The book starts off with an interesting idea, why do people 'bull
shit', hoping for a decent answer, doesnt turn out that way. It
spends nearly all the book talking about what is bullshit (is it
lying, humbug, etc). But it doesn't address the issue head on until
the last three (short) pages. Right when the auther starts to make
some interesting points the book ends. It would be nice to see
Prof. Frankurt right a revised version with a bit more substance to
it.
One 'silver lining' is that the book may do what it intends to do,
let the reader figure out 'why we bullshit' on their own, the book
certainly puts ideas in your mind on the topic, but it doesnt
explicitly say so.
