“Probably Peirce’s best-known works are the first two articles in a series of six that originally were collectively entitled Illustrations of the Logic of Science and published in Popular Science Monthly from November 1877 through August 1878. The first is entitled ‘The Fixation of Belief’ and the second is entitled ‘How to Make Our Ideas Clear.’ In the first of these papers Peirce defended, in a manner consistent with not accepting naive realism, the superiority of the scientific method (...) over other methods of overcoming doubt and ‘fixing belief.’” — Robert Burch, “Charles Sanders Peirce,” entry in the Stanford Encyclopedia of Philosophy (2021 revision) -/- “Pragmatist epistemologies often explore how we can carry out inquiries in a self-controlled and fruitful way. (Where much analytic epistemology centres around the concept of knowledge, considered as an idealised end-point of human thought, pragmatist epistemology centres around the concept of inquiry, considered as the process of knowledge-seeking and how we can improve it.) So pragmatists often provide rich accounts of the capacities or virtues that we must possess in order to inquire well, and the rules or guiding principles that we should adopt. A canonical account is Peirce’s classic early paper ‘The Fixation of Belief‘. Here Peirce states that inquiry is a struggle to replace doubt with “settled belief“, and that the only method of inquiry that can make sense of the fact that at least some of us are disturbed by inconsistent beliefs, and will subsequently reflect upon which methods of fixing belief are correct is the Method of Science, which draws on the Pragmatic Maxim described above. This contrasts with three other methods of fixing belief: i) refusing to consider evidence contrary to one’s favored beliefs (the Method of Tenacity), ii) accepting an institution’s dictates (the Method of Authority), iii) developing the most rationally coherent or elegant-seeming belief-set (the A Priori Method).“ — Catherine Legg, “Pragmatism,” entry in the Stanford Encyclopedia of Philosophy (2021 revision).

Peirce is best known as the founder of pragmatism, but his dissatisfaction with how others understood and appropriated it prompted him to rename his own doctrine “pragmaticism” and to compose several variants of his original maxim defining it, as well as numerous restatements and elaborations. This paper presents an extensive selection of such formulations, followed by analysis and commentary demonstrating that for Peirce the ultimate meaning of an intellectual concept is properly expressed as a conditional proposition about the (...) deliberate, self-controlled conduct of its interpreters, not the law-governed behavior of its object.

C.S. Peirce held what is nowadays called a “commitment view” of assertion. According to this type of view, assertion is a kind of act that is determined by its “normative effects”: by asserting a proposition one undertakes certain commitments, typically to be able to provide reason to believe what one is asserting, or, in Peirce’s words, one “takes responsibility” for the truth of the proposition one asserts. Despite being an early adopter of the view, if Peirce’s commitment (...) view of assertion is mentioned at all in contemporary discussions it is only in passing. His view is, however, far more complex and nuanced than he has been given credit for. My primary goal here, then, is to get a better understanding of Peirce’s version of a commitment view of assertion. I also argue that figuring out the details of Peirce’s theory of assertion can also provide us with a viable way to respond to problems that contemporary commitment views of assertion face. (shrink)

A comprehensive account of Peirce's third branch of semiotic--universal or speculative rhetoric. The article places Peirce's work in the context of the rhetorical tradition. Unlike the direction that analytic and positivist philosophy took, Peirce does not separate logic and rhetoric. Instead Peirce uses his novel theory of rhetoric to show how logic and scientific investigation is tied to a cooperative community of inquiry.

Although Peirce frequently insisted that continuity was a core component of his philosophical thought, his conception of it evolved considerably during his lifetime, culminating in a theory grounded primarily in topical geometry. Two manuscripts, one of which has never before been published, reveal that his formulation of this approach was both earlier and more thorough than most scholars seem to have realized. Combining these and other relevant texts with the better-known passages highlights a key ontological distinction: a collection is (...) bottom-up, such that the parts are real and the whole is an ens rationis, while a continuum is top-down, such that the whole is real and the parts are entia rationis. Accordingly, five properties are jointly necessary and sufficient for Peirce’s topical continuum: rationality, divisibility, homogeneity, contiguity, and inexhaustibility. (shrink)

In this paper I examine parallels between C.S. Peirce's most mature account of signs and contemporary philosophy of language. I do this by first introducing a summary of Peirce's final account of Signs. I then use that account of signs to reconstruct Peircian answers to two puzzles of reference: The Problem of Cognitive Significance, or Frege's Puzzle; and The Same-Saying Phenomenon for Indexicals. Finally, a comparison of these Peircian answers with both Fregean and Direct Referentialist approaches to the (...) puzzles highlights interesting parallels and important differences between Peirce's final account of signs, and the concepts used in analytic philosophy of language.

Robert Brandom holds that what we mean is best understood in terms of what inferences we are prepared to defend, and that such a defence is best understood in terms of rule-governed social interactions. This manages to explain quite a lot. However, for those who think that there is more to making correct/incorrect inferences than obeying/breaking accepted rules, Brandom’s account fails to adequately capture what it means to reason properly. Thus, in an effort to sketch an alternative that does not (...) rely primarily on peer pressure, I draw on the work of C. S. Peirce. Peirce argued that, when we reason, we manipulate abstract diagrams in order to observe what results. Since some manipulations are barred by the self-same nature of the diagrams, I try to show that this qualitative incompatibility, which I dub “contrapiction,” is a good reason to regard some reasoning as bad.

This entry explores Charles Peirce's account of truth in terms of the end or ‘limit’ of inquiry. This account is distinct from – and arguably more objectivist than – views of truth found in other pragmatists such as James and Rorty. The roots of the account in mathematical concepts is explored, and it is defended from objections that it is (i) incoherent, (ii) in its faith in convergence, too realist and (iii) in its ‘internal realism’, not realist enough.

Early artificial intelligence research was dominated by intellectualist assumptions, producing explicit representation of facts and rules in “good old-fashioned AI”. After this approach foundered, emphasis shifted to deep learning in neural networks, leading to the creation of Large Language Models which have shown remarkable capacity to automatically generate intelligible texts. This new phase of AI is already producing profound social consequences which invite philosophical reflection. This paper argues that Charles Peirce’s philosophy throws valuable light on genAI’s capabilities first with (...) regard to meaning, then knowledge and truth. Firstly, I explore how Peirce’s icon/index/symbol distinction illuminates the functioning of genAI. I argue that genAI’s engineers have skilfully captured a form of symbolicity, but no other sign-kind. In lacking indexical signs, LLMs lack connection with, and accountability to, particular worldly objects. In lacking iconic signs, LLMs are insufficiently disciplined by structural – most notably logical – relationships. Then I argue that GenAI’s astounding stream of articulate, truth-semblant, yet worthless texts issues a timely reckoning to modern philosophy’s representational realism. By contrast, Peirce’s pragmatism scaffolds a rich relational realism (Gili and Maddalena 2022), which shows how meaningful concepts, and a grasp of truth, can only occur across multiple cognitive systems who are simultaneously richly related with one another, and a shared environment in which they continually act and receive feedback, within a logical space of reasons. As Peirce himself noted, “Mere knowledge, though it be systematized, may be a dead memory; while by science we all habitually mean a living and growing body of truth”. (shrink)

Wittgenstein's paradoxical theses that unproved propositions are meaningless, proofs form new concepts and rules, and contradictions are of limited concern, led to a variety of interpretations, most of them centered on rule-following skepticism. We argue, with the help of C. S. Peirce's distinction between corollarial and theorematic proofs, that his intuitions are better explained by resistance to what we call conceptual omniscience, treating meaning as fixed content specified in advance. We interpret the distinction in the context of modern epistemic (...) logic and semantic information theory, and show how removing conceptual omniscience helps resolve Wittgenstein's paradoxes and explain the puzzle of deduction, its ability to generate new knowledge and meaning. (shrink)

In addition to being a founder of American pragmatism, Charles Sanders Peirce was a scientist and an empiricist. A core aspect of his thoroughgoing empiricism was a mindset that treats all attitudes as revisable. His fallibilism seems to require us to constantly seek out new information, and to not be content holding any beliefs uncritically. At the same time, Peirce often states that common sense has an important role to play in both scientific and vital inquiry, and that (...) there cannot be any “direct profit in going behind common sense.” Our question is the following: alongside a scientific mindset and a commitment to the method of inquiry, where does common sense fit in? Peirce does at times directly address common sense; however, those explicit engagements are relatively infrequent. In this paper, we argue that getting a firm grip on the role of common sense in Peirce’s philosophy requires a three-pronged investigation, targeting his treatment of common sense alongside his more numerous remarks on intuition and instinct. By excavating and developing Peirce’s concepts of instinct and intuition, we show that his respect for common sense coheres with his insistence on the methodological superiority of inquiry. We conclude that Peirce shows us the way to a distinctive epistemic position balancing fallibilism and anti-scepticism, a pragmatist common sense position of considerable interest for contemporary epistemology given current interest in the relation of intuition and reason.

Fourteen philosophers share their experience teaching Peirce to undergraduates in a variety of settings and a variety of courses. The latter include introductory philosophy courses as well as upper-level courses in American philosophy, philosophy of religion, logic, philosophy of science, medieval philosophy, semiotics, metaphysics, etc., and even an upper-level course devoted entirely to Peirce. The project originates in a session devoted to teaching Peirce held at the 2007 annual meeting of the Society for the Advancement of American (...) Philosophy.

In his theory of determination, Charles Peirce considered two processes of determination, the semiotic process and epistemology. The semiotic process is an extensional process from object to interpretant that consists of an infinite chain of references that can be spatially reversible. The epistemological process of determination is temporal and irreversible, where the idea grows into the individual mind, as the universe is unfolded by the agency of mind.

This paper seeks an explanation for the challenges faced by Semantic Web developers in achieving their vision, compared to the staggering near-instantaneous success of the World Wide Web. To this end it contrasts two broad philosophical understandings of meaning and argues that the choice between them carries real consequences for how developers attempt to engineer the Semantic Web. The first is Rene Descartes' “private,” static account of meaning (arguably dominant for the last four-hundred years in Western thought), which understands the (...) meanings of signs as whatever their producers intend them to mean. The second is Charles Peirce's still relatively unknown “public,” evolutionary account of meaning, according to which the meaning of signs just is the way they are interpreted and used to produce further signs. It is argued that only the latter approach can avoid the unmanageable attempts to “preprocess” interpretation of signs on the Web that have dogged the project in its many stages, and thereby do justice to the scale, rapid changeability, and exciting possibilities of online information today.

In Spain, Peirce's thought has generally remained almost unknown throughout the syllabi of the various Licentiate programs offered. The only exceptions are the degrees of Linguistic, Communication Studies, and Philosophy, in which Peirce's semiotics is normally only alluded to or cursorily presented. Much the same could be said of Latin America. There is evidence, however, that this situation is beginning to change: translations into Spanish are now appearing, particularly in the web, which make a notable amount of (...) class='Hi'>Peirce’s vast production accessible to the Spanish-speaking readership. Interest in Peirce's work is clearly growing in the Hispanic world, probably due to the general resurgence of pragmatism, and to the gradual approximation of Hispanic philosophers to American academic philosophy.

This chapter analyzes two short texts in which Peirce sketches out an anti-skeptical argument inspired by Kant’s refutation of idealism. The chapter will first consider why Peirce found Kant’s argument interesting and promising, given that it is often regarded as problematic and unsuccessful. It will then briefly reconstruct Kant’s refutation, highlighting its most problematic passages. Moreover, since Peirce’s own version of the argument relies on Kant’s views regarding the temporal structure of consciousness, the chapter will explain how (...) Peirce tackles this issue in “The Law of Mind.” Finally, the chapter considers Peirce’s own anti-skeptical argument and examines whether and how it can be seen as appropriating Kant’s strategy.

The great American philosopher, Charles Peirce, calls his pragmatism a continuation of Jesus' teaching, "Ye may know them by their fruit," and labels his cosmology a doctrine of "Christian Love." Nonetheless, I have found Peirce's understanding of Christianity to be surprisingly unpragmatic. Peirce's pragmatism itself displays an unpragmatic side and the tension between his pragmatic and unpragmatic tendencies reappears in his philosophic theology. I am not certain what a consistently pragmatic Christian theology would look like, but I (...) know pragmatism is the rule rather than the exception in rabbinic Judaism, that is the classical, post-Biblical Judaism of the Talmud. In this paper, therefore, I evaluate Peirce's pragmatism and his Christian theology from the perspective of the rabbis. (shrink)

In this paper, I try to make sense of some puzzling claims that Peirce makes in the Cambridge conferences lectures. I identify four tasks that a successful interpretation of those claims must accomplish. First, we must provide a plausible reading of the “no belief in science” thesis. Second, we must provide a compelling interpretation of the “no science in vital matters” thesis. Third, we must explain Peirce’s distinction between two forms of holding for true. Fourth, we should be (...) able to solve the conflict with “The fixation of belief.” I start by analysing Christopher Hookway’s reading of Peirce’s claims because he clearly identifies these tasks and offers an interpretation with considerable merits. However, I identify a problem in Hookway’s reading, since he fails to account for a normative dimension of the “no science in vital matters” thesis. Finally, I sketch my attempt to accomplish these four tasks while also avoiding this latter problem. (shrink)

The fundamental problem for theoretical aesthetics is its inability to account for art’s meaning-value (Trimarchi, 2022). As previously argued, Art’s higher meaning is only found emerging from the artwork’s tacit dimensions, where empirical-historical intentionality is almost completely inconsequential (Trimarchi, 2024b). The latter’s interpretable ‘phenomenology of sequence’ produces a false theorising tendency, disconnecting art from the history of ideas and severing aesthetics from ethics and logic. Art appears ‘infinitely interpretable’, hence entirely subjective. Adapting Arnold’s (2011) actantial processual approach, I show how (...) Peircian semiotics, via ‘real Secondness’, uncovers art’s higher meaning. Peirce’s ‘diagrammatic thinking’ exposes art’s unique role of ‘objectifying’ the Person (in any subject, via appropriate propositions), without de-valuing this bearer of moral values. His ‘semiotic realism’ helps unveil Scheler’s anthropological (also termed ‘ethical’) phenomenology emerging from Merleau-Ponty’s ‘obscure zone’, to discern poetic from other speculation. Art’s ‘subject-objectivation’ (or, ethical intentionality) is thus able to be mapped phenomenologically to reveal any artwork’s meaning-value orientation. This paper combines Peirce’s ‘phenomenology of reason’ with Scheler’s hierarchy of values and Schelling’s ‘mythological categories’ (Trimarchi 2024b) to suggest a methodology for moving beyond neo-Kantian theoretical aesthetics (and analytical philosophy’s grip on the anti-art of ‘modernity’). That is, moving from the realm of perception to knowing, reviving art’s ontological connection to normative aesthetics. In conclusion, Peirce’s ‘science of ideals’ is thus revealed as Complexity Science, which – via his ‘suspended second’ (or, Ricoeur’s ‘second ontology’) - vindicates Schelling’s claim for how ‘aesthetics becomes objective’ (Trimarchi, 2024a).

This entry is a presentation of C. S. Peirce and of his connections with A. N. Whitehead. Also Whitehead's connections with Peirce are explored.

Although the index is one of the best known features of Peirce's theory of signs there is little appreciation of Peirce's theory of the index amongst contemporary philosophers of language. Amongst Peirce scholars, the value placed on Peirce's account is greater, but is largely based on Thomas Goudge's paper, "Peirce's Index" (Goudge, 1965). Despite marking a crucial milestone in our comprehension of Peirce's theory, our understanding of indices and indexical reference has grown markedly over (...) the last forty years. Time has now come, then, to develop the work that Goudge began and to provide a full analysis of Peirce's account that makes its value to the philosophy of language clear. I undertake this enterprise here. (shrink)

In a world of ever growing specialization, the issue of complexity attracts a good amount of attention from cross-disciplinary points of view as this Congress provides evidence. Charles S. Peirce's thought may help us not only to shoulder once again philosophical responsibility which has been largely abdicated by much of 20th century philosophy, but also to tackle some of the most stubborn contemporary problems. The founder of pragmatism identified one century ago most of these problems, and he also mapped (...) out some paths that we could follow to overcome the poverty of contemporary scientistic reductionism. One of these paths is related with the issue of complexity, that lies at the heart of all his conception. -/- Along this line, the aim of my paper is to describe what Peirce can teach about complexity to semioticians coming from very different scientific backgrounds. The lecture will be divided in three sections: 1) a presentation of Peirce, stressing his personal authority as a scientist philosopher, providing also some biographical details; 2) the theory of categories as the heart of complexity according to Peirce and, finally, 3) some consequences of Peirce's notion of complexity in relation with abduction and creativity, semiosis, cross-disciplinarity and communication. -/- .

The aim of this paper is to describe the situation of mutual ignorance between American and Hispanic philosophical traditions, paying special attention to the figure and thought of the founder of pragmatism, Charles S. Peirce (1839-1914). In order to do this, first of all I will justify the usage of the expression "Hispanic Philosophy", highlighting its heuristic and practical value. Secondly, I will discuss some of Peirce's comments in relation with the Hispanic world. And finally, by way of (...) conclusion, I will mention some of the connections that lie nearly hidden under the cloak of ignorance which divides the two traditions. (shrink)

Questions regarding the nature and acquisition of mathematical knowledge are perhaps as old as mathematical thinking itself, while fundamental issues of mathematical ontology and epistemology have direct bearing on mathematical cognition. Several original contributions to logic and mathematics made by the American polymath, Charles Sanders Peirce, are of direct relevance to these fundamental issues. This chapter explores scientific reasoning as it relates to abduction, a name that Peirce coined for educated “guessing” of hypotheses, which he took to be (...) “the first step of scientific reasoning” and the only creative one. Yet he also argued that all deductive reasoning is mathematical and that all mathematical reasoning is diagrammatic. Representation, especially in the form of a diagrammatic system of logic that Peirce developed, is explored here along with his logic of inquiry, most notably in terms of its manifestation as the logic of ingenuity. Originating in the field of engineering, here the diagram of a problem serves as a heuristic substitute for evaluating the actual situation, an approach that can be extended to other forms of practical reasoning such as ethical deliberation. This chapter also touches upon such diverse but related subjects as non-Euclidean geometry and nonclassical logic, with additional examples that help to elucidate cognitive elements of mathematical knowledge.

Whereas Charles Peirce’s pragmatist account of truth has been much discussed, his theory of perception still offers a rich mine of insights. Peirce presented a ‘two-ply’ view of perception, which combines an entirely precognitive ‘percept’ with a ‘perceptual judgment’ that is located in the space of reasons. Having previously argued that Peirce outdoes Robert Brandom in achieving a hyper-inferentialism (“Making it Explicit and Clear”, APQ, 2008), I now wish to examine his philosophy in the light of inferentialism’s (...) ‘original fount’ – Wilfrid Sellars. Does Peirce’s percept commit him to the Myth of the Given? I argue that it does not, because although the percept is understood as nonepistemic, it is not understood to justify the perceptual judgment. Rather, the perceptual judgement indexes the percept. I explain this original view, then argue that Peirce and Sellars actually have a great deal in common in their rare diachronically mediated yet at the same time direct perceptual realism, and the ‘critical commonsensist’ epistemology to which it gives rise.

People are often interested in physics due to its purported objectivity. It aims to truly be a study of nature (φύσεις) in itself. On the other hand, physics is a human construct, a language we use to describe the world as we experience it. In our quest for absolute reality, then, it seems that we must rid our description of the world of all subjectivity. This lecture concerns part of a story of such an attempt: the quest for absolute measurement. (...) We will consider physical and philosophical aspects of the attempts of Maxwell, Peirce, and Planck to rid our language of physical measurement of undue subjectivity. This will shed some light on the possibility of knowing absolute reality—and the possibility of communication with aliens. (shrink)

One usually makes assertions by means of uttering indicative sentences like “It is raining”. However, not every utterance of an indicative sentence is an assertion. For example, in uttering “I will be back tomorrow”, one might be making a promise. What is to make an assertion? C.S. Peirce held the view that “to assert a proposition is to make oneself responsible for its truth” (CP 5.543). In this thesis, I interpret Peirce’s view of assertion and I evaluate (...) class='Hi'>Peirce’s reasons for holding it. I begin by reconstructing and assessing Peirce’s case for such view as it appears in (EP 2.140, 1903), (EP 2.312-313, 1904), and (CP 5.546, 1908). Then, I continue by elaborating on three aspects of Peirce’s view of assertion, namely, assertion as an act involving a certain kind of responsibility, the proposition as what is asserted, and responsibility for truth as a responsibility to give reasons. With respect to these three aspects, I argue for the following claims: (1) Peirce construed the responsibility involved in asserting as a moral responsibility; (2) Peirce held that propositions are types; and (3) Peirce was committed to a dialogical interpretation of “responsibility to give reasons”. Finally, I end by presenting two objections to Peirce’s view of assertion and its corresponding replies. I conclude that Peirce’s account of assertion is a valuable contribution to the philosophical debate on assertion. (shrink)

Two different versions of the ending of the first additament to C. S. Peirce's 1908 article, "A Neglected Argument for the Reality of God," appear in the Collected Papers but were omitted from The Essential Peirce. In one, he linked the hypothesis of God's Reality to his entire theory of logic as semeiotic, claiming that proving the latter would also prove the former. In the other, he offered a final outline of his cosmology, in which the Reality of (...) God as Ens necessarium is indispensable to both the origin and order of our existing universe of Signs. Exploring these passages, as well as the unpublished manuscript drafts of the article, provides important insights into the key concepts of instinct and continuity within Peirce's comprehensive system of thought.

Peirce is far too strange for the uses to which he is put in art history. This is a plea to art historians for a moratorium on Peirce citations.

There are two ways that we might respond to the underdetermination of theory by data. One response, which we can call the agnostic response, is to suspend judgment: "Where scientific standards cannot guide us, we should believe nothing". Another response, which we can call the fideist response, is to believe whatever we would like to believe: "If science cannot speak to the question, then we may believe anything without science ever contradicting us". C.S. Peirce recognized these options and suggested (...) evading the dilemma. It is a Logical Maxim, he suggests, that there could be no genuine underdetermination. This is no longer a viable option in the wake of developments in modern physics, so we must face the dilemma head on. The agnostic and fideist responses to underdetermination represent fundamentally different epistemic viewpoints. Nevertheless, the choice between them is not an unresolvable struggle between incommensurable worldviews. There are legitimate considerations tugging in each direction. Given the balance of these considerations, there should be a modest presumption of agnosticism. This may conflict with Peirce's Logical Maxim, but it preserves all that we can preserve of the Peircean motivation. (shrink)

In ‘‘Why brains matter: an integrational perspective on The Symbolic Species’’ Cowley (2002) [Language Sciences 24, 73–95] suggests that Deacon pictures brains as being able to process words qua tokens, which he identifies as the theory’s Achilles’ heel. He goes on to argue that Deacon’s thesis on the co-evolution of language and mind would benefit from an integrational approach. This paper argues that Cowley’s criticism relies on an invalid understanding of Deacon’s use the concept of ‘‘symbolic reference’’, which he appropriates (...) from Peirce’s semiotic. Peirce’s analysis as well as Deacon’s appropriation will be examined in detail. Consequently it will be argued that an integrationist reading would add very little to Deacon’s core thesis. (shrink)

Isaac Levi targets an implicit tension in C.S. Peirce’s epistemology, one that exists between the need to always be open-minded and aware of our propensity to make mistakes so that we do not “block the road of inquiry,” and the need to treat certain beliefs as infallible and to doubt only in a genuine way so that inquiry can proceed in the first place. Attempts at alleviating this tension have typically involved interpreting Peirce as ascribing different normative standards (...) to different areas of inquiry. I argue here that such “double-standard” interpretations face significant problems. I offer instead an interpretation of Peirce on which the differences between different areas of inquiry are descriptive rather than normative. Such a view resolves Levi’s tension while interpreting Peirce as consistently subscribing to one normative standard for all inquiry. (shrink)

This paper is a contribution to the long-standing debate over the coherence of Charles Sanders Peirce’s overall system of philosophy. It approaches that issue through the lens of a contemporary debate over the notion of metaphysical grounding, or more broadly, the nature of metaphysical explanation, employing the laws of logic as a case study. The central question concerns how we can take seriously what we shall call Peirce’s Rule—that nothing can be admitted to be absolutely inexplicable—without being vulnerable (...) to a vicious regress or equally vicious circularity. I first argue that in Peirce’s early work he offers a quietist conception of grounding that provides a persuasive and ground-breaking answer to this central question. I then raise a familiar concern, that in Peirce’s later work we find hints of a more metaphysical conception of grounding that seems unable to answer that question and is thus inconsistent with his earlier work. The paper ends with a speculative interpretation of Peirce’s approach to metaphysics and its possible role in grounding logical principles. (shrink)

Necessity is a touchstone issue in the thought of Charles Peirce, not least because his pragmatist account of meaning relies upon modal terms. We here offer an overview of Peirce’s highly original and multi-faceted take on the matter. We begin by considering how a self-avowed pragmatist and fallibilist can even talk about necessary truth. We then outline the source of Peirce’s theory of representation in his three categories of Firstness, Secondness and Thirdness, (monadic, dyadic and triadic relations). (...) These have modal purport insofar as the first category corresponds to possibility, the second to mechanical necessity and the third to a kind of semantic or intentional necessity. We then turn to Peirce’s explicit modal epistemology and show how it began as information-relative, with different modalities (e.g. logical, physical, practical) distinguished in terms of respective ‘designated states of information’, and shifted later in his life towards a more robust realism founded in direct perception of ideas in their relations. We then turn to Peirce’s formal logic, focusing on his diagrammatic system of Existential Graphs where he did his most serious logical research. Finally we discuss Peirce’s modal metaphysics and its implications for determinism and realism about universals. (shrink)

Charles Sanders Peirce has commonly been interpreted as a proponent of an epistemic theory of truth. Such a theory has the apparent advantage of directly undercutting radical skepticism, but the disadvantage of implausibly entailing that there are no truths concerning irretrievably lost facts. Recently Andrew Howat has defended Peirce’s epistemic constraint on truth by recasting Peirce’s claim that all truths would be believed following sufficient inquiry, not as constitutive of truth, but as a Wittgensteinian hinge proposition. I (...) begin with a twofold historical reply to Howat: first, Peirce can at least plausibly be read as claiming that the claim in question is analytic of the concept ; and second, while Peirce did think we must accept without evidence the further claim that there are any truths (so characterized), he regarded this further claim not as a Wittgensteinian hinge but as a reasonable hope. I then substantively defend the latter Peircean proposal, arguing that hopes, as against beliefs, are chiefly warranted pragmatically, and so can be warranted even to a sufficient level to render them properly action-guiding in cases where belief in the same proposition would remain unjustified. I conclude by suggesting, first, that this proposal is superior to Wittgenstein’s own epistemology in evading psychologism, and second, that it attractively vindicates the reasonableness of inquiry on Peircean grounds that don’t require an appeal to an implausible epistemic theory of truth.

This article is a bibliographical entry in the Lexicon Grammaticorum: A Bio-Bibliographical Companion to the History of Linguistics.

C. S. Peirce introduced the term “icon” for sign-vehicles that signify their objects in virtue of some shared quality. This qualitative kinship, however, threatens to collapse the relata of the sign into one and the same thing. Accordingly, the late medieval philosopher of signs John Poinsot held that, “no matter how perfect, a concept [...] always retains a distinction, therefore, between the thing signified and itself signifying.” Poinsot is touted by his present-day advocates as a realist, but I believe (...) that, judged by realist standards, his requirement of minimal dissimilarity backfires. Poinsot thinks that, in analyzing the sign, we should stop before a full merger between sign-vehicle and object is reached. Peirce, by contrast, saw good reason to push the analysis all the way down to one isolated quality. Because such a qualitative merger can lend support to realism, I favour Peirce’s stance. (shrink)

An aspect of Peirce’s thought that may still be underappreciated is his resistance to what Levi calls _pedigree epistemology_, to the idea that a central focus in epistemology should be the justification of current beliefs. Somewhat more widely appreciated is his rejection of the subjective view of probability. We argue that Peirce’s criticisms of subjectivism, to the extent they grant such a conception of probability is viable at all, revert back to pedigree epistemology. A thoroughgoing rejection of pedigree (...) in the context of probabilistic epistemology, however, _does_ challenge prominent subjectivist responses to the problem of the priors. (shrink)

By definition, “logic of postmodernism" would appear to be a contradiction in terms: philosophic post¬modernism emerged as a critique of attempts to found philosophy on some principle of reasoning and to found reasoning on some formal guidelines for how we ought to think. Nonetheless, there are two reasons why Charles Sanders Peirce (1839-1914) ought to be labeled the logician of postmodernism — the philosopher who, more than any other, etched out the normative guidelines for postmodern thinking. The first reason (...) is that Peirce attempted to accomplish the impossible, or at least the contradictory. He launched his philosophic career with a logical critique of "Cartesianism" — his label for the modernist attempt to found philosophy on some formal principles of reasoning. He then attempted to replace the principles of Cartesian reasoning with a set of anti-modernist principles that proved themselves to be as modernist as their contraries. The second reason for giving Peirce his label is that his failures to accomplish the impossible engendered in him something he was unable to achieve willfully: a habit of self-critical yet self-affirming thinking that was neither modernist nor anti-modernist but, rather, a disciplined variety of postmodern thinking. In his later years, Peirce began to sketch out the principles of philosophic postmodernism by describing features of his own emergent habit of thinking. This sketching comes close enough to what I would label a logic of postmodernism — where the method of logic is as postmodern as the thinking it describes. (shrink)

This paper traces a lost genealogical connection between Charles S. Peirce’s later theory of signs and contemporary work in the philosophy of language by John Perry. As is shown, despite some differences, both accounts offer what might be termed a multi-level account of meaning. Moreover, it is claimed that by adopting a ‘Peircian turn’ in his theory, Perry might overcome alleged shortcomings in his account of cognitive significance.

Interpretations of Peirce’s development after 1898 often mix three kinds of arguments: one argument about belief, one argument about philosophy and practice, and one argument about the causal role of James’s writings on Peirce’s development. I shall focus here on the last two points: theory and practice and the alleged role of James. James’s role in Peirce’s development is somewhat overestimated and one can doubt Peirce’s worries about the dogmatic use of the scientific method and of (...) philosophy in morals are conditioned by James’s writings only. Peirce’s re-readings and refinements of his Illustrations started no later than the early 1880s, at a time when James was not as central a reference as it became after 1900 for the philosophic stage. To support that claim, I wish to focus here on one particular point: the distrust towards those who try to “mingle” philosophy and practice is by no means a new theme in the 1890s. One of the most telling examples of such a claim is the 1885 review of Royce’s The Religious Aspect of Philosophy, some thirteen years before the quarrel over pragmatism started. (shrink)

"It is difficult not to notice a curious unrest in the philosophic atmosphere of the time, a loosening of old landmarks, a softening of oppositions, a mutual borrowing from one another on the part of systems anciently closed, and an interest in new suggestions, however vague, as if the one thing sure were the inadequacy of extant school-solutions. The dissatisfactions with these seems due for the most part to a feeling that they are too abstract and academic. Life is confused (...) and superabundant, and what the younger generation appears to crave is more of the temperament of life in its philosophy, even though it were at some cost of logical rigor and formal purity." - William James (1904). -/- Abstract: The study of model-based reasoning (MBR) is one of the most interesting recent developments at the intersection of psychology and the philosophy of science. Although a broad and eclectic area of inquiry, one central axis by which MBR connects these disciplines is anchored at one end in theories of internal reasoning (in cognitive science), and at the other, in C.S. Peirce’s semiotics (in philosophy). In this paper, we attempt to show that Peirce’s semiotics actually has more natural affinity on the psychological side with ecological psychology, as originated by James J. Gibson and especially Egon Brunswik, than it does with non-interactionist approaches to cognitive science. In particular, we highlight the strong ties we believe to exist between the triarchic structure of semiotics as conceived by Peirce, and the similar triarchic stucture of Brunswik’s lens model of organismic achievement in irreducibly uncertain ecologies. The lens model, considered as a theory of creative abduction, provides a concrete instantiation of at least one, albeit limited, interpretation of Peirce’s semiotics, one that we believe could be quite fruitful in future theoretical and empirical investigations of MBR in both science an philosophy.

In this paper Peirce's notion of sign is studied to try to characterize the artistic sign as representation. Then, some considerations about the work of art as a sign are developed involving three elements: experience, expression and interpretation. Finally it is concluded that beauty requires for Peirce a peculiar balance, the imaginative conjunction of the sensible and the reasonable in an artistic sign; it requires moreover the expression of something that transcends the sensible; it requires, as a sign, (...) an interpretation which is not exact and which implies growth. It requires, finally, love, because an artist will only reach beauty guided by agape updating and harmonizing possibilities through abduction, that is, creating new signs that give form to what does not have it; the artist only reaches beauty when he loves what he does and when he can express himself freely. -/- En este artículo se estudia, en primer lugar, la noción de signo de Peirce para tratar de caracterizar después el signo artístico como representación. Se desarrollan enseguida algunas consideraciones sobre la obra de arte como signo que como tal conlleva tres elementos: experiencia, expresión e interpretación. Finalmente se concluye que la belleza requiere para Peirce un peculiar equilibrio, la conjunción imaginativa de lo sensible y lo razonable en un signo artístico; requiere además la expresión de algo que trasciende lo sensible; requiere, en tanto signo, de una interpretación que no es exacta y que implica crecimiento. Requiere, por último, amor, pues el artista solo alcanzará lo bello cuando sea guiado por el ágape y a través de la abducción vaya actualizando y armonizando posibilidades, creando nuevos signos que den forma a lo que no la tiene, cuando ame lo que hace y se exprese libremente.

This article is an effort to understand how the Peirce's Arrow (Logical NOR), as a logical operation, can act within the concept of Ludwig Wittgenstein's language-game, considering that the language game is a satzsystem, i.e., a system of propositions. To accomplish this task, we will cover four steps: (1) understand the possible relationship of the thought of C. S. Peirce with the founding trio of analytic philosophy, namely Frege-RussellWittgenstein, looking for similarities between the logic of Peirce and (...) his students (notably Christine Ladd and O.H. Mitchell) with a New Wittgenstein’s approach, which sees Early Wittgenstein (Tractatus Logico-Philosophicus),Middle Wittgenstein and Last Wittgenstein (Philosophical Investigations) while a coherent way of thinking and not a theoretical break; (2) describe the operation of the Peirce’s Arrow (Logical NOR) as a logical connective; (3)understand the notion of satzsystem (Middle Wittgenstein) and the possibility of applying the concept of language-game (Last Wittgenstein) on it; and (4) understand how the Logical NOR can operate within a satzsystem. The goal here is a search for the logic of the language-game and how the logical ideas of C. S. Peirce can help in this construction. And this construction might be interesting for a better understanding of the analytic philosophy of language. (shrink)

An Omega Point Theory says that reality is making progress from some initial state to some final state. It moves from some Alpha Point (the initial state) to some Omega Point (the final state). The progress is an increase in some quality. For example, reality is making progress from the chaotic to the orderly; or it is making progress from the simple to the complex; or from the mindless to the mental; or from evil to good. Here we focus on (...) the Omega Point theory of Peirce. An Omega Point Theory is an evolutionary cosmology – it says that the universe is evolving from the Alpha Point to the Omega Point. Peirce refers to his evolutionary cosmology as a Cosmogonic Philosophy would suppose that in the beginning – infinitely remote – there was a chaos of unpersonalized feeling, which being without connection or regularity would properly be without existence. This feeling, sporting here and there in pure arbitrariness, would have started the germ of a generalizing tendency. Its other sportings would be evanescent, but this would have a growing virtue. Thus the tendency to habit would be started; and from this, with the other principles of evolution, all the regularities of the universe would be evolved. At any time, however, an element of pure chance survives and will remain until the world becomes an absolutely perfect, rational, and symmetrical system, in which mind is at last crystallized in the infinitely distant future.

Argumenta-se aqui que a melhor interpretação da estética de Peirce é como uma ciência normativa de fins ideais. As influências de Peirce neste particular incluem a noção de kalos de Platão, A educação estética do homem de Friedrich Schiller, e a arquitetônica kantiana. Baseada principalmente nos rascunhos de Minute Logic em 1902 e as Palestras de Harvard em 1903, as características essenciais de uma ciência normativa são discutidas e a relação da estética às outras duas ciências normativas da (...) lógica e da ética é analisada. O conceito de Peirce de bondade estética é desenvolvido, e os critérios para o que ele considera como um summum bonum são examinados. As próprias formulações de Peirce do summum bonum são examinados, inclusive sua noção de razoabilidade concreta, como também uma explicação interessante dos ideais fundamentais encontrada em um fragmento de manuscrito de 1903. O artigo conclui com uma discussão entre o que é chamado de estética positiva e negativa de Peirce, entendido como duas abordagens diferentes à formulação de fins ideais. (shrink)
