WWV I, Anhang: Kant's greatest merit is the distinction of appearance from the thing in itself
The opening of the appendix: its first sentence names the distinction of appearance from the thing in itself as Kant's greatest merit and gives its ground, the sentences on Locke set the Lockean distinction of primary and secondary qualities beside it, and the sixth sentence says what the Kantian distinction declares of Locke's primary qualities and why. The paragraph continues, on the separation of cognition a priori from a posteriori, on Kant's threefold relation to Locke, Hume and Leibniz-Wolff, and on Plato and the Vedas; those sentences are not stored, and the paragraph's later sentences from »Er zeigte« are in p-wwv1-anhang-laws-of-experience-not-applicable-to-existence-itself. The transcription has »ungleich hohem Standpunkt«, where Grisebach's edition (Projekt Gutenberg-DE) reads »ungleich höhern Standpunkt«; the original keeps the transcription's letters and the translation renders the sense, »higher«. »Prolegomena zu jeder Metaphysik, § 13, Anm. 2« is Schopenhauer's reference to Kant's second note to § 13 of the Prolegomena. »Nachweisung« is rendered »showing«, as »nachweisen« is on the other Schopenhauer passages. A word-by-word comparison with Grisebach's text found, besides that slip, orthography (»d.h.«) and four variants: »Auf diesen Weg« where Grisebach prints »Aus diesen Weg«, his error; »Beweglichkeit, beilegte« where he has no comma; »Vorspiel des Kantischen« where he reads »der Kantischen«; and, in the last sentence, »weil Bedingungen desselben« where he reads »weil die Bedingungen desselben«. The original keeps the transcription's text in each place; the translation's »a prelude to the Kantian one« and »its conditions« follow the sense, which both readings bear.
