## Resource

Prof. Gregory Doolan explains how Aquinas uses philosophy to show that angels are real immaterial beings—pure forms with intellect and will—whose place in creation can even be understood in relation to the famous “head of a pin” question. This lecture was given on February 5th, 2026, at Harvard University. To make a gift this June, visit  https://truth.thomisticinstitute.org/pod . About the Speaker: Gregory T. Doolan is Associate Professor in the School of Philosophy at the Catholic University of America (CUA).
