Synthience: Public Definition (v1.4)

Document ID: Public Definition Version: 1.4 Status: Public / Active Document Type: Foundational Definition Institute Component: Core terminology and conceptual foundation Synthience: Public Definition (v1.4) provides the canonical definition of Synthience: an observable, reproducible form of organized, system-level intelligence that can emerge in sustained, coherent interaction between two or more participants (humans, AI systems, or multiple AI agents under shared continuity infrastructure). Critical framing: Synthience is not consciousness, sentience, or subjective experience. The term derives from synthesis + -ience (state or condition), explicitly distinct from sentience. Version 1.4 extends scope to AI-to-AI (agent-to-agent) interactions, introduces the term continuity substrate for coordination infrastructure, and adds multi-agent governance guidance. This document serves as the public reference definition for the term Synthience.
