Truth, Lies, and Bullshit

On Bullshit by Harry G. Frankfurt is an interesting essay on, well, bullshit. Basically, in grandiose terms, Frankfurt defines bullshit as communication that has no regard for the truth, but may not necessarily be a lie. From the essay:

Through excessive indulgence in [bullshitting], which involves making assertions without paying attention to anything except what it suits one to say, a person's normal habit of attending to the ways things are may become attenuated or lost. ... [The bullshitter] does not reject the authority of truth, as the liar does, and oppose himself to it. He pays no attention to it at all. By virtue of this, bullshit is a greater enemy of the truth than lies are.
