Add to this the diseases which we bring upon us with our own hands, and the time which has laid idle without any use having been made of it; you will see that you have not lived as many years as you count. Look back in your memory and see how often you have been consistent in your projects, how many days passed as you intended them to do when you were at your own disposal, how often you did not change colour and your spirit did not quail, how much work you have done in so long a time, how many people have without your knowledge stolen parts of your life from you, how much you have lost, how large a part has been taken up by useless grief, foolish gladness, greedy desire, or polite conversation; how little of yourself is left to you: you will then perceive that you will die prematurely.” What, then, is the reason of this? It is that people live as though they would live forever: you never remember your human frailty; you never notice how much of your time has already gone by: you spend it as though you had an abundant and overflowing store of it, though all the while that day which you devote to some man or to some thing is perhaps your last. You fear everything, like mortals as you are, and yet you desire everything as if you were immortals.
