@starkatt As one of themthere stodgy Kantians, I believe that my brain necessarily perceives Time as A-series, whether or not I want it to (Also I keep not being able to travel back to past trauma to undo it so this belief literally keeps me sane). However, if the passage of Time is a necessary precondition on all my sensory experiences, B-series could very well be the case and I would still be stuck with my perceptions of A-series.
