I do not feel pleasure in writing of the subjects which I was wont to discuss; I am not at liberty to write of new themes. I see that the one would not suit you, and that for the other I have no leisure. For, since I left you, neither opportunity nor leisure has been given me for taking up and revolving the things which we are accustomed to investigate together. The winter nights are indeed too long, and they are not entirely spent in sleep by me; but when I have leisure, other subjects [than those which we used to discuss] present themselves as having a prior claim on my consideration. ¹ What, then, am I to do? Am I to be to you as one dumb, who cannot speak, or as one silent, who will not speak? Neither of these things is desired, either by you or by me. Come, then, and bear what the end of the night succeeded in eliciting from me during the time in which it was devoted to following out the subject of this letter.
