MAXWELL'S DEMON AS A THERMODYNAMICALLY UNSTABLE OBSERVER

This paper resolves the Maxwell’s Demon paradox by treating the Demon as a real physical system embedded in a thermal environment rather than as an abstract decision-maker. Using a strict physics-only, non-mathematical, logical-necessity framework, it shows that any system capable of discrimination must be physically coupled to what it observes, exposed to thermal noise, and continuously stabilized against fluctuations. That stabilization requires ongoing dissipation, making the Demon thermodynamically unstable and preventing any net entropy reduction. The paradox dissolves once discrimination is recognized as a physically enforced process subject to the same thermodynamic constraints as all matter.
