Calling all metaphysicians! Would you like a simplified explanation of the multiverse interpretation of quantum mechanics? Would you like it to be presented to you using Super Mario World? Well, look no further.

Interesting Philosophical Applications
Metaphysical Modality
Some people think that the parallel universes in the multiverse hypothesis could play the role of Lewisian Possible Worlds. I have serious doubts about this. The main issue is that the multiverse that some physicists take seriously probably won't have enough universes to represent all metaphysical possibility.

The Fine-Tuning Argument for the Existence of God.
One possible response to The Fine-Tuning Argument for the Existence of God involves appealing to some kind of Multiverse Hypothesis. (Shameless plug - Check out Beebe's presentation of the Fine-Tuning Argument over at Young Philosophers)

Anyway, whatever your thoughts about the potential philosophical applications of the multiverse hypothesis - the video is pretty excellent. Enjoy.

In the last few hours, I've stumbled on quite a few cool bits of philosophy...

1. Mike Almeida has a pretty interesting post on Multiverse responses to a variety of versions of the Problem of Evil here.

2. Carrie Jenkins just suggested that we might be able to handle Kripkenstein Undetermination Worries in a (roughly) analogous way that epistemologists might handle Drestke Cleverly Disguised Mule cases.

3. Lewis Powell just pointed out some very cool papers by Mark Schroeder. The one I've been reading through argues that a common argument against Divine Command Theory generalizes to just about any moral theory. We then get a diagnosis of where the original argument goes wrong. I'm only about half-way through the paper, but it's a good read so far. Here's the link.
