who finding the trouble of thinking very fatiguing, preferred, in things which pleased him, throwing a light upon and extending the ideas of others, to producing any himself.  Besides, not being confined to the functions of a translator, I was at liberty sometimes to think for myself; and I had it in my power to give such a form to my work, that many important truths would pass in it under the name of the Abbe de Saint Pierre, much more safely than under mine.  The undertaking also was not trifling; the business was nothing less than to read and meditate twenty-three volumes, diffuse, confused, full of long narrations and periods, repetitions, and false or little views, from amongst which it was necessary to select some few that were good and useful, and sufficiently encouraging to enable me to support the painful labor.  I frequently wished to have given it up, and should have done so, could I have got it off my hands with a great grace; but when I received the manuscripts of the abbe, which were given to me by his nephew, the Comte de Saint Pierre, I had, by the solicitation of St. Lambert, in some measure engaged to make use of them, which I must either have done, or have given them back.  It was with the former intention I had taken the manuscripts to the Hermitage, and this was the first work to which I proposed to dedicate my leisure hours.

I had likewise in my own mind projected a third, the idea of which I owed to the observations I had made upon myself and I felt the more disposed to undertake this work, as I had reason to hope I could make it a truly useful one, and perhaps, the most so of any that could be offered to the world, were the execution equal to the plan I had laid down.  It has been remarked that most men are in the course of their lives frequently unlike themselves, and seem to be transformed into others very different from what they were.  It was not to establish a thing so generally known that I wished to write a book; I had a newer and more important object.  This was to search for the causes of these variations, and, by confining my observations to those which depend on ourselves, to demonstrate in what manner it might be possible to direct them, in order to render us better and more certain of our dispositions.  For it is undoubtedly more painful to an honest man to resist desires already formed, and which it is his duty to subdue, than to prevent, change, or modify the same desires in their source, were he capable of tracing them to it.  A man under temptation resists once because he has strength of mind, he yields another time because this is overcome; had it been the same as before he would again have triumphed.
