Descartes’ demon is a deceiver: the demon makes things appear to you other than as they really are. However, as Descartes famously pointed out in the Second Meditation, not all knowledge is imperilled by this kind of deception. You still know you are a thinking thing. Perhaps, though, there is a more virulent demon in epistemic hell, one from which none of our knowledge is safe. Jonathan Schaffer (2010) thinks so. The “Debasing Demon” he imagines threatens knowledge not via the truth condition on knowledge, but via the basing condition. This demon can cause any belief to seem like it’s held on a good basis, when it’s really held on a bad basis. Several recent critics (Brueckner (2011), Conee (2015), Ballantyne & Evans (2013)) grant Schaffer the possibility of such a debasing demon, and argue that the skeptical conclusion doesn’t follow. By contrast, we argue that on any plausible account of the epistemic basing relation, the “debasing demon” is impossible. Our argument for why this is so gestures, more generally, to the importance of avoiding common traps by embracing mistaken assumptions about what it takes for a belief to be based on a reason.

This article is about the epistemic basing relation, which is the relation that obtains between beliefs and the reasons for which they are held. We need an adequate account of the basing relation if we want to have a satisfactory account of doxastic justification, which we should want to have. To that end, this article aims to achieve two goals. The first is to show that a plausible account of the basing relation must invoke counterfactual concepts. The second is to set out two related analyses of the basing relation, each of which seems quite plausible.

Roderick Chisholm argues that in giving an account of knowledge, we must either begin with an account of what knowledge is, and proceed on that basis to identify the particular things that we know, or else start with instances of knowledge, and proceed on that basis to formulate a definition of knowledge. Either approach begs the question against the other. This is the epistemic wheel. This article responds to Chisholm's challenge. It begins with cases of knowledge attribution and builds its account from there, identifying those features that we take to be present in the cases where we have attributed knowledge and those features that seem important when we want to withhold an attribution of knowledge. The proposal does not beg the question against either particularists or methodists; it takes the best features of each view, without beginning with either, and thereby removes us from the wheel.

One finds a surprising number of defenses of the legitimacy of some kinds of question-begging arguments or beliefs in the literature. Without wanting to deny the importance of dialectical analyses of begging the question, what I do here is explore the epistemic side of the issue. In particular, I want to explore the legitimacy of “epistemically circular” arguments and beliefs. My tentative conclusion is that epistemically circular arguments and beliefs are never legitimate. *Note: this is an unpublished manuscript presented at the 2011 conference of the Ontario Society for the Study of Argumentation. A copy of the manuscript is hosted at the OSSA conference archive, linked above. Some of the central ideas in this paper appear in my "Epistemic Circularity, Reliabilism, and Transmission Failure," Episteme (2014).

It has been claimed that there is a lottery paradox for justification and an analogous paradox for knowledge, and that these two paradoxes should have a common solution. I argue that there is in fact no lottery paradox for knowledge, since that version of the paradox has a demonstrably false premise. The solution to the justification paradox is to deny closure of justification under conjunction. I present a principle which allows us to deny closure of justification under conjunction in certain kinds of cases, but which still allows that belief in a conjunction on the basis of justified belief in its conjuncts can often be justified.
