No matter how closely you examine the water, glucose, and electrolyte salts in the human brain, you can't find the point where these molecules became conscious.
We talk about quantum weirdness and things being in two places at once, but it all involves atoms and molecules, stuff we don't normally interact with.
To say that my anxiety is reducible to the ions in my amygdala is as limiting as saying that my personality or my soul is reducible to the molecules that make up my brain cells or to the genes that underwrote them.
People don't even understand that every bit of our food was once alive. We take another creature, plant, animal, microorganism, tear it apart in our mouths. And incorporate those molecules into our own bodies. We are the Earth in the most profound way.
You may have heard the world is made up of atoms and molecules, but it's really made up of stories. When you sit with an individual that's been here, you can give quantitative data a qualitative overlay.
