From What Is the Case to the Limits of Case Formation

This publication develops a methodological argument connecting two earlier monographs by the author, Was der Fall sein kann and Fallbildung, with conceptual pressures arising from Wittgenstein’s Tractatus Logico-Philosophicus and Heidegger’s Being and Time. The paper introduces regressive minimalization as a method for moving from philosophically strong terminal categories toward weaker conditions that must already obtain before those categories can be warrantedly applied. On the Wittgensteinian side, the argument moves from determinate facticity toward determinability and non-indifference; on the Heideggerian side, it moves from the full existential qualification of Dasein toward weaker forms of differentiating responsiveness and case formation. The publication further develops the idea of conceptual continuation without attribution: philosophical engagement with a canonical text may legitimately begin from a formulation in that text without attributing the resulting theory to the original author. A final extension concerns the limits of case formation. The argument distinguishes between what is the case, what can become a case for a distinguishing instance, and what is articulable for us. It argues that failure of articulability or case formation does not by itself justify an inference to non-being. At this outer boundary, regressive minimalization becomes a discipline of non-negation: the limits of conceptual articulation must not silently become the limits of what can be. The paper does not propose an alternative ontology beyond Wittgenstein’s facts, nor does it reinterpret Heidegger’s Dasein as a case-forming mechanism. Rather, Wittgenstein and Heidegger function as demanding conceptual test cases for a methodological investigation into difference, articulation, case formation, and the limits of warranted ontological negation. Generative AI was used during the development, drafting, revision, linguistic editing, structural organization, source-oriented checking, and critical review of the paper. The author determined and evaluated the argument, source selection, and interpretations and assumes full responsibility for the final text.
