 Cook Wilson’s influence is also evident in Prichard’s argument against Kant’s view that we cannot know things in themselves, but only know them as they present themselves, or appear, to us. Prichard inherits from Cook Wilson the view that any state of mind that affects the nature of its presentations cannot be knowledge. Knowledge can only be of what it does not affect; its object must be entirely independent. In Kant’s terms, then, the only possible objects of knowledge are things in themselves. Appearances, assuming that they are objects, cannot be known at all, but must be the object of some other state of mind.
