Heisenberg takes a final step in his concluding chapter, on โthe role of modern physics in the present development of human thinking.โ His use of the word โdevelopmentโ (Entwicklung) signals a return to the fundamental dimension of reality that is โHistoryโ: 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. โOne of the most important features of the development and the analysis of modern physicsโ is the โexperienceโ that โthe concepts of ordinary language, vaguely defined as they are, seem to be more stable, in the expansion of knowledgeโ than are โthe precise terms of scientific language.โ On reflection, โthis is in fact not surprising.โ For scientific language is to a much greater degree than ordinary language not only โderives from an idealization,โ but, what is more, from an โidealizationโ that is based on โonly limited groups of phenomena.โ In sharp contrast, โthe 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 wholenessโeven though, or precisely inasmuch as, the โundergo changes in the course of the centuries, just as reality itself undergoes changes.โ As โnatural language,โ however, โthey never lose the immediate connection with reality.โ To be sure, the scientific concepts are โidealiziationsโ with โprecise definitionsโ that make possible the connection with a โmathematical scheme;โ but โthrough this process idealization,โ the โimmediate tie with reality is lost.โ This is the price of scientific concepts must pay for their โvery closeโ correspondence โto reality in that part of reality which had been the object of research.โ
Thatโs all from โOn Heisenbergโs Key Statements Concerning Ontologyโ by Thomas L. Pangle.
In other words, Heisenberg believed something very similar to Nancy Cartwrightโs philosophy in How the Laws of Physics Lie. Not only is her work one of the best philosophy books Iโve 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.
