Quantum theory (QT) treats of “observables” yet the term “observer” remains hardly a rigorous notion. We argue that the uncertainty principle of QT can be understood in the Gödel sense that: any given observer constitutes own practical definition of “the unobservable” (if superposition) namely length scale, phase space, non-local action, fundamental frequency etc. Conversely, the observable is definable strictly only in inverse-observer terms as, that is, the “collapse” namely inverse-length, phase-points, locality, harmonics respectively. Granted this picture is not a-priori intuitive we show that it resolves key modern difficulties plus it has formal grounds. One pictures the observer thus in the manner of Gödel’s “consistency-is-undecidable” or Planck’s “the-constant-is-uncertainty” or indeed Einstein’s “speed-of-light-is-null-information” etc. definitive of which three cases, we assert, is Peano’s (and Noether’s?) notion of the constant as being for any gamut of variables/symmetry the meta-state (“conserved current”?). Given then that the observer is in any scheme of events the invariance (constant) it should be the case that it is the observer proper and not his observables which should constitute the violation of Bell’s inequality—if as the infinitesimal/imaginary axis or as the dimensionless/infinite-dimensional or the so-called conservation law etc. We posit: the observer is by definition the virtual exchange (field) of standard model or “space-time” of GR or just the “metric”—defined by the singular trait that it is the de facto universal constant i.e. the natural unit and hence natural limit of physical information. As a prediction we show herein an exact value to define man (perhaps our purest sample of observer) as also the natural unit for quantum gravity. Ultimately, that known hitherto as the potential (conservation law) becomes here same exactly as the “mind” or the “life” i.e. strictly put: “the-observer-as-the-unobservable” (superposition).The observer is for us per se the “entity”—in the sense of “phase-space” (normal mode; fundamental; wave speed) giving us an intuitive picture of observables that is same in fact as Huygens’ wave fronts/wavelets (or Everett’s many-worlds, or indeed Darwin’s evolution/speciation of “life”) same in short as any “spontaneous symmetry breaking”.
