A couple of weeks ago I had a discussion with His Dagginess about whether he is an agnostic or an atheist. Strangely enough, I had always assumed he was an atheist but he sees himself as agnostic: that is, he believes that it is not possible to know whether there is a metaphysical being/force because our knowledge is limited to the physical universe.
Then, a couple of days ago I was listening to an ABC radio podcast of the Philosopher's Zone in which Pascal's Wager was briefly discussed. In brief (and perhaps not completely accurate) summary, the wager says that, logically, if you believe there is a small chance that there is a god -- no matter how infinitesimally small that chance is -- you really have no choice but to believe in God, because you have nothing to lose and everything to gain. I rushed home to tell Ms Nominative Determinism about it, so she could add it to her arsenal of weapons to try to convert her father. Naturally, she immediately tried to use it on me, but I told her there was no point, because I have decided that the probability of god existing is zero.
We both turned the new weapon on His Dagginess that evening, each hoping to convert him to our own side: Ms ND to her beliefs and me to my unbeliefs. Unfortunately, the Dagster also had a good argument. "I concede your point," he said, "but I think there is an equal probability of all forms of god existing, so now you have to convince me which one I should choose."
Sigh. Back to the drawing board. And I thought I had him there....
