" The Revolution was another of the darkest, most uncertain of times and the longest war in American history, until the Vietnam War. It lasted eight and a half years, and Adams, because of his unstinting service to his country, was separated from his family nearly all that time, much to his and their distress. In a letter from France he tried to explain to them the reason for such commitment. I must study politics and war [he wrote] 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 paintings, poetry, music, architecture, statuary, tapestry, and porcelain.
