I'm not sure I see what you're getting at here. Recursiveness and circularity are pretty much the same thing. In that chapter I suggest, among other things, the absolute necessity of believing in something. I make this contention for purely rational reasons. Our physics, you see, is limited.
All physics ultimately fades into metaphysics.
There are edges to it, so to speak. It's out there, at the edges of physics, where we form and shape our belief sysems. We have to believe where knowledge fails. My personal belief is that Nothing is the source of everything. I would contend that it is absolute, but thereby replete with endless Possibility.
