Your different selves and split brain experiments

[JohnClay]

Luke 10:27 says:

Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind

So that seems to talk about four faculties of a person. Note that the Bible doesn't seem to say that the head was used during thought though neither did most other cultures at the time. Besides the heart, the Bible also talks about thinking with your gut (bowels) and kidneys (reins).

Then there's this kind of thing that Copilot said:

1. The Flesh (sarx)​

• Represents the sinful nature, the part of a person inclined toward sin.
• Opposes the Spirit (Gal 5:16–17).
• Cannot submit to God (Rom 8:7–8).

2. The Old Man / Old Self (ho palaios anthrōpos)​

• The person you were in Adam, before being united to Christ.
• “Crucified with Christ” (Rom 6:6).
• Not identical to “the flesh,” but closely related.

3. The Sin Nature​

• A theological shorthand for the capacity to sin that remains in believers.
• Battles against the new nature (Rom 7).

4. The Body of Sin​

• Paul’s term for the human body as a base of operations for sin.
• Distinct from “old man,” but connected to how sin exerts influence.

5. The Inner Man vs. The Outer Man​

• “Inner man” = the renewed, Spirit‑aligned self.
• “Outer man” = the decaying, mortal, sin‑affected self.

Anyway in split-brain experiments it looks like there is another self though it isn't capable of speech...

I wonder if that would be another instance of a sinful self.

Another interesting brain thingy is in cetaceans. (Whales, dolphins and the like.) They have unihemispheric brains; this allows one hemisphere of the brain to rest while the other remains awake. They are conscious breathers, so they need to have one side awake at all times. They found this out unfortunately when early captive dolphin surgeries, used general anesthesia which resulted in death due to respiratory arrest. Unlike us, they don't just automatically breath.
