I'm not aware of any established concept or theory referred to as "post-Bionian field theory" (BFT) in the field of psychoanalysis or related disciplines up to my knowledge cutoff date in September 2021. It's possible that new developments or theoretical frameworks have emerged in the field of psychoanalysis or related areas after that date, and I would not have information about them.
If "post-Bionian field theory" is a term or concept that has been developed or gained significance after my last training data in September 2021, I would recommend consulting more recent literature, academic sources, or experts in the field to gain a better understanding of what it entails and its theoretical underpinnings.
It's also possible that the term "BFT" could be used in other contexts or fields with a different meaning, so it's essential to clarify the specific context in which you've encountered this term for a more accurate explanation.
