Abstract

In lieu of an abstract, here is a brief excerpt of the content:Hume and Tetens Manfred Kuehn Kant was neither the only nor even the first German philosopher who publicly responded to Hume. Indeed, there were many. But there were none who came as close to appreciatingHume as didJohann Nicolaus Tetens, who, in his two main works, the Über die allgemeine speculativische Philosophie or On General Speculative Philosophy (1775), and the Philosophische Versuche über die menschliche Natur und ihre Entwicklung or Philosophical Essays on Human Nature and itsDevelopment (1?7), not only argued that Hume was a philosophical force to be reckoned with, but also seemed to think that philosophical progress wasimpossiblewithoutan extensionandfurtherdevelopment ofHumean views. This alone would make him an interesting figure in the history of the reception of Hume's philosophy, but, since Tetens is one ofthe most important representatives ofempiricism in eighteenthcentury Germany, and since he put forward ideas that demonstrably influenced Kant, he is perhaps still more interesting. In any case, it is most regrettable that he still is so little studied in Germany today, and that he is almost completely unknown in English-speaking countries. Though Lewis White Beck has offered an interesting discussion of Tetens' critique ofHume in his book on Early German Philosophy, and though some Anglo-American Kant scholars are somewhat aware of Tetens' influence upon Kant, his name is almost never mentioned by philosophical scholars concerned with Hume. If this paper were to remind them of Tetens and his possible importance for the discussion ofissues raised by Hume, I would be very happy. Nevertheless, I must admit to an ulterior motive, for I am not interested in the relationship ofTetens and Hume per se, but rather in how Tetens' discussion ofHume might have influenced Kant's conception of "Hume's problem." My question is: "What could Kant have learned from Tetens about Hume in 1777, that is, about four years before the publication of his Critique ofPure Reason?" To this end, I shall first briefly review the evidence for Kant's study of Tetens; secondly say something about Tetens' discussion of the self; thirdly sketch his theory ofthe causal principle as a special case ofhis laws of association; fourthly represent an important part of his theory of objectiveornecessarytruth; andfinallytryto showhowall ofthismight be significant for our understanding of the development of Kant's position vis a vis Hume. Volume XV Number 2 365 MANFRED KUEHN IL Johann Georg Hamann, always interestedinliterarygossip and always ready to spread it, wrote to Johann Gottfried Herder on May 12, 1779 that Kant was writing on his Critique, and that he had "always open on his desk" Tetens' work. Two years earlier, on October 12, 1777, he had already told him that Kant was "said to be very full of... Tetens." Hamann, mischievous as he could be, not only wanted to bring Kant's former student up to date on the work of his teacher, but clearly also made a comment on Kant's originality. But there are other indications that Kant carefully studied Tetens between 1777 and 1781. Thus, Kant's correspondence with Herz in 1778 contains references to Tetens as having said things of importance, and his reflections of the period also mention him. One ofthe most telling indications ofhis rather close reading ofTetens is to be found in one ofhis letters to the publisher of his first Critique: On October 15, 1780 he writes to him that he would prefer not to have the book set in the type of Tetens' Essays because the latter is "really tiring" to his eyes. That Tetens' work did not only tire his eyes, but also stimulated his thoughts can be seen from one of his preparatory manuscripts to his Prolegomena of 1783, for there Kant suggested that Tetens could have given people occasion to think about the very problem of the Critique. Though he considered Tetens' attempt concerning the possibility of a priori knowledge as failed, he also viewed it as one of the most important attempts in that direction.??. It is well known that Kant himselfclaimed that "Hume's problem" was what first woke him from his dogmatic slumber. Though there is no similar pronouncement by Tetens, it is clear that he not only knew Hume well, but...
