In this series of episodes, Pat begins to develop the famous argument from contingency for the existence of God.
- Everything that exists has an explanation for its existence, either in an external condition or necessity of its own being.
- If the universe has an explanation for its existence, that explanation is God.
- The universe exists.
Part 1 is an overview of the argument and brief defense, part 2 is a more detailed defense of premise 1 which is a modest form of the principle of sufficient reason.
