Re: art, shape, and symmetry

Dear Jim, (and the other readers),

I knew Mike's book for many years. I enjoyed it very much, it was an excellent work.
I would like to add, that brain research, and especially mapping the localisation of the different brain functions differentiated, and made our picture on it more sophisticated, during the nineties. This concerns much emphasised the role of shapes (right hemisphere) and digitalised information storage (left hemisphere) in our brain data processing, and we hope to learn much more about the collaboration of the two asymmetric hemispheres in a few years. In the latter respect I would remember to the early paper presented by Chua (Berkeley) and Roska (Budapest) at the first Symmetry Congress in 1989, which led them to the discovery of the combined digital-anaolgue chip, the basic unit of the first working electronic neural model: the artificial retina, in 1993. This is a model of the parallel processing of analogue (shape) and digital (the detailed information coded beyond the shape) data, just like human brain does it. Cognitive sciences are in a revolutionary era.

I am working my way through a brilliant book, SYMMETRY, CAUSALITY, AND
MIND.  Michael Leyton.  MIT Press.  1992

I wish it made for smoother reading, but he is intent on establishing
theorems and principles that he can prove so the book plods a bit. However,
his ideas are very useful.

For example, "The meaning of an art-work is the process-history inferred
from it.  The experience of an art-work is the experience of inferring that
history, i.e., the experience of solving its history-recovery problem. "

"There is a primary drive to seek causal explanantion; i.e. a drive
independent of, and not subservient to, any other goal.  In other words,
the history-recovery problem is a primary drive."

"(1) Each individual has a preferred amount of environmental asymmetry, an
amount that the individual seeks, and finds extremely appetitive. (2) As
the amount of environmental asymmetry is raised or lowered from this level,
the environment becomes more and more aversive."

"The Representation-is-Explanation principle states that any cognitive
representation is a causal explanation.  Thus, since aesthetics is the
intrinsic evaluation of causal explanation, aesthetics is the intrinsic
evaluation of cognitive representation.  ...this makes aesthetics
intertwined with the very substance of cognition.  That is,
since,...causality is the content of all cognition, we conclude that
aesthetics is the evaluation of cognitive content. "

A lot here I have skipped but one can get the general idea.

I am attracted to the connection he makes.."an important means by which the
mind recovers the past is by shape. Shape forms the basis for memory. The
mind assignes to any shape a causal history explaining how the shape was
formed. It is by doing this that the mind converts shape into memory."
These are principles that I have always worked with in making paintings,
and tried to express to students of painting.  Here we have a cognitive
psychologist going at the problem of and connecting it to basic cognitive
drives in the species.


greetings to all

Jim
