Book VIII · 58

He who fears death either fears the loss of sensation or a different kind of sensation. But if thou shalt have no sensation, neither wilt thou feel any harm; and if thou shalt acquire another kind of sensation, thou wilt be a different kind of living being and thou wilt not cease to live.

Dread of death is a dread of non-sensation or new sensation. But either thou wilt feel no sensation, and so no sensation of any evil; or a different kind of sensation will be thine, and so the life of a different creature, but still a life.
