Radiant Cool by Dan Lloyd is rich and tasty philosophical fiction with the subtitle A Novel Theory of Consciousness. I'm still reading it and am reading it slowly, not only to savor it, but also because there is much to ponder on the way. A few treats so far:
1. ...time leaves its mark on my now.
2. ...harmonics of meaning attach to every object in the knowable universe.
3. The instant has to be long enough for consciousness.
4. Meaning takes time.
5. 100 trillion modifiable synaptic connections in the brain
6. How we love the hidden order...moronic chaos of reality transfigured.
8. Multiple drafts model of consciousness (See Daniel Dennett's Consciousness Explained.)
9. The mind is a text.
10. The text is stored in memory, accessed and updated all the time, even in our dreams.
Dennis Cass's Head Case is a much lighter approach to mind and consciousness, as his subtitle suggests: How I Almost Lost My Mind Trying to Understand My Brain.
