So that in the nature of man, we find three principal causes of quarrel. First, competition; secondly, diffidence; thirdly, glory. The first maketh men invade for gain; the second, for safety; and the third, for reputation. The first use violence, to make themselves masters of other men's persons, wives, children, and cattle; the second, to defend them; the third, for trifles, as a word, a smile, a different opinion, and any other sign of undervalue, either direct in their persons or by reflection in their kindred, their friends, their nation, their profession, or their name.
Thomas HobbesIf men are naturally in a state of war, why do they always carry arms and why do they have keys to lock their doors?
Thomas HobbesAmbition, and Covetousnesse are Passions that are perpetually incumbent, and pressing.
