I am happy to announce the seventh session of our History of Logic seminar series. The session will be held on Wednesday, April 23, from 3:00 p.m. to 5:00 p.m. Central European Summer Time (CEST).
It will be held online, via Zoom. The Zoom link can be obtaining by contacting us at the address displayed on the Contacts page of the Seminar's website.
On this occasion, we will host a talk by Göran Sundholm, Professor of Philosophy of Mathematics and Logic at the Institute for Philosophy of the University of Leiden. His areas of research are the Philosophy of Logic, with a focus on Martin-Löf's Constructive Type Theory, and the modern History of Logic, with a focus on Bolzano, Frege, Wittgenstein, as well as on the Metalogical Turn.
His talk is titled Wittgenstein's Tractatus as Point of Intersection between two Historical Lines of Development. Here is a short abstract:
The History of Logic knows two traditions with respect to validity, the Containment account, according to which an inference is valid when its conclusion is somehow "contained" in the premisses, and the Variational account, according to which an inference is valid if its associated implication is truth-preserving "under all variations" of non logical terms. My paper Containment and Variation; Two Strands in Development of Analyticity from Aristotle to Quine in: M.S. van der Schaar(ed.), Judgement and the Epistemic Foundation of Logic, Springer, Dordrecht, 2013, presents this dichotomy of traditions in a general way and a manuscript version can be found at: https://www.researchgate.net/publication/300092519_Containment_and_Variation_Two_Strands_in_the_Development_of_Analyticity_from_Aristotle_to_Martin-Lof. My zoom talk for the Naples History of Logic seminar will apply this general framework specifically to Wittgenstein's Tractatus and consider it as the point of intersection between these two traditions.
