“It is of great importance to set a resolution, not to be shaken, never to tell an untruth. There is no vice so mean, so pitiful, so contemptible; and he who permits himself to tell a lie once, finds it much easier to do it a second and a third time, till at length it becomes habitual; he tells lies without attending to it, and truths without the world’s believing him. This falsehood of the tongue leads to that of the heart, and in time depraves all its good disposition.” —Thomas Jefferson (1785)
