To further, so far as in us lies, the growth of the sciences is to work in your Excellency’s own interest, your own interest being intimately connected with them, not only through the exalted position of a patron of science, but through the far more intimate relation of a lover and enlightened judge. For that reason I avail myself of the only means within my power of proving my gratitude for the gracious confidence with which your Excellency honours me, as if I too could help toward your noble work.
[Whoever delights in a speculative life finds with moderate wishes the approval of an enlightened and kind judge a powerful incentive to studies the results of which are great, but remote, and therefore entirely ignored by vulgar eyes.]
To you, as such a judge, and to your kind attention I now submit this book, placing all other concerns of my literary future under your special protection, and remaining with profound respect
Your Excellency’s Most obedient Servant,
IMMANUEL KANT.
Königsberg,March 29, 1781.
