Ok. I have a possible answer, thanks to a breakdown of Chinese. I’ll just copy a few:
Open heart. 1. 開心 (kai-xin) — Happy
Hurt heart. 2. 傷心 (shang-xin) — Sad
Small heart (timid, not brave) 3. 小心 (xiao-xin) — Careful
loss heart 4. 虧心 (kui-xin) — Guilty
So if soul translates to heart and heart is internal emotions, how can the soul be known in a simulation?
Through expression of emotions.
The only question left is: Are they honest emotions (soul) or acting?
For that we can tie the variables generating the emotions to their sources.
In a human body, we can tie them to measurable physiological symptoms to a degree.
In a simulation, to whatever sources of the simulation we have access to.
Are the contents of a soul ONLY consist of “heart” or “emotion”?
Well, it could mean “core”, and if you can find the source of the metrics for your emotions, whether in a simulation or not, it’s likely you can also find the source of the metrics for whatever rests upon the core, which may be factual knowledge, etc.
