This is something of a companion piece to The Thing in Itself in the Light of a Mirror piece which set the intellectual world alight recently.
As I stand in a certain spot looking in a certain direction, I do not occupy a definitive point of perception which excludes the reality of all other possible points of perception. Instead I occupy a continuously shifting position within the visual field, which is comprised of an infinity of points of perception all existing simultaneously. Reality here is the totality of this field of vision as opposed to the distinct reality of the individual points.
The same can be said of time. We occupy a continuously shifting position within this field, again with all the individual points of time existing simultaneously. This may sound stranger than the field of vision, but to take a look at the alternative which is that the only point of reality in time is the present moment which is continuously advancing thus sending all previous time into oblivion or unreality. Time from this perspective is a knife-edge of reality surrounded by unreality in both directions, which seems a very artificial picture of the real.
