A quote
What you are asking about, my dear Lucilius, belongs to another topic of the same subject, and that is why I had postponed the arguments, not only on this one topic, but on other topics which also covered the same ground. For, as you know, certain logical questions are mingled with ethical ones. Accordingly, I handled the essential part of my subject which has to do with conduct—as to whether it is foolish and useless to be concerned with what lies beyond our last day, or whether our goods die with us and there is nothing left of him who is no more, or whether any profit can be attained or attempted beforehand out of that which, when it comes, we shall not be capable of feeling.
