Following the publication of The Critique of Pure Reason, Immanuel Kant's controversial thesis of transcendental idealism was charged with being a revision of Berkeleyan idealism, a doctrine which proclaims that there are no external material bodies, and all that exists in the world are minds and ideas. Before the first and the second editions of the Critique, Prolegomena to Any Future Metaphysics was released, in which Kant both clarifies points made in the Critique and responds this accusation (Heide 26 Nov). This paper will first explicate his account of transcendental idealism as found in the Critique and compare it to the reply to his critics from Prolegomena. Despite there seeming to be inconsistency between the position espoused in the

While it has transcendental ideality in the sense that it is not a property belonging to external objects in themselves, instead existing as an a priori intuition within us, space continues to have empirical reality in that it applies to all the appearances we have of external objects. (A28/B44). Kant ultimately holds that space is not intuited as existing in anything itself, as a form which we impose onto objects around us, and that these which are intuited as existing in space are nothing other than appearances of the faculty of sensibility. The intuition of space does, nevertheless, have as its “true correlate... the thing in itself,” it is simply that things in themselves cannot be “known to us” (A30). In the end, “we are acquainted with nothing except our way of perceiving [external objects],” which always occurs through the lens of our pure representation of space …show more content…
This is largely, he explains, because intuitions are representations which do rely on there being an object to represent (sec. 8, 4:282). Yet, were intuitions representative of properties actually in objects themselves, they could only ever be empirical. Pure intuitions, those involving only form and nothing from matter or sensation, are the only sort which can “precede the actuality of the object and... all actual impressions through which I am affected by objects” (sec. 9, 4:282). This has the outcome that an a priori (pure) intuition (of space) can represent “objects only as they appear to us (to our senses), not as they may be in themselves” (4:283). These passages relate to a point of clarification found in the footnotes of the Critique, in which Kant asserts that intuitions pertain to objects, while sensations pertain “merely to the subject” (p. 155). Initially, it might seem odd for Kant to refer to a pure intuition as representative of an “object of sense.” However, although objects affect us through sensation, such objects, which are “of our senses,” are can nevertheless only be intuited a priori if their qualities are intuited through a pure form, which we subjectively impose. In the Prolegomena, Kant uses geometry to illustrate that one can, from empirical intuitions of geometrical bodies, remove all of the empirical (sensory) content and still be left with the
