All the rest of my misfortunes during my life were the inevitable effect of this moment of error.

My sentiments became elevated with the most inconceivable rapidity to the level of my ideas.  All my little passions were stifled by the enthusiasm of truth, liberty, and virtue; and, what is most astonishing, this effervescence continued in my mind upwards of five years, to as great a degree perhaps as it has ever done in that of any other man.  I composed the discourse in a very singular manner, and in that style which I have always followed in my other works.  I dedicated to it the hours of the night in which sleep deserted me, I meditated in my bed with my eyes closed, and in my mind turned over and over again my periods with incredible labor and care; the moment they were finished to my satisfaction, I deposited them in my memory, until I had an opportunity of committing them to paper; but the time of rising and putting on my clothes made me lose everything, and when I took up my pen I recollected but little of what I had composed.  I made Madam le Vasseur my secretary; I had lodged her with her daughter, and husband, nearer to myself; and she, to save me the expense of a servant, came every morning to make my fire, and to do such other little things as were necessary.  As soon as she arrived I dictated to her while in bed what I had composed in the night, and this method, which for a long time I observed, preserved me many things I should otherwise have forgotten.

As soon as the discourse was finished, I showed it to Diderot.  He was satisfied with the production, and pointed out some corrections he thought necessary to be made.

However, this composition, full of force and fire, absolutely wants logic and order; of all the works I ever wrote, this is the weakest in reasoning, and the most devoid of number and harmony.  With whatever talent a man may be born, the art of writing is not easily learned.

I sent off this piece without mentioning it to anybody, except, I think, to Grimm, with whom, after his going to live with the Comte de Vriese, I began to be upon the most intimate footing.  His harpsichord served as a rendezvous, and I passed with him at it all the moments I had to spare, in singing Italian airs, and barcaroles; sometimes without intermission, from morning till night, or rather from night until morning; and when I was not to be found at Madam Dupin’s, everybody concluded I was with Grimm at his apartment, the public walk, or theatre.  I left off going to the Comedie Italienne, of which I was free, to go with him, and pay, to the Comedie Francoise, of which he was passionately fond.  In short, so powerful an attraction connected me with this young man, and I became so inseparable from him, that the poor aunt herself was rather neglected, that is, I saw her less frequently; for in no moment of my life has my attachment to her been diminished.
