This episode was mostly recorded 2 years ago- in this show I provide the warrant for the 2nd Premise of my argument, namely that the Principle of Sufficient Reason as defined as every "thing" that exists has a sufficient reason/explanation of its existence, either in the necessity of its own internal nature or in an external cause.

Note, due to time constraints, I haven't done much editing on this one, so it somewhat reflects an outdated version of my argument (for e.g. I speak of my first premise as though it said the universe was "an existing thing" as opposed to a "contingent existing thing" or I say PSR applies to "things" but only mention substances rather than saying it applies to all three types of things- substances, heaps and property-things).  That said, despite some little modifications I would've liked to make, by in large the arguments presented are perfectly as I would have presented them today.
