Department of Philosophy

Professor Ludwig works on foundational issues in the philosophy of language (esp. logical form and semantics), the philosophy of mind and action, epistemology, and metaphysics, though his interests extend to every area of philosophical inquiry. He taught at the University of Florida from 1990 to 2010 and was the Colonel Alan R. and Margaret G. Crow CLAS Term Professor from 2008-2010, when he joined the philosophy department at Indiana University, Bloomington.

He is the editor of the volume on Donald Davidson (2003) in the Cambridge Contemporary Philosophy in Focus series, and he is coauthor with Ernie Lepore (Rutgers) of Donald Davidson: Meaning, Truth, Language and Reality (OUP 2005) and Donald Davidson's Truth-theoretic Semantics (OUP 2007), and co-editor with Ernie Lepore of A Companion to Davidson (Wiley-Blackwell, 2013). He is the author most recently of two books on collective agency: From Individual to Plural Agency: Collective Action 1 (OUP 2016) and From Plural to Institutional Agency: Collective Action 2 (OUP 2017), and co-editor with Marija Jankovic of the Routledge Handbook of Collective Intentionality (2018).

He edits the Collective Intentionality category at Philpapers.
