The art of reasoning becomes of first importance. In this line antiquity has left us the finest models for imitation; I should consider the speeches of Livy, Sallust, and Tacitus, as pre-eminent specimens of logic, taste, and that sententious brevity which, using not a word to spare, leaves not a moment for inattention to the hearer. Amplification is the vice of modern oratory.
Thomas JeffersonGive 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.
Thomas JeffersonWhenever you are to do a thing, though it can never be known but to yourself, ask yourself how you would act were all the world looking at you, and act accordingly.
Thomas Jefferson
