I don’t think the hypothesis that there is an independent conscious person existing along with you in your mind (or whatever those people think they’re doing) is the best explanation for the experiences they’re describing. If they just want to use it as shorthand for a set of narratively consistent hallucination then I suppose I could be okay with saying a tulpa exists. But either way: I don’t think a tulpa is an abstract object. It’s a mental object like an imaginary friend or a hallucination. Like any entity, I think the test for existence is how it figures in scientific explanation but I think Platonists and non-Platonists are logically free to admit or deny tulpas existence.
