Semantic Information as Physical Reality: Meaning Without a Mind to Impose It
The deer already knows what matters.
Shannon's theory measures whether information arrives intact, but says nothing about whether it matters. A new framework grounded in far-from-equilibrium thermodynamics shows that meaning arises naturally when an entity's survival depends on the information it holds about itself and its world.

Shannon information theory provides a powerful framework for quantifying the fidelity of signal transmission, but it is deliberately agnostic about meaning. A perfectly transmitted string of random digits carries maximal Shannon Information while conveying zero semantic content. This deliberate omission — the exclusion of "aboutness" — has been enormously productive for engineering but has generated persistent confusion whenever information theory is imported into biology, cognitive science, or philosophy of mind.
The critical advance comes from work by Artemy Kolchinsky, David Wolpert, and others operating at the intersection of complexity science and nonequilibrium thermodynamics. Their framework identifies semantic information as information that an individuated entity — one that maintains informational boundaries distinguishing it from its environment — possesses about itself and its surroundings insofar as that information bears on the entity's continued Viability. Meaning, in this account, is not observer-dependent attribution but an intrinsic feature of the structural coupling between an entity and its context. The deer processing the lightening sky at dawn exemplifies this: the causal relevance of that signal to the deer's survival constitutes its semantic content.
This reframing accomplishes something philosophically significant. It grounds meaning in physics — specifically in the thermodynamic requirements of far-from-equilibrium self-maintenance — without collapsing it into mere mechanism. It also provides a principled way to trace how semantic complexity scales from minimal Dissipative Structures through biological organisms to the elaborate meaning-making of human culture, offering a continuous naturalistic account where previously there was only a gap between syntax and semantics.
