This third volume in the definitive edition of Dewey's early work opens with his tribute to George Sylvester Morris, the former teacher who had brought Dewey to the University of Michigan. Morris's death in 1889 left vacant the Department of Philosophy chairmanship and led to Dewey's returning to fill that post after a year's stay at Minnesota. Appearing here, among all his writings from 1889 through 1892, are Dewey's earliest comprehensive statements on logic and his first book on (...) ethics. Dewey's marked copy of the galley-proof for his important article The Present Position of Logical Theory, recently discovered among the papers of the Open Court Publishing Company, is used as the basis for the text, making available for the first time his final changes and corrections. The textual studies that make The Early Works unique among American philosophical editions are reported in detail. One of these, A Note on Applied Psychology, documents the fact that Dewey did not co-author this book frequently attributed to him. Six brief unsigned articles written in 1891 for a University of Michigan student publication, the Inlander, have been identified as Dewey's and are also included in this volume. In both style and content, these articles reflect Dewey's conviction that philosophy should be used as a means of illuminating the contemporary scene; thus they add a new dimension to present knowledge of his early writing.

Jean-Paul Sartre’s early phenomenological texts reveal the complexity of his relationship to Edmund Husserl. Deeply indebted to phenomenology’s method as well as its substance, Sartre nonetheless confronted Husserl’s transcendental turn from Ideas onward. Although numerous studies have focused on Sartre’s points of contention with Husserl, drawing attention to his departure from Husserlian phenomenology, scholars have rarely examined the way in which Sartre engaged and responded to the early Husserl, particularly to his discussions of intentionality, consciousness, and self in (...) Logical Investigations. This essay focuses on Sartre’s critical response to Logical Investigations, arguing that Husserl’s understanding of these three notions shapes and informs Sartre’s own approach to them in The Transcendence of the Ego, “Intentionality: A Fundamental Idea of Husserl’s Phenomenology”, and Being and Nothingness. By carefully reading Sartre side by side with Husserl, this essay arti... (shrink)

ABSTRACT This paper offers an account of the early career of Martha Kneale, née Hurst, and of the five papers she published between 1934 and 1950. One on metaphysical and logical necessity, from 1938, is particularly interesting. In it she considers the metaphysics of time and offers an explanation of ‘the necessity of the past’, which has some resemblance to Kripke’s ideas about metaphysical necessities, in that it assigns an important role to experience in how we come to know (...) them. But Kneale’s view is very different from Kripke’s, depending not on doctrines about rigid designation but rather on recognition of the failure of the atomist/empiricist account of ‘simple’ and ‘complex’ concepts. That account cannot deal with such things as the relations of the determinates of a determinable like colour. A plausible corollary of this, which Kneale exploits, is that some of our experience reveals to us that there are phenomena which are intrinsically complex in having multiple distinguishable aspects, but where those aspects are inseparable. Other of the papers show Kneale to have been pursuing interesting lines of thought about McTaggart’s argument against the reality of time and on the mind-body problem. (shrink)

In Logic, Watts address proper thinking under the four basic functions of the human mind: perception, judgment, reasoning, and disposition. In part one, Watts addresses human perception, the cultivation of ideas, and how we associate them with words. In part two, Watts treats human judgment and its ability to construct various kinds of propositions, while giving guidance for avoiding the formation of bad judgments. Part three covers our ability to reason, giving instruction on the use of syllogisms for constructing (...) a good argument. Part four discusses the mind's disposition as a method of arranging our thoughts for better understanding and memory. (shrink)

The price of Bitcoin is once more soaring. From early October 2020 to early January 2021, the price of a single Bitcoin token went from roughly $10,000 to nearly $65,000, reinspiring the hopes of the crypto-faithful in the inevitability of a future beyond centralized banking and leaving the rest to dread the jargon of computational libertarianism. The speculative betting driving this recent price action, however, belies a more rudimentary and overlooked shift in the digital economy signaled by cryptocurrencies (...) and Bitcoin in particular. Unlike an earlier industrial logic that sought to reduce heat loss and improve efficiency to maximize surplus value, Bitcoin’s proof-of-work system shifts the basis of value production from efficiency to inefficiency. Moreover, it does so by using a cryptographic algorithm whose purpose is to destroy the meaning of its inputs. Through an exploration of Bitcoin’s proof-of-work technics and its inversion of traditional models of value extraction, the text argues that Bitcoin reveals a profound transformation in the nature of surplus represented by computational capitalism.

This is the sequel to Logic. A disciplined mind is one of the most conspicuously missing things in our society. This book can help alleviate that malady. The subtitle of this book is, "Communication of useful knowledge in religion, in the sciences, and in common life." This is a lithograph of an 1833 edition printed in London which also contains "A Discourse on the Education of Children and Youth.".

Antoine Arnauld and Pierre Nicole were philosophers and theologians associated with Port-Royal Abbey, a centre of the Catholic Jansenist movement in seventeenth-century France. Their enormously influential Logic or the Art of Thinking, which went through five editions in their lifetimes, treats topics in logic, language, theory of knowledge and metaphysics, and also articulates the response of 'heretical' Jansenist Catholicism to orthodox Catholic and Protestant views on grace, free will and the sacraments. In attempting to combine the categorical theory (...) of the proposition with a Cartesian account of knowledge, their Logic represents the classical view of judgment which inspired the modern transformation in logic and semantic theory by Frege, Russell, Wittgenstein and recent philosophers. This edition presents a new translation of the text, together with a historical introduction and suggestions for further reading. (shrink)

This monograph explores the logical systems of early logicians in the Arabic tradition from a theoretical perspective, providing a complete panorama of early Arabic logic and centering it within an expansive historical context. By thoroughly examining the writings of the first Arabic logicians, al-Fārābī, Avicenna and Averroes, the author analyzes their respective theories, discusses their relationship to the syllogistics of Aristotle and his followers, and measures their influence on later logical systems. Beginning with an introduction to the (...) writings of the most prominent Arabic logicians, the author scrutinizes these works to determine their categorical logic, as well as their modal and hypothetical logics. Where most other studies written on this subject focus on the Arabic logicians’ epistemology, metaphysics, and theology, this volume takes a unique approach by focusing on the actual technical aspects and features of their logics. The author then moves on to examine the original texts as closely as possible and employs the symbolism of modern propositional, predicate, and modal logics, rendering the arguments of each logician clearly and precisely while clarifying the theories themselves in order to determine the differences between the Arabic logicians’ systems and those of Aristotle. By providing a detailed examination of theories that are still not very well-known in Western countries, the author is able to assess the improvements that can be found in the Arabic writings, and to situate Arabic logic within the breadth of the history of logic. This unique study will appeal mainly to historians of logic, logicians, and philosophers who seek a better understanding of the Arabic tradition. It also will be of interest to modern logicians who wish to delve into the historical aspects and progression of their discipline. Furthermore, this book will serve as a valuable resource for graduate students who wish to complement their general knowledge of Arabic culture, logic, and sciences. (shrink)

This book sets out for the first time in English and in the terms of modern logic the semantics of the Port Royal Logic of Antoine Arnauld and Pierre Nicole, perhaps the most influential logic book in the 17th and 18th centuries. Its goal is to explain how the Logic reworks the foundation of pre-Cartesian logic so as to make it compatible with Descartes' metaphysics. The Logic's authors forged a new theory of reference based (...) on the medieval notion of objective being, which is essentially the modern notion of intentional content. Indeed, the book's central aim is to detail how the Logic reoriented semantics so that it centered on the notion of intentional content. This content, which the Logic calls comprehension, consists of an idea's defining modes. Mechanisms are defined in terms of comprehension that rework earlier explanations of central notions like conceptual inclusion, signification, abstraction, idea restriction, sensation, and most importantly within the Logic's metatheory, the concept of idea-extension, which is a new technical concept coined by the Logic. Although Descartes is famous for rejecting "Aristotelianism," he says virtually nothing about technical concepts in logic. His followers fill the gap. By putting to use the doctrine of objective being, which had been a relatively minor part of medieval logic, they preserve more central semantic doctrines, especially a correspondence theory of truth. A recurring theme of the book is the degree to which the Logic hews to medieval theory. This interpretation is at odds with what has become a standard reading among French scholars according to which this 16th-century work should be understood as rejecting earlier logic along with Aristotelian metaphysics, and as putting in its place structures more like those of 19th-century class theory.

Description: Ancient Indian logic by itself is a very vast subject. The ancient Sanskrit term nyaya which was first used in a different or in a much more general sense, was later specifically applied to the Nyaya school. The physics and physiology and psychology of the Nyaya doctrine are not specifically its own, being from the first indistinguishable from those of its sister Sastra, the Vaisesika. What characterizes it specifically is the development of the nyaya or five-membered method of (...) demonstration and its insistence on the four sources of knowledge, corresponding to the first four members of its demonstrative formula, or 'Syllogism.' The importance of Nyaya is in its doctrine of the pramanas, or sources of proof, and in its formulation of the nyaya, or method of demonstration. Indian Logic in its Early Schools by H.N. Randle is an interpretation of Indian logical theory in its historical development based on the study of original texts wherever reference to Nyaya as a method of logic has been made, and thus, covers a very wide field of Indian philosophy. An indispensable work for students of Indian philosophy, it is especially important for those who are interested in Nyayadarsana in its relation to the early logic of other schools. (shrink)

Ibn Wasil (d. 1298), perhaps better known today as a historian and an emissary to the court of King Manfred in southern Italy, was also an eminent logician. The present work is a critical edition of his main work in the field, a commentary on his teacher Khunaji's (d. 1248) handbook al-Jumal. The work helped consolidate the logic of the "later scholars" (such as Khunaji). It also shows that commentators did much more than merely explain the original work and (...) instead regularly discussed and assessed received views. Ibn Wasil's work was an influential contribution to a particularly dynamic chapter in the history of Arabic logic. (shrink)

A common analysis of Edmund Husserl’s early works on the philosophy of logic and mathematics presents these writings as the result of a combination of two distinct strands of influence: on the one hand a mathematical influence due to his teachers is Berlin, such as Karl Weierstrass, and on the other hand a philosophical influence due to his later studies in Vienna with Franz Brentano. However, the formative influences on Husserl’s early philosophy cannot be so cleanly (...) separated into a philosophical and a mathematical pathway. Growing evidence indicates that a Brentanist philosophy of mathematics was already in place before Husserl. Rather than an original combination at the confluence of two different streams, his early writings represent an elaboration of topics and problems that were already being discussed in the School of Brentano within a pre-existing framework. The traditional account understandably neglects Brentano’s own work on the philosophy of mathematics and logic, which can be found mostly in his unpublished manuscripts and lectures, and various works by Brentano’s students on the philosophy of mathematics which have only recently emerged from obscurity. Husserl’s early works must be correctly placed in this preceding context in order to be fully understood and correctly assessed. (shrink)

In 1931 Kurt Gödel published his incompleteness results, and some years later Church and Turing showed that the decision problem for certain systems of symbolic logic has a negative solution. However, already in 1921 the young logician Emil Post worked on similar problems which resulted in what he called an “anticipation” of these results. For several reasons though he did not submit these results to a journal until 1941. This failure ‘to be the first’, did not discourage him: his (...) contributions to mathematical logic and its foundations should not be underestimated. It is the purpose of this article to show that an interest in the early work of Emil Post should be motivated not only by this historical fact, but also by the fact that Post’s approach and method differs substantially from those offered by Gödel, Turing and Church. In this paper it will be shown how this method evolved in his early work and how it finally led him to his results. (shrink)

John Dewey is celebrated for his work in the philosophy of education and acknowledged as a leading proponent of American pragmatism. His philosophy of logic, on the other hand, is largely unheard of. In Dewey's New Logic, Burke analyzes portions of the debate between Dewey and Bertrand Russell that followed the 1938 publication of Dewey's Logic: The Theory of Inquiry. Burke shows how Russell failed to understand Dewey, and how Dewey's philosophy of logic is centrally relevant (...) to contemporary developments in philosophy and cognitive science. Burke demonstrates that Russell misunderstood crucial aspects of Dewey's theory and contends that logic today, having progressed well beyond Russell's early views, is approaching Dewey's broader perspective. -/- "[This] book should be of substantial interest not only to Dewey scholars and other historians of twentieth-century philosophy, but also to devotees of situation theory, formal semantics, philosophy of mind, cognitive science, and Artificial Intelligence."--Georges Dicker, Transactions of the C.S. Peirce Society "No scholar, thus far, has offered such a sophisticated and detailed version of central themes and contentions in Dewey's Logic . This is a pathbreaking study."--John J.

The emergence of analytic philosophy has often been seen as inaugurating a linguistic turn in philosophy, a turn with profound anti-metaphysical implications. Metaphysics and epistemology, on this view, were replaced by logic and philosophy of language as forming the basis of philosophy. But if we look at the work of the four founders of analytic philosophy, Frege, Russell, Moore and Wittgenstein, we find metaphysical conceptions at the heart of their endeavours. Frege, for example, regarded numbers and the truth-values as (...) logical objects, and the ontological distinction between concept and object was fundamental to his philosophy. Both Russell and Moore in their early work developed a realist view of propositions, and even when Russell abandoned the metaphysics of propositions in his later work, this was simply replaced by a metaphysics of facts. Wittgenstein, too, in the Tractatus, articulated a raft of theses that seem paradigmatically metaphysical, though their precise status has been controversial. In this paper I outline some of the key metaphysical conceptions of Frege, Russell, Moore and the early Wittgenstein, and explore the connections with their logical views, taking as my main example the problem of relational propositions. I end by addressing the question of the status of the metaphysical statements that Frege and Wittgenstein, in particular, found themselves making. (shrink)

This paper investigates mathematical ideas found in a Jaina non-mathematical text, by which I mean a work not dedicated to mathematics as a separate scholarly discipline. The Aṇuogaddārāiṃ, a Prakrit text from the Śvetāmbara Āgamas, explains the methods a Jaina monk should use in investigating a scriptural text. This work shows a remarkable ability to deal with numerical concepts and quantitative descriptions of all kinds. I shall often compare its mathematical content with texts from different Sanskrit bodies of (...) knowledge. This paper demonstrates that the Aṇuogaddārāiṃ, as well as presenting a wealth of mathematical information, expounds a Jaina theory of numbers that has been so far disregarded by historiography. In order to understand this formulation, I shall propose an analytical-interpretative model to then improve the English translation by Hanaki 1970. In Jainism, the knowledge of the true nature of the universe was a requisite to progressing towards a full awareness of the human condition and hence towards the path of liberation. Numerical data and detailed calculations provide minute descriptions of the universe and matters related to karma and liberation. I shall argue that the Aṇuogaddārāiṃ testifies that mathematics was a perfect, functional instrument for representing Jaina cosmological and soteriological models. (shrink)

This book makes available to the English reader nearly all of the shorter philosophical works, published or unpublished, that Husserl produced on the way to the phenomenological breakthrough recorded in his Logical Investigations of 1900-1901. Here one sees Husserl's method emerging step by step, and such crucial substantive conclusions as that concerning the nature of Ideal entities and the status the intentional `relation' and its `objects'. Husserl's literary encounters with many of the leading thinkers of his day illuminates both (...) the context and the content of his thought. Many of the groundbreaking analyses provided in these texts were never again to be given the thorough expositions found in these early writings. Early Writings in the Philosophy of Logic and Mathematics is essential reading for students of Husserl and all those who enquire into the nature of mathematical and logical knowledge. (shrink)
