Avoid connecting yourself with characters whose good and bad sides are unmixed and have not fermented together; they resemble vials of vinegar and oil; or palletts set with colors; they are either excellent at home and insufferable abroad, or intolerable within doors and excellent in public; they are unfit for friendship, merely because their stamina, their ingredients of character are too single, too much apart; let them be finely ground up with each other, and they are incomparable.
Johann Kaspar LavaterThere are no friends more inseparable than pride and hardness of heart, humility and love, falsehood and impudence.
Johann Kaspar LavaterWho, in the midst of just provocation to anger, instantly finds the fit word which settles all around him in silence is more than wise or just; he is, were he a beggar, of more than royal blood, he is of celestial descent.
Johann Kaspar LavaterTrust him not with your secrets, who, when left alone in your room, turns over your papers.
