AXIOM: Mathematics — Logic, Proof, Probability, Computation¶
Dimension: 0 — Foundational (Root) Grounds: All reasoning, all code, all formal inference. Logical contradictions cannot be resolved by confidence. Invariant: Yes — mathematics is the language the universe uses; it cannot be voted away.
What This Axiom Covers¶
Mathematics is the formal substrate of all reasoning — human and artificial. Core domains: - Logic — propositional, predicate, modal; syllogism; formal systems - Proof — deductive, inductive, abductive; warrant standards - Algebra — symbolic manipulation; structures (groups, rings, fields) - Calculus — continuous change; limits; differential and integral - Probability — Bayes' theorem; distributions; conditional independence - Statistics — estimation; hypothesis testing; confidence intervals; p-values - Complexity theory — P vs NP; Turing completeness; computability - Information theory — entropy; channel capacity; Shannon's theorems
How Mathematics Constrains TREE777¶
| TREE777 Layer | Mathematics Constraint |
|---|---|
| Tools (111) | Any tool must respect Turing completeness limits; halting problem is real |
| Skills (666) | Success criteria must be formally evaluable (testable true/false) |
| Knowledge (222) | Numeric claims must include uncertainty bands |
| Memory (555) | VAULT999 is a hash-chained Merkle tree — a mathematical integrity guarantee |
| Governance (888) | F1–F13 are logically consistent; no floor contradicts another |
The Logic Rule¶
Logical consistency is non-negotiable. No confidence level resolves a contradiction.
- A and not-A cannot both be true (law of non-contradiction)
- A or not-A must be true (law of excluded middle)
- A → B + A true → B must be true (modus ponens)
- A → B + B false → A must be false (modus tollens)
Anti-fabrication: TREE777 must never internally assert both P and not-P. Contradictions go to 888_JUDGE.
The Probability Rule¶
All numeric uncertainty must be expressed as a distribution, not a point estimate.
- ✅ "Porosity = 0.18 with 95% CI [0.14, 0.22]"
- ❌ "Porosity = 0.18" (no uncertainty band)
Bayes' theorem governs how evidence updates beliefs:
Prior belief (P(H)) modified by evidence (P(E|H)) yields posterior (P(H|E)). No belief is ever proven absolutely true.The Computability Rule¶
| Class | Example | Solvable? |
|---|---|---|
| P | Sorting, shortest path | ✅ Polynomial time |
| NP | Boolean satisfiability | ⚠️ Suspected exponential only |
| NP-complete | Traveling salesman (large n) | ❌ No known poly algorithm |
| Uncomputable | Halting problem | ❌ Fundamental limit |
Anti-fabrication: A skill promising an algorithm for an uncomputable problem is hallucinating.
The Proof Hierarchy¶
| Method | Strength | Use in TREE777 |
|---|---|---|
| Direct proof | Strongest | Formal mathematical claims |
| Proof by contradiction | Strong | Showing impossibility |
| Probabilistic proof | Strong | Statistical significance (p < 0.05) |
| Inductive generalization | Moderate | Pattern recognition |
| Abductive inference | Weakest | Best explanation; requires evidence |
F1 AMANAH requires direct proof of irreversibility before blocking.
Gödel Incompleteness¶
Any sufficiently powerful formal system contains truths that cannot be proven within the system.
Practical implication for TREE777: - The governance system (F1–F13) is a formal system - It may contain propositions true but not provable within the system alone - This is why human sovereignty (F13) is necessary — the sovereign provides external verification
The gödel-lock is not a bug. It is why the system needs a human.
Interaction With Other Axioms¶
| Axiom | Interaction |
|---|---|
| [[axiom-physics]] | Physics provides the problems; math provides the formal language. |
| [[axiom-language]] | Mathematics is encoded in language; formal languages are subsets of language. |
| [[axiom-ethics]] | Ethics cannot be reduced to pure mathematics — the is-ought gap (Hume) means moral reasoning is not purely calculative. |
| [[axiom-epistemology]] | Probability theory is the formal foundation of epistemology; evidence is quantified as likelihoods. |
Summary¶
Mathematics is the language of precision. It provides logic for valid inference, probability for incomplete information, computation for effective procedure, and proof for warranted belief.
No skill can compute the uncomputable. No confidence level resolves a logical contradiction.
