When we think about ourselves, when we try to know ourselves … we use the knowledge of us which other people already have. We judge ourselves with the means other people have and have given us for judging ourselves. Into whatever I say about myself someone else’s judgment always enters. Into whatever I feel within myself someone else’s judgment enters.… But that does not at all mean that one cannot have relations with other people. It simply brings out the capital importance of all other people for each one of us.
