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 ArendtEven though we have lost yardsticks by which to measure, and rules under which to subsume the particular, a being whose essence is a beginning may have enough of origin within himself to understand without preconceived categories and to judge without the set of customary rules which is morality.
