All mankind... being all equal and independent, no one ought to harm another in his life, health, liberty or possessions.
John LockeHe would be laughed at, that should go about to make a fine dancer out of a country hedger, at past fifty. And he will not have much better success, who shall endeavour, at that age, to make a man reason well, or speak handsomely, who has never been used to it, though you should lay before him a collection of all the best precepts of logic or oratory.
John LockeThirdly, the supreme power cannot take from any man any part of his property without his own consent: for the preservation of property being the end of government, and that for which men enter into society, it necessarily supposes and requires, that the people should have property, without which they must be supposed to lose that, by entering into society, which was the end for which they entered into it; too gross an absurdity for any man to own.
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.
