If souls continue to exist, how does the air contain them from eternity?- But how does the earth contain the bodies of those who have been buried from time so remote? For as here the mutation of these bodies after a certain continuance, whatever it may be, and their dissolution make room for other dead bodies; so the souls which are removed into the air after subsisting for some time are transmuted and diffused, and assume a fiery nature by being received into the seminal intelligence of the universe, and in this way make room for the fresh souls which come to dwell there. And this is the answer which a man might give on the hypothesis of souls continuing to exist. But we must not only think of the number of bodies which are thus buried, but also of the number of animals which are daily eaten by us and the other animals. For what a number is consumed, and thus in a manner buried in the bodies of those who feed on them! And nevertheless this earth receives them by reason of the changes of these bodies into blood, and the transformations into the aerial or the fiery element.
Things are in such a kind of envelopment that they have seemed to philosophers, not a few nor those common philosophers, altogether unintelligible; nay even to the Stoics themselves they seem difficult to understand. And all our assent is changeable; for where is the man who never changes? Carry thy thoughts then to the objects themselves, and consider how short-lived they are and worthless, and that they may be in the possession of a filthy wretch or a whore or a robber. Then turn to the morals of those who live with thee, and it is hardly possible to endure even the most agreeable of them, to say nothing of a man being hardly able to endure himself. In such darkness then and dirt and in so constant a flux both of substance and of time, and of motion and of things moved, what there is worth being highly prized or even an object of serious pursuit, I cannot imagine. But on the contrary it is a man's duty to comfort himself, and to wait for the natural dissolution and not to be vexed at the delay, but to rest in these principles only: the one, that nothing will happen to me which is not conformable to the nature of the universe; and the other, that it is in my power never to act contrary to my god and daemon: for there is no man who will compel me to this.
That which has grown from the earth to the earth, But that which has sprung from heavenly seed, Back to the heavenly realms returns. This is either a dissolution of the mutual involution of the atoms, or a similar dispersion of the unsentient elements.
Lucilla saw Verus die, and then Lucilla died. Secunda saw Maximus die, and then Secunda died. Epitynchanus saw Diotimus die, and Epitynchanus died. Antoninus saw Faustina die, and then Antoninus died. Such is everything. Celer saw Hadrian die, and then Celer died. And those sharp-witted men, either seers or men inflated with pride, where are they? For instance the sharp-witted men, Charax and Demetrius the Platonist and Eudaemon, and any one else like them. All ephemeral, dead long ago. Some indeed have not been remembered even for a short time, and others have become the heroes of fables, and again others have disappeared even from fables. Remember this then, that this little compound, thyself, must either be dissolved, or thy poor breath must be extinguished, or be removed and placed elsewhere.
Do not despise death, but be well content with it, since this too is one of those things which nature wills. For such as it is to be young and to grow old, and to increase and to reach maturity, and to have teeth and beard and grey hairs, and to beget, and to be pregnant and to bring forth, and all the other natural operations which the seasons of thy life bring, such also is dissolution. This, then, is consistent with the character of a reflecting man, to be neither careless nor impatient nor contemptuous with respect to death, but to wait for it as one of the operations of nature.
Thou canst remove out of the way many useless things among those which disturb thee, for they lie entirely in thy opinion; and thou wilt then gain for thyself ample space by comprehending the whole universe in thy mind, and by contemplating the eternity of time, and observing the rapid change of every several thing, how short is the time from birth to dissolution, and the illimitable time before birth as well as the equally boundless time after dissolution.
All that thou seest will quickly perish, and those who have been spectators of its dissolution will very soon perish too. And he who dies at the extremest old age will be brought into the same condition with him who died prematurely.
Look at everything that exists, and observe that it is already in dissolution and in change, and as it were putrefaction or dispersion, or that everything is so constituted by nature as to die.
