Meaning's Recursive Ascent: From Entropy to Civilization

This framework proposes a stratified ontology of meaning grounded in thermodynamics and elaborated through successive evolutionary transitions. Drawing on physicist Carlo Rovelli's distinction between 'direct' and 'indirect' meaning, it argues that the most primitive semantic register is simply information with immediate causal bearing on an organism's capacity to resist Entropic dissolution — a survival signal. Biological evolution then builds upon this foundation, generating goal-directed behavior, homeostatic regulation, and reproductive strategy as increasingly complex expressions of the same underlying imperative. The Emergence of nervous systems introduces a qualitatively new register: felt experience, Normative valence, and phenomenal subjectivity — dimensions of meaning that are causally dependent on thermodynamic Viability but cannot be derived from it by any straightforward reduction. Language marks a second major discontinuity. It does not merely encode meanings from prior levels but actively reframes them while simultaneously generating domains — self-awareness, theory of mind, metaphysics, science — with no functional analogue below the cultural threshold. Indirect meanings, those relevant not because they directly sustain survival but because they increase the probability of acquiring directly meaningful information, prove recursively generative: each layer of abstraction can bootstrap further layers, producing the extraordinary semantic complexity of human civilization. The philosophical payoff is a position that avoids both eliminative reductionism and mysterianism. The relationship between levels is one of foundation rather than identity: higher-order meanings are genuinely novel and irreducible, yet they remain tethered to the Thermodynamic substrate through an unbroken causal chain. The book-and-paper analogy captures this precisely — the contents of a text cannot be reduced to its physical medium, yet the medium remains an indispensable condition of possibility.
