"People think that a liar gains a victory over his victim. What I've learned is that a lie is an act of self-abdication, because one surrenders one's reality to the person whom one lies, making that person one's master, condemning oneself from then on to faking the sort of reality that person's view requires to be faked. And if one gains the immediate purpose of the lie - the price one pays is the destruction of that which the gain was intended to serve."

~p.788 of Atlas Shrugged by Ayn Rand
