Here’s one for the discussion Alan and I had about quantization. It covers everything from the beginning all the way through until the line on this post, after which I start to ask Alan to give his own reason for why he thinks partially quantum mechanical theories are bad. I see that line as basically starting the conversation anew with my better understanding of what Alan means by partially/fully quantum mechanical theory, and if I was going to put it in the tree it would be a new tree.
