Can perceptual experiences be states of uncertainty? We might expect them to be, if the perceptual processes from which they are generated, and the behaviors they help produce, take account of probabilistic information. Yet, it has long been presumed that perceptual experiences purport to tell us about our environment, without hedging or qualifying. Against this long-standing view, I argue that perceptual experiences may well occasionally be states of uncertainty, but that they are never probabilistically structured. I criticize a powerful line of reasoning that we should expect perceptual experience to be probabilistic, given their interfaces with unconscious probabilistic information, with behavior responsive to it, and with credences.

知觉经验如何解释不确定性？

知觉体验可以是不确定的状态吗？如果产生它们的感知过程以及它们帮助产生的行为考虑概率信息，我们可能会期望它们。然而，长期以来，人们一直认为感知体验旨在告诉我们我们的环境，而不是对冲或限定。与这种长期存在的观点相反，我认为感性体验可能偶尔会是不确定的状态，但它们永远不是概率结构的。我批评了一种强有力的推理，即我们应该期望知觉体验是概率性的，因为它们与无意识的概率信息、对它作出反应的行为以及可信度的接口。
