Reality Disjunction

Heisenberg takes a final step in his concluding chapter, on โ€œthe role of modern physics in the present development of human thinking.โ€ His use of the word โ€œdevelopmentโ€ (Entwicklung) signals a return to the fundamental dimension of reality that is โ€œHistoryโ€: that is, human mentality as historically unfolding. What Heisenberg now spotlights is the paradoxical recognition that the concepts of daily life or common sense are integrated into a much more comprehensive framework than modern scientific concepts. โ€œOne of the most important features of the development and the analysis of modern physicsโ€ is the โ€œexperienceโ€ that โ€œthe concepts of ordinary language, vaguely defined as they are, seem to be more stable, in the expansion of knowledgeโ€ than are โ€œthe precise terms of scientific language.โ€ On reflection, โ€œthis is in fact not surprising.โ€ For scientific language is to a much greater degree than ordinary language not only โ€œderives from an idealization,โ€ but, what is more, from an โ€œidealizationโ€ that is based on โ€œonly limited groups of phenomena.โ€ In sharp contrast, โ€œthe concepts of natural language [as Heisenberg now calls the language of common sense] are formed by the immediate connection with the world; the express reality,โ€ in its genuine wholenessโ€“even though, or precisely inasmuch as, the โ€œundergo changes in the course of the centuries, just as reality itself undergoes changes.โ€ As โ€œnatural language,โ€ however, โ€œthey never lose the immediate connection with reality.โ€ To be sure, the scientific concepts are โ€œidealiziationsโ€ with โ€œprecise definitionsโ€ that make possible the connection with a โ€œmathematical scheme;โ€ but โ€œthrough this process idealization,โ€ the โ€œimmediate tie with reality is lost.โ€ This is the price of scientific concepts must pay for their โ€œvery closeโ€ correspondence โ€œto reality in that part of reality which had been the object of research.โ€

Thatโ€™s all from โ€œOn Heisenbergโ€™s Key Statements Concerning Ontologyโ€ by Thomas L. Pangle.

In other words, Heisenberg believed something very similar to Nancy Cartwrightโ€™s philosophy in How the Laws of Physics Lie. Not only is her work one of the best philosophy books Iโ€™ve ever read, Cartwright is obviously correct in her main assertions. STEM absolutists would probably wail uncontrollably if they knew Werner Heisenberg essentially thought the same thing.
