text: If I may begin with a commonplace remark, spring is gradually disclosing itself; but though it is rounding into summer, when you would expect hot weather, it has kept rather cool, and one cannot yet be sure of it. For it often slides back into winter weather. Do you wish to know how uncertain it still is? I do not yet trust myself to a bath which is absolutely cold; even at this time I break its chill. You may say that this is no way to show the endurance either of heat or of cold; very true, dear Lucilius, but at my time of life one is at length contented with the natural chill of the body. I can scarcely thaw out in the middle of summer. Accordingly, I spend most of the time bundled up; and I thank old age for keeping me fastened to my bed. Why should I not thank old age on this account? That which I ought not to wish to do, I lack the ability to do. Most of my converse is with books. Whenever your letters arrive, I imagine that I am with you, and I have the feeling that I am about to speak my answer, instead of writing it. Therefore let us together investigate the nature of this problem of yours, just as if we were conversing with one another.
