Hi Ken, thanks for your thoughts and questions. On panpsychism I would recomend reading Yitzhak Melamed (who I think is the foremost living Spinoza scholar) and Michael Della Rocca. If you fish around on Academia.edu you can find some interesting stuff. I have an essay where I go into it a bit too- I'll send a link to it here when I have a chance. With regards to self-organizing complexity, that's an involved, fascinating and key question. In short I think God, as Spinoza understands it, creates everything possible to create- everything that flows naturally from the nature of its own being. I think this naturally gives rise to complex, self-aware organisms, as well as many other things. Spinoza is decidedly anti-teleological as I'm sure you are aware.
