What does John Paul II mean by self-determination?

A Day after St. John Paul II's feast day, Fr. Jacob and Fr. John riff on JPII's philosophical ideas of the human person as they try to come to a greater understanding of healthy self-determination tied to proper self-governance in light of truth. They discuss how man is in a way a "maker of himself" through his agency, and how man can make himself good or evil through his own will. But it is not all doom and gloom, through the perspective of gift and participation the ideas of JPII can help us retrieve proper agency toward virtuous living.
