July 8. I'm pretty sure that out of all the belief systems in human history and prehistory, there's only one that does not believe in an afterlife: physicalism, a.k.a. materialism: the belief that mindless matter is the fundamental reality.
And yet, physicalism has been undermined again and again by its own experiments. The word "quantum" is thrown around a lot, and I think this is an example of the saying "The finger pointing at the moon is not the moon." The double-slit experiment is just a signpost, rising from physicalism, and pointing to psychism. It tells us that the fundamental reality is not the particle but the observer, that time and space and number and measure are like the rules for a game played by pure consciousness. You don't have to know anything about quantum physics to understand this. Leibniz (who also invented calculus) understood it 300 years ago with his concept of monads:
The only things that could be called real were utterly simple beings of psychic activity "endowed with perception and appetite." The other objects, which we call matter, are merely phenomena of these simple perceivers.
Going back to the afterlife, what happens to the monad that's now being you, when it leaves the game? There's a lot of evidence on this subject from near-death experiences. A common objection to NDEs is that those people must not have been really dead, but this is an example of the No true Scotsman fallacy. People have been dead by every clinical definition, including having no brainwaves, sometimes for multiple days, and have come back with reports.
These reports have less in common than you've been told. Not everyone goes down a tunnel to the light, or is greeted by family members. I heard about a guy who was greeted by John Belushi in a bee costume. Some NDEs are so out-there that the person can't even explain them in words. But this Reddit post generalizes from the bulk of reports: What The Afterlife is Like, Based on 100+ Years of Evidence.
Personally I have a variation of Pascal's wager. Pascal was like, "What if the wrathful Christian God is real? I'd better believe in him just in case." I'm thinking, "What if we get to write our own afterlife?" Surely it's not that simple, but what have I got to lose, if I imagine it in detail? This Reddit thread includes my answer from six years ago: If you actually go to a paradise after you die, but the paradise automatically is set up in a way which will be the absolute maximum best and pleasing experience for you, how would your paradise be like?
So, if the afterlife is so great, what are we doing in this dystopia? There are many answers to this question, which I'm not going to get into, but another thing that NDE-ers generally agree on is that suicide is a bad idea. I can make sense of this with the metaphor of walking out of a movie. You might walk out if it's near the end, you're not enjoying it, and you're ready to go home. But you don't want to walk out during the most intense part -- that's why you went to the movie in the first place.
July 10. A few loose ends on the afterlife.
Epistemological: I don't trust hypnotic regression nearly as much as in-the-wild NDEs. The way reality works, the hypnotist will influence results even with no leading questions.
Ontological: The total of all reports available to us must still be a drop in the ocean of out-of-this-world realms. Eric comments, "Those NDEs have been in the bardo for what? 20 minutes, and now they know all about it?"
Practical: Thinking about the afterlife is a distraction from focusing on the here and now, in which each moment is potentially heaven.
Political: If this world is, metaphysically, a place of pain and hardship, that's why the left can never win. At the same time, this is a place of flux and upheaval where authoritarianism can never hold on for long.
Theological: The biggest perk of physicalism is that you don't have to explain evil, because it's all meaningless. If there's mind behind matter, then why has mind done all this shit? This is usually framed as "How can a benevolent and omnipotent God allow evil?" But I don't believe in that kind of deity. I was raised Catholic, and by its terms I no longer believe in God the Father, but God the Holy Spirit totally makes sense. The benevolence of the universe is omnipresent but subtle. It's like the ocean wearing away rocks, or like the house advantage in gambling. Evil gets a lot of wins, but inevitably, reality bends toward playfulness, aliveness, and feeling good for everyone.
