialectic.

In this impressive second edition of Theory of Knowledge, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the traditional definition of knowledge as justified true belief, Lehrer explores the truth, belief, and justification conditions on the way to a thorough examination of foundation theories of knowledge,the work of Platinga, externalism and naturalized epistemologies, internalism and modern coherence theories, contextualism, and recent reliabilist and causal theories. Lehrer gives all (...) views careful examination and concludes that external factors must be matched by appropriate internal factors to yield knowledge. This match of internal and external factors follows from Lehrer’s new coherence theory of undefeated justification. In addition to doing justice to the living epistemological traditions, the text smoothly integrates several new lines that will interest scholars. Also, a feature of special interest is Lehrer’s concept of a justification game.This second edition of Theory of Knowledge is a thoroughly revised and updated version that contains several completely new chapters. Written by a well-known scholar and contributor to modern epistemology, this text is distinguished by clarity of structure, accessible writing, and an elegant mix of traditional material, contemporary ideas, and well-motivated innovation.

First published in 1984 as part of The Collected Papers of Bertrand Russell, Theory of Knowledge represents an important addition to our knowledge of Russell's thought. In this work Russell attempts to flesh out the sketch implicit in The Problems of Philosophy. It was conceived by Russell as his next major project after Principia Mathematica and was intended to provide the epistemological foundations for his work. Russell's subsequent difficulties in presenting his theory of knowledge, brought on by (...) what he considered to be devastating criticisms of Wittgenstein, led to both his abandonment of this work and to a major transformation in his thought. Theory of Knowledge, now available for the first time in paperback, gives us a picture of one of the great minds of the twentieth century at work. It is possible to see the unsolved problems left without disguise or evasion. This second edition has retained the full scholarly introduction. The photographs of the manuscript, appendices, and notes on textual matters have been eliminated to provide a concise and accessible guide to understanding both Russell's own thought and his relationship with Wittgenstein.

Intentional action is, in some sense, non-accidental, and one common way action theorists have attempted to explain this is with reference to control. The idea, in short, is that intentional action implicates control, and control precludes accidentality. But in virtue of what, exactly, would exercising control over an action suffice to make it non-accidental in whatever sense is required for the action to be intentional? One interesting and prima facie plausible idea that we wish to explore in this paper is (...) that control is non-accidental in virtue of requiring knowledge – either knowledge-that or knowledge-how (e.g., Beddor and Pavese 2021; cf., Setiya 2008; 2012 and Habgood-Coote 2018). We review in detail some key recent work defending such knowledge-centric theories of control, and we show that none of these accounts holds water. We conclude with some discussion about how control opposes the sort of luck intentional action excludes without doing so by requiring knowledge (that- or how). (shrink)

The book attempts, in as comprehensive a way as possible, to make clear the central issues for the theory of knowledge, so as to provide a framework for that subject and also to indicate something of the way in which, as the author believes, the issues should be faced.

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. (shrink)

Originally published in 1949. Understanding the questions is the major problem when beginning philosophy. This book does not attempt to provide the answers, but defines the questions and shows by example how they should be tackled. Subjects treated include the nature of the objects of thought and judgment; truth and error in belief; perception and knowledge of the material world; the status and function of memory.

This paper discusses the theory of knowledge based on the idea of dynamical space. The goal of this effort is to comprehend the knowledge that remains beyond the human domain, e.g., of the artificial cognitive systems. This theory occurs in two versions, weak and strong. The weak version is limited to knowledge in which retention and articulation are performed through the discourse. The strong version is general and is not limited in any way. In the weak version, (...) knowledge is represented by the trajectories of discourses in time, in a dynamical space called the discursive space, which has an arbitrary number of dimensions. Given space is used to represent a given part of knowledge. A manifold is introduced to represent knowledge with a wider scope. The strong version is an extrapolation of the weak version to cover all forms of knowledge, not necessarily human or manifesting in language. The use of dynamical space construction allows one to formalize knowledge as such. Such an effort requires us to initially consider knowledge as mainly a social and linguistic phenomenon, which also could be presented as a result of the evolution of the understanding of knowledge that took place in the 20th century.

For millennia, knowledge has eluded a precise definition. The industrialization of knowledge (IoK) and the associated proliferation of the so-called knowledge communities in the last few decades caused this state of affairs to deteriorate, namely by creating a trio composed of data, knowledge, and information (DIK) that is not unlike the aporia of the trinity in philosophy. This calls for a general theory of knowledge (ToK) that can work as a foundation for a science of (...) knowledge (SoK) and additionally distinguishes knowledge from both data and information. In this paper, I attempt to sketch this generality via the establishing of both knowledge structures and knowledge systems that can then be adopted/adapted by the diverse communities for the respective knowledge technologies and practices. This is achieved by means of a formal–indeed, mathematical–approach to epistemological matters a.k.a. formal epistemology. The corresponding application focus is on knowledge systems implementable as computer programs. (shrink)

This comprehensive and accessible book is designed for use by students following the Theory of Knowledge course in the International Baccalaureate (IB) Diploma Programme.

The Theory of Knowledge: A Thematic Introduction explains the main ideas and problems of contemporary epistemology while avoiding technical detail. Comprehensive and rich in illustrations and examples, it highlights contemporary debates over the definition, sources, and limits of human knowledge, and covers major topics including the nature of belief, theories of truth, epistemic justification, the Gettier problem, skepticism, and epistemic rationality. Its discussions identify important connections between traditional epistemological questions and cognitive science, the history of science, the (...) sociology of knowledge, and cross-cultural studies. The book culminates with a focus on questions regarding epistemological method and an examination of the roots of contemporary analytic approaches to epistemology. The authors defend a distinctive position regarding epistemological method, called broad explanationism, that incorporates some insights from naturalism in epistemology. The volume is enhanced by a glossary of important epistemological terms and suggestions for further reading. Easily accessible to beginning students in philosophy, The Theory of Knowledge serves as an ideal text for courses in the theory of knowledge and will also appeal to general readers interested in philosophy.

Having entered into the problem structuring methods, system dynamics (SD) is an approach, among systems’ methodologies, which claims to recognize the main structures of socio-economic behaviors. However, the concern for building or discovering strong philosophical underpinnings of SD, undoubtedly playing an important role in the modeling process, is a long-standing issue, in a way that there is a considerable debate about the assumptions or the philosophical foundations of it. In this paper, with a new perspective, we have explored theory of (...) knowledge in SD models and found strange similarities between classic epistemological concepts such as justification and truth, and the mechanism of obtaining knowledge in SD models. In this regard, we have discussed related theories of epistemology and based on this analysis, have suggested some implications for moderating common problems in the modeling process of SD. Furthermore, this research could be considered a reword of system dynamics modeling principles in terms of theory of knowledge. (shrink)

This book is an accessible introduction to contemporary epistemology, the theory of knowledge. It introduces traditional topics in epistemology within the context of contemporary debates about the definition, sources, and limits of human knowledge. Rich in examples and written in an engaging style, it explains the field while avoiding technical detail. It relates epistemology to work in cognitive science and defends a plausible version of explanationism regarding epistemological method.

In books such as The World Within the World and The Anthropic Cosmological Principle, astronomer John Barrow has emerged as a leading writer on our efforts to understand the universe. Timothy Ferris, writing in The Times Literary Supplement of London, described him as "a temperate and accomplished humanist, scientist, and philosopher of science--a man out to make a contribution, not a show." Now Barrow offers the general reader another fascinating look at modern physics, as he explores the quest for a (...) single, unifying theory that will unlock nature's secrets. Theories of Everything is more than a history of science, more than a popular report on recent research and discoveries. Barrow provides a reflective, intelligent commentary on what a true Theory of Everything would be--its ingredients, its limitations, and what it could tell us about the universe. Never before, he writes, have physicists been so confident and so eager in the hunt for this "cosmic Rosetta Stone," as he calls it: "a single all-embracing picture of all the laws of nature from which the inevitability of all things seen must follow with unimpeachable logic." He lays out eight essential ingredients for a Theory of Everything and then explores each in turn, tracing how our knowledge has developed and how scientific discovery relates to our changing philosophy and religious thought in each area. Some of these ingredients are obvious--the laws of nature must be explained, for example, as well as its organizing principles--but others may be surprising, such as broken symmetries and selection biases. A Theory of Everything must account for the fact that the universe is "messy and complicated," he tells us, and for the limitations imposed by the questions we ask and the information we can obtain. The key lies in the remarkable capacity of mathematics to express the fundamental workings of the physical world--a language that the human mind is uniquely equipped to understand and manipulate. Barrow examines what mathematics actually is and describes how it makes the universe intelligible and provides a path to the underlying coherence in nature--which has led, in fact, to arguments that the universe itself is a vast computer. Yet even the most complete theory, even the most comprehensive mathematical explanation, cannot account for the uncomputable varieties of human experience and thought. "No non-poetic account of reality," he writes, "can be complete." In a field where the authorities converse in equations and mathematical notations, John Barrow speaks with the voice of thoughtful and knowledgeable humanist. Written with eloquence and expertise, Theories of Everything establishes a new perspective on humanity's efforts to explain the universe. (shrink)

Contextualist theories of knowledge offer a semantic hypothesis to explain the observed contextual variation in what people say they know, and the difficulty people have resolving skeptical paradoxes. Subject or speaker relative versions make the truth conditions of “S knows that p” depend on the standards of either the knower’s context (Hawthorne and Stanley) or those of the speaker’s context (Cohen and DeRose). Speaker contextualism avoids objections to subject contextualism, but is implausible in light of evidence that “know” (...) does not behave like an indexical. I deepen and extend these criticisms in light of recent defenses by contextualists (including Ludlow). Another difficulty is that whether certain standards are salient or intended does not entail that they are the proper standards. A normative form of contextualism on which the truth of a knowledge claim depends on the proper standards for the context is more promising, but still unsatisfactory whether the view is speaker or subject relative. I defend alternative explanations for the observed linguistic and psychological data: a pragmatic account for some cases and a cognitive account for others. 1. (shrink)

As teorias epistemológicas do rastreamento sustentam que o conhecimento é uma relação real entre o agente cognitivo e seu ambiente. Os estados cognitivos de um agente epistêmico fazem o rastreamento da verdade das proposições que são objeto de conhecimento ao embasarem a crença em indicadores confiáveis da verdade (evidência, razões, ou métodos de formação de crença). A novidade nessa abordagem é que se dá pouca ênfase no tipo de justificação epistêmica voltada ao fornecimento de procedimentos de decisão doxástica ou regras (...) de responsabilidade epistêmica. Este artigo oferece um pouco da história das teorias de rastreamento e, então, defende-as contra muitas objeções que se pretendem (equivocadamente) refutadoras dessas teorias. PALAVRAS – CHAVE – Teorias de rastreamento. Nozick. Dretske. Conhecimento. ABSTRACT Tracking theories of knowledge maintain that knowledge is a real relation between cognitive agent and environment. Cognitive states of a knower track the truth of known propositions by basing belief on reliable indicators of truth (evidence, reasons, or belief forming methods). The novelty of this approach is that it places little emphasis on epistemic justification of a kind that aims at guiding epistemic agents by giving doxastic decision procedures or rules of epistemic responsibility. This paper gives some of the history of tracking theories, and then defends them against many of the objections most often judged (mistakenly) to refute tracking theories.
