Rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add "within the limits of the law" because law is often but the tyrant's will, and always so when it violates the rights of the individual.
When human statecraft attaches a chain to the feet of a free man, whom it makes a slave in contempt of nature and citizenship, eternal justice rivets the other end about the tyrant's neck.louis antoine de saint-just
The man resolved, and steady to his trust, Inflexible to ill, and obstinately just, May the rude rabble's insolence despise, Their senseless clamours and tumultuous cries; The tyrant's fierceness he beguiles, And the stern brow, and the harsh voice defies, And with superior greatness smiles.joseph addison
Zeno, the disciple of Parmenides , having attempted to kill the tyrant Demylus, and failing in his design, maintained the doctrine of Parmenides, like pure and fine gold tried in the fire, that there is nothing which a magnanimous man ought to dread but dishonor, and that there are none but children and women, or effeminate and women-hearted men, who fear pain. For, having with his own teeth bitten off his tongue, he spit it in the tyrant's face.
