Much of present-day epistemology is divided between internalists and externalists. Different as these views are, they have in common that they strip justification from its dialectical component in order to block the skeptic’s argument from disagreement. That is, they allow that one may have justified beliefs even if one is not able to defend it against challenges and resolve the disagreements about them. Lammenranta (2008, 2011a) recently argued that neither internalism nor externalism convinces if we consider the argument in its (...) most interesting format. In this paper I zoom in on this debate, and fix further details of Lammenranta’s lead. Specifically, I will side with skepticism that justification is dialectical, yet only if certain conditions are in place. (shrink)

The internalism /externalism debate is of interest in epistemology since it addresses one of the most fundamental questions in the discipline: what is the basic nature of knowledge and epistemic justification? It is generally held that if a positive epistemic status obtains, this is not a brute fact. Rather if a belief is, for example, justified, it is justified in virtue of some further condition obtaining. What has been called epistemic internalism holds, as the label suggests, is that all the (...) relevant factors that determine justification must be “internal”. Epistemic externalism is the denial of internalism. Epistemic internalism about justification is the subject of this article. After introducing the central intuitive considerations that have tended to motivate internalism, this paper will explore different ways of construing the internalist position. In addition to classical formulations, more recent formulations will be discussed, concluding with a discussion of an emerging position known as “Epistemological Disjunctivism”, which its advocates claim preserves the most important features of more traditional forms of internalism, while avoiding their difficulties. Epistemological Disjunctivism is particularly worthy of attention since if true, it promises to bridge internalist and externalist epistemologies, bringing a rapprochement to two sides of what may otherwise appear a deep and intractable debate about the fundamental nature of epistemology.

Epistemological disjunctivism (ED) has been thought to solve the conditionality problem for epistemic externalism. This problem arises from externalists’ characterization of our epistemic standings as conditional on the obtaining of worldly facts which we lack any reflective access to. ED is meant to avoid the conditionality problem by explicating subjects’ perceptual knowledge in paradigmatic cases of perceptual knowledge via their possession of perceptual reasons that are both factive and reflectively accessible. I argue that ED’s account of reflectively accessible factive perceptual (...) reasons is also prey to the conditionality problem. After that, I submit that Stroud’s influential formulation of the conditionality problem relies on a methodological requirement that is potentially dissociable from ED. So, it is possible to put ED in the service of a more modest anti-skeptical strategy. I close by suggesting that this modest anti-skeptical strategy successfully undercuts the underdetermination-based skeptical paradox. Nevertheless, it does not have substantial advantages over some forms of epistemic externalism. (shrink)

This paper defends the view that, in certain actual circumstances that aren’t uncommon for educated westerners, an awareness of the facts of religious disagreement doesn’t make theistic belief irrational. The first section makes some general remarks about when discovering disagreement (on any topic) makes it rational to give up your beliefs: it discusses the two main possible outcomes of disagreement (i.e., defeat of one’s disputed belief and demotion of one’s disputant), the main kinds of evidence that are relevant to demoting (...) one’s disputant, and the kinds of epistemic assessment involved in demoting a disputant. The second section argues that in cases of disagreement about theism, the theist’s evidence for theism and for the reliability of her theistic belief is often strong enough to support steadfastness in the face of disagreement. The third section argues that the theist’s evidence for the reliability of her disputant’s atheistic beliefs is often weak enough to allow her to rationally demote her atheist interlocutor and it explains how this demotion can occur in a sensible and appropriate way. The final section focuses on theists whose disagreement-based doubts about theism persist, despite the defenses offered on behalf of theism against such doubts. It concludes that these persistent doubts could in some cases result in defeaters for theistic belief, even if the doubts are irrational, but that the gift of faith can compensate for this. (shrink)

This dissertation examines the way Philip Melanchthon, author of the Augsburg Confession and Martin Luther's closest co-worker, sought to establish the relationship between faith and reason in the cradle of the Lutheran tradition, Wittenberg University. While Melanchthon is widely recognized to have played a crucial role in the Reformation of the Church in the sixteenth century as well as in the Renaissance in Northern Europe, he has in general received relatively little scholarly attention, few have attempted to explore his philosophy (...) in depth, and those who have examined his philosophical work have come to contradictory or less than helpful conclusions about it. He has been regarded as an Aristotelian, a Platonist, a philosophical eclectic, and as having been torn between Renaissance humanism and Evangelical theology. An understanding of the way Melanchthon related faith and reason awaits a well-founded and accurate account of his philosophy. Having stated the problem and finding it inadequately treated in the secondary literature, this dissertation presents an account of Melanchthon's philosophical development. Finding that his philosophy was ultimately founded upon his understanding of and method in rhetoric and dialectics, this dissertation explicates his mature accounts of these arts. It then presents an account of Melanchthon's philosophy as both humanistic (i.e., rhetorically based and practically rather than speculatively oriented) and fideistic (i.e, skeptical about the product of human reason alone, but finding certainty in philosophy founded upon, and somewhat limited by, Christian faith). After a final assessment of claims about Melanchthon's philosophy from the secondary literature, this dissertation considers how such a humanistic, fideistic philosophy might be helpful for Christians in a philosophically post-modern situation.

The epistemological problem of the external world asks: (1) “How is knowledge of the external world possible given certain obstacles which make it look impossible?” This is a “how-possible?” question: it asks how something is possible given certain obstacles which make it look impossible (cf. Cassam 2007; Nozick 1981; Stroud 1984). Now consider the following question, which asks: (2) “How is a philosophically satisfying answer to (1) possible?” Skepticism is the thesis that knowledge of the external world is impossible. It (...) therefore represents a negative answer to the first question. Meta-epistemological skepticism is the thesis that a satisfying philosophical explanation of how our knowledge of the external world is possible is itself impossible. It therefore represents a negative answer to the second question. In this thesis, I explore the prospects of meta-epistemological skepticism. In particular, I structure the thesis around two master arguments from for meta-epistemological skepticism. The first argument is that skepticism represents a kind of paradox which requires dispensing with a plausible principle or belief, or even 'platitude', which means that there's no philosophically satisfying response to the paradox (see, e.g., Stroud 1984), and the second argument is “Stroud’s dilemma” (cf. Cassam 2009), that either we explain how external world knowledge is possible by reference to what external world knowledge we have, thereby failing to answer the philosophical question adequately, or else we don't, but then we succumb to first-order skepticism. I argue that the first argument fails to provide adequate support for meta-epistemological skepticism. However, the second argument, Stroud’s dilemma, is plausible and withstands serious objections (e.g., from Sosa 1994, Williams 1996, and Cassam 2009). In short, while the worry emerging out of the 'skeptical paradox' view fails to adequately support meta-epistemological skepticism, Stroud’s dilemma succeeds. Fortunately, it doesn't show that we lack external world knowledge; we rather just can't explain, philosophically, how it's possible. We may have first-order knowledge without understanding how it's possible. This thesis therefore represents a partial defense of meta-epistemological skepticism. Meta-epistemological skepticism is a live option in epistemology. (shrink)

The dissertation examines the nature and epistemic implications of epistemic source circularity. An argument exhibits this type of circularity when at least one of the premises is produced by a belief source the conclusion says is legitimate, e.g. a track record argument for the legitimacy of sense perception that uses premises produced by sense perception. In chapter one I examine this and several other types of circularity, identifying relevant similarities and differences between them. In chapter two I discuss the differences (...) between internalist and externalist analyses of justification. I examine in detail foundationalist and non-foundationalist versions of internalism, and go on to consider how one might characterize externalism: either negatively, by denying particular internalist theses, or positively, in terms of a theory offering different conditions for justification. I discuss the views of reliabilist foundationalists at length. In chapter three I present the internalist objection to externalism that the latter mistakenly permit one to be justified in believing the conclusion of an epistemic source circular inference. I explain the externalists' response that it is not in virtue of their externalism that they permit epistemic source circularity but rather their foundationalism; thus, internalist foundationalists must permit epistemic source circularity as well. I evaluate the positions of several internalists, most of them explicitly foundationalists, and argue that they too cannot avoid permitting epistemic source circularity. In the final chapter I consider whether such circularity is vicious, even though both internalist and externalist foundationalists permit it. I argue that one can sustain an objection to epistemic source circularity by imposing a non-question-begging requirement on justification and explain how respecting this requirement leads one to a non-foundationalist view. I conclude by considering the objection that question-begging leads to a certain arbitrariness in belief formation that should give the foundationalist pause when it comes to determining, at the beginning of inquiry, which beliefs are justified and which are not. The dissertation is primarily concerned with making clear the possible skeptical and non-skeptical positions one can take towards epistemic source circularity. I do not argue for the truth of a particular metaepistemology. (shrink)

In this dissertation I consider the problem of external world skepticism and attempts at providing an argument to the best explanation against it. In chapter one I consider several different ways of formulating the crucial skeptical argument, settling on an argument that centers on the question of whether we're justified in believing propositions about the external world. I then consider and reject several options for getting around this issue which I take to be inadequate. I finally conclude that the best (...) option available to us at the moment is to argue that the antiskeptical view is the best explanation of our ordinary experiences In chapter two I argue that, if we hope to ground what counts as defending antiskepticism in common sense, there is an argument against the possibility of ever knowing one has succeeded in defending antiskepticism. After showing that common sense is no place to look in setting a goal for our antiskeptical project, I present the view that what will be crucial to settling on our antiskeptical goal is coming to a successful analysis of the nature of physical objects. I suggest some minimal criteria that must be met by a view in order to be antiskeptical based on our intuitions about core skeptical cases, but acknowledge that a fully successful response to external world skepticism will require the antiskeptic to engage in some much more difficult analysis. In chapter three I consider various views of the nature of explanation and conclude, tentatively, that explanation as it interests the antiskeptic is fundamentally causal. In chapter four I consider and reject some of the core views on which best explanation facts are so fundamental that a project of attempting to vindicate probabilistically the virtues which make explanations epistemically good. In this chapter I show that views which analyze justification in terms of best explanation factors fail. In chapter five I attempt to vindicate the various explanatory virtues probabilistically. In doing so I attempt to express or translate the various explanatory virtues in terms of probabilities in order to show that having those virtues makes a view at least prima facie more probable. In chapters six and seven I explain and evaluate the various arguments to the best explanation against skepticism present in current philosophical literature. I attempt to show that extant arguments fail to appreciate the virtues possessed by classical skeptical scenarios. In chapter eight I briefly consider some options that may be open to the antiskeptic moving forward. All routes forward contain considerable obstacles, but there are some fruitful areas of research to pursue. (shrink)
