Parapsychology is simply a label. Many Scientists, admittedly of vastly ranging talents and approaches, have attempted to tackle a kind of perceptual reality experienced by many, many people. I myself can point to no demonstrable ‘evidence’ for a ‘paranormal’ aspect to this altered state of consciousness but there again how are we to define paranormal? Surely we must have some concept of normality in order to attribute this term? By paranormal do we not been ‘unproven’, and as a few previous posters have suggested many phenomenon have qualified as paranormal, then graduated to theoretical before being proven.
Essentially then we are dealing with attempts to scientifically investigate those phenomenons which have been the focus of mystics throughout the centuries. Some fascinating neuro-biological research undertaken by Andrew Newberg et al. suggests that such mystical experience has a locus in the brain itself, and further this brain function is unique to such experience. These findings, along with the link to certain types of epilepsy which effect this brain area and create religious hallucinations, have been taken as confirmation that spiritual experiences are in fact a kind of mental disorder. You can however argue the opposite and say that the brain appears to have a hard wired capacity for such experience and those who have followed a spiritual path are able to access this.
Many philosophers and scientists believe in the concept of a holistic universe, an interconnected web of phenomenon within which mind and consciousness does not stand apart in a dualistic Cartesian sense. Quantum physics, and particularly the none locality of the collapse of the wave function, has often been used to put forward such theories. Placing mind in such an interrelated relationship with the physical universe does suggest the possibility that mental states could effect physical ones, and thus minds could have none verbal contact and, perhaps, contact to other realities, times and spaces (considering the relativity and fluidity of all these concepts in the totality of the universe). Quantum theory however is by no means a sure foundation for such theories and much criticism abounds for attempts to draw the kind of conclusion I have just suggested. For example John Bells theorem suggests that whilst sub-atomic particles can collapse from their state of potentiality as either a wave of localised particle, this occurring when the particle is excited by contact with other particles, in such a way as to breach Einstein’s principle of the speed of light being the maximum attainable by any object (essentially a collapsing wave function in an atom in my brain can bring about a collapsing wave function on Mars, in your head or on the surface of the sun). However Bell asserts that this function does not allow for a transfer of information, a common critique of ‘quantum consciousness’.
Whatever conclusions you draw from Quantum physics, and I would urge you to do your own research as it is a fascinating area, one thing which can be said is that the physical existence we all take for granted is based on some pretty ‘weird’ science. Science which is counter Newtonian, and certainly throws out the baby of a mechanistic, materialistic world view with its revolutionary bath water. So what is normal? A universe in which matter does not exist, or not exist, but show tendencies to do so, in which matter can appear from nothing and return to nothing?
Studying what mystics have long claimed is an experiential connection to the totality of existence, I would argue, seems a logical step in attempting to come to grips with a key aspect of human experience. Our sense of existence itself, how our brain and mind have evolved to cope with this concept and whether or not this capacity allows enhanced perception, and if so to what extent; is this perceptual range beyond what has previously been thought possible? (psychical ability, ESP, etc, etc.)
The difficulty in this endeavour is that experience is thought to be a none-physical domain and cannot therefore be studied directly in a way which offers the kind of validity one, as a sceptic, could reasonably demand in order to be convinced. Indeed the burden of proof always lies with those who make extraordinary claims, and rightly so. However I would simply ask that for those who reject parapsychology out of hand, do you do so on the basis of a sound analysis of methodology, having assessed the many attempts to bring replicablility and validity into this methodology; is this assessment an open, objective and free minded act by an enlightened rationalist who has closed off no possibilities?
If so, I must concede that on balance no earth shaking break through in this field has as yet been made. My own contention is that a new paradigm of science must be reached before such a breakthrough may be possible. This paradigm will be one in which an equal role will be given to experience and the old dualism is finally laid to rest. I do suspect however that much sceptical ‘critique’ is in fact ignorance, intellectual poverty of aspiration and childish name calling. I would welcome an adult debate however, and hopefully I’ve given us a few starting points!
