Since Peirce defined the first operators for three-valued logic, it is usually assumed that he rejected the principle of bivalence. However, I argue that, because bivalence is a principle, the strategy used by Peirce to defend logical principles can be used to defend bivalence. Construing logic as the study of substitutions of equivalent representations, Peirce showed that some patterns of substitution get realized in the very act of questioning them. While I recognize that we can devise non-classical notations, I argue (...) that, when we make claims about those notations, we inevitably get saddled with bivalent commitments. I present several simple inferences to show this. The argument that results from those examples is ‘pragmatic’, because the inevitability of the principle is revealed in use (not mention); and it is ‘semiotic’, because this revelation happens in the use of signs.

It is commonplace to describe the pragmatist conception of truth as incompatible with correspondence theory. This popular description relies on a deflationary reading of Peirce and James’s many apparent endorsements of correspondence. This reading says they regarded it as a mere platitude or truism, not as a substantive piece of philosophical theorizing. There are two main reasons typically offered in support of this platitude narrative – its consonance with Peirce’s original formulation of PT from 1878, and the objections that pragmatists (...) frequently raised against various notions traditionally associated with CT. I argue that neither reason is compelling and that PT and CT are compatible conceptions of truth. (shrink)

A promising recent approach for understanding complex phenomena is recognition of anticipatory behavior of living organisms and social organizations. The anticipatory, predictive action permits learning, novelty seeking, rich experiential existence. I argue that the established frameworks of anticipation, adaptation or learning imply overly passive roles of anticipatory agents, and that a fictionalist standpoint reflects the core of anticipatory behavior better than representational or future references. Cognizing beings enact not just their models of the world, but own make-believe existential agendas as (...) well. Anticipators embody plausible scripts of living, and effectively assume neo-Kantian or pragmatist perspectives of cognition and action. It is instructive to see that anticipatory behavior is not without mundane or loathsome deficiencies. Appreciation of ferally fictionalist anticipation suggests an equivalence of semiosis and anticipation. (shrink)

Some have suggested that images can be arguments. Images can certainly bolster the acceptability of individual premises. We worry, though, that the static nature of images prevents them from ever playing a genuinely argumentative role. To show this, we call attention to a dilemma. The conclusion of a visual argument will either be explicit or implicit. If a visual argument includes its conclusion, then that conclusion must be demarcated from the premise or otherwise the argument will beg the question. If (...) a visual argument does not include its conclusion, then the premises on display must license that specific conclusion and not its opposite, in accordance with some demonstrable rationale. We show how major examples from the literature fail to escape this dilemma. Drawing inspiration from the graphical logic of C. S. Peirce, we suggest instead that images can be manipulated in a way that overcomes the dilemma. Diagrammatic reasoning can take one stepwise from an initial visual layout to a conclusion—thereby providing a principled rationale that bars opposite conclusions—and the visual inscription of this correct conclusion can come afterward in time—thereby distinguishing the conclusion from the premises. Even though this practical application of Peirce’s logical ideas to informal contexts requires that one make adjustments, we believe it points to a dynamic conception of visual argumentation that will prove more fertile in the long run.

This paper presents an enrichment of the Gabbay–Woods schema of Peirce’s 1903 logical form of abduction with illocutionary acts, drawing from logic for pragmatics and its resources to model justified assertions. It analyses the enriched schema and puts it into the perspective of Peirce’s logic and philosophy.

Neste e no próximo artigo, buscamos articular a visão compreensiva arquitetônica de Peirce a respeito do fenômeno da retórica relacionando sua abordagem em Ideas, Stray or Stolen, about Scientific Writing com seu tratamento na classificação muito negligenciado das ciências práticas. Neste artigo, primeiro, reconstruímos o principal eixo conceitual de Ideas, Stray or Stolen, que é erguido pelos termos ‘arte universal da retórica’, ‘retórica ordinária’, e ‘retórica especulativa’. Na medida em que este eixo nos guia para a classificação dos estudos especiais (...) da retórica que Peirce propõe na seção final de Ideas, Stray or Stolen, a cuidadosa reconstrução deste eixo constitui um dever hermenêutico, a negligência do qual impediria uma compreensão adequada do que Peirce está classificando no fim de sua abordagem mais madura da Retórica Especulativa. Em seguida, procedemos à exposição das raízes aristotélicas da concepção de Peirce da arte universal da retórica e analisamos a relação intrínseca que a semiose retórica tem com o summum bonum como uma de suas formas evolutivas históricas. Se esta interpretação da concepção de retórica do Peirce é adequado, no entanto, devemos esperar que ele nos dê em algum lugar uma descrição da capacidade de evolução da retórica – e portanto, de crescer – antes de tudo. Será a tarefa de um segundo artigo subsequente mostrar que e de que maneira a concepção de Peirce da a retórica como ciência prática e faculdade instintiva enraizado no “instinto gráfico” responde pela sua capacidade para o crescimento.

Purpose. The paper is aimed at studying the specificity of anthropological problematics in pragmatism from the perspective of its ability to be the source of analytic philosophy evolution in the socio-humanitarian direction. Theoretical basis of the research is determined by the works of the representatives of classical pragmatism, neopragmatism, post-pragmatism and analytic pragmatism. Their works give a clear understanding of the important place of anthropological searches in the theory of pragmatism. Originality. On the basis of the analysis of logical, epistemological (...) and metaphysical ideas formulated by representatives of pragmatism, it is proved that pragmatic methodology is anthropocentric. It is established that the ideological and social foundations of pragmatism can be determined as pluralistic ones due to the attention to the human person. It is revealed that theoretical and methodological searches of pragmatism can be effective in the formation of the socio-humanitarian concepts in analytic philosophy through the specification of strategies for the cognition of human existence in such terms as experience or self and the development of practical ways to justify the truth of knowledge. Conclusions. Pragmatists criticized impersonal, formal thinking, which cannot be an effective means of cognition. Thinking has a social basis and is entirely personal. Justifying its dependence on the socio-cultural sphere and the internal intentions of the subject, it is possible to develop an effective logical theory that operates symbols not only at the syntactic or semantic level but also takes into account the pragmatic aspect of language. Anthropological problematics is also important in the theory of knowledge, the core of which is the notion of pragmatic belief, which enables truth and religious beliefs, since the foundation of the theory of truth is determined by the principle of humanism, and the truth is interpreted as a value orientation. Knowing the external world, we find in it the similarity with us – that’s why the metaphysical foundations of being, according to pragmatism, are personified, and the methodology is defined in anthropomorphic terms. Applying it, the study of human existence is specified in the analysis of psychological and socio-cultural dimensions of such concepts as experience or self. Attempts to comprehend the nature of human existence in pragmatism are empirically grounded. Appealing to science, methodological pluralism, the search for socio-cultural background for thinking and suitable linguistic forms of expression of human experience are the achievements of pragmatism, which are the basis for the socio-humanitarian redescription of analytic methodology.

This essay focuses on Charles S. Peirce’s grammar of representation and its relevance for a logical conception of scientific inquiry. Closely relying on Peirce’s writings, one of his important trichotomies of signs will be discussed in particular: that distinguishing between substitutive signs, or “semes”, informational signs, or “phemes”, and persuasive signs, or “delomes”. According to Peirce, these three categories of signs result from an extension of the traditional division between “terms”, “propositions”, and “arguments” to all signs, understood as the foundational (...) elements with and on which the scientific mind operates. It is shown that such an extended view of logic, conceived as a “semiotic”, or general doctrine of signs, is consistent with Peirce’s metaphysical views on truth and reality. Logic-as-semiotic, and its three corresponding branches of stecheotic, critic, and methodeutic, is thus conceived as a requisite normative trivium for the practice of scientific inquiry, whose purpose is to represent reality truthfully. In the end, we aim to remind that Peirce’s semiotic epistemology must necessarily be contextualized within the frame of his comprehensive philosophy of the scientific “settlement of opinion”.

Peirce wrote in late 1901 a text on formal logic using a special Dragon-Head and Dragon-Tail notation in order to express the relation of logical consequence and its properties. These texts have not been referred to in the literature before. We provide a complete reconstruction and transcription of these previously unpublished sets of manuscript sheets and analyse their main content. In the reconstructed text, Peirce is seen to outline both a general theory of deduction and a general theory of consequence (...) relation. The two are the cornerstones of modern logic and have played a crucial role in its development. From the wider perspective, Peirce is led to these theories by three important generalizations: propositions to all signs, truth to scriptibility, and derivation to transformability. We provide an exposition of such proposed semiotic foundation for logical constants and point out a couple of further innovations in this rare text, including the sheet of assertion, correction as a dual of deduction and the nature of conditionals as variably strict conditionals.

If we accept certain Peircean commitments, Gettier’s two cases are not cases of justified true belief because the beliefs are not true. On the Peircean view, propositions are sign substitutes, or “representamens.” In typical cases of thought about the world, propositions represent facts. In each of Gettier’s examples, we have a case in which a person S believes some proposition p, there is some fact F* such that were p to represent F* to S then p would be true, and (...) yet p does not represent F* to S but some other fact F of which p is false. Since truth is a property of propositions with respect to their representational function, it follows that the belief is not true. Although an examination of Gettier’s two cases, this essay is not a defense of the justified true belief analysis of knowledge, for there are objections to the JTB analysis other than Gettier’s two cases. Rather, Gettier’s two cases are of particular interest for the light they shed on the nature of truth and representation. (shrink)

Peirce seems to maintain two incompatible theses: that a sentence is multiply analyzable into subject and predicate, and that a sentence is uniquely analyzable as a combination of rhemata of first intention and rhemata of second intention. In this paper it is argued that the incompatibility disappears as soon as we distinguish, following Dummett’s work on Frege, two distinct notions of analysis: ‘analysis’ proper, whose purpose is to display the manner in which the sense of a sentence is determined by (...) the senses of its constituent parts, and ‘decomposition’, which is the process of dividing a sentence into a predicate and a subject, and whose purpose is to both to explain how quantified sentences are constructed and to evidence a pattern within a sentence which it shares with other sentences.

Journal Name: Semiotica Issue: Ahead of print.

The article demonstrates how Charles Sanders Peirce built cosmological ideas based on the analysis of the specifics of a human being. It is proved that the possibility of a certain degree of anthropocentrism in Peirce’s cosmological conception was laid down in the categorical system, including the level of the Firstness, Secondness, and Thirdness. It is shown why according to his scientific metaphysics, for everyone, the concept that corresponds to human nature is more true than other ones, as well as why (...) a person instinctively feels the truth. This situation is possible because the laws of thought are formulated in accordance with the laws of nature. Human nature reflects what is in the world. Thus, through self-knowledge, a person also discovers reality itself as a dynamic universe in which the physical and he mental, the real and the ideal are subject to the same laws. However, human beings do not know all of them, but only those that correspond to the level of their understanding and interests. Subsequently, science and technology are built on the basis of individuals’ own intentions. Human beings realize that the universe is boundless and not everything they are able to understand and justify. This makes fallibilism inevitable. It is analyzed how to solve the difficulties of fallibilism; Peirce proposed to use the concept of practical certainty as a basic criterion for recognizing the system of knowledge about the world as true. It is shown that the concepts of tychism, synechism, and agapism, which reveal the meaning of Peirce’s cosmological theory of evolution, are also based on the principles of anthropocentrism and anthropomorphism. Thus, it is argued that human being becomes the key to understanding Peirce’s metaphysical cosmology. (shrink)
