Skepticism is both a historical and foundational problem in epistemology. Jonathan Schaffer (2010) has provided a new expression of its threat. The Debasing Demon appears to generate a novel form of radical doubt, one that has gained prominence in recent debates. Instead of targeting the connection between belief and truth, it undercuts the link between belief and evidence (or reasons). This contribution presents the Debasing Demon Problem, analyzing its reach. It will provide an account for explaining how its threat is (...) raised, explore its relationship to classical varieties of skepticism, and assess some of the main objections against it. It will be argued that Schaffer’s Demon institutes a consistent epistemic threat, one that might represent the main variety of skepticism to be tackled in epistemology. Some consequences of this analysis are then presented concerning how to face this open problem. (shrink)

The aim of this paper is to analyse and develop how scepticism becomes an intelligible question starting from requirements that epistemologists themselves aim to endorse. We argue for and defend the idea that the root of scepticism is the underdetermination principle by articulating its specificitya respectable epistemic principle and by defending it against objections in current literature. This engagement offers a novel understanding of underdetermination-based scepticism. While most anti-sceptical approaches challenge scepticism by understanding it as postulating uneliminated scenarios of mass (...) deception, or as endorsing unnatural epistemic requirements, we argue here that both contentions are mistaken. Underdetermination-based scepticism targets our beliefs by issuing a genuine question about the rational support they enjoy. If we cannot establish that the sources of our beliefs provide them the required epistemic merit and authority, they lack non-arbitrary grounds. This has a sizable impact on what constitutes a satisfactory anti-sceptical strategy. Strategies that merely focus on the scenario-based aspect of scepticism, or on the truth-functional evaluation of our beliefs, are shown to miss the mark of the sceptical threat. The proposed analysis ultimately provides a shift in perspective concerning the character and reach of philosophical doubt. (shrink)

Epistemologists understand radical skepticism as arising from two principles: Closure and Underdetermination. Both possess intuitive prima facie support for their endorsement. Understanding how they engender skepticism is crucial for any reasonable anti-skeptical attempt. The contemporary discussion has focused on elucidating the relationship between them to ascertain whether they establish distinct skeptical questions and which of the two constitutes the ultimately fundamental threat. Major contributions to this debate are due to Brueckner, Cohen, and Pritchard. This contribution aims at defending Brueckner’s contention (...) that underdetermination expresses the fundamental skeptical threat and that the closure-based argument can ultimately be reduced to it, at least concerning skeptical contexts. This will be achieved by undermining Cohen’s objections to Brueckner on both counts. Cohen’s argument endorses a picture of evidential underdetermination, which, while apt for non-skeptical contexts, cannot be applied to radical skepticism. A comparison with a case of scientific underdetermination is developed to argue for this idea. Our argument is then applied to the principle equivalence issue and to objections against it. It is then shown how this analysis possesses a distinctive effect on our understanding of the skeptical threat and the assessment of successful anti-skeptical strategies. (shrink)

The following contribution aims at presenting a reading of Wittgenstein’s later philosophy as a kind of idealism within the Kantian and post-Kantian traditions. The goal is to argue that Wittgenstein’s position shares substantial theoretical and methodological grounds with Hegel’s idealism. The main concepts pertaining to the later Wittgenstein’s position are analyzed and understood as a form of idealism. After defending the reading against anti-idealist interpretations we argue that the kind of idealism presented clashes with central tenets of the Kantian position. (...) These points of departure are then shown to cover in a substantial manner the same kind of criticism Hegel raised against Kant. In the last section, an interpretation of central concepts of the Hegelian position is offered in order to dissolve any fundamental incompatibility with Wittgenstein’s idealism. (shrink)

Cartesian skepticism requires scenarios of massive deception to make its case. The inability to rule out such possibilities in which our beliefs about the external world are massively mistaken motivates the conclusion that we lack everyday knowledge. Some authors have emphasized that such scenarios are implausible. Others have instead claimed that scenarios are irrelevant to skepticism. If skepticism can make its case, they argue that scenarios of massive deception are not the way to do it. This thesis possesses a distinct (...) anti-sceptical weight. Deprived of its scenario, epistemological skepticism must find a different reason for it to be taken seriously, which might be a tall order. This paper defends the idea that scenarios do not constitute the essential element of the skeptical threat. However, it takes this result in the opposite direction. We aim to show that skepticism without scenarios constitutes a bigger and more legitimate philosophical problem than otherwise. Additionally, it also offers the possibility of achieving a unified understanding of skepticism that is so far lacking in contemporary epistemology, allowing us to better understand what can constitute a satisfactory anti-skeptical strategy.
