Judgement and the Epistemic Foundation of Logic

Description

This compelling reevaluation of the relationship between logic and knowledge affirms the key role that the notion of judgement must play in such a review. The commentary repatriates the concept of judgement in the discussion, banished in recent times by the logical positivism of Wittgenstein, Hilbert and Schlick, and the Platonism of Bolzano. The volume commences with the insights of Swedish philosopher Per Martin-Löf, the father of constructive type theory, for whom logic is a demonstrative science in which judgement is a settled feature of the landscape. His paper opens the first of four sections that examine, in turn, historical philosophical assessments of judgement and reason; their place in early modern philosophy; the notion of judgement and logical theory in Wolff, Kant and Neo-Kantians like Windelband; their development in the Husserlian phenomenological paradigm; and the work of Bolzano, Russell and Frege. The papers, whose authors include Per Martin-Löf, Göran Sundholm, Michael Della Rocca and Robin Rollinger, represent a finely judged editorial selection highlighting work on philosophers exercised by the question of whether or not an epistemic notion of judgement has a role to play in logic. The volume will be of profound interest to students and academicians for its application of historical developments in philosophy to the solution of vexatious contemporary issues in the foundation of logic. ​ Front Matter....Pages i-xvii Front Matter....Pages 1-1 Verificationism Then and Now....Pages 3-14 Demonstrations Versus Proofs, Being an Afterword to Constructions, Proofs, and the Meaning of the Logical Constants ....Pages 15-22 Containment and Variation; Two Strands in the Development of Analyticity from Aristotle to Martin-Löf....Pages 23-35 Front Matter....Pages 37-37 Descartes’ Theory of Judgement: Warranted Assertions, the Key to Science....Pages 39-47 Striving, Oomph, and Intelligibility in Spinoza....Pages 49-65 Front Matter....Pages 67-67 The Role of Wolff’s Analysis of Judgements in Kant’s Inaugural Dissertation....Pages 69-83 Windelband on Beurteilung ....Pages 85-99 A Priori Knowledge in Bolzano, Conceptual Truths, and Judgements....Pages 101-130 Front Matter....Pages 131-131 Immanent and Real States of Affairs in Husserl’s Early Theory of Judgement: Reflections on Manuscripts from 1893/1894 and Their Background in the Logic of Brentano and Stumpf....Pages 133-150 Frege and Russell on Assertion....Pages 151-161
