In the current Easter book fair there will appear a book of mine, entitled Critique of Pure Reason. It is being published by Hartknoch's firm, printed in Halle by Grunert, and distributed under the direction of Herr Spener, the Berlin book dealer. This book contains the result of all the varied investigations, which start from the concepts we debated together under the heading “the sensible world and the intelligible world” [mundi sensibilis und intelligibilis], I am anxious to hand over the summation of my efforts to the same insightful man who deigned to cultivate my ideas, so discerning a man that he penetrated those ideas more deeply than anyone else.

With this in mind I beg you to deliver the enclosed letter in person to Herr Carl Spener and to arrange the following matters with him; after you talk with him, please send me news with the earliest possible mail, if my demands are not too extravagant.

Find out how far along the printing is and on which day of the fair the book will appear in Leipzig.

Since I intended that four copies go to Berlin – a dedicatory copy to His Excellency, Minister von Zedlitz, one for you, one for Herr Mendelssohn, and one for Dr. Sell, which last should please be delivered to the music master, Herr Reichard (who recently sent me a copy of Sell's Philosophische Gespräche), I beg that you ask Herr Spener to write to Halle immediately and see to it that these four copies be sent to Berlin, at my expense, as soon as the printing is done and that they be delivered to you.
