Might be good to read this book:
"On Bullshit" (Harry G. Frankfurt)
Mary Park describes it as (editorial review from Amazon.com):
"One of the most salient features of our culture is that there is so much bullshit," Harry G. Frankfurt writes, in what must surely be the most eyebrow-raising opener in modern philosophical prose. "Everyone knows this. Each of us contributes his share. But we tend to take the situation for granted." This compact little book, as pungent as the phenomenon it explores, attempts to articulate a theory of this contemporary scourge--what it is, what it does, and why there's so much of it. The result is entertaining and enlightening in almost equal measure. It can't be denied; part of the book's charm is the puerile pleasure of reading classic academic discourse punctuated at regular intervals by the word "bullshit." More pertinent is Frankfurt's focus on intentions--the practice of bullshit, rather than its end result. Bullshitting, as he notes, is not exactly lying, and bullshit remains bullshit whether it's true or false. The difference lies in the bullshitter's complete disregard for whether what he's saying corresponds to facts in the physical world: he "does not reject the authority of the 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."
