“Whatsoever therefore is consequent to a time of war, where every man is enemy to every man, the same consequent to the time wherein men live without other security than what their own strength and their own invention shall furnish them withal. In such condition there is no place for industry… no knowledge of the face of the earth; no account of time; no arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.”

The Kasîdah of Hâjî Abdû El-Yezdî (1870)
Context: Haply the Law that rules the world allows to man the widest range;
And haply Fate's a Theist-word, subject to human chance and change.
This "I" may find a future Life, a nobler copy of our own,
Where every riddle shall be ree'd, where every knowledge shall be known;
Where 'twill be man's to see the whole of what on Earth he sees in part;
Where change shall ne'er surcharge the thought; nor hope defer'd shall hurt the heart.

Horatius, st. 26 & 27; this quote is often truncated to read:
Lays of Ancient Rome (1842)
Context: Then out spake brave Horatius,
The Captain of the Gate:
"To every man upon this earth
Death cometh soon or late.
And how can man die better
Than facing fearful odds,
For the ashes of his fathers,
And the temples of his gods, And for the tender mother
Who dandled him to rest,
And for the wife who nurses
His baby at her breast,
And for the holy maidens
Who feed the eternal flame,
To save them from false Sextus
That wrought the deed of shame?"
