Lucretius

We are each of us angels with only one wing, and we can only fly by embracing one another.

All things keep on in everlasting motion, out of the infinite come the particles speeding above, below, in endless dance.

Therefore, this terror of the mind and the darkness must be dispelled not by the rays of the sun or the bright light of day, but by the appearance and reasoning of nature.

So it is more useful to watch a man in times of peril, and in adversity to discern what kind of man he is; for then at last words of truth are drawn from the depths of his heart, and the mask is torn off, reality remains.

Vitaque mancipio nulli datur, omnibus usu.

It is pleasant, with the sea raging under the winds, to gaze upon the great struggles of another from the land.

From nothing comes nothing. Nothing that exists can be destroyed. All changes are due to the combination and separation of atoms.

Cedit item retro, de terra quod fuit ante, in terras.

Some races wax and others wane, and in a short space the generations of living creatures are changed, and like runners they pass on the torch of life.
