The freedom then of man, and liberty of acting according to his own will, is grounded on his having reason, which is able to instruct him in that law he is to govern himself by, and make him know how far he is left to the freedom of his own will.
The right of nature... is the liberty each man hath, to use his own power, as he will himself, for the preservation of his own nature; that is to say, of his own life.
