One of the most salient features of our culture is that there is so much bullshit. Everyone knows this. Each of us contributes his share. But we tend to take the situation for granted. Most people are rather confident of their ability to recognize bullshit and to avoid being taken in by it. So the phenomenon has not aroused much deliberate concern, nor attracted much sustained inquiry.
Socrates called it rhetoric or sophistry — arguments that weren't really sound but that you could put over on people.
[The bullshit artist] "does not reject the authority of the truth, as the liar does, and oppose himself to it," he writes. "He pays no attention to it at all."
And this makes him, Mr. Frankfurt says, potentially more harmful than any liar, because any culture and he means this culture rife with [bull] is one in danger of rejecting "the possibility of knowing how things truly are."
