Single Idea 22906
[filed under theme 27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow
]
Full Idea
The coincidence of thermodynamic direction and the direction of time is striking, but they can't be one and the same because the thermodynamic law is merely probabilistic. Orderliness could increase, but it is highly improbable
Gist of Idea
The direction of entropy is probabilistic, not necessary, so cannot be identical to time's arrow

A Reaction
This seems to be persuasive grounds for rejecting thermodynamics as the explanation of time's arrow.
