LINGENIC

A notation for knowledge representation.

Mathematics for structure. Natural language for content. Any human language.


THE COMPOSITION

Some things could not be expressed before. Not in natural language. Not in formal logic. The notation for them did not exist.

Natural language carries meaning but lacks structure. Formal logic has structure but loses meaning. The gap was absolute. You chose one or the other. You lost something either way.

Lingenic closes the gap. Not by compromise. By composition.

    P(тоска) = 0.0 ∧ ¬∃object(тоска) ∧ present(тоска)

The structure is rigorous — probability, existential negation, conjunction. The content is native — тоска is тоска, not a translation. Neither is reduced. Both are present.

The space of what can be expressed has expanded. Concepts that could only be gestured at — or formalized into unrecognizability — can now be written with precision and preserved intact.

This is the point.


THE IDEA

Every human language expresses the same meanings differently. Lingenic is what remains invariant — the structure that persists when surface is stripped away.

Logical connectives, quantifiers, modality, probability, causation, types — expressed in established mathematical notation. The content — the actual things being talked about — remains in natural language, unmodified.

The result: ∀x(human(x) → mortal(x)) and ∀x(人間(x) → 死ぬ(x)) are structurally identical.


THE COMPONENTS

Lingenic invents nothing. It composes known primitives.

Propositional and predicate logic. Modal, temporal, epistemic, deontic logic. Probability theory. Counterfactual and interventionist causation. Lambda calculus. Type theory. Dynamic logic. Set theory. Relational algebra.

Each developed separately over 150 years. Never combined until now.


THE READER

AI models are the first readers that natively consume mathematical logic, type theory, lambda calculus, probability, and natural language simultaneously.

The barrier for humans is high — years of training across multiple disciplines.

The barrier for AI is zero. It reads Lingenic natively. It writes Lingenic natively.

AI is the first-class citizen.


THE SPECIFICATION

https://lingenic.ai/ai/language/Lingenic/LINGENIC-SPECIFICATION.lingenic

Written in Lingenic. Self-describing. The notation explains itself using itself.
