I'm a proud believer in reality. That's my god, now that I've deconverted from religious belief: natural reality.
His philosophical conclusions don't come out of thin air. They're grounded in fundamental understandings of modern science.
Below are some of those understandings. If anyone reading this blog post wants to challenge them, describe your reasons in a comment. Hey, who knows? Maybe you know more about natural reality than the world's scientists.
If so, a Nobel prize could await you -- if you have solid evidence for your hypothesis that goes beyond a Church of the Churchless blog post comment.
If not, these scientific understandings constitute a knowledge fence within which any attempt to place God, spirit, soul, heaven, or such must contend. Meaning, any religion, form of spirituality, or mystical teaching has to conform to these facts to have a chance of being believable.
Understand: by "facts" I don't mean unchallengeable truth. Science doesn't work that way. Scientific facts always are open to modification as better knowledge about reality becomes available.
But given our current state of scientific understanding -- which is hugely more accurate than religious conceptions of the cosmos -- these are solid facts about the universe that, as Rosenberg says in his book's title, are the best guide to reality for those unwilling to accept fanciful religious theologies.
(3) "All the processes in the universe, from atomic to bodily to mental, are purely physical processes involving fermions and bosons interacting with one another." (A Rosenberg quote)
(4) Evolution through natural selection explains how life has come to be as it is on Earth.
(5) Core morality enabled early humans to better survive by cooperating with each other, an evolutionary advantageous trait that persists today in us social creatures.
(6) Determinism, which is different from "fate," rules the universe at levels of reality above the quantum realm.
(7) The mind/brain produces consciousness, and does everything else, through complex interactions of neural circuits.
(8) There is no non-material self within the human body, just physical mind/brain goings-on.
