...It would be nice if you could define what a mind is and quit trying to be condescending....
Some people bring condescension onto themselves.
And this has been covered, there is no necessity to define what a mind is to say there is one.
All that is necessary is first hand experience of one.
It is impossible to experience things that don't exist.
If one has the experience of a mind then mind exists.
My experience of mind is clear to me. I don't have the slightest idea how it is possible for a person to engage here without the experience of their mind being clear to them.
THAT is what needs explaining.
How is it possible for a thing with a mind to not know they have one? What is their blindness?
