Explanations from contemporary quantum theories: some ontological   characteristics
  We begin by surveying the historical positions in different attempts to understand the material world since the rise of modern science, with specific focus on the role of Cartesian primary qualities in explanatory conceptualisation. Moreover the opening chapter argues that although explanatory narratives are essentially epistemological constructions, they require a general metaphysical backing through the explainer's and explainee's commitments to take the concepts and higher structures composed of them as directly referential. Two methodological perspectives on theory construction, Einstein's division into principle and constructive theories, are then delineated along the lines of their metaphysical and explanatory potential, and presented as the research instrument with which to approach the specific-case-study instances of quantum theory reconstruction. A specific strategy of arguing for scientific realism ('the simple transcendental strategy') is then presented and connected to the challenges that the phenomena (EPR correlations and 'teleportation') from the domain of contemporary quantum theory pose for it. The opening chapter concludes with a survey of the general models of explanation and their position with respect to the principle-constructive dichotomy introduced above. Finally, an explanatory model containing extended material-like entities along with further primitives, universal laws of temporal evolution, is argued for. Consequently, in the interest of a wholesome realistic response to the sceptical challenge about the explanatory aims of science, we recommend that even the common sense conceptual framework replaces the extended material structure with 'generalised things' as re-identifiable invariants through change as the fundamental unit of the realist ontology.
