This talk was given at the 6th Annual Catholic Medical Association Medical Student and Resident Boot Camp at the University of St. Mary of the Lake, Mundelein, Illinois on June 21, 2018. I begin with a very brief discussion of the Catholic understanding of love and the meaning of suffering and death, then define the terms needed to have a debate about euthanasia, then show the Catholic view on euthanasia, contrasting it with the vitalist and pro-euthanasia views. After that I have a discussion, including works of art, about Ars moriendi (The art of dying) and Memento mori (remembering your death), which are two rich Catholic traditions that have been lost, and which would be good to regain. There is about 20 minutes of q&a at the end.
