The Whole Argument, on One Page
If you have five minutes, this is everything. Each linked term goes deeper. The book goes deepest.
The setup
Almost no one asks what exactly ends when you die. The answer most people assume is "everything," and that answer is wrong. The proof is mundane. The atoms in your body are continuously replaced. The you that started elementary school is made of completely different physical material from the you reading this. And yet you are still you.
So you are not your atoms. You are something else. The book argues you are the pattern they form: the structure and functioning of your brain.
What that pattern produces
That pattern produces consciousness. Mainstream neuroscience already accepts this. It is not a controversial claim. The book just follows the claim further than almost anyone else does.
Within consciousness, there is something more specific: the quality of being yours. The book gives this its own word, ixperiencitness. It is the "you-ness" of your experience. It is what would be missing if a perfect copy of you walked into the room. The copy would be conscious, but it would not be experiencing your consciousness.
Three premises
Three claims. Each one is already accepted by mainstream science on its own:
- Production. Brain structure produces consciousness.
- Substrate independence. The same structure produces the same consciousness, regardless of which atoms it is built from.
- Recurrence. Patterns can be reproduced. They are not tied to one moment in space and time.
Once you accept all three, the conclusion follows. Your conscious existence cannot be permanently ended by the breakdown of one body.
Two deaths
External death and experiential death are not the same event. From the inside, you can never experience non-existence. There is always a next conscious moment from your perspective, even if that moment is in a different body at a different time. This is not mysticism. It is what the three premises imply.
The conclusion
Your ixperiencitness recurs. Maybe in a continuing body. Maybe in a perfect copy. Maybe in an enhanced version, or a simulated medium, or a body that arose independently somewhere else in the universe at some other time. The book calls this superimmortality to distinguish it from older, weaker concepts of immortality. You are not stuck in one life. You are supermortal. You die many times, and you live many times.
Where to go next
Pick a route:
- The Argument in 10 Concepts. The same case in more rigorous form.
- Thought Experiments Tour. The cases that test your intuitions about identity.
- Replicas. The taxonomy of bodies that produce your consciousness.
- The Book. Chapter previews from the full text.
Or if you want the whole thing, the book is the whole thing:
