Book synopsis: For the Pre-Socratic philosophers the soul was the source of movement and sensation, while for Plato it was the seat of being, metaphysically distinct from the body that it was forced temporarily to inhabit. Plato's student Aristotle was determined to test the truth of both these beliefs against the emerging sciences of logic and biology. His examination of the huge variety of living organisms - the enormous range of their behaviour, their powers and their perceptual sophistication - convinced (...) him of the inadequacy both of a materialist reduction and of a Platonic sublimation of the soul. In De Anima, he sought to set out his theory of the soul as the ultimate reality of embodied form and produced both a masterpiece of philosophical insight and a psychology of perennially fascinating subtlety.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Avicenna's Theory of Science: Logic, Metaphysics, Epistemology by Riccardo StrobinoThérèse-Anne DruartRiccardo Strobino. Avicenna's Theory of Science: Logic, Metaphysics, Epistemology. Oakland: University of California Press, 2021. Pp. xvi + 428. Hardback, $95.00.Strobino's remarkable book does not simply present Avicenna's theory of science; it also highlights the importance of demonstration not only for logic but also for metaphysics and epistemology. Hence, Strobino's work is essential to appreciate (...) and better understand Avicenna's philosophy as a whole.Strobino grounds his research on Avicenna's theory of science in his Book of Demonstration in the Shifā', which focuses on Aristotle's Posterior Analytics. Taking into account the lack of any translation into English or any other main modern language as well as the lack of a full medieval Latin translation (only chapter 7 of book 3 exists in a medieval Latin version) of Avicenna's text, Strobino kindly provides in appendix C (357–71) a detailed "map" of this text, useful not only to readers who cannot handle Arabic but even to those who can, as the [End Page 326] text is so rich and complex. A simple but careful look at this map confirms what Strobino makes clear and insists upon: Avicenna greatly develops, enriches, completes, and even outgrows some of Aristotle's views. The Book of Demonstration is far more than a commentary on the Posterior Analytics; it is a complete reworking of it.Strobino shows that Avicenna grounds his theory of demonstration and science on two basic notions—conception (tasawwur) and assertion (tasdīq, which some other scholars translate as "assent")—and so gives a unified approach to his theory. Scientific conceptions require better understanding of definition and description. Avicenna builds definitions and descriptions on essentialism and, therefore, grounds them in metaphysics. As for scientific assertions, in contradistinction to nonscientific ones, they must be necessary and give the cause. Therefore, Avicenna places great importance on modality and develops modal syllogisms, whereas Aristotle focused on categorical syllogisms and neglected hypothetical and disjunctive syllogisms. Avicenna also elaborates a sophisticated account of modality and its metaphysical implications. Furthermore, he broadens and enriches the appreciation of causality and explanation. These developments, according to Strobino, lead Avicenna to set forth an intricate division and hierarchy of the sciences under metaphysics, which provides their ultimate principles and allows for a unified understanding of the sciences while respecting their particularities.According to Strobino, Avicenna is keen to develop a theory of science that gives a good account of science as it is practiced. Strobino carefully shows how Avicenna's theory better reflects this practice than does Aristotle's.Strobino does not simply highlight how much Avicenna distances himself from Aristotle and goes far beyond what the Posterior Analytics yields, but also shows how much Avicenna relies on points adumbrated by his predecessor al-Fārābī in his own Book of Demonstration.The way Strobino through his analysis of demonstration links Avicenna's understanding of logic, epistemology, and metaphysics underscores the coherence and unity of Avicenna's philosophy. Scholars were aware of the importance of demonstration for Avicenna in various philosophical fields, but until the release of this book, they seemed not to have fully grasped the centrality and essential role played by the Avicennian understanding and focus on demonstration.Of course, Strobino does not limit himself to an analysis of passages in the Book of Demonstration. He has an encompassing knowledge of Avicenna's texts and uses them well to flesh out and enrich what remains terse in the Book of Demonstration. He even takes into account the way one of his successors, al-Tūsī, reads him. He also shows an extensive and wide-ranging knowledge of Aristotle's texts and of Aristotelian scholarship, as well as an interest in the Greek commentators and Galen and their relevance for interpreting Avicenna.Avicenna's Theory of Science is not an easy book to read, as it is often very technical, particularly when dealing with purely logical points or issues, but reading it is rewarding if one does so slowly and meditatively. The author, in fact, illuminates difficult matters but does not waste words. From... (shrink)

Avicenna is the most influential figure in the intellectual history of the Islamic world. This book is the first comprehensive study of his theory of science, which profoundly shaped his philosophical method and indirectly influenced philosophers and theologians not only in the Islamic world but also throughout Christian Europe and the medieval Jewish tradition. A sophisticated interpreter of Aristotle’s _Posterior Analytics_, Avicenna took on the ambitious task of reorganizing Aristotelian philosophy of science into an applicable model of scientific reasoning, (...) striving to identify conditions of certainty for scientific assertions and conditions of adequacy for real definitions. Riccardo Strobino combines philosophical and textual analysis to explore the scope and nature of Avicenna’s contributions to the logic of scientific reasoning in his effort to recalibrate Aristotle’s model and overcome some of its internal limitations. Focusing on a broad array of philosophical innovations at the intersection of logic, metaphysics, and epistemology, this book casts light on an essential aspect of the thought of the preeminent philosopher and physician of the Islamic world.

Necessity and sufficiency are the building blocks of all successful explanations. Yet despite their importance, these notions have been conceptually underdeveloped and inconsistently applied in explainable artificial intelligence, a fast-growing research area that is so far lacking in firm theoretical foundations. In this article, an expanded version of a paper originally presented at the 37th Conference on Uncertainty in Artificial Intelligence, we attempt to fill this gap. Building on work in logic, probability, and causality, we establish the central role of (...) necessity and sufficiency in XAI, unifying seemingly disparate methods in a single formal framework. We propose a novel formulation of these concepts, and demonstrate its advantages over leading alternatives. We present a sound and complete algorithm for computing explanatory factors with respect to a given context and set of agentive preferences, allowing users to identify necessary and sufficient conditions for desired outcomes at minimal cost. Experiments on real and simulated data confirm our method’s competitive performance against state of the art XAI tools on a diverse array of tasks. (shrink)

Many books explain what is known about the universe. This book investigates what cannot be known. Rather than exploring the amazing facts that science, mathematics, and reason have revealed to us, this work studies what science, mathematics, and reason tell us cannot be revealed. In The Outer Limits of Reason, Noson Yanofsky considers what cannot be predicted, described, or known, and what will never be understood. He discusses the limitations of computers, physics, logic, and our own thought processes. Yanofsky describes (...) simple tasks that would take computers trillions of centuries to complete and other problems that computers can never solve; perfectly formed English sentences that make no sense; different levels of infinity; the bizarre world of the quantum; the relevance of relativity theory; the causes of chaos theory; math problems that cannot be solved by normal means; and statements that are true but cannot be proven. He explains the limitations of our intuitions about the world -- our ideas about space, time, and motion, and the complex relationship between the knower and the known. Moving from the concrete to the abstract, from problems of everyday language to straightforward philosophical questions to the formalities of physics and mathematics, Yanofsky demonstrates a myriad of unsolvable problems and paradoxes. Exploring the various limitations of our knowledge, he shows that many of these limitations have a similar pattern and that by investigating these patterns, we can better understand the structure and limitations of reason itself. Yanofsky even attempts to look beyond the borders of reason to see what, if anything, is out there. (shrink)

In the introductory first chapter the author states his conviction that Aristotle’s theory of learning, at the center of which stands the apodeictic syllogism, is inadequate because partial. Chapter 2 is a balanced survey of Aristotle’s syllogistic, which does not serve the purpose of discovery, but is intended to turn into science knowledge already acquired. All learning proceeds from preexisting knowledge which is structured by demonstration. Next Bauman turns to Plato’s theory of learning as present in the Meno: (...) learning is remembering. His account of the Socratic method of making a disciple see the truth by pertinent questions is excellent. He warns us to avoid extreme interpretations of ἀνάμνησις. According to Aristotle, Plato confounded the process of remembering with induction. The process of learning consists in the passing from opinion to knowledge. Aristotle’s theory as explained in the Posterior Analytics widely differs from Plato’s. In chapter 5, Bauman examines whether the syllogism based on a universal major is a petitio principii, a charge laid against it ever since antiquity and repeated by John Stuart Mill. For Mill, induction is the only form of real inference, but Bauman shows that Mill’s position is not correct. Aristotle sets up a method which allows us to understand why things are the way they are and to pass on knowledge. In chapter 6, Bauman compares Aristotle’s method with what teachers usually do and with how textbook authors conceive the passing on of knowledge. Some previous knowledge is necessary for all teaching. Aristotle focused on how the sciences should be taught, showing how conclusions are implicitly contained in principles or can be deduced from them. Bauman thinks that this is restricting learning far too much and remains unsatisfactory. He disagrees with Aristotle’s statement that all scientific knowledge is expressible in propositions in the indicative mood. The syllogism cannot be the only mode for all teaching. This difficulty, however, can be solved when one keeps in mind what strictly scientific knowledge in the Aristotelian sense is, and that there are other forms of knowledge such as opinion, factual knowledge, and dialectic. Furthermore one should also consider that the syllogism is basic to all forms of reasoning, even if there are syllogisms of different types. A printing mistake on page 191, line 13 should be corrected.—Leo J. Elders, Institute for Philosophy, “Rolduc,” Kerkrade, The Netherlands. (shrink)

In the paper, a detailed analysis of some new logical aspects of Cantor’s diagonal proof of the uncountability of continuum is presented. For the first time, strict formal, axiomatic, and algorithmic definitions of the notions of potential and actual infinities are presented. It is shown that the actualization of infinite sets and sequences used in Cantor’s proof is a necessary, but hidden, condition of the proof. The explication of the necessary condition and its factual usage within the framework of Cantor’s (...) proof makes, Cantor’s proof invalid. It’s shown that traditional Cantor’s proof has a second necessary, but hidden as well, condition which is teleological by its nature, i.e., is not mathematical. The explication of the second necessary condition makes Cantor’s statement on the uncountability of continuum unprovable from the point of view of classical logic.One of the most dramatic facts in history of science is connected just with the notion of actual infinity and consists in the following. On the one hand, Aristotle, Berkeley, Locke, Descartes, Spinoza, Gauss, Kant, Cauchy, Kronecker, Hermite, Poincaré, Bair, Borel, Brouwer, Quine, Wittgenstein, Weyl, Luzin, and a lot of other outstanding creators of classical logic and classical mathematics, during millenniums, stated categorically and insistently warned about that the actual infinity is a self-contradictory notion and its usage in mathematics is inadmissible (e.g., according to Poincare, “There is no actual infinity. - Cantorians forgot that and fell into contradictions. Later generations will regard Mengenlehre (set theory) as a disease from which one has recovered”). On the other hand, a lot of outstanding scientists of the XX c.c., such as Hilbert, Church, Turing, Gödel, etc., and modern axiomatic set theory as a whole ignored this (intuitive though) opinion of genii and accepted Cantor’s “transfinite paradise”, based on the actual infinity. In the paper some logical, philosophical, and psychological aspects of this historical “favorable opposition” are analyzed, and the fact that the scientific intuition of genii has won the historical battle against the mytho-’logic’ of Cantor’s transfinite ‘paradise’ is explained and logically justified.

This is a collection of papers already published (spanning the years from 1976 to 1998) covering Aristotle’s logic, his theory of science, his psychology, and his Ethics. Three papers are in English, six in German. The book contains an index of proper names as well as a list of Ebert’s publications up to 2002.

This volume contains the English translation of Felix Kaufmann's (1895-1945) main work Methodenlehre der Sozialwissenschaften (1936). In this book, Kaufmann develops a general theory of knowledge of the social sciences in his role as a cross-border commuter between Husserl's phenomenology, Kelsen's pure theory of law and the logical positivism of the Vienna Circle. This multilayered inquiry connects the value-oriented reflections of a general philosophy of science with the specificity of the methods and theories of the social sciences, as (...) opposed to abstract natural science and psychology. The core focus of the study is the attempt to elucidate how and under what conditions scientific knowledge about social facts, empirically justified and theoretically embedded, can be obtained. The empirical basis of knowledge within the social sciences forms a phenomenological concept of experience. According to Kaufmann, this concept of experience exhibits a complex structure. Within the meaning-interpretation of human action as the core of knowledge in the social sciences, this structure reaches out across the isolated act of verification toward the synthesis of external and internal experiences. The book opens with a detailed and useful introduction by Ingeborg K. Helling, which introduces the historical and theoretical background of Kaufmann's study and specifically illuminates his relation to Alfred Schütz and John Dewey. Finally, it contains interviews with and letters to members of his family, colleagues and students. (shrink)

David Earl Over is a leading cognitive scientist and, with his firm grounding in philosophical logic, he also exerts a powerful influence on the psychology of reasoning. He is responsible for not only a large body of empirical work and accompanying theory, but for advancing a major shift in thinking about reasoning, commonly known as the 'new paradigm' in the psychology of human reasoning. Over's signature mix of philosophical logic and experimental psychology has inspired generations of (...) researchers, psychologists, and philosophers alike over more than a quarter of a century. The chapters in this volume, written by a leading group of contributors including a number who helped shape the psychology of reasoning as we know it today, each take their starting point from the key themes of Over's ground-breaking work. The essays in this collection explore a wide range of central topics--such as rationality, bias, dual processes, and dual systems--as well as contemporary psychological and philosophical theories of conditionals. It concludes with an engaging new chapter, authored by David Over himself, which details and analyses the new paradigm psychology of reasoning. This book is therefore important reading for scholars, researchers, and advanced students in psychology, philosophy, and the cognitive sciences, including those who are not familiar with Over's thought already.

The nature of the human being in general and the existence and nature of the soul in particular has been discussed throughout the history of thought. As a knowing subject, man firstly tried to know himself. While making this questioning, he not only wondered about his phenomenal existence (body), but also about his spiritual identity, which he did not doubt was out there somewhere. This curiosity has created an ongoing scientific journey from anatomy to physiology, from science to philosophy, from (...) medicine to sociology, from biology to neurobiology, from psychology to neuropsychology, from chemistry to neurochemistry. In the end, various human conceptions have been developed in accordance with the scientific and philosophical background of each civilization. The ancient tradition of thought, which is the common accumulation of humanity, has largely included man in a dualist definition. Along with modern science, many devices have been developed to study human beings physically. Numerous data have been reached with the opportunities provided by technology, and these data have provided great usefulness in understanding what aspects a human being has in terms of physics and metaphysics. However, with the increase in our knowledge of the natural world and human, which is a part of it, the perspectives of the period were forced into paradigmatic changes. The philosophical movements that developed and changed in parallel with scientific knowledge, the decline of religion, especially in the Western world, regressed the dominant models in the interpretation of knowledge. Notions of human have inevitably taken their share from this great change. Is the subject behind the actions separate/independent from the body/brain and completely autonomous and rational? Or is it just the body/brain or its functionality, as modern neuroscience suggests? Does this coherent functionality arise entirely or in part from natural causation? Is there an essence or a distinctive feature that makes us human? If so, is this essence/property physical or is it a metaphysical substance? What answers did the early theologians give to these questions? What are the points of overlap between the hypotheses developed mainly on religious knowledge, partly on medical knowledge of the period via largely logical reasoning, and the definitions of human and soul revealed by contemporary experimental science? This line forms the main frame of the article. In summary, this study; It aims to identify the parallels and similarities of approach between the spiritual theories of the early theologians and current scientific data, which we see as two important phases of the ongoing ancient investigation. It is thought that the theories developed in this first period, when the transformation due to the acculturation process is not sufficiently determinative on thought, are more original and valuable. After giving brief information about the definitions of soul, mind, self and consciousness, which are among the basic concepts of the problem, the thoughts of early Mu‘tazilī and Ahl al-Sunnah thinkers on the subject are presented comparatively with current scientific data. We tried to make a healthy descriptive inference by making analytical and semantic arguments on the data obtained during the research. (shrink)

Within the context of psychological measurement, realist commitments pervade methodology. Further, there are instances where particular scientific practices and decisions are explicable most plausibly against a background assumption of epistemic realism. That psychometrics is a realist enterprise provides a possible toehold for Stephen Jay Gould’s objections to psychometrics in The Mismeasure of Man and Joel Michell’s charges that psychometrics is a “pathological science.” These objections do not withstand scrutiny. There are no fewer than three activities in ongoing psychometric research which (...) presuppose a commitment to a minimal epistemic realism. Those activities include selecting between different models for representing data, estimating ability in the context of item response theory, and the move to make the individual the fundamental unit of analysis in psychometrics thereby calling for a shift in what sorts of data are evidentially relevant. In none of these activities are the commitments and disregard for evidence that Gould and Michell find objectionable or “pathological.”. (shrink)

Determinist thought with its sui generis view on life, nature and being as a whole is a point of view that could be observed in many different cultures and beliefs. It was thanks to Greek thought that it ceased to be a cultural element and transformed into a systematic cosmology. Schools such as Leucippos, then Democritos and Stoa attempted to integrate the determinist philosophy into ontology and cosmology. In the course of time, physics and metaphysics-based determinism approaches were introduced, and (...) a wide spectrum has emerged from genetics to behaviorism, from culture to psychology, from atomism to divinity. Determinism, whether physical or metaphysical origin, ignores freedom of will and deny agency competence over human behavior. Due to this feature, it is opposed by ethical theories, legal philosophies and religions. When the arguments for determinism are possible to disprove logically and philosophically, this is not so easy when the claims base themselves on scientific base. As the logical consequence of this novel fact, it is important to question the epistemological value of scientific knowledge and critically analyze the data of experiments and clinical studies in terms of methodology when answering any hypothesis such as neuro-biological, neuro-psychological, or neuro-theological argumentations. On the other hand, it is necessary to reach alternative experiments on the same subject or to show that it is possible to interpret them in different ways, as in the example of the Libet experiment. The neurobiological determinism based on biological reductionism, emerged as the result of ignoring the ontological difference of the mind, equating the mind with the brain, or defining mentality as an epiphenomenon of the brain. The main divergence stems from the acceptance of materialist philosophy. Paradigms that reduce existence only to matter do not take the metaphysical possibilities into account. In this case, although the problems called qualia or subjective experience stand there unresolved, the claim is preserved. Although many new developments such as the discovery of the entropy law, the big bang theory, and quantum physics have shaken the materialist philosophy, modern science resists an epistemological revision. However, with the current epistemology, it does not seem possible to grasp both the universe and the being as a whole. This is the most important reason why every attempt to understand the nature and spiritual side of human beings fails despite numerous experiments on the brain. However, the human brain is an organ that seems sophisticated and its secrets cannot be easily solved. Since there is not enough information about the brain, there is not enough evidence to claim that the brain, and therefore the mind, are part of the deterministic universe. Increasing brain researches since the last quarter of the twentieth century has revealed that genes, neurons and particularly brain chemistry claim much greater role than expected in human behavior. These results have been instrumentalized by some researchers for a radical claim that free will is an illusion, while by others it has led to the acceptance of will as less important over actions than was thought. Both ideas adopted a model of biological determinism in which freedom of will was ignored. Hypotheses based on controversial interpretations of various experiments raised concerns about religious, moral, and legal responsibility. Although man cannot be thought of as a non-free being from the point of view of common sense, the smog screen over the truth would not be lifted unless the scientific data in question had a correct interpretation. At first glance, it seems unreasonable to discuss universal determinism in the quantum universe. Nevertheless, the claim that strong causality prevails in the material world, including consciousness, remains in place. Therefore, firstly criticizing determinism and then examining biological determinism will help to fix the conceptual framework. This article aims to explain why genetics and neurobiology, while acknowledging their importance in the realization of behavior, can’t completely abolish moral agency. Some hypotheses attribute consciousness and free will to the physico-shimic structure of the brain, the random activity of neurons, or the ability to automatically transform inputs into outputs with the advantage of genetic information. This is the most sensitive and important point of being human; it attacks free will. Paradoxically, while global civilization of our time promises infinite freedom to human beings the science of the same age tries to prove that it is not free. (shrink)

This is a book about Aristotle's philosophy of language, interpreted in a framework that provides a comprehensive interpretation of Aristotle's metaphysics, philosophy of mind, epistemology and science. The aim of the book is to explicate the description of meaning contained in De Interpretatione and to show the relevance of that theory of meaning to much of the rest of Aristotle's philosophy. In the process Deborah Modrak reveals how that theory of meaning has been much maligned. (...) This is a major reassessment of an underestimated aspect of Aristotle that will be of particular interest to classical philosophers, classicists and historians of psychology and cognitive science.

The Boston Colloquium for the Philosophy of Science began 2S years ago as an interdisciplinary, interuniversity collaboration of friends and colleagues in philosophy, logic, the natural sciences and the social sciences, psychology, religious studies, arts and literature, and often the celebrated man-in-the street. Boston University came to be the home base. Within a few years, pro ceedings were seen to be candidates for publication, first suggested by Gerald Holton for the journal Synthese within the Synthese Library, both from the (...) D. Reidel Publishing Company of Dordrecht, then and now in Boston and Lancaster too. Our colloquium was inheritor of the Institute for the Unity of Science, itself the American transplant of the Vienna Circle, and we were repeatedly honored by encouragement and participation of the Institute's central figure, Philipp Frank. The proceedings were selected, edited, revised in the light of the discussions at our colloquia, and then other volumes were added which were derived from other symposia, in Boston or elsewhere. A friendly autonomy, in dependent of the Synthese Library proper, existed for more than a decade and then the Boston Studies became fully separate. We were grateful to Jaakko Hintikka for his continued encouragement within that Library. The series Boston Studies in the Philosophy of Science was conceived in the broadest framework of interdisciplinary and international concerns. Natural scientists, mathematicians, social scientists and philosophers have contributed to the series, as have historians and sociologists of science, linguists, psychologists, physicians, and literary critics.

Recent studies on the philosophy of Avicenna have traditionally focused on his metaphysics, his psychology, and his influence on subsequent philosophers within.

In this short, dense essay, Jean Cavaillès evaluates philosophical efforts to determine the origin - logical or ontological - of scientific thought, arguing that, rather than seeking to found science in original intentional acts, a priori meanings, or foundational logical relations, any adequate theory must involve a history of the concept. Cavaillès insists on a historical epistemology that is conceptual rather than phenomenological, and a logic that is dialectical rather than transcendental. His famous call (cited by Foucault) to abandon (...) "a philosophy of consciousness" for "a philosophy of the concept" was crucial in displacing the focus of philosophical enquiry from aprioristic foundations toward structural historical shifts in the conceptual fabric. This new translation of Cavaillès's final work, written in 1942 during his imprisonment for Resistance activities, presents an opportunity to reencounter an original and lucid thinker. Cavaillès's subtle adjudication between positivistic claims that science has no need of philosophy, and philosophers' obstinate disregard for actual scientific events, speaks to a dilemma that remains pertinent for us today. His affirmation of the authority of scientific thinking combined with his commitment to conceptual creation yields a radical defense of the freedom of thought and the possibility of the new.

Some 2300 years ago, Hellenic Philosophy had already produced some rather sophisticated theories of human psychological functioning as well as most of the broad theoretical controversies which characterize the contemporary psychological stage. Democritus, for example, had put forth a theory of thinking and action which emphasized the physiological components of the person and looked to immediate environmental antecedents as explanations for what we did. Plato, by contrast, insisted upon the formal rule-governed characteristics of human thinking as basic to intellect (...) and denied the possibility that these could be acquired piecemeal through experience with environmental events. Nor would he accept the relevance of physiological descriptions for answering psychological questions. The following centuries have witnessed both the intensification of these controversies and their proliferation into new scientific and societal spheres, as intellectual fashions have favored now one and then another theoretic orientation. A resolution to many such controversies was proposed by Aristotle in the course of formulating his developmental and teleological doctrine of Man, and the logic of this mode of resolution still has great relevance today for the evaluation of psychological theories. In Aristotle's account, a new approach to the concept of causality evolved, an approach that paid special attention to how the term "causes" should be applied to biological events. Moreover, this approach to causality was highly successful in integrating biological phenomena with an understanding of the nature of causes for psychological phenomena. The explication of this account demonstrated that "why" explanations and "how" explanations of action could and should be used concurrently and also demonstrated that many psychological controversies were based on pseudo-issues. This approach, and particularly its relevance to developmental psychology, will be outlined here. 2012 APA, all rights reserved). (shrink)

It is fashionable now-a-days to regard Aristotle’s logic as being the skeleton in the closet of Aristotelian philosophy. As Miss Anscombe has acidly remarked, “Aristotle himself … misconceived the importance of the categorical syllogism, supposing that the theory of it gave him the key to the nature of scientific knowledge. He expresses this view in what I find his worst book: Book I of the Posterior Analytics.”.

Over the course of a career that has spanned more than fifty years, philosopher Fred Sommers has taken on the monumental task of reviving the development of Aristotelian (syllogistic) logic after it was supplanted by the predicate logic of Gottlob Frege and Bertrand Russell. The enormousness of Sommers's undertaking can be gauged by the fact that most philosophers had come to believe - as David S. Oderberg writes in his preface - that "Aristotelian logic was good but is now as (...) good as dead." A revival of traditional syllogistic logic would involve not only its restatement but its refashioning into a system that could rival the elegance and deductive power of predicate logic. Building on work by medieval scholastic logicians, Leibniz, and nineteenth-century algebraic logicians, Sommers accomplished this renovation and rehabilitation of syllogistic logic with his magnum opus The Logic of Natural Language, published in 1982. In The Old New Logic, essays by a diverse group of contributors show how widely influential Sommers's work has been-not only in logic, but in category theory and other areas. Scholars in psychology, linguistics, and computer science join philosophers and logicians in discussing aspects of Sommers's contributions to philosophy. Sommers himself provides an intellectual autobiography at the beginning and in the final chapter offers comments on the contributions. This collection should help bring to Sommers's work the attention it deserves from the wider philosophical and intellectual community. (shrink)

This edition provides the first complete English translation of Bernard Bolzano's four-volume Wissenschaftslehre or Theory of Science, a masterwork of theoretical philosophy. First published in 1837, the Wissenschaftslehre is a monumental, wholly original study in logic, epistemology, heuristics, and scientific methodology. Unlike most logical studies of the period, it is not concerned with the "psychological self-consciousness of the thinking mind." Instead, it develops logic as the science of "propositions in themselves" and their parts, especially the relations between these entities. (...) It offers, for the first time in the history of logic, a viable definition of consequence, and a novel view of probability. Giving constant attention to Bolzano's predecessors and contemporaries, with particular emphasis on Kant, this richly documented work is also a valuable source for the history of logic and philosophy.

In this book, experts from the fields of law and philosophy explore the works of Aristotle to illuminate the much-debated and fascinating relationship between emotions and justice. Emotions matter in connection with democracy and equity – they are relevant to the judicial enforcement of rights, legal argumentation, and decision-making processes in legislative bodies and courts. The decisive role that emotions, feelings and passions play in these processes cannot be ignored – not even by those who believe that emotions have no (...) legitimate place in the public sphere. A growing body of literature on these topics recognizes the seminal insights contributed by Aristotle. This book offers a comprehensive analysis of his thinking in this context, as well as proposals for inspiring dialogues between his works and those written by a selection of modern and contemporary thinkers. As such, the book offers a valuable resource for students of law, philosophy, rhetoric, politics, ethics and history, but also for readers interested in the ongoing debate about legal positivism and the relevance of emotions for legal and political life in today’s world.

Moral theories may differ not only in the substantive moral principles they assert, but also in their concept of a person or moral agent. Thus, for example, Utilitarianism stresses the ability of a human being to calculate rationally the profit and loss which attend particular actions; and Aristotle bases his Nichomachean Ethics on a moral psychology tied to the notion of harmonious self-development.

The present book is the English version of a monograph 'Die aristotelische Syllogistik', which first appeared ten years ago in the series of Abhand 1 lungen edited by the Academy of Sciences in Gottingen. In the preface to the English edition, I would first like to express my indebtedness to Mr. J. Barnes, now fellow of Oriel College, Oxford. He not only translated what must have been a difficult text with exemplary precision and ingenuity, but followed critically every argument and (...) check ed every reference. While translating it, he has improved the book. Of those changes which I have made on Mr. Barnes' suggestion I note only the more important ones on pages 4, 12, 24sq, 32, 39, 6lsq, and 158. Since the second edition of the German text appeared in 1963 some further reviews have been published, or come to my notice, which I have 2 been able to make use of in improving the text of this new edition. I must mention here especially the detailed critical discussions of my results and arguments published by Professor W. Wieland in the Philosophische Rundschau 14 (1966), 1-27 and by Professor E. Scheibe in Gnomon 39 (1967), 454-64. Both scholars, while agreeing with the main drift and method of my interpretation, criticise some of my results and disagree with some of my arguments. It would not be possible to discuss these technical matters here with the necessary thoroughness. (shrink)

Aristotle takes practical wisdom and arts or crafts to be forms of knowledge which, we argue, can usefully be thought of as ‘empiricist’. This empiricism has two key features: knowledge does not rest on grasping unobservable natures or essences; and knowledge does not rest on grasping logical relations that hold among propositions. Instead, knowledge rests on observation, memory, experience and everyday uses of reason. While Aristotle’s conception of theoretical knowledge does require grasping unobservable essences and logical relations that hold among (...) suitable propositions, his conception of practical and productive knowledge avoids such requirements and is consistent with empiricism.

In this provocative contribution to both psychoanalytic theory and the philosophy of science, Louis Berger grapples with the nature of "consequential" theorizing, i.e., theorizing that is relevant to what transpires in clinical practice. By examining analysis as a genre of "state process formalism" - the standard format of scientific theories - Berger demonstrates why contemporary theorizing inevitably fails to explain crucial aspects of practice. His critique, in this respect, pertains both to the formal structure of psychoanalytic explanation and the (...) technical language through which this structure gains expression. The pragmatic recommendations that issue from this critique are illustrated with respect to a number of perennial problem areas besetting analysis and cognate disciplines. In a discussion that encompases theories of affect, issues in family therapy, the nature of first-language acquisition, and the philisophical topics of free will and determinism, Berger shows that certain systems of representation _can_ describe the psychological realm adequately, and that such systems necessarily follow modern physics in rejecting naive assumptions about the separability of theory and practice. His proposals culminate in a "nonhierarchical" conception of psychoanalytic theory that assigns a separate status to the clinically pragmatic level of theorizing. In both his critique of contemporary analysis and his reconstructive proposals, Berger fuses into a highly readable argument a fascinating range of insights culled from epistemology, linguistics, physics, logic, computer science, history, and aesthetics. More impressively still, he demonstrates how an investigation of psychoanalytic theory can serve as a vehicle for examining pervasive epistemological issues in both philosophy and the social sciences.

Today, there are many natural sciences, one of which is physics, but there is no science in the sense of a Theory of Nature. In our everyday life, the opinion is rightly held that there is only one nature, but whether this opinion stands up to reflection is questionable. When we apply the speculation that Aristotle developed in Metaphysics Λ to his Physics, we will see, that Aristotle has developed a Theory of Nature that consists in posing the (...) question of the being of the natural being (Frage nach dem Sein des Naturseienden). The standardinterpretation wants us to believe that Aristotle founded a substance metaphysics with a corresponding theology, and that he practised natural science. But, our hermeneutical situation could lead us to an "Aristotle today" and free us from old beliefs so that we, like Thomas Aquinas and others, could learn from a contemporary Aristotle as an immediate interlocutor. One of the learning points, for example, would be that questions are more crucial than new assertions, even if they are sophisticated, and that unassertive thinking (unbehauptendes Denken) in a topical attitude can lead us to insight into the multiplicity of worlds. This insight would have immediate consequences for our behaviour towards our co-inhabitants of our planet and towards our environment. (shrink)

Purpose. The paper is aimed at studying the specificity of anthropological problematics in pragmatism from the perspective of its ability to be the source of analytic philosophy evolution in the socio-humanitarian direction. Theoretical basis of the research is determined by the works of the representatives of classical pragmatism, neopragmatism, post-pragmatism and analytic pragmatism. Their works give a clear understanding of the important place of anthropological searches in the theory of pragmatism. Originality. On the basis of the analysis of logical, (...) epistemological and metaphysical ideas formulated by representatives of pragmatism, it is proved that pragmatic methodology is anthropocentric. It is established that the ideological and social foundations of pragmatism can be determined as pluralistic ones due to the attention to the human person. It is revealed that theoretical and methodological searches of pragmatism can be effective in the formation of the socio-humanitarian concepts in analytic philosophy through the specification of strategies for the cognition of human existence in such terms as experience or self and the development of practical ways to justify the truth of knowledge. Conclusions. Pragmatists criticized impersonal, formal thinking, which cannot be an effective means of cognition. Thinking has a social basis and is entirely personal. Justifying its dependence on the socio-cultural sphere and the internal intentions of the subject, it is possible to develop an effective logical theory that operates symbols not only at the syntactic or semantic level but also takes into account the pragmatic aspect of language. Anthropological problematics is also important in the theory of knowledge, the core of which is the notion of pragmatic belief, which enables truth and religious beliefs, since the foundation of the theory of truth is determined by the principle of humanism, and the truth is interpreted as a value orientation. Knowing the external world, we find in it the similarity with us – that’s why the metaphysical foundations of being, according to pragmatism, are personified, and the methodology is defined in anthropomorphic terms. Applying it, the study of human existence is specified in the analysis of psychological and socio-cultural dimensions of such concepts as experience or self. Attempts to comprehend the nature of human existence in pragmatism are empirically grounded. Appealing to science, methodological pluralism, the search for socio-cultural background for thinking and suitable linguistic forms of expression of human experience are the achievements of pragmatism, which are the basis for the socio-humanitarian redescription of analytic methodology.

Santayana's Life of Reason, published in five books from 1905 to 1906, ranks as one of the greatest works in modern philosophical naturalism. Acknowledging the natural material bases of human life, Santayana traces the development of the human capacity for appreciating and cultivating the ideal. It is a capacity he exhibits as he articulates a continuity running through animal impulse, practical intelligence, and ideal harmony in reason, society, art, religion, and science. The work is an exquisitely rendered vision of human (...) life lived sanely. In this first book of the work, Santayana provides an account of how the human animal develops instinct, passion, and chaotic experience into rationality and ideal life. Inspired by Aristotle's De Anima, Darwin's evolutionary theory, and William James's The Principles of Psychology, Santayana contends that the requirements of action in a hazardous and uncertain environment are the sources of the development of mind. More specifically, instinct and imagination are crucial to the emergence of reason from chaos. Separating himself from the typical thought of the time by his recognition of the imagination, Santayana in this volume offers extensive critiques of various philosophies of mind, including those of Kant and the British empiricists. This Critical Edition, volume VII of The Works of George Santayana, includes a chronology, notes, bibliography, textual commentary, lists of variants, and other tools useful to Santayana scholars. The other four books of the volume include Reason in Society, Reason in Religion, Reason in Art, and Reason in Science. (shrink)

While nowhere does he use the term to refer to his own theory, Aristotle is often thought to exemplify an early correspondence theory of truth. In the paper, I examine the textual evidence used to support the idea that Aristotle holds a correspondence theory of truth, and to infer the nuances of this theory. I hold that Aristotle’s theory of truth can account for terms that signify non-existent things, i.e., that on Aristotle’s account, an assertion (...) is not automatically false given its subject term’s “failure to refer”. Terms do not refer for Aristotle, they signify. (shrink)

Aristotle’s modal syllogistic is his study of patterns of reasoning about necessity and possibility. Many scholars think the modal syllogistic is incoherent, a ‘realm of darkness’. Others think it is coherent, but devise complicated formal modellings to mimic Aristotle’s results. This volume provides a simple interpretation of Aristotle’s modal syllogistic using standard predicate logic. Rini distinguishes between red terms, such as ‘horse’, ‘plant’ or ‘man’, which name things in virtue of features those things must have, and green terms, such as (...) ‘moving’, which name things in virtue of their non-necessary features. By applying this distinction to the Prior Analytics, Rini shows how traditional interpretive puzzles about the modal syllogistic melt away and the simple structure of Aristotle’s own proofs is revealed. The result is an applied logic which provides needed links between Aristotle’s views of science and logical demonstration. The volume is particularly valuable to researchers and students of the history of logic, Aristotle’s theory of modality, and the philosophy of logic in general. (shrink)

This is the most interesting contemporary study of Aristotle’s syllogistic I have seen. The author combines a genuine insight into Aristotle’s way of thinking with a useful grasp of contemporary logical theory. He uses contemporary notions like compactness, completeness, consistency, and the like in such a way as genuinely to illuminate Aristotle’s thought, rather than to obfuscate it or to reduce classical patterns of reasoning to those of our day. In other words, he shows how Aristotle’s central doctrines are (...) in many cases anticipations of contemporary concepts, thereby establishing a continuity in logical theory which goes at least some steps toward mitigating the effects of historicism in the domain of the history of logic. His style is as lucid as the subject-matter permits. The book is accessible to anyone with a minimum knowledge of syllogistic and some of the central notions of present-day metamathematics. Not the least helpful feature of the book is its quiet correction of errors made by the author’s predecessors in the analytical tradition’s attempt to assimilate Aristotle into current technical procedures.

For the second edition, the translation has been completely rewritten and the commentary has been thoroughly revised in the light of recent scholarship.

Due to the current availability of the English translation of almost all of Lesniewski's works it is now possible to give a clear and detailed picture of his ideas. Lesniewski's system of the foundation of mathematics is discussed. In abrief ouüine of his three systems Mereology, Ontology and Protothetics his positions conceming the problems of the forms of expression, proper names, synonymity, analytic and synthetic propositions, existential propositions, the concept of logic, and his views of theory of science and (...) metaphysics are sketched. The influence of Mill, Lukasiewicz, Austrian philosophy and especially Petrazycki on his thinking is evaluated and an interpretation is suggested setting him squarely in a tradition of classical Aristotelian logic.

As a result of this case study, additional questions arise. These can be cast into at least three groups. The first concerns the development of critical empiricism in the ancient world: a topic of much interest in our own century, expecially with regard to the work of the logical empiricists. Many of the same arguments are present in the ancient world and were hotly debated from the Hippocratic writers through and beyond Galen. Some of the ways in which Galen reacts (...) to Hippocratic and Aristotelian influences may, in part, be explained by Galen's own posture as a so-called Dogmatist. Both the Empirics and the Methodists offered alternative viewpoints on the place, role, and limits of observation in biomedical research. Though I have written on this relationship in the Hippocratic writers and Aristotle,44 it remains to be discussed in detailed fashion just how critical empiricism acted in Galen's evaluation of biomedical problems (aporiai). Contrasts between Galen and his predecessors might further clarify this issue both as a historical question and as it affects the construction of biological theory.The second area explores the question of how one develops comprehensive theories. In this respect Galen follows Aristotle's methodology rather closely. Both look at what theories are available to them and then systematically review the problems raised, at the same time refuting what they find inadequate. This is an effective strategy, for it permits utilizing the best features of earlier work to fashion a new whole. Indeed, Galen himself seems to attribute his use of such a methodology to his “ecletic” medical and philosophical training. Both Aristotle and Galen endeavor to employ techniques of theory integration. That is, they use aspects of theories they have already espoused to deal with new problems. This suggests the emergence of formal, logical coherence as an element in theory evaluation. The obvious drawback is that it can cause mistakes in one area to be repeated and ingrained in other areas. Such errors, because they are at the very core of an explanatory framework, may take centuries to correct. Future studies may shed light on how theory integration acts both in a positive and in a negative way.Finally, this case study offers a glimpse of how science progresses. Even though the advances in medical technology were comparatively minor, there is a great deal more sophistication in the conception theoreis of Aristotle and Galen than was present in the Hippocratic writers. Some of this (in Galen's case) had to do with increased anatomic and physiological knowledge, but most, I believe, is due to the evolution of scientific knowledge. If further work were done specifically on this question, it might document more completely how scientific knowledge on a specific topic evolves. The mode of advancement is primarily through gradual refinement of the types of questions being asked by these ancient authors, and the ramifications of their answers.Ancient theories of conception offer a fine case study in the history and philosophy of how a theory begins the develops. I have tried to suggest some interrelationships among the more important theories, as they focused upon Aristotle's own conception theory. There has been renewed interest in such cases in recent years. It is my hope that future specialized studies will increase our knowledge of method and practice in these important case studies and thereby augment our understanding of the genesis and application of biological theories.

Through a detailed analysis of the various modes of argumentation employed by Aristotle throughout his natural scientific works, I aim to contribute to the growing scholarship on the relation between Aristotle’s theory of science and his actual scientific practice. I challenge the standard reading of Aristotle as a methodological empiricist and show that he permits a variety of non-empirical arguments to support controversial theses in properly scientific contexts. Specifically, I examine his use of logical (logikôs) argumentation in the discussion (...) of mule sterility in Generation of Animals II 8, rational (kata ton logon) argumentation in his discussion of cardiocentrism throughout the biological works, and the method of division in Posterior Analytics II 13.

I offer a novel interpretation of Aristotle's psychology and notion of rationality, which draws the line between animal and specifically human cognition. Aristotle distinguishes belief (doxa), a form of rational cognition, from imagining (phantasia), which is shared with non-rational animals. We are, he says, “immediately affected” by beliefs, but respond to imagining “as if we were looking at a picture.” Aristotle's argument has been misunderstood; my interpretation explains and motivates it. Rationality includes a filter that interrupts the (...) pathways between cognition and behavior. This prevents the subject from responding to certain representations. Stress and damage compromise the filter, making the subject respond indiscriminately, as non-rational animals do. Beliefs are representations that have made it past the filter, which is why they can “affect [us] immediately.” Aristotle's claims express ceteris paribus generalizations, subject to exceptions. No list of provisos could turn them into non-vacuous universal claims, but this does not rob them of their explanatory power. Aristotle's cognitive science resolves a tension we grapple with today: it accounts for the specialness of human action and thinking within a strictly naturalistic framework. The theory is striking in its insight and explanatory power, instructive in its methodological shortcomings. (shrink)

This book addresses the fundamentals of machine ethics. It discusses abilities required for ethical machine reasoning and the programming features that enable them. It connects ethics, psychological ethical processes, and machine implemented procedures. From a technical point of view, the book uses logic programming and evolutionary game theory to model and link the individual and collective moral realms. It also reports on the results of experiments performed using several model implementations. Opening specific and promising inroads into the terra incognita (...) of machine ethics, the authors define here new tools and describe a variety of program-tested moral applications and implemented systems. In addition, they provide alternative readings paths, allowing readers to best focus on their specific interests and to explore the concepts at different levels of detail. Mainly written for researchers in cognitive science, artificial intelligence, robotics, philosophy of technology and engineering of ethics, the book will also be of general interest to other academics, undergraduates in search of research topics, science journalists as well as science and society forums, legislators and military organizations concerned with machine ethics.

During the Middle Ages and Rennaissance, it was commonly believed that Aristotle's biological studies reflected his theory of demonstrative science quite well. By contrast, most commentators in the twentieth century have taken it that this is not the case. This is largely the result of preconceptions about what a natural science modelled after the proposals of Aristotle's Posterior Analytics would look like. I argue that these modern preconceptions are incorrect, and that, while the Analytics leaves a variety (...) of issues unanswered that a practicing biology must have answers to (hence Parts of Animals I), Aristotle's biological practice conforms to the Analytics model. It is further argued that establishing this claim requires reading philosophically through entire biological treatises--that is, one will miss the logical structure by following the usual practice of 'sampling' these treatises rather than reading them systematically.

In De Partibus Animalium I Aristotle sets out his philosophy of biology, discussing cause, necessity, soul, genus, and species, definition by logical division, and general methodology. In De Generatione Animalium I he applies his hylomorphic philosophy to the problem of animal reproduction. The translation is close, and includes passages from De Generatione Animalium II which complete Aristotle's theory of reproduction. The notes interpret Aristotle's arguments and discuss his views on major issues such as natural teleology. The original (...) edition was published in 1972. (shrink)

Physics IV.10 (217b30–218a30) is pivotal in Aristotle’s discussion of time, preceding his own account from IV.11 onward. Aristotle presents three puzzles about the existence of time with reference to the “Now”. Modern interpretations often view this section as an aporetic prelude with Aristotle’s failure to provide explicit solutions. This paper examines Simplicius’ alternative interpretation, which draws upon the theory of proof and the syllogistic model from the Posterior Analytics. Simplicius contends that the arguments’ failure lies in their inability to (...) fit within the suitable syllogistic framework to establish a demonstrable definition of time, not in their aporetic nature. Every science has to prove the relation between (i) establishing whether X exists and (ii) showing what X is by establishing what the cause of X is. In evaluating Simplicius’ interpretation, this paper addresses two key aspects of the exegesis of IV.10: firstly, Simplicius can show why the “Now” is not part of the definition of time, and secondly, the ancient commentator underscores the close connection between the arguments in Physics IV.10 and the broader context of Aristotle’s discussion of time. Modern interpreters fail to address both of these issues. (shrink)

Aristotle’s biology is based on his method of division of animal kinds by multiple differentiae. This results in complex clusters of non-subordinate terms, between which Aristotle seeks to establish universal correlations. The form of these, however, does not correspond to that prescribed by his theory of syllogism. Mereological relations between terms are not linear and quantification is far more complex than the distinction between universal and particular propositions. Thus the axiomatisation of Aristotle’s biology requires a tool designed for analysing (...) such complex universal correlations into valid syllogistic premises. Prosleptic-like premises turn out to be the solution outlined by Aristotle. They make it possible to handle both the logic of consequence which translates from and into mereological relations between term clusters, and the complex quantification required by division based on multiple differentiæ, through the instantiation of a variable ideally consisting of indivisible groups of animals.

This article demonstrates that Ibn Sīnā’s theory of experience (taǧriba) requires a cross-reference between logic and psychology. Following the Basran linguistic tradition, he paraphrases derived names (ism muštaqq) into the li-x y formula: for example, ʿālim (“knowing”) is paraphrased into lahu ʿilm (“an act of knowing belongs to him”). His theory of experience employs this formula for arranging observed phenomena into a certain form of a syllogism and describing functions of the brain’s inner senses. Ibn Sīnā arranges (...) observed phenomenon into the li-x y formula or the proposition of which a predicate is a derived name of y. Meanwhile, he holds that the sense of recollection is involved in the process of experience. Recollection is an inner sense of the brain, which preserves maʿnā perceived by the sense of estimation. Estimation means to perceive maʿnā (y) that inheres in a subject (x), and to make a judgment about x based on y. Thus, in this process, the analysis of derived names arranges observed phenomena into a rational order, and the inner sense establishes the causation between apprehension and logical assertion. The article concludes by discussing the relation of this philosophy to medicine. (shrink)

This book aims to provide an introduction to Aristotle's Politics, highlighting the major themes and arguments offered in the scholar's work. It begins with a discussion on what Aristotle perceives as human good, which he had described as the ethical purpose of political science, and how he views the political community, or the polis, as a community of persons formed with a view to some good purpose and a supreme entity in the sense that it is not just one (...) aspect of city-state society but is the whole of that society. The book also discusses Aristotle's arguments against the abolition of the household for the ruling class and the communism of families and property, which Plato advocates, and highlights certain inconsistencies and vulnerabilities in his arguments supporting natural slavery and on how the husband should rule over his wife and children. The book presents Aristotle's account of the relative merits of six different types of constitution and his views on the best possible constitution that will help in the realization of the polis' true purpose of achieving the good life. It ends with a discussion on Aristotle's view of political science in relation to the protection of particular constitutions against constitutional change and political disorder. (shrink)
