Saul Kripke argued that the requirement that knowledge eliminate all possibilities of error leads to dogmatism . According to this view, the dogmatism puzzle arises because of a requirement on knowledge that is too strong. The paper argues that dogmatism can be avoided even if we hold on to the strong requirement on knowledge. I show how the argument for dogmatism can be blocked and I argue that the only other approach to the puzzle in the literature is mistaken.

I propose and defend the conjecture that what explains why Gettiered subjects fail to know is the fact that their justified true belief depends essentially on unknown propositions. The conjecture follows from the plausible principle about inference in general according to which one knows the conclusion of one’s inference only if one knows all the premises it involves essentially.

The 'Gettier Problem' has been central to epistemology since 1963, when Edmund Gettier presented a powerful challenge to the standard analysis of knowledge. Now twenty-six leading philosophers examine the issues that arise from Gettier's challenge, setting the agenda for future work on the central problem of epistemology.

John N. Williams argued that Peter Klein's defeasibility theory of knowledge excludes the possibility of one knowing that one has 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.

This is a collection of new essays written in honor of the work of Peter D. Klein, who has had and continues to have a tremendous influence in the development of epistemology. The essays reflect the breadth and depth of Klein’s work by engaging directly with his views and with the views of his interlocutors.

The paper introduces a new problem for fallibilist and infallibilist epistemologies – the diachronic threshold problem. As the name suggests, this is a problem similar to the well–known threshold problem for fallibilism. The new problem affects both fallibilism and infallibilism, however. The paper argues that anyone who worries about the well known problem for fallibilism should also worry about this new, diachronic version of the problem.

The Gettier Problem and Moore’s Paradox are related in a way that is unappreciated by philosophers. If one is in a Gettier situation, then one is also in a Moorean situation. The fact that S is in a Gettier situation (the fact that S is “Gettiered”), like the fact that S is in a Moorean situation (the fact that S is “Moored”), cannot (in the logical sense of “cannot”) be known by S while S is in that situation. The paper (...) starts the job of mapping what can be said about this feature of Gettier situations. The goal is to stimulate further exploration into this yet uncharted territory. (shrink)

Anti-luck epistemologists tell us that knowledge is incompatible with epistemic luck and that epistemic luck is just a special case of luck in general. Much work has been done on the intricacies of the first claim. In this paper, I scrutinize the second claim. I argue that it does not survive scrutiny. I then offer an analysis of luck that explains the relevant data and avoids the problems from which the current views of luck suffer. However, this analysis of luck (...) is of no help to the anti-luck epistemologist for it uses knowledge to explain luck, making this account of knowledge circular. The main lesson is that the only viable analysis of luck is not suited for the anti-luck epistemologist's coveted noncircular analysis of knowledge. (shrink)

ABSTRACT This book symposium features three critical pieces dealing with Duncan Pritchard's book, 'Epistemic Angst'; the symposium also contains Pritchard's replies to his critics.

A direct implication of E=K seems to be that false beliefs cannot justify other beliefs, for no false belief can be part of one’s total evidence and one’s total evidence is what inferentially justifies belief. The problem with this alleged implication of E=K, as Comesaña and Kantin :447–454, 2010) have noted, is that it contradicts a claim Gettier cases rely on. The original Gettier cases relied on two principles: that justification is closed under known entailment, and that sometimes one is (...) justified in believing a falsehood. In this paper I argue that E=K, contrary to what Comesaña and Kantin would want us to believe, is compatible with the agent being justified in believing a falsehood. (shrink)

Este texto revisa las principales aportaciones de Walter Lippmann contenidas en su obra Libertad y prensa, de reciente aparición en lengua castellana. Publicado originalmente en 1920, el libro de Lippmann nos permite conocer sus agudas reflexiones acerca de las relaciones entre medios de comunicación, opinión pública y clase política. El estudio de esas relaciones ocupa una parte fundamental de la obra ensayística de Lippmann, cuya vigencia y vitalidad permanecen hoy inalteradas. Lippmann no fue sólo el columnista político más influyente del (...) pasado siglo, sino un penetrante analista que se interroga sobre la objetividad informativa, la deficiente formación de los profesionales de la prensa y su discutible fibra moral. Sus observaciones trascienden el restringido mundo de los medios de comunicación para preguntarse si su funcionamiento deficiente no pone en cuestión la supervivencia misma de la democracia.

De acordo com Jennifer Lackey, deve-se asserir que p somente se é razoável acreditar que p e se alguém asseriu que p, afirmaria que p pelo menos em parte porque é razoável acreditar que p. Como dados para essa norma de asserção, Lackey apela à intuição de que, nos casos de afirmação altruísta, os agentes afirmam com propriedade epistêmica algo que não acreditam. Se essa norma de afirmação fosse verdadeira, então ela explicaria por que as afirmações altruístas são epistemicamente apropriadas. (...) Neste trabalho, oferecemos uma reductio ad absurdum desse ponto de vista. O resultado é que os asserções altruístas não são epistemicamente apropriados. (shrink)

Taking into account a survey made by Madrid Press Association among journa-lists and users of mass media, this article discusses the positions expressed by Carlos Ruíz (2008) and Hugo Aznar (2009) about the role that Ethics and Law play as a means to supervise the behaviour of mass media nowadays. Firstly, we will try to argue about the necessity of complementing the concept of journalism of classical liberalism with the contributions made by the so called social responsibility theory. Secondly, we (...) will show some of the limits of Law as a means of control of journalism practice and will defend the values and contributions of ethical reflection. Finally, we will point out the conditions that journalistic self- regulation must satisfy to act as a credible tool for regulation. (shrink)
