Speculative logical theory, as provided in Hegel’s Science of Logic, consists of three main parts: the logic of being, the logic of essence, and the logic of the concept. The peculiar character of each logic’s starting point determines the most general character of each logic’s development. The present paper aims at making explicit the character of the starting-point of the third logic, the logic of the concept. This starting-point is exemplified by (...) the category of universality. It is shown (a) that the fundamental determination of this category is the harmonious unit y of self-identity and full determinacy and (b) that this unity has necessarily the logical structure of “double shining.” The latter is described in detail and justification is provided as to why it is preferred from “single shining.” I conclude the paper by defending the structure of “double shining” against certain objections raised against it by Friedrike Schick and Christian Iber.

1. There is a sense in which, quite generally, with his logic Hegel can be considered the forerunner of many projects taken up by successive (non-classical) logics—and this despite the fact that He...

ABSTRACT This article argues that Hegel’s speculative logic has an essentially rhythmic structure. Rhythm shows up in paragraphs 56–61 of the Preface to the Phenomenology of Spirit, where Hegel introduces the speculative proposition and explains his speculative logic. The article begins by analyzing some critical sections in the Preface to show how rhythm secures the formal passage of the subject into the predicate within the speculative proposition. Then, I briefly explore how Hegel’s speculative (...) logic gets taken up in the writings of Gadamer and Nancy to show how each of these thinkers renews the rhythm of Hegel’s speculative logic in their own appropriations of it. The article concludes by extending the scope of speculation, taking it from the proposition to non-propositional forms of expression, and then finally to the sensible world. (shrink)

A study of shifts in scientific strategies for measuring the living body, especially in dynamic systems theory: sheds light on Hegel's concept of measure in The Science of Logic, and the dialectical transition from categories of being to categories of essence; shows how Hegel's speculative logic anticipates and analyzes key tensions in scientific attempts to measure and conceive the dynamic agency of the body. The study's analysis of the body as having an essentially dynamic identity irreducible to (...) measurement aims to contribute to reconceiving the body, in a way that may be helpful to overcoming dualism.

Bridging from Husserl to Iamblichus, this book contributes phenomenological readings of Plotinus, Aristotle, Parmenides, and Heraclitus, in which prevalent misconceptions about the very identity of time in the phenomena of motion are corrected, and time's role in Greek philosophy recovered.

_Peirce’s Speculative Grammar: Logic as Semiotics _offers a comprehensive, philologically accurate, and exegetically ambitious developmental account of Peirce’s theory of speculative grammar. The book traces the evolution of Peirce’s grammatical writings from his early research on the classification of arguments in the 1860s up to the complex semiotic taxonomies elaborated in the first decade of the twentieth century. It will be of interest to academic specialists working on Peirce, the history of American philosophy and pragmatism, the philosophy (...) of language, the history of logic, and semiotics. (shrink)

I outline the theoretical framework of, and three research programs within American speculative philosophy of science during the period 1900-1931. One program applies verificationism to research in psychology, one investigates the methodology of research programs, and one analyses scientific explanation and other scientific concepts. The primary sources for my outline are works by Morris Raphael Cohen, Grace Andrus de Laguna, Theodore de Laguna, Edgar Arthur Singer Jr., Harold Robert Smart, and Marie Collins Swabey. I also use my outline to (...) provide a partial comparison of American speculative philosophy of science and 1930s logical positivism. My comparison suggests that logical positivism was a proposal for substantially narrowing down and winding back American philosophy of science and was based on positions that were already problematized in the American context. -/- .

This book offers new critical perspectives on the relationship between the notions of speculation, logic and reality in Hegel's thought as basis for his philosophical account of nature, history, spirit and human experience. The systematic functions of logic and pure thought are explored in their concrete forms and processual progression from subjective spirit to philosophy of right, society, the notion of habit, the idea of work, art, religion and science. Engaging the relation between the Logic and its (...) realisations, this book shows the internal tension that inhabits Hegel's philosophy at the intersection of logical speculation and concrete analysis. The investigation of this tension allows for a hermeneutical approach that demystifies the common view of Hegel's idealism as a form of abstract thought, while allowing for a new assessment of the importance of speculation for a concrete understanding of the world.

In Process and Reality, Whitehead explicitly states what he conceives his task to be: “Speculative Philosophy,” he writes, “is the endeavor to frame a coherent, logical, necessary system of general ideas in terms of which every element of our experience can be interpreted.” He then goes on to explain what he means by the key terms in this passage. By ‘in terms of which every element of our experience can be interpreted’, “I mean,” he explains, “that everything of which (...) we are conscious, as enjoyed, perceived, willed, or thought, shall have the character of a particular instance of the general scheme.” This universality, or all-comprehensiveness, of the system is interpreted in terms of two characteristics: applicability and adequacy. Whitehead explains: “Here ‘applicable’ means that some items of experience are thus interpretable, and ‘adequate’ means that there are no items incapable of such interpretation.” It is these two characteristics of the system which give an explication of the term ‘necessary’ as applied to the system of general ideas: “The metaphysical first principles can never fail of exemplification. We can never catch the actual world taking a holiday from their sway.”. (shrink)

This paper contributes to explaining the rise of logical empiricism in mid-twentieth century (North) America and to a better understanding of American philosophy of science before the dominance of logical empiricism. We show that, contrary to a number of existing histories, philosophy of science was already a distinct subfield of philosophy, one with its own approaches and issues, even before logical empiricists arrived in America. It was a form of speculative philosophy with a concern for speculative metaphysics, normative (...) issues relating to science and society and issues which later were associated with logical empiricist philosophy of science, issues such as confirmation, scientific explanation, reductionism and laws of nature. Further, philosophy of science was not primarily pragmatist in orientation. We also show, with the help of our historical characterization, that a recent account of the emergence of analytic philosophy applies to the rise of logical empiricism. It has been argued that the emergence of American analytic philosophy is partly explained by analytic philosophers’ use of key institutions, including of journals, to marginalize speculative philosophy and promote analytic philosophy. We argue that this use of institutions included the marginalization of speculative and value-laden philosophy of science and the promotion of logical empiricism. (shrink)

Resumen Se sostiene que la operación general de la silogística en la Lógica cumple con un programa trazado tempranamente por Hegel, consistente en concebir la unidad de la forma racional del silogismo y el contenido absoluto de la idea como resultado de una dialéctica inmanente a la propia forma del silogismo, mediante la cual éste abandona su carácter meramente formal y alcanza su propio concepto: ser forma objetiva o racional. Para esto se acude a la sección Subjetividad de la Doctrina (...) del Concepto, procurando reconstruir los antecedentes sistemáticos del capítulo sobre el silogismo, así como la operación específica que éste realiza en vista del tránsito a la sección Objetividad. El sentido de dicha operación consiste en la superación de un exceso que, al comienzo, la necesidad de la sustancia tiene por sobre la libertad del concepto, de lo cual resulta un exceso del concepto por sobre la sustancia. Para verificar esta operación se examinan los silogismos del estar y la necesidad, concluyendo con la determinación del tipo de objeto y de conocimiento que resulta del silogismo, y con la proyección del problema a estadios ulteriores de la Lógica, en los cuales el problema avistado adquiere un cariz marcadamente práctico.In this paper I argue that the general operation of syllogistic in the Logic fulfills a philosophical program that was early outlined by Hegel. This program conceives the unity of the rational form of the syllogism and the absolute content of the idea as a result of an immanent dialectic to the syllogism's form, by which it abandons its merely formal character and attains its own concept: being an objective or rational form. For the purposes of this argument, I analyze the Subjectivity section of the Doctrine of the Concept and reconstruct the systematic background of the chapter on syllogism, as well as the specific operation it performs in view of the transit to the Objectivity section. This operation consists in overcoming a certain excess that the necessity of the substance has, first, over the freedom of the concept, which results in an excess of the concept over the substance. To clarify this operation, I examine the syllogisms of qualitative existence and necessity. Finally, I show the determination of the type of object and knowledge that results from the syllogism and explain how this problem projects to later stages of Logic, in which the analyzed problem acquires a relevant practical aspect.

Peirce’s Speculative Grammar is a masterful chronological reconstruction of Peirce’s work on logic as semiotics, or the study of signs and the purposes to which we put them. Peirce’s writings on these topics span more than fifty years. Moreover, his manuscripts number well over 100,000 pages, many of which have yet to be published. Patently, gaining a comprehensive overview of Peirce’s writings on logic is no small feat, and Bellucci is to be celebrated for his efforts. Peirce (...) wanted to be known foremost as a logician. He did not, however, want to be known primarily as a formal logician. In a drafted lecture from 1905, he tells... (shrink)

The aim of this article is to clarify the critical role of Hegel's early logic, through an assessment of the dialectical process of sublation [Aufhebung] of the determinations of finite thinking at stake within its exposition. I want to show that the dialectical-critical work of logic has a speculative meaning for Hegel, thereby displaying the inward correspondence between critical and speculative aspects of philosophical activity. By pointing out the evidence from fragmentary texts on logic relating (...) to Hegel's teaching activity in 1801–1802, I will first put into question the idea of an introductory role of logic. In so doing I challenge a widespread reading which argues for the presence of a sharp separation between critical logic and speculative metaphysics. I will then focus on the texts on logic in the 1804–1805 Reinschrift, reading them as the worksite wherein the dawning form of a full-fledged dialectical logic is first prepared and elaborated. More generally, if this paves the way for establishing a continuity between Hegel's early and mature logic and his concept of dialectic, it is also paramount for understanding how the activity of systematic philosophy in the mature version of the system essentially constitutes an ongoing work on the forms of the finite.

In 1897, Peirce famously avows that ‘Logic, in its general sense, is, as I believe I have shown, only another name for semiotic’ (Peirce 1932, 2.227). Moreover, in his later attempts to classify di...

I argue against the use of general ‘ism’ terms such as ‘speculative realism’ and ‘correlationism’ by Harman. This use is contrasted with more nuanced readings of philosophers, referring to Bryant and DeLanda’s more subtle versions of materialism that do not fit the general label. Instead of general categories I defend Deleuze’s use of the concept of problem as studied by Bell. This argument is then developed through a close reading of Logic of Sense, against Harman’s denial of the (...) reality of relations and processes. I demonstrate that Deleuze is not a correlationist as defined by Harman, by following Sauvagnargues, Smith and Beistegui on the concepts of event and simulacrum in Logic of Sense. I then consider Deleuze’s study of language and his argument that designation, signification and manifestation rely on the concept of sense. This argument leads to a position which is neither idealism, nor materialism, because the differential processes at work in sense cannot be reduced to matter or to the subject, working instead between them and denying their independent reality.

Despite wide recognition that speculation is critical for successful science, philosophers have attended little to it. When they have, speculation has been characterized in narrowly epistemic terms: a hypothesis is speculative due to its (lack of) evidential support. These ‘evidence-first’ accounts provide little guidance for what makes speculation productive or egregious, nor how to foster the former while avoiding the latter. I examine how scientists discuss speculation and identify various functions speculations play. On this basis, I develop a ‘function-first’ (...) account of speculation. This analysis grounds a richer discussion of when speculation is egregious and when it is productive, based in both fine-grained analysis of the speculation’s purpose, and what I call the ‘epistemic situation’ scientists face.

Richard Rorty would have read these passages strategically as so much meta‐physical mumbo jumbo, yet they can "usefully" apply here. Derrida famously argued that differance was neither a word nor a concept. Rorty's dismissiveness here is typical of his transvaluative stylistics, presenting itself, as always, in commonsensical rather than counterintuitive attire. Yet Badiou's reworking of Derrida's non/concept can help us situate Rorty's philosophy in the nonplace between transvaluative legibility and illegibility, where it reads to this day. The eschewal of every (...) "conditions of possibility" rhetoric had consequences for Rorty's Critical reception – consequences that were already implicit in Consequences of Pragmatism, but which Rorty may not have foreseen. Rorty's peculiar tragedy is that he was not a proto‐cultural materialist, any more than he was a "conditions of possibility" antifoundationalist or a by now mythological logical positivist. Neither Rorty nor speculative realists are speculative, of course, in the sense that Hegel's philosophy is called "speculative.". (shrink)

Speculation: Politics, Ideology, Event develops Hegel's radical perspective of speculative thought as a way of reclaiming and revitalizing the sense of the future and its possibilities. Engaging with such figures as Alain Badiou, Quentin Meillassoux, Ernesto Laclau, Slavoj Zizek, and Fredric Jameson, Glyn Daly articulates the distinctness of speculative philosophy and draws its implications for new debates in areas of science, politics, capitalism, ideology, ethics, and the event." -- Publisher's description.

Since its inception in the late 2000s, supporters of Quentin Meillassoux tended to oppose the movement he founded, speculative materialism, to Derrida and the Derridean community. The arc of Meillassoux's later publications, however, did not support that opposition, especially when it became clear that he neither dismissed correlationism nor set aside literary concerns. These approaches might not be as incompatible as has been supposed. Still, if any affinity is to be established, a first need is to reassess the core (...) of Meillassoux's argument in After Finitude, which has continued to influence his publications. In this article, I attempt not merely to comment upon Meillassoux's argument, but to justify it from within, and so to demonstrate its logic. Then, using a method of re-reading that will be familiar to many, I will attempt to show how that logic reveals speculative materialism and Derridean concerns to be better treated as logical affiliates. Doing so will not presuppose agreement, but will set the stage for more thorough comparisons in future. (shrink)

Peirce promised but never delivered a theoretical system called "speculative rhetoric," therefore explication is synthesized from throughout his writings. bypassing nearly everything akin to standard rhetorical theory, he thinks of it as the "power of appealing to a mind" defined strictly in terms of logical processes. these "formal conditions of symbolic force" fall into two operations: "methodeutic" is an alternating inductive/deductive process beginning with imagined ideational relationships and ending with a specific claim or idea; "assertiveness" is a conjoining of (...) images ("icons") which, when directed upon the attention ("indexed"), provides compulsiveness to the idea.
