Logik-Vorlesung: Unveroffentlichte Nachschriften (review)

Between 1755, when he received the venia legendi, and 1796, when he ended his teaching activity, Kant taught logic some 30 times. In accordance with the requirements of the Prussian ministry of culture, his course lectures were built around a recognized text, G. F. Meier's 1752 Auszug aus der Vernunftlehre. Kant did not merely present Meier's views, however, but commented on and criticized these as he thought appropriate; his own copy of Meier was full of marginal notes and interleaved with notes on separate bits of paper. When in 1799 he entrusted G. B. Jäsche with this material for the compiling of a logic text, the thought was presumably of a Kantian logic organized around Meier's framework.

Since logic plays such a prominent role in the Critical philosophy, one would expect the Jäsche logic to be viewed as an important tool for the interpretation of the Critical philosophy. But dissatisfaction with it was evident right from its original publication in 1800, and later scholars were even more negative (in 1913 Erich Adickes referred to it as "the contrivance [Machwerk]. . . that Jäsche published under the name of Kant's logic," Erich Adickes, quoted in Ak. XXIV.960). And in fact, as Pinder's careful and detailed introduction points out, the nature and origin of the Jäsche logic presented a serious problem for Wilhelm Dilthey's organization of the now-standard Akademie-Ausgabe (Kants gesammelte Schriften, herausgegeben von der königlich preussischen [now: deutschen] Akademie der Wissenschaften. Berlin: de Gruyter, 1902- Cited as "Ak.").

Dilthey conceived of four divisions of the Akademie-Ausgabe: Kant's published writings, his correspondence, his literary remains ("handschriftlicher Nachlass") and his lectures ("Vorlesungen"). Where, exactly, did the Jäsche logic belong? Kant had himself compiled a similar text from his lecture notes on anthropology, and this text was published in the first division (in volume VII). But did the Jäsche logic count as Kant's work? It was indeed authorized by Kant and based on Kant's own lecture notes; but these notes themselves were to be published in the Nachlass division. Furthermore, as it turned out, Jäsche had also employed manuscripts compiled from the lectures themselves, and these were to be published in the Vorlesungen division. This would not include his own transcription, as Erdmann had conjectured. It turns out Jäsche never heard Kant lecture on logic—he was never in Königsberg when they were being held! (xxvi, n. 29). The resulting controversies delayed the publication of the Jäsche logic in vol. IX from 1908 until 1923, after the 1914 publication in the Nachlass division of the notes on which it was based.

Dilthey's projected Vorlesungen division itself was called into question by Benno Erdmann, Dilthey's successor as Akademie-Ausgabe general editor. Erdmann recognized the questionable nature of the Jäsche logic and the other compilations, but considered Dilthey's aim for a "critically secured" edition of the lecture manuscripts as "hopeless." Still, interest in the manuscripts resulted in their piecemeal publication independently of the Akademie-Ausgabe, and when the Nachlass division's publication had been completed in 1955, the Vorlesungen division was resurrected. Vol. XXIV (in two parts) appeared in 1966; it contained the logics Blomberg, Philippi, Pölitz, Busolt, Dohna-Wundlacken and the Vienna logic, the short logic Herder, and fragments of the lost logics Hintz and Hoffmann. The Pinder volumes reviewed here contain the logics Bauch, Hechsel, and the Warsaw logic.

What exactly are the manuscripts in question? If Kant had been concerned merely to explicate Meier, his students could perhaps have been content with their marginal notes in the text and a few further ones for elucidation. But...
