[catalogued under 27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow]

Full Idea

It would seem arbitrary to say that the direction of time is reversed if the whole universe becomes more orderly, but it isn't reversed for any particular sub-system that becomes more orderly.

Gist of Idea

It is arbitrary to reverse time in a more orderly universe, but not in a sub-system of it

A Reaction

The thought is that if time's arrow depends on entropy, then the arrow must reverse if entropy were to reverse (however unlikely).
