In 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 Jefferson, Henry Augustine Washington (1859). “The Writings of Thomas Jefferson: Correspondence”, p.378
