We explore the surprising compatibility of Internal Family Systems with a Thomistic understanding of the human person. The modern pioneer of parts work, Richard Schwartz, originator of IFS harmonizes with the medieval angelic doctor of the Church, St. Thomas Aquinas. Join Thomistic philosopher Dr. Anthony Flood, Catholic psychologist Dr. Eric Gudan and me, Dr. Peter, as we discuss how the goodness of IFS can be modified and grounded in the excellence of a Thomistic anthropology.   For the full video experience with all our visuals, gestures, and graphics, and for conversation and sharing in the comments section, check us out on our YouTube channel here:  www.youtube.com/@InteriorIntegration4Catholics
