It is a year and a half now since Kant commissioned me to prepare his Logic for publication, as he expounded it to his listeners in public lectures, and to transmit it to the public in the form of a compendious manual. For this purpose I received from him his own manuscript, which he had used in his lectures, with the expression of special, honorable confidence in me, that, being acquainted with the principles of his system in general, I would easily enter into the course of his ideas, that I would not distort or falsify his thoughts, but rather would present them with the required clarity and distinctness and at the same time in the appropriate order. Now since, as I thus accepted the commission and have sought to carry it out as well as I was able, in conformity with the wish and the expectation of that praiseworthy wise man, my most honored teacher and friend, everything that concerns the exposition, the clothing and the execution, the presentation and the ordering of the thoughts, is in part to be reckoned to my account, I am naturally obliged to provide an account to the readers of this new Kantian work. On this matter, then, a few closer explanations here.
