It is commonly thought that we depend fundamentally on the “evidence of the senses” for our empicial beliefs, including and most directly, our beliefs about our local environment, the spatial world around us. The ultimate evidence we have for our perceptual beliefs is provided in some way by perception or perceptual experience. But what is this evidence? There seem to be three main options: external factualism allows that the evidence include facts about the external world; internal factualism takes facts that (...) involve only the internal, mental world—like facts about one’s perceptual experiences or appearances—to count as one’s perceptual evidence; and non-factualism takes propositions, including false ones, to count as evidence—for example, propositional contents of appearances or seemings. We shall see that all these options face significant challenges. Some might conclude that perceptual beliefs can be justified without depending on evidence. Others might choose to accept skepticism: our perceptual beliefs are not justified. I shall end, however, by tentatively suggesting that there is a sort of internal fact that is a plausible candidate for perceptual evidence that has been overlooked. (shrink)

BonJour affirme qu’il a trouvé un moyen de sortir du dilemme sellarsien de la justification non-doxastique. Dans cet article, je soutiens trois thèses afin de montrer que sa solution alléguée échoue. Tout d’abord, il y a deux exigences pour qu’une raison soit bonne, et la notion de prise de conscience non-conceptuelle de l’expérience sensorielle développée par BonJour donne lieu à un dilemme sérieux en ce qui concerne ces exigences. Deuxièmement, il tire son idée de la soi-disant «prise de conscience constitutive (...) du contenu» de sa conception de la croyance consciente et occurrente. Mais cette conception conduit à un dilemme analogue à l’égard de ces exigences. Troisièmement, son explication se heurte au problème de la représentation. (shrink)

The concept of evidence is among the central concerns of epistemology broadly construed. As such, it has long engaged the intellectual energies of both philosophers of science and epistemologists of a more traditional variety. Here I briefly survey some of the more important ideas to have emerged from this tradition of reflection. I then look somewhat more closely at an issue that has recently come to the fore, largely as a result of Williamson's Knowledge and Its Limits: that of whether (...) one's evidence supervenes on one's non-factive mental states.
