I've been actively working on this problem for 6 years. More on this soon.
I've read a lot on the topic of rationality through the years but I want to get down my thoughts on rationality as such. More to come...
This seems like a straightforward question about the nature of consciousness but I don’t think we need to know anything about consciousness specifically to answer this question. Nothing, that is, beyond the premise that consciousness is a physical phenomenon and nothing else like spirit stuff. There wouldn’t be much reason to engage with this question after all if one were not a physicalist.
