Just learned something interesting in biology...
Two biology theories which have theological implications:
Preformationism: That all the structures of a being are present in miniature form before the being fully developed.
Epigenesis: That each being is created "from scratch," as in, there are no miniature components which correspond to the complex structures that arise.
Which view does the Abhidhamma presentation of rebirth correspond to? Or neither?
To put this into more specific Pali terms: Is the body or consciousness of a living sentient being the same or different than the gandhabba or rebirth-linking consciousness?
I suspect Abhidhamma goes against both theories, because both seem like retrospective eternalism and annihilationism. That is, Preformationism suggests, "I have always existed in the past (in a different form)," while Epigenesis suggests, "I did not exist in the past." But the Buddha's teaching has no regard for self.
