Liberty is the only thing worth fighting for.
We don't inherit the earth from our ancestors; we borrow it from our children.
译文：事前不研讨，遇变难以应对;军队不训练，作战难以取胜。强调未雨绸缪的重要性。
——《致鲁赛尔函》（1906年11月8日）
The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.
