We motivate and develop a perspectival A-theory of time (future/present/past) and probe its implied interpretation of quantum mechanics. It will emerge that, as a first take, the time of relativity is a B-series (earlier-times to later-times) and the time of quantum mechanics is an A-series. There is philosophical motivation for the idea that mutual quantum measurement happens when and only when the systems’ A-series become one mutual A-series, as in the way qualia work in the Inverted Spectrum. This seems to (...) account for certain quantum phenomena, including that the electrons of a Bell pair do not have definite spins until measurement, as ‘until’ here is a (perspectival) A-series notion. Various issues in the foundations of quantum mechanics are canvassed. (shrink)

There is little doubt that we perceive the world as tensed—that is, as consisting of a past, present and future each with a different ontological status—and transient—that is, as involving a passage of time. We also have the ability to execute precisely timed behaviors that appear to depend upon making correct temporal judgments about which changes are truly present and which are not. A common claim made by scientists and philosophers is that our experiences of entities enduring through transient changes (...) are illusory and that our apparently accurately timed behaviors do not reflect dynamical time. We argue that our experiences of objects enduring through transient changes need not be thought of as illusory even if time is not dynamic at the fundamental level of reality. For, the dynamic properties we experience objects as having need not be fundamental properties. They could be weakly emergent from static, temporal properties. Temporal properties, on this view, are similar to ordinary properties like that of being solid, which are correctly experienced as properties of medium-sized material bodies even though they are not instantiated at the fundamental level of reality.
