In “The Sources of Knowledge,” Robert Audi distinguishes what he calls the “four standard basic sources” by which we acquire knowledge or justified belief: perception, memory, consciousness, and reason. With the exception of memory, he distinguishes each of the above as a basic source of knowledge. Audi contrasts basic sources with nonbasic sources, concentrating on testimony. After clarifying the relationship between a source and a ground, or “what it is in virtue of which (...) one knows or justifiedly believes,” Audi evaluates the basic sources’ individual and collective autonomy as well as their vulnerability to defeasibility. He also examines the relationship of coherence to knowledge and justification, noting the distinction between a negative dependence on incoherence and a positive dependence on coherence. (shrink)

Testimony is a special challenge in epistemology. Human life as we know it would be impossible without it; we commonly accept it without question; and only the highly skeptical doubt that from it we gain much knowledge about matters on which we lack independent evidence. In my theory of testimony, it figures as an essential source of knowledge in our lives, but not as a basic source of it; and the way in which testimony yields justification for (...) believing its content is very different from the way in which it yields knowledge. Isabelle Keßels, David Lambert, and Christian Quast have produced a long and detailed study of my treatment of the topic, and here I can note only some important aspects of it and seek to discuss them in ways that may advance understanding of some major aspects of the topic.

A theory of information is developed in which the informational content of a signal (structure, event) can be specified. This content is expressed by a sentence describing the condition at a source on which the properties of a signal depend in some lawful way. Information, as so defined, though perfectly objective, has the kind of semantic property (intentionality) that seems to be needed for an analysis of cognition. Perceptual knowledge is an information-dependent internal state with a content corresponding to (...) the information producing it. This picture of knowledge captures most of what makes knowledge an important cpistcmological notion. It also avoids many of the problems infecting traditional justificational accounts of knowledge (knowledge as [justified, true belief those (unlike knowledge) having a content that can be either true or false (e.g., belief) – are described in terms of the way internal (presumably neural) structures acquire during learning a certain information-carrying role. The content of these structures (whether true or false) is identified with the kind of information they were developed to carry. (shrink)

In this work Pollock attempts to recast the epistemological enterprise. Traditional epistemology has been centered on the search for truth conditions. It has been assumed that unless these are found the sceptic’s attack on knowledge claims cannot be conclusively answered. Pollock contends that traditional epistemologists have been barking up the wrong tree. The problem of epistemology is not to prove the trustworthiness of the justification condition. The proper task of epistemologists is to reveal the logical connection between the (...) source of our knowledge and the knowledge the source provides. This is to be done through an analysis of the meaning of statements, and the meaning of a statement is determined by the "justification conditions of it and its denial." Epistemological issues, such as perception, other minds, historical knowledge, a priori knowledge, amount to "nothing more than describing the justification conditions for statements in the different areas of knowledge." But, then what is meant by "justification conditions"? (shrink)

One of the most exciting debates in philosophy of imagination in recent years has been over the epistemic use of imagination where imagination epistemically contributes to justifying beliefs and acquiring knowledge. This paper defends “generationism about imagination” according to which imagination is a generative source, rather than a preservative source, of justification. In other words, imagination generates new justification above and beyond prior justification provided by other sources. After clarifying the generation/preservation distinction (Section 2), we (...) present an argument for generationism about imagination, which can be divided into two parts; the philosophical part and the empirical part. In the philosophical part of our argument (Section 3), we claim that generationism about imagination follows from what we call “INACCESSIBILITY”. According to INACCESSIBILITY, imagination is properly constrained by the imaginative constrainers (i.e., the prior representations that constrain the development of a scenario in imagination) to which non-imaginative belief-forming processes do not have access. In the empirical part of our argument (Section 4), we claim that INACCESSIBILITY is plausible in light of relevant studies and theories in the empirical literature, especially the literature on mental simulation (Section 4.1), core cognition (Section 4.2), and intuitive physics (Section 4.3).

The paper aims to show how in practice the requirement to maintain the coherence of the system of beliefs and the corresponding behavior of «spontaneous beliefs» within the concept of empirical knowledge by L. Bonjour can be correlated. The main example considered is P. Kosso’s arguments about the reliability of Thucydides’ «History» connected with the idea of possibility of justification restricted to a single source of evidence. As a heuristics we deal with the problem of how to establish (...) the contextual dependence of inference and, in general, of the structure of the justification of knowledge within the given situation. First, it is possible to extend L. Bonjour’s concept with the idea of the nonmonotonic nature of justification and coherence of the original system of beliefs. Such a step, in particular, will make it possible to abandon the need for the argument «from meta-justification». Second, the interpretation of «spontaneous beliefs», their justification and facts fixing whether these beliefs violate the coherence of the original system or not, as patterns (in the sense of the fundamental concept of existence by D. Ross) makes it possible (for example, due to the exact understanding of «interpretative perspective» and «functional role» of the projection) to meaningfully interpret the «context dependence» in each particular case.

This book provides an accessible and up-to-date discussion of contemporary theories of perceptual justification that each highlight different factors related to perception, i.e., conscious experience, higher-order beliefs, and reliable processes. The book’s discussion starts from the viewpoint that perception is not only one of our fundamental sources of knowledge and justification, but also plays this role for many less sophisticated animals. It proposes a scientifically informed reliabilist theory which can accommodate this fact without denying that some (...) of our epistemic abilities as human perceivers are special. This allows it to combine many of our intuitions about the importance of conscious experience and higher-order belief with the controversial thesis that perceptual justification is fundamentally non-evidential in character.

Throughout her work, Audre Lorde maintains that her self-preservation in the face of oppression depends on acting from the recognition and valorization of her feelings as a deep source of knowledge. This claim, taken as a portrayal of agency, poses challenges to standard positions in ethics, epistemology, and moral psychology. This article examines the oppositional agency articulated by Lorde’s thought, locating feeling, poetry, and the power she calls “the erotic” within her avowed project of self-preservation. It then explores the (...) implications of taking seriously Lorde’s account, particularly for theorists examining ethics and epistemology under nonideal social conditions. For situations of sexual intimacy, for example, Lorde’s account unsettles prevailing assumptions about the role of consent in responsibility between sexual partners. I argue that obligations to solicit consent and respect refusal are not sufficient to acknowledge the value of agency in intimate encounters when agency is oppositional in the way Lorde describes.

The claim that we want to put forward is that Thomas Kuhn ’s growth of knowledge concept is drawn upon Heidegger’s epistemology. To bolster the tenet the corresponding works of both thinkers are considered. As a result, the one-to-one correspondence between the key propositions of Heideggerian epistemology and the basic tenets of Kuhn ’s growth of knowledge model is dawned. The tenets under consideration include the holistic nature of a paradigm, the incommensurability thesis, conventional status of a paradigm (...) caused by pragmatist way of its vocabulary justification and even the basic instance – connection between Aristotelean and Newtonian mechanics. It is conjectured that an indirect influence of Heidegger upon Kuhn should be taken into account to explain the isomorphism. For instance, through the works of Alexandre Koyré admired by Kuhn. As is well-known, Koyré had close professional links with another Russian émigré – Alexandre Kojev – who presented in his 1933-1939 Paris lectures Hegel’s “Phenomenology of Spirit” seen through the cognitive lens of Heideggerian phenomenology. Key words: Martin Heidegger, Thomas Kuhn, growth of knowledge, paradigm, incommensurability thesis, holism, pragmatism. (shrink)

In this book, Phillips gives an overview of the contribution of Nyaya--the classical Indian school that defends an externalist position about knowledge as well as an internalist position about justification. Nyaya literature extends almost two thousand years and comprises hundreds of texts, and in this book, Phillips presents a useful overview of the under-studied system of thought. For the philosopher rather than the scholar of Sanskrit, the book makes a whole range of Nyaya positions and arguments accessible to (...) students of epistemology who are unfamiliar with classical Indian systems.

This article starts from the assumption that there are various innate contributions to our view of the world and explores the epistemological implications that follow from this. Specifically, it explores the idea that if certain components of our worldview have an evolutionary origin, this implies that these aspects accurately depict the world. The simple version of the argument for this conclusion is that if an aspect of mind is innate, it must be useful, and the most parsimonious explanation for its (...) usefulness is that it accurately depicts the world. There are a number of important criticisms of this argument. These include the idea that evolutionary justifications are circular, that evolved mental content and principles are not necessarily accurate, and that, if the argument is taken seriously, it has some highly dubious consequences. These criticisms necessitate various qualifications to the initial argument. Nonetheless, it is argued that, in some cases, important conclusions can be drawn about the world from an analysis of evolved contributions to our view of the world. An evolutionary approach cannot provide an ultimate justification for any belief; however, in certain circumstances, it supports the conclusion that a given belief is a reasonable first approximation. To the extent that innate content and principles pertain to topics in metaphysics, they can be viewed as a naturalistic source of metaphysical knowledge. (shrink)

Social knowledge, for the most part, is knowledge through testimony. This essay is an overview of the epistemology of testimony. The essay separates knowledge from justification, characterizes testimony as a source of belief, explains why testimony is a source of knowledge, canvasses arguments for anti-reductionism and for reductionism in the reductionism vs. anti-reductionism debate, addresses counterexamples to knowledge transmission, defends a safe basis account of testimonial knowledge, and turns to social norms as a (...) partial explanation for the reliability of testimony.

Within the evidence-based medicine construct, clinical expertise is acknowledged to be both derived from primary experience and necessary for optimal medical practice. Primary experience in medical practice, however, remains undervalued. Clinicians’ primary experience tends to be dismissed by EBM as unsystematic or anecdotal, a source of bias rather than knowledge, never serving as the “best” evidence to support a clinical decision. The position that clinical expertise is necessary but that primary experience is untrustworthy in clinical decision-making is epistemically incoherent. (...) Here we argue for the value and utility of knowledge gained from primary experience for the practice of medicine. Primary experience provides knowledge necessary to diagnose, treat, and assess response in individual patients. Hierarchies of evidence, when advanced as guides for clinical decisions, mistake the relationship between propositional and experiential knowledge. We argue that primary experience represents a kind of medical knowledge distinct from the propositional knowledge produced by clinical research, both of which are crucial to determining the best diagnosis and course of action for particular patients.

This paper explains how the notion of justification transmission can be used to ground a notion of knowledge transmission. It then explains how transmission theories can characterise schoolteacher cases, which have prominently been presented as counterexamples to transmission theories.

Epistemology has historically focused on individual inquirers conducting their intellectual affairs in total isolation from one another. Methodological solipsism aside, however, it is incontestable that people’s opinions are massively influenced by their community and culture, by the written and spoken words of others, both past and present. This has led recent epistemologists to pay greater attention to the social dimensions of knowledge, especially to the role of testimony as a source of justification. The aim of Knowledge in (...) a Social World is to articulate a more systematic and wide-ranging conception of social epistemology, a conception that forges links with both empirical and policy-oriented disciplines that study the place of knowledge in society. On the one hand, it steers social epistemology along paths continuous with mainstream epistemology and philosophy of science; on the other, it carries epistemology into greater contact than is customary with political philosophy, legal philosophy, and such new or peripheral fields as Internet epistemology and philosophy of education. Although it never abandons the theoretical mission of epistemology, it also makes concerted forays into what may be called “applied epistemology”. (shrink)

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.

The paper is concerned with the epistemological status of testimony and the question of what may confer justification on true testimonial beliefs and enable us to call such beliefs knowledge. In particular, it addresses certain anti-reductionist arguments in the epistemology of testimony and their incompatibility with the grammatical categories of egophoricity (conjunct/disjunct marking) and evidentiality (information source marking) present in the architecture of natural languages. First, the tradition of epistemological individualism and its rationale are discussed, as well as (...) certain attempts within this tradition to include testimony-based beliefs in the body of legitimate and rational beliefs. The next section is concerned with the anti-reductionist approach to testimonial beliefs and some arguments supporting ‘the credulity principle’ grounded in Thomas Reid's philosophy of common sense. The last two sections show how the anti-reductionist argumentation is threatened with an insoluble dilemma when considered in the context of languages with the grammatical categories of egophoricity (conjunct/disjunct marking) and evidentiality (information source marking). Special attention is paid to the justificatory role of egophoric and evidential marking; how these grammatical categories may influence the process of belief formation, and consequently, how this bears upon the nature of justification for testimonial beliefs. The final conclusion of the paper is that the anti-reductionist claim concerning the directness and non-inferential nature of testimonial knowledge is bound to meet objections grounded in the structure of many natural languages. This leads to a paradox: in discussion with reductionism, anti-reductionists do seek support for their arguments in common sense beliefs reflected in everyday language, and, on the other hand, their claims are incompatible with the linguistic data found in a number of natural languages.

This book offers a unified collection of published and unpublished papers by Robert Audi, a renowned defender of the rationalist position in ethics. Taken together, the essays present a vigorous, broadly-based argument in moral epistemology and a related account of reasons for action and their bearing on moral justification and moral character. Part I details Audi's compelling moral epistemology while Part II offers a unique vision of ethical concepts and an account of moral explanation, as well as a powerful (...) model of moral realism. Part III extends this account of moral explanation to moral responsibility for both actions and character and to the relation between virtue and the actions that express it. Part IV elaborates a theory of reasons for action that locates them in relation to three of their traditionally major sources: desire, moral judgment, and value. Clear and illuminating, Audi's introduction outlines and interconnects the self-contained but cumulatively arranged essays. It also places them in relation to classical and contemporary literature, and directs readers to large segments of thematically connected material spread throughout the book. Audi ends with a powerfully synthetic final essay. (shrink)

In this British Academy lecture, Popper argues for a reformulation of epistemological questions. In the past we have asked for the ultimate sources of knowledge and thus begged for authoritarian answers. He charges that this question of origins is relevant to the determination of meaning but not to the determination of truth. The historical sections are often interesting in their own right, especially those on the conspiracy theory of ignorance.--R. H. K.

_An Introduction to the Theory of Knowledge_ guides the reader through the key issues and debates in contemporary epistemology. Lucid, comprehensive and accessible, it is an ideal textbook for students who are new to the subject and for university undergraduates. The book is divided into five parts. Part I discusses the concept of knowledge and distinguishes between different types of knowledge. Part II surveys the sources of knowledge, considering both _a priori_ and _a posteriori_ knowledge. (...) Parts III and IV provide an in-depth discussion of justification and scepticism. The final part of the book examines our alleged knowledge of the past, other minds, morality and God. O'Brien uses engaging examples throughout the book, taking many from literature and the cinema. He explains complex issues, such as those concerning the private language argument, non-conceptual content, and the new riddle of induction, in a clear and accessible way. This textbook is an invaluable guide to contemporary epistemology. (shrink)

A prominent trend in recent work on Hume’s epistemology has it that the concerns of Part Three of Book One of the Treatise, ‘Of knowledge and probability’, are purely descriptive and explanatory. Don Garrett and David Owen have argued that Hume’s primary interest lies in showing that it is not reason but rather the imagination that enables us to use experience to form beliefs about the future. Reason cannot be responsible for such beliefs; for if it were, it would (...) have to proceed by means of the principle ‘that those instances of which we have had no experience, resemble those, of which we have had experience’; and there is no source for that principle in either experience or reason itself. Of course, no belief is shown to be unjustified simply by the fact that it is produced by the imagination and not by reasoning. For Hume’s reasons for scepticism about the trustworthiness of the imagination, the reader has to wait until Part Four, and its claim that ‘there is a direct and total opposition…betwixt those conclusions we form from cause and effect, and those that persuade us of the continu’d and independent existence of body’. Louis Loeb agrees that Book One of the Treatise demands to be read as having two stages, the first constructive, the second destructive. But he has an intriguing and unusual take on the first stage. He believes that there is more to Part Three than mere description and explanation. There is in addition a theory of justification. In this part of the Treatise Hume shows himself to have a ‘pre-theoretical’ commitment to the view that, all things being equal, beliefs produced by certain belief-forming mechanisms within the faculty of imagination count as knowledge; and also seeks to give this commitment a theoretical rationale. If Loeb is right, the old view of Hume as a sceptic about induction needs to be revised even more radically than Garrett and Owen would have us believe. (shrink)

This study seeks to understand knowledge transfer practices within the Muslim business community in Edinburgh. It investigates how knowledge transfer practices are managed on a day to day basis, examines the route of development and justification for these practices into meaningful knowledge transfer processes, and explores the underlying perspective of knowledge from the knowledge transfer practitioners view of knowledge transfer practices in a business context. In particular, the study seeks explanations for such practices (...) with reference to both a knowledge-based and a resource-based view of the firm. Due to the multifarious phenomena of knowledge transfer, and to allow a scope necessary to establish epistemological and empirical evidence from literature, a two stage literature review process was adopted. The majority of literature expounds an argument in which knowledge and knowledge transfer processes in a business context are embedded within a set of real world dimensions, based on causal relationships. Literature determines that it is overcoming difficulties with this framework which is critical for a businesses ability to manage, utilise and extract value from multiple internal and external sources of knowledge. Four broad themes were identified, from which most literature supported this argument: Psychological, Organisational, Philosophical and Cultural. Data collection and analysis were carried out in two phases. Phase one was based on ethnographic participant observation which proved unsuccessful due to an underestimation of the complexity of the participants personal perspective and researcher bias. Phase two was informed by the difficulties encountered in phase one and proved successful in capturing meaningful data. (shrink)

Open peer commentary on the article “Going Beyond Theory: Constructivism and Empirical Phenomenology” by Urban Kordeš. Upshot: Consistent with constructivism, phenomenology attempts to ground knowledge in an understanding of subjectivity. Although the phenomenological method can serve as a source of new insights and important critique of the conventional modes of understanding, the method’s effectiveness in the context of justification remains problematic.

This paper critically examines currently influential transparency accounts of our knowledge of our own beliefs that say that self-ascriptions of belief typically are arrived at by “looking outward” onto the world. For example, one version of the transparency account says that one self-ascribes beliefs via an inference from a premise to the conclusion that one believes that premise. This rule of inference reliably yields accurate self-ascriptions because you cannot infer a conclusion from a premise without believing the premise, and (...) so you cannot infer from a premise that you believe the premise unless you do believe it. I argue that this procedure cannot be a source of justification, however, because one can be justified in inferring from p that q only if p amounts to strong evidence that q is true. This is incompatible with the transparency account because p often is not very strong evidence that you believe that p. For example, unless you are a weather expert, the fact that it will rain is not very strong evidence that you believe it will rain. After showing how this intuitive problem can be made precise, I conclude with a broader lesson about the nature of inferential justification: that beliefs, when justified, must be underwritten by beliefs, when justified, must be underwritten by evidential relationships between the facts or propositions which those beliefs represent.

The aim of this article is to map the intellectual structure of scholarship on economic and social value in the sport industry. Given that bibliometric techniques are specially appropriate for identifying the intellectual structures of a field of knowledge and complement traditional literature reviews, a co-citation bibliometric analysis has been applied. This kind of analysis identifies networks of interconnections. Therefore, we aim to detect both the most and the least active research areas in this field, as well as their (...) sub-disciplinary composition. There is an abundance of literature on sport efficiency and economic efficiency in the sport industry, our main conclusion is the identification of a literature gap in regard to social value in sport organisations, which is expected to be a research opportunity for scholars. This is in line with the lack of standardisation in the measurement for social value in sport organisations. In fact, similar to analysis undertaken in the past few decades of other industries with contributions to stakeholders and the multi-fiduciary theory of stakeholders, both the creation of social value indicators for sport entities and the empirical analysis of social efficiency in sport institutions, are identified and outlined as future areas of research. Therefore, this bibliometric analysis will contribute to determine the future challenges that this area of research will face in the following years so as to fill the literature gap identified.

In this paper I make some critical comments on John McDowell’s Mind and World and offer suggestions as to how it might be possible to solve John McDowell’s problem of finding a safe passage between the Scylla of the “Myth of the Given” (Sellars) and the Charybdis of a Davidsonian linguistic coherentism. McDowell’s defense of a minimal empiricism depends on the largely unargued and ultimately untenable assumption that epistemic justification can only operate at the level of conceptual or propositional (...) entities. Drawing on contemporary analytic philosophy of mind and continental philosophy of subjectivity, I try to show that epistemic normativity already comes into play at two levels of experience—sensory observation and self-knowledge—that are more basic than the conceptual. What McDowell needs is a philosophy of subjectivity that would allow him to identify primary sources of epistemic normativity that are both subjectcentered and pre-conceptual. (shrink)

Epistemology is a branch of philosophy that studies the origin, nature and limits of human knowledge. Contemporary epistemology is a theory of knowledge in terms of reasons, evidence, justification and explanation. This book shows how Anglo-American philosophers captivated by the power of modern science and concomitant advances in logic and mathematics mistook knowledge itself to be reducible to the propositions of science and logic. Ethics, along with metaphysics and religion, were cast off as mere expressions of (...) sentiment at best, or as utter nonsense at worst. Is science the only source of knowledge? Can ethics count as knowledge? Are there kinds of knowledge beyond epistemology? This book develops innovative answers to these and other related questions. (shrink)

In artificial intelligence (AI), responses generated by machine-learning models (most often large language models) may be unfactual information presented as a fact. For example, a chatbot might state that the Mona Lisa was painted in 1815. Such phenomenon is called AI hallucinations, seeking inspiration from human psychology, with a great difference of AI ones being connected to unjustified beliefs (that is, AI “beliefs”) rather than perceptual failures). -/- AI hallucinations may have their source in the data itself, that is, the (...) source content, or in the training procedure, i.e. the way the knowledge was encoded in the model’s parameters, so that errors in encoding and decoding textual and non-textual representations can cause hallucinations. In this paper, we will observe how such errors come to life and how they might be mitigated. For this purpose, we will analyze the usability of justification logics, to behave as a proof checker for validating the correctness of large language models’ (LLM) responses. Justification logic was developed by S. Artemov, and later on mostly by Artemov and M. Fitting, deriving its main idea from the logic of proofs (LP): knowledge and belief modalities are seen as justification terms, i.e. t:X stands for t is a (proper) justification for X. Justification logic originated from attempts to create semantics for intuitionistic logic where proofs were the most proper justifications, but in further development, justification logic could be applied to different kinds of justifications). With the recent attempts to mitigate incorrect LLM responses, we will analyze various guardrails that are currently used for LLM responses, and see how the logic of justification may provide its benefits as an AI safety layer against false data.

In this paper I deal with epistemological issues that stem from the hypothesis that reasoning is not only a means of transmitting knowledge from premise-beliefs to conclusion-beliefs, but also a primary source of knowledge in its own right. The idea is that one can gain new knowledge on the basis of suppositional reasoning. After making some preliminary distinctions, I argue that there are no good reasons to think that purported examples of knowledge grounded on pure reasoning (...) are just examples of premise-based inferences in disguise. Next, I establish what kinds of true propositions can to a first approximation be known on the basis of pure reasoning. Finally, I argue that beliefs that are competently formed on the basis of suppositional reasoning satisfy both externalist and internalist criteria of justification. (shrink)

Recent work on the imagination has stressed the epistemic significance of imaginative experiences, notably in justifying modal beliefs. An immediate problem with this is that modal beliefs appear to admit of justification through the mere exercise of rational capacities. For instance, mastery of the concepts of square, circle, and possibility should suffice to form the justified belief that a square circle is not possible, and mastery of the concepts of pig, flying, and possibility should suffice to form a justified (...) belief that a flying pig is possible. It is thus unnecessary to try to imagine a square circle or a flying pig to justify these beliefs. In this paper, I consider three ways to defend the epistemic role of imagination in modal epistemology against this challenge. One claims that modal beliefs simply admit of justification by two separate sources: rational capacities and imaginative experience. Another holds that while beliefs about logical or conceptual modality can be justified entirely by rational capacities, beliefs about metaphysical modality require imaginative experiences. The third, which I defend, is the idea that imagination is relevant in the first instance not to modal knowledge but to modal understanding: even where imaginative experience is unnecessary for the justification of modal beliefs, it is indispensable for directly grasping certain modal propositions.

This work, written from a neo-Pyrrhonian perspective, is an examination of contemporary theories of knowledge and justification. It takes ideas primarily found in Sextus Empiricus's Outlines of Pyrrhonism, restates them in a modern idiom, and then asks whether any contemporary theory of knowledge meets the challenges they raise. The first part, entitled "Gettier and the Problem of Knowledge," attempts to rescue our ordinary concept of knowledge from those philosophers who have assigned burdens to it that (...) it cannot bear. Properly understood, Fogelin shows that the concept of knowledge is unproblematic. The second part of this study, called "Agrippa and the Problem of Justification," examines Agrippa's contribution to Pyrrhonism, a systematic reduction of its procedures which came to be known as the "Five Modes Leading to the Suspension of Belief." These modes present a completely general procedure for refuting any claim a dogmatist might make. Though largely unnoticed, there is, according to Fogelin, an uncanny resemblance between problems posed by Agrippa's "Five Modes" and those that contemporary epistemologists address under the heading of a theory of justification. Fogelin examines the strongest contemporary theories of justification--in both foundationalist and anti-foundationalist forms. The conclusion is that recent philosophical writings on justification have made no significant progress in responding to the Pyrrhonian problems these writings have addressed. (shrink)

The claim that knowledge is grounded on a basic, non-inferentially grasped set of principles, which seems to be Aristotle’s view, in contemporary epistemology can be seen as part of a wider foundationalist account. Foundationalists assume that there must be some premise-beliefs at the basis of every felicitous reasoning which cannot be themselves in need of justification and may not be challenged. They provide justification for truths based on these premises, which Aristotle unusually call principles (archái). Can Aristotle (...) be considered a foundationalist? Are his first principles necessary premises to right inferences? We will look at the issue here. (shrink)

There are two ways to think about knowledge: From the bottom-up point of view, knowledge is an early arrival on the evolutionary scene; it is what animals need in order to coordinate their behavior with the environmental conditions.

The perception of intellectual life in Greek antiquity by the representatives of the European Enlightenment of the 18th century favoured the establishment of the cult of reason. Myth as a potential source of knowledge was disregarded: instead, the monopoly of truth-finding through pure rationalisation was asserted. This tendency, positing, as it did, reason in opposition to myth, did a signal disservice to the realities of intellectual life among the ancient Greeks. Nevertheless, these distortions of the Enlightenment have conditioned our (...) approach to education and have led to our privileging of reason as a mode of enquiry right up to the present day. The ancient Greek intellectuals (i.e. the pre-Socratic philosophers, the early historiographers, philosophers of the classical age) did not set myth (mythos) and reason (logos) in opposition to each other. In fact, they benefited from both as differing modes of enquiry, each in its own right and possessing its own value. Plato, in his reasoning, was much concerned with the proper use of mythical narrative. In one of his dialogues, he even coined a new term for explaining how mythical topics and motifs should be exploited as a source of knowledge. This term is mythologia, and it first occurs in Plato's Republic (394b). The present study aims to offer a corrective to traditional cliches and received wisdom about intellectual life in ancient Greece. The work proposes, and aims to reconstruct, a mental landscape in which myth and reason connect and vividly interact, and in which the concepts of mythos and logos are intertwined in the terminological network of the ancient Greek language.

The notion of a non-sensory mental state or event that plays a prominent role in coming to understand, an epistemic achievement distinct from mere knowledge, featured prominently in historical writings on philosophy, and philosophical methodology. It is, however, completely absent from contemporary discussions of the subject. This paper argues that intuition plays an epistemic role in understanding, including philosophical understanding, and offers an explanation of how intuition manages to play this role, if and when it does. It is argued, (...) subsequently, that this role is autonomous, in the sense that a source of understanding cannot be reduced to a source of justification, evidence, or reason. Finally, it is noted that such autonomy implies that popular forms of skepticism about intuition do not impugn intuition’s epistemic significance with respect to its status as a source of understanding.

Is imagination a source of knowledge? Timothy Williamson has recently argued that our imaginative capacities can yield knowledge of a variety of matters, spanning from everyday practical matters to logic and set theory. Furthermore, imagination for Williamson plays a similar epistemic role in cognitive processes that we would traditionally classify as either a priori or a posteriori, which he takes to indicate that the distinction itself is shallow and epistemologically fruitless. In this chapter, I aim to defend the (...) a priori-a posteriori distinction from Williamson’s challenge by questioning his account of imagination. I distinguish two notions of imagination at play in Williamson’s account – sensory vs. belief-like imagination – and show that both face empirical and normative issues. Sensory imagination seems neither necessary nor sufficient for knowledge. Whereas, belief-like imagination isn’t adequately disentangled from inference. Additionally, Williamson’s examples are ad hoc and don’t generalize. I conclude that Williamson’s case against the a priori-a posteriori distinction is unconvincing, and so is the thesis that imagination is an epistemic source. (shrink)

This dissertation is about a priori justification and its relationship to experiential evidence. I begin with the assumption that a priori justification is justification that is independent of experience. It has been argued that putative examples of a priori justification are implausible because they are not, in any significant sense, independent of experience. My two central claims are that (a) a subject is plausibly justified a priori in believing a proposition only if the belief is not (...) revisable on empirical grounds, which I will call the empirical unrevisability thesis; and (b) moderate rationalists can resist four empirical challenges considered by many to be decisive against the empirical unrevisability thesis. I begin by developing an account of experiential evidence that is neutral between rationalists and empiricists in order to make clear the distinction between a priori and a posteriori justification. I then argue that a moderate rationalist account of a priori justification is plausible only if the beliefs justified a priori are empirically unrevisable in a qualified sense. I then argue that four classical objections that putative cases of a priori justification are not independent of experience fail, namely, that they are revisable by some instances of contrary testimony, by mistakes in long proofs and memory, that a paradigm example of a priori knowledge was overturned by new evidence in physics, and that psychological data undermines the reliability of sources of a priori justification. I conclude that there is only one potentially threatening case, derived from neurological malfunction, and I leave the solution to this case to future research. (shrink)

This PhD thesis provides an extended evaluation of evolutionary debunking arguments in meta-ethics. Such arguments attempt to show that evolutionary theory, together with a commitment to robust moral objectivity, lead to moral scepticism: the implausible view that we lack moral knowledge or that our moral beliefs are never justified (e.g. Joyce 2006, Street 2005, Kahane 2011). To establish that, these arguments rely on certain epistemic principles. But most of the epistemic principles appealed to in the literature on evolutionary debunking (...) arguments are imprecise, confused or simply implausible. My PhD aims to rectify that. Informed by debates in cutting-edge contemporary epistemology, Chapter 1 distinguishes three general, independently motivated principles that, combined with evolution, seem to render knowledge of robustly objective moral facts problematic. These epistemic principles state that (i.) our getting facts often right in a given domain requires explanation – and if we cannot provide one, our beliefs about that domain are unjustified; (ii.) higher-order evidence of error undermines justification; and (iii.) for our beliefs to be justified, our having them must be best explained by the facts they are about. Chapters 2-4 develop and critically assess evolutionary debunking arguments based on those principles, showing that only the one inspired by (iii.) succeeds. Chapter 2 investigates the argument that evolution makes explaining why we get moral facts often right impossible. I argue that Justin Clarke-Doane’s recent response (2014, 2015, 2016, 2017) works, yet neglects an issue about epistemic luck that spells trouble for robust moral objectivity. Chapter 3 discusses the argument that evolution provides higher-order evidence of error regarding belief in robustly objective moral facts. I show that such an argument falls prey to Katia Vavova’s (2014) self-defeat objection, even if evolutionary debunkers tweak their background view on the epistemic significance of higher-order evidence. Chapter 4 develops the argument that evolution, rather than robustly objective moral facts, best explains why we hold our moral beliefs. I offer a systematic, comprehensive defence of that argument against Andreas Mogensen’s (2015) charge of explanatory levels confusion, Terrence Cuneo’s (2007) companion in guilt strategy, and David Enoch’s (2012, 2016) appeal to deliberative indispensability. Chapter 5 brings everything together. It investigates whether robust moral objectivity survives the worry about epistemic luck raised in Chapter 2 and the explanatory challenge developed in Chapter 4. Making progress, however, requires a better idea of how we form true, justified beliefs about and acquire knowledge of robustly objective moral facts. Since it offers the most popular and best-developed epistemology of robustly objective morality, my inquiry in Chapter 5 focuses on contemporary moral intuitionism: the view that moral intuitions can be the source of basic moral knowledge. I argue that its success is mixed. While moral intuitionism has the conceptual tools to tackle the problem of epistemic luck from Chapter 2, it cannot insulate knowledge of robustly objective moral facts against the sceptical worry raised by the evolutionary debunking argument developed in Chapter 4. Thus, evolutionary theory, together with a commitment to robust moral objectivity, does lead to a form of unacceptable moral scepticism. (shrink)

People increasingly form beliefs based on information gained from automatically filtered Internet ‎sources such as search engines. However, the workings of such sources are often opaque, preventing ‎subjects from knowing whether the information provided is biased or incomplete. Users’ reliance on ‎Internet technologies whose modes of operation are concealed from them raises serious concerns about ‎the justificatory status of the beliefs they end up forming. Yet it is unclear how to address these concerns ‎within standard theories of (...) class='Hi'>knowledge and justification. To shed light on the problem, we introduce a ‎novel conceptual framework that clarifies the relations between justified belief, epistemic responsibility, ‎action, and the technological resources available to a subject. We argue that justified belief is subject to ‎certain epistemic responsibilities that accompany the subject’s particular decision-taking circumstances, ‎and that one typical responsibility is to ascertain, so far as one can, whether the information upon which ‎the judgment will rest is biased or incomplete. What this responsibility comprises is partly determined by ‎the inquiry-enabling technologies available to the subject. We argue that a subject’s beliefs that are ‎formed based on Internet-filtered information are less justified than they would be if she either knew how ‎filtering worked or relied on additional sources, and that the subject may have the epistemic ‎responsibility to take measures to enhance the justificatory status of such beliefs.‎.

It is widely acknowledged that two methods of writing have emerged in the history of usūl literature: Juristic method (usūl al-fuqahā) and theological method (usūl al-mutakallimīn). Although there are some attempts to determine the typical features of these methods, we do not have a comprehensive explanation regarding the criteria of this distinction, the motivation behind it and the period when these methods have become prevalent. This paper aims to shed light to certain dimensions of the issue and focuses especially on (...) the impact of juristic disputations and khilāfiyāt on the emergence of juristic method. The discussions about the sources and methods of religious knowledge were a significant part of the heated intellectual debates in the early period of Islamic scholarships. These discussions made by scholars interested in theological matters in kalām context were the matters of usūl, which would have turned into a separate discipline thereafter. The aforementioned period also witnessed Hanafīs completing the first fiqh compilation by recording the body of masā’il in fiqh that they had developed and codified. Hanafīs then involved in the methodological discussions of theologians in the context of justifying their juristic views. The tradition of scholarly discussion that had widely contributed to the earlier period took a new dimension by the introduction of jadal to the Islamic world. First theologians and later jurists adopted the method of jadal in their debates and scholarly works. By the 4th and 5th centuries AH, fiqh became popular more than ever and promoted the juristic disputations in such a way that those disputations turned into a common and significant performance among Islamic intellectuals. Meanwhile, the khilaf genre, in which the disputed juristic matters have been discussed and justified, improved in those centuries as well. Consequently, a new method of usūl writing, namely the method of fuqahā, which can be applied in the justification of the masā’il and in juristic disputations, emerged. Thus, the first and most typical work of that method, Taqwīm al-Adilla by Dabūsī, perfectly addressed the needs of the disputation tradition in the era, by including many chapters that could be regarded as related to the substantial law and many examples from substantial law, by treating the jadal topics in qiyas and ‘illa chapters in detail and by avoiding the speculative theological disputes. Later, the method developed by Dabūsī attracted attention and many jurisprudents wrote usūl works adopting the method before the end of 5th century AH. Especially the usūl work of Bazdawī served as a model for the later Hanafī usūl literature. However, the juristic method lost its popularity when the Islamic scholarships fell under the influence of philosophy and logic after al-Gazālī and al-Rāzī. Jadal and ‘ilm al-bahth wa’l-munāzara have been treated under the discipline of logic afterwards. Nevertheless, even after the evolution of the usūl perspective, some Hanafīs still wrote usūl works by juristic method and some of them, despite adopting the new philosophical perspective, referred to the usūl of Bazdawī in their “mamzūj” (combined) usūl works.
