 The qualified phenomenalist also owes us an answer to the question, which are the representations whose content partly grounds the existence of empirical objects and wholly grounds their core physical properties? The natural answer is “experience”, so the qualified phenomenalist owes us an interpretation of what Kant means by “experience”, what its content is, and how it grounds (partly) the existence and (wholly) empirical properties of  appearances.[27]  We have already seen that, for familiar reasons, Kant cannot ground the existence of empirical objects in our mere perceptions of them: sometimes we misperceive objects, objects exist while unperceived, and there are objects we cannot ever directly perceive.
