Here's the Amazon link to Frankfurt's book.

Jane Eisner, The Philadelphia Inquirer
"The trouble with bullshit is that it undermines cultural respect for the truth. And what else does a democracy have? "

Product Description:
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. We have no clear understanding of what bullshit is, why there is so much of it, or what functions it serves. And we lack a conscientiously developed appreciation of what it means to us. In other words, as Harry Frankfurt writes, "we have no theory."

I'm amazed people are defending this. The quote from The Inquirer ought to be enough to put them off. It reads like Scalia.

The discrete Stalinism of good intentions.
