Christopher Roser

Christopher Roser is a philosopher specializing in Ancient Philosophy, Moral Responsibility, and Social Epistemology with a PhD from Humboldt University Berlin. He served as a Lecturer in Philosophy at Humboldt University Berlin (2020-2021) and as a Research Fellow at the Cluster 'Philosophy, Science and the Sciences' in 2020, focusing on rationality, argumentation, and historical roots of moral responsibility in Classical Antiquity.

His educational background includes:

• PhD in Philosophy, Humboldt University Berlin, 2019
• MPhil in Classics, University of Cambridge, 2012
• MPhil in Philosophy, Logic, and Theory of Science, Ludwig-Maximilian University Munich, 2011
• Visiting Student in Philosophy, University of Oxford, Queen's College, 2010

Roser's research examines the interconnection between rationality and moral responsibility through historical analysis of Classical Antiquity (particularly Aristotle and predecessors), while addressing contemporary social epistemology issues including epistemic justice, fake news, and the societal value of argumentation. His work bridges ancient philosophical frameworks with modern ethical and epistemological challenges.

His 2021 publication analyzing Plato's Socratic dialogues demonstrates his methodological approach of using paradigm-based analysis to distinguish dialectical and rhetorical argumentation, reflecting broader research trends connecting historical argumentation theory to current debates about rational persuasion in democratic discourse.

Dr. Roser has received significant recognition through:

• Doctoral Fellowship by the German Research Foundation (DGF)
• Cambridge Trust Scholarship
