Find out just what the people will submit to and you have found out the exact amount of injustice and wrong which will be imposed upon them; and these will continue until they are resisted with either words or blows, or with both. The limits of tyrants are prescribed by the endurance of those whom they oppress.
Aug. 4, 1857
Any power that can be abused will be abused.
Abuse always expands to fill the limits of resistance to it.
If people don't resist the abuses of others, they will have no one to resist the abuses of themselves, and tyranny will prevail.
