" The chief non-human species that practice war, with organized armies engaging in deadly combat, are certain varieties of ant. Those social insects some sixty million years ago had invented all the major institutions of 'civilization,' including 'kingship' (actually, queenship), military conquest, the division of labor, the segregation of functions and castes, to say nothing of the domestication of other species and even the beginnings of agriculture. Civilized man's chief contribution to this anthill complex was to add the powerful stimulant of irrational fantasy. "
