I was thinking about the idea of two individuals existing as one - can you be the same thing but also be individuals? Is there a case where that's true? Computers have processes and virutal machines, but those things define lines and create "others" that are kept separate. Maybe in the case of two people working on a problem together, they kind of form a "combined being" through being connected with language and all that, and the output of that, the papers they write, are that being's words/language?
I guess at that point a tulpa would be "an individual and not an other" to the host only in the case that the tulpa was part of the host's "output and thought process" - like maybe your tulpa is helping you think or something, and if they were gone you'd be changed as a person in terms of how you think/what you say and do?
I can't speak much from a group-person relationship perspective. I believe there's a difference between being a 'collective individual' and being an individual, but that's just based on my feelings and not any observations or deep thought even. I think when you see two people as one, you ignore the inconsistencies and you strip away what makes them unique. For the company example, some people go as far as strip away the human from the spokesperson. However, I don't have any counter arguments for any counter examples, I don't have a strong opinion on that.
I was thinking about this from an 'if parallel processing was real' standpoint and I don't know it matters? For example, if you had a singlet who managed to create a second version of themself and the two versions thought in parallel, would they be different or are they still the same person? I'm inclined to believe the latter because I think regardless of what happens in your brain, how you label who is what really matters.
