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.
Thomas HobbesBy consequence, or train of thoughts, I understand that succession of one thought to another which is called, to distinguish it from discourse in words, mental discourse. When a man thinketh on anything whatsoever, his next thought after is not altogether so casual as it seems to be. Not every thought to every thought succeeds indifferently.
Thomas HobbesWhat reason is there that he which laboreth much, and, sparing the fruits of his labor, consumeth little, should be more charged than he that, living idly, getteth little and spendeth all he gets, seeing the one hath no more protection from the commonwealth than the other?
