The principles of neopositivism and the laws of thermodynamics

Didier Lairez

The second law of thermodynamics follows directly from neopositivist principles via a definition of information as non-redundant truth from observation.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

from the definition of information as a truth that can only come from an observation but cannot be redundant, we obtain Clausius' inequality.

C2weakest assumption

That the chosen definition of information is a direct and complete expression of neopositivist principles and that no additional physical or mathematical assumptions are required to reach the thermodynamic inequality.

C3one line summary

The second law of thermodynamics is derived from neopositivist principles using a definition of information as non-redundant truth obtained only from observation.
