In both comp and the quantum, a case can be made that the irreversibility of memory (coming from usual thermodynamics, or big number law) can explain, through physical or comp-physical interactions, the first person feeling of irreversibility. But with comp we do start from a basic "irreversibility": 0 has a successor but no predecessors. And we do get physical symmetries (perhaps not enough: open problem), and then we get a temporal logic directly from the theaetetical definition of the first person (the knower). > Consider an infinite Hilbert space and a normed state vector on > it.
