All theories both affirm and negate themselves based on the perceiver. They have no value in and of themselves. Truth is the end of the perceiver (or to rephrase the realization of the absence of a perceiver). what we seek is its end which is possible only immediately in the Now and not at some point located in Time.
Time is continuation. Now is the end of the continuation at which point there is only Life, Truth, Awareness etc (whatever one might call it) leading to the cessation of all distinctions such as real and unreal, dream and awake states, transient and eternal etc.
It just is.
