Abstract

Justin D’Ambrosio and I have recently and independently defended perceptual adverbialism from Frank Jackson’s well-known Many-Properties Problem. Both of us make use of a similar strategy: characterizing ways of perceiving by using the language of objects, and not just of properties. But while D’Ambrosio’s view does indeed validate the inferences that Jackson’s challenge highlights, it does so at the price of validating additional, invalid inferences, such as the inference from the claim that a small child hallucinates a bottle of aspirin to the claim that the child hallucinates a bottle of acetylsalicylic acid. My view avoids this. The crucial difference is that D’Ambrosio appeals to success conditions, which are extensional, while I appeal to informational content, which is not.
