Research and publications on the Vienna Circle and Logical Empiricism
are growing and flourishing for decades. On the occasion of the 35th
anniversary of the Institute Vienna Circle and 90 years after the
assassination of Moritz Schlick, the founder of the Vienna Circle, it
seems reasonable to critically assess and re-evaluate the scholarly
output on the history and influence of the Vienna Circle as a collective
as well as of its individual members. The aim of this conference is to
focus on added values and novelties in research and publications as well
as from the perspective of theoretical sustainability. A special
attention is laid on archival sources with new results and on completed
and running research projects dealing with Carnap, Gödel, Neurath, and
Schlick, in addition to gender and migration studies.
Sections:
1. The Vienna Circle and Logical Empiricism as collective phenomena
2. Individual members: From Gustav Bergmann to Edgar Zilsel
3. The Philosophical Periphery: Einstein, Popper, Ramsey, Russell,
Wittgenstein etc.
4. The European Context: Berlin, Cambridge, Helsinki, Prague, Paris, Warsaw
5. The “Americanization” and Diaspora: Reception and Influence
6. The Gender Dimension: Women in/of Logical Empiricism
7. The Vienna Circle / Logical Empiricism in contemporary history of
philosophy of science, scientific and analytic philosophy
8. Neglected research topics and future perspectives
Workshop 1: Exhibitions and movies on the Vienna Cricle and its members
Workshop 2: Completes, running and planned Edition Projects (Carnap,
Gödel, Schlick …)
Workshop 3: Archives and Primary Sources, VALEP

Title: /Possible Minds in Possible Bodies: Empirical and Conceptual
Considerations and Constraints/
_Abstract: _Could a brainless biological entity be conscious? Or a
non-biological entity with a brainlike processor? In this talk I’ll
outline the main conceptual, semantic, and computational methods we need
to state unambiguous hypotheses about mind/body possibilities and to
assess their truth in the light of up-to-date knowledge about actual
minds and bodies. I’ll also consider the implications of this
empirically-grounded approach for longstanding debates in philosophy of
mind between dualists and materialists, and reductive and non-reductive
physicalists.
Registration is free: If you would like to participate, please send an

Guten Tag,
im Namen von Arno Böhler informieren wir über folgende Veranstaltung am
Institut:
Herzliche Einladung zur Buchpräsentation
Euro-Transhumanism
von Stefan Lorenz Sorgner
19.03.2026 | 18:3020:00
Room 3D
NIG (Neues Institutsgebäude)
Universitätsstraße 7, 1010 Wien
Was wäre, wenn die Zukunft der Menschheit nicht von der Vision des Silicon
Valley bestimmt würde?
Am Rand ihrer Auflösung steht der europäische Humanismus vor tiefgreifenden
Herausforderungen: Künstliche Intelligenz, Biotechnologie und
posthumanistische Theorie verändern grundlegend, was es bedeutet, Mensch zu
sein. Die klassischen Ideale von Wahrheit, Güte und Schönheit einst der
moralische und ästhetische Kompass der europäischen Tradition geraten
dabei zunehmend in eine neue, verzerrte Form.
Dieses Buch führt die Leserinnen und Leser in den Euro-Transhumanismus ein
eine eigenständige, philosophisch fundierte Alternative zum
individualistischen und technokratischen Fokus des klassischen
Transhumanismus. Es knüpft an die kontinentaleuropäische Kulturtradition an,
lehnt Eurozentrismus, utopische Fantasien und dualistisches Denken ab und
untersucht pragmatische Wege, die Vielfalt menschlichen Gelingens zu
erweitern.
Es ist eine anregende Einladung, unsere Zukunft kritisch neu zu denken.
Dear all,
I hope you're having a nice start to the new semester.
I would like to draw your attention to a new series of reading groups
that I am now co-running together with Flaminia Pischedda (Department of
Linguistics) focused on Early Chinese texts. This semester we will read
the _Mencius _which is one of the foundational works of the Confucian
tradition and a key philosophical text of the Warring States period
(V-III century BCE). This text is famous for its optimistic view that
"human nature is good."
If you are interested in joining us, please send an email to me
(solmeng.hirschi(a)univie.ac.at) or flaminia.pischedda(a)univie.ac.at in
order to be added to the mailing list. You will then receive all
information and updates. We usually meet fortnightly during semester.
We will begin with Chapter 1. You can find a full translation here:
http://www.acmuller.net/con-dao/mencius.html [1]
The first session will take place on Thursday March 19, at 4-6 PM, at
Apostelgasse 23 in the 3rd district.
Many thanks, and I look forward to seeing you there!
All the best,
Solmeng

KiC Workshop on Semantic Indecision
5 March 2026
Room 3A, NIG, Universitätsstr 7, 3rd floor
10–11.15 Bryan Pickel, Glasgow: "Immanent Interpretation”
11.30–12.45 Emelia Stanley, Vienna: "Formalising Open Texture"
lunch
14.15–15.30 Richard Lawrence, Vienna: "Sharp definitions of concepts and the chaos of experience"
15.45–17.00 Max Kölbel, Vienna: “A Conservative Approach to Semantic Indeterminacy”
17.15–18.30 John MacFarlane, Berkeley: “Felicitous Underspecification"
Bryan Pickel, University of Glasgow (joint work with Derek Ball, University of St Andrews):
"Immanent Interpretation”
Abstract: Famous arguments purport to show that all, or a substantial fragment, of language is indeterminate in meaning. According to these arguments, if a speaker uses a sentence to express a proposition in a context, then an interpreter must (in principle at least) have more evidence favouring this proposition as the correct interpretation rather than rival interpretations. These arguments appeal to the claim that the interpreter or audience does not have sufficient evidence favouring one interpretation over its rivals. We show that these arguments fail because they ignore evidence that is available to interpreters – evidence that arises from the interpreters themselves as language users. But, our aim is not merely to rebut indeterminacy arguments. We construct a research strategy—immanent interpretation—for interpreters to meet the concerns of the proponents of indeterminacy arguments. We conclude by discussing important limitations on immanent interpretation.
Emelia Stanley, University of Vienna:
"Formalising Open Texture"
Abstract: Waismann’s (1947) notion of open texture captures a species of (non‐sorietal) semantic‐ and truth‐vagueness: that a concept can both apply and disapply to some given case, within a context of application. Noting that open texture resists characterisation in a classical framework, I present an original formalisation the notion. Using this model I then conjecture, contra Waismann, that open‐texture does not only occur in mathematics, but that it plays an indispensable role in characterising its epistemology, and particularly its resolution strategies for crises of non‐trivial disagreement.
Richard Lawrence, University of Vienna:
"Sharp definitions of concepts and the chaos of experience"
Abstract: Frege insists that, for logical purposes, concepts must be
sharply defined, and this assumption is now deeply embedded in our
contemporary approaches to semantics. Yet we have lost track of one of
the background assumptions of classical German philosophy which was part
of Frege's reason for that insistence: the idea that experience is
initially an unstructured chaos, on which we must impose structure by
actively seeking to grasp concepts in thought. I will argue that this
background played an important role in some of Frege's semantic ideas,
and that it is worth revisiting as we try to characterize phenomena like
vagueness.
Max Kölbel, University of Vienna:
“A Conservative Approach to Semantic Indeterminacy”
Abstract: So-called "felicitous underspecification" seems to be ubiquitous. Nevertheless communication succeeds effortlessly. A number of theorists (e.g. Viebahn, MacFarlane, King and others) have made proposals as to how semanticists should model this phenomenon. Some have proposed new-fangled semantic contents to do justice to the phenomenon. Others have offered pragmatic explanations of communicative success. In this talk, I want to draw attention to a third, more conservative approach that can at least in some cases be employed to explain what is going on.
John MacFarlane, University of California at Berkeley:
"Felicitous Underspecification”
Abstract: In recent work, Jeffrey King has called our attention to the problem of "felicitous underspecification": felicitous uses of context-sensitive language in the absence of determinate intentions about the needed contextual supplementation. An example would be talk of a "local shop" in the absence of a determinate intention about whether we mean local-to-the-city or local-to-the-county. After discussing the problems raised by this phenomenon, I consider King's own solution and argue that it is inadequate. I then describe the solution I think is needed, which makes use of the basic ideas of Allan Gibbard's plan expressivism. According to this approach, ordinary descriptive claims like "I went to a local bar" must be understood as expressive of practical plans for the use of words, as well as ordinary beliefs. Indeterminacy amounts to practical indecision.

Dear colleagues,
Benjamin Schnieder and I are organizing a summer school - please
forward to anyone who might be interested in participating:
The phlox research group is delighted to announce that the 2026
Hamburg/Vienna Summer School will be taught by Kit Fine (NYU). This
year’s topic will be *Decision Making under Parity*.
*Description*
How should we do decision theory without making the assumption that
preferences are linearly ordered? We shall first consider two standard
approaches to this question, one in terms of approximate value and the
other in terms of a range of precise values. We shall then develop our
own approach, which uses the notion of an approximate difference in
value between two items in place of the notion of the approximate
value of a single item. The course will cover a range of philosophical
and technical issues.
The event will take place from Monday, July 20th to Friday, July 24th
at the University of Vienna. For more information, please visit
https://hamburgersommerkurs.wordpress.com
*Call for attendance*
We very much welcome external participants to the Summer School,
though only a limited number of spaces are available. If you would
like to participate, please send a registration email, attaching (i) a
brief CV, and (ii) a short letter indicating how the course would
benefit your work, to
phlox-school (at) gmx (dot) de
Registration is open until April 30th; we will notify applicants by
the 10th of May.
Best wishes,
Yannic Kappes
