Men are not therefore put to death, or punished for that their theft proceedeth from election; but because it was noxious and contrary to men's preservation, and the punishment conducing to the preservation of the rest, inasmuch as to punish those that do voluntary hurt, and none else, frameth and maketh men's wills such as men would have them.
Thomas HobbesSo 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.
