In 1934 a most singular event occurred. Two papers were published on a topic that had (apparently) never before been written about, the authors had never been in contact with one another, and they had (apparently) no common intellectual background that would otherwise account for their mutual interest in this topic.1 These two papers formed the basis for a movement in logic which is by now the most common way of teaching elementary logic by far, and indeed is perhaps all (...) that is known in any detail about logic by a number of philosophers (especially in North America). This manner of proceeding in logic is called ‘natural deduction’. And in its own way the instigation of this style of logical proof is as important to the history of logic as the discovery of resolution by Robinson in 1965, or the discovery of the logistical method by Frege in 1879, or even the discovery of the syllogistic by Aristotle in the fourth century BC.

This paper provides a short summary of Mark Bevir, The Logic of the History of Ideas (Cambridge: Cambridge University Press, 1999). Logic stands here as a subset of Wittgenstein’s notion of philosophy as a matter of the grammar of our concepts. It studies the forms of reasoning appropriate to a discipline, rather than the material of that discipline. Hence, the logic of the history of ideas considers the nature of meaning, the way we should justify our knowledge of (...) past meanings, and how we should explain things such as the existence of meanings, the beliefs people held, and conceptual change.

Paperback. The intention of this book is to set forth the history (up to the end ofthe 17th Century) of logical and rhetorical reflections on dilemmaticarguments, i.e. arguments in which from each member of an exhaustivedisjunction of premisses an identical conclusion is drawn. Certain types ofsuch arguments were widely discussed among ancient teachers of rhetoricand, to a lesser extent, by ancient logicians. After a period of relativeneglect in the Middle Ages, there was a remarkable revival during theRenaissance. In (...) the 17th Century, several attempts were made to find theproper logical form of dilemmatic reasonings. In the course of tracingthese developments, special attention is paid to the consequentiamirabilis, a kind of argument in which a conclusion is inferredfrom a premiss that is its direct contradictory.

Across the globe, education has recently been through a major semantic shift, where new notions such as ‘learning’, ‘competences’, ‘projects’ came to replace or complement an older, more established, educational vocabulary. The political approach to education has also evolved, as many authors have underlined, from established national forms of governing to global, transnational forms of governance. These evolutions, often abbreviated to shifts ‘from teaching to learning’ and ‘from governing to governance’ have resonated globally and attracted the attention of researchers. Most (...) sociological accounts of such evolutions attribute them to the development and primacy of a preponderant logic, generally politics/power, culture or the economy. Niklas Luhmann’s systems theory, on which we draw in this article, suggests to start from a different, opposite, premise: not the predominance but instead the lack of any predominant logic characterizes modernity. The functional differentiation of modern society into a multiplicity of—specific yet universal—systems should therefore be the pivotal point that helps make sense of these transformations. We argue that the very coexistence of such systems, their simultaneous and therefore uncoordinated existences, increases the complexity of the social world tremendously and leaves them with an uncertain future. The so-called turns to governance and to learning, we argue, should be understood, respectively, as political and educational attempts to deal with this loss of direction. (shrink)

The aim of this paper is to introduce Wittgenstein’s concept of the form of a language into geometry and to show how it can be used to achieve a better understanding of the development of geometry, from Desargues, Lobachevsky and Beltrami to Cayley, Klein and Poincaré. Thus this essay can be seen as an attempt to rehabilitate the Picture Theory of Meaning, from the Tractatus. Its basic idea is to use Picture Theory to understand the pictures of geometry. I will (...) try to show, that the historical evolution of geometry can be interpreted as the development of the form of its language. This confrontation of the Picture Theory with history of geometry sheds new light also on the ideas of Wittgenstein. (shrink)

Greek, Indian and Arabic Logic marks the initial appearance of the multi-volume Handbook of the History of Logic. Additional volumes will be published when ready, rather than in strict chronological order. Soon to appear are The Rise of Modern Logic: From Leibniz to Frege. Also in preparation are Logic From Russell to Gödel, The Emergence of Classical Logic, Logic and the Modalities in the Twentieth Century, and The Many-Valued and Non-Monotonic Turn in Logic. Further volumes will follow, including Mediaeval (...) and Renaissance Logic and Logic: A History of its Central. In designing the Handbook of the History of Logic, the Editors have taken the view that the history of logic holds more than an antiquarian interest, and that a knowledge of logic's rich and sophisticated development is, in various respects, relevant to the research programmes of the present day. Ancient logic is no exception. The present volume attests to the distant origins of some of modern logic's most important features, such as can be found in the claim by the authors of the chapter on Aristotle's early logic that, from its infancy, the theory of the syllogism is an example of an intuitionistic, non-monotonic, relevantly paraconsistent logic. Similarly, in addition to its comparative earliness, what is striking about the best of the Megarian and Stoic traditions is their sophistication and originality. Logic is an indispensably important pivot of the Western intellectual tradition. But, as the chapters on Indian and Arabic logic make clear, logic's parentage extends more widely than any direct line from the Greek city states. It is hardly surprising, therefore, that for centuries logic has been an unfetteredly international enterprise, whose research programmes reach to every corner of the learned world. Like its companion volumes, Greek, Indian and Arabic Logic is the result of a design that gives to its distinguished authors as much space as would be needed to produce highly authoritative chapters, rich in detail and interpretative reach. The aim of the Editors is to have placed before the relevant intellectual communities a research tool of indispensable value. Together with the other volumes, Greek, Indian and Arabic Logic, will be essential reading for everyone with a curiosity about logic's long development, especially researchers, graduate and senior undergraduate students in logic in all its forms, argumentation theory, AI and computer science, cognitive psychology and neuroscience, linguistics, forensics, philosophy and the history of philosophy, and the history of ideas.

The word "modem" in the title of this book refers primarily to post-medieval discussions, but it also hints at those medieval mo dal theories which were considered modem in contradistinction to ancient conceptions and which in different ways influenced philosophical discussions during the early modem period. The me dieval developments are investigated in the opening paper, 'The Foundations of Modality and Conceivability in Descartes and His Predecessors', by Lilli Alanen and Simo Knuuttila. Boethius's works from the early sixth century belonged (...) to the sources from which early medieval thinkers obtained their knowledge of ancient thought. They offered extensive discus sions of traditional modal conceptions the basic forms of which were: (1) the paradigm of possibility as a potency striving to realize itself; (2) the "statistical" interpretation of modal no tions where necessity means actuality in all relevant cases or omnitemporal actuality, possibility means actuality in some rel evant cases or sometimes, and impossibility means omnitemporal non-actuality; and (3) the "logical" definition of possibility as something which, being assumed, results in nothing contradic tory. Boethius accepted the Aristotelian view according to which total possibilities in the first sense must prove their met tle through actualization and possibilities in the third sense are assumed to be realized in our actual history. On these presump tions, all of the above-mentioned ancient paradigms imply the Principle of Plenitude according to which no genuine possibility remains unrealized. (shrink)

Logical form has always been a prime concern for philosophers belonging to the analytic tradition. For at least one century, the study of logical form has been widely adopted as a method of investigation, relying on its capacity to reveal the structure of thoughts or the constitution of facts. This book focuses on the very idea of logical form, which is directly relevant to any principled reflection on that method. Its central thesis is that there is no (...) such thing as a correct answer to the question of what is logical form: two significantly different notions of logical form are needed to fulfil two major theoretical roles that pertain respectively to logic and to semantics. This thesis has a negative and a positive side. The negative side is that a deeply rooted presumption about logical form turns out to be overly optimistic: there is no unique notion of logical form that can play both roles. The positive side is that the distinction between two notions of logical form, once properly spelled out, sheds light on some fundamental issues concerning the relation between logic and language.

In this paper, I would like to point out some problems of the presently reigning functional concept of the logical form of sentences, which presents itself as the final answer to the question of true logical form of sentences and, with this, as the basic scheme of logic. I believe that the present conception of the logical form of sentences is a historical result, which in many ways surpasses all former concepts of logical form in the (...) history of logic, but which seems not the final concept of the logical form. It contains some immanent limitations which are, in my opinion, linked mainly to the ‘functional’ concept of elementary sentences, which is the foundation of all other logical structures of sentences.

The passionate and staunch defence of logic of the controversial thinker Ibn Ḥazm, Abū Muḥammad ʿAlī b. Aḥmad b. Saʿīd of Córdoba (384-456/994-1064), had lasting consequences in the Islamic world. Indeed, his book Facilitating the Understanding of the Rules of Logic and Introduction Thereto, with Common Expressions and Juristic Examples (Kitāb al-Taqrīb li-ḥadd al-manṭiq wa-l-mudkhal ilayhi bi-l-alfāẓ al-ʿāmmiyya wa-l-amthila al-fiqhiyya), composed in 1025-1029, was well known and discussed during and after his time; and it paved the way for the studies (...) of his compatriots Ibn Bājjah (d. 1138), Ibn Ṭufayl (1185), and Ibn Rushd (1198), who each gave demonstrative reasoning a privileged place within the methods of attaining knowledge. Unfortunately, as too often in the history of science, Ibn Ḥazm’s innovative perspectives and contributions in logic have been overlooked or considered with an attitude of contempt. On the one hand, his work has been seen, at best, as promulgating the benefits of studying Aristotle’s logic, so that his contribution is assessed as more didactical than conceptual. And on the other hand, those who do examine his innovations often consider them to be mistaken. As indicated by Chejne (1984, p. 2) contempt towards the logical work of Ibn Ḥazm was also present in its reception by the Eastern philosophers who accused him of deviating from Aristotelian logic and of dabbling in things beyond his capability. However, a reassessment of his work on logic has since begun, by delving into the ways the thinker of Córdoba studied the links between deontic and modal qualification of propositions. In this context Lameer’s (2013) paper on the logical sources of Ibn Ḥazm is worth mentioning; the author (p. 417, footnote 1) observes that, although, strictly speaking, it was al-Fārābī who first drew the parallelism between deontic and modal concepts, it was Ibn Ḥazm who developed it and worked it out in a more precise manner. A primary aim of this paper is to help fill some of these gaps by stressing the role of the work of Ibn Ḥazm in developing a notion of deontic necessity deeply rooted in legal normativity, and in explicitly discussing the transference between deontic and modal concepts. According to our view; the basic units of Islamic deontic logic are what we might call, indulging in terminological anachronism, heteronomous imperatives. As it turns out, the heteronomy of imperatives within Islamic legal systems contrasts with those of the purely moral realm, which seem to be closer to an autonomous conception of moral law. There it concurs again with Leibniz’s proposal to define obligatory as “what is necessary for a good person to do”. In the present paper, we will focus on the heteronomous imperatives of legal systems rather than on the imperatives of the purely moral realm. In this context, the work of Ibn Ḥazm extends the parallelism between the necessity of events and that of human actions stressed by his predecessors. According to our understanding, Ibn Ḥazm’s parallelism can be rendered explicit formally by means of a conditional (or hypothetical) structure shared by both deontic and modal propositions. Moreover, this structure makes apparent that this parallelism displays an underlying system of “degrees”. Indeed, while in the domain of events, given some conditions, it makes sense to distinguish between an event that is more likely to happen than another. Ibn Ḥazm speaks of near and distant possibility (such as the higher degree of likelihood of rain, given the condensation of clouds in December, and its lower degree, when the condensation occurs in summer); and, in the domain of actions, the Islamic notion of weighting actions determines degrees of virtue (or of legal and moral value). So whereas the degree of virtue of performing a forbidden act as determined by the distribution of sanction and reward is 0, we obtain the same value by pondering the likelihood of an impossible event to take place. Furthermore, as discussed in section II.3.2, the system of values at work in the parallelism can be seen as opening the way to a more direct correspondence. Thus, while in the realm of nature, likelihood of occurrence of an event is dependent upon the conditions specific to the occurrence of that event; while, in the realm of jurisprudence, likelihood of performing an action is dependent upon the distribution of reward and sanction specific to that action (being that, given the choice to perform or not perform a given action, those that will be rewarded are more likely to be performed than those that are not). According to this perspective, the point of the parallelism is that both deontic and modal qualifications measure the degree of an action or event to become actual; that is – indulging once more in anachronism (but this time from the Leibnizian background) – the degree measures how feasible (facile) an action or event may be. This suggests that Ibn Ḥazm’s perspectives already herald the links to probability and possibility explored by Leibniz six centuries later – see for example Leibniz’s (1671, A VI, I, p. 424-26) use of probability in the context of conditional right. Nevertheless, it also shows a crucial difference to the approach developed in the Elementa Jura Naturalis: whereas Leibniz’s studies seek to define what is to be just or virtuous, the logical system of deontic imperatives within Islamic jurisprudence presupposes that what is to be virtuous has already been settled. Determining what is to be virtuous is not achieved by logical reasoning within the system of legal jurisprudence, but by delving into the higher objectives of the Sharīʿa. While developing our point, we will delve into the logical structure of the heteronomous imperatives. This distinguishes our contribution from the existing literature, such as the papers of Chejne (1984), Lameer (2014), and Guerrero (1997, 2010, 2014), which do not provide a logical analysis of the deontic concepts put into work by Ibn Ḥazm. The true antecedent to the present paper is the work of Farid Zidani (2007, 2015), who, so far as we know, was the first to undertake such a task. Some of our own developments and general epistemological thoughts go beyond Ibn Ḥazm’s framework and motivations; mainly those contained in sections II.3.2 and IV. However, according to our view, these reflections suggest that Ibn Ḥazm’s approach has the substance for a broader and deeper exploration of the logic of norms. The paper is structured as follows:I.Ibn Ḥazm’s Logic of Heteronomous Imperatives. After presenting some extracts of the relevant text, we proceed by providing a formal reconstruction of the five forms of deontic modalities. II. A Landmark in the History of the Logical Analysis of Norms. Duties and Modalities. In this section, we study the transferences from deontic to modal necessity and possibility. We briefly compare the deontic system of Islamic Jurisprudence with that of Leibniz.III. Leibniz and Hypothetical Imperatives in Law.IV. Beyond Ibn Ḥazm: Conclusions and the Work Ahead. We will conclude the paper by discussing briefly some conceptual points that distinguish the logic of heteronomous imperatives from contemporary deontic logic. Our final words will discuss deontic-modal parallelism in the context of Ibn Ḥazm’s rejection of reasoning by conjecture and what we call “the internalization of nature.”. (shrink)

Is logic masculine? Is women's lack of interest in the "hard core" philosophical disciplines of formal logic and semantics symptomatic of an inadequacy linked to sex? Is the failure of women to excel in pure mathematics and mathematical science a function of their inability to think rationally? Andrea Nye undermines the assumptions that inform these questions, assumptions such as: logic is unitary, logic is independenet of concrete human relations, and logic transcends historical circumstances as well as gender. In a series (...) of studies of the logics of historical figures--Parmenides, Plato, Aristotle, Zeno, Abelard, Ockham, and Frege--she traces the changing interrelationships between logical innovation and oppressive speech strategies, showing that logic is not transcendent truth but abstract forms of language spoken by men, whether Greek ruling citizens, or scientists.

The article discusses the formation of the philosophical concept of Leonid Evgenievich Gabrilovich (1878–1953), a Russian thinker of the first half of the 20th century. In the Rus­sian period of creativity, i.e. until 1918, as it is shown in the article, in his philosophi­cal development Gabrilovich experienced the influence of such fundamental theories as the philosophy of normative, immanent philosophy of W. Schuppe and phenomenology of E. Husserl. The article studies the following articles by L.E. Gabrilovich of the first, “Russian” (...) period: “On the concepts of truth and reliability in the theory of knowledge” 1908, “On two scientific concepts of thinking (to justify one dativist logic)” 1909, “On the meaning and essence of elementary concepts (an attempt at a new development of the problem of universal concepts)” 1910, as well as some others. It is shown that in his philosophical work L.E. Gabrilovich consistently and purposefully followed the de­velopment of his own concept, the nature of which makes it possible to attribute his phi­losophy to the logical and epistemological direction in Russian philosophy of the 20th cen­tury. The article proves that according to their ideas and structure, the analyzed texts of Gabrilovich revealed the themes of mathematical formalism, dativist logic, at the same time they were the main stages in the development of his own logical and epistemological concept as mathematical thinking and the actual form. L.E. Gabrilovich outlined the re­sults of these developments in the book “On Mathematical Thinking and the Concept of the Actual Form”, a 1914 essay written by him in German. It is concluded that the con­cept of “dativist logic”, developed by Gabrilovich in articles of 1909 and 1910, will later result in his theory of “actual forms”. (shrink)

Analyses of the dynamics of change present in Europe are not complete without taking into account the role and function of the critical approach as a founding element of European culture. An appreciation of critical thinking must go hand-in-hand with reflection on its essence, forms, and centuries-long tradition. The European philosophical tradition has thematized the problem of criticism since its appearance. This book contains articles on the history of philosophical criticism and ways that it has been understood in European (...) thought. Individual chapters contain both historical-philosophical and problem-oriented analyses, indicating the relationships between philosophical criticism and rationalism, logic, scepticism, atheism, dialectic procedure, and philosophical counseling, among others. Philosophical reflection on critical thinking allows for an acknowledgment of its significance in the fields of epistemology, philosophy of politics, aesthetics, methodology, philosophy of language, and cultural theory. The book should interest not only humanities scholars, but also scholars in other fields, as the development of an anti-dogmatic critical approach is a lasting and indispensible challenge for all disciplines.

This book recounts the remarkable history of efforts by significant medieval thinkers to accommodate the ontology of the Trinity within the framework of Aristotelian logic and ontology. These efforts were remarkable because they pushed creatively beyond the boundaries of existing thought while trying to strike a balance between the Church's traditional teachings and theoretical rigor in a context of institutional politics. In some cases, good theology, good philosophy, and good politics turned out to be three different things. The principal (...) thinkers discussed are Augustine, Boethius, Abélard, Gilbert of Poitiers, Bonaventure, Aquinas, Scotus, and Ockham. The aspects of Trinitarian doctrine dealt with are primarily internal ontological questions about the Trinity. The approach draws on history of theology and philosophy, as well as on the modern formal disciplines of set-theoretic semantics and formal ontology. Augustine inaugurated the project of constructing models of the Trinity in language drawn from Platonic and Aristotelian philosophy, especially the conceptual framework of Aristotle's Categories. He used the Aristotelian notions of substance and relation to set up a model whose aim was not so much to demystify the Trinity as to demonstrate the logical consistency of maintaining that there is one and only one God at the same time as maintaining that there are three distinct persons, each of whom is God. Standing against this tradition are various heretical accounts of the Trinity. The book also analyzes these traditions, using the same techniques. All these accounts of the Trinity are evaluated relative to the three constraints under which they were formed, bearing in mind that the constraints on philosophical theorizing are not limited to internal consistency but also take note of explanatory power. Besides analyzing and evaluating individual accounts of the Trinity, the book provides a novel framework within which different theories can be compared. (shrink)

The article analyses different forms of the theoretical paradigm of German Begriffsgeschichte. It focuses on the coherently formalized proposal made by Reinhard Koselleck, showing its relevance for the main Italian schools of interpretation. Koselleck is able to move beyond the historicist framework of Begriffsgeschichte on the basis of a theory of the Sattelzeit or Schwellenzeit--located between the eve of the seventeenth and the beginning of the eighteenth century--capable of orienting the reconstruction of the history of political concepts. This presupposition, (...) which refers to a theory of the 'Vorgriff' or historical conceptual reconstructions, draws upon and elaborates a key theme of the logic of the social sciences that was put forth by Max Weber. The possibility to adhere or not to this residual Weberian moment explains the two different modalities in which conceptual history has been interpreted in Italy: one pointing at the reconstruction of the conceptual framework of the nineteenth century, the other aiming at the philosophical-political reconstruction of the genesis, the historic limits and the crisis of the political concepts of Western modernity.

Metaphysicians have not always been sufficiently attentive to the problem of dependence. Those who have paid attention to it have disagreed over what depends on what: do minds depend on brains, or vice versa? accidents on substances? creatures on God? Even less attention, however, has been paid to the question of what dependence actually is; usually, some answer to this question is taken for granted, and consideration is given only to the subsequent questions of which things depend on which. The (...) present paper discusses what dependence is, not for its own sake, but, rather, as a case study concerning the question of form in metaphysical inquiry. Distinguishing logical from metaphysical form, one can say that certain difficulties in twentieth-century theories of dependence can be traced to the error of trying to answer a metaphysical question by making use of logical form instead of metaphysical form. The paper will proceed in three steps. First, it will discuss the leading twentieth-century theory of dependence, point out the difficulties with that theory, and make explicit the presuppositions about form that give rise to those difficulties. Second, the paper will show how those difficulties can be avoided by using a properly metaphysical form to understand dependence. Finally, the paper will reflect on the implications for metaphysical inquiry that can be drawn from the difference between the two approaches. (shrink)

This chapter reviews some of the history of discussions of logical form and offers a truth-theoretic account that traces back to Donald Davidson.

This is the first of a three-volume anthology intended as a companion to The Cambridge History of Later Medieval Philosophy. Volume 1 is concerned with the logic and the philosophy of language, and comprises fifteen important texts on questions of meaning and inference that formed the basis of Medieval philosophy.

The editors have provided a full introduction to the volume and detailed introductory (...) headnotes to each text; the volume is also indexed comprehensively. (shrink)

This paper outlines a truth-conditional view of logical form, that is, a view according to which logical form is essentially a matter of truth-conditions. The main motivation for the view is a fact that seems crucial to logic. As _§_1 suggests, fundamental logical relations such as entailment or contradiction can formally be explained only if truth-conditions are formally represented.§2 spells out the view. _§_3 dwells on its anity with a conception of logical form that has been (...) defended in the past. _§§_4-6 draw attention to its impact on three major issues that concern, respectively, the extension of the domain of formal explanation, the semantics of tensed discourse, and the analysis of quantication.

This paper claims that there is no such thing as the correct answer to the question of what is logical form: two significantly different notions of logical form are needed to fulfil two major theoretical roles that pertain respectively to logic and semantics. The first part of the paper outlines the thesis that a unique notion of logical form fulfils both roles, and argues that the alleged best candidate for making it true is unsuited for one of (...) the two roles. The second part spells out a considerably different notion which is free from that problem, although it does not fit the other role. As it will be suggested, each of the two notions suits at most one role, so the uniqueness thesis is ungrounded. (shrink)

This paper reviews the history of AI & Law research from the perspective of argument schemes. It starts with the observation that logic, although very well applicable to legal reasoning when there is uncertainty, vagueness and disagreement, is too abstract to give a fully satisfactory classification of legal argument types. It therefore needs to be supplemented with an argument-scheme approach, which classifies arguments not according to their logical form but according to their content, in particular, according to the (...) roles that the various elements of an argument can play. This approach is then applied to legal reasoning, to identify some of the main legal argument schemes. It is also argued that much AI & Law research in fact employs the argument-scheme approach, although it usually is not presented as such. Finally, it is argued that the argument-scheme approach and the way it has been employed in AI & Law respects some of the main lessons to be learnt from Toulmin’s The Uses of Argument. (shrink)

In the paper I suggest that a loose notion of logical form can be a useful tool for the understanding or evaluation of everyday language and the explicit and implicit content of communication. Reconciling ordinary language and logic provides formal guidelines for rational communication, giving strength and order to ordinary communication and content to logical schemas. The starting point of the paper is the idea that the bearers of logical form are not natural language sentences, but what (...) we communicate with them, that is, their content in a particular context. On the basis of that idea, I propose that we can ascribe logical proprieties to what is communicated using ordinary language and suggest a continuum between semantic phenomena such as explicatures and pragmatic communicational strategies such as (particularized) conversational implicatures, which challenges the idea that an implicatum is completely separate from what is said. I believe that this continuum can be best explained by the notion of logical form, taken as a propriety of sentences relative to particular interpretations. (shrink)

Written by a team of distinguished scholars, this is an authoritative and comprehensive history of Western philosophy from its earliest beginnings to the present day. Illustrated with over 150 color and black-and-white pictures, chosen to illuminate and complement the text, this lively and readable work is an ideal introduction to philosophy for anyone interested in the history of ideas. From Plato's Republic and St. Augustine's Confessions through Marx's Capital and Sartre's Being and Nothingness, the extraordinary philosophical dialogue between (...) great Western minds has flourished unabated through the ages. Dazzling in its genius and breadth, the long line of European and American intellectual discourse tells a remarkable story--a quest for truth and wisdom that continues to shape our most basic ideas about human nature and the world around us. That quest is brilliantly brought to life in The Oxford History of Western Philosophy. With spectacular illustrations--including sixteen pages of full-color plates--this splendidly written volume takes the reader on a magnificient chronological tour through the revolutions of thought that have forged the Western philosophical tradition from ancient times to the present. Throughout, the six contributors--an internationally renowned team of philosophers including Roger Scruton, Anthony Quinton, and Anthony Kenny--bring the astonishingly diverse, wide-ranging landscape of intellectual history into sharp focus, emphasizing how notions seen today as part of an inevitable march of ideas were in their own time often considered radical, if not revolutionary. Thus we are treated, for example, to lively accounts of how Plato's "theory of forms" and Aristotle's pioneering exercises in logic broke with the past to irrevocably alter the course of Western thought. The authors also reveal the relationships between landmark thinkers, and the ways they drew on their intellectual heritage. They show, for instance, how St. Augustine and Aquinas, though advancing the cause of Christian doctrine, picked up where their pagan Greek forebears had left off. We witness how, during the Renaissance, the profound empiricist ideas underlying Descarte's famous utterance--"I think, therefore I exist"--lived in a tense but complementary relationship with Locke's rationalist theories. Moving into the eighteenth and nineteenth centuries, the book explores how Hume greatly influenced Kant's conception of the "transcendental aesthetic," and how Hegel drew upon the lesser known (but groundbreaking) work of Fichte and Schelling. The authors bring the story up to our own time, vividly recounting the existential trend from Nietzsche ("God is dead") to Sartre, along with other increasingly fractious schools of thought. Along the way, we not only encounter the vast intellectual riches of the Western mind, but we also meet the personalities behind the great thoughts, from the saintly Hume (described by Adam Smith as having "come as near to perfection as anybody could") to the ill-mannered outcast Fichte. And the hundreds of maps and striking illustrations (including full-color reproductions of art ranging from medieval manuscripts to the works of Raphael, Ingres, and Magritte) form an integral part of the book, revealing the interweaving of art and ideas through the ages, as artists have striven to give visual immediacy to philosophical concepts. The Oxford History of Western Philosophy is the most authoritative single-volume account ever written for the general reader. Engagingly written and astonishingly far-reaching, it provides the consummate introduction to the intellectual bedrock upon which Western civilization is built. (shrink)

This essay aims to shed new light on the theoretical pertinence of classical Indian logic and epistemology in Benedetto Croce's criticism of Western Aristotelian and modern logic. As a matter of fact, Croce gave a positive and extraordinarily enterprising evaluation of “Indian Logic” in his review of Hermann Jacobi's Indische Logik (1905) and in his book Logic as the Science of the Pure Concept (1996 [1909]). Yet Croce's significant and considerable evaluation of “Indian Logic” has remained neglected until today. This (...) essay tries to clear the field of some prejudices that misled scholarly research on Croce and Indian philosophy, and it glosses in detail the “neglected” judgment on “Indian Logic” in Croce's Logic. In doing so, it critically discusses some epistemological questions starting from Croce's philosophy, such as the character of “natural induction,” the relationship between language and thought, and the connection between historical languages and logical forms.

Logical form and logical analysis as the search for it have been introduced during the development of logic and analytical philosophy and are still widely considered as key tools or methods for the solution of philosophical puzzles. It is instructive to have a look at a criticism of these presupositions and I present Wittgenstein as the author who provides such a criticism. I present a development of his view of logical form which went from the thesis of (...) the ineffability of logical form to the denial of the meaningfulness of the notion of logical form as such. This refusal is linked to Wittgenstein’s abandonment of the idea of the language of pure experience. The method of philosophical therapies is presented as an alternative to logical analysis and this methodology is linked with Wittgenstein’s consideration of game and family resemblance. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge History of Seventeenth-Century Philosophy by Daniel Garber, Michael AyersDonald RutherfordDaniel Garber, Michael Ayers, editors. The Cambridge History of Seventeenth-Century Philosophy. 2 vols. Cambridge: Cambridge University Press, 1998. Pp. xii + 1616. Cloth, $175.Over a decade in preparation, this latest addition to the Cambridge History of Philosophy is an enormous achievement—both in its size and the contribution it makes to redefining [End Page 165] (...) the landscape of seventeenth-century philosophy. The editors make no bones about their intention to rewrite the history of early modern philosophy, reversing the trend dominant through much of this century of reading seventeenth-century philosophers in the light of twentienth-century “interests and preconceptions” (4). As they note, the movement to historicize our understanding of seventeenth-century philosophy has been underway for some time in the English-speaking world, furthered in many cases by contributors to these volumes. From this perspective, the present work represents, if not the culmination, at least a progress report on these efforts and the success they have achieved.As in previous volumes of the Cambridge History, the subject matter is treated thematically. Consistent with their larger goal, the editors have further attempted to organize the volumes in a way that remains faithful to the expectations of the period. Part I sets the stage with chapters that establish the larger social and historical context: “The institutional setting” (Richard Tuck); “The intellectual setting” (Stephen Menn); and “European responses to non-European culture: China” (D.E. Mungello). For the rest, the editors write, “the structure of the collection corresponds to one way, at any rate, in which an educated European of the seventeenth century might have organized the domain of philosophy” (2). First comes logic (including method and general ontology); then, the primary categories of being (God, body, soul); finally, the basic operations of the soul (understanding, will, action), whose treatment comprehends the topics of epistemology and ethics.Part II, “Logic, Language, and Abstract Objects,” opens with three short chapters by Gabriel Nuchelmans that survey the terrain of seventeenth-century logic according to the traditional divisions of term, proposition/judgment, and argument. These are followed by contributions on “Method and the study of nature” (Peter Dear); “Universal, essences, and abstract entities” (Martha Bolton); and “Individuation” (Udo Thiel).The discussion of metaphysics proper begins in Part III with the most fundamental being: God. Included here are chapters that examine specific theological issues—“The idea of God” (Jean-Luc Marion); “Proofs of the existence of God” (Jean-Robert Armogathe); “The Cartesian dialectic of creation” (Thomas M. Lennon)—as well as ones that deal more broadly with the crucial connection between philosophy and religion: “The relation between theology and philosophy” (Nicholas Jolley) and “The religious background of seventeenth-century philosophy” (Richard Popkin).Part IV, “Body and the Physical World,” forms the single largest part of the book and its intellectual core. It opens with two chapters—“The scholastic background” (Roger Ariew and Alan Gabbey) and “The occultist tradition and its critics” (Brian Copenhaver)—that effectively mark out the boundaries of the “new philosophy” that emerges in conjunction with the development of seventeenth-century science. These are followed by a series of chapters that examine particular features of that philosophy: “Doctrines of explanation in late scholasticism and in the mechanical philosophy” (Steven Nadler); “New doctrines of body and its powers, place, and space” (Daniel Garber, John Henry, Lynn Joy, and Alan Gabbey); “Knowledge of the existence of body” (Charles McCracken); “New doctrines of motion” (Alan Gabbey); “Laws of nature” (J.R. Milton); and “The mathematical realm of nature” (Michael Mahoney). [End Page 166]The final section of Volume I takes up the third main category of being: “Spirit.” It begins with Daniel Garber’s overview of the positions of the major figures, “Soul and mind: Life and thought in the seventeenth century,” followed by chapters on “Knowledge of the soul” (Charles McCracken); “Mind-body problems” (Daniel Garber and Margaret Wilson); “Personal identity” (Udo Thiel); and “The passions in metaphysics and the theory of action” (Susan James).Volume II of the History is devoted to topics that, in one way or another, elaborate operations of the soul.

This paper pursues the suggestion of St. Anselm that action expressions can be parsed by saying that the agent makes a certain proposition true. Using the model syntax of Pörn and the relatedness logic of Epstein, it is shown how St. Anselm's approach can reveal the logical form of some common action locutions.

Puzzle-solving, like several other everyday activities, appears in a more sophisticated and ramified form in the realm of natural science. Improving on Thomas Kuhn's rudimentary account of puzzles in science, this paper formulates logical and functional criteria for the occurrence of scientific puzzles, and examines the two-fold nature of their solutions. Then, with the aid of erotetic logic, puzzle-posing questions are identified, their presuppositional relations to scientific theory and explanations are explored, and a new tool for history of (...) science research is developed.

Modern social theory, by and large, has aimed at reducing the complexity of action situations to a set of manageable abstractions. But these abstractions, whether functionalist or linguistic, fail to grasp the indeterminacy of action situations.Action proceeds by discovery and combination. The logic of action is serendipitous and combinative. From these characteristics, a number of consequences flow: The whole field of our intentions is engaged in each action situation, and cannot really be understood apart from the situation itself. In action (...) situations we remain aware of the problems of categorization, including the dangers of infinite regress and the difficulties of specifying borders and ranges of categories. In action situations, attention is in permanent danger of being overwhelmed. We must deal with many features of action situations outside of attention; in doing so, we must entertain simultaneously numerous possibilities of action. Emotional expression is a way of talking about the kinds of possibilities we entertain. Expression and action have a rebound effect on attention. "Effort" is required to find appropriate expressions and actions, and rebound effects play a role in such effort, making it either easier or more difficult.Recent theoretical trends have failed to capture these irreducible characteristics of action situations, and have slipped into a number of errors. Language is not rich in meanings or multivocal, except as put to use in action situations. The role of "convention" in action situations is problematic, and therefore one ought not to talk of "culture." Contrary to the assertions of certain theorists, actors do not follow strategies, except when they decide to do so. Actors do not "communicate," in the sense of exchanging information, except in specially arranged situations. More frequently, they intervene in the effortful management of attention of their interlocutors. Dialogue, that is, very commonly becomes a form of cooperative emotional effort.From these considerations, it follows that the proper method for gaining social knowledge is to examine the history of action and of emotional effort, and to report findings in the form of narrative.

The aim of this commentary is to show that a new development in formal logic, namely paraconsistent logic, should be connected with the laws of form. This note also includes some personal history to serve as background.

Consider the following argument: All men are mortal; Socrates is a man; therefore, Socrates is mortal. Intuitively, what makes this a valid argument has nothing to do with Socrates, men, or mortality. Rather, each sentence in the argument exhibits a certain logical form, which, together with the forms of the other two, constitute a pattern that, of itself, guarantees the truth of the conclusion given the truth of the premises. More generally, then, the logical form of a sentence (...) of natural language is what determines both its logical properties and its logical relations to other sentences. The logical form of a sentence of natural language is typically represented in a theory of logical form by a well-formed formula in a ‘logically pure’ language whose only meaningful symbols are expressions with fixed, distinctly logical meanings (e.g., quantifiers). Thus, the logical forms of the sentences in the above argument would be represented in a theory based on pure predicate logic by the formulas ‘∀x(Fx ⊃ Gx)’, ‘Fy’, and ‘Gy’, respectively, where ‘F’, ‘G’, and ‘y’ are all free variables. The argument’s intuitive validity is then explained in virtue of the fact that the logical forms of the premises formally entail the logical form of the conclusion. The primary goal of a theory of logical form is to explain as broad a range of such intuitive logical phenomena as possible in terms of the logical forms that it assigns to sentences of natural language.

This paper explores the history of ELIZA, a computer programme approximating a Rogerian therapist, developed by Jospeh Weizenbaum at MIT in the 1970s, as an early AI experiment. ELIZA’s reception provoked Weizenbaum to re-appraise the relationship between ‘computer power and human reason’ and to attack the ‘powerful delusional thinking’ about computers and their intelligence that he understood to be widespread in the general public and also amongst experts. The root issue for Weizenbaum was whether human thought could be ‘entirely (...) computable’. This also provoked him to re-consider the nature of machine intelligence and to question the instantiation of its logics in the social world, which would come to operate, he said, as a ‘slow acting poison’. Exploring Weizenbaum’s 20th Century apostasy, in the light of ELIZA, illustrates ways in which contemporary anxieties and debates over machine smartness connect to earlier formations. In particular, this article argues that it is in its designation as a computational therapist that ELIZA is most significant today. ELIZA points towards a form of human–machine relationship now pervasive, a precursor of the ‘machinic therapeutic’ condition we find ourselves in, and thus speaks very directly to questions concerning modulation, autonomy, and the new behaviorism that are currently arising.

In this collection of essays written over a period of twenty years, Solomon Feferman explains advanced results in modern logic and employs them to cast light on significant problems in the foundations of mathematics. Most troubling among these is the revolutionary way in which Georg Cantor elaborated the nature of the infinite, and in doing so helped transform the face of twentieth-century mathematics. Feferman details the development of Cantorian concepts and the foundational difficulties they engendered. He argues that the freedom (...) provided by Cantorian set theory was purchased at a heavy philosophical price, namely adherence to a form of mathematical platonism that is difficult to support. -/- Beginning with a previously unpublished lecture for a general audience, Deciding the Undecidable, Feferman examines the famous list of twenty-three mathematical problems posed by David Hilbert, concentrating on three problems that have most to do with logic. Other chapters are devoted to the work and thought of Kurt Gödel, whose stunning results in the 1930s on the incompleteness of formal systems and the consistency of Cantors continuum hypothesis have been of utmost importance to all subsequent work in logic. Though Gödel has been identified as the leading defender of set-theoretical platonism, surprisingly even he at one point regarded it as unacceptable. -/- In his concluding chapters, Feferman uses tools from the special part of logic called proof theory to explain how the vast part--if not all--of scientifically applicable mathematics can be justified on the basis of purely arithmetical principles. At least to that extent, the question raised in two of the essays of the volume, Is Cantor Necessary?, is answered with a resounding no. -/- This volume of important and influential work by one of the leading figures in logic and the foundations of mathematics is essential reading for anyone interested in these subjects.

What is the relation of logic to thinking? My dissertation offers a new argument for the claim that logic is constitutive of thinking in the following sense: representational activity counts as thinking only if it manifests sensitivity to logical rules. In short, thinking has to be minimally logical. An account of thinking has to allow for our freedom to question or revise our commitments – even seemingly obvious conceptual connections – without loss of understanding. This freedom, I argue, (...) requires that thinkers have general abilities to respond to support and tension among their thoughts. And these abilities are constituted by following logical rules. So thinkers have to follow logical rules. But there isn’t just one correct logic for thinking. I show that my view is consistent with logical pluralism: there are a range of correct logics, any one of which a thinker might follow. A logic for thinking does, however, have to contain certain minimal principles: Modus Ponens and Non-Contradiction, and perhaps others. We follow logical rules by exercising logical capacities, which display a distinctive first-person/third-person asymmetry: a subject can find the instances of a rule compelling without seeing them as instances of a rule. As a result, there are two limits on illogical thinking. First, thinkers have to tend to find instances of logical rules compelling. Second, thinkers can’t think in obviously illogical ways. So thinking has to be logical – but not perfectly so. When we try to think, but fail, we produce nonsense. But our failures to think are often subjectively indistinguishable from thinking. To explain how this occurs, I offer an account of nonsense. To be under the illusion that some nonsense makes sense is to enter a pretence that the nonsense is meaningful. Our use of nonsense within the pretence relies on the role of logical form in understanding. Finally, while the normativity of logic doesn’t fall directly out of logical constitutivism, it’s possible to build an attractive account of logical normativity which has logical constitutivism as an integral part. I argue that thinking is necessary for human flourishing, and that this is the source of logical normativity. (shrink)

Vernacularism is the view that logical forms are fundamentally assigned to natural language expressions, and are only derivatively assigned to anything else, e.g., propositions, mental representations, expressions of symbolic logic, etc. In this paper, we argue that Vernacularism is not as plausible as it first appears because of non-sentential speech. More specifically, there are argument-premises, meant by speakers of non-sentences, for which no natural language paraphrase is readily available in the language used by the speaker and the hearer. The (...) speaker can intend this proposition and the hearer can recover it (and its logical form). Since they cannot, by hypothesis, be doing this by using a sentence of their shared language, the proposition-meant has its logical form non-derivatively, which falsifies Vernacularism. We conclude the paper with a brief review of the debate on incomplete definite descriptions in which Vernacularism is assumed as a suppressed premise. (shrink)

The investigation into logical form and structure of natural sciences and mathematics covers a significant part of contemporary philosophy. In contrast to this, the metatheory of normative theories is a slowly developing research area in spite of its great predecessors, such as Aristotle, who discovered the sui generis character of practical logic, or Hume, who posed the “is-ought” problem. The intrinsic reason for this situation lies in the complex nature of practical logic. The metatheory of normative educational philosophy and (...) theory inherits all the difficulties inherent in the general metatheory but has also significantly contributed to its advancement. In particular, the discussion on its mixed normative-descriptive character and complex composition has remained an important part of research in educational philosophy and theory. The two points seem to be indisputable. First, the content of educational philosophy and theory is a complex one, connecting different disciplines. Second, these disciplines are integrated within the logical form of practical inference or means-end reasoning. On the other hand, the character of consequence relation in this field, although generally recognized as specific, represents an unresolved prob- lem, a solution of which requires a sophisticated logical theory and promises to influence the self- understanding of educational philosophy and theory.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.2 (2003) 282-284 [Access article in PDF] Bruce Kuklick. A History of Philosophy in America, 1720-2000. New York: Oxford University Press, 2001. Pp. xiii + 326. Cloth, $30.00. Scott L. Pratt. Native Pragmatism: Rethinking the Roots of American Philosophy. Bloomington: Indiana University Press, 2002. Pp. xviii + 316. Cloth, $49.95. Paper, $21.95. In his earlier works Bruce Kuklick has studied major (...) figures and episodes in the evolution of American thought, most famously the Golden Age of Harvard. In the present book he proposes to tell the whole story. Beginning, as it must, with Jonathan Edwards, Part I traces the long and difficult process by which philosophy gradually distinguishes itself from theology. Part II deals magisterially with the age of pragmatism, from Darwin to Dewey, and Part III with professional philosophy in the twentieth century. Kuklick's account of this latest development, briefly adumbrated in his previous books, is the freshest and (to this retired professional) most engaging part of the narrative. Once philosophy had loosened the bonds that tied it to theology, once sciences like psychology, originally parts of philosophy, had declared independence and set out on their own, and once philosophy's role as counselor to private morals and public policy had been taken over by psychoanalysis, economics, sociology, and political science, philosophers had to discover a new identity for themselves. Inspired by logical positivism and the linguistic ruminations of the late Wittgenstein, professional philosophy came to mean, very largely, a preoccupation with problems of logic, philosophy of language, philosophy of science, and epistemology. The result was that, apart from undergraduate lectures and occasional ventures into the popular media, what philosophers said and wrote, intelligible only to other philosophers, became irrelevant to just about everything of personal and public interest, and even to the traditional concerns of philosophy itself with the nature of reality and the conduct of life.The eventual arrival in the American academy of phenomenology, existentialism, and deconstruction, in spite of their apparent engagement with "real life" and their appeal to undergraduates, only bred another species of professionals and precipitated the familiar antagonism between analytic and continental philosophy. Late in the last century Richard Rorty, a preeminent analytic philosopher, broke ranks, discovered first Heidegger and Derrida, then William James and John Dewey, and declared himself a pragmatist. He characterized philosophy as a single voice in the conversation of the West, which also included literature, literary criticism, the arts, and all the sciences both natural and humane. But he remains a philosopher of language. The pragmatism of the nineteenth century was a low-mimetic [End Page 282] form of the high-mimetic idealism from which it emerged: from Royce to James. Rorty's pragmatism not only takes for granted the (often implicit) materialism and atheism of analytic philosophy, but is itself a new way of understanding and using language. It has been called, inverting James, an old name for a new way of thinking.But I need to correct this overly simple account. As Kuklick is aware, philosophy in America, though it did succeed in detaching itself from theology, has never wholly dissolved its ties to religion. Royce and James in the nineteenth century and Dewey in the twentieth continued to be preoccupied with religious questions, especially with the apparent conflict of religion and science suggested by Darwin's theory. Religious interests survive, barely, in "critical realism." And even though analytic philosophy would seem to be most comfortable with atheism, more than a few thinkers trained in analysis have combined analytic logic and religious faith. Witness the Society of Christian Philosophers. On the whole, however, professional philosophy has been devoid of religious, socio-political, or existential interest. This should not be surprising. All genuine professions serve an end beyond themselves—as medicine serves health, law justice, and theology salvation. But when philosophy becomes a "profession," it has no end but self-preservation, i.e., creating more philosophers and finding jobs for them.One slightly disconcerting feature of Kuklick's...

The Hegel Lectures SeriesSeries Editor: Peter C. HodgsonHegel's lectures have had as great a historical impact as the works he himself published. Important elements of his system are elaborated only in the lectures, especially those given in Berlin during the last decade of his life. The original editors conflated materials from different sources and dates, obscuring the development and logic of Hegel's thought. The Hegel Lectures series is based on a selection of extant and recently discovered transcripts and manuscripts. The (...) original lecture series are reconstructed so that the structure of Hegel's argument can be followed. Each volume presents an accurate new translation accompanied by an editorial introduction and annotations on the text, which make possible the identification of Hegel's many allusions and sources. Lectures on the History of PhilosophyVolume II: Greek PhilosophyHegel's Lectures on the History of Philosophy offer one of the best points of entry to his philosophical system. The second volume covers a thousand years of ancient Greek philosophy; this is the period to which Hegel devoted by far the most attention, and which he saw as absolutely fundamental for all that came after it. This edition sets forth clearly, and for the first time for the English reader, what Hegel actually said. It forms part of OUP's Hegel Lectures series, presenting accurate new translations accompanied by editorial introductions and annotations.These lectures challenged the antiquarianism of Hegel's contemporaries by boldly contending that the history of philosophy is itself philosophy, not just history. It portrays the journey of reason or spirit through time, as reason or spirit comes in stages to its full development and self-conscious existence, through the successive products of human intellect and activity. Hegel's Lectures on the History of Philosophy proved to be extremely influential on the intellectual history of the past two centuries. These lectures are crucial to understanding Hegel's own systematic philosophy in its constructive aspect, as well as his views on the centrality of reason in human history and culture. The volume on Greek Philosophy covers the first one thousand years, the period to which Hegel devoted by far the most attention, and which he saw as absolutely fundamental for all that came after it. This edition adapts the considerable editorial resources of the German edition that it translates, to the needs of the general reader as well as the serious scholar, so as to constitute an unparalleled resource on this topic in the English language.

The academic History of Philosophy in Lithuania in three volumes will be published by the Institute of Culture, Philosophy and Art. The first presented volume covers the development of Lithuanian philosophy from the 16th to the 18th centuries. It includes late medieval and Renaissance philosophy, the second scholasticism and modern philosophy. The first Lithuanians to be introduced to philosophy were young members of the gentry who studied in European universities at the end of the 14th century. The recently baptized (...) Lithuania strove to adopt Western culture and to present itself as a Western state. Some graduated from the universities as bachelors or masters of philosophy and returned to their country. At the end of the 14th century, Vilnius Cathedral School was founded. The elements of logic were probably taught there. The growth of the political and economic power of the Grand Duchy of Lithuania brought about the need for higher education. That need was significantly increased by the growing activity of various religious orders. In 1507 the Dominicans started teaching philosophy and theology to their novices. They were able to teach late medieval philosophy in its thomistic interpretation. We can regard 1507 as the year Lithuania benefited form a new phenomenon, professional philosophy, and the Dominicans as its initiators. They taught not only the disciplines of late medieval philosophy but also the basics of the other sciences. The Dominicans, and later the Jesuits, Franciscans, Bernardines, Carmelites, Trinitarians and other monastic orders, enriched intellectual life in Lithuania by teaching philosophy in their schools.

In his logical treatises, John Mair develops a method and a set of rules for the verification of modal propositions, which is in the spirit of his predecessors Ockham and Buridan, but ultimately goes beyond them. He calls this method positio de inesse. It is also by this method that the truth conditions for divided modal propositions are set out. There is a standard interpretation of it as a form of reductionist method, and scholars have been tempted to think (...) that it was motivated by an implicit rejection of de re modal properties shared by Mair and other sixteenth- century nominalists. After presenting the background to Mair’s writings on the semantics of modal propositions, in this paper we revisit Mair's version of the method of positio de inesse. We argue that it is based on some basic semantic rules and contend that this procedure analyzes divided modal propositions into singular de re sentences referring to possible objects. Consequently, we conclude that this method does not reflect a reductionist approach to modal discourse. We instead provide an alternative interpretation. (shrink)

This work aims to foster interest in the links between a particular theoretical and conceptual development of sociological science in Italy and the debate surrounding the history of scientific subjects, here called the epistemological history of various disciplines. The author sets out to trace the points of view emerging from Italian epistemological sociology between the early twentieth and twenty-first centuries and related to the debate on the historical and philosophical sciences. The intention resides in revealing the distinctive characteristics (...) of the latter, their internal (logical and methodological) rather than external (historical and social) factors, while investigating the task of the new historians of science confronted with the changes caused by various knowledge and forms of technological know-how. The text provides the contemporary scientific community with a new route to follow when seeking to rationally establish and write the history of sociology. The addressees are, more than anything else, the new generation of scholars of the history of science. (shrink)

Context: Maturana’s work is not easy to follow. Correct and full understanding of his work has still to be achieved in spite of its importance. Problem: The objective of this paper is to investigate the core logic penetrating Maturana’s wide-ranging work and to place his work in the history of western thought. Method: Through intensive reading of his wide-ranging work, I intended to grasp the core biological structure that he advocates, namely, his core logic. Results: Maturana’s biology is the (...) biology of structural determinism. It is embodied in a composite entity called a “structure-determined system” with two non-intersecting domains - the domain of interactions and the domain of the composition of components – which can be called the core structure or the core logic of his biology. From the perspective of the history of western thought, Aristotle and Schopenhauer can be regarded as good candidates as the precursors of Maturana’s work, and his work can be characterized as an advanced form of Aristotle’s hylomorphism, depicted on the horizon of Schopenhauer’s world of “Vorstellung” (bringing-forth). Implications: This finding will be useful for understanding Maturana’s wide-ranging work and its place in the history of western thought. (shrink)
