From whence it happens, that they which trust to books, do as they that cast up many little sums into a greater, without considering whether those little sums were rightly cast up or not; and at last finding the error visible, and not mistrusting their first grounds, know not which way to clear themselves; but spend time in fluttering over their books, as birds that entering by the chimney, and finding themselves enclosed in a chamber, flutter at the false light of a glass window, for want of wit to consider which way they came in.
Thomas HobbesFor seeing life is but a motion of Limbs... why may we not say, that all Automata (Engines that move themselves by springs and wheels as doth a watch) have an artificial life?
Thomas HobbesThe 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 HobbesTrue and false are attributes of speech not of things. And where speech is not, there is neither truth nor falsehood. Error theremay be, as when we expect that which shall not be; or suspect what has not been: but in neither case can a man be charged with untruth.
Thomas HobbesEmulation is grief arising from seeing one's self, exceeded or excelled by his concurrent, together with hope to equal or exceed him in time to come, by his own ability. But envy is the same grief joined with pleasure conceived in the imagination of some ill-fortune that may befall him.
Thomas Hobbes
