Another entry in their Atoms & Eden series. This time it's up to Lewis Wolpert to remind everyone that we are a product of our biology, and if we have certain beliefs there's probably a biological explanation for them. Like for instance, our ability to understand Cause and Effect and extrapolate big theories about causation from little instances we see in everyday life (like tool-making). I apparently also need to read up on Scottish philosopher David Hume.
The letters section is highly entertaining as well. Count how many times the religious folks pretend to be a) bored by the argument and b) accuse scientists of being closed minded. Heh.
