“He who does not lie does not know what truth is.”
“it is not only he who speaks contrary to what he knows who lies, but even more he who speaks contrary to what he does not know”
“The truth of what one says lies in what one does.”
“The truth about people does not lie in what they say but what they do.”
“Just because something isn't a lie does not mean that it isn't deceptive. A liar knows that he is a liar, but one who speaks mere portions of truth in order to deceive is a craftsman of destruction.”
“He who knows does not speak; he who speaks does not know.”
