The Argument in Sum
  1. For any effect, there must be as much reality (positive properties) in the cause as there are in that effect
  2. Ideas may fail to correspond to something outside of me, but their cause must contain as much reality as the thing they are ideas of
  3. I have an idea of God as the most real thing
  4. The source of this idea of God must be at least as real as God
  5. The thing at least as real as the most real thing is the most real thing

  7. God exists
