Leibniz’ Cosmological Argument

Leibniz’ Cosmological Argument is one of the strongest cosmological arguments for the existence of God. We have a series of posts on the LCA here. The full argument is:

1. Every contingent fact has an explanation.
2. There is a contingent fact that includes all other contingent facts.
3. Therefore, there is an explanation of this fact.
4. This explanation must involve a necessary object.
5. This necessary object is God.

Of course, each point of this needs explanation and defence, so I have done so here (note that the part descriptor does not correspond to the point descriptor):

• Part 1 – Point 1: The PSR
• Part 2 – Points 2 to 4
• Part 3 – Point 5
• Part 4 – Responding to 3 important challenges
• Part 5 – Responding to common objections
