To brand man with infamy, and let him free, is an absurdity that peoples our forests with assassins. [Fr., Rendre l'homme infame, et le laisser libre, est une absurdite qui peuple nos forets d'assassins.]

The condition upon which God hath given liberty to man is eternal vigilance.

The price of freedom is eternal vigilance.

The condition upon which God hath given liberty to man is eternal vigilance.

Evil prospers when good men do nothing.
