On Bullshit

On Bullshit is a 2005 book (originally a 1986 essay) by American 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 cares only whether the listener is persuaded. Frankfurt's philosophical analysis of bullshit has been analyzed, criticized and adopted by academics since its publication.
