I find that Sam Harris is always interesting, even when I disagree with him (and lots of people disagree with him about lots of things). He has a post up on his site about Jonah Lehrer. In response to the Lehrer scandal, he has made his short ebook Lying available for free as a PDF for the rest of the week. You’ll find a link to it in the Lehrer post. I have started reading it, and his position on lying is pretty clear — he’s agin it. My sense is that Harris is not an especially deep thinker, but he is a clear and graceful writer, so you may want to check out his book — it’s only about 60 pages.
I also have Harris’s book Free Will on my e-queue. He’s not necessarily agin free will, but I’m pretty sure he doesn’t think it exists.
