I think Daniel Dennett's book "Elbow Room" is an excellent defense of compatibilist free will and why it is the only kind worth having.Great suggestion. The wikipedia page was fairly informative, but I'll probably buy the book anyway. From what I gather, he believes the kind of free will worth wanting is the appearance (or illusion) that we can control our behavior to a large extent. I agree with him that we don't want to be uncaused causes (or uninfluenced influences) of events, which is how quantum particles appear to behave (i.e., stochastically)."Everything that is physically possible" is not very well defined. And in any case it doesn't follow that in an infinite universe everything possible must happen infinitely many times. For example it might be that almost all universes are uninteresting and barren and only a finite number are interesting like ours.Technically I think you are right. However, I was only talking about an infinite universe likes ours that operates in accordance with the laws of quantum physics. Let me explain by using what I've read of Victor Stenger and Brian Greene. There are three ingredients in the argument that all quantum-physical possibilities in our universe happen infinitely many times. 1) There is an infinite number of Hubble volumes in our universe, which are all casually disconnected (as the theory of inflation implies). 2) There is a limit on how much matter and energy can exist within a region of space of a given size, such as a Hubble volume. 3) There is only a finite number of possible configurations of matter, due to the Uncertainty Principle. I can explain any of these ingredients in more depth if you'd like me to, but I hope you see that they lead to the conclusion that all quantum-physical possibilities in our universe are realized infinitely many times.

`No they don't. There's an implicit assumption that what happens in these other universes`

`has the same or similar probability distribution as we observe in ours. A reasonable`

`assumption, but not a logically necessary one. I think it's what Bruno means by`

`"homogeneous". It's logically possible that all but a finite number of these universes`

`are just exact copies of the same completely empty universe, for example.`
