I was asked to give a talk on this topic at the University of Birmingham at the beginning of March. I have done this once before (see link) and have ruminated on the issues before and since on this blog. I had so much running round in my mind-brain, whichever it is, that I needed to start organising my ideas in good time. Writing a blog post seemed a good way of helping in that process. The earlier post on Monday hopefully conveyed a sense of what actually happened. This is the second and last post attempting to express simply what I thought I might say!

I argued in Thursday’s post, which describes my journey from atheism to belief in God, that finding completely compelling empirical evidence in support or refutation of the possibility of a spiritual dimension will be vanishingly hard to come by. I said I would examine a typical example in this post.

Pim van Lommel’s research on near-death experiences is robustly attacked by Evan Thompson in his existentially philosophical treatise, Waking, Dreaming, Being which also claims to have turned my black swan, Pam Reynolds’ NDE, into a dead albatross.

Quotations from Thompson’s sceptical and Mario Beauregard’s convinced account will illustrate the problem. I’ll focus on the hearing issue, though that is by no means the only point of contention (readers of my recent post on this issue can skip this bit). Pam Reynolds had a tumour deep in the brain stem, surgery for which required a total shut down of her brain, drained of all blood and kept at a low enough temperature to fend off brain cell death within the time frame of the operation.

Thompson writes in Waking, Dreaming, Being (page 307):

Reynolds’s eyes were taped shut, so she wouldn’t have been able to see what was going on around her. Although she was wearing fitted ear plugs that delivered 40-decibel white noise to one ear and 95-decibel clicks every eleventh of a second to her other ear (in order to monitor her auditory brainstem response), she probably would have been able to hear the sound of the saw through bone conduction (as when you hear inside your head the sound of the dentist’s drill). On the basis of hearing the sound, she may have generated a visual image of the saw, which she described as looking like an electric toothbrush. She would have been familiar with the surgical procedure from the surgeon’s description and from having read and signed the informed consent form, and she would have seen the layout of the operating room because she was awake when she was wheeled in. [An alternative account posits that the theatre staff had hidden the instruments to avoid alarming her.] So she probably had enough knowledge to create an accurate visual and cognitive map of her surroundings during her out-of-body experience. Reynolds’s ability to hear what the cardiac surgeon said may seem less likely, but to my knowledge no one has tried to replicate the auditory stimulus conditions to determine whether speech is comprehensible through those sound levels or during the pauses between the clicks.

Pam reynold's surgeryBeauregard’s view is different (Exploring Frontiers of the Mind-Brain Relationship – page 132):

Sceptics will argue that when Reynolds saw the surgeon cutting her skull or heard a female voice say something about the size of her blood vessels, she was not clinically dead yet. Nevertheless, her ears were blocked by small moulded speakers continuously emitting 100-dB clicks (100 dB correspond approximately to the noise produced by a speeding express train). Medical records confirmed that these words were effectively pronounced (Seabom 1998). Moreover, the speakers were fixed with tape and gauze. It is thus highly unlikely that Reynolds could have physically overheard operating room conversation.

In terms of Reynold’s supposedly prior knowledge, it is perhaps also worth quoting Penny Sartori’s 2008 work in Swansea, quoted by Fenwick in a later chapter of the mind-brain book. In her study she was able to ask (page 148):

. . . whether the patients who said they left their bodies during the cardiac arrest were able to give a more accurate account of what happened during their resuscitation, than those who did not claim to have left their bodies or to have any memory of seeing the resuscitation. She asked both groups to describe what they thought had happened during the resuscitation and found that those who said they had seen the resuscitation were more accurate in their account of what had occurred than those who were simply guessing. This finding is important as it is the first prospective study which suggests that veridical information may indeed be obtained in some manner by someone who is deeply unconscious and who has none of the cerebral functions which would enable them either to see or to remember.

past-livesReincarnation:

Much later in the game I came back to giving reincarnation another look. It can’t really be ignored in any honest open-minded investigation. There is far too much evidence that suggests there are phenomena that invite interpretation as supporting reincarnation.

I explored reincarnation when I was investigating Buddhism and rejected it, so it is not only because my current belief in the Bahá’í Faith discounts it, that I am drawn to another way of interpreting the data.

Peter and Elizabeth Fenwick, in their excellent book Past Lives, have a whole section on this take on the issue. They also look at whether psi alone might be a sufficient explanation. Personally, though they do not close the door on that possibility themselves, for reasons concerning the degree of identification that the strongest cases exhibit (see below) psi does not seem to me the best candidate.

They then move on to what they refer to (page 278) as the ‘Cosmic Memory Bank.’ They describe ‘field theories’ and refer to Rupert Sheldrake’s idea of ‘morphic resonance.’ They add (page 279):

If memories (information) are held in this way they would exist independently of the brain and therefore be accessible to another brain which ‘resonated’ with them.

They accept that this could explain cases where (page 280) ‘more than one person remembers the same past life’ but feel that it is improbable that a child’s brain would be capable of resonating to an adult consciousness. They also feel that where memories of a past life display ‘continuity’ and ‘detail,’ this would not usually the case where psi is involved and for them accessing a universal mind would entail the use of psi.

The idea of a Cosmic Memory Bank appeals to me partly because this idea is to be found in other sources that I trust in different ways. Yeats refers to it as the Anima Mundi and Jung speaks of the ‘collective unconscious.’ The Bahá’í Writings refer to the ‘universal mind’ as when ‘Abdu’l-Bahá responds to a woman’s letter advising her: ‘to forget this world of possession, become wholly heavenly, become embodied spirit and attain to universal mind. This arena is vast and unlimited . . . .’

The introduction to Albright’s Everyman edition of Yeats’s poems puts his view succinctly (page xxi):

He came to the conclusion that there was in fact one source, a universal warehouse of images that he called the Anima Mundi, the Soul of the World. Each human soul could attune itself to revelation, to miracle, because each partook in the world’s general soul.

If we can accept this possibility, it provides, in my view, another possibly way of explaining the data which points also towards the possibility of reincarnation. Unfortunately, as always in this kind of area, greater certainty is inevitably elusive.

spiritual-brainWhere does that leave us?

In the end I’ve come to feel as Mario Beauregard does.

In The Spiritual Brain he refers in summary to the areas of exploration he has adduced which he feels a nonmaterialist view can explain more adequately (2528):

For example, a nonmaterialist view can account for the neuroimaging studies that show human subjects in the very act of self-regulating their emotions by concentrating on them. It can account for the placebo effect (the sugar pill that cures, provided the patient is convinced that it is a potent remedy). A nonmaterialist view can also offer science-based explanations of puzzling phenomena that are currently shelved by materialist views. One of these is psi, the apparent ability of some humans to consistently score above chance in controlled studies of mental influences on events. Another is the claim, encountered surprisingly often among patients who have undergone trauma or major surgery, that they experienced a life-changing mystical awareness while unconscious.

This paves the way for finding the idea of mid-brain independence credible.

He also refers to the work in neuroplasticity which I have also dealt with on this blog (2605):

Generally, Schwartz says, success with the four-step method depends on the patient doing two things: recognizing that faulty brain messages cause obsessive-compulsive behavior and realizing that these messages are not part of the self. In this therapy, the patient is entirely in control. Both the existence and the role of the mind as independent of the brain are accepted; indeed, that is the basis of the therapy’s success.

He ends up on Alvin Plantinga’s ground at one point (Kindle Reference: 2520):

We regard promissory materialism as superstition without a rational foundation. The more we discover about the brain, the more clearly do we distinguish between the brain events and the mental phenomena, and the more wonderful do both the brain events and the mental phenomena become. Promissory materialism is simply a religious belief held by dogmatic materialists…who often confuse their religion with their science.

conscious-universeIn addition, Dean Radin’s The Conscious Universe marshalls acres of evidence in favour of Psi, though it has been accused of overstating its case. He even quotes a sceptic in support of its rigour, thereby hopefully dismissing the spurious claims of dogmatic a priori sceptics (page 209):

Today, informed sceptics no longer claim that the outcomes of psi experiments are due to mere chance because we know that some parapsychological effects are, to use sceptical psychologist Ray Hyman’s words, “astronomically significant.” This is a key concession because it shifts the focus of the debate away from the mere existence of interesting effects to their proper interpretation.

There is enough here overall, I feel, to give all but the most died-in-the-wool materialist pause for thought. Even if you only give credence to ‘hard’ scientifically gathered evidence, it seems clear that the exact nature of consciousness is an open question rather than a closed case.

Let’s hope I conveyed all that clearly enough to get the point across to a roomful of psychologists!

Or was it back to the lion’s den again, perhaps.
