In his article “Does the Eternal Soul Exist?”, Michael Graziano describes a condition known as hemispatial neglect as an entryway in to the conversation of whether the soul exists and what part our brains play in manifesting it.
I applaud the attempt.
To even grapple with the question takes cajones. The soul is ephemeral, divine, unknowable and the brain is a mysterious and marvelous organism but I doubt all the scans and tests in the world will be able to prove the existence of a soul let alone if it’s eternal.
The soul is information of a special kind, wrapped up into a complex structure, instantiated in the circuitry of the brain.
It is quirky and individual to each of us, and is precious because it is not eternal.
