There is no outward sign of politeness which has not a deep, moral reason. Behavior is a mirror in which every one shows his own image. There is a politeness of the heart akin to love, from which springs the easiest politeness of outward behavior... Politeness is not always a sign of wisdom, but the want of it always leaves room for the suspicion of folly.
We enter our studies, and enjoy a society which we alone can bring together. We raise no jealousy by conversing with one in preference to another; we give no offense to the most illustrious by questioning him as long as we will, and leaving him as abruptly. Diversity of opinion raises no tumult in our presence: each interlocutor stands before us, speaks or is silence, and we adjourn or decide the business at our leisure.
