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.

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.

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.

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.

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.

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. -/- .

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)

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 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.

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 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.

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.
