Past experiencing was complete in itself while present experiencing is an interpretation of the past. This is the constant perspective of present experiencing for which the interpretation of experience means supplying in imagination the dimension that was missing from it at the time. Conversely, present imagines it is a natural and valid interpretation of the past, but future experience will show that to be untrue. The temporal chiasmus is not merely anticipation and recollection, but a complex existential game of validation and cancellation.
