193Knowledge and Subjunctive ConditionalsPhilosophy Compass 2 (6): 781-791. 2007.What relation must hold between a fact p and the corresponding belief that p for the belief to amount to knowledge? Many authors have recently proposed that the relation can be captured by subjunctive conditionals. In this paper I critically evaluate the main proposals along those lines

234The diagonal and the demonPhilosophical Studies 110 (3). 2002.Reliabilism about epistemic justification - the thesis that what makes a belief epistemically justified is that it was produced by a reliable process of belief-formation - must face two problems. First, what has been called "the new evil demon problem", which arises from the idea that the beliefs of victims of an evil demon are as justified as our own beliefs, although they are not - the objector claims - reliably produced. And second, the problem of diagnosing why skepticism is so appealing des…Read more

564Perceptual reasonsPhilosophical Studies 173 (4): 991-1006. 2016.The two main theories of perceptual reasons in contemporary epistemology can be called Phenomenalism and Factualism. According to Phenomenalism, perceptual reasons are facts about experiences conceived of as phenomenal states, i.e., states individuated by phenomenal character, by what it’s like to be in them. According to Factualism, perceptual reasons are instead facts about the external objects perceived. The main problem with Factualism is that it struggles with bad cases: cases where perceiv…Read more

6Escepticismo semántico y teorías del significadoAnálisis Filosófico 18 (2): 143-149. 1998.In several works H. Putnam has developed an argument addressed against "realist" semantic theories (in particular, against causal theories of reference ). In this paper I argue that Putnam's argument is weaker than what is generally supposed, as Devitt has shown in Realism and Truth. I disagree, however, with Devitfs latest strategy against model-theoretic arguments as presented in an ''Afterword'' to that book.

150Could there be exactly two things?Synthese 162 (1). 2008.Many philosophers think that, necessarily, any material objects have a fusion (let’s call that doctrine “Universalism”). In this paper I point out a couple of strange consequences of Universalism and related doctrines, and suggest that they are strange enough to constitute a powerful argument against those views

756Is Evidence of Evidence Evidence?Noûs 51 (1): 95-112. 2017.We examine whether the "evidence of evidence is evidence" principle is true. We distinguish several different versions of the principle and evaluate recent attacks on some of those versions. We argue that, whatever the merits of those attacks, they leave the more important rendition of the principle untouched. That version is, however, also subject to new kinds of counterexamples. We end by suggesting how to formulate a better version of the principle that takes into account those new counterexa…Read more

399Normative Requirements and Contrary-to-Duty ObligationsJournal of Philosophy 112 (11): 600-626. 2015.I argue that normative requirements should be interpreted as the conditional obligations of dyadic deontic logic. Semantically, normative requirements are conditionals understood as restrictors, the prevailing view of conditionals in linguistics. This means that Modus Ponens is invalid, even when the premises are known

425Easy Knowledge Makes No Difference: Reply to WielenbergLogos and Episteme 6 (2). 2015.We have recently proposed a diagnosis of what goes wrong in cases of ‘easy-knowledge.’ Erik Wielenberg argues that there are cases of easy knowledge thatour proposal cannot handle. In this note we reply to Wielenberg, arguing that our proposal does indeed handle his cases.

81Conciliation and Peer-Demotion in the Epistemology of DisagreementAmerican Philosophical Quarterly 49 (3): 237-252. 2012.What should your reaction be when you find out that someone that you consider an "epistemic peer" disagrees with you? Two broad approaches to this question have gained support from different philosophers. Precise characterizations of these approaches will be given later, but consider for now the following approximations. First, there is the "conciliatory" approach, according to which the right reaction to a disagreement is to move one's opinion towards that of one's peer, in proportion to the de…Read more

313Unsafe KnowledgeSynthese 146 (3): 395-404. 2005.Ernest Sosa has argued that if someone knows that p, then his belief that p is “safe”. and Timothy Williamson has agreed. In this paper I argue that safety, as defined by Sosa, is not a necessary condition on knowledge – that we can have unsafe knowledge. I present Sosa’s definition of safety and a counterexample to it as a necessary condition on knowledge. I also argue that Sosa’s most recent refinements to the notion of safety don’t help him to avoid the counterexample. I consider three replie…Read more

1162Williamson on Gettier Cases and Epistemic LogicInquiry: An Interdisciplinary Journal of Philosophy 56 (1): 15-29. 2013.Timothy Williamson has fruitfully exploited formal resources to shed considerable light on the nature of knowledge. In the paper under examination, Williamson turns his attention to Gettier cases, showing how they can be motivated formally. At the same time, he disparages the kind of justification he thinks gives rise to these cases. He favors instead his own notion of justification for which Gettier cases cannot arise. We take issue both with his disparagement of the kind of justification that …Read more

405Evidence of evidence is evidenceAnalysis 75 (4): 557-559. 2015.Richard Feldman has proposed and defended different versions of a principle about evidence. In slogan form, the principle holds that ‘evidence of evidence is evidence’. Recently, Branden Fitelson has argued that Feldman’s preferred rendition of the principle falls pray to a counterexample related to the non-transitivity of the evidence-for relation. Feldman replies arguing that Fitelson’s case does not really represent a counterexample to the principle. In this note, we argue that Feldman’s prin…Read more
