Sosa’s Responses to Dreaming Skepticism
[Las respuestas de Sosa al escepticismo del sueño]

Abstract: Ernest Sosa has proposed two different ways to respond to dreaming skepticism. In this paper I argue that Sosa's first response —which centers on holding that we have no beliefs in dreams— does not appear to be successful against (what we have called) either the hyperbolic or the realistic dreaming skeptic. I also argue that his second attempt to respond to the dreaming skeptic by arguing that perceptual knowledge indeed counts as what he calls "animal knowledge", may succeed but requires us to perform what appears to be some radical surgery on the concept of knowledge; a radical surgery that, as I show, is probably unnecessary to avoid dreaming skepticism. Finally, I sketch some independent considerations why I think that the hyperbolic skeptic's dreaming argument is not acceptable.
Keywords: epistemic virtues, hyperbolic skepticism, skeptical challenge
