This article presents some results of a research on computational strategies for the visualization of sign classification structures and sign processes. The focus of this research is the various classifications of signs described by Peirce. Two models are presented. One of them concerns specifically the 10-fold classification as described in the 1903 Syllabus (MS 540, EP 2: 289–299), while the other deals with the deep structure of Peirce’s various trichotomic classifications. The first is 10cubes, an interactive 3-D model of Peirce’s (...) 10-fold classification, as described in the Syllabus. The second is 3N3, a computer program that builds equivalent diagrams for any n-trichotomic classification of signs. We are specially interested in how a graphic design methodology, associated with computer graphic resources and techniques, can contribute to the construction of interactive models that serve as tools for the investigation of C. S. Peirce’s theory of signs. (shrink)

Peirce's classifications of signs started to be developed in 1865 and it extends up to 1909. I will present on the period that begins in 1865, and that has two moments of intense production - "On a New List of Categories"and "On the Algebra of Logic: a contribution to the philosophy of notation". It is an introductory approach whose intention is to make the reader be familiar with the Peircean complex classifications of signs.

The pragmatist turn in Philosophy in the late XIX century and XX century was a serious attempt to refuse the privilege of the representational elements of the conscious- ness in the production of knowledge. Such privilege has its roots in Ancient Philosophy, in some consequences of the Platonic heritage, but was toughened by Modern philosophers of empiricist or aprioristic lineages within the modern concepts of Experience and Truth. With these last concepts of Experience and Truth I’m referring to the objectivising (...) tendency that leads to identify experience with the final object resulting from the judicative fixation of relations. Due to the fixation of some basic relations the object of experience was identified and conceived with such and such characteristics as something independent of the mental or judicative activity. Such method of fixation and objectivising of relations is also present in the common-sense ideas of Reality, Experience and Truth. In the field of the theory of signs the reputation of the modern concept of representation was so vast that despite the progress in the discovery of the differential character of the linguistic units, Saussure’s well-known notion of sign and the division between “signifiant” and “signifié” still kept the reference to the double across the body/mind polarity and to the “mental image” of the sign, Vorstellung, concept or “signifié,” as the core of meaning. If Peirce and James agree in the refusal of the classical theory of representation, their rejection came from different horizons and their critiques don’t mean the same. I’ll try to show that James’s and Peirce’s attempts are not disjunctive, although they are not members of a simple addition. In the writings of the Tartu School and in T. Sebeok’s reassessment to Peircean semeiosis one finds interesting tools to reconsider the relation to the World of the “field of consciousness” and semeiosic cycles, beyond representationalism, such as the concepts of environment and primary, secondary and tertiary modelling systems. Starting with these insights I’ll propose at the end of the essay the notion of a double environment between psychic systems and systems based on communication. (shrink)

William James (1842-1910) influenced the American intellectual history of the second half of the xix century and the beginning of the xx in various fields, due to his activity as a writer, a teacher and experimentalist. William James was a participant in the germinal, legendary meetings of the “Metaphysical Club,” in 1872, together with C. S. Peirce, Chauncey Wright, O. W. Holmes Jr., and others, in conversations that would lead to the first formulas, close to the future “pragmatism,” regardi...

Attempts to explain Peirce’s various classifications of signs have been a preoccupation of many Peirce scholars. Opinions are mixed about the sense, coherence, and fruitfulness of Peirce’s various versions, particularly the latter ones. I argue here that it is not a fruitful enterprise, even if sense could be made of them. Although Peirce makes his motivations for the classification of the sciences fairly explicit, it’s hard to find Peirce’s reasons for sign classification. More importantly, I try to make the case (...) that such classifications are premised on a reductionist framework of semiosis that is contrary to the irreducible triadic character of signs that Peirce otherwise espouses. The reductionism is the result of Peirce’s use of certain models for his sign classifications, in particular, Mendeleev’s periodic table. I suggest that the remedy for the reductionism is to re-emphasize the processual and functional view of semiosis, rather than to focus on particular classes of signs. Corresponding to the three triadic conditions of semiosis, I argue that signs function to inform, represent or refer, and interpret, and that understanding these three function and how they interrelate may prove to be a more fruitful approach to sign analysis than sign classification.
