Tact is good taste in action.
It is only love that has already fallen sick that is killed by absence.
We only make a dupe of the friend whose advice we ask, for we never tell him all; and it is usually what we have left unsaid that decides our conduct.
It is easier to die for a cause than to live for it.
It is easier to win love than to keep it.
... see well how it often befalls that to rise to the topmost degree would make it seem that the abyss is on high.
