I objected that the defeasibility theory of knowledge prohibits you from knowing that you know that p if your knowledge that p is a posteriori. Rodrigo Borges claims that Peter Klein has already satisfactorily answered a version of my objection. He attempts to defend Klein’s reply and argues that my objection fails because a principle on which it is based is false.I will show that my objection is not a version of the old one that Klein (...) attempts (unsuccessfully) to address, that Borges’ defence of Klein’s reply fails and that his argument against my new objection leaves it untouched.

This is a very selective survey of developments in epistemology, concentrating on work from the past twenty years that is of interest to philosophers of science. The selection is organized around interesting connections between distinct themes. I first connect issues about skepticism to issues about the reliability of belief-acquiring processes. Next I connect discussions of the defeasibility of reasons for belief to accounts of the theory-independence of evidence. Then I connect doubts about Bayesian epistemology to issues about the (...) content of perception. The last detailed connection is between considerations of the finiteness of cognition and epistemic virtues. To connect the connections I end by briefly discussing the pressure that consideration of social roles in the transmission of belief puts on the purposes of epistemology. (shrink)

I argue that recent rationalists' accounts of a priori knowledge suffer from two substantial weaknesses: an inadequate phenomenology of a priori insight , and the error of psychologism. I show that Husserl's theory of a priori knowledge presents a defensible and viable alternative for the contemporary rationalist, an alternative that addresses both the ontology and phenomenology of rational intuition, as well as such contemporary concerns as the possibility and character of a priori error, the empirical defeasibility (...) of a priori claims, the relation of mind to necessity, and the role of conception and imagination in a priori knowledge. Consequently, I conclude that Husserl's theory provides the needed response to the 20 th century critique of rationalism, and its attendant a priorism, as mysterious and obscure. (shrink)

According to the Reasoning View about normative reasons, facts about normative reasons for action can be understood in terms of facts about the norms of practical reasoning. I argue that this view is subject to an overlooked class of counterexamples, familiar from debates about Subjectivist theories of normative reasons. Strikingly, the standard strategy Subjectivists have used to respond to this problem cannot be adapted to the Reasoning View. I think there is a solution to this problem, however. I argue that (...) the norms of practical reasoning, like the norms of theoretical reasoning, are characteristically defeasible, in a sense I make precise. Recognizing this property of those norms makes space for a solution to the problem. The resulting view is in a way analogous to the familiar defeasibility theory of knowledge, but it avoids a standard objection to that theory. (shrink)

In some recent work, John N.Williams defends a new objection to the defeasibility theory of knowledge. But the objection is of wider interest, since Williams also suggests that this style of objection may undermine other theories of knowledge. I distinguish two versions of Williams’ objection. I then show that the first version relies on false conceptual principles, and the second relies on a specific and dubious conception of the goal of the analysis of knowledge.

A growing number of authors defend putative examples of knowledge from falsehood (KFF), inferential knowledge based in a critical or essential way on false premises, and they argue that KFF has important implications for many areas of epistemology (whether evidence can be false, the Gettier debate, defeasibility theories of knowledge, etc.). I argue, however, that there is no KFF, because in any supposed example either the falsehood does not contribute to the knowledge or the subject (...) lacks knowledge. In particular, I show that if the subject actually has knowledge in putative KFF cases, then there is always a veridical evidential path meeting the basing conditions that accounts for her knowledge; if there is no such path, then the subject is in a type of Gettier case. All the recent arguments that rely on KFF are therefore based on a mistake. (shrink)

Drawing on the puzzling behavior of ordinary knowledge ascriptions that embed an epistemic (im)possibility claim, we tentatively conclude that it is untenable to jointly endorse (i) an unfettered classical logic for epistemic language, (ii) the general veridicality of knowledge ascription, and (iii) an intuitive ‘negative transparency’ thesis that reduces knowledge of a simple negated ‘might’ claim to an epistemic claim without modal content. We motivate a strategic trade-off: preserve veridicality and (generalized) negative transparency, while abandoning the general (...) validity of contraposition. We criticize various approaches to incorporating veridicality into domain semantics, a paradigmatic ‘information-sensitive’ framework for capturing negative transparency and, more generally, the non-classical behavior of sentences with epistemic modals. We then present a novel information-sensitive semantics that successfully executes our favored strategy: stable acceptance semantics, extending a vanilla bilateral state-based semantics for epistemic modals with a knowledge operator loosely inspired by the defeasibility theory of knowledge.

How, if at all, is knowing how to do something defeasible? Some, the “intellectualists”, treat the defeasibility of knowledge-how as in some way derivative on the defeasibility of knowledge-that. According to a recent proposal by Carter and Navarro (Philos Phenomenol Res 3:662–685, 2017), knowledge-how defeat cannot be explained in terms of knowledge-that defeat; instead, knowledge-how defeat merits and entirely separate treatment. The thought behind “separatism” is easy to articulate. Assuming that knowledge of (...) any kind is defeasible, since knowledge-that and knowledge-how are fundamentally different beasts, the best accounts of their defeasibility must reflect the underlying differences between them. I reject a separatist treatment of the defeasibility of knowledge-that and knowledge-how. One can acknowledge certain important differences between knowledge-that and knowledge-how without thereby needing two theories of defeasibility. Ultimately, though, I’ll argue that the defeasibility of basic knowledge-how, unlike non-basic knowledge-how, is a much more difficult issue than has been acknowledged. (shrink)

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)

John N. Williams argued that Peter Klein's defeasibility theory of knowledge excludes the possibility of one knowing that one has (first-order) a posteriori knowledge. He does that by way of adding a new twist to an objection Klein himself answered more than forty years ago. In this paper I argue that Williams' objection misses its target because of this new twist.

The central question of this article is how to combine counterfactual theories of knowledge with the notion of actuality. It is argued that the straightforward combination of these two elements leads to problems, viz. the problem of easy knowledge and the problem of missing knowledge. In other words, there is overgeneration of knowledge and there is undergeneration of knowledge. The combination of these problems cannot be solved by appealing to methods by which beliefs are formed. (...) An alternative solution is put forward. The key is to rethink the closeness relation that is at the heart of counterfactual theories of knowledge. (shrink)

A recursive definition of knowledge is proposed, to deal with Gettier style difficulties, and provide a framework for a variety of recursionist theories of knowledge.

The Gettier Problem is the problem of revising the view that knowledge is justified true belief in a way that is immune to Gettier counter-examples. The “Gettier Problem problem”, according to Lycan, is the problem of saying what is misguided about trying to solve the Gettier Problem. In this paper I take up the Gettier Problem problem. I distinguish giving conditions that are necessary and sufficient for knowledge from giving conditions that explain why one knows when one does (...) know. I argue that the problem with the Gettier Problem is that it requires us to articulate conditions that suffice for knowledge even if those conditions are non-explanatory. After defending this view, I take up two related methodological issues, one about the evidence that can be given in favor of an account of knowledge, and one about the role that investigating justification might play in investigating knowledge.

In this dissertation I present a new solution to the renowned Gettier problem. My solution, which in a sense represents a defense of a rather traditional epistemological approach, is based upon a distinction between primary and secondary beliefs. I argue that primary beliefs are known if justified and true, whereas secondary beliefs are known if they are believed on the basis of a known primary belief. Much emphasis is put upon defending this approach against potential objections, but I also draw (...) some epistemological and semantical consequences pertaining to such issues as the nature of epistemological justification, the Lottery Paradox, philosophical skepticism and the semantics of belief contexts.

Here is a definition of knowledge: for you to know a proposition p is for you to have an outright belief in p that is correct precisely because it manifests the virtue of rationality. This definition resembles Ernest Sosa’s “virtue theory”, except that on this definition, the only virtue that must be manifested in all instances of knowledge is rationality, and no reductive account of rationality is attempted—rationality is assumed to be an irreducibly normative notion. This definition (...) is compatible with “internalism” about rationality, and with a form of “pragmatic encroachment” on the conditions of rational outright belief. An interpretation is given of this definition, and especially of the sense of ’because’ that it involves. On this interpretation, this definition entails that both safety and adherence are necessary conditions on knowledge; it supports a kind of contextualism about terms like ‘knowledge’; and it provides resources to defend safety, adherence, and contextualism, against some recent objections.

A theory of knowledge is the explanation of things in terms of the possibilities and capabilities of the human way of knowing. The human knowledge is the representation of the things apprehended sensitively either through the senses or intuition. A theory of knowledge concludes about the reality of the things studied. As such it is a priori speculation, based on synthetic a priori statements. Its conclusions constitute interpretation, that is, hermeneutics. Linguistics as the science studying (...) real language, that is, the language spoken, reverts to human subjects in as much as they speak, say and know. Language thus must be studied as a theory of knowledge. (shrink)

Is knowledge consistent with literally any credence in the relevant proposition, including credence 0? Of course not. But is credence 0 the only credence in p that entails that you don’t know that p? Knowledge entails belief (most epistemologists think), and it’s impossible to believe that p while having credence 0 in p. Is it true that, for every value of ‘x,’ if it’s impossible to know that p while having credence x in p, this is simply because (...) it’s impossible to believe that p while having credence x in p? If so, is it possible to believe that p while having (say) credence 0.4 in p? These questions aren’t standard epistemological fare, at least in part because many epistemologists think their answers are obvious, but they have unanticipated consequences for epistemology. Let ‘improbabilism’ name the thesis that it’s possible to know that p while having a credence in p below 0.5. Improbabilism will strike many epistemologists as absurd, but careful reflection on these questions reveals that, if improbabilism is false, then all of the most plausible theories of knowledge are also false. Or so I argue in this paper. Since improbabilism is widely rejected by epistemologists (at least implicitly), this paper reveals a tension between all of the most plausible theories of knowledge and a widespread assumption in epistemology.

A brief dissertation on what knowledge is.

A short dissertation on a definition for knowledge. Although similar to binary opposition, this treatise follows the logic to conclude that knowledge is finite.

Sophocles’ Oedipus the King is an extended meditation on the limits of human intelligence, or more precisely, on how a man renowned for the power of his intellect could fail to know the most important truths. One could argue, however, that Sophocles intended for his audiences to take away a second, narrower lesson: namely that divinely inspired seers such as Tiresias have a surer claim on truth than do those who, like Oedipus, seek to gain knowledge through their own (...) efforts. Thus, the Oedipus can be seen as a defense of prophecy and a reaction against the complex of scientific and philosophical ideas known as “the 5th-century Enlightenment.” I offer some support for this reading of the Oedipus. I also argue that part of the cultural background of the Oedipus consisted of ideas about knowledge introduced into Greek thought by the outspoken critic of Greek popular religion, Xenophanes of Colophon.

An account of Plato’s theory of knowledge is offered. Plato is in a sense a contextualist: at least, he recognizes that his own use of the word for “knowledge” varies – in some contexts, it stands for the fullest possible level of understanding of a truth, while in other contexts, it is broader and includes less complete levels of understanding as well. But for Plato, all knowledge, properly speaking, is a priori knowledge of necessary truths (...) – based on recollection of aspects of the Forms – and so in contemporary terms, it meets the conditions of “safety” and “adherence” (or “indefeasibility”) to the highest degree. This account is defended on the basis of the text of Meno, Phaedo, and the Republic, against some objections – especially objections that are due to Gail Fine. (shrink)

Skepticism about the external world may very well be correct, so the question is in order: what theory of knowledge flows from skepticism itself? The skeptic can give a relatively simple and intuitive account of knowledge by identifying it with indubitable certainty. Our everyday ‘I know that p’ claims, which typically are part of practical projects, deploy the ideal of knowledge to make assertions closely related to, but weaker than, knowledge claims. The truth of such (...) claims is consistent with skepticism; various other vexing problems don’t arise. In addition, even if no claim about the world outside my mind can be more probable than its negation, the project of pure scientific research remains well motivated. (shrink)

The concept of knowledge (science) plays a central role in the work of early modern proto-feminist philosopher Gabrielle Suchon. Nevertheless, there has been no comprehensive treatment of her epistemology. This article offers the first extended analysis of Suchon’s theory of knowledge and describes the role of that theory in her arguments for the equality of men and women. I argue that Suchon combines an Aristotelian theory of knowledge and its place in the best life (...) of contemplation with an Augustinian narrative of the Fall to conclude that women's happiness is unjustly compromised as a result of their exclusion from the very institutions that would allow them to accomplish an essentially human task: the reparative labor of learning. I argue further that Suchon’s theory of knowledge deserves greater attention as a distinctive contribution to early modern epistemology. Suchon’s melding of Aristotelian epistemology with an Augustinian narrative of the epistemic consequences of original sin allows her to construe intellectual labor as key to the rectification of the fallen human mind. Through this emphasis on the moral value of intellectual labor, Suchon’s epistemology offers distinctive social and political implications, namely the reform of institutions that exclude women from the process of learning.

Reductive intellectualists (e.g., Stanley & Williamson 2001; Stanley 2011a; 2011b; Brogaard 2008; 2009; 2011) hold that knowledge-how is a kind of knowledge-that. If this thesis is correct, then we should expect the defeasibility conditions for knowledge-how and knowledge-that to be uniform—viz., that the mechanisms of epistemic defeat which undermine propositional knowledge will be equally capable of imperilling knowledge-how. The goal of this paper is twofold: first, against intellectualism, we will show that knowledge-how (...) is in fact resilient to being undermined by the very kinds of traditional (propositional) epistemic defeaters which clearly defeat the items of propositional knowledge which intellectualists identify with knowledge-how. Second, we aim to fill an important lacuna in the contemporary debate, which is to develop an alternative way in which epistemic defeat for knowledge-how could be modelled within an anti-intellectualist framework.

Hans Kleinpeter provided a popularization of both Ernst Mach's thought and the scientific philosophy that forerun the foundation of the Vienna Circle. Between 1912 and 1913 Kleinpeter published the articles that one finds here in their first Italian translation; they concern a comparison between Mach's epistemology and Nietzsche's thought, and are thus an original contribution to the reception of the latter's philosophy. In these texts Kleinpeter anticipates some of the ideas he later presented in his work devoted to the 'Phenomenalistic' (...) worldview, whose - according to him - Nietzsche has been one of the main upholders, as much as Mach.

Most epistemologists agree that epistemic justification is required for knowledge. This requirement is usually formulated in one of two ways: S knows that p only if S is justified in believing that p. S knows that p only if S's belief that p is justified. Surprisingly and are generally regarded as synonymous formulations of the justification condition. In Chapter 1, I argue that such a synonymy thesis is mistaken and that, in fact, and specify substantively different requirements. requires that (...) the person be justified, whereas requires that the belief in question be justified, and intuitively, these constitute different requirements. Thus, it is concluded that and employ inherently different kinds of epistemic justification in their respective analysantia. I dub them "personal justification" and "doxastic justification", respectively. The remainder of the dissertation is devoted to demonstrating both the legitimacy and the importance of the personal/doxastic justification distinction. For example, the distinction helps account for the divergent intuitions that regularly arise regarding justificatory evaluations in demon-world contexts. ;In Chapters 2 and 3 I provide analyses for doxastic and personal justification. Chapter 2 spells out an externalist reliabilist account of doxastic justification which safely avoids demon-world counterexamples. Chapter 3 advances an internalist coherence account of personal justification. In defending this coherence theory, I argue that all foundation theories are false and that the regress argument on which they are predicated is unsound. ;In Chapter 4, I propose an analysis of ordinary knowledge which only requires doxastic justification. Nevertheless personal justification plays a negative, undermining role in the analysis. I then demonstrate that this analysis of knowledge is immune to typical Gettier examples. It also remains unscathed by Harman's beefed-up Gettier cases. Finally, I consider a stronger analysis of knowledge requiring both doxastic and personal justification. Though the latter analysis proves too strong for ordinary knowledge, it remains interesting as an analysis of a more intellectualistic kind of knowledge. ;The final chapter examines the internalist/externalist controversy and demonstrates that this controversy is yet another manifestation of the personal/doxastic justification conflation.

Rachael Briggs and Daniel Nolan attempt to improve on Nozick’s tracking theory of knowledge by providing a modified, dispositional tracking theory. The dispositional theory, however, faces more problems than those previously noted by John Turri. First, it is not simply that satisfaction of the theory’s conditions is unnecessary for knowledge – it is insufficient as well. Second, in one important respect, the dispositional theory is a step backwards relative to the original tracking (...) class='Hi'>theory: the original but not the dispositional theory can avoid Gettier-style counterexamples. Future attempts to improve the tracking theory would be wise to bear these problems in mind. (shrink)

In a recent paper, Tristan Haze offers two examples that, he claims, are counterexamples to Nozick's Theory of Knowledge. Haze claims his examples work against Nozick's theory understood as relativized to belief forming methods M. We believe that they fail to be counterexamples to Nozick's theory. Since he aims the examples at tracking theories generally, we will also explain why they are not counterexamples to Dretske's Conclusive Reasons Theory of Knowledge.

A philosophical study of the nature, types and conditions of knowledge, namely belief, truth, and justification. It discusses the most prominent theories presented by contemporary philosophers in the analysis of these conditions. It answers questions related to understanding, interpretation and scientific knowledge.

Moreover, the author addresses the concepts of knowledge through linguistic and logical analysis. He defends a vision of philosophy as (...) a conceptual clarification as well as a natural tendency.

Abstract In this paper I present a short outline of an Indicativity Theory of Knowledge, for the cases of Perceptual Knowledge and Knowledge by Memory. I explain the main rationale for a token-indicativity approach, and how it is fleshed out precisely in terms of chances. I elaborate on the account of the value of knowledge it provides, and what that value is. I explain why, given the rationale of conceiving Knowledge as token indicativity, separate (...) sub-accounts in terms of chances should be extracted for the different modes of Knowledge, elaborating on the common core of high token-indicativity. In the main section that outlines the account of Perceptual Knowledge, the main Indicativity condition is presented, as are the main condition of in what sense high token indicativity should yields high chance, the important Discriminability condition, and its associated Contrast Class.

In this paper we argue that knowledge is characteristically safe true belief. We argue that an adequate approach to epistemic luck must not be indexed to methods of belief formation, but rather to explanations for belief. This shift is problematic for several prominent approaches to the theory of knowledge, including virtue reliabilism and proper functionalism (as normally conceived). The view that knowledge is characteristically safe true belief is better able to accommodate the shift in question.

We propose a solution to the problem of logical omniscience in what we take to be its fundamental version: as concerning arbitrary agents and the knowledge attitude per se. Our logic of knowledge is a spin-off from a general theory of thick content, whereby the content of a sentence has two components: an intension, taking care of truth conditions; and a topic, taking care of subject matter. We present a list of plausible logical validities and invalidities for (...) the logic of knowledge per se for arbitrary agents, and isolate three explanatory factors for them: the topic-sensitivity of content; the fragmentation of knowledge states; the defeasibility of knowledge acquisition. We then present a novel dynamic epistemic logic that yields precisely the desired validities and invalidities, for which we provide expressivity and completeness results. We contrast this with related systems and address possible objections. (shrink)

According to the laudative theory of knowledge, “knowledge” is a mere laudative term—a term, such as “athletic,” “artistic,” or “masterpiece,” that expresses merely that some entity is good relative to some domain. (I.e., the laudative theory claims that for you to know some proposition just is for you to believe some true proposition in a good way.) I defend the laudative theory by contrasting inferential knowledge and memory. A central component of what it is (...) for an inferential belief to constitute knowledge is that the subject’s belief being true is due to the subject’s competent reasoning, rather than due to luck (i.e., inferential knowledge is incompatible with veritic luck). Conversely, I argue that many instances of successful memory are accurate due to luck, and that many such instances of successful memory nonetheless constitute (or provide a basis for) knowledge. If so, then there is some feature that is a central component of what it is for an inferential belief to constitute knowledge, but that is not even necessary for a memory (or memory-based belief) to constitute knowledge; and this fact suggests that, rather than picking out a substantive, unitary phenomenon, “knowledge” is a mere laudative term.

Anyone familiar with Russell’s work on the multiple-relation theory of judgment will at some point have puzzled over the map of the five-term understanding complex at the end of Chapter 1, Part II of his Theory of Knowledge (1913). Russell presents the map with the intention of clarifying what goes on when a subject S understands the “proposition” that A and B are similar. But the map raises more questions than it answers. In this paper I present (...) and develop some of the central issues that arise from Russell’s map, and I offer an interpretation of it that reflects his evolving views in the manuscript. I argue that multiple lines in the map are not meant to represent many relations, but rather one comprehensive multiple relation of understanding. And I argue that such a relation relates in a complex way due to the distinctive nature of its relata. (shrink)

In this paper, we use concepts, structure and tools from argumentation theory to show how conversational implicatures are triggered by conflicts of presumptions. Presumptive implicatures are shown to be based on defeasible forms of inference used in conditions of lack of knowledge, including analogical reasoning, inference to the best explanation, practical reasoning, appeal to pity, and argument from cause. Such inferences are modelled as communicative strategies to knowledge gaps that shift the burden of providing the missing contrary (...) evidence to the other party in a dialogue. Through a series of illustrative examples, we show how such principles of inference are based on common knowledge about the ordinary course of events shared by participants in a structured dialogue setting in which they take turns putting forward and responding to speech acts.

We will argue here, that one of the salient messages of standard quantum formalism implies a failure of Classical Theory of Knowledge (hereafter CTK) which is primarily based on the presumption that, our knowledge is predetermined by Nature. This failure provides pointers against the classically held ontological definiteness of future. Quantum formalism admits interpretation , that suggests, that there is no such thing as ‘universal global present’ in the sense of being able to confirm a complete set (...) of facts of matter about it, unless this is coupled with a specific observation recipe.

Kant mentions two faculties of the mind that are involved in the knowing process, namely, sensibility and understanding. Through the former, the objects are “given” while through the latter, objects are “thought of.” The receiving faculty, that of sensibility, deals with space and time as pure intuitions. On the other, the thinking faculty - that of understanding, treats concepts or categories. Thus, these faculties of the human reason presuppose the two elements of knowledge: contents or intuitions and thoughts or (...) concepts for sensibility and understanding, respectively. This paper aims at presenting the coming-to-be of knowledge through the operations of the mind in Kant’s Critique of Pure Reason and critically exposes the correlation of sensibility and of understanding in the knowing process.

This dissertation engages in a critical analysis of the work of Adolf Reinach in the theory of knowledge and legal philosophy. Reinach had trained as a lawyer and brought that perspective and experience to bear in his phenomenological work on problems in evidence and legal philosophy. His contributions to phenomenology in the early 20th century provide a window into the earliest phases of the development of the phenomenological movement, prior to World War I. This dissertation locates this work (...) in the European intellectual context of the era and finds analogies with key philosophical dilemmas and developments in England during the same period, arguably ones with shared intellectual roots. Valued for his talent as an inspiring university lecturer, Reinach was a central figure in the circle of young scholars who practiced phenomenology in the spirit of the "early" "pre-Ideen" phase of phenomenology. The dissertation Appendices include translations of selected excerpts from the Nachlass. My translation of the obituary Edmund Husserl wrote and published following Adolf Reinach's death in WWI is published separately. Professor Raymond Klibansky was my supervisor and mentor throughout.

The present article is an attempt to give - in the frame of the theory of the organism - environment system - a new interpretation to the role of efferent influences on receptor activity and to the functions of senses in the formation of knowledge. It is argued, on the basis of experimental evidence and theoretical considerations, that the senses are not transmitters of environmental information, but they create a direct connection between the organism and the environment, which (...) makes the development of a dynamic living system, the organism - environment system, possible. In this connection process the efferent influences on receptor activity are of particular significance, because with their help the receptors may be adjusted in relation to the parts of the environment which are most important in the achievement of behavioral results. Perception is the process of joining of new parts of the environment to the organism - environment system ; thus, the formation of knowledge by perception is based on reorganization of the organism - environment system, and not on transmission of information from the environment. With the help of the efferent influences on receptors each organism creates its own peculiar world which is simultaneously subjective and objective. The present considerations have far reaching influences as well on experimental work in neurophysiology and psychology of perception as on philosophical considerations of knowledge formation.

I will discuss a variety of cases such that the subject's believing truly is somewhat of an accident, but less so than in a Gettier case. In each case, this is because her reasons are not ultimately undefeated full stop, but they are ultimately undefeated with certain qualifications. For example, the subject's reasons might be ultimately defeated considered in themselves but ultimately undefeated considered as a proper part of an inference to the best explanation that is undefeated without qualification. In (...) each section of the paper, I consider different qualifications and show how in each case we get an epistemic standing I call “coach-class knowledge”. First-class knowledge requires justifying reasons that are undefeated without qualification. Coach-class knowledge only requires qualified lack of defeat. I will use this distinction to bring debates over knowledge from falsehood and fake barns to an ecumenical resolution. In both cases, the subject enjoys coach-class rather than first-class knowledge. I will also show that the defeasible reasoning tradition can better account for graded accidental truth than safety theories. (shrink)

I present two counterexamples to the recently back-in-favour truth-tracking account of knowledge: one involving a true belief resting on a counterfactually robust delusion, one involving a true belief acquired alongside a bunch of false beliefs. These counterexamples carry over to a recent modification of the theory due to Briggs and Nolan (2012), and seem invulnerable to a recent defence of the theory against known counterexamples, by Adams and Clarke (2005).

This article discusses a kind of knowledge classifiable as knowledge-wh but which seems to defy analysis in terms of the standard reductive theory of knowledge-wh ascriptions, according to which they are true if and only if one knows that p, where this proposition is an acceptable answer to the wh-question ‘embedded’ in the ascription. Specifically, it is argued that certain cases of knowing what an experience is like resist such treatment. I argue that in some of (...) these cases, one can know that p, where an acceptable answer to the question ‘What’s the experience like?’ is that p, but where one does not know what the experience is like. This could point to the distinctiveness of this sort of knowledge. (shrink)

Alvin Plantinga’s theory of knowledge, as developed in his Warrant trilogy, has shaped the debates surrounding many areas in epistemology in profound ways. Plantinga has received his share of criticism, however, particularly in his treatment of belief in God as being “properly basic”. There has also been much confusion surrounding his notions of warrant and proper function, to which Plantinga has responded numerous times. Many critics remain unsatisfied, while others have developed alternative understandings of warrant in order to (...) rescue Plantinga’s theory from certain objections. The most promising of such attempts fall under the broad category of “virtue epistemology” or a “virtue-theoretic” approach. The work being done in virtue epistemology is still in its early stages and a consensus on what actually constitutes virtue epistemology has yet to be reached. While some have attempted to structure an entire theory of knowledge based on the virtues possessed by the knower, others have focused more on the role of epistemic virtues as an attempt to supplement existing theories, including Plantinga’s. In this paper, I will offer an analysis of what such an attempt might look like and evaluate the potential success of broadening Plantinga’s original model. -/- My proposal is that certain features of a virtue-theoretic approach (also referred to as “agent-reliabilism”) could improve Plantinga’s model in significant ways. Not only would such a broadened approach be better equipped to handle common objections, but it would also be better suited to contribute an enhanced understanding of the task of epistemology, one that seeks to discover multiple epistemic goods other than what has been traditionally confined to the realm of knowledge. I conclude by applying this approach to Plantinga’s treatment of theistic belief in Warranted Christian Belief and by articulating a few of the ways in which epistemic virtues can increase the degree of warrant enjoyed by such belief.

Consider the claims that representations of physical laws are intersubjective, and that they ultimately provide the foundation for all other intersubjective knowledge. Those claims, as well as the deeper philosophical commitments that justify them, constitute rare points of agreement between the Marburg School neo-Kantians Paul Natorp and Ernst Cassirer and their positivist rival, Ernst Mach. This is surprising, since Natorp and Cassirer are both often at pains to distinguish their theories of natural scientific knowledge from positivist views like (...) Mach’s, and often from Mach’s views in particular. Thus the very fact of this agreement between the Marburg School neo-Kantians and their positivist stalking horse points to a deep current of ideas that runs beneath the whole of the post-Kantian intellectual context they shared.

Presently, we have no language or any communication system to describe them intelligibly. When inquiring about these affairs we cannot avoid absurdity as presently we lack any linguistic convention on it. Our linguistic convention is derived from the physical world in which the supernatural is not considered as "Normal". It is considerably strained with "Abnormality" in the first place. My aim in this paper is to reconcile this Orthodox Psychology with Science and Philosophy which certainly appears conflicting. This inquiry leads me to enable the 10 percent brain myth. (shrink)

Argument that Marx has a realist ontology and a correspondence theory of truth. His views are compared to both Hegel's and Kant's. This interpretation departs from more Hegelian, 'idealist' interpretations that often rely on misunderstanding some of the work of the early Marx. There is also a discussion and partial defence of Lenin's Materialism and Empirio-Criticism.

Bernard Lonergan has argued for a theory of cognition that is transcendentally secure, that is, one such that any plausible attempt to refute it must presuppose its correctness, and one that also grounds a correct metaphysics and ontology. His proposal combines an identity theory of knowledge with an intentional relation between knower and known. It depends in a crucial way upon an appropriation of one’s own cognitional motives and acts, that is, upon “knowing one’s own knowing.” I (...) argue that because of conflicts between the identity and intentionality components of the theory, rational self-appropriation cannot, as Lonergan claims, be an iteration of just the same acts by which we acquire other sorts of knowledge. I propose an amended theory in which the relation between intending-subject and intended-object of first-level cognition becomes, in RSA, a numerical identity of knower and known and of the epistemic and the ontological.
