The New York Times (registration required) has recently posted a review regarding the book On Bullshit by Princeton philosopher and professor emeritus Harry G. Frankfurt.
It is interesting to note his observation that while honest people and liars both think they know (and respect) the truth, the bullshitters simply do not care what the truth is. They only care whether or not they are believed. The book is short and inexpensive and may be of interest to nanodot readers who are trying to separate fact from fiction from hype as nanotechnology develops.
