When the original Dutch version of this book was presented in 1971 to the University of Leiden as a thesis for the Doctorate in philosophy, I was prevented by the academic mores of that university from expressing my sincere thanks to three members of the Philosophical Faculty for their support of and interest in my pursuits. I take the liberty of doing so now, two and a half years later. First and foremost I want to thank Professor G. (...) Nuchelmans warmly for his expert guidance of my research. A number of my most im portant sources were brought to my attention by him. During the whole process of composing this book his criticism and encouragement were carried out in a truly academic spirit. He thereby provided working conditions that are a sine qua non for every author who is attempting to approach controversial matters in a scientific manner, conditions which, however, were not easily available at that time. In a later phase I also came into contact with Professors L. M. de Rijk and J. B. Ubbink, with both of whom I had highly stimulating discussions and exchanges of ideas. The present edition contains some entirely new sections, viz. 1-9, IV-29, V-9, V-20, VII-14 (iii), (iv), VII-17 (i), VIII-22, IX-17, IX-19, X-9 and XI-8. Section X-9 was inspired by a remark made by Professor A. (shrink)

Hao Wang was one of the few confidants of the great mathematician and logician Kurt Gödel. _A Logical Journey_ is a continuation of Wang's _Reflections on Gödel_ and also elaborates on discussions contained in _From Mathematics to Philosophy_. A decade in preparation, it contains important and unfamiliar insights into Gödel's views on a wide range of issues, from Platonism and the nature of logic, to minds and machines, the existence of God, and positivism and phenomenology. The impact of Gödel's (...) theorem on twentieth-century thought is on par with that of Einstein's theory of relativity, Heisenberg's uncertainty principle, or Keynesian economics. These previously unpublished intimate and informal conversations, however, bring to light and amplify Gödel's other major contributions to logic and philosophy. They reveal that there is much more in Gödel's philosophy of mathematics than is commonly believed, and more in his philosophy than his philosophy of mathematics. Wang writes that "it is even possible that his quite informal and loosely structured conversations with me, which I am freely using in this book, will turn out to be the fullest existing expression of the diverse components of his inadequately articulated general philosophy." The first two chapters are devoted to Gödel's life and mental development. In the chapters that follow, Wang illustrates the quest for overarching solutions and grand unifications of knowledge and action in Gödel's written speculations on God and an afterlife. He gives the background and a chronological summary of the conversations, considers Gödel's comments on philosophies and philosophers, and his attempt to demonstrate the superiority of the mind's power over brains and machines. Three chapters are tied together by what Wang perceives to be Gödel's governing ideal of philosophy: an exact theory in which mathematics and Newtonian physics serve as a model for philosophy or metaphysics. Finally, in an epilog Wang sketches his own approach to philosophy in contrast to his interpretation of Gödel's outlook. (shrink)

Kelly suggested that it was useful to consider anyone as functioning as a scientist, in the business of applying theories, making hypotheses and predictions and testing them out in the practice of everyday life. One of Charles Peirce’s major contributions was to develop the disciplines of logic and the philosophy of science. We can deepen and enrich our understanding of Kelly’s vision by looking at what Peirce has to say about the process of science. For Peirce, the essence (...) of science was the application of the laws of inference. He developed a much broader concept of logic, elaborating the processes of deduction and induction and adding to these the logic of hypothetical inference, or ‘abduction’, even as Kelly broadened it further in his “departure from classical logic”. Examining the implications of these three forms of inference allows us to elaborate the dynamics involved in the process of construing, ordinacy and the cycles of experience, creativity and decision making. This is the second of a three part series examining the relationship between the work of Peirce and Kelly. The third will include a look at phenomenology, bipolarity, the self, dialogical process and sociological considerations. (shrink)

In a career that spans 60 years so far, W.W. Tait has made many highly influential contributions to logic, the philosophy of mathematics, and their history. The present collection of new essays - contributed by former students, colleagues, and friends - is a Festschrift, i.e., a celebration of his life and work. The essays address a variety of themes prominent in his work or related to it. The collection starts with an introduction in which Tait's contributions are (...) sketched and put into context. The eleven essays that follow are arranged in three parts: Part I. Proof Theory and its History; Part II. Logic and Philosophy of Mathematics; and Part III. History of Logic and Philosophy of Mathematics. Each of the essays contributes substantially to one or several of these areas. The authors included are: Steve Awodey, Solomon Feferman, Michael Friedman, Warren Goldfarb, Geoffrey Hellman, William Howard, Stephen Menn, Rebecca Morris, Charles Parsons, Erich Reck, Thomas Ricketts, and Wilfried Sieg. The editor, Erich H. Reck is Professor of Philosophy at the University of California at Riverside. (shrink)

Bruno Liebrucks hat eine eigenständige, an Vico, Herder, Hamann, Humboldt und Cassirer anknüpfende Philosophie von der Sprache her“ entwickelt, welche Sprache als Medium der Welterschließung begreift. Zu dieser gelangt er durch eine fundamentalphilosophische Auseinandersetzung mit jenen drei Revolutionierungen im Denken des Denkens, die mit den Namen Platon, Kant und Hegel verknüpft sind. Die Beiträge des Bandes gehen diesen „Revolutionen der Denkart“ nach und entfalten grundlegende Perspektiven, die sich von Liebrucks her für das Verständnis der Logik, der Philosophischen Anthropologie, der Ethik (...) und Politischen Philosophie, der Kunstphilosophie sowie der Philosophischen Theologie ergeben. Die Autoren sind: Leo Dorner, Max Gottschlich, Thomas Sören Hoffmann, Klaus Honrath, Simone Liedtke, Theodoros Penolidis, Brigitte Scheer, Werner Schmitt, Josef Simon, Maria Woschnak, Werner Woschnak und Fritz Zimbrich.

This paper outlines three broad ways one might think about logical correctness: the Realist approach, the One-Language approach and my own Neo-Carnapian view. Although the realist and one-language views have dominated the philosophy of logic in recent years, I argue against them, favouring of the Neo-Carnapian approach.

_Contributions to Law, Philosophy and Ecology: Exploring Re-Embodiments_ is a preliminary contribution to the establishment of re-embodiments as a theoretical strand within legal and ecological theory and philosophy. Re-embodiments are all those contemporary practices and processes that exceed the epistemic horizon of modernity. As such, they offer a plurality of alternative modes of theory and practice that seek to counteract the ecocidal tendencies of the Anthropocene. The collection is comprised of eleven contributions approaching re-embodiments from a multiplicity (...) of fields, including legal theory, eco-philosophy, eco-feminism and anthropology. The contributions are organized in three parts, ‘Beyond Modernity, ‘The Sacred Dimension’ and ‘The Legal Dimension’. The collection is opened by a comprehensive introduction that situates re-embodiments in theoretical context. Whilst closely bound with embodiment and new materialist theory, this book_ _contributes a unique voice that echoes diverse political processes contemporaneous to our times. Written in an elegant and accessible language, the book will appeal to undergraduates, postgraduates and established scholars alike seeking to understand and take re-embodiments further, both politically and theoretically.

This article argues that philosophical hermeneutics, despite its onto-logical character, can inform higher education teaching in a meaningful way. After discussing theoretical aspects of philosophical her-meneutics, focus will turn to pre-understandings and historically effected consciousness. These concepts will lead to hermeneutics’s transformative nature, with the notion of openness serving as a com-mon thread. The review of three further concepts of philosophical hermeneutics—hermeneutical experience, authentic dialogue, and Bildung—will provide insight into openness as a vanishing point without being a culmination. (...) Parallels to Mezirow’s method of trans-formative learning will be drawn and the concept of Bildung, central to philosophical hermeneutics, will be considered through the Hum-boldtian lens to better extract its practical implications, which lay beyond Gadamer’s theoretical focus. Finally, the last section will cement the applicative intent of the article by presenting concrete teaching practices that ????low from philosophical hermeneutics. (shrink)

Dorothy Edgington’s work has been at the centre of a range of ongoing debates in philosophical logic, philosophy of mind and language, metaphysics, and epistemology. This work has focused, although by no means exclusively, on the overlapping areas of conditionals, probability, and paradox. In what follows, I briefly sketch some themes from these three areas relevant to Dorothy’s work, highlighting how some of Dorothy’s work and some of the contributions of this volume fit in to these debates.

The article reconstructs Jean Cavaillès’s polemical engagement with Edmund Husserl’s phenomenological philosophy of mathematics. I argue that Cavaillès’s encounter with Husserl clarifies the scope and ambition of Cavaillès’s philosophy of the concept by identifying three interrelated epistemological problems in Husserl’s phenomenological method: (1) Cavaillès claims that Husserl denies a proper content to mathematics by reducing mathematics to logic. (2) This reduction obliges Husserl, in turn, to mischaracterize the significance of the history of mathematics for the philosophy (...) of mathematics. (3) Finally, Husserl’s phenomenology distorts the nature of mathematical experience. Accordingly, Cavaillès’s philosophy of mathematics is premised on a threefold affirmation designed to overcome these inadequacies. Cavaillès claims that mathematics is an autonomous field of conceptual production that cannot be reduced to logical, psychological, or phenomenological descriptions of conceptual genesis. Two important corollaries follow: the history of mathematics must guide the philosophy of mathematics, and mathematical experience itself must be described according to the mechanisms of a novel theory of mathematical abstraction. In what follows, I demonstrate that Cavaillès’s encounter with Husserl does not merely describe a polemical engagement with a rival philosophical position; it allows us to reconstruct Cavaillès’s own highly original contributions to the philosophy of mathematics.

The highly sophisticated techniques of modern engineering are normally conceived of in practical terms. Corresponding to the instrumental function of technology, they are designed to direct the forces of nature according to human purposes. Yet, as soon as the realm of mere skills is exceeded, the intended useful results can only be achieved through planned and preconceived action processes involving the deliberately considered application of well designed tools and devices. This is to say that in all complex cases theoretical reasoning (...) becomes an indispensable means to accomplish the pragmatic technological aims. Hence the abstracting from the actual concrete function of technology opens the way to concentrate attention on the general conceptual framework involved. If this approach is adopted the relevant knowledge and the procedures applied clearly exhibit a logic of their own. This point of view leads to a methodological and even an epistemological analysis of the theoretical structure and the specific methods of procedure characteristic of modern technology. Investigations of this kind, that can be described as belonging to an ana lytical philosophy of technology, form the topic of this anthology. The type of research in question here is closely akin to that of the philosophy of science. But it is an astonishing fact that the commonly accepted and carefully investigated philosophy of science has not yet found its counterpart in an established philosophy of technology. (shrink)

This is the collection of essays presented to Bochenski on his 60th birthday, and it contains, as a mirror of Bochenski's own work, a broad spectrum of studies ranging from formal logic and history of logic, to the philosophy of logic and language, and to the methodology of explanation in Greek philosophy. Of the seventeen articles, these are some of the more important to the reviewer: "Betrachtungen zum Sequenzen Kalkül" by Paul Bernays, which is an extensive study of (...) Gentzen-type formulations of logic; "Remarks on Formal Deduction," H. B. Curry, a further discussion of sequenzen-logics; "Marginalia on Gentzen's Sequenzen Kalkül" by Hughes Leblanc; "Method and Logic in Presocratic Explanation," Jerry Stannard; "On the Logic of Preference and Choice," H. S. Houthakker, a suggestive presentation of decision and utility theory in logical form; "Leibniz's Law in Belief Contexts," Chisholm; "On Ontology and the Province of Logic," R. M. Martin; and "N. A. Vasilev and the Development of Many-valued Logics," G. L. Kline, an important addition to the history of logic. Other contributors are: Storrs McCall, Albert Menne, E. W. Beth, Benson Mates, Ivo Thomas, J. F. Staal, F. R. Barbò, A.-T. Tymieniecka, and N. M. Luyten. There is a bibliography of Bochenski's writings through 1962.—P. J. M. (shrink)

Papers presented at a three-day National Symposium on Christian Contribution to Indian Philosophy from 1st to 3rd March 1994 and jointly organized by Indian Council of Philosophical Research and Satya Nilayam Research Institute.

This volume is a collection of the Lullian contributions to the 2012 Congress of the Societe Internationale pour l'Etude de la Philosophie Medievale (SIEPM), held in Freising, Germany, 20-25 August. The Lullian Opera constitute a philosophical mirror of the medieval tradition. The questions and interests of medieval masters played a role in the Renaissance and Early Modern period through the Lullian Art. The three parts of this volume-Knowledge, Contemplation and Lullism- are intended to show that influence, collecting the (...) contributions of well-known specialists on the Lullian works, conceived of as Opera philosophica, in different areas such as geometry, logic, methodology, or Early Modern law. The results of Lullian studies in the past 20th century and the revival of Lullian discussions at present also hold an important place. The Raimundus-Lullus-Institut in Freiburg supports this edition, and in the introduction its members place the volume in the great tradition of Lullian studies. The celebration of a Lullian meeting devoted to the relationship between medieval philosophy and the Lullian Opus at the 2012 SIEPM Congress, the recent constitution of a Lullian Section by the SIEPM-Bureau to develop projects about Llull's works as a vehicle of medieval philosophical concerns and the history of its reception, and the results collected in this volume, are a good example of the increasing relevance of Llull-studies today.

The change of medieval philosophy, known to have taken place in the 14th century, is accompanied by a new and extensive application of terminist logic and by a growing importance of the university of Oxford. This essay asks the question whether this development can be explained as a development of a specific English tradition within medieval logic. In the first part of the paper it is briefly shown that a certain discontinuity can be observed in the most important continental (...) intellectual centers; the 'sociological' conditions which make possible such distinct local traditions within the general development of medieval scholasticism are considered shortly. The second and larger part of the paper is a census of the English contribution to logic before Ockham, ordered according to the various literary genres: Summulae, Syncategoremata/sophismata, Grammar, Commentaries on the Organon. This census tends to prove that terminist logic had a continuous tradition in Oxford, a fact which may account for the preponderance of Oxford logic in the early 14th century. (shrink)

Adolf Reinach (1883-1917) is most often remembered for his role as a teacher of phenomenology or as a philosopher of law, yet the range of subjects covered in his surviving published and unpublished works is diverse. As scholars such as Kimberley Baltzer-Jaray have argued, Reinach's contributions to philosophy, and in particular his influence on the early phenomena logical movement, have been underestimated in the past. It is of both historical and philosophical importance, therefore, to identify and recognise (...) the contributions that Reinach made across the many fields his works touch upon, including that of ethics. This thesis argues that Reinach made a number of significant contributions towards the development of early phenomenological ethics, and although his works contain neither a complete nor a comprehensive systematic theory of ethics, this is no reason to overlook or dismiss the importance of his work in this field . The thesis demonstrates that Reinach's works on ethics were original; that they influenced other early phenomenologists in the development of their ethical theories; and, ultimately, that they were and remain valuable additions to the field, discussing value-theory, the problem ofnormativity, motivation, freedom and responsibility, and more. This thesis comprises two parts. Part one examines and assesses Reinach's contribution against his immediate philosophical background incorporating a discussion of how Reinach's works on ethics fit into his body of work as well in relation to other contemporary philosophers (e.g., Brentano, Husserl, Scheler, Stein) who advanced the development of early phenomenological ethics. To support the interpretation, part two of the thesis contains appendices of three relevant extracts from Reinach 's published and unpublished works, translated for the first time into English (with original German text supplied). These translations are also intended to be ofvalue in making Reinach's works on ethics more accessible to English-speaking scholarship in the future. (shrink)

In this paper I attempt to capture the essence of Nelson Pike’s contribution to the philosophy of religion. My summary of his insights will revolve around three general topics: omniscience (and in particular its relation to human freedom), omnipotence (and in particular its relation to the existence of human suffering), and mysticism (with a focus on the question of whether and in what sense mystic visions can be sources of knowledge). Although the details vary in interesting ways, his (...) work on these topics largely consists of recognizing an important challenge to the viability of the relevant doctrine or framework, sharpening that challenge by presenting it in a more forceful way, and then offering and assessing potential responses. Pike’s writings are characterized by exemplary rigor and relentless clarity, and together they constitute a rich (and under-appreciated) source of insight. (shrink)

This volume presents the proceedings from the Eleventh Brazilian Logic Conference on Mathematical Logic held by the Brazilian Logic Society in Salvador, Bahia, Brazil. The conference and the volume are dedicated to the memory of professor Mario Tourasse Teixeira, an educator and researcher who contributed to the formation of several generations of Brazilian logicians. Contributions were made from leading Brazilian logicians and their Latin-American and European colleagues. All papers were selected by a careful refereeing processs and were revised and (...) updated by their authors for publication in this volume. There are three sections: Advances in Logic, Advances in Theoretical Computer Science, and Advances in Philosophical Logic. Well-known specialists present original research on several aspects of model theory, proof theory, algebraic logic, category theory, connections between logic and computer science, and topics of philosophical logic of current interest. Topics interweave proof-theoretical, semantical, foundational, and philosophical aspects with algorithmic and algebraic views, offering lively high-level research results. (shrink)

I refer to Charles Dorn's (...) Mind in Art, my book Art and Cognition, and Elliot Eisner's The Arts and the Creation of Mind, with the publication of the latter providing the occasion for this article.1 Each of these texts makes its case for the arts in education on somewhat similar grounds. All three share the view that the creation and understanding of works of art, though endowed with feeling and emotion, are nevertheless cognitive endeavors. But why have so many books appeared on the topic of cognition at this time? To answer this question it becomes necessary to describe the changes in our understanding of cognition and the problems these have created for the arts in education.Once cognition was the term used to designate propositional thinking with verbal and numerical symbols, whereas the current sense of the term embraces all forms of thought including mental images obtained through perception. In short it includes all forms of sentience by which the human organism comes to know itself and its environment. This change was to have a major impact upon curriculum reform initiatives in all studies but it was to have a revolutionary impact upon education in the arts for reasons explained later in this essay. However, an adequate story of cognition in the arts cannot be told without a discussion of Eisner's contributions to this discourse. The Waning of Behaviorism For the first half of the twentieth century the psychology that dominated educational practice was behaviorism. Its proponents included psychologists like Edward L. Thorndike, James B. Watson, and B.F. Skinner.2 Each strove to create a science of psychology that would match the rigor of physics or chemistry, where causes in relation to effects would be carefully observed and measured, making the explanation, prediction, and control of phenomena possible, especially those behaviors that fall under the control of the classroom teacher. The formation of connections called stimulus-response (S-R) bonds had become the molar unit to explain learning, much [End Page 71] like the way that differences in the structure of the atom was used to explain the behavior of the chemical elements of the Periodic Table. This bond between environmental stimuli and the organism's response was seen as the elementary unit of behavior while the IQ had become its measure. Invisible notions like mind and imagination were banished to metaphysical philosophy, outside the legitimate bounds of science.Though behaviorists never denied the existence of higher order thinking that is, abstract, sense-free thinking as found in pure mathematics, they were unable to explain how these human capacities emerge through the accumulation of such rudimentary stimulus-response events. Nevertheless, they recognized that humans do have a capacity for thinking that relies heavily upon symbols like words, numbers and the like. Moreover, certain subjects that require reason and logic, like math and theoretical physics, would be inconceivable without such symbols and the rules by which these are manipulated. By contrast it was assumed that the arts, which relied on sensory images, either did not employ this type of propositional thought, or did so to a far lesser degree. Thus the arts could be dispatched to the noncognitive or affective domains with little or no reduction in the learner's cognitive capacities. Indeed, these noncognitive realms, which gave play to feelings and emotions, were often seen as inimical to the acquisition of rational powers of thought. Intellectual power as it was then understood, required that feelings and emotions be brought under the control of reason.As long as behaviorism served as the dominant paradigm, the school curriculum could be divided into two or three broad divisions...

This volume has two primary aims: to trace the traditions and changes in methods, concepts, and ideas that brought forth the logical empiricists’ philosophy of physics and to present and analyze the logical empiricists’ various and occasionally contrary ideas about the physical sciences and their philosophical relevance. These original chapters discuss these developments in their original contexts and social and institutional environments, thus showing the various fruitful conceptions and philosophies behind the history of 20th-century philosophy of (...) science. Logical Empiricism and the Natural Sciences is divided into three thematic sections. Part I surveys the influences on logical empiricism’s philosophy of science and physics. It features chapters on Maxwell’s role in the worldview of logical empiricism, on Reichenbach’s account of objectivity, on the impact of Poincaré on Neurath’s early views on scientific method, Frank’s exchanges with Einstein about philosophy of physics, and on the forgotten role of Kurt Grelling. Part II focuses on specific physical theories, including Carnap’s and Reichenbach’s positions on Einstein’s theory of general relativity, Reichenbach’s critique of unified field theory, and the logical empiricists’ reactions to quantum mechanics. The third and final group of chapters widens the scope to philosophy of science and physics in general. It includes contributions on von Mises’ frequentism; Frank’s account of concept formation and confirmation; and the interrelations between Nagel’s, Feigl’s, and Hempel’s versions of logical empiricism.

Samuel Butler is usually remembered for Erewhon, widely considered among the best English satires. He also contributed to philosophical biology in works that collectively compose the nineteenth century's finest statement of the evolutionary argument associated with the name of Lamarck. In writing on evolution, Butler was not presenting science for a popular audience but deliberately intervening in the scientific argument about Darwinism. Surprised by the success of his first venture in philosophical biology, Life and Habit, Butler committed himself to the (...) project of developing an alternative to Darwinism, which he did in three additional volumes, and these are the works canvassed in this “delayed book review.”.

§0. Alonzo Church's contributions to philosophy and to that most philosophical part of logic, intensional logic, are impressive indeed. He wrote relatively few papers actually devoted to specifically philosophical issues, as distinguished from related technical work in logic. Many of his contributions appear in reviews for The Journal of Symbolic Logic, and it can hardly be maintained that one finds there a “philosophical system”. But there occur a clearly articulated and powerful methodology, terse arguments, often of “crushing (...) cogency”, and philosophical observations of the first importance.Many of the less formal philosophical contributions center around questions concerning meaning, but there are important clarifications and insights into matters of the epistemology and ontology of the sciences, especially the formal sciences.1.1. The logistic method. Church's writings on philosophical matters exhibit an unwavering commitment to what he called the “logistic method”. The term did not catch on and now one would just speak of “formalization”. The use of these ideas is now so common and familiar among logicians and logically-oriented philosophers that they are simply taken for granted. But they deserve to be celebrated and re-emphasized, for there are philosophers who seriously underestimate and even consciously reject these techniques. (shrink)

The article features several Polish philosophers and their contributions to world philosophy. Matthew of Kraków wrote the Rationale divinorum operum or the Rationality of Divine Works in which he discussed the philosophy of Plato and Saint Augustine on devil and created views on philosophical anthropology. Andrzej Frycz Modrzewski wrote five books on reformation during the Renaissance. Marcin Śmiglecki was a professor at the Vilnius Academy and wrote books on logic and metaphysics.

My paper is divided into three parts. The first examines the different versions of phenomenology that Husserl used during the Freiburg period, including genetic phenomenology, which is considered, in Experience and Judgment, as the basis for his genealogy of logic. I also examine the doxa-episteme opposition, which is one of the central topics of this book, and I claim that Brentano's epistemic asymmetry between internal and external perception can be considered as a special case of this opposition, which Husserl (...) seeks to overcome. The second part consists in an account of the genesis of the concept of primary content, such as it was first introduced in his Habilitationsschrift in order to replace Brentano's notion of physical phenomenon, to Ideas I where Husserl seems to have abandoned this notion, and replaced it with that of hyle which he conceived in a way similar to that of traditional atomism. The third part shows that the lectures and the working manuscripts of the Freiburg period, including Experience and Judgment, dispel the impression left by Ideas I by providing an original analysis of the dimension of sensory experience. Our starting point is an analysis of the cases of misperception that serve as arguments against Brentano's theory of external perception and whose function here is to uncover several distinctions relating to the modes of consciousness which are directly related to primary contents and to the qualitative dimension of experience. I conclude on the subject of passive syntheses and argue that they refer to a multiplicity of relations that structure phenomenal experience. (shrink)

Popper's writings cover a remarkably wide range of subjects. The spectrum runs from Plato's theory of politics to the foundations of quantum mechanics. Yet even amidst this variety the philosophy of probability occupies a prominent place. David Miller once pointed out to me that more than half of Popper's The Logic of Scientific Discovery is taken up with discussions of probability. I checked this claim using the 1972 6th revised impression of The Logic of Scientific Discovery , and found (...) that of the approximately 450 pages of text, approximately 250 are to do with probability. Thus Miller's claim is amply justified. It seems indeed that the philosophy of probability was one of Popper's favourite subjects, and, as we shall see, Popper certainly enriched the field with several striking innovations. In this area, as in others, Popper held very definite views, and criticized his opponents in no uncertain terms. Popper was an objectivist and anti-Bayesian, and his criticisms were directed against subjectivism and Bayesianism. (shrink)

This article is part of a larger project in which I attempt to show that Western formal logic, from its inception in Aristotle onward, has both been partially constituted by, and partially constitutive of, what has become known as racism. In contrast to this trend, the present article concerns the major philosopher whose contribution to logic has been perhaps the most derided and marginalized, and yet whose character and politics are, from a contemporary perspective, drastically superior—John Stuart Mill. My approach (...) to my core concern will be one of narrowing concentric circles. I will begin with Mill’s occasional political writings that bear on the issue of racism, including “The Negro Question.” From there, the core of the article will explore the political dimensions of Mill’s A System of Logic.

Logic and African Philosophy: Seminal Essays on African Systems of Thought aims to put African intellectual history in perspective, with focus on the subjects of racism, logic, language, and psychology. The volume seeks to fill in the gaps left by the exclusion of African thinkers that are frequent in the curricula of African schools concerning history, sociology, philosophy, and cultural studies. The book is divided into four parts that are preceded by an introduction to link up the essays (...) and emphasize their sociological implications. Part one is comprised of essays that opened the controversy of whether logic can be found in traditional African cultures as well as other matters like the nature of the mind and behavior of African peoples. The essays in part two are centered on the following question: are the laws of thought present in African languages and cultures? Part three brings together essays that sparkle the debate on whether there can be such a thing as African logic, which stems from the discussions in part two. Part four is concerned on the theme of system-building in logic; contributions are written by members of the budding African philosophy movement called the 'Conversational School of Philosophy' based at the University of Calabar, and the main objective of their papers is to formulate systems of African logic.

These considerations suffice to indicate the character of conditional realization as a modal relationship "intermediate" in logical strength between the modalities of conditional necessity and conditional possibility. I now turn to a more detailed examination of the interpretation of this concept.
