“The return of the Laws of Form and (some) Perfection in Language"
Chomsky’s Minimalist Program has been criticized by some because it
portraits Narrow Syntax as the perfect solution to the problem of
computing in real time the match between linguistic sound and its
interpretation. The rationale of this criticism is that language is
part of our biology and biology never finds optimal solutions, only
“satisficing” ones, as the result of adaptation and natural selection.
Whether one accepts Minimalism or not on other grounds (I do) it can
be shown that this critique is unfounded. I will review an entire
spectrum of factors that have played a major role in evolution and
that are alien to adaptation and natural selection. For historical
reasons, and for want of a better term, these are called “the laws of
form”. These are constraints explained by mathematical and physico-
chemical laws leading to optimal solutions that exceed the boundaries
of biology and are quite abstract.
When very similar specific morphologies (Fibonacci series and
Fibonacci spirals) are observed in spiral nebulae, in the geometrical
arrangement of magnetically charged droplets in a liquid surface, in
seashells, in the alternation of leaves on the stalks of plant stems
and in the disposition of seeds in a sunflower, it can hardly be that
natural selection is responsible. As we are going to see in some
paradigmatic instances, the relevant search space would be so huge
that the hypothesis of such solutions having been found by blind trial
and error followed by natural selection becomes exceedingly
improbable. It is even hard to suppose that some genetic machinery is
specifically (one has to insist on this: specifically) responsible for
coding these forms as such. It’s vastly more plausible to suppose that
the causes of these forms are to be found in the elaborate self-
organizing interactions between several components that are, indeed,
coded for by genes (protein complexes, morphogenetic gradients, cell-
cell interactions and so on) and chemical and physical forces. The
latter are vastly more ubiquitous and vastly less modular than
biological processes. They transcend the biological subdivisions into
species, genera, families, orders, classes and phyla.
After having cleared the way for optimal solutions in biology in
general, we will examine applications of this model to the
organization of language.
Everyone is welcome.
