I don't think it's necessary to introduce human perception to illustrate the directionality of time.

Mathematically, there are innumerable physical laws where time is a variable, where the current state of something is dependent upon the previous state - and specifically _independent_ of the future state.

...or maybe that too is just an illusion. Perhaps we misinterpret those equations (eg simple Dynamics in Physics I).

...but regardless, discussing human perception is an unnecessary complication in the discussion.
