You can't talk your way out of a situation you acted you way into.
Progress occurs one apology at a time.
Apology is the most courageous gesture we can make to ourselves.
We value apology in the abstract, but turn our backs on it in practice.
One of the most useful tasks of apology is to bring home to us how keenly, honestly, and painfully past generations pursued aims that now seem to us wrong and disgraceful. It behooves us to consider if future geenrations will similarly regard the aims we most defend today.
Apology is not for the faint of heart, but then, neither is life.
