The LogicLounge as a modern philosophical symposium

Meeting place for friends of logic • Insights in exactly one hour live and in public • Tribute to antique philosophical symposium

The LogicLounge is a meeting place for friends of logic from science and the public. Created during the Vienna Summer of Logic 2014, the largest conference in the history of logic research, LogicLounge features discussions on the “science of reasoning” in the areas of logic, philosophy, mathematics, computer science and artificial intelligence.

Its seven successful instances during the conference (see here) inspired the LogicLounge initiators, Helmut Veith (TU Wien) and Oliver Lehmann (IST Austria), to continue the one-hour discussions with eminent scientists – offering insights into the millennium old discipline of logic, celebrating the antique concept of the philosophical symposium (from Greek συμπίνειν sympinein, “to drink together”).

06/06/2023 in Vienna

Carla P. Gomes and Bart Selman (Cornell University, Ithaca, NY): Exploring Connections: Wittgenstein, Gödel, and ChatGPT
moderated by radio journalist Sarah Kriesche (Ö1/ORF)

Carla Gomes and Bart Selman are pioneers in the field of computational sustainability. At LogicLounge 2023 held in Vienna, they discussed the notion of truth in large language models with the audience. Since its launch by OpenAI in autumn 2022, ChatGPT has become the hot topic in computer science, and due to constant improvements, its abilities are a source of fascination as well as skepticism. It can write a job application, give legal advice, and pass graduation exams. So what is it – a chatbot, a language model, or even an artificial intelligence? A fact is that it cannot (yet) tell right from wrong, make generalizations, or make inferences like human beings do hundreds of times every single day. What would Wittgenstein have to say about the truth value of ChatGPT’s propositions? What are its potentials and limitations, and how will it affect our lives in the future? So much food for thought at this year’s LogicLounge!

Stuart J. Russell (University of California, Berkeley): AI and the problem of control
moderated by radio journalist Sarah Kriesche

Stuart J. Russell is a British computer scientist known for his contributions to artificial intelligence (AI). At the LogicLounge 2022 held in Vienna, he talked about the need to impose limits in the area of artificial intelligence and algorithms. While he considers himself to be an optimist, Russell takes a critical view of the use of AI. During the discussion, it quickly became clear that AI and algorithms already play a major role in numerous areas of our lives, e.g., in advertisements that are presented to us online, in the assessment of a person’s creditworthiness, or in self-driving cars. As AI increasingly intervenes in our lives, this intervention must also be regulated, which is already happening to some extent. For example, a person’s ethnic origin must not have any influence on their creditworthiness, and in the case of some chatbots, it must be recognizable to viewers that they are dealing with an AI and not with an actual human being – especially when commercial products are offered.

This LogicLounge was co-located with IJCAI 2022 and hosted by VCLA and CAIML.


22/07/2021, VIRTUAL

Joscha BachCognitive AI: From AI models to mental representations?

The aspiration of philosophy can be understood as the integration of all theories, and the aspiration of mathematics as the exploration of all consistent languages. Philosophy starts out with natural languages, mathematics with formal ones. Just as it is hard to say provably true things in the languages of philosophers, it is hard to make meaningful statements about our world using the languages of mathematicians. Grounding philosophy in mathematical languages requires the mathematization of the mind. In this sense, Artificial Intelligence is more than research into advances in information processing. It is also a daring, risky and extremely important philosophical project.
