 Just as Kant distinguishes a transcendental from an empirical sense of “outer” he also distinguishes a transcendental version of the appearance/thing in itself distinction (the distinction we have been concerned with up to now) from an empirical version of that distinction. The key text here is A45–46/B62–63, which for reasons of brevity will not be quoted in full (cf. the discussion of the rose at A29–30/B45, as well as A257/B313).
