--[Sensitive Morality, or the Materialism of the Sage.]--Interruptions, the cause of which will soon appear, prevented me from continuing it, and the fate of the sketch, which is more connected with my own than it may appear to be, will hereafter be seen. Besides this, I had for some time meditated a system of education, of which Madam de Chenonceaux, alarmed for her son by that of her husband, had desired me to consider. The authority of friendship placed this object, although less in itself to my taste, nearer to my heart than any other. On which account this subject, of all those of which I have just spoken, is the only one I carried to its utmost extent. The end I proposed to myself in treating of it should, I think, have procured the author a better fate. But I will not here anticipate this melancholy subject. I shall have too much reason to speak of it in the course of my work. These different objects offered me subjects of meditation for my walks; for, as I believed I had already observed, I am unable to reflect when I am not walking: the moment I stop, I think no more, and as soon as I am again in motion my head resumes its workings. I had, however, provided myself with a work for the closet upon rainy days. This was my dictionary of music, which my scattered, mutilated, and unshapen materials made it necessary to rewrite almost entirely. I had with me some books necessary to this purpose; I had spent two months in making extracts from others, I had borrowed from the king's library, whence I was permitted to take several to the Hermitage. I was thus provided with materials for composing in my apartment when the weather did not permit me to go out, and my copying fatigued me. This arrangement was so convenient that it made it turn to advantage as well at the Hermitage as at Montmorency, and afterwards even at Motiers, where I completed the work whilst I was engaged in others, and constantly found a change of occupation to be a real relaxation.
