We will now explore in more depth the problem with the conventional view of time.
From the linear perspective, time moves unambiguously forward in a positive direction with respect to the phenomenal world.
However on reflection much greater subtlety characterises the true position.
Once again it should be easy to accept that human experience is necessarily conditioned by external and internal polarities which operate in a dynamic complementary manner.
Thus inevitably, one's experience characterises a self (as subjective knower) in relation to a world (as objectively known) which are - relatively - internal and external with respect to each other.
Now when we attempt to separate these poles, the movement of time will appear to flow absolutely forward (in a solely positive manner).
Thus with respect to the world (as independent of self), time will appear to have an absolute forward positive direction; likewise in relation to the self (as independent of the world) time will likewise appear to have an absolute forward direction.
The position here is directly analogous with the road examples that I used so frequently in connection with the Riemann Hypothesis. So for example if one traveller fixes the direction of movement as "up" then movement along the road will take place in a positive direction (i.e. forward in both space and time). Likewise if a second traveller now fixes the direction of movement as "down" the road movement will again take place in a positive direction.
Thus when both reference frames i.e. "up" and "down" are separately fixed, movement for both travellers appears to take place in the same unambiguous positive direction where both move forward in space and time.
However when we now consider reference frames as interdependent i.e. in relation to each other, deep paradox results with both travellers now moving in an opposite direction from each other.
It is exactly similar in relation to the nature of time. When we try to view the self and the world as independent of each other, the movement of time appears in both cases as unambiguous moving in an absolute forward direction.
However if we now consider self and the world in dynamic relationship to each other, the movement of time is revealed as inherently paradoxical. Therefore from this relative perspective if the movement of time is positive i.e. forward with respect to the self, then it is thereby negative i.e. backward with respect to the world.
Likewise if the movement of time is positive with respect to the world, then it is thereby negative with respect to the self.
Thus when polar reference frames are viewed fully in a simultaneous manner, the movement of time is revealed likewise as fully paradoxical. Put another way from this perspective time has a merely present identity i.e. as a present moment that continually exists.
Therefore when placed against this background phenomenal movement in time is always of a merely relative nature. Therefore, if from one relative context, the movement of time is viewed as moving in a forward direction, this implies that from an equally valid alternative perspective its movement can be viewed as moving likewise in a negative direction.
Now the key reason why this is not immediately obvious to everyone is due to the very nature of the conventional scientific paradigm which operates through fixing reference frames in an absolute manner.
Thus the fundamental standpoint of Conventional Science is to attempt to view the objective physical world as if independent of the psychological self (and the corresponding mental constructs used to understand this world).
Once again though Quantum Mechanics (and indeed Relativity Theory) strictly undermine this standpoint, the fundamental paradigm of science has not changed.
And because both the internal and external poles are thus separated in this independent manner, they appear to directly correspond with each other in an absolute fashion. So underlying all conventional scientific investigation is a deep belief that the actual (internal) mental constructs that are used to investigate reality correspond directly with what is then externally revealed in an objective physical manner.
However once we allow for the necessary dynamic interaction as between these opposite poles, this comforting worldview breaks down with all physical investigation necessarily of a paradoxical relative nature.
And most crucially the very nature of time itself is now revealed as inherently paradoxical!
