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 JeffersonThe main objects of all science, the freedom and happiness of man. . . . [are] the sole objects of all legitimate government. A plaque with this quotation, with the first phrase omitted, is in the stairwell of the pedestal of the Statue of Liberty.
