"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." 
12 May 1780 John Adams

一点心得：绝不接受文化习俗的统战，可以接受金钱物质的统战，条件是首先保证政治上的公正和道义。政治的本质是提供安全和保护，公正和道义的实现手段是暴力，暴力仅限于保卫自己的利益。
