Call for Abstracts for Wittgenstein Workshop

2025-07-30T13:49:00.006-03:00

Workshop “Wittgenstein on Epistemic Practice: Ignorance, Hinges and Skepticism.”

Dates: March 9-10, 2026.

Location: Hanse-Wissenschaftskolleg Institute for Advanced Study, Delmenhorst, Germany.

Organizers: Hans-Johann Glock (University of Zurich), Tammo Lossau, (University of Bremen), Mark Siebel (University of Oldenburg), and Norman Sieroka (University of Bremen).

Keynote Speakers: Hans-Johann Glock (University of Zurich) and Michael Williams (Johns Hopkins University).

Aside from an interest in linguistic practice, Wittgenstein also (primarily in On Certainty) shows an interest in our epistemic practice. His idea that our practice of doubting requires us to rely on “hinges” has gained significant prominence in recent discussions, but many of his other observations on skepticism and the idea of ignorance also allow for a range of interesting applications. Based on a close and attentive reading of Wittgenstein’s works, this workshop aims to make progress on understanding our epistemic practice and the issues surrounding it.

Presentations can be on any topic connected to Wittgenstein’s late epistemology and could include exegetical questions as well as topics from hinge epistemology or applications of Wittgenstein’s ideas to issues like conspiracy theories, echo chambers or the epistemology of democratic processes.

This is a call for the submission of short abstracts (ca. 500-800 words) of those interested in presenting a talk at the workshop. These abstracts should be anonymized for review, but authors should disclose their name and affiliation in the e-mail. Presentations should be ca. 30 minutes long, as each slot will be 60 min. in total. Abstracts should be sent to lossau1@uni-bremen.de by October 1, 2025. Organizers aim to notify accepted speakers by November 1, 2025. They are currently trying to acquire funding that will provide (limited) support for travel costs, but cannot guarantee such support at this point.

Summer School "The Problem of Skepticism"

2025-05-28T18:19:00.001-03:00

Both Kantian and post-Kantian Idealism emerged out of an engagement with problems of skepticism. Kant was famously led to develop his critical philosophy after being awoken from his ‘dogmatic slumbers’ by Hume’s empiricist skepticism, whilst his practical philosophy continually wrestles with the problem of how to respond to skeptical demands to prove the validity of the moral law – and of whether we need to. His idealist successors then worried that Kant’s own philosophy itself entailed skeptical consequences: a restriction of cognition to appearances, the relegation of metaphysical truths to the realm of faith and a banishment of moral worth from the realm of the knowable. These problems, they thought, were symptomatic of Kant’s remaining within a framework shaped by the problematic of modern skepticism. To be a true science, they thought, philosophy had to confront and overcome the radical challenge of ancient skepticism. Assessments of their success or failure in doing so went on to determine the course of German philosophy.

This year’s summer school engages with this complex of issues, which will be explored through a series of workshops and keynote lectures. The summer school will be led by Markus Gabriel and Michael Forster, with keynote speakers including Karl Schafer (UT Austin), Jessica Berry (Georgia State), Dietmar Heidemann (Luxembourg), Nick Stang (Toronto), and others.

Date: August 11-22, 2025

Location: International Centre for Philosophy NRW, Poppelsdorfer Allee 28, 53115 Bonn.

If you wish to attend, please submit an application consisting of a CV (max 2 pages) and a statement of interest (max 1 page) combined in one document to Alex Englander (alexeng@uni-bonn.de) by June 10th.

For students who require financial assistance to cover travel and accommodation expenses, there will be a small number of stipends available. If you require a stipend, please indicate this in your statement of interest.

Popkin and Skepticism

2024-12-17T09:45:00.001-03:00

The following book on Richard Popkin has just been released:

Jeremy Popkin, Asher Salah, and Giuseppe Veltri (eds.), A Sceptical Jew. Richard H. Popkin’s Private Republic of Letters. Maimonides Library for Philosophy and Religion, Volume: 8. Brill, 2025.

Richard H. Popkin (1923–2005) was a pioneer in the field of Jewish studies. His numerous books and articles broke new ground in the study of Jewish-Christian relations in the early modern period and in the exploration of the impact of Jews and Judaism on philosophy and religious thought. A Sceptical Jew: Richard H. Popkin’s Private Republic of Letters brings together selections from Popkin’s private correspondence and other documents to illuminate the sources of his interests and the nature of his contributions to the fields in which he worked.

Skepticism in the 16th Century

2024-12-12T15:32:00.001-03:00

There's a new book by Emmanuel Naya (École Normale Supérieure de Lyon):

Lire le scepticisme au xvie siècle: Le phénomène pyrrhonien. Paris: Classiques Garnier, 2024.

“How did skeptical thinking emerge during the Renaissance? This cannot be understood in the light of modern studies on such an ancient current. Scholars of the sixteenth century were readers dependent on the interpretation of printer-booksellers, whose key role is studied here.”

For more information, click here.

Error Theory and Fictionalism

2024-12-06T21:21:00.003-03:00

This is a topic on which he has published extensively, and so I'm curious to see what new insights he has to offer in this work. For further information, visit here.

The session will consist of two 55-minute slots (no commentators) in which researchers can present their latest work on any topic pertaining to skepticism (very broadly construed). All presenters must register for the APA conference. Remote presentation or participation will not be possible.

Please submit your paper (preferred) or extended abstract (allowable) to James Beebe at jbeebe2@buffalo.edu by July 5, 2024.

Please do not submit a paper or abstract if you will not commit to participating, should your submission be accepted.
