 But this is not the plain meaning of the relevant passages. At A371 Kant claims that appearances are a species (Art) of representations; while “is” can be interpreted in a number of ways (e.g., the “is” of constitution), it is hard to interpret “As are a species of Bs” in any other way than: every A is a B, which means every A is identical to a B (namely, itself). While there may be something to the “grounding” interpretation of these passages, there are good reasons to think these texts have not been explained (or explained away).
