Cicero: “Do not suppose, my dearest sons, that when I have left you I shall be nowhere and no one.”

Again, is there not the fact that the wisest man ever dies with the greatest cheerfulness, the most unwise with the least?

But had it not been the case that souls were immortal, it would not have been the souls of all the best men that made the greatest efforts after an immortality of fame.

For nature puts a limit to living as to everything else.

But if I am wrong in thinking the human soul immortal, I am glad to be wrong; nor will I allow the mistake which gives me so much pleasure to be wrested from me as long as I live.
