In truth, politeness is artificial good humor, it covers the natural want of it, and ends by rendering habitual a substitute nearly equivalent to the real virtue.
Interpretation
Politeness often masks true feelings and can substitute for genuine kindness.
Thomas Jefferson suggests that politeness is a form of artificial good humor, which can disguise our natural inclination towards kindness. This facade of politeness may become so ingrained that it replaces authentic virtue, leading to a situation where true good humor is overshadowed by mere manners.
In practice
In a speech about social interactions, you could reference this quote to emphasize the importance of genuine kindness over mere politeness.

If something can corrupt you, you're corrupted already.
India was the motherland of our race, and Sanskrit the mother of Europe's languages: she was the mother of our philosophy; mother, through the Arabs, of much of our mathematics; mother, through the Buddha, of the ideals embodied in Christianity; mother, through the village community, of self-government and democracy. Mother India is in many ways the mother of us all.
For men are not equal: thus speaks justice.
The more powerful the class, the more it claims not to exist, and its power is employed above all to enforce this claim. It is modest only on this one point, however, because this officially nonexistent bureaucracy simultaneously attributes the crowning achievements of history to its own infallible leadership.
