The first is On Bullshit, by Harry G. Farkfurt. It's a tight little book, 15cm by 10cm, 68 pages, and it's about what it claims to be, a readable philosophical and prescriptive analysis of the nature bullshit, humbug, balderdash. It's been positively reviewed on Instapundit, NPR All Things Considered, and The Daily Show with Jon Stewart.
I agree with the positive reviews, I've been much enjoying it.
As soon as I done reading it, I'm going to tag it into BookCrossing, and set it free
