The Grand Design. We're reading together and then wil get together over coffee to discuss it. For me it's one of those books I need to read for myself, especially since it challenges (seemingly) the Fine-Tuning Argument for God's existence, and argument I and others continue to find persuasive.
Yes, it is persuasive. I've had students in my philosophy of religion courses turn from agnosticism and atheism to theism after being presented with it.
