Non-existence

[Jon Paul]

No it is not meta-ontology and metaphysics ... it is straight forward logic and reason.

It is meta-ontology because you are speculating beyond the fact of being into the evolution of being, and already proposing more ontological complexity and extensiveness than a solipsist.

There is no reason why our minds exist? Yes there is ... they evolved as a function of the spare "computing" power of our brains and became evolutionarily useful. Although I accept there is a lot to be learned about that and how it happened there certainly is NO EVIDENCE whatsoever to suggest that mind exist independently of body, brain or physical supporting infrastructure.

Again, all those things are metaontological deductions about the ontogenesis of your own mind based on the very sense-data that the solipsist believe makes up the only existing ontological reality, which don't exist independently of the mind, but only in the conscious experience of the mind.
