John LockeWhensoever, therefore, the legislative shall transgress this fundamental rule of society, and either by ambition, fear, folly, or corruption, endeavour to grasp themselves, or put into the hands of any other, an absolute power over the lives, liberties, and estates of the people, by this breach of trust they forfeit the power the people had put into the hands... and it devolves to the people, who have a right to resume their original liberty, and... provide for their own safety and security.
John LockeAnger is uneasiness or discomposure of the mind upon the receipt of any injury, with a present purpose of revenge
