I am co-founder and Executive Director of the Heathmere Center for Cultural Engagement. I have taught philosophy for over 20 years. I co-founded the Gender Studies Minor at Gordon College, taught Ethics, Peace Studies and Conflict Resolution at Endicott College, and teach Ethics at Emerson College (Boston Campus) and in the Emerson Prison Initiative (Concord). After publishing my 3rd book in 2020, Overcoming Polarization in the Public Square: Civic Dialogue, I continue to write on the theoretical dimensions of dialogue. My current work defends polarization as fueled by a double dehumanization strategy directed at both others and oneself.
