This paper surveys selected (though arguably representative) versions of metaphysical and epistemological disjunctivism. Although they share a common logical structure, it is hard to find a further common denominator among them. Two main conclusions are: (1) a specific standpoint on the nature of perceptual relation is not such a common denominator, which means that it is very unlikely that all of these views could be refuted with a single objection; (2) contrary to what its name suggests, disjunctivism can be correctly (...) expressed without the employment of disjunction.

Epistemological Disjunctivism is a view about paradigm cases of perceptual knowledge. Duncan Pritchard claims that it is particularly well suited to accounting for internalist and externalist intuitions. A number of authors have disputed this claim, arguing that there are problems for Pritchard’s way with internalist intuitions. I share the worry. However, I don’t think it has been expressed as effectively as it can be. My aim in this paper is to present a new way of formulating the worry, in terms (...) of an “explanatory challenge”. The explanatory challenge is a simple, yet powerful and illuminating challenge for Epistemological Disjunctivism. It is illuminating in the sense that it shows us why Epistemological Disjunctivism must take on certain internalistically problematic commitments. A secondary aim of this paper is to examine whether the recently much-discussed distinction between justifications and excuses in epistemology can support an adequate response. I will argue that it cannot. (shrink)
