Metametaphysics This reality has no explanation and it turns out to make sense. An ultimate explanation isn't unknown, it just doesn't exist
CORE ARGUMENT: Any explanation of why reality is *this* way (these laws, these constants, this history, when we can describe others) either contains something that favors this way over the alternatives, or it doesn't.
- If it doesn't, it's general: it would fit any content equally, so it can't say why this content is here. In such an explanation, "this" and "the alternatives" are placeholders: fill them with anything, and the explanation still runs.
- If it does, it's specific, and whatever does the favoring is itself part of reality. It can't explain itself, and there's nothing outside reality to explain it, so the question just moves to it, unanswered.
Ordinary explanations escape this because they borrow from outside what they explain: whales are warm-blooded because they're mammals, and being a mammal is a fact besides the warm blood. When the thing to explain is everything, there's no outside to borrow from.
Three premises carry it:
"Reality" means everything there is, so whatever candidate to explain it (laws, a multiverse, anything else) would already be one of the things there are.
Nothing explains itself. Either it's trivial (opium puts you to sleep because it has a sleep-inducing power), or it says a thing exists "by its nature," which leaves the nature unexplained.
Whatever makes a difference is specific. Even chance and choice need a menu: a lottery needs its tickets, and a chooser needs options and preferences.
Given those, it's a proof, not a guess: **no explanation of why reality is this way is possible.** A specific explanation assumes too much. A general one assumes too little: too little for a universe that assumes too much. Full argument here.
WHAT FOLLOWS:
- It's not a gap in our knowledge. The split is a fact about what explanations are, not a track record of the ones tried so far, so it covers candidates nobody has proposed yet. You know you're at the North Pole because every direction points south; you don't need to look past the edge seeking the north of the north pole.
- No answer is owed. "Why these constants?" is a real question, since we can describe others. But an answer can be owed only where one is possible, which is explanation's version of "ought implies can." So the bottom of reality isn't strictly brute (a fact that calls for an explanation and doesn't get one, like an unpaid debt). It's unexplainable: the question makes sense, no answer is possible, and nothing is missing.
- The edge isn't at the beginning of time. Whatever physics finds first (a Big Bang, a bounce, a parent universe) is one more piece of specific content. The edge where explanation runs out is as present now as it was 13.8 billion years ago. Leibniz's example: a geometry book that has always existed, each copy made from the one before. Every copy is explained, and nothing explains why the book says what it says.
Explanation doesn't rule what exists; it's a shadow that follows it. That's why it runs out at the bottom, and why nothing falls when it does.
IMMEDIATE OBJECTIONS:
- "A general explanation is still an explanation." Yes, but only of what our universe shares with every other one we can describe. "Nothingness was never an option" explains why there's something rather than nothing, but it's equally true of every describable universe, so it contains ours without explaining it, the way "the winning number is between 1 and a million" contains tonight's number without saying why it came up.
- "Isn't the argument itself general, so empty by its own standard?" Only if it claimed to explain why this world is this way. It explains why no such explanation is coming, which is meant to hold in every world. Likewise, a truth about every triangle is still a truth about this one.
- "Explain every part and you've explained the whole" (Hume's twenty particles; Paul Edwards's five people on a street corner). On the street corner, every reason eventually leads outside the group: the husband came for his wife, and she came for a warmer climate. In a chain that contains everything, endless or not, every explanation stays inside the chain. Again, Leibniz's example: a geometry book that has always existed, each copy made from the one before. Every copy is explained, and nothing explains why the book says what it says.
- "Every fact must have an explanation." For a rationalist, this conclusion is a scandal. But Kenneth Pearce has argued (2025) that the demand can be defended only if whatever ultimately makes the facts hold could, in exactly the same circumstances, have made something else hold instead, which puts it on the general side of the split. What's left is the disagreement over "ought implies can," and I don't claim to close it.
- "Everything never forms a whole." On a view that goes back to Michael Dummett, any collection of things you can talk about has something outside it, so no “everything” is ever final (Kit Fine, “Relatively Unrestricted Quantification,” 2006). Each “why this?” could then be answered one level up, with no last level. The cost is that the view seems impossible to state, since saying that no collection includes everything already seems to speak of everything (Timothy Williamson, “Everything,” 2003).
So the answer to "why this reality?" isn't hidden somewhere out of reach. There's no answer to find, and nothing is missing.
I'm curious where you think this breaks.
