We must do our duty and convince the world that we are just friends and brave enemies
Nature [has] implanted in our breasts a love of others, a sense of duty to them, a moral instinct, in short, which prompts us irresistibly to feel and to succor their distresses.
If you have any duty which must be done, and it seems disagreeable, do it promptly and have it over.
The interests of a nation, when well understood, will be found to coincide with their moral duties.
When tyranny becomes law, rebellion becomes duty.
