"They used to call the devil the father of lies. But for someone whose sin is meant to be pride, you'd think that lying would leave something of a sour taste. So my theory is that when the devil wants to get something out of you, he doesn't lie at all. He tells you the exact, literal truth. And he lets you find your own way to hell."
But ’tis strange;
And oftentimes, to win us to our harm,
The instruments of darkness tell us truths,
Win us with honest trifles, to betray's
In deepest consequence—

"Do you know what a Dalek is, Van Statten? A Dalek is honest. It does what it was born to do for the survival of its species. That creature in your dungeon is better than you."

Isn't it funny how during our various matches, I can tell you what my moves will be in advance, and still win?

"And when at last the police came by,
And when at last the police came by,
Her little pranks she did not deny.
To do so she would have had to lie,
And lying, she knew, was a sin, a sin,
Lying, she knew, was a sin."
—Tom Lehrer, "The Irish Ballad"
"Human. We Ur-Quan never lie. NEVER! It is a weakness to lie and, as you have noticed, the Ur-Quan are not weak!"

"I am many things, Templar, but I am no liar. With all the secrets I have learned over the centuries, the truth is far more entertaining. For example, would you like to hear of the true origin of your order?""
