The actual human experience.
The reason why your kids would be upset if you told them your love is just brain chemistry.
I don't think anyone here has stated that love isn't valuable simply because it can be explained as physical processes happening inside a brain.
"spiritual" people always seem to assume that and I don't really get why.
As if things like "love" can only be valueable if there is some supernatural non-physical component involved.
My loyalty, love and attachment to me kids is how I experience it. Regardless of how that loyalty, love and attachment is explained.
It matters not to the experience and reality of it.
It kind of reminds me of this documentary about human creativity from a neurological perspective. It featured Sting.
They put him in an MRI scanner and had him compose a melody in his head while in there, to see which parts of his brain light up.
They compared that with non-musicians. As it turns out, there was a specific area of his brain that was lighting up and this didn't occur in non-musicians.
He then asked the neurologists "
So you are telling me that this little flickering on this screen is what is my musical talent?"
The neurologist confirmed.
Sting got upset, stood up and left.
I don't get that. It doesn't diminish his musical talent. It doesn't make his music any less good or special.
It's just that he wanted it to be some kind of "mystical" or "spiritual" thing.
Ironically, it's just ego.
