I accept that McTaggart's A-series and B-series are not inter-reducible and that both are needed for a complete temporal description of a physical system. I consider the Wigner's Friend thought experiment. The A-series are associated with each (quantum) system, and relativity is associated with the B-series. I consider temporal evolution through this 'hybrid' time. We may define the rate of temporal flow as 1 B-series second per A-series second.

Some not quite random thoughts on the logic of qualia.

We indicate how to construct a logic of qualia.

On being released from her black-and-white room into a colorful world it would seem Mary learns something new (the Knowledge Argument). On being released from his B-theory room into an A-theory world it would seem Mark learns something new (the Temporal Knowledge Argument). These thought experiments are parallel to each other and can inform each other.

The logic of qualia is different than classical logic. We take the first steps in defining it and applying it to the Hard Problem.
