It struck me as very worrying as a kid that god would give a test on how to live the result of which would have the most far-reaching personal consequences imaginable, and give pointers to some but not others. This was one of the many things in my quest to understand god that nobody else seemed to have any reasonable idea about, either. Nobody else seemed to have a problem with it, and after a couple of "mysterious ways" I just gave up asking. I mean, I couldn't even get a straight "I don't know" out of those people so why bother ...
That said, the music grated on my nerves but I just love seeing a defective argument eviscerated comprehensively. No matter what "side" it's on - if it's wrong it's got to go. Christians would use the exact same arguments against the wager if it were al-D?n al-??s?'s rather than Pascal's.
I always found the fact that Pascal goes from god to christian god without so much as a footnote; it just sticks out like an X-Wing in the battle for Minas Tirith. It really makes you wonder (and if it doesn't, it should) if Pascal was so blinded by his will to believe or whether he was purposefully creating propaganda.
