The ordaining of laws in favor of one part of the nation, to the prejudice and oppression of another, is certainly the most erroneous and mistaken policy. An equal dispensation of protection, rights, privileges, and advantages, is what every part is entitled to, and ought to enjoy.

Benjamin Franklin, Emblematical Representations, 1774

Give up money, give up fame, give up science, give the earth itself and all it contains rather than do an immoral act. And never suppose that in any possible situation, or under any circumstances, it is best for you to do a dishonorable thing, however slightly so it may appear to you… From the practice of the purest virtue, you may be assured you will derive the most sublime comforts in every moment of life, and in the moment of death.

Thomas Jefferson, letter to Peter Carr, 1785
