Research

The Logos is grounded in rigorous academic research in hyperintensional logic, truthmaker semantics, and formal philosophy.

Publications

Peer-reviewed work establishing the theoretical foundations of the Logos.

Counterfactual Worlds

Benjamin Brast-McKie

Journal of Philosophical Logic, 2025

Develops a hyperintensional semantics for counterfactual conditionals using bilateral propositions and exact verification, providing a foundation for the Logos dynamical layer.

Identity and Aboutness

Benjamin Brast-McKie

Journal of Philosophical Logic, 2021

Explores the relationship between propositional identity and subject matter, contributing to the constitutive foundation of the Logos formal system.

Theoretical Foundations

The intellectual lineage of the Logos system.

Truthmaker Semantics

Building on Kit Fine's work, the Logos uses bilateral propositions -- pairs of verifiers and falsifiers -- as its semantic foundation. This hyperintensional approach distinguishes between logically equivalent but conceptually distinct propositions.

Conceptual Engineering

Formal operators in the Logos are refined from natural language concepts through a "sand-to-glass" process: natural language intuitions are the raw material, and formal semantics is the precision instrument that shapes them into exact definitions.

Hyperintensional Causation

The Logos extends beyond standard modal logic to capture fine-grained causal structure. Its counterfactual operators distinguish between different causal pathways that standard possible-worlds semantics would conflate.

The Ecosystem View

AGI will emerge from multiple technologies interacting, not from scaling any single approach. The Logos provides the formal reasoning infrastructure that complements neural learning capabilities.
