The only vice that cannot be forgiven is hypocrisy. The repentance of a hypocrite is itself hypocrisy.
William HazlittThe thing is plain. All that men really understand, is confined to a very small compass; to their daily affairs and experience; to what they have an opportunity to know, and motives to study or practice. The rest is affectation and imposture.
William HazlittAn honest man speaks the truth, though it may give offence; a vain man, in order that it may.
