Titus Lucretius Carus said this quote

A man leaves his great house because he's boredWith life at home, and suddenly returns,Finding himself no happier abroad.He rushes off to his villa driving like mad,You'ld think he's going to a house on fire,And yawns before he's put his foot inside,Or falls asleep and seeks oblivion,Or even rushes back to town again.So each man flies from himself (vain hope, becauseIt clings to him the more closely against his will)And hates himself because he is sick in mindAnd does not know the cause of his disease.

~ Titus Lucretius Carus

The supply of matter in the universe was never more tightly packed than it is now, or more widely spread out. For nothing is ever added to it or subtracted from it. It follows that the movement of atoms today is no different from what it was in bygone ages and always will be. So the things that have regularly come into being will continue to come into being in the same manner; they will be and grow and flourish so far as each is allowed by the laws of nature.

~ Titus Lucretius Carus

Visible objects therefore do not perish utterly, since nature repairs one thing from another and allows nothing to be born without the aid of another's death.

~ Titus Lucretius Carus

Furthermore, as the body suffers the horrors of disease and the pangs of pain, so we see the mind stabbed with anguish, grief and fear. What more natural than that it should likewise have a share in death?
