Harry Frankfurt

67 pages, published in 2005, became a surprise bestseller. 

one of the salient features of our culture is that there is so much bullshit. 

everyone knows this.

each of us contribute 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 phenomena has not aroused much deliberate concern, nor 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 - Harry Frankfurt.
