This article focuses on the questions of academic freedom, scholar activism, public science, and social engagement. The five authors represent scholars from different disciplines and scientific paradigms as well as diverse gender, sexual orientation, nationality, ethnic, and class backgrounds, yet they share a joint passion for academic 'activism'. The paper, therefore, reflects a multitude of transdisciplinary perspectives and positionalities. This dialogue was born out of the group's desire to investigate the role of scientists in public and political matters, including engagement in social justice. The interdisciplinary nature of the dialogue allows for comparisons between how activism is defined, perceived, practiced, and considered (un)welcome in the disciplines of Sociology, Psychology, Law, Media Studies, and Medical Sciences.
