Hufeland, Christoph Wilhelm (Kant in the Classroom)
The Naragon biographical record of Hufeland, part of Steve Naragon’s Kant in the Classroom project at Manchester University, is the secondary source used in this case for the Kant-Hufeland correspondence. It states verbatim that ‘Hufeland sent a copy of this work to Immanuel Kant, who responded quite favorably in an open letter that Hufeland published in his Journal and that forms the third part of Kant’s Conflict of the Faculties (1798).’ The record independently corroborates two other facts used in this case: the first edition as Die Kunst das menschliche Leben zu verlängern (Jena, 1797), and Hufeland’s standing as physician to the Weimar circle (Wieland, Herder, Goethe, and Schiller). It is cited with its stated copyright year of 2006 (last modified 2010). The primary work itself is the separate Kant source entry (the 1798 Conflict of the Faculties).
