Stuart Hameroff's ideas.

Penrose seems to only believe in Mathematical (and maybe Moral) Platonism as his only deviation with Materialism.

If anything I'd say Penrose has influenced Hammeroff into thinking a complete physics would extend, at least to some degree, even to "deeper planes of existence".

If that is so, I can't imagine Penrose liking the direction of Hameroff's more recent ideas. There must be some tension between the two.

I think Penrose is ok with speculation and people having different ideas than his own. He’s just firm on his own position which is why he calls it the “prejudiced view”.

I mean the very idea Objective Collapse has to be associated with consciousness relies on certain - incorrect IMO - beliefs about physics & causal closure. The better path, IMO, is to realize there just isn’t physical closure because there is [no] good explanation for causation in physics’ study of relations.

Has Hammeroff stated that any of the empirical evidence for the afterlife should be seriously considered and deserves further investigation?

For example, spirit communication through mediums, or NDEs, shared death bed visions, or reincarnation studies such as those done by Ian Stevenson?

Or is he just saying theoretically, according to his theory, disembodied consciousness might be possible?

What does he say about ESP?

I am trying to find some reason to say he is doing something good by helping society make progress toward universal acceptance our spiritual nature. 
If he is just saying that there could be a physicalist explanation for the afterlife, I see that more as trying to save materialism/physicalism than trying to promulgate spirituality.

Spirituality has implications of purpose and morality, it makes life meaningful in a positive way. I see physicalists/materialists like Hammeroff and Radin as preserving the meaningless, nihilist, negative aspects of materialist philosophy and therefore they are doing more harm than good. Their false beliefs if spread might take away the benefits from people who are inclined to spirituality.

I think we already went over this back in Jan. 2024. At that time I made the following remarks (at https://psiencequest.net/forums/thread-o...9#pid56129):

Hameroff in his own website describing the Orch-OR theory makes it pretty clear he is talking about the physical Orch-OR process generating consciousness, not receiving, transducing and transmitting it. See the following excerpt, from https://hameroff.arizona.edu/research-ov...20to%20the :

"In the mid-1990s Hameroff teamed with British physicist Sir Roger Penrose to develop the controversial theory of consciousness called “orchestrated objective reduction” – Orch OR theory – in which consciousness derives from quantum computations in microtubules inside brain neurons, quantum computations connected to the fine- scale structure of spacetime geometry.
...................................
In the mid 1990s we published the Penrose-Hameroff theory of ‘orchestrated objective reduction’ (‘Orch OR’) which suggests consciousness arises from quantum vibrations ‘orchestrated’ in microtubules inside brain neurons, orchestrated vibrations which are proposed to interfere, ‘collapse’ and resonate across scale, control neuronal firings, and generate consciousness."

This is still in his website, so he evidently still basically believes in a scientifically sophisticated way that the brain generates consciousness as the liver generates bile.

He's mentioned NDEs positively, and in a paper noted his acceptance of Bem's findings.

From my reading I would say he thinks there is a structural component to every aspect of existence, but these aspects go beyond the physical world and instead include planes of existence where Survival would be experienced.

For example, from the Quantum Soul paper he wrote with Chopra:

Unable to explain consciousness in the brain, conventional science ignores apparent evidence for NDEs/OBEs, rejecting even the possibility of their occurrence. There are, however, unconventional but scientifically valid approaches to consciousness, which may...accommodate NDEs/OBEs as well as possible conscious awareness after bodily death.

Such approaches explore strata of nature at an even finer scale than the chemical reactions and electrical signals relied upon by neuroscience, seeking convincing answers at the quantum level instead.
