According to the philosopher Harry Frankfurt, emeritus professor at Princeton University, bullshit is something that is constructed absent of any concern for the truth. This is quite different from lying, which implies a deep concern for the truth (namely, its subversion). Bullshit is particularly pernicious since the bullshitter adopts an epistemic stance that allows for a great deal of agility. For the bullshitter, it doesn’t really matter if he is right or wrong. What matters is that you’re paying attention.
