Marta Sznajder

Marta Sznajder is a philosopher and historian of 20th-century inductive logic, currently serving as a Marie Skłodowska-Curie Fellow at the Institute Vienna Circle, University of Vienna. Her research focuses on the life and work of Janina Hosiasson-Lindenbaum, a neglected figure in the philosophy of probability, and the historical and philosophical context of Rudolf Carnap’s inductive logic. She is also a former postdoctoral researcher at the University of Groningen and Ludwig Maximilian University of Munich.

• PhD in Philosophy (2017, LMU Munich & University of Groningen)
• MSc in Logic (2011, University of Amsterdam)
• MA in Philosophy (2010, University of Wrocław)
• BA in Philosophy (2008, University of Wrocław)

Marta’s research bridges formal epistemology, inductive logic, and conceptual spaces, with a special emphasis on unearthing the contributions of women in analytic philosophy. She has advanced novel Bayesian models for analogical reasoning and explored the geometric foundations of Carnapian inductive logic. Her work often intersects with the legacy of the Lvov-Warsaw School, focusing on Janina Hosiasson’s role in shaping early confirmation theory.

Her recent publications (2024–2022) emphasize analogical reasoning, historical contextualization of inductive logic, and the interdisciplinary application of conceptual spaces. Key themes include the evolution of Carnap’s ideas, the role of women in analytic philosophy, and formal constraints on probabilistic reasoning.

• Marie Skłodowska-Curie Postdoctoral Fellowship (2023–2025)
• NWO Veni Grant (2020–2023)
• Bavarian Gender Equality Grant (2018–2020)
• Kristeller-Popkin Travel Fellowship (2018)
• Doctoral Fellowship at Munich Center for Mathematical Philosophy (2011–2015)

Marta has taught courses on analogical reasoning and Bayesian epistemology, and supervised BA theses at the University of Groningen. She actively participates in conferences like Progic and HOPOS, and maintains The Janina Project, an online archive recovering Hosiasson’s lost works.
