"Since we always act into a web of relationships, the
consequences of each deed are boundless, every action touches off not only a
reaction but a chain reaction, every process is the cause of unpredictable new
processes.
In acting, […], it is indeed true that we can really never
know what we are doing.
And […] though we don’t know what we are doing when we are
acting, we have no possibility ever to undo what we have done."(1)
