Commenting upon Pedro's"

S: This is the position of the biosemiotics community (Semiotiics -
the study of meaning construction). With a nod to Loet, the procedure is
to begin with the most highly developed example of semiosis that we know of
-- human discourse -- to derive the necessary categories (induction, etc.),
which are then generalized in the spirit of systems science, so as to apply
them to biosemiosis, and all the way to pansemiosis if we like.

>3. Metabolic networks, signaling networks, gene networks, degradation
>networks ---make sense overall, and together they provide the molecular
>signature of meaning.
S: Or the molecular machiney for meaning construction.
>4. A very special organization is formed, with formal properties not well
>explained yet, that provides attractors, amplification, robustness,
>resilience, stability, etc. involving the whole cellular system. See the
>contemporary problems of "System Biology" (or those of the old, outdated
>notion of "autopoiesis").
S: The formal properties will necessarily be derived from human
discourse, and imposed upon the cellular system.
>5. When eukaryotic multicellularity emerges, the above (4) becomes an even
>more fascinating set, where some of the mathematical-
>statistical-computational properties, converging in a controlled life
>cycle, become paradoxically more susceptible of formal approaches.
S: Likely because our semiotic categories can more easily be
visualized as being operative here.
>6. Nervous systems adopt the specialized function of putting in
>"electro-molecular" terms the computational task of guiding the whole
>multicellular organism along the implementation of its fitness in an open
>ended environment.
>
>7. Self-reference is an important aspect, both cellular-molecularly and
>also for nervous systems.
And, as Loet has ben telling us, understanding this has been derived
from study of human discourse.
>8. Any social, cultural, individual, neuronal, etc., visions or
>acceptations of meaning finally conduce to life cycles in-the-making and
>confronting an open ended environment.
>
>9. Meaning can only be about life, around the multiple dimensions of fitness.
S: In my (NSH) opinion, meaning can be extended to all dissipative
structures. From an evolutionary viewpoint, nothing comes from nothing.
If we have meaning, it must have a precursor in simpler sysems. After all,
e.g., hot air rising has great meaning to an individual nascent hurricane!
>10. The informational philosophy of the above points could be put in
>congruence with some new information-physics approaches ("generatitivity"
>of the vacuum).
S: A task for pensemiotics!
