The Organization of Nature:
Semiotic Agents as Intermediaries between Digital and Analog Informational Spaces
This paper offers an ontological perspective to the notion of Form and explores the organization of nature in terms of processes of energy transfer and encoding that lead to the creation of information records. It is proposed that form accounts for the basic unity of information processing, inasmuch as it possesses a triadic nature that includes both the digital and analog components of information plus the intrinsic activity of their conversion process. Form expresses the indissoluble semiosis of processes and structures, and provides an interpretation of the mapping of the space of digitally encoded information into the space of analog information. This relationship in natural systems is made possible by ‘work-actions’ executed by semiotic agents. A discussion inspired by these relations of informational spaces is employed to illustrate how Peirce's categories that converge in the notion of form provide conceptual tools for understanding the hierarchical organization of nature. These informational spaces find their most outstanding example in the study of sequence and structure correlations in RNA and proteins. The mapping between sequence and shape spaces also shows the current need to expand the central dogma of molecular biology.
