A philosopher parses lying vs BS-ing

Liars know and care about the truth --- after all, they work hard to conceal it.

But:

"The B.S.-er can be more dangerous than the liar because he or she won’t even agree, as the liar does, that facts exist."

"For the B.S.-er all bets are off: “[H]e is neither on the side of the true nor on the side of the false. His eye is not on the facts at all, as the eyes of the honest man and of the liar are.’’
