On Bullshit - Book by Harry Frankfurt (Princeton) (PDF)
On Bullshit is a 1986 essay, reprinted as a 2005 book, by philosopher Harry G. Frankfurt which presents a theory of bullshit that defines the concept and analyzes the applications of bullshit in the context of communication. Frankfurt determines that bullshit is speech intended to persuade without regard for truth. The liar cares about the truth and attempts to hide it; the bullshitter doesn't care if what they say is true or false, but rather only cares whether their listener is persuaded.
