As you may know, I working on a master’s thesis on new philosophical arguments for God developed in recent natural theology and philosophy of religion, under the supervision of the Dutch philosopher Emanuel Rutten. Today I did a little work on one of Alexander Pruss’s ontomystical arguments, as found in his “Samkara’s Principle and Two Ontomystical Arguments” (2001), and his article has helped me come up with a number of arguments which may or may not be novel arguments for God. If you have encoutered arguments along these lines elsewhere or see ways of improving the arguments, please get in contact. In any case, you can find three potentially new arguments for God below:

An Argument from Religious Experience

1. A religious experience has occured which is such that it is possibly caused by God.
2. If (1), then God exists in at least one possible world.
3. God is such that if God exists in one possible world, God exists in all possible worlds.
4. If God exists in all possible worlds, God exists.
5. Therefore, God exists.

A Cosmological Argument

1. An event has occured which is such that it is possibly caused by God.
2. If (1), then God exists in at least one possible world.
3. God is such that if God exists in one possible world, God exists in all possible worlds.
4. If God exists in all possible worlds, God exists.
5. Therefore, God exists.

Another Cosmological Argument

1. A being exists which is such that it is possibly caused by God.
2. If (1), then God exists in at least one possible world.
3. God is such that if God exists in one possible world, God exists in all possible worlds.
4. If God exists in all possible worlds, God exists.
5. Therefore, God exists.

More arguments along such lines can of course be drawn up. Arguments on the basis of the following additional argument for God could also be drawn up, which does not necessarily take something in the actual world as starting point:

1. There is an x in some possible world such that x is possibly caused by God.
2. If (1), then God exists in at least one possible world.
3. God is such that if God exists in one possible world, God exists in all possible worlds.
4. If God exists in all possible worlds, God exists.
5. Therefore, God exists.
