The perception of reality by biosystems is
based on
different, and in certain respects more effective principles than those
utilised by the more formal procedures of science. As a result,
what
appears as random pattern to the scientific method can be meaningful
pattern
to a living organism. The existence of this complementary perception of
reality makes possible in principle effective use by organisms of the
direct
interconnections between spatially separated objects shown to exist in
the work of J.S. Bell.
1. INTRODUCTION
Bell(1,2)[4] has given arguments that appear to
demonstrate
the existence of direct interconnections between spatially separated
objects.
But at the same time there are arguments(4-6) that appear to show that
no real physical manifestations of these interconnections actually
exist. The thesis developed in this paper is that it is only from
the point of
view of quantum mechanics that these connections appear to be
unphysical,
and that there is a different, complementary point of view, one
associated
specifically with the activities of living organisms, in terms of which
the interconnections may be very concretely real, and capable of being
put to practical use.
The logic of the complementary point of view to
which
reference has just been made is that the activities of living organisms
are governed by predominant principles (survival, and optimality of the
conditions of life) different to those of the scientist (conformity to
certain restrictions that are considered necessary for "good" science).
The perceptual processes of organisms (e.g. processes such as vision)
perform
their functions in general very effectively, but in a way that is hard
to delineate in rigorous scientific terms. It will be argued that as a
result of this difference the knowledge
possessed by
biosystems
and the knowledge possessed by science are qualitatively different,
leading
to an ability of life to make use of Bell's non-locality in a way that
is not possible in the different situation of a controlled scientific
experiment.
The discourse that follows begins (Sec. 2) with a
review
of Bell's theorem, discussing in particular the antithesis between the
way that Bell's argument appears to demonstrate the existence of direct
action at a distance, while at the same time quantum calculations
lead
to the result that any such effects will disappear under statistical
averaging.
Experiments on certain unusual human abilities(7,8) suggest that the
non-local
effects do not invariably disappear under averaging, a result that the
present paper seeks to explain.
The explanation proposed here involves the issue
of exactly
what kind of randomness is being presupposed when one performs such
statistical
averaging. An answer to this question in general terms is provided by
causal
(non-statistical) models of the phenomena of the quantum realm such as
that of Bohm(9). This kind of interpretation assumes the relevance of
particular
probability distributions in an appropriate phase space. The
possibility
that one needs in general to deal with coexisting multiple
representations
of reality (complementarity) is then considered, the implication being
that different kinds of probability distributions to those relevant to
quantum mechanical predictions may be appropriate in cases such as
those
involving biosystems. From the point of view of a biosystem itself,
this
possibility translates into one that biosystems can have more
discriminative
knowledge of nature than is obtainable by quantum measurement. As a
result
of this higher degree of discrimination, the evolutionary and
developmental
processes characteristic of biosystems can, given suitable initial
conditions,
lead to focussed probability distributions that make possible the kind
of human abilities (i.e. psi functioning) to which reference has been
previously
made.
2. BELL'S THEOREM AND NONLOCAL CONNECTIONS
We first review Bell's
theorem. Its domain of relevance
is of a type of system, which we shall refer to here as an EPR-type
system,
first discussed by Einstein, Podolsky and Rosen(10). EPR-type systems
are
systems wherein a quantum object breaks up into parts which after
separating
are observed by measuring instruments that have no links of a type that
can transmit information by normal means to each other. A typical
example
of such a system, which has been studied experimentally(11), involves
measurement
of the correlated polarisations of the photons emitted in a two-photon
decay sequence. Bell's theorem consists of an inequality applicable to
the correlations observed in a range of different measurements, and
from
it one can derive the corollary that no local model of physical reality
can exist whose statistical predictions would be in agreement with
those
of quantum mechanics: in Bell's own words(1), if nature behaves in
accordance
with the statistical predictions of quantum mechanics then "there must
be a mechanism whereby the setting of one measuring device can
influence
the reading of another instrument, however remote". Experimental
results,
while not being totally conclusive, are such as to point towards this
conclusion
being valid.
The existence of such remote influences or
connections
is suggested more directly by experiments on phenomena such as
telepathy
(the direct connection of one mind with another) and psychokinesis (the
direct influence of mind on matter), both of which are examples of
so-called
psi functioning or psychic phenomena. The reader interested in learning
about these phenomena (which are often disregarded by orthodox science)
is referred to the recent article by Radin and
Nelson(8) which analyses
experiments relating to them, as well as to the references cited
therein
(and especially those relating to the publications of R.G. Jahn and collaborators,
and of H. Schmidt), and to Ref. 7[5].
3. DO THE INTERCONNECTIONS PERSIST UNDER
STATISTICAL AVERAGING?
Ordinary quantum mechanical calculations, if one
excludes
from consideration proposals such as that of Walker(12) that contain
special
ad hoc modifications to the conventional theory, do not seem to provide
any clear mechanism leading to the occurrence of phenomena where the
effects
of non-local connections are manifested directly. Indeed, conventional
quantum mechanical calculations(4,5) suggest that whatever effects
changing
the setting of a measuring device may have on _individual_ remote
events,
the _statistical distribution_ of such events remains unaltered.
Mermin(6)
concludes as a result that "The manifestation of this 'action at a
distance'
is revealed only through a comparison of the data independently
gathered
at A and at B" (the locations of the two measuring instruments). He
characterises
the measurements carried out at the remote location as being "entirely
random".
But what is "entirely random"? What appears to
be random
in a given situation depends on the context, on what one knows and on
one's
point of view. Coded messages, the roll of a die, output from a
computer,
or the movements of a person operating a piece of machinery may all
appear
random if one does not know the relevant details (the code that is used
in the coded message, the exact manner in which the die is thrown, what
the computer program or piece of machinery is and what it is doing) and
yet if one knows this information many of the details of such phenomena
can be understood. An alternative description of microphysical reality
to that provided by quantum mechanics, if any such exists, may be
associated
with a different kind of statistical average. What seems to be noise
may
no longer be noise, and the theorem implying no manifestations of
interconnectedness
for the statistical average may no longer apply.
But do situations actually exist in nature whose
descriptions
involve less randomness in particular aspects than quantum mechanics
implies?
In the past, it might have been stated unconditionally that von Neumann
had under very general conditions disproved the existence of such a
possibility,
but it is now recognised(13) that the supposed proofs of these
assertions
contained assumptions that are in fact unjustifiable. There exist
arguments(14-17)
that complementary descriptions to those of quantum mechanics can and
in
all probability do occur. Detailed discussion of this issue will play a
central role in the analysis that follows.
4. CAUSAL INTERPRETATIONS OF QUANTUM MECHANICS
In the context of the present problem it is
useful to
think in terms of causal interpretations of quantum mechanics. These
are
models where the observed indeterminacy is a consequence of uncertainty
of the actual state of a system whose dynamical laws in themselves are
completely deterministic. Bohm's causal model(9) involves an ensemble
of
particles distributed in phase space with a particular self-consistent
probability distribution function and moving in accordance with certain
deterministic laws. The statistical predictions of quantum mechanics
are
reproduced exactly in a way that avoids the usual introduction of
unclear
and arbitrary assumptions concerning measurement, wave function
collapse,
or separation of a system into observer and observed. The non-locality
which Bell showed to be implicit in quantum mechanics is _explicit_ in
Bohm's causal model, in that the motion of the particles in the model
is
governed by an interaction, determined by the quantum wave function of
the system, that is non-local.
In most common situations, averaging over the
particle
positions in the causal model makes the mean direct influence of one
particle
on another at large distances negligibly small. This is not so,
however,
in EPR-type situations where the wave function has a
non-decomposability
property which makes this interaction at a distance significantly
different
from zero even at long range(13). But, even in these situations, once
we
take an ensemble average, using the special distribution function in
phase
space that assures the statistical equivalence of the causal
interpretation
and quantum mechanics, we revert to the quantum mechanical prediction
that
statistically no influence at a distance can be demonstrated. One may
ask,
however, why only these special distribution functions should apply. Is
there anything absolute about the ignorance implicit in the use of
these
particular distribution functions? The argument will be made in the
following
that other distribution functions, with different statistical
properties,
are relevant in other contexts, especially those associated with life.
Situations where a change in context leads to
a new kind
of statistical distribution becoming relevant are indeed commonplace
in
science: they occur for example whenever a phase transition occurs that
leads to a breaking of symmetry. As a result of symmetry breaking,
statistical
distributions that are _asymmetric_ with regard to this symmetry may
come
into existence in situations where previously only symmetric
distributions
were observable or relevant. Analogously, it can be anticipated that
special
situations will exist whose natural description involves probability
distributions
other than the particular ones that arise in the _quantum formalism_.
5. MULTIPLE DESCRIPTIONS OF REALITY
We now discuss in some detail this idea that
rather than
a single, universal, description of reality (such as that provided by
quantum
mechanics) being appropriate in all circumstances, more than one
complementary
or alternative form of knowledge may exist(14-17). This state of
affairs
is most simply understood with reference to a special feature of the
quantum
domain related to quantum indeterminism, which we shall characterise as
the _loss of universal determinism_. This latter term is intended to
reflect
the fact that in this domain quantum indeterminism renders impossible
the
making of exact predictions on the basis of a _universal formula_
(which
would be possible in principle in classical physics if the relevant
dynamical
laws such as Maxwell's equations or Newton's laws were known). We
hypothesise
that two alternative strategies are possible for dealing with the loss
of universal determinism. The first, the method of science, is to
retain
conformity with the demands of reproducibility and universality by the
device of replacing the no longer possible strict determinism by
_statistical
determinism_.
The outcome of this approach is quantum
mechanics. The
second, a method that is in general terms favoured by life, involves
renouncing
the demand for universal knowledge in favour of more specialised and
purposeful
adaptations to the more limited class of situations that the organism
or
organisms concerned is liable _naturally_ to encounter in the course of
its life. A human being learns, for example, the language that is
spoken
in his or her own particular environment, rather than language in
general.
These two strategies lead in different
directions. The
strategy of science leads towards the accurate specification of form,
while
that of life leads in the direction of meaning. These two
directions, form
and meaning, are the two components of David Bohm's concept relating to
the universal nature of things, _soma-significance_(18). Meaning is an
aspect of reality tied to the achievement of goals and to specific
context
that is sufficiently subtle and complex as not to be representable by
any
closed formula. Furthermore, the technique of statistical averaging is
especially irrelevant in the context of meaning, since its influence in
general is to transform the _meaningful_ into the_meaningless_. It is
not
useful to consider the meaning of a particular word averaged over all
languages,
and computing the statistics of word order and frequency in a discourse
tells one very little about the meaning of the discourse.
Investigations
into meaning(18,19) are investigations in a different direction to that
in which one is led by scientific investigations into reproducible form.
But science is involved with the accurate
specification
of form, and this enforces the kind of _formal_ specification of nature
characteristic of quantum measurement theory. This contrasts with the
philosophical
informality of classical physics with its naive realism. The perceptual
and interpretative processes of living organisms do not admit of the
formal
specifications demanded by quantum measurement theory. Therefore, as
discussed
in Ref. 17, there is no good reason to identify the class of
experiments
defined according to the precepts of quantum measurement theory with
the
category of all investigable phenomena. Indeed, the quantum formalism
does
not apply in any obvious way to _natural_ situations, situations such
as
those of the phenomena of life that come into being by chance rather
than
by scientific design, and the common belief that it should be possible
in some way to apply quantum mechanics to natural situations just as
readily
as to the controlled experiment is one that seems to owe its existence
to an extrapolation that cannot, under close examination, be justified.
6. RANDOMNESS AND FOCUSSING
These arguments lead us to the conclusion that,
because
of the different kind of perceptual and interpretative processes
characteristic
of life compared with those of science, living organisms can
possess knowledge
that is more detailed in certain aspects than is the knowledge
specified
by the quantum theory. One may talk in terms of higher
discrimination and
selectivity, which improvements can be attributed a different kind of
contact
with nature. By way of analogy, it can be compared to a process that
makes
contact with individual atoms, relative to one that makes contact with
the macroscopic aspects of a system only.
From the point of view of a causal model such as
that
of Bohm's, alternative kinds of probability distribution in phase space
become relevant. In general terms, these distributions can be
characterised
as being highly focussed in relation to the organism's specific goals.
Such focussed behaviour in living organisms is typified by, for
example,
the activities of a tightrope walker, or of a darts player. Efficient
focussing
comes into being naturally over the course of time as the consequence
of
processes of trial and error learning occurring during the
developmental
process. Our assumption in relation to psi functioning is that
here also
the relevant probability distributions are highly focussed in relation
to goals, in a way that may become more effective over time as
development
through learning takes place.
6.1. An Illustration
The kind of focussing process involved can be
illustrated
with a simple example. This consists of a coil attached by a length of
wire to an ammeter a short distance away. The meter needle can be
caused
to deflect by moving a magnet in the vicinity of the coil. A person who
does not understand the facts of magnetism and attempting to produce a
meter deflection in a particular direction will at first move the
magnet
randomly and hence produce deflections in a random direction. But he
may
in time discover the principle that is involved and utilise the magnet
in a non-random way, and gain thus the ability to produce deflections
in
a prescribed direction at will. In exemplification of the processes
discussed
above, his learning process changes an initially random distribution of
magnet movements into one focussed with regard to the goal, the
principles
referred to above. The proposal being made here is essentially that
mechanisms
of a similar kind may be operative at a _microscopic_ level in
biosystems.
7. SPECULATIVE MODELS
In the biological world, evolution through
natural selection
tends to give rise to adaptive elaborations of preexisting phenotypes
(manifest
behaviour). Thus a primitive sensitivity to light becomes elaborated
into
more discriminating sensitivities and ultimately into fully detailed
vision.
In the case of psi one may similarly anticipate the development of
forms
of organisation of the nervous system capable of interacting
non-locally
with other systems. Such organisation has been discussed by C.N.
Villars(20),
who starts with the assumption that in a number of types of situation
encountered
in a quantum mechanical context, including EPR-type situations,
microphysical
objects function as "centres of perception", acting as if sensitive to
non-local information. Villars hypothesises that somewhere within the
nervous
system forms of organisation of microphysical objects exist capable of
amplifying, selecting and combining the perceptions through non-local
connections
of individual microphysical objects, in a way analogous to the way in
which
the ordinary senses function through the working together of many
subunits.
As a result we can have perceptions of distant objects and events
through
the non-local connections in the same kind of way as we acquire
perception
of the more local environment through the ordinary senses. The
scope and
form of such perceptions at a distance would be a function of the
particular
forms of organisation and activity present in these postulated
sense-like
processes. Except for the absence of a theoretical mechanism for
overcoming
the limitations of ordinary quantum descriptions by making use of an
underlying
causal model, Villars' proposals are similar to those advocated here.
Further similar proposals have been made by
Bohm(21)
also, based on his causal interpretation. His conclusion is that while,
in principle, coherent non-local effects of one system upon another are
possible, in practice such connections are "fragile, and easily broken
by almost any disturbance or perturbation", and that they would occur
only
at very low temperatures or under special conditions such as those
pertaining
in the EPR situation. But in the picture advocated here, life has the
ability,
exemplified by the example of the tightrope walker, to learn under
conditions
that are not excessively unfavourable to it to neutralise of compensate
for the effects of external disturbances. Such compensation capacity we
assume to be functionally effective in respect to the "fragility"
referred
to by Bohm also.
A comment by Bohm et al.(9) regarding the
understanding
of superconductivity in the causal interpretation provides a clue as to
what kind of overall organisation might be relevant for psi
functioning.
This situation is described in the following terms:
"In the superconducting state of a many-electron
system,
there is a stable overall organised behaviour, in which the movements
are
coordinated by the quantum potential so that the individual electrons
are
not scattered by obstacles. One can say indeed that in such a state,
the
quantum potential brings about a coordinated movement which can be
thought
of as resembling a 'ballet dance'."
The assumption of a superconducting-like state
provides
an example of a context where different organisms can be highly
correlated.
Such a state may be relevant to the origin of life, or to the Gaia
hypothesis
of Lovelock and Margulis(22). Perturbations such as an increase in
temperature
cause the coordinated organisation to break up, and this would provide
a mechanism by which the amount of linking of an individual organism to
other systems through non-local interconnections could be adjustable.
One
may imagine that life may exist from the beginning (cf. Ref. 22) as a
cooperative
whole directly interconnected at a distance by Bell type non-local
interactions,
following which modifications through the course of evolution cause
organisms
to be interconnected directly with each other and with objects to an
extent
that is adapted to circumstances. One can see conceptual
similarities between
psi skills and ordinary skills, e.g. between the perceptual skills of
hearing
and telepathy on the one hand, and between the forms of control of
matter
involved in the control of the body and in psychokinesis on the other.
From this point of view, it is only in regard to the mode of
interaction
that the ordinary phenomena and the analogous paranormal ones differ
from
each other. These analogies will be discussed in more detail
elsewhere.
The theories discussed here have the feature, in
contrast
to that of quantum mechanics, of being qualitative rather than
quantitative.
This may be an unavoidable correlate of such aspects of nature,
stemming
from a fundamental irreproducibility of biology and of the phenomena
connected
with the indeterminism of the quantum domain.
8. SUMMARY AND CONCLUDING REMARKS
The goal of this paper has been that of gaining
some
understanding, within the framework of conventional science, of
phenomena
such as telepathy and psychokinesis which (particularly in terms of the
actual experience(23,24)) seem to involve some form of direct contact
at
a distance. While the non-local correlations found in EPR-type systems
seem at first sight(20) to provide a scientifically valid basis for
such
direct contact (particularly for the case of telepathy which has many
features
that parallel those of EPR-type correlations), calculations using the
formal
apparatus of quantum theory suggest that any such connections will be
purely
random and thus unusable. But the self-consistent and completely
logical
multiple-description view of knowledge advocated here, an alternative
to
the conventional view that all knowledge may be reduced to quantum
mechanical
knowledge, allows life to have its own potentialities, beyond what the
constraints of "good scientific method" will allow, for knowing and for
acting on the basis of such knowing. Included in these categories of
acting
and knowing are psychic functioning.
The present theory parallels in a number of
respects
the theory of Walker(12) with its postulate that the statistical
outcomes
of quantum phenomena can be modified by consciousness, and the paper of
Stapp(25), in which creative mind has a similar function. These
different
approaches may all be representations of slightly different aspects of
the same underlying truth, gained by taking as a starting point a range
of different points of view.
