On the 'transcendent' view of meaning, theorising is making meanings of meanings outside semiotic systems. On the 'immanent' view of meaning, theorising is making meanings of meanings inside semiotic systems, such as the meanings made by language of the meanings of perceptual systems. The findings of quantum physics — 'a phenomenon is not a real phenomenon until it is an observed phenomenon' — are consistent with the 'immanent' view, but not with the 'transcendent' view.
