  3. So, the physical cosmos has a cause of its existence. (By 1 and 2)
  4. The cause of the physical cosmos is not physical (on pain of circularity). (Premise)
  5. So, the physical cosmos has a non-physical cause. (By 3 and 4)

The Physics Argument for 2

  1. According to our best science, the physical cosmos has a beginning. (Premise)

The Finitism Argument for 2

The Successive Addition Argument for 2

  1. If an infinite past is possible, then someone could have been counting down from infinity and finishing today.
  2. Necessarily, if someone were counting down from infinity and finishing today, there would be no explanation for why he finish today.
