" Should it happen that the community where they are born be drugged with long years of peace and quiet, many of the high-born youths voluntarily seek those tribes which are at the time engaged in some war; for rest is unwelcome to the race, and they distinguish themselves more readily in the midst of uncertainties: besides, you cannot keep up a great retinue except by war and violence … you will not so readily persuade them to plough the land and wait for the year’s returns as to challenge the enemy and earn wounds: besides, it seems limp and slack to get with the sweating of your brow what you can gain with the shedding of your blood. "

― Francis Fukuyama , The Origins of Political Order: From Prehuman Times to the French Revolution
