Book 1: The End.
Chapter 11: Cannot the fortunes of survivors affect the dead?
Passing now from this question to that of the fortunes of descendants and of friends generally, the doctrine that they do not affect the departed at all seems too cold and too much opposed to popular opinion. But as the things that happen to them are many and differ in all sorts of ways, and some come home to them more and some less, so that to discuss them all separately would be a long, indeed an endless task, it will perhaps be enough to speak of them in general terms and in outline merely.
Now, as of the misfortunes that happen to a man’s self, some have a certain weight and influence on his life, while others are of less moment, so is it also with what happens to any of his friends. And, again, it always makes much more difference whether those who are affected by an occurrence are alive or dead than it does whether a terrible crime in a tragedy be enacted on the stage or merely supposed to have already taken place. We must therefore take these differences into account, and still more, perhaps, the fact that it is a doubtful question whether the dead are at all accessible to good and ill. For it appears that even if anything that happens, whether good or evil, does come home to them, yet it is something unsubstantial and slight to them if not in itself; or if not that, yet at any rate its influence is not of that magnitude or nature that it can make happy those who are not, or take away their happiness from those that are.
It seems then—to conclude—that the prosperity, and likewise the adversity, of friends does affect the dead, but not in such a way or to such an extent as to make the happy unhappy, or to do anything of the kind.
