The Philosophical Collaborations conference series, created by the Philosophy Department of Southern Illinois University Carbondale in 1993, was designed to fulfill two main objectives: (i) to foster a collaborative model of research in Philosophy, and (ii) to enhance graduate level education by promoting further faculty mentoring and the interaction between faculty and graduate students.

Professor Robert Hahn created the conference series and organized and supervised the annual series for 30 years from 1993 to 2023.
