meta
the domain of knowledge about knowledge. meta is the reflexive turn: how do we know what we know? what counts as evidence? how has understanding changed over time? epistemology, methodology, history, the philosophy of science — meta is the domain that watches the other 20 domains and asks whether they are doing their job
for cyber, meta is self-awareness. the protocol must not only store knowledge but evaluate it. cyberank is a meta-operation: it computes which particles are relevant given the graph's structure. the crystal specification (Section 10) requires validation — ablation testing, irreducibility proofs — and that is meta applied to itself. a superintelligence without meta is an oracle that cannot question its own answers
scope
epistemology — knowledge, knowledge theory, truth, causation, correlation, observation, probability, explicit knowledge, implicit knowledge, deep understanding. what knowledge is, how it is justified, and where it fails. the crystal's four formalizations of irreducibility (MDL, category-theoretic, information-theoretic, ablation) are epistemological choices
methodology — science, statistics, sampling, formal verification, experiment design, peer review. the tools for producing reliable knowledge. cyber/proofs — the protocol's proof system — is methodology for computation
history — time/history, Bronze Age, Iron Age, Neolithic revolution, Industrial Revolution, Information Age, Renaissance, Cambrian explosion, geological time. the record of what happened and why. history is the empirical arm of meta — it shows how knowledge actually accumulated (and was lost)
reflexivity — metagraph, about this metagraph, knowledge graphs, knowledge completeness, knowledge topology, semantic core. knowledge about the graph itself. the cyber/metagraph page describes how the crystal relates to the full cybergraph, which is meta applied to cyber's own architecture
bridges
- meta → math: metamathematics — Kurt Goedel's theorems — shows what formal systems can and cannot prove about themselves
- meta → info: Shannon defined information precisely. information theory is meta applied to communication
- meta → lang: metalanguage is language about language. semantics is meta applied to symbols
- meta → spiri: values determine what counts as important knowledge. meta and spiri co-evolve
- meta → comp: computability theory asks what can be computed — meta about computation
- meta → cyber: the protocol is self-validating. cyberank and proof systems are meta-operations on the graph
