[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.
Thomas Jefferson... I am not afraid of priests. They have tried upon me all their various batteries of pious whining, hypocritical canting, lying and slandering. I have contemplated their order from the Magi of the East to the Saints of the West and I have found no difference of character, but of more or less caution, in proportion to their information or ignorance on whom their interested duperies were to be played off. Their sway in New England is indeed formidable. No mind beyond mediocrity dares there to develop itself.
Thomas JeffersonThe value of science to a republican people, the security it gives to liberty by enlightening the minds of its citizens, the protection it affords against foreign power, the virtue it inculcates, the just emulation of the distinction it confers on nations foremost in it; in short, its identification with power, morals, order and happiness (which merits to it premiums of encouragement rather than repressive taxes), are considerations [that should] always [be] present and [bear] with their just weight.
Thomas JeffersonA schism has taken place among the chemists. A particular set of them in France have undertaken to remodel all the terms of the science, and to give every substance a new name, the composition, and especially the termination of which, shall define the relation in which it stands to other substances of the same family.
Thomas JeffersonI join you therefore in branding as cowardly the idea that the human mind is incapable of further advances.
Thomas JeffersonThe evidence of [the] natural right [of expatriation], like that of our right to life, liberty, the use of our faculties, the pursuit of happiness, is not left to the feeble and sophistical investigations of reason, but is impressed on the sense of every man. We do not claim these under the charters of kings or legislators, but under the King of Kings.
