On March 24th of this year, Cameron Bertuzzi’s channel on YouTube, Capturing Christianity, streamed a discussion between William Lane Craig and Alex Malpass. Nominally, the topic of debate was “Did the universe begin to exist?” However, their actual discussion was quite a bit more focused onto two very particular subjects. In part one of this review, we’ll look at the discussion of whether actual infinites are metaphysically possible. In the forthcoming part two, we’ll discuss the manner in which actual infinites are constructed.
As I am keenly interested in these particular questions, I was very excited for this discussion. I’ve discussed my contention with Dr. Craig’s treatment of the mathematics of infinity on a few occasions (most directly, here and here) but this particular debate brings forth some issues with which I have not previously engaged.
