Interdisciplinarity is a buzzword in scientific and societal debates. Challenges such as climate change and the SARS-Cov-2 pandemic require perspectives from a multitude of domains. The reflection on interdisciplinarity raises an opportunity to rethink the place of philosophy in the architecture of the sciences. Is philosophy a separate perspective in interdisciplinary science, what can it offer and do philosophical problems require interdisciplinary solutions? Or is every philosophical problem itself necessarily interdisciplinary? We kindly invite you to reflect on these and related questions at the Philosophy in Interdisciplinary Research Conference 2022 (PIRC2022) and to explore the value of philosophy in interdisciplinary science.
