The World And
The Mind Relativity
Theory and Quantum Theory said something important about the mind. They were as
much about mind as they were about matter, only in a more subtle way. Relativity
Theory was not only about reality being "relative" to something. It
was (first and foremost) about reality being beyond the reach of our senses. Einstein's underlying principle is that
we don't always see the universe as it is. Newton's underlying principle was that
we see the universe as it is. Newton's Physics is a description of how our mind
perceives the universe. There are bodies, there is absolute time, etc. Einstein's Physics is a "guess"
about what the universe really is, even if our mind cannot perceive it.
Einstein's Physics implied that there may be aspects of the universe that our
mind cannot perceive, and that we can guess only by analyzing the aspects that
we can perceive. Quantum Theory
was not only about reality being "quantized". It was also about
reality being beyond the reach of our mind. The single most distressing finding
of Quantum Theory is that reality, as we know it, only occurs when somebody
observes it. The electron is in a certain place only when somebody actually
looks at it, otherwise the electron is, simultaneously, in several different
places. We can analyze
this finding with either of two stances. According to the first one, our mind
has no limitations. It can perfectly perceive nature as it is. It observes only
one value because that is what nature does: the multiple choices for a
quantity's value collapse to just one value when that quantity is observed by
an observer. According to the
second one, our mind has limitations. The quantum collapse from many values to
just one value is due to a limitation of our mind. Our mind cannot perceive
nature as it is. It can only perceive one value for each quantity. The electron is
in many places, but our mind cannot perceive a thing being in many places at
the same time, so it "collapses" the electron into only one specific
place at a time. This is just an effect due to the limitation of our mind. We
are forced to "sample" reality because we can't handle all of it. After
all, that's what all our senses do. They are bombarded all the time with data
from the environment, and they only pick up some of those data. We don't
perceive every single detail of what is going on around us, we are forced to be
selective. The mind turns out to be a sense that also has limited capacity,
although the limitation is of a different kind. Each item of reality (a
position, a speed, etc) "has" many values. The reason we observe only
one value is that our mind can't handle a universe in which quantities have
more than one value. The conceptual
revolution caused by Quantum Theory was somewhat deeper than the one caused by
Relativity Theory. Reconciling Newton and Einstein is relatively easy: Newton's theory was not
false, it was just a special case of Einstein's theory, the one in which the
spacetime is Euclidean. Reconciling Newton and Quantum Theory is, on the other
hand, impossible: Newton's theory is just false. It seems to work because we
insist on assuming that such things as big objects truly exist. A theory of the
mind that does not take into account Relativity is a legitimate approximation,
just like a theory of the Earth that does not take into account Relativity is a
legitimate approximation. But no theory of the mind can ignore Quantum Theory. Back to the beginning of the chapter "The New Physics" | Back to the index of all chapters |
