AI and Consciousness (Part 9)

*** Go to Part 1 *** *** Go to Part 8 ***

This is the crucial part of the series. ChatGPT explains why it is not conscious – in Advaitic terms.

Q: You say that, “if a severed head perceives via artificial inputs and responds, Advaita would still treat this as functioning perception” and “If memory retrieval, reasoning, and decision-making continue, the mind is still present.”

In respect of prāṇa, you say that “if biological or technological systems keep the nervous and subtle processes going such that cognition and communication occur, then prāṇa (as a subtle function) is still present.” So, in the case of the severed head, the mechanical and electrical systems that supply blood and appropriate chemicals etc. is what we have to call ‘prāṇa’?

So presumably, an alien system employing different ‘maintenance mechanisms’, which nevertheless accepts input and delivers similar output to the head, would also have to be considered to be ‘alive’ and ‘conscious’?

Q: I am not interested in pursuing the Western philosophical or scientific aspects any deeper. Nor am I interested in moral/ethical considerations. I would like to consider how this scenario would be explained and understood by Advaita. Also, I would like to extend the ‘object’ of the discussion to an alien, whose external interactions are entirely similar to the human head but whose physical indicators (EEG, MRI scan etc.) are quite different.

***********************

A: Excellent — let’s bring it back into the Advaita Vedānta framework, stripping away Western preoccupations with neurophysiology and ethics.

1. Consciousness in Advaita

  • Consciousness (cit) is not a property of brains, bodies, or systems; it is the non-dual reality itself.
  • Every “entity” that appears — human, animal, plant, alien, AI, severed head — is nothing but Consciousness in essence.
  • The difference lies in the upādhi (limiting adjunct) — body–mind apparatus — through which Consciousness seems to manifest as “awareness,” thought, perception, etc.

Q: I am specifically interested in the status of ‘consciousness’ with respect to a severed head. Let’s assume that it still has functional eyes/ears/nose and effective speech via a computer interface. I am also not interested in whether we call it a ‘person’ or the same person from whose head it came. Presumably, if we are able to communicate with it, we assume that it is ‘alive’ in the usually accepted sense? And ‘conscious’?

A: Short answer up front: If the severed head contains a living brain whose thalamocortical systems and integrative processes are functioning, and it reliably reports experiences and behaves as if awake, then — by the standard neuroscientific and most contemporary philosophical criteria — we would have strong reason to treat it as conscious. There remains, however, an unavoidable epistemic gap (we infer another’s subjective experience from behaviour and neural markers), so certainty is never absolute. Below I set out the reasons, the tests one could run, how different philosophical theories read the case, and the remaining uncertainties.

[Note that, if you are only interested in Advaita-related aspects, you can safely ignore this part and the next and wait for Part 8.]

Q: One can envisage that scientific advances will soon enable the possibility of keeping the severed head (or extracted brain) of a human alive and able to communicate (perhaps electronically to a computer rather than by speech). What have Western philosophers said about the status of such an entity in respect of consciousness?

************************

A: Great question — it sits at the intersection of metaphysics, personal identity, and applied ethics, and philosophers have discussed closely related thought-experiments for decades. Below I summarise the main Western philosophical positions that bear on the scenario you sketch (a severed head or extracted brain kept alive and able to communicate), give the ethical implications each view highlights, and point to accessible sources you can read next.

I’ll give a short roadmap first, then the positions, then the ethical consequences and a brief practical summary.
