But I'm not wedded to that. I just see no compelling evidence to support a non-reductionist view. The universe, from all evidence, seems to emerge from basic rules of nature, many of which we understand very well and to a very high degree of accuracy.
I invite you to grab Murray Gell-Mann's TED talk off the TED site. You can download it and watch it at your leisure. He explains the principles better than I can on these forums.
Concerning plausibility, that's a pretty strong requirement in science. New science always fits in with the existing theories. It's been that way since the birth of modern science, basically Galileo. There are few exceptions, possibly Darwin, but even he wasn't the first to talk about evolution.
New theory fits like a jig saw puzzle piece into the existing body of theory. That just seems to be the way nature is arranged. And mother nature is the final arbiter to what is true, not any personal bias. In other words, nature seems to be reductionist, it's not anything I or anybody else is trying to imprint on her.
