Thanks for the very interesting video.
Hi Alberto,
I agree. Roger Penrose is one of my favorite theorists.
Concerning Platonia and Contingia, there are much to say if we
introduce natural selection, the only well know creative process.
The world of Platonia, in terms of natural selection, is the peak of
the "fitness landscape" (FT). The FT is the point of perfection from
which the living form, or the living behaviour can not be improved.
Contingia is the world of extinction by random, imprevisible events.
When contingia enters,the most filnely adapted beings perish due to
their specialization, and gives the world to generalists, good in
nothing, bacterias, fungi and " adapted of fortune" that casually are
adapted to the disaster scenario: scavengers, tunnel diggers, shallow
water habitants etc. None of them are beatiful. But extinction gives
a opportunity to new perfect forms that are better than the former. If
there would be no extinction, we would still be bacterias.
A very good point! One of my constant complaints is that the
Selection aspect of evolution is grossly neglected in discussions of it.
This creative destruction appears also in the market, (That is a
controlled darwinian process under State laws). and in general in any
creative process.
Yes, it is the tendency to "select" an outcome from a domain of
many possible outcomes. Mathematically, it resembles a many-to-one
mapping function. Mutation, in evolutionary models, can be seen
mathematically as a one-to-many mapping function. It is interesting to
me that these two mapping functions are the inverse or dual of each
other. I think that this feature can be used to mathematically model
evolution.
The perfect forms inhabit our mind because we have to measure
ourselves against the ideal. Beauty is a measure of closeness to the
ideal. I´m persuaded for example that the beauty of movements of a
dancer is related with the use of energy for a given movement. the
less energy the dancer use, the more beautiful is the movement. And we
perceive this use of energy as smooth and beatiful movement because to
mate or to be a friend of a good user of his energies (by a good
neurocoordination) has been crucial for survial. A good dancer is in
the peak of fitness landscape in energy usage, so he exhibit it. And
Platonia in our mind know it.
There are evolutonary explanations for many others notons of beauty.
As Penrose said the motor of this process of evolution and life is
the gradient of entropy. The photosyntesis is a capture of energy that
requires the building of a chemical (and phisical) infrastructure that
requires information processing, from genes to phenotype building
programs to reproduction and so on. And only in a positive gradient of
entrophy this processing is possible

for living beings.
It might be that "living being" are, as an equivalence class, all
the possible structures that can process gradients of entropy for the
purpose of generated their structure.
