This paper argues that we can acknowledge the existence of moral truths and moral progress without being committed to moral realism. Rather than defending this claim through the more familiar route of the attempted analysis of the ontological commitments of moral claims, I show how moral belief change for the better shares certain features with theoretical progress in the natural sciences. Proponents of the better theory are able to convince their peers that it is formally and empirically superior to its (...) rivals, and the better theory may be promoted to the status of the truth. Yet there is no 'decision-procedure' for ethics any more than there is for molecular biology. The betterness of true theories can be grasped through what I term 'undirectional narratives' of progress. And while there are true moral claims and perhaps numerous moral truths yet to be discovered, we should reject currently popular forms of moral realism with bivalence. Some moral claims lend themselves to the construction of fully reversible, bi-directional narratives and are likely neither true nor false. (shrink)

Phenomenology has been described as a “non-argumentocentric” way of doing philosophy, reflecting that the philosophical focus is on generating adequate descriptions of experience. But it should not be described as an argument-free zone, regardless of whether this is intended as a descriptive claim about the work of the “usual suspects” or a normative claim about how phenomenology ought to be properly practiced. If phenomenology is always at least partly in the business of arguments, then it is worth giving further attention (...) to the role and form of phenomenological argumentation, how it interacts with its more strictly descriptive component, and the status of phenomenological claims regarding conditions for various kinds of experience. I contend that different versions of phenomenological reasoning encroach upon argument forms that are commonly thought to be antithetical to phenomenology, notably abductive reasoning, understood in terms of its role in both hypothesis generation and in terms of justification. This paper identifies two main steps to making this case. The first step takes seriously the consequences of the intrinsically dialectical aspect of phenomenology in intersection with other modes of philosophy, the natural attitude, and non-philosophy. The second step focuses on transcendental reflection and arguments about the conditions/structures they contain. Together, these two steps aim to rescue phenomenology from the objection that it has an “ostrich epistemology” with regard to the ostensible purity of description, the intuition of essences, or the “conditions” ascertained through transcendental reflection.

It is often thought that consciousness has a qualitative dimension that cannot be tracked by science. Recently, however, some philosophers have argued that this worry stems not from an elusive feature of the mind, but from the special nature of the concepts used to describe conscious states. Marc Champagne draws on the neglected branch of philosophy of signs or semiotics to develop a new take on this strategy. The term “semiotics” was introduced by John Locke in the modern period – (...) its etymology is ancient Greek, and its theoretical underpinnings are medieval. Charles Sanders Peirce made major advances in semiotics, so he can act as a pipeline for these forgotten ideas. Most philosophers know Peirce as the founder of American pragmatism, but few know that he also coined the term “qualia,” which is meant to capture the intrinsic feel of an experience. Since pragmatic verification and qualia are now seen as conflicting commitments, Champagne endeavors to understand how Peirce could (or thought he could) have it both ways. The key, he suggests, is to understand how humans can insert distinctions between features that are always bound. Recent attempts to take qualities seriously have resulted in versions of panpsychism, but Champagne outlines a more plausible way to achieve this. So, while semiotics has until now been the least known branch of philosophy ending in –ics, his book shows how a better understanding of that branch can move one of the liveliest debates in philosophy forward.

Semiotics, in the guise of the limited Saussurean semiology, has been widely used in the humanities and in cultural studies for the past 20 to 30 years at least. With the advent, nearly 20 years ago, of the environmental humanities, including the new field of humanities animal studies, the weaknesses of this mode of analysis became increasingly clear. This essay forms part of a larger attempt to develop a Peirce-informed biosemiotic theory capable of affording conceptual tools for the broad-based study (...) of human and nonhuman natural and cultural developmental ecologies. It is particularly concerned to develop a biosemiotic, and hence non-reductive, account of aesthetic experience in which function consists in the growth of knowledge. Based on the role of chance, and thus creativity, in natural and cultural evolutionary systems, this essay uses poetry and poetic theory in order to argue that chance is a habit-upsetting happenstance whereby something which has the potential to become a sign , or to become a bearer of meaning, actually does become a sign to some living thing.

This article discusses the use of a pragmatic approach as the philosophical foundation of pedagogy in Finnish universities of applied sciences. It is presented that the mission of the universities of applied sciences falls into the interpretive paradigm of social sciences. This view is used as a starting point for a discussion about pragmatism in higher education. The Learning by Developing (LbD) action model is introduced, analyzed and compared to pragmatism. The paper concludes that, at least in practice-oriented academic subjects, (...) a pragmatic approach to pedagogy, as well as the LbD action model, is effective and could be considered in several universities as the basis of philosophy of pedagogy.

Wim Wenders' film Wings of Desire tells the story of an angel who wishes to become mortal in order to know the simple joy of human life. Told from the angel's point of view, the film is shot in black and white. But at the very instant the angel perceives the realities of human experience, the film blossoms into colour. In this article, I use this film to illustrate and explore Peirce's notion of experience and his claim that ‘experience is (...) our great and only teacher’. In his 1903 Harvard lectures, Peirce placed phenomenology at the heart of his philosophy, while outlining a notion of ‘experience’ that clearly integrates his semiotics, phenomenology and pragmatism. To Peirce, experience is a ‘brutally produced conscious effect’ that comes ‘out of practice’ and is a ‘forcible modification of our ways of thinking’. But as this modification is generated by the actions and flows of signs, it is pertinent to read Peirce's notion of experience in relation to his notion of semiosis. Consequently, a Peircean reading of Wings of Desire not only helps to explore how experience teaches, but also the ways in which the rudeness of experience cannot be fully understood without considering the sign's action.

In this paper, I argue that Darwin's On the Origin of Species can be interpreted as the culmination of an extended exercise of what Kant called ‘the reflecting power of judgement’ that issued in a form of reasoning that Hegel associates with inference by analogy and that Peirce associates with hypothesis and later assimilates to abduction. After some exegetical and rationally reconstructive work, I support this reading by showing that Darwin's theory of natural selection gave us a way of understanding (...) the purposive character of organic generation and growth that does not rely on an analogy with intentional agency and outlining some of the uses to which this new understanding was put in reasoning about mind and society by American intellectuals in the second half of the nineteenth century. In the process I hope to shed some light on the relationship between mechanistic and purposive explanation in judgements of nature. (shrink)

The paper gives a detailed reconstruction and discussion of Peirce’s doctrine of propositions, so-called Dicisigns, developed in the years around 1900. The special features different from the logical mainstream are highlighted: the functional definition not dependent upon conscious stances nor human language, the semiotic characterization extending propositions and quasi-propositions to cover prelinguistic and prehuman occurrences of signs, the relations of Dicisigns to the conception of facts, of diagrammatical reasoning, of icons and indices, of meanings, of objects, of syntax in Peirce’s (...) logic-as-semiotics.

This paper studies a generalization of rational choice theory. I briefly review the motivations that Helzner gives for his conditional choice construction . Then, I focus on the important class of conditional choice functions with vacuous second tiers. This class is interesting for both formal and philosophical reasons. I argue that this class makes explicit one of conditional choice’s normative motivations in terms of an account of neutrality advocated within a certain tradition in decision theory. The observations recorded—several of which (...) are generalizations of central results in the standard theory of rational choice—are intended to provide further insight into how conditional choice generalizes the standard account and are offered as additional evidence of the fruitfulness of the conditional choice framework.

When William James published Pragmatism, he gave it a subtitle: A New Name for Some Old Ways of Thinking. In this article, I argue that pragmatism is an epistemological method for articulating success in, and between, a plurality of practices, and that this articulation helped James develop radical empiricism. I contend that this pluralistic philosophical methodology is evident in James’s approach to philosophy of religion, and that this method is also exemplified in the work of one of James’s most famous (...) students, W.E.B. Du Bois, specifically in the closing chapter of The Souls of Black Folk, “Of the Sorrow Songs.” I argue that “Sorrow Songs” can be read as an epistemological text, and that once one identifies the epistemic standards of pragmatism and radical empiricism in the text, it’s possible to identify an implicit case for moderate fideism in “Sorrow Songs.” I contend that this case illuminates the pluralistic philosophical methodology James worked throughout his career to develop, and that the James-Du Bois approach to philosophy may even help locate the epistemic value of other religious practices, beyond the singing of hymns, and identify terrain mainstream philosophy has long neglected.

This paper considers the relation between the American pragmatist Charles Sanders Peirce and the German idealist G. W. F. Hegel . While Peirce engaged with Hegel’s thought quite extensively, his often critical comments on the latter have made it hard to see any genuine common ground between the two; recent ways of reading Hegel, however, suggest how this might be possible, where the connections between their respective metaphysical positions and views of the categories are explored here. Issues relating to their (...) epistemology and philosophies of languages are considered in a companion article. (shrink)

The main aim of this article is to describe central elements of, and the relationships among, three interrelated domains of inquiry. The first domain is Charles Peirce's semiotic theory which offers five concepts of special relevance to the other two domains: primary components of the triadic sign, including the object, representamen, and interpretant; the unceasing process of semiosis, or continuous growth of the developing sign; the three forms of inference, of which Peirce's notion of abduction is of special interest; the (...) element of surprise in experience, and the universal categories of Firstness, Secondness, and Thirdness that ground Peirce's overarching theory. The second domain incorporates the discipline of psychosemiotics, which is defined as the study of how we learn, understand, and use the signs of culture. The article outlines the nature and scope of psychosemiotics and emphasizes its grounding in Peircean semiotics, meaning‐making, and the five concepts listed above. The claim will be made that signs, semiosis, and meaning act through the seven signways outlined in the article and thereby bind the individual into the surrounding physical and cultural environments. The third domain is formal education, for which implications are presented as derived from Peircean theory and viewed through the psychosemiotic lens. In this perspective, all forms of education are semiotic processes grounded in signs and meaning‐making. Further, formal education consists of learning a wide variety of culturally‐valued signs by way of the seven signways and through processes that often differ from a technocratic, standards‐driven, accountability‐oriented approach to learning and instruction.

Pragmatism is often thought to be incompatible with realism, the view that there are knowable mind-independent facts, objects, or properties. In this article, I show that there are, in fact, realist versions of pragmatism and argue that a realist pragmatism of the right sort can make important contributions to such fields as religious ethics and philosophy of religion. Using William James's pragmatism as my primary example, I show (1) that James defended realist and pluralist views in metaphysics, epistemology, ethics, and (...) philosophy of religion, and (2) that these views not only cohere with his pragmatism but indeed are basic to it. After arguing that James's pragmatism provides a credible and useful approach to a number of basic philosophical and religious issues, I conclude by reflecting on some ways in which we can apply and potentially improve James's views in the study of religion.

Establishing trust among individual agents has defined a central issue of practical reasoning since the dawning of liberal individualism. Hobbes was convinced that foolish self-interest always threatens to defeat uncompelled cooperation when one can gain by abandoning a joint effort. Against this philosophical background, scientific studies of human beings display a surprisingly cooperative species. It would seem to follow that biologically inherited characteristics impair our reason. The response proposed here distinguishes rationality and reasonableness as two forms of good reasoning. One (...) is consistent with the model of strategic rationality, the other with a model of emotional relationship. From the Hobbesian perspective trusting agents are not rational if their makeup discourages advantageous defection even when one knows it will not be detected or punished. The point is indecisive because reasonable trust insulates cooperative action from the factors that have appeared to make it chancy or unstable without some enforcing power. A critical theme is that trust does not simply rest upon a biological disposition to conform to norms. That would explain but not justify aversion to defection. In fact, trust can survive reasoned challenges to norm-conforming dispositions, displaying the responsible social animal living along with the rational individual. (shrink)

The author suggests that educational philosophy should benefit from addressing questions traditionally asked within discourse in the philosophy of mind, namely: the relation between the mind and world and the problems of intentionality , meaning, and representation. Peirce's semiotics and his category of creative abduction provide a novel conceptual framework for exploring these questions. A model of reasoning and learning, based on Peirce's triadic logic of relations, is analysed. This model, it is argued, is fruitful for overcoming the paradox of (...) new knowledge that was first debated by Socrates in his dialogue with Meno. (shrink)

It is suggested that Charles Sanders Peirce's triadic semiotics provides a framework for a diagrammatic representation of a sign's proper structure. The action of signs is described at the logical and psychological levels. The role of (unconscious) abductive inference is analyzed, and a diagram of reasoning is offered. A series of interpretants transform brute facts into interpretable signs thereby providing human experience with value or meaning. The triadic structure helps in de-mystifying the relations between Penrose's three worlds when the latter (...) are considered as constituting a semiotic triangle. (shrink)

The recent literature on genocide shows signs of taking what might be called a “processual turn,” with genocide increasingly understood as a contingent process rather than a singular event. But while this second generation's turn may be clear to those within the literature, the theory guiding the change is insufficiently specified. The theory regarding process and contingency is implicit, and, as such, genocide theory does not realize its full generative potential. The primary goal of this article is to provide a (...) more robust theoretical framework for making sense of the continually evolving dimensions of genocide. It builds on the literature's existing foundations, most notably Mann's (2005) notion of “contingent escalations.” In the spirit of the recent revival of American Pragmatism in sociology, it draws on the work of Dewey, Mills, Follett, and Addams (among others) as part of a theoretical reconstruction using pragmatist concepts such as rupture, perplexity, vocabularies of motive, and experimentation to consider examples from the Rwandan genocide and show how we might explore the potential for non-teleological intentionality on the part of genocidal actors. The result is an enhanced theoretical framework that offers “fresh eyes” for considering one of the worst (and most under-theorized) social problems. (shrink)

This essay employs Charles Peirce’s triadic semiotics in order to develop a biosemiotic theory of life that is capable of illuminating the function of information in living systems. Specifically, I argue that the relationship between biological information structures , selecting environments, and the adapted bodily processes of living organisms is aptly modelled by the irreducibly triadic relationship between Peirce’s sign, object, and interpretant, respectively. In each instance of information-based semiosis, the information structure is a complex informational sign that represents the (...) informational object ; and the bodily, behavioral, mental, or intellectual processes that are organized by the informational sign to more or less accurately interpret the present environment constitute a complex informational interpretant—a living, interpreting organism. The essay begins by discussing the precise sense in which this biosemiotic theory is based upon Charles Peirce’s semiotic theory. Next, the theory is developed at length in relation to genetic information structures. Finally, I present a brief outline of how the theory applies to neural and linguistic information structures. The essay concludes with a reflection upon the anti-reductionist implications of the theory. (shrink)

The starting point for this article is the question of the relationship between Darwinism and Christian theology. I suggest that evolutionary theory presents three broad issues of relevance to theology: the phenomena ofcontinuity, naturalism, andcontingency. In order to formulate a theological response to these issues I draw on the semiotics (theory of signs) and cosmology of the American philosopher Charles Sanders Peirce. Peirce developed a triadic theory of signs, underpinned by a threefold system of metaphysical categories. I propose a semiotic (...) model of the Trinity based on Peirce's semiotics and categories. According to this model the sign‐processes (such as the genetic “code”) that are fundamental to life may be understood as vestiges of the Trinity in creation. I use the semiotic model to develop a theology of nature that addresses the issues raised by evolutionary theory. The semiotic model amounts to a proposal for a new metaphysical framework within which to understand the relationship between God and creation and between theology and science. (shrink)

The new social theories of practice have been inspired by Wittgenstein's late philosophy, phenomenology and more recent sociological theories. They regard embodied skills and routinized, mostly unconscious habits as a key foundation of human practice and knowledge. This position leads to an overstatement of the significance of the habitual dimension of practice. As several critics have suggested this approach omits the problems of transformative agency and change of practices. In turn classical practice theories, activity theory and pragmatism have analyzed the (...) mechanisms of change. Pragmatism suggests that a crisis of a habit calls for reflection. Through working hypotheses and experimentation this leads to a transformation of a practice. Activity theory introduced the concept of remediation. A collective elaboration of shared mediational artefacts is needed to transform an activity. (shrink)

Property is a complex sign in semiotics. It is also the source of tension and conflict in law. This paper examines property in triadic terms consisting of what Charles S. Peirce would identify as the icon (firstness), the index (secondness), and the symbol (thirdness). From this perspective the paper explores the ideas of place, space, and time at the iconic level of the sign of property. Discussion addresses the way in which property serves as a coded system for communicating information (...) about a given community’s values and its cultural-interpretive hierarchy. Much like an aboriginal songline, property functions as a way of imprinting the land with impressions of social ordering related to place, space, and time. In the context of global trade we therefore observe property conflicts which are sometimes not so much about the technical language of property as they are about tensions among the embedded values in competing signs of property.

In his Locke Lectures Brandom proposes to extend what he calls the project of analysis to encompass various relationships between meaning and use. As the traditional project of analysis sought to clarify various logical relations between vocabularies so Brandom’s extended project seeks to clarify various pragmatically mediated semantic relations between vocabularies. The point of the exercise in both cases is to achieve what Brandom thinks of as algebraic understanding. Because the pragmatist critique of the traditional project of analysis was precisely (...) to deny that such understanding is appropriate to the case of natural language, the very idea of an analytic pragmatism is called into question by that critique. My aim is to clarify the prospects for Brandom’s project, or at least something in the vicinity of that project, through a comparison of it with what I will suggest we can think of as Kant’s analytic pragmatism as developed by Peirce.

Abduction, deduction and induction describe forms of reasoning. Deduction and induction are discussed in the nursing literature. However, abduction has been largely neglected by nurse scholars. In this paper it is proposed that abduction may play a part in qualitative data analysis – specifically, in the identification of themes, codes, and categories. Abduction is not, in research, restricted to or associated with any particular methodology. Nevertheless, situating abduction in qualitative research facilitates the identification of three interlinked issues. First, it is (...) suggested that abductively derived claims require support from deductive and inductively sourced evidence if they are to ‘hold’ and, yet, in qualitative research this is clearly problematic. Second, difficulties in choosing between alternative plausible hypotheses are explored through an examination of the ‘generality problem’. Third, the role of background and auxiliary theories in adjudicating between hypothesis options is discussed. It is argued that if qualitative researchers utilize abductive inference in the manner suggested, then the peculiarly fallible nature of abduction must be acknowledged and, in consequence, the action guiding potential of qualitative research findings is compromised.

This article focuses on the intimate relationship between German aesthetic theory, particularly the philosophies of Kant and Schiller, and the pragmatic tradition of the nineteenth and early twentieth centuries. I argue that many aspects of Kantian aesthetic theory – his development of reflective judgement, genius, and common sense – are reflected in the thinking of C. S. Peirce. I conclude, however, that such a comparison risks selling short the way that German idealism influenced American thinkers and instead suggest that it (...) is more fruitful to concentrate on ‘aesthetic experience’. I argue that attending to the aesthetic dimensions of experience might re-orient contemporary approaches to pragmatism that continue to focus on the way that pragmatism might intervene in debates in epistemology and philosophy of language.

Bible translation over the past half century has increasingly supplemented its traditional philological-linguistic approach with a wide variety of disciplines ranging from archaeology to cultural studies. This turn toward an interdisciplinary approach is especially true of new media Bible translation with its theory and practice now engaging virtually every digital and screen medium. Not surprisingly, (new media) Bible translation has discovered the field of semiotics, thanks in large measure to the work of translation scholars such as Dinda L. Gorlée and (...) Ubaldo Stecconi, whose pioneering research into Charles Sanders Peirce has unearthed a gold mine of conceptual and even practical applications of semiotics to translation research, training, evaluation, and production. In this essay, we set out some of the foundational elements of Peircean semiotics in its application to Bible translation, including new media Bible translation. In particular, the insights of semiotics into the process of sign production and meaning making will add exponentially to the resources for Bible translators. (shrink)

The organic unity between the head and the vital arms of the octopus is proposed as a metaphor for science and religion as an academic field. While the specific object of the field is to pursue second-order reflections on existing and possible relations between sciences and religions, it is argued that several aspects of realism and normativity are constitutive to the field. The vital arms of the field are related to engagements with distinctive scientific theories, specialized philosophy of science, representative (...) theological proposals, and the input from the study of world religions.

Mimicry and deception are two important issues in studies about animal communication. The reliability of animal signs and the problem of the benefits of deceiving in sign exchanges are interesting topics in the evolution of communication. In this paper, we intend to contribute to an understanding of deception by studying the case of aggressive signal mimicry in fireflies, investigated by James Lloyd. Firefly femmes fatales are specialized in mimicking the mating signals of other species of fireflies with the purpose of (...) attracting responding males to become their prey. These aggressive mimics are a major factor in the survival and reproduction of both prey and predator. It is a case of deception through active falsification of information that leads to efficient predation by femmes fatales fireflies and triggered evolutionary processes in their preys’ communicative behaviors. There are even nested coevolutionary interactions between these fireflies, leading to a remarkable system of deceptive and counterdeceptive signaling behaviors. We develop here a semiotic model of firefly deception and also consider ideas advanced by Lloyd about the evolution of communication, acknowledging that deception can be part of the explanation of why communication evolves towards increasing complexity. Increasingly complex sign exchanges between fireflies evolve in an extremely slow pace. Even if deceptive maneuvers are played out time and time again between particular firefly individuals, the evolution of the next level of complexity—and thus the next utterance in the dialogue between species—is likely to take an immense amount of generations.

The analysis of theory-confirmation generally takes the deductive form: show that a theory in conjunction with physical data and auxiliary hypotheses yield a prediction about phenomena; verify the prediction; provide a quantitative measure of the degree of theory-confirmation this yields. The issue of confirmation for an entire framework either does not arise, or is dismissed in so far as frameworks are thought not to be the kind of thing that admits scientific confirmation. I argue that there is another form of (...) scientific reasoning that has not received philosophical attention, what I call Newtonian abduction, that does provide confirmation for frameworks as a whole, and does so in two novel ways. I further argue that Newtonian abduction is at least as important a form of reasoning in science as standard deductive and inductive forms. The form is beautifully summed up by Maxwell : “The true method of physical reasoning is to begin with the phenomena and to deduce the forces from them by a direct application of the equations of motion.”.

This paper discusses the history of the confusion and controversies over whether the definition of consequence presented in the 11-page 1936 Tarski consequence-definition paper is based on a monistic fixed-universe framework?like Begriffsschrift and Principia Mathematica. Monistic fixed-universe frameworks, common in pre-WWII logic, keep the range of the individual variables fixed as the class of all individuals. The contrary alternative is that the definition is predicated on a pluralistic multiple-universe framework?like the 1931 Gödel incompleteness paper. A pluralistic multiple-universe framework recognizes multiple (...) universes of discourse serving as different ranges of the individual variables in different interpretations?as in post-WWII model theory. In the early 1960s, many logicians?mistakenly, as we show?held the ?contrary alternative? that Tarski 1936 had already adopted a Gödel-type, pluralistic, multiple-universe framework. We explain that Tarski had not yet shifted out of the monistic, Frege?Russell, fixed-universe paradigm. We further argue that between his Principia-influenced pre-WWII Warsaw period and his model-theoretic post-WWII Berkeley period, Tarski's philosophy underwent many other radical changes. (shrink)

Demonstrative logic, the study of demonstration as opposed to persuasion, is the subject of Aristotle's two-volume Analytics. Many examples are geometrical. Demonstration produces knowledge (of the truth of propositions). Persuasion merely produces opinion. Aristotle presented a general truth-and-consequence conception of demonstration meant to apply to all demonstrations. According to him, a demonstration, which normally proves a conclusion not previously known to be true, is an extended argumentation beginning with premises known to be truths and containing a chain of reasoning showing (...) by deductively evident steps that its conclusion is a consequence of its premises. In particular, a demonstration is a deduction whose premises are known to be true. Aristotle's general theory of demonstration required a prior general theory of deduction presented in the Prior Analytics. His general immediate-deduction-chaining conception of deduction was meant to apply to all deductions. According to him, any deduction that is not immediately evident is an extended argumentation that involves a chaining of intermediate immediately evident steps that shows its final conclusion to follow logically from its premises. To illustrate his general theory of deduction, he presented an ingeniously simple and mathematically precise special case traditionally known as the categorical syllogistic. (shrink)

Résumé -/- Dans son premier livre (Philosophie de l’arithmétique 1891), Husserl élabore une très intéressante philosophie des mathématiques. Les concepts mathématiques sont interprétés comme des concepts de « deuxième ordre » auxquels on accède par une réflexion sur nos opérations mentales de numération. Il s’ensuit que la vérité de la proposition : « il y a trois pommes sur la table » ne consiste pas dans une relation mythique quelconque avec la réalité extérieure au psychique (où le nombre trois doit (...) être exemplifié de quelque manière), mais bien dans le fait que les pommes sur la table peuvent être dénombrées correctement en tant qu’elles sont au nombre de trois. Nous avons affaire ici à une position « antiréaliste » fondant la vérité mathématique non pas dans un monde platonicien, mais bien sur le concept de rectitude de nos opérations formelles. -/- Abstract -/- In his first book (Philosophy of Arithmetic 1891) Husserl develops a very interesting philosophy of mathematics. Mathematical concepts are interpreted as « second order » concepts gained by reflection on our mental operations of counting. Accordingly the truth of the proposition « There are three apples on the table » consists not in any mythical relation to the extra-mental reality (where the number three should be somehow exemplified), but rather in the fact that the apples on the table can be correctly counted as three. We have here an « anti-realist » position grounding the mathematical truth not in platonic realms, but rather in the concept of correctness of our formal operations. (shrink)

This paper suggests that it is largely a want of notional distinctions which fosters the “explanatory gap” that has beset the study of consciousness since T. Nagel’s revival of the topic. Modifying Ned Block’s controversial claim that we should countenance a “phenomenal-consciousness” which exists in its own right, we argue that there is a way to recuperate the intuitions he appeals to without engaging in an onerous reification of the facet in question. By renewing with the full type/token/tone trichotomy developed (...) by C. S. Peirce, we think the distinctness Block calls attention to can be seen as stemming not from any separate module lurking within the mind, but rather from our ability to prescind qualities from occurrences.

Following recent work by Don Ross (Ross, 2000; Ross & Spurrett, 2004), I contrast the influential theories of Daniel Dennett and Paul Churchland in information-theoretic terms. Dennett makes much of the fact that the morphological shorthand which emerges before a witness as she looks upon cohesive aggregates of matter commands some measure of predictive power. This, for him, speaks against eliminating recourse to an intentional vocabulary. By contrast, the eliminative materialism defended by Churchland does not gloss such informational compressibility as (...) an explanatory desideratum, and thus regards the informational noise which accrues at higher levels of description as patently unacceptable. Yet, since it is unlikely, as Ross, Ladyman, and Collier (2007) have recently suggested, that anything remains once we subtract the appeal to patterns, I argue that the ubiquity of informational compression in scientific explanation seriously undermines the claim that talk of the mental could be eliminated.

I articulate Charles S. Peirce’s philosophy of mathematical education as related to his conception of mathematics, the nature of its method of inquiry, and especially, the reasoning abilities required for mathematical inquiry. The main thesis is that Peirce’s philosophy of mathematical education primarily aims at fostering the development of the students’ semeiotic abilities of imagination, concentration, and generalization required for conducting mathematical inquiry by way of experimentation upon diagrams. This involves an emphasis on the relation between theory and practice and (...) between mathematics and other fields including the arts and sciences. For achieving its goals, the article is divided in three sections. First, I expound Peirce’s philosophical account of mathematical reasoning. Second, I illustrate this account by way of a geometrical example, placing special emphasis on its relation to mathematical education. Finally, I put forth some Peircean philosophical principles for mathematical education. (shrink)

As an economist, I was raised on the milk of prescriptive consequentialism. The theoretical architecture of rational choice, welfare economics, and its applied version—benefit-cost analysis—was offered up as the definitive answer to a wide range of public policy problems.

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 article examines the contention that the central concepts of C. S. Peirce’s semeiotic are inherently communicational. It is argued that the Peircean approach avoids the pitfalls of objectivism and constructivism, rendering the sign-user neither a passive recipient nor an omnipotent creator of meaning. Consequently, semeiotic may serve as a useful general framework for studies of learning processes.
