Reason and free inquiry are the only effective agents against error. Give a loose to them, they will support the true religion by bringing every false one to their tribunal, to the test of their investigation. They are the natural enemies of error and error only. Had not the Roman government permitted free inquiry, Christianity could never have been introduced. Had not free inquiry been indulged at the era of the Reformation, the corruption of Christianity could not have been purged away.
Thomas JeffersonOur particular principles of religion are a subject of accountability to our god alone. I enquire after no man's and trouble none with mine; nor is it given to us in this life to know whether yours or mine, our friend's or our foe's, are exactly the right.
Thomas JeffersonIn every country where man is free to think and to speak, difference of opinion will arise from difference of perception, and the imperfection of reason; but these differences, when permitted, as in this happy country, to purify themselves by free discussion, are but as passing clouds overspreading our land transiently, and leaving our horizon more bright and serene.
Thomas JeffersonI am satisfied, and sufficiently occupied with the things which are, without tormenting or troubling myself about those which may indeed be, but of which I have no evidence.
Thomas JeffersonWhen we come to the moral principles on which the government is to be administered, we come to what is proper for all conditions of society. Liberty, truth, probity, honor, are declared to be the four cardinal principles of society. I believe that morality, compassion, generosity, are innate elements of the human constitution; that there exists a right independent of force.
