Logical theories for representing knowledge are often plagued by the so-called Logical Omniscience Problem. The problem stems from the clash between the desire to model rational agents, which should be capable of simple logical inferences, and the fact that any logical inference, however complex, almost inevitably consists of inference steps that are simple enough. This contradiction points to the fruitlessness of trying to solve the Logical Omniscience Problem qualitatively if the rationality of agents is to be maintained. We provide a (...) |

Philosophers commonly define knowledge as justified true beliefs. A heated debate exists, however, about what makes a belief justified. In this article, we examine the question of belief justification from a psychological perspective, focusing on the subjective confidence in a belief that the person has just formed. Participants decided whether to accept or reject a proposition depicting a social belief, and indicated their confidence in their choice. The task was repeated six times, and choice latency was measured. The results were (...) |

La definición estándar del conocimiento intenta concebir el conocimiento proposicional como una creencia verdadera y justificada, y, con su modo de proceder, genera una serie de graves problemas. En respuesta a esto, este ensayo investiga un modelo interpretativo prometedor y alternativo del conocimiento como estructura o sistema que se acopla a las reflexiones de Nelson Goodman. A partir de una amplia base constituida por la teoría de los símbolos, es posible desarrollar un concepto de conocimiento plural y procesal que se (...) |

Philip Kitcher recently argued for a reconstruction in philosophy. According to him, the contemporary mainstream of philosophy has deteriorated into something that is of relevance only to a few specialists who communicate with each other in a language nobody else understands. Kitcher proposes to reconstruct philosophy along two axes: a knowledge axis and a value axis. The present article discusses Kitcher's diagnosis as well as his proposal of a therapy. It argues that there are problems with both, and it ends (...) |

The Gettier Problem (henceforth GP) is a milestone in contemporary epistemology. Half a century after the philosophical earthquake caused by the well-known Gettier article (1963), solutions continue to appear and the discussion resurfaces. Because we, like many, choose to adopt an optimistic stance towards the possibility of finding a plausible answer to the GP, in this paper we present an unconventional solution to solve it. Crucially, we argue that the only plausible and non-falsifiable definition of the propositional knowledge is the (...) |

Recent semantic research has made increasing use of a principle, Maximize Presupposition, which requires that under certain circumstances the strongest possible presupposition be marked. This principle is generally taken to be irreducible to standard Gricean reasoning because the forms that are in competition have the same assertive content. We suggest, however, that Maximize Presupposition might be reducible to the theory of scalar implicatures. (i)First, we consider a special case: the speaker utters a sentence with a presupposition p which is not (...) |

This essay discusses Wittgenstein’s suggestion that we may speak of a distinction between a word’s primary and secondary senses. Instead of seeing the distinction merely as an example of a puzzling language use, many commentators have attempted to work out the distinction in terms of a supplement to a general theory of sense that they presume Wittgenstein developed in his later writings. I don’t think it is fair to ascribe such systematic aspirations to Wittgenstein.Indeed, Wittgenstein speaks explicitly of the distinction (...) |

Traditional epistemological reflection on our beliefs about the world attempts to proceed without presupposing or ineliminably depending upon any claims about the world. It has been argued that epistemological externalism fails to engage in the right way with the motivations for this project. I argue, however, that epistemological externalism satisfyingly undermines this project. If we accept the thesis that certain conditions other than the truth of one's belief must obtain in the world outside of one's mind in order for one (...) |

Argues inter alia that Kant and Hegel identified necessary conditions for the possibility of singular cognitive reference that incorporate avant la lettre Evans’ (1975) analysis of identity and predication, that Kant’s and Hegel’s semantics of singular cognitive reference are crucial to McDowell’s account of singular thoughts, and that McDowell has neglected (to the detriment of his own view) these conditions and their central roles in Kant’s and in Hegel’s theories of knowledge. > Reprinted in: J. Lindgaard, ed., John McDowell: Experience, (...) |

Wilcox proposed an argument against imprecise probabilities and for the principle of indifference based on a thought experiment where he argues that it is very intuitive to feel that one’s confidence in drawing a ball of a given colour out of an unknown urn should decrease while the number of potential colours in the urn increases. In my response to him, I argue that one’s intuitions may be unreliable because it is very hard to truly feel completely ignorant in such (...) |

According to Lehrer’s defeasibility account of knowledge, we can understand knowledge as undefeated justified true belief. But this account faces many serious problems. One important problem is that from one’s subjective point of view, one can hardly bridge the gap between one’s personal justification and objective truth. Another important problem is that this account can hardly accommodate the externalist intuition that the epistemic status of a belief is not entirely determined by factors that are internal to the subject’s perspective. The (...) |

E. J. Lowe offers an account of modal knowledge that involves two primary theses. First, the basis of modal knowledge is essential knowledge, and the source of essential knowledge is grasp of essence. Second, all empirical knowledge ultimately depends on some modal knowledge. This article assesses Lowe’s account and defends four conclusions. First, there is a tension in Lowe’s account of grasp of essence; it wavers between an undemanding version, which holds that grasp of essence requires no more than our (...) |

RESUMO Ernest Sosa é um dos mais importantes filósofos da contemporaneidade. Em plena atividade há mais de cinco décadas, sua obra toma agora a forma de uma teoria da normatividade télica, com a qual Sosa pretende coroar sua procura por uma "knowledgefriendly epistemology". Pretendemos mostrar que esta nova forma teórica instala-se bem no conjunto de sua reflexão epistemológica, procurando Sosa agora, de modo ainda mais preciso, dar resposta, por exemplo, às questões decorrentes do problema de Gettier, da intencionalidade e das (...) |

O tema deste artigo é o papel do autoconhecimento na vida cognitiva de um sujeito que mereça ser considerado possuidor de conhecimento. A ideia central é que é difícil alcançar o conhecimento de si, pois a introspecção é uma fonte de crenças pouco confiável, e a razão pode ser a fonte de formas extremas de autoengano. Apesar disso, a nossa situação é tal que um agente epistêmico responsável deve buscar constantemente uma melhor compreensão dos seus próprios traços de caráter e (...) |

This paper investigates a limitation of the model of belief and knowledge prevailing in mainstream economics, namely the state-space model. Because of its set-theoretic nature, this model has difficulties in capturing the difference between expressions that designate the same object but have different meanings, i.e., expressions with the same extension but different intensions. This limitation generates puzzling results concerning what individuals believe or know about the world as well as what individuals believe or know about what other individuals believe or (...) |

ABSTRACTIki is the key word of Shūzō Kuki’s The Structure of Iki, and it became one of the most widely recognized Japanese aesthetic categories mainly due to this work. However, in The Problems of Contingency, which is Kuki’s most important philosophical work, there is no discussion of iki again, and consequently, most commentators of Kuki fail to see the correlation between his theories of iki and contingency. This article, by contrast, intends to provide a new interpretation of iki in the (...) |

Hegel has been widely, though erroneously, supposed to have rejected epistemology in favor of unbridled metaphysical speculation. Reputation notwithstanding, Hegel was a very sophisticated epistemologist, whose views have gone unrecognized because they are so innovative, indeed prescient. Hence I shall boldly state: Hegel's epistemology is of great contemporary importance. In part, this is because many problems now current in epistemology are problems Hegel addressed. In part, this is because of the unexpected effectiveness of Russell's 1922 exhortation, “I should take ‘back (...) |

According to a historical claim oft-repeated by contemporary epistemologists, the ‘traditional’ conception of knowledge prevailed in Western philosophy prior to the publication in 1963 of Edmund’s Gettier’s famous three-page article ‘Is Justified True Belief Knowledge?’. On this conception, knowledge consists of justified true belief. In this article, I critically consider evidence for and against this historical claim, and conclude with a puzzle concerning its widespread acceptance. |

This paper revisits a puzzle that arises for theories of knowledge according to which one can know on the basis of merely inductive grounds. No matter how strong such theories require inductive grounds to be if a belief based on them is to qualify as knowledge, there are certain beliefs (namely, about the outcome of fair lotteries) that are based on even stronger inductive grounds, while, intuitively, they do not qualify as knowledge. This paper discusses what is often regarded as (...) |

Materialism—the view that all of reality is wholly determined by the very, very small—and extreme nominalism—the view that properties, kinds, and qualities do not really exist—have been the dominant view in analytic philosophy for the last 100 years or so. Both views, however, have failed to provide adequate accounts for the possibility of intentionality and of knowledge. We must therefore look to alternatives. One well-tested alternative, the hylomorphism of Aristotle and the medieval scholastics, was rejected without being refuted and so (...) |

Beginning with Zagzebski (The Philosophical Quarterly 44:65–73, 1994), some philosophers have argued that there can be no solution to the Gettier counterexamples within the framework of a fallibilist theory of knowledge. If true, this would be devastating, since it is believed on good grounds that infallibilism leads to scepticism. But I argue here that these purported proofs are mistaken and that the truthmaker solution to the Gettier problems is both cogent and fallibilist in nature. To show this I develop the (...) |

The paper outlines an epistemic logic based on the proof theory of substructural logics. The logic is a formal model of belief that i) is based on true assumptions (BTA belief) and ii) does not suffer from the usual omniscience properties. |

This paper raises questions about the epistemological foundations of evidence-based medicine . We argue that EBM is based upon reliabilist epistemological assumptions, and that this is appropriate - we should focus on identifying the most reliable processes for generating and collecting medical knowledge. However, we note that this should not be reduced to narrow questions about which research methodologies are the best for gathering evidence. Reliable processes for generating medical evidence might lie outside of formal research methods. We also question (...) |

Knowing is something that we do not have much of a theory about., p. 365.)Interest has recently been shown in causal theories of perception, memory, inference, reference, truth, justification and belief, as well as in a more general “causal theory of knowledge” which would embrace and connect all of these concepts within a broad epistemological framework. The burden of this paper is that prospects are poor for an interesting and general enough causal theory of knowledge. A threat to generality arises (...) |

This paper defends a simple, externalist account of knowledge, incorporating familiar conditions mentioned in the literature, and responds to Timothy Williamson’s charge that any such analysis is futile because knowledge is semantically un-analyzable. The response, in short, is that even though such an account may not offer a reductive analysis of knowledge-by way of more basic, non-circular concepts-it still has an explanatory advantage over Williamson’s own position: it explains how belief can fail to be knowledge. |

In Tracking Truth I undertook a broader project than is typical today toward questions about knowledge, evidence, and scientific realism. The range of knowledge phenomena is much wider than the kind of homely examples—such as ‘‘She has a bee in her bonnet’’—that are often the fare in discussions of knowledge. Scientists have knowledge gained in sophisticated and deliberate ways, and non-human animals have reflexive and rudimentary epistemic achievements that we can easily slip into calling ‘‘knowledge.’’ What is it about knowledge (...) |

Robert Almeder has argued1 that three “fourth conditions” for nondefectiveness of knowledge justification claims, proposed in the recent literature,2 are essentially similar, require modification in order to eliminate the possibility of an unknowable defeater, and, so modified, render attainment of non-basic factual knowledge impossible. Although I believe there are objections to be raised against his exposition and reduction of the three proposed fourth conditions, I wish only to raise some doubts about the supposed necessity of the modifications and then to (...) |

The Generality Problem for process reliabilism is to outline a procedure for determining when two beliefs are produced by the same process, in such a way as to avoid, on the one hand, individuating process types so narrowly that each type is instantiated only once, or, on the other hand, individuating them so broadly that beliefs that have different epistemic statuses are subsumed under the same process type. In this paper, I offer a solution to the problem which takes belief‐independent (...) |

As a result of his studies in metalogicEssler became convincedthat an absolute fixed totality of alltruths and a final metalanguage doesnot exist. Taking this result into account,it is shown that the usualabsolute concept of omniscience isuntenable. From this it can be concludedthat definitions of knowledge whichappeal to such a concept of omnisciencelead to serious problems. |

In this paper I discuss the relation between various properties that have been regarded as important for determining whether or not a belief constitutes a piece of knowledge: its stability, strength and sensitivity to truth, as well as the strength of the epistemic position in which the subject is with respect to this belief. Attempts to explicate the relevant concepts more formally with the help of systems of spheres of possible worlds (à la Lewis and Grove) must take care to (...) |

What features of structural injustice distinguish it from mere collections of injustices committed by individuals? I argue that the standard model of moral judgment that centers agents and actions fails to adequately articulate what’s gone wrong in cases of structural injustice. It fails because features of the social world that arise only at large scale are normatively salient, but unaccounted for by the standard model. I illustrate these features with historical examples of normatively-different outcomes driven by institutional structure rather, holding (...) |

A novel solution is offered for how emotional experiences can function as sources of immediate prima facie justification for evaluative beliefs, and in such a way that suffices to halt a justificatory regress. Key to this solution is the recognition of two distinct kinds of emotional skill and how these must be working in tandem when emotional experience plays such a justificatory role. The paper has two main parts, the first negative and the second positive. The negative part criticises the (...) |

This paper develops a normative account of epistemic luck, according to which the luckiness of epistemic luck is analyzed in terms of the expectations a subject is entitled to have when she satisfies the standards of epistemic justification. This account enables us to distinguish three types of epistemic luck—bad, good, and sheer—and to model the roles they play e.g. in Gettierization. One controversial aspect of the proposed account is that it is non‐reductive. While other approaches analyze epistemic luck in non‐epistemic (...) |
