Logical Aliveness: Minimum Criteria for History-Informed Observer Systems

Abstract
Logical Aliveness: Minimum Criteria for History-Informed Observer Systems proposes a substrate-agnostic threshold condition for identifying when a system becomes observer-like in a logically meaningful sense. The paper introduces logical aliveness to distinguish systems that are merely life-like from systems capable of history-informed future-state navigation. Many systems exhibit structure, persistence, regulation, cycles, environmental coupling, or self-organization. These properties may make a system appear life-like, but they are insufficient to establish logical aliveness. A logically alive system must preserve distinguishable states across time, update itself through feedback-sensitive memory, evaluate possible futures using encoded history, and bias action toward accessible future states. The technical note defines six minimum criteria: Discrete distinguishable states Stable encoding across time Rule-governed state transitions Feedback-sensitive memory History-informed future evaluation Action bias toward accessible futures The paper further clarifies perception in observer-relative and substrate-neutral terms, allowing the definition to be applied to biological, synthetic, organizational, institutional, computational, and symbolic systems without reducing perception to biological sensation. Logical aliveness is not presented as equivalent to consciousness, biological life, sentience, subjective experience, moral personhood, legal personhood, or agency in the full philosophical sense. Rather, it is proposed as a conservative minimum observer-system condition: the point at which a system begins to use remembered state-history to alter how it navigates future-state space. Boundary cases examined include crystals, thermostats, hurricanes, reaction-diffusion systems, slime mold, chess engines, persistent-memory LLM agents, legal institutions, and biological organisms. These examples are used to clarify the distinction between life-like mirror-forms and systems that may satisfy the threshold for logical aliveness. This work provides a foundational layer for later development in Accessibility Geometry, Multi-Scale Observer Dynamics, substrate-agnostic life theory, cybernetics, synthetic observer systems, and institutional analysis.
