Johann Gottfried Karl Christian Kiesewetter (1766-1819)

[This is a version of an article in The Dictionary of Eighteenth Century German Philosophers, 3 vols., edited by Manfred Kuehn and Heiner Klemme (London/New York: Continuum, 2010).]

Johann Gottfried Karl Christian Kiesewetter, the son of a school teacher, was born on 4 November 1766 in Berlin, where he also died at the age of 52 on 9 July 1819, after an illness of several years.  His importance lies primarily in his association with Immanuel Kant and in his many publications popularizing Kant’s philosophy; for Kant, he also served as a well-positioned source of Berlin court gossip.

Kiesewetter studied at the Grauen Kloster Gymnasium in Berlin where his academic abilities attracted the attention of the court, resulting in Frederick II granting a stipend for him to attend the university at Halle, where he enrolled in 1780 and studied theology (under J. S. Semler [bio], J. A. Nösselt [bio], Niemeyer, and Knapp), mathematics (W. J. G. Karsten [bio] and G. S. Klügel [bio]), philology (F. A. Wolf) and philosophy (under L. H. Jakob [bio] and J. A. Eberhard [bio]).  His academic gifts soon won him a post teaching mathematics at the local Orphanage School.  It was in Jakob’s lectures that Kiesewetter became acquainted with Kant’s philosophy, and he eventually requested permission and assistance from the newly crowned king, Friedrich Wilhelm II, for relocating to Königsberg.  He was given 300 thaler and free travel to Königsberg, where he matriculated on 10 Nov 1788 (Kant received a 60% raise in salary at this time, by special order of the king, and Flittner claims this was tied to Kiesewetter’s visit).  Kiesewetter attended Kant’s lectures, as well as his weekly orals, and was eventually included among Kant’s regular table guests, where he made the acquaintance of C. J. Kraus [bio] and others in Kant’s circle.  He also began serving as Kant’s copyist (it is in his hand that we find the manuscript of the first introduction to Kant’s Critique of Judgment).  During this time he wrote to an acquaintance that he “has found a second father in Professor Kant” (qtd. in Malter 1990, 342).  Together with Kant’s later biographer, R. B. Jachmann [bio], Kiesewetter presented a poem to Kant on the occasion of his birthday that spring (22 April 1789; reprinted at Ak. 12:407).

Kiesewetter stayed in Königsberg for just two semesters, leaving for Berlin on or shortly after 15 October 1789, where he assumed a post as tutor to the three younger children of the King (Auguste, and the two boys Heinrich and Wilhelm).  What would become an extensive correspondence with Kant began on 19 November 1789 (#391; Ak. 11:107), after his return to Berlin, and in this letter we learn that he would be correcting proofs for the Critique of Judgment, which was being printed in Berlin by the publisher Lagarde (Kant had already asked Lagarde to hire Kiesewetter for this purpose).  Kiesewetter received his magister degree the next summer from Halle (2 June 1790), after which he made a second visit to Königsberg (during September and October); several important “Reflections” in Kant’s Nachlass are linked to this visit (cf. ##5661-5663, 6311-6317; Ak. 18:318-23, 607-29).

Once back in Berlin, Kiesewetter offered private lectures on Kant’s philosophy, as well as an annual public set of logic lectures that Wöllner (the minister of education) required of him, although he received no salary for this other than his payment for working as a tutor in the royal household.  Finally, in 1793, he was appointed professor of mathematics and philosophy at the Pepinière (the Collegium medico-chirurgicum in Berlin), and in 1798 professor of logic at the Military Academy, all the while lecturing primarily on mathematics and logic.

In 1804 Kiesewetter conducted an official tour through Germany, Switzerland, France and Italy inspecting the educational programs of their military schools, and was on hand to witness the eruption of Vesuvius in August.  He visited Königsberg yet a third time in 1807, keeping ahead of Napolean’s troops, and would have emigrated to Russia but for the Treaty of Tilsit.  He volunteered with the Prussian army during the wars of liberation in 1813, but became ill near Weimar and returned to Berlin, remaining incapacitated by this illness until his death in 1819.

Kiesewetter is occasionally mentioned as having taught logic and mathematics to the military strategist Carl von Clausewitz when the latter began his studies at the Military Academy in 1801.  Kiesewetter exposed him to Kant’s philosophy in particular, and there has been considerable discussion as to the extent and effect of this Kantian influence.

Publication of Kiesewetter’s logic textbook (1791), complete with an effusive dedication to Kant, nearly led to a break with his mentor, who believed Kiesewetter had plagiarized from his lectures, and in any event had kept the publication secret from him.  Both Kiesewetter and the publisher Lagarde proclaimed their innocence in letters to Kant (July 3 and 5, 1791; Ak. 11:265-9).

Kiesewetter was clearly a gifted teacher and a prolific author, writing numerous Kant-inspired textbooks, although much of this was rehashed earlier work; and while his popularizations, especially his Versuch (1795), sold quite well, they often sacrificed accuracy in pursuit of clarity, and in the end did little to advance the Kantian cause, insofar as they merely won over “a mass of incompetent adherents” (Adickes).
