Free will as temperature: Why AI agency is a useful abstraction
Statistically, free will explains behavior just like temperature explains gas—without exact omniscience.
A philosophical post compares free will to temperature, arguing that both are useful abstractions for systems too large and complicated to model in exact detail. Just as temperature helps predict the behavior of a gas when you don't know every atom's position, attributing free will to a person helps predict their actions when your knowledge of their internal state is fuzzy. The article notes that this idea resembles Daniel Dennett's "intentional stance" and Sean Carroll's "poetic naturalism," and adds a tongue-in-cheek analogy: just as two gas boxes prepared with identical initial conditions have the same temperature, two people prepared with identical initial conditions would have the same free will.
- Analogy maps statistical mechanics to agency: free will is an abstraction for complex, partially-observable systems
- Exact microstate knowledge makes free will epiphenomenal, but fuzzy knowledge makes it essential for prediction
- Directly parallels AI agent design—treating LLMs as intentional actors is a pragmatic modeling strategy
