“The child who defines a lie as being a "naughty word" knows perfectly well that lying consists in not speaking the truth. He is not, therefore, mistaking one thing for another, he is simply identifying them one with another by what seems to us a quaint extension of the word "lie."”

— Jean Piaget

“…it seems to me that it's up to all of us to try to tell the truth, to say what we know, to say what we don't know, and recognize that we're dealing with people that are perfectly willing to, to lie to the world to attempt to further their case and to the extent people lie of, ultimately they are caught lying and they lose their credibility and one would think it wouldn't take very long for that to happen dealing with people like this.”

“While the Christian apostles preached their ideal in the open, the Talmud hides; and its two appendages, the Kahal and Freemasonry, are even more invisible. The three of them use, in order to remain in the dark, a scabrous and accursed means, namely the lie. In other words, the lie is the basis of the system used by Jews, to whom one can say.. 'You speak, therefore you be.' But the lie has a mortal enemy, namely the truth. For truth is the distinctive trait of Christianity.”
