" Underneath the shifting sands of the struggle between two little Greek states [Thucydides] had caught sight of a universal truth. Throughout his book, through the endless petty engagements on sea and land which he relates with such scrupulous care, he is pointing out what war is, why it comes to pass, what it does, and, unless men learn better ways, must continue to do. His History of the Peloponnesian War is really a treatise on war, its causes and its effects. "
