A good starting point would probably be that the difference between something with a mind and something without a mind is pretty obvious. God and lack of god are suspiciously similar and no one’s come up with metric of differentiation that meets objective standards acceptable by everyone.
Because our senses are limited, and it’s locked up in the skull. With the right equipment we can see the mind - we don’t understand much of what we are seeing, but we do see it.
No. God is logically contradictory, physics breaking, completely lacking in evidence for it either being possible or existing, a myth created by primitives, and obvious wish fulfillment. The mind isn’t.
Yes it is; a mind is a living, functioning brain. It’s a complex lump of matter and energy, not magic.
I can very definitely sense “mind” indirectly – by communicating with one. I’m communicating with several minds right now. When or if some of them respond (“Gaw, yer fool of it!”) I will have interacted with human minds.
Sure, this doesn’t answer Cartesian doubt. Maybe all y’all are robots, or AIs, or demonic deceivers, or illusions cast by the shadow of mana. But that isn’t a particularly interesting way to look at it.
Solipsism should always be footnoted…and then we move on, discussing reality as if it existed.
But all of us are aware of our thoughts. I’m aware that I’m writing these words, thinking about what I’m going to say next. You are reading these words consciously, and thinking about what your response will be.
Furthermore, we are aware of our mind when we lose consciousness. Our when we pull ourselves out of a dream.
Or when we enter into altered states of consciousness, via drugs, alcohol, etc. Or when we enter into altered states of consciousness via strong emotional stimuli. Or when we develop mental illnesses. People who suffer from severe clinical depression have a very strong personal awareness of the mind.
Meanwhile…none of this pertains to God. Dead silence, at least for most of us. And those who have heard the voice of God never report God having said doodly-squat of any worth or meaning!
Or for that matter even the same thing from person to person. And of course there’s all the people who have religious experiences that don’t involve God for the simple reason that he’s not included in their religion. Only a subset of religions believe in a God, singular.
