I have a post at my blog about the meaning of saying that a religion is true or false where I discuss this interview. Basically I think he thinks that the practice of Judaism is good for him, and, at least for him, does not involve saying much about the world. That is clear from things like this:
"Religion is very different from science. The main part of religion is not about the way that we model the real world. I am purposely using the word "model." Religion is an experience, mainly an emotional and aesthetic one. It is not about whether the earth is 5,765 years old. When you play the piano, when you climb a mountain, does this contradict your scientific endeavors? Obviously not. The two things are almost - though not quite - orthogonal. Hiking, skiing, dancing, bringing up your children - you do all kinds of things that are almost orthogonal to your scientific endeavor. That's the case with religion also. It doesn't contradict; it is orthogonal."
Basically he is saying that his religion is a practice, not a belief. To the extent that it involves saying things about reality, those are mostly metaphorical or something similar.
Just came across this interview with Robert Aumann. On pgs. 20-27 he describes why and how he believes in Orthodox Judaism. I don't really understand what he's saying. Key quote (I think):
Anybody have a clue what he means by all this? Do you think this is a valid way of looking at the world and/or religion? If not, how confident are you in your assertion? If you are very confident, on what basis do you think you have greatly out-thought Robert Aumann?
Please read the source (all 7 pages I referenced, rather than just the above quote), and think about it carefully before you answer. Robert Aumann is an absolutely brilliant man, a confirmed Bayesian, author of Aumann's Agreement Theorem, Nobel Prize winner, and founder / head of Hebrew University's Center for the Study of Rationality. Please don't strawman his arguments or simply dismiss them!
