The human mind and psyche - are they one and the same? The word
‘psyche’ is used in a variety of ways. It can be used to mean:
* the soul or spirit ï‚· the subconscious ï‚· the whole of the mind.
The psyche as the soul or spirit I like to believe that there is a soul
or spirit - a part of me that will continue to exist after I have died.
Unfortunately I do not see any evidence of this. Some people claim that
the body losing a tiny fraction of weight after death is evidence of a
soul leaving the body (as popularised in Dan Brown’s novel The Lost
Symboli), but I remember reading an article in New Scientist magazineii
suggesting that this was simply the deoxygenation of the brain. When
trying to defend the idea of a soul, there is often confusion between
experience and conclusion. For example, when I meditate I often achieve a
state in which I have lost recognition of where my body ends and the
external world begins. Some who have had similar experiences talk about a
‘oneness’, or they describe how a spiritual experience has
transcended the physical. Brain scans of people in deep meditation show
that there is decreased activity in part of the cerebellum that allows
us to determine where our body is in relation to the space it occupies.
So, while I would love to claim that my wonderful experience was an
experience of the devine, I think it is more likely to be a divine
experience through a change to the operation of my central nervous
system. Those who have experienced ‘oneness’ would conclude that
there is a soul. I, however, would suggest that while their experience
is real, their conclusion is spurious. Now, I could be wrong, but I will
need more than grand words about the noble human spirit to convince me.
The psyche as the subconscious This use of the word psyche seems to
have arisen out of the study of psychology. I think we all have an
experience of the subconscious, and there are many tests to show it
exists empircally. There is a wonderful book called The Happiness
Hypothesis by Jon Haidt,iii and it is the richest book I have read on
the subject of happiness. It is exceptional. Haidt talks about the
difference between the elephant and the rider, and suggests that our
conscious is the rider and our subconscious is the elephant. The rider
might want to head in a certain direction and often the elephant will
comply. But if the elephant chooses not to comply there seems to be
little the rider can do. Here is an example: We all know that we should
live on less than we earn and save the difference in a compounding
investment. But then we walk past a store and see a book, CD or pair of
shoes we just have to have, and the elephant takes us in. And another: I
know I should eat less and exercise more, but the elephant has me
reaching for the remote control and donuts. By the same token, the
subconscious is an incredibly fast mechanism for processing data at
levels the conscious mind cannot compete with. Malcolm Gladwell talks
about this in his book Blink.iv Unfortunately, our intuition is not
always correct; it is simply fast. So if we want to call the psyche the
subconscious... so be it. The psyche as the whole of the mind There is
now research to suggest that (and I was blown away when I read this) we
do in fact have neurons in and around our stomach.v So when people say
‘I have a gut feeling’ they could be speaking more literally than
they realise. I guess this should come as no surprise, as the brain is a
part of the central nervous system that stretches throughout the body.
There was a theory, a controversial one, by the Princeton University
psychologist Julian Jaynes,vi that suggests our consciousness came about
as we increased the number and quality of connections between the right
and left hemispheres of the brain. Jaynes sights archeological evidence
to suggest that before these connections were complete, people thought
the voices in their heads, which most of us now know we can control,
were the voices of gods. It is interesting to try to imagine what people
will be saying about our level of consciousness in another 50,000
years.
