"One of the most salient features of our culture is that there is so much bullshit. Everyone knows this. Each of us contributes his share. But we tend to take the situation for granted. Most people are rather confident of their ability to recognize bullshit and to avoid being taken in by it. So the phenomenon has not aroused much deliberate concern, or attracted much sustained inquiry. In consequence, we have no clear understanding of what bullshit is, why there is so much of it, or what functions it serves".On Bullshit is an essay by philosopher Harry Frankfurt. Originally published in the journal Raritan in 1986, the essay was republished as a separate volume in 2005 and became a nonfiction bestseller.In the essay, Frankfurt sketches a theory of bullshit, defining the concept and analyzing its applications. In particular, Frankfurt contrasts bullshitting and lying; where the liar deliberately makes false claims, the bullshitter is simply uninterested in the truth.Rather, bullshitters aim primarily to impress and persuade their audiences. Whereas the liar needs to know the truth the better to conceal it, the bullshitter, interested solely in advancing his own agenda, has no use for the truth. By virtue of this, Frankfurt claims, "bullshit is a greater enemy of the truth than lies are."
