"By himself, man adjusts everything to his own comfort. By himself, he is an irresistible liar. For he never says anything truly unpleasant to himself without instantly counterbalancing it with something flattering. The sentence [aphorism] from the outside has an impact because it comes unexpectedly: one does not have any counterweight ready for it. One helps it with the same strength one would have met it with in other circumstances."
