Because of the experimentally demonstrable fact that the minimum complex of acts involved in measuring always alter that which is being measured, we accept Heisenberg’s principle of inherent indeterminism which concedes that absolute exactitude is unattainable. It is also experimentally demonstrable that the relative degree of inexactitude of measurement to be tolerated at any one moment is progressively reducible.
“In view of the foregoing (a) indeterminism, and (b) reducible tolerance, and subject to further modifying inclusions, exclusions, rearrangements, and refinements, we may assume that all definitions are tentative.”
