 One main source of the phenomenalist reading is the A Edition “Fourth Paralogism”, in which Kant refutes the “Cartesian” view that our inner states are immediately known while the existence of outer objects can only be known mediately by inference from our inner states. The Paralogisms section was entirely re-written in the B Edition, and none of the four B Paralogisms correspond precisely to the fourth A Paralogism. The A Edition “Fourth Paralogoism” is the source of many of the passages quoted above, and, historically, an important source for the phenomenalist interpretation. The fact that it was, effectively, removed in the B Edition has led many scholars to reject the phenomenalist interpretation, at least with respect to the B Edition (with some averring that he changed his mind from the A to the B  Edition).[18]  A version of the A Paralogism argument that self-consciousness requires knowledge of objects in space reappears as the “Refutation of Idealism”, added in the B Edition.
