Therefore those who, as Sallust puts it, “hearken to their bellies,” should be numbered among the animals, and not among men; and certain men, indeed, should be numbered, not even among the animals, but among the dead. He really lives who is made use of by many; he really lives who makes use of himself. Those men, however, who creep into a hole and grow torpid are no better off in their homes than if they were in their tombs. Right there on the marble lintel of the house of such a man you may inscribe his name, for he has died before he is dead. Farewell. Let us cease to desire that which we have been desiring. I, at least, am doing this: in my old age I have ceased to desire what I desired when a boy. To this single end my days and my nights are passed; this is my task, this the object of my thoughts,—to put an end to my chronic ills.
The quote: I am endeavouring to live every day as if it were a complete life. I do not indeed snatch it up as if it were my last; I do regard it, however, as if it might even be my last.
The present letter is written to you with this in mind,—as if death were about to call me away in the very act of writing. I am ready to depart, and I shall enjoy life just because I am not over-anxious as to the future date of my departure. Before I became old I tried to live well; now that I am old, I shall try to die well; but dying well means dying gladly. See to it that you never do anything unwillingly. That which is bound to be a necessity if you rebel, is not a necessity if you desire it.
