First you kill the bad people, then you go to school.
Or, as John Adams wrote
I must study politics and war that my sons may have liberty to study mathematics and philosophy. My sons ought to study mathematics and philosophy, geography, natural history, naval architecture, navigation, commerce and agriculture, in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry and porcelain.
John Adams to Abigail Adams, [post 12 May 1780]
