Our mental apparatus is extremely handy, but not entirely logical and factual. Picasso himself, in a test, once authenticated an El Mir forgery of him, and also declared his own piece a forgery. Our memories slide along, a tiny bead of coordinates at the join of sliding short mid and long term layers, which themselves are altered at each recall. Stochastic processes and natural selection have built a fine machine, but it operates on schemas, heuristics, rules of thumb, vague impressions, stereotypic leaps (of all sorts, not just the big, consensus-named and -deplored one’s. Personal and describable only with deliberate attention). Also energy-saving; a CNS that was insistent on a closer fit to absolute accuracy would be a monstrous plague of inefficiency. If in fact we can establish absolutes all the way up into the human-linguistic realm.
We can all do well to recall that we function of necessity in a realm of shades and probabilities; fungible labels are never accurate labels (some are more helpful than others: the transpersonally portable essence of ‘table’ is not controversial in most cases; the transpersonally portable essence of ‘jew’, ‘racist’, ‘drug’, or ‘immoral’ just to name a few, can be monstrously fraught, and broad classes of persons with abstract labels might have no agreeable ‘essence’. Reform and ultraorthodox, may disagree who is a Jew. [disclaimer: I’m not Jewish]
As such, if, for the sake of argument, ‘Truth’ is an attribute used and understood by people and other consciousnesses, && ‘Reality’ is state of affairs objectively, by physics, (testable and tested or not; we speak of the whole universe here, not just a demarcated experiment), then Truth and Reality are not remotely the same object or function, the Venn chart overlapping only where and insofar as the truth-content of minds is also a wee section of the set of reality-phantasmagoria.

The map is not the territory. Universal concordance can rarely be true, and never possible. Multiple personal realities will persist eternally. No material construct (such as persons, computers, mathematics, or AIs) can contain a complete self-description (see, ‘the map is not the territory’).
