Another Stupid Philosophical Question:

"Do mental events cause physical events?"
(and vice versa)

This illustrates a fundamental confusion faced by those who want to naturalize the mind, as if it weren't something already quite natural. Doesn't phenomenal consciousness provide us with a very good understanding of how reality operates?

This is why I am a neutral monist and panpsychist.

A Stupid Philosophical Question:

"Are indexical properties causally efficacious?"

God?

The idea of God is a manifest contradiction, and we all know that anything follows from a contradiction. Perhaps this is the origin of the saying, "With God, all things are possible." (Matthew 19:26)
