I argue that Scotus's formal distinction is a mereological fusion relation rather than an identity relation. I construct mereological models which adequately represent Scotus's theory.

Much discussion of meaning by philosophers over the last 300 years has been predicated on a Cartesian first-person authority (i.e. “infallibilism”) with respect to what one’s terms mean. However this has problems making sense of the way the meanings of scientific terms develop, an increase in scientific knowledge over and above scientists’ ability to quantify over new entities. Although a recent conspicuous embrace of rigid designation has broken up traditional meaning-infallibilism to some extent, this new dimension to the meaning of (...) terms such as “water” is yet to receive a principled epistemological undergirding (beyond the deliverances of “intuition” with respect to certain somewhat unusual possible worlds). Charles Peirce’s distinctive, naturalistic philosophy of language is mined to provide a more thoroughly fallibilist, and thus more realist, approach to meaning, with the requisite epistemology. Both his pragmatism and his triadic account of representation, it is argued, produce an original approach to meaning, analysing it in processual rather than objectual terms, and opening a distinction between “meaning for us”, the meaning a term has at any given time for any given community and “meaning simpliciter”. the way use of a given term develops over time (often due to a posteriori input from the world which is unable to be anticipated in advance). This account provocatively undermines a certain distinction between “semantics” and “ontology” which is often taken for granted in discussions of realism. (shrink)

SUMMARY Major theories of philosophical psychology and philosophy of mind are examined on the basis of the fundamental questions of ontology, metaphysics, epistemology, semantics and logic. The result is the choice between language of eliminative reductionism and dualism, neither of which answers properly the relation between mind and body. In the search for a non–dualistic and non–reductive language, Wittgenstein’s notion of language–games as the representative links between language and the world is considered together with Peirce’s semeiosis of cognition. The result (...) is a redefined notion of cognition as the goal–oriented ability to instantiate strategies from the rules of the language–games. Cognition is considered within the four-dimensional languagegames: rules/strategies, primitive/complete language-games, family-resemblances/forms of life, and non-temporal continuum as the language-games’ modality. Cognition is seen as a continuum process of non–individualized elements that unites perception, volition, emotion, will and thought against the commonly accepted understandings of cognition in exclusive terms of perception and thinking. The alternative to the mind/body problem is the continuity of cognition where rules and strategies, syntax and semantics, are considered inseparable within language–games. This continuity of cognition is explained in terms of virtual (univocal) identity, replacing the old philosophical paradigm of the mind/body problem. -/- SOMMARIO Le teorie maggiori della psicologia filosofica e filosofia della mente sono esaminate a partire dalle questioni fondamentali di ontologia, metafisica, epistemologia, semantica e logica. Il risultato è la scelta tra un linguaggio riduzionista eliminativo e un dualismo che però non confronta in modo adeguato la relazione tra mente e corpo. Nella ricerca per un linguaggio non-dualistico e non-riduttivo, viene considerata la nozione del gioco linguistico di Wittgenstein come un legame rappresentativo tra il linguaggio e il mondo insieme con la semiosi cognitiva di Peirce. Il risultato è la nozione ridefinita della cognizione come abilità goal-orientata di creare le strategie dalle regole dei giochi linguistici. La cognizione è considerata entro le quattro dimensioni dei giochi linguistici: regole/strategie, giochi linguistici primitivi/completi, somiglianze di famiglia/forme di vita, e la continuità atemporale come la modalità dei giochi linguistici. La cognizione diventa un processo continuo degli elementi non-individualizzati che tende ad unificare la percezione, volizione, emozione, la volontà e il pensiero contro un concetto generalmente accettato di vedere la cognizione nei termini esclusivamente di percezione e di pensiero. L’alternativa al problema della mente/corpo è la continuità della cognizione, dove le regole e le strategie, la sintassi e la semantica, sono considerate inseparabili nei giochi linguistici. Questa continuità della cognizione è spiegata nei termini dell’identità virtuale (univoca) sostituendo un paradigma filosofico previo del problema della mente/corpo. (shrink)

Koopman’s book revolves around the notion of transition, which he proposes is one of the central ideas of the pragmatist tradition but one which had not previously been fully articulated yet nevertheless shapes the pragmatist attitude in philosophy. Transition, according to Koopman, denotes “those temporal structures and historical shapes in virtue of which we get from here to there”. One of the consequences of transitionalism is the understanding of critique and inquiry as historical pro...

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.

En este artículo se plantean las siguientes preguntas: primero, ¿es Peirce un realista científico? Segundo, ¿han sido relevantes las ideas de Peirce para la defensa contemporánea del realismo científico? Y tercero, ¿está el realismo científico peirceano comprometido con una metafísica de la ciencia? La respuesta a tales preguntas es positiva. En el argumento se apela tanto a consideraciones de los manuscritos de Peirce como al debate contemporáneo sobre realismo científico. Luego de algunas observaciones introductorias en la primera sección, se expone (...) brevemente en la segunda sección el realismo científico en la versión de Psillos. En la siguiente sección se argumenta que la noción de abducción peirceana ha resultado crucial en la defensa contemporánea del realismo científico. En la cuarta se exponen algunos lineamientos de la metafísica de la ciencia del realismo científico peirceano, a saber, de creencia natural y ley de la naturaleza. En la quinta sección son resumidas las razones principales expuestas en este artículo para sostener que Peirce es un realista científico cuyas ideas han resultado de vital importancia en el debate actual.

Charles S. Peirce (1839-1914) made relevant contributions to deductive logic, but he was primarily interested in the logic of science, and more especially in what he called 'abduction' (as opposed to deduction and induction), which is the process whereby hypotheses are generated in order to explain the surprising facts. Indeed, Peirce considered abduction to be at the heart not only of scientific research, but of all ordinary human activities. Nevertheless, in spite of Peirce's work and writings in the field of (...) methodology of research, scarce attention has been paid to the logic of discovery over the last hundred years, despite an impressive development not only of scientific research but also of logic. -/- Having this in mind, the exposition is divided into five parts: 1) a brief presentation of Peirce, focusing on his work as a professional scientist; 2) an exposition of the classification of inferences by the young Peirce: deduction, induction and hypothesis; 3) a sketch of the notion of abduction in the mature Peirce; 4) an exposition of the logic of surprise; and finally, by way of conclusion, 5) a discussion of this peculiar ability of guessing understood as a rational instinct. -/- .

Louis Loeb has argued that Hume is pessimistic while Peirce is optimistic about the attainment of fully stable beliefs. In contrast, we argue that Hume was optimistic about such attainment but only if the scope of philosophical investigation is limited to first-order explanatory questions. Further, we argue that Peirce, after reformulating the pragmatic maxim to accommodate the reality of counterfactuals, was pessimistic about such attainment. Finally, we articulate and respond to Peirce's objection that Hume's skeptical arguments in T 1.4.1 and (...) his commitment to common sense indicate that Hume was confused about whether we could have stable beliefs at all.

This thesis is on the history and philosophy of logic and semantics. Logic can be described as the ‘science of reasoning’, as it deals primarily with correct patterns of reasoning. However, logic as a discipline has undergone dramatic changes in the last two centuries: while for ancient and medieval philosophers it belonged essentially to the realm of language studies, it has currently become a sub-branch of mathematics. This thesis attempts to establish a dialogue between the modern and the medieval traditions (...) in logic, by means of ‘translations’ of the medieval logical theories into the modern framework of symbolic logic, i.e. formalizations. One of its conclusions is that, when properly understood within their own framework, the interest of medieval logical theories for modern investigations go beyond mere historical interest, but that a thorough conceptual analysis of such theories must be undertaken in order to avoid conceptual misprojections. While such translations of medieval into modern logic have been attempted before, the approach presented here is innovative in that attention is paid to the similarities as well as to the dissimilarities between the two traditions, and to what can be learned from the medieval masters for modern investigations in logic and semantics.

This book presents novel formalizations of three of the most important medieval logical theories: supposition, consequence and obligations. In an additional fourth part, an in-depth analysis of the concept of formalization is presented - a crucial concept in the current logical panorama, which as such receives surprisingly little attention.Although formalizations of medieval logical theories have been proposed earlier in the literature, the formalizations presented here are all based on innovative vantage points: supposition theories as algorithmic hermeneutics, theories of consequence analyzed (...) with tools borrowed from model-theory and two-dimensional semantics, and obligations as logical games. For this reason, this is perhaps the first time that these medieval logical theories are made fully accessible to the modern philosopher and logician who wishes to obtain a better grasp of them, but who has always been held back by the lack of appropriate ‘translations' into modern terms.Moreover, the book offers a reflection on the very nature of logic, a reflection that is prompted by the comparisons between medieval and modern logic, their similarities and dissimilarities. It is thus a contribution not only to the history of logic, but also to the philosophy of logic, the philosophy of language and semantics.The analysis of medieval logic is also relevant for the modern philosopher and logician in that, being the unifying methodology used across all disciplines at that time, logic really provided unity to science. It thus presents a unified model of scientific investigation, where logic plays the aggregating role. (shrink)

An overview of a philosophical movement originating in the United States of America in the 19th century.

The purpose of this paper is to offer a distinct contribution to recent attempts to understand Peirce’s normative thinking. Scholars have interpreted the real tensions in Peirce’s normative thought by conflating passages from different moments in the development of his philosophy. Extracts from Peirce’s famous 1898 lectures (when he dismissed ethics as useless) are frequently combined with later passages from 1902 onwards, when he changed his mind. This paper proceeds by tracing the growth of Peirce’s thinking about ethics and correlating (...) his conflicting positions with his theory of the categories. The approach offered here is diachronic. A diachronic approach is necessary to correct some efforts to resolve the inconsistencies in Peirce’s moral theory. Also, a categorical account is understood as essential to perceive the inner coherence of his moral philosophy and to support the view that Peirce moved from a nominalist to a realist position in ethics. By connecting Peirce’s conceptions of ethics to his theory of the categories I hope to have provided a better understanding of the structure of his normative realism. (shrink)

In this paper, I examine a puzzle that emerges from what J. P. Moreland has called the traditional realist view of quality instances. Briefly put, the puzzle is to figure out how quality instances fit into the overall structure of a concrete particular, given that the traditional realist view of quality instances prima facie seems incompatible with what might be called the traditional realist view of concrete particulars. After having discussed the traditional realist views involved and the puzzle that emerges (...) from their juxtaposition, I propose an alternative realist view of quality instances which resolves the puzzle. In short, the puzzle is solved by treating the distinction between a concrete particular and its quality instances as a distinction of reason, and by adopting the view that the individuating element of a concrete particular must also serve as its unifying element – a view which Moreland, one of traditional realism’s most stalwart contemporary defenders, rejects.

There are significant differences between the neopragmatism as formulated by Rorty, based on James’ and Dewey’s pragmatism, and what Peirce, in order to distinguish his own approach from the last two thinkers, called pragmaticism. I take in this paper the concept of solidarity as a focus, from which those differences will be implied, albeit many other points could be chosen. I highlight that the usual Rorty’s sentence beginning with ‘we pragmatists…’ shall necessarily exclude Peirce. Exemplarily, I could mention the concepts (...) of representation, which for Peirce has nothing to do with mirror, and of truth that, for him, also has no relation at all with fixed essences. Those differences will not only mark a very clear border between the two concepts of pragmatism, but also will question how the idea of community can be supported only by dialogical agreements, without the anchor of common open human experience. Pragmaticism and neopragmatism differ not only regarding their specific range of philosophical problems but, moreover, on what kind of problems they really consider as genuinely philosophical.

Firstness is the most neglected of Peirce’s categories, and is frequently held to be either elusive or inherently inconsistent. Yet, one’s implicit understanding of Firstness guides the kind of interpretation given to a wide range of his philosophy. From the starting point of his account of qualia in perceptual awareness, Firstness can be seen to be a consistent category which indicates that reality is qualitatively rich, but that its qualitative richness indicates not a realm of sense universals or any sort (...) of determinate repeatables but rather a realm of diverse and somewhat indefinite qualitative stimuli. There emerges from Peirce’s epistemic/phenomenal characterization of Firstness in perception a metaphysical category of Firstness which is neither a remnant of traditional conceptions of determinate repeatable qualities, nor a remnant of traditional conceptions of eternal Platonic possibilities. Rather, what emerges is a Firstness which attributes to reality precisely those characteristics most antithetical to such traditional conceptions. Firstness in this sense not only underlies Peirce’s radical rejection of foundationalist-antifoundationalist alternatives in epistemology, but also anticipates his rejection of the ontological alternatives offered by a tradition of substance metaphysics.

This paper focuses on one of C. S. Peirce's criticisms of G. W. F. Hegel: namely, that Hegel neglected to give sufficient weight to what Peirce calls "Secondness", in a way that put his philosophical system out of touch with reality. The nature of this criticism is explored, together with its relevant philosophical background. It is argued that while the issues Peirce raises go deep, in some respects Hegel's position is closer to his own than he may have realised, whilst (...) in others that criticism can be resisted by the Hegelian.

A common view is that Charles Peirce influenced Josiah Royce. This paper demonstrates that Josiah Royce influenced Charles Peirce. A chronology is presented, followed with a brief description of a change in Peirce’s thinking from studying the writings of Royce.

Na primeira seção, discuto a atitude ambivalente de Peirce para com os pensadores medievais – algumas avaliações elogiosas, algumas críticas duras. Na segunda parte, considero três críticas feitas por Max Fisch ao meu livro Charles Peirce and Scholastic Realism. Meu livro apresentou o realismo de Peirce como se fosse de cabo a rabo uma única posição. E eu quero ajustar isso sob a luz dos argumentos de Fisch. Desejo agora distinguir seu realismo escolástico de seu desenvolvimento contínuo do realismo. Para (...) esse fim, ofereço um significado mais preciso e restrito para “realismo escolástico” – grosso modo, um anti-platonismo no qual a natureza comum é encontrada como um elemento nas coisas. Esse significado, penso, permanece constante para Peirce; embora eu concorde com Fisch, em que isso é somente uma parte do desenvolvimento de seu realismo. Na terceira seção, desenvolvo a conexão entre a noção escolástica de potencialidade e os “would-be’s” [seriam] de Peirce. Ainda que suficientemente interessante (para mim), essa não é uma influência que o próprio Peirce reconheça. Também indico ali que Peirce chega a dispensar a noção escolástica de forma, que ele pensa ser uma perversão da posição mais útil (se não vaga) de Aristóteles. (shrink)

This essay attempts an overview of Peirce’s pragmaticist doctrine of the truth of propositions. Relying on his writings, I try to characterize his conception of the real and discuss the ways in which his peculiar scholastic metaphysics, opposing that of nominalists, is a central tenet of the pragmaticist view of truth which he strived to develop. Peirce conceived indeed real possibilities and real necessities to be just as real as actualities, those realities corresponding in nature to qualities (“firsts”), laws (“thirds”), (...) and existents (“seconds”), respectively. More specifically, I detail the peculiar mode of being of each kind of real elements and show that all three categories must be recognized at once in true propositions. This led Peirce to conclude that if propositions are general signs indeed and, as such, along with terms and arguments, are necessarily dependent on mind, it does not in the least preclude those propositions to be about, nor true of, a real world – a position which actually constitutes a necessary prerequisite for any meaningful conception of scientific inquiry. I believe that a focus on such interrelations between Peirce’s categorial account of the real and Peirce’s pragmaticist conception of truth constitutes an ideal testament to the systematic nature of his thought, which is an aspect often deflated in unspecialized literatures.
