Emulation 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 HobbesDuring the time men live without a common power to keep them all in awe, they are in that conditions called war; and such a war, as if of every man, against every man.
Thomas HobbesThe praise of ancient authors proceeds not from the reverence of the dead, but from the competition and mutual envy of the living.
Thomas HobbesWhen it happeneth that a man signifieth unto us two contradictory opinions whereof the one is clearly and directly signified, andthe other either drawn from that by consequence, or not known to be contradictory to it; then (when he is not present to explicate himself better) we are to take the former of his opinions; for that is clearly signified to be his, and directly, whereas the other might proceed from error in the deduction, or ignorance of the repugnancy.
