We
ought not pass on from this topic without mentioning the scientific study of
reincarnation so-called. The attempt to demonstrate the plausibility of rebirth
“scientifically” can be summarized as scant anecdotal evidence amounting, in a
very few instances, to a weak prima facie
case that upon examination quickly collapses. In answer to the standard
question, “How do you account for so-and-so’s vision, memory, ability,
information?” I refer readers to the standard reply, that on a case-by-case
basis it is in practice always possible to find a more plausible alternative
hypothesis. Countless books and articles have been written about the inadequacy
of the “proofs” of reincarnation. I will not recapitulate their contents here.
I
will, however pause long enough to draw your attention to one interesting
feature of the problem facing advocates of karma-theory whenever they try to
explain an individual’s apparently impossible knowledge. The central nervous
system of the human being is a powerful, convincing and occasionally deceptive
generator of extraordinary and even impossible events. We have abundant
evidence of compelling and yet utterly subjective “experiences.” The data are derived
from the study of dreams, drug-induced states, advanced visualization
techniques, schizophrenia, and sensory deprivation.
For
most people, most of the time, it is possible to distinguish dreaming from
waking life. It is even possible for the insane to sometimes discriminate
hallucinated objects, voices and persons from those that are physically
present, as the mathematician John Nash taught himself to do. It is unclear, to
say the least, what criteria might be used to distinguish experiences of the
astral plane from, let us say, spontaneously arisen visions due to prolonged
fasting and dancing, or excessive intense concentration, or the unwitting
ingestion of hallucinogenic bread mold. How, for that matter, are we to judge
whether an unconfirmed verbal report is based on recollection of a past life,
demonic possession, or acts of imagination? If most of us vastly prefer the
latter explanation, it is because it requires far less in the way of groundless
speculation and dovetails better with what we know to be relatively certain about
the world.
