What is it to bullshit? Perhaps the best way to understand bullshitting is by comparing it to lying. So what is it to lie? The first thing to understand is that a lie is not the same as a false statement. Suppose I make a statement about something but my statement turns out to be false. It does not follow that I have lied. Suppose a latter-day Rip van Winkle wakes up from a long nap and, asked about the Dodgers, says, "They are a baseball team from Brooklyn." Has our man lied? Not at all. He simply hasn't kept up with 'recent' developments.
For a statement to count as a lie two conditions must be satisfied: (a) the statement must be false; (b) the statement must be made with the intention to deceive. These conditions are individually necessary and jointly sufficient. But what if someone states what he believes to be false with the intention to deceive, but it turns out that what he states is true? Isn't that also a lie? Not by the definition I just gave. So it looks as if we are in the presence of two concepts of lying. The concept just defined is the narrower and more usual concept. The other, broader concept, results by the deletion of condition (a).
