 At Level 1, the adverbialist rejects the Phenomenal Principle and the whole idea that experience consists in being directly presented with perceptible entities. For the adverbialist, when someone has an experience of something white, something like whiteness is instantiated, but in the experience itself, not a presented thing. This is not to say that the experience is white, but rather that the experience is modified in a certain way, the way we can call “perceiving whitely”. The canonical descriptions of perceptual experiences, then, employ adverbial modifications of the perceptual verbs: instead of describing an experience as someone’s “visually sensing a white sphere”, the theory says that they are “visually sensing whitely and spherely”. This is why this theory is called the “adverbial theory”; but it is important to emphasize that it is more a theory about the nature of experience itself than it is a semantic analysis of sentences describing experience.
