"On Lying" is my favorite thing by Sam Harris. It's short and pithy and worth a repeated listen every couple of years. I've tried to get into other stuff by him, by way of his collaborations with Richard Dawkins, but he doesn't seem to have the bright-eyed zeal of Dawkins. Perhaps this podcast can sway me?

As for philosophical zombies, I fall on the materialist side. "Like a human in all regards", including internally, to me means "human". My jabbering above is about whether human A is the same as human B, or human A one second later. :)
