"But if any one should ask: must the people, then, always lay themselves open to the cruelty and rage of tyranny - must they see their cities pillaged and laid in ashes, their wives and children exposed to the tyrants lust and fury, and themselves and their families reduced by their king to ruin and all the miseries of want and oppression, and yet sit still? Must men alone be debarred the common privilege of opposing force with force, which Nature allows so freely to all other creatures for their preservation from injury? I answer: Self-defense is a part of the law of nature; nor can it be denied the community, even against the King himself." - Barclay, Against Monarchy.
