Three Definitions: Consciousness, Observer, Information.

This paper proposes minimal, non-recursive definitions for three fundamental concepts: consciousness is the capacity to perceive one’s own reflection; an observer is a consciousness capable of fixation; information is a state of affairs fixed by an observer. The definitions form a derivational chain resting on a single primitive (being) and are examined for internal consistency across multiple test scenarios. A structural distinction is drawn between the discrete subject and the gradient functions of consciousness. Comparison with major prior formulations — including Descartes, Nagel, Chalmers, Tononi, Shannon, Dretske, Floridi, Heidegger, and Wheeler — is provided. This work supersedes the earlier publication “A Minimal Observer-Dependent Definition of Information” (v2), incorporating and extending that definition within a unified framework.
