 By “core physical properties” I mean the properties that appearance have “in themselves” according to Kant, roughly, Lockean primary qualities (see Locke, Essay concerning Human Understanding, book II, chapter VIII). Feder-Garve accuse Kant of holding (1), which I will call “identity phenomenalism”. But even if he did not hold that extreme view, he might hold one of the weaker views listed here. Claim (2) is a quite strong form of phenomenalism, for it entails that, in some sense, all there is to objects is our representations of them, although they are not literally identical to those representation. I will call this “strong phenomenalism”. The exact meaning of Berkeley’s own views about bodies is unclear, and not the subject of this entry. But it is not implausible to read Berkeley as holding (2). However, claim (3), while very controversial and (arguably) extremely counter-intuitive, is weaker. It allows that there may be more to the existence of objects in space than our representing them, and it allows that there may be aspects or properties of objects that they possess independently of how we represent them. I will call it “qualified phenomenalism”. In discussing the debate about Kant’s alleged phenomenalism, and Kant’s own responses to the Feder-Garve review, it will help to have these distinctions in mind.
