In a world that is essentially false, truthfulness would be an antinatural tendency: such a tendency could have meaning only as a means to a higher power of falsehood. In order for a world of the true, of being, to be invented, the truthful man would first have to be created (including the fact that such a man believes himself 'truthful'). (nietzsche 'will to power' : 292)

Truthful words are seldom pleasant (saying).
