because they hate to be lied to, but like to lie...

"Because they hate to be lied to, but like to lie, they love to find things with the help of truth, but hate to be found out by it. But this is the revenge truth takes on those men unwilling to be found out by it: It not only finds out the truth about them but prevents them from finding it out. To this, even this, is the human mind reduced, to this blind, weak state, that it wants to hide its foul vileness from others, but wants nothing hidden from it." > St. Augustine, Confessions
