I think another high point in the audio version - again with the accent, you'll have to imagine it if you haven't heard it - is when he discusses agnosticism/atheism with reference to Bertrand Russell's teapot analogy.
He says something along the lines of: We cannot prove that there is not a teapot in between the orbits of earth and mars so strictly speaking we should all be agnostic with regard to teapots. In practice though we are all A-teapotists.
A-teapotists - in that accent, priceless.
Do you know, threads like this just aren't the same without brother apostate dumping 10 pages of cut and paste in somewhere
