Objectivity/knowledge/Maturana: knowledge, first personally, privately - that allegedly transferable is only created by the listener (observer).
Definition objectivity in parentheses/Maturana: should mean: everything that happens is, brought forth by the observer in his life praxis as the primary basis of experience and any explanation for this is secondary.
There are then as many areas of existence as there are kinds of distinction - leads to the multiverse - all verses are equally legitimate, although they are not all as pleasant - objectivity without parentheses/MaturanaVs: demands unit and ultimately leads to reductionism - because it must define reality as a single, last valid area (independent existence).
E.g. explanation by action, not by independent reality.
Objectivity without parentheses/Maturana: does not distinguish between illusion and perception, because it asuumes an independent reality - that contradicts the structural determinism of living systems - cannot explain scientific explanations because observers ability is presupposed.
