SUMMARY:CEFISES Seminar: Peter Verdee\, "Multiperspectival supervaluationism and deep indeterminacy"
DESCRIPTION:Livestream  https://youtu.be/XqZpCG0h7tE \nSeries: OLOFOS \nSpeaker: Peter Verdee (UCLouvain) \nTitle: « Multiperspectival supervaluationism and deep indeterminacy » \nAbstract  \nIn this talk\, we present a novel approach to addressing indeterminacy\, inspired by supervaluationism. Our investigation begins with Bradford Skow’s argument (cf. [1]) for the conceivability of deep metaphysical indeterminacy\, grounded in the Kochen-Specker theorem from quantum mechanics. The central idea is that\, unlike cases of shallow indeterminacy\, where a supervaluationist framework diagnoses indeterminacy as the impossibility to select among multiple consistent assignments of truth values to propositions (cf. [2])\, deep indeterminacy involves situations in which no such consistent assignment is possible. \nTo model such cases\, we propose a formal framework based on truthmaker semantics. This model partitions language into distinct fragments\, each representing a consistent way of specifying reality. States are conceived as potentially incomplete and/or inconsistent containers of information\, serving as verifiers or falsifiers of sentences. We introduce a binary relation of admissible extension between states\, which enables the definition of superverification and superfalsification—truth or falsity across all admissible extensions. \nWe will present the formal model\, demonstrate its compatibility with quantum logic\, and explore its broader applicability beyond quantum indeterminacy. In particular\, we suggest that this framework may illuminate reasoning in contexts where open problems in science or mathematics are best understood through multiple precise yet mutually incompatible perspectives each offering insight\, but not integrable into a single global language. \nReferences\n[1] Skow\, B.

SUMMARY:CEFISES Seminar: Sami Pihlström\, "Putnamian Transcendental Arguments"
DESCRIPTION:Livestream recording  https://youtu.be/LbseG3XKKDo \nSeries: MEPHISTO (MEtaphysics and PHIlosophy of Science: Transcendental Orientations) \nSpeaker: Sami Pihlström (University of Helsinki) \nTitle: « Putnamian Transcendental Arguments » \nAbstract \nGiven Hilary Putnam’s deep interest in the critical philosophy of Immanuel Kant\, it is surprising that he never sympathized with his interlocutors’ proposals to compare his views on realism and idealism to Kant’s transcendental idealism. In this paper\, I am trying to interpret Putnam as a Kant-inspired transcendental philosopher. I will confine myself to an investigation of a selection of Putnam’s (or\, rather\, Putnamian) transcendental arguments. I will argue that some of these arguments offer us useful philosophical resources for developing a pragmatic non-reductive naturalism – i.e.\, a version of transcendental naturalism\, or pragmatically naturalized transcendental philosophy. The paper will briefly discuss five transcendental arguments: (i) the Brains in a Vat argument; (ii) the argument against metaphysical realism based on conceptual relativity; (iii) the argument for realism rejecting relativism and other non-realisms; (iv) the argument against reductive naturalism (or physicalism); and (v) the argument for the entanglement of fact and value. \n
