Mental states and processes like sensations are simply brain states and processes. But even though they mean something different and are spoken of differently in our language, they both refer to the same neurological event. There is no need to introduce supernatural or spiritual elements to explain existence. A naturalistic picture of reality is barren, devoid of the variety and beauty we encounter in experiencing reality. Guiding the universe is a purposive mind, God.
Introspection reveals the reality of mental things that are accessible only privately.
Because the mental and the physical can be conceived as distinct, it is possible that they are distinct. According to J. L. Austin, the point of referring to what is real is not to identify reality but to distinguish how we normally differentiate between what is real and what is not real.
