Françoise Demore on Politeness, Deference, KindnessTrue Politeness (Benziger Brothers: 1897), p. 6.
There is, therefore, a difference between civility and politeness, a sort of gradation from the first to the second. To be polite means more than to be civil. A polite person is necessarily civil; but a person simply civil is not polite. Politeness, therefore, not only supposes civility, but adds to it. The latter is by communication with men what public devotion is in regard to God, an exterior and sensible testimony of the interior sentiments that ought to animate us; and even in this it is precious as inspiring exterior deference and kindness. It is an open confession of the esteem and benevolence that ought to reign within.
