If a nation expects to be ignorant and free, in a state of civilization, it expects what never was and never will be.
Thomas JeffersonThe most effectual means of preventing the perversion of power into tyranny are to illuminate, as far as practicable, the minds of the people at large, and more especially to give them knowledge of those facts which history exhibits, that possessed thereby of the experience of other ages and countries, they may be enabled to know ambition under all its shapes, and prompt to exert their natural powers to defeat its purposes.
Thomas JeffersonHe who permits himself to tell a lie once, finds it much easier to do it a second and third time, till at length it becomes habitual; he tells lies without attending to it, and truths without the world's believing him. This falsehood of the tongue leads to that of the heart, and in time depraves all its good dispositions.
Thomas Jefferson[If] the nature of ... government [were] a subordination of the civil to the ecclesiastical power, I [would] consider it as desperate for long years to come. Their steady habits [will] exclude the advances of information, and they [will] seem exactly where they [have always been]. And there [the] clergy will always keep them if they can. [They] will follow the bark of liberty only by the help of a tow-rope.
