If you cannot, then you and I are individuals. If you can, then you and I are not individuals, but one.
Hint: the Scriptures speak of several instances of oneness where this is possible. Oneness in Him, with other believers and with a spouse - all of this is the same "mystery" (Ephesians 5, I Cor 2, John 15-17, Romans 8, Col 3:3 and I Cor 12)
Here's the question I'm pressing you on: If there are two (or more) non-corporeal, non-spatiotemporal human souls, how is that they are two (or more) and not just one? If they possess no physical characteristics (or relations) at all, and no spatiotemporal locations at all, how can they be distinct?You can observe this for yourself by doing a simple thought experiment: meditate as deeply as you can and then tell me what I am thinking.

I'll agree that we're individuals, two and not one. But, clearly, I'm over here and you're over there (spatial apartness), and we're both corporeal. What I'm asking is, how can two souls be distinguished if they're disembodied (lack corporeal characteristics and relations) and lack both spatial and temporal situatedness?
I'm particularly looking for a response that predicts the correlation between brain states (drugged, damaged, diseased, etc) and behavior. I would like, for example, to see a non-physical or extra-physical explanation for the inability to form long-term memories. Please bear in mind that there is a prefectly functional physical explanation, complete with data, photographs of neural connections, specific sites of injuries, and so forth. Your explanation would need to predict some phenomenon that is not predicted by the standard brain model.
