“If men and mortal arms ye slight,
Know there are gods who watch o'er right.”

Ode in Imitation of Alcæus, reported in Bartlett's Familiar Quotations, 10th ed. (1919). Compare: "Neither walls, theatres, porches, nor senseless equipage, make states, but men who are able to rely upon themselves", Aristides, Orations (Jebb's edition), vol. i. (trans. by A. W. Austin); By Themistocles alone, or with very few others, does this saying appear to be approved, which, though Alcæus formerly had produced, many afterwards claimed: "Not stones, nor wood, nor the art of artisans, make a state; but where men are who know how to take care of themselves, these are cities and walls."—Ibid. vol. ii.

The Caesars (c. 361)
Context: Know all ye mortals who have entered this contest,
that according to our laws and decrees the victor is
allowed to exult but the vanquished must not complain.
Depart then wherever you please, and in future live
every one of you under the guidance of the gods.
Let every man choose his own guardian and guide.

Context: Libraries … will be the best security for maintaining our liberties. A nation of well-informed men, who have been taught to know and prize the rights which God has given them, cannot be enslaved. It is in the regions of ignorance that tyranny reigns.
