It is impossible for someone to lie unless he thinks he knows the truth. Producing bullshit requires no such conviction. ... For the bullshitter, however, all these bets are off.... His eye is not on the facts at all, as the eyes of the honest man and of the liar are, except insofar as they may be pertinent to his interest in getting away with what he says. He does not care whether the things he says describe reality correctly. He just picks them out, or makes them up, to suit his purpose. Harry Frankfurt on Bullshit.
