I think that it is useless to fight directly against natural weaknesses. One has to force oneself to act as though one did not have them in circumstances where a duty makes it imperative; and in the ordinary course of life one has to know these weaknesses, prudently take them into account, and strive to turn them to good purpose; for they are all capable of being put to some good purpose.

Our patriotism comes straight from the Romans. This is why French children are encouraged to seek inspiration for it in Corneille. It is a pagan virtue, if these two words are compatible.
