The possible redemption from the predicament of irreversibilityโโof being unable to undo what one has doneโโis the faculty of forgiving. The remedy for unpredictability, for the chaotic uncertainty of the future, is contained in the faculty to make and keep promises. Both faculties depend upon plurality, on the presence and acting of others, for no man can forgive himself and no one can be bound by a promise made only to himself.
Hannah ArendtPsychologically speaking, one may say that the hypocrite is too ambitious; not only does he want to appear virtuous before others, he wants to convince himself.
Hannah Arendt
