"Why need we weep over parts of our life? the whole of it calls for tears: new miseries assail us before we have freed ourselves from the old ones. You, therefore, who allow them to trouble you to an unreasonable extent ought especially to restrain yourselves, and to muster all the powers of the human breast to combat your fears and your pains. Moreover, what forgetfulness of your own position and that of mankind is this? You were born a mortal, and you have given birth to mortals: yourself a weak and fragile body, liable to all diseases, can you have hoped to produce anything strong and lasting from such unstable materials? Your son has died: in other words he has reached that goal towards which those whom you regard as more fortunate than your offspring are still hastening: this is the point towards which move at different rates all the crowds which are squabbling in the law courts, sitting in the theatres, praying in the temples. Those whom you love and those whom you despise will both be made equal in the same ashes."
