Few interpreters of Aristotle have denied that both empirical, inductive methods and some kind of systematic deduction played a role in the philosophy of the biologist who expounded the West's first formal logic. But it has usually been the fashion to focus on one side of this polarity. In recent decades the focus has been on the empirical Aristotle. But some of the latest studies emphasize that Aristotle varied his methods according to context. G. E. L. Owen, for example, although (...) he feels that Aristotle took little care to separate inductive and deductive methods in the treatises, does allow that he uses deduction at times, and mentions book 6 of the Physics among them.

In lieu of an abstract, here is a brief excerpt of the content:Ghazali and Demonstrative Science MICHAEL E. MARMURA I MEDIEVALISLA_MICtheologians subjected Aristotle's theory of the essential efficient cause to severe criticism and rejected it. This criticism and rejection finds its most forceful expression in the writings of Ghazali (al-Ghaz~li) (d. 1111).1 In his Tahafut al-Falasifa (The Incoherence of the Philosophers), he argues on logical and empirical grounds that the alleged necessary connection between what is habitually regarded as (...) the natural efficient cause and its effect cannot be proven. He does not, however, take an agnostic stand on this question but proceeds to affirm two points: (1) that there is no causal agency in natural things; (2) that all natural events are the direct creation of God. Ghazali, moreover, does not confine such divine action to the realm of the inanimate and the irrational, in his al-Iqtis.~d fi-l-Ftiqad (The Golden Mean of Belief), he affirms the doctrine that the individual human act, like any other occurrence in the world, is also the direct creation of God. Causal efficacy resides in God alone. But the divine act, for Ghazali, is not an essential act. It does not proceed as the necessary consequence of divine essence. It is the arbitrary decree of the divine will, an attribute coeternal, but not identical with divine essence. Ghazali thus denies essential action altogether. In all this, he gives expression to the occasionalism of the Islamic school of dogmatic theology (kal~m) to which he belonged, the Ashcarite school. Ghazali had also a keen interest in logic. He wrote logical treatises for his fellow theologians, encouraging them to master this art as a tool to rebutt their doctrinal opponents. The~ treatises, in the main, sum up and explain the logic used by the Islamic philosophers--a logic that reflects the Stoic and Aristotelian traditions. Ghazali recognizes formal logic to be philosophically neutral, and hence in no way conflicting with his theology." He does not confine himself to formal logic in these expositions, however, but discusses Aristotelian demonstration. And it is in his statements on demonstration that we seem to be confronted with paradox. Demonstrative science, as understood by the Islamic philosophers, rests on the theory of essential causes and functions in terms of it. Indeed, in his reply to Ghazali's rejection of essential efficient causes in nature, Averroes (Ibn Rushd) (d. 1198) argues Texts frequently referred to in the notes will be abbreviated as follows: Demonstration: Ibn Sin~, Al-Shifa~; Logic V.; Demonstration, ed.

We would have no true knowledge; at best, only opinion. 3For this staunch defender of Aristotle, the theory of natural efficient causality constitutes a necessary condition for demonstrative science. Yet Ghazali in his writings does not deny the claim that demonstration gives us certain knowledge about the natural order. On the contrary, he seems to be affirming this in both his Tahdfutand the logical treatise he appended to this work, Mi~jdral-CIlm(The Standardfor Knowledge).If Ghazali does in fact uphold this claim for demonstration, then he must either deny that the theory of essential efficient causality is a necessary condition for demonstrative science, or fall into contradiction. At first glance, Ghazali's position in the Micy~r,where he gives his most comprehensive treatment of demonstration, is highly ambiguous and suggests contradiction. He seems for the most part to be reproducing the essentials of the Aristotelian demonstrative theory. Although in one section he reaffirms his rejection of necessary causal connection in nature, he nonetheless continues to use such terms as "cause," "effect," "necessity" and "certainty" in what appear to be...

By a thorough study of the Posterior Analytics and related Aristotelian texts, Richard McKirahan reconstructs Aristotle's theory of episteme--science. The Posterior Analytics contains the first extensive treatment of the nature and structure of science in the history of philosophy, and McKirahan's aim is to interpret it sympathetically, following the lead of the text, rather than imposing contemporary frameworks on it. In addition to treating the theory as a whole, the author uses textual and philological as well as philosophical (...) material to interpret many important but difficult individual passages. A number of issues left obscure by the Aristotelian material are settled by reference to Euclid's geometrical practice in the Elements. To justify this use of Euclid, McKirahan makes a comparative analysis of fundamental features of Euclidian geometry with the corresponding elements of Aristotle's theory. Emerging from that discussion is a more precise and more complex picture of the relation between Aristotle's theory and Greek mathematics--a picture of mutual, rather than one-way, dependence.

This paper explores how scientific knowledge is used in a criminal case. I examine materials from an admissibility hearing in a murder trial and discuss the dynamics of contesting expert scientific opinion and evidence. The research finds that a purported form of “science” in the relevant scientific community is filtered through, tested by, and subjected to legal standards, conceptions, and procedures for determining admissibility. The paper details how the opposing lawyers, the expert witness, and the judge vie to contingently (...) work out what will count in court as appropriate scientific authority, methods and evidence, and as a scientifically valid and legally admissible account of “reasonable fear.” When science becomes enmeshed in legal controversies, science does not trump law. Rather, it is the court’s canons of proper procedure and measures of substantive adequacy that take precedence. (shrink)

Four instances of how science fiction contributes to the elucidation of novelty in the context of discovery are considered by extending existing discussions on temporal and use-novelty. In the first instance, science fiction takes an already well-known theory and produces its own re-interpretation; in the second instance, the scientific account is usually straightforward and whatever novelty that may occur would be more along the lines of how the science is deployed to extra-scientific matters; in the third instance, (...) science fiction takes an idea that appears impossible within the delimitations of reality and produces a universe where such a possibility becomes feasible; and in the fourth instance, science fiction extends from an idea already known at the time of the work’s production to simulate a possibility that could emerge should the extension be experimentally viable. However, the article will not end with a mere evaluation of these instances, but also proposes instances on how science fiction could contribute to new ways of experiencing, discerning, and working with scientific knowledge.

The essays in this volume reflect the wide-ranging interests of John D. North, distinguished historian of science and philosophy.

The reception of the rational sciences, scientific practice, discourse and methodology into Arabic Islamic society proceeded in several stages of exchange with the transmitters of Iranian, Christian-Aramaic and Byzantine-Greek learning. Translation and the acquisition of knowledge from the Hellenistic heritage went hand in hand with a continuous refinement of the methods of linguistic transposition and the creation of a standardized technical language in Arabic: terminology, rhetoric, and the genres of instruction. Demonstration more geometrico, first introduced by the paradigmatic sciences-mathematics, astronomy, (...) mechanics-and adopted by philosophers embracing the cosmology of Neoplatonism, was complemented and superseded by the methods of syllogistic demonstration. Faced with the establishment of philosophy as a demonstrative science, which claimed absolute and universal knowledge, even the hermeneuti. (shrink)

Le rôle de Haüy comme 'grand législateur de la minéralogie', pour reprendre le jugement de Cuvier, a laissé dans l'ombre son activité dans le domaine de l'électricité. Il est vrai que le phénomène découvert par Haüy — l'électricité de pression — a perdu son intérêt pour les physiciens à la fin du XIXe siècle. C'est l'analyse de l'évolution des attitudes de Haüy envers l'électricité qui présente pour nous de l'intérêt en ce qu'elle permet de mieux comprendre la puissance, et l'ambiguïté, (...) du mouvement collectif qui bouleverse la physique française de la fin du xviiie siècle, mouvement dont il fut un acteur majeur . Dans les années 1770, ce religieux se comporte comme tous les amateurs d'électricité en démontrant publiquement ses propriétés spectaculaires . Lorsqu'il se consacre à fonder la cristallographie sur la géométrie, il n'oublie pas les amateurs de minéraux ; il leur propose une classification simplifiée des cristaux suivant leurs propriétés électriques, propriétés à établir avec des instruments électriques qualitatifs. Mais lorsque Coulomb fait connaître sa loi fondamentale de l'électricité, appuyée sur une expérience hautement technique et de grande sensibilité, Haüy se convertit à cette nouvelle science de l'électricité. Bien que non mathématicien et étranger à ce type d'expérience — c'est là que réside l'ambiguïté — Haüy se fait l'ardent diffuseur de cette électricité radicalement nouvelle qui rejette les amateurs hors du champ de la science. Devenu membre reconnu de la communauté physico-mathématique parisienne, Haüy s'est parfaitement intégré dans la démarche mise en avant par ses confrères de l'Académie, Lavoisier, Laplace ou Coulomb, et a définitivement quitté le royaume des amateurs de cristaux ou d'étincelles.

The ideas of continental philosopher Martin Heidegger have been influential in cognitive science and artificial intelligence, despite the fact that there has been no effort to analyze these ideas empirically. The experiments reported here are designed to lend empirical support to Heidegger’s phenomenology and more specifically his description of the transition between ready-to-hand and unready-to-hand modes in interactions with tools. In experiment 1, we found that a smoothly coping cognitive system exhibits 1/fβ type positively correlated noise and that its (...) correlated character is reduced when the system is perturbed. This indicates that the participant and tool constitute a self-assembled, extended device during smooth coping and this device is disrupted by the perturbation. In experiment 2, we examine the re-organization of awareness that occurs when a smoothly coping, self-assembled, extended cognitive system is perturbed. We found that the disruption is accompanied by a change in attention which interferes with participants’ performance on a simultaneous cognitive task. Together these experiments show that a smoothly coping participant-tool system can be temporarily disrupted and that this disruption causes a change in the participant’s awareness. Since these two events follow as predictions from Heidegger’s work, our study offers evidence for the hypothesized transition from readiness-to-hand to unreadiness-to-hand. (shrink)

This book makes available for the first time an English translation of William of Ockham's work on Aristotle's _Posterior Analytics_, which contains his theory of scientific demonstration and philosophy of science. John Lee Longeway also includes an extensive commentary and a detailed history of the intellectual background to Ockham's work. He puts Ockham into context by providing a scholarly account of the reception and study of the _Posterior Analytics_ in the Latin Middle Ages, with a detailed discussion of Robert (...) Grosseteste, Albert the Great, Thomas Aquinas, Duns Scotus, and Giles of Rome. In a series of appendices, Longeway includes shorter translations of some important related work by Giles of Rome and John of Cornwall. In his introductory discussion, Longeway examines the exact character of the highest sort of demonstration, the relations of the empirical sciences to mathematics, natural causation and the manner in which natural laws come to be known, the possibility of natural knowledge, our knowledge of God, and the relation of theology to the other sciences. Longeway discusses the way in which scientific epistemology and theory of demonstration corresponds to the metaphysical position of its interpreter, in particular to the Neoplatonism of Grosseteste, the radical Aristotelianism of Giles of Rome and Albert the Great, the more moderate Aristotelianism of Aquinas, and the nominalistic empiricism of Ockham. Throughout the book, Longeway makes a case for Ockham's importance as the founder of empiricism in the West. _ “The present work is the result of decades of study of Ockham's philosophy of science. The translation and commentary are introduced by a chapter in which Longeway presents an overview of Ockham's thought in this area and highlights its philosophical significance. This introduction is in its own right a significant contribution to the history of philosophy.” — Owen Goldin, Marquette University_ "Like much else in medieval philosophy, medieval theories of demonstrative knowledge are historically important, philosophically interesting, and little understood. There are a few extensive studies into medieval discussions of demonstration and even fewer translations of these important discussions. Longeway's_ Demonstration and Scientific Knowledge in William of Ockham_ is, therefore, an important contribution to the field. This work contains not only an extensive set of translations of Ockham's work on the theory of demonstration, but also a book-length introduction in which Longeway surveys the development of medieval theories of demonstration prior to Ockham and situates Ockham's discussion within that development. The book will be of value to any scholar interested in Ockham's thought as well as to anyone interested more generally in medieval discussions of demonstration, science, and epistemology." —_Susan Brower-Toland, Saint Louis University_.

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)

It is argued in this paper that the valid argument forms coming under the general heading of Demonstrative Induction have played a highly significant role in the history of theoretical physics. This situation was thoroughly appreciated by several earlier philosophers of science and deserves to be more widely known and understood.

How can we explain our capacity to think about particulars in our external environment? Many philosophers have answered this question in terms of a sophisticated conception of space and time and the movement of objects therein. A more recent reaction against this view sought to explain this capacity solely in terms of perceptual mechanisms of object individuation. Neither explanation remains fully satisfactory. This book argues for a more desirable middle ground in terms of a pragmatist approach to demonstrative thought, (...) where this capacity is explained through graded practical knowledge of objects. This view allows us to do justice to important insights put forward by both positions criticized in the book, while avoiding their potential shortcomings. It also paves the way to a more pragmatist approach to the theory of mental representation, where the notion of practical knowledge is allowed to play a central role in our cognitive life. Finally, it shows how practical knowledge may be firmly rooted in neurobiological processes and mechanisms that conform to what the empirical sciences tell us about the mind. (shrink)

Cognitive Science combines the interdisciplinary streams of cognitive science into a unified narrative in an all-encompassing introduction to the field. This text presents cognitive science as a discipline in its own right, and teaches students to apply the techniques and theories of the cognitive scientist's 'toolkit' - the vast range of methods and tools that cognitive scientists use to study the mind. Thematically organized, rather than by separate disciplines, Cognitive Science underscores the problems and solutions of (...) cognitive science, rather than those of the subjects that contribute to it - psychology, neuroscience, linguistics, etc. The generous use of examples, illustrations, and applications demonstrates how theory is applied to unlock the mysteries of the human mind. Drawing upon cutting-edge research, the text has been updated and enhanced to incorporate new studies and key experiments since the first edition. A new chapter on consciousness has also been added.

After introducing semantic anti-realism and the paradox of knowability, the paper offers a reconstruction of the anti-realist argument from understanding. The proposed reconstruction validates an unrestricted principle to the effect that truth requires the existence of a certain kind of “demonstration”. The paper shows that that principle fails to imply the problematic instances of the original unrestricted feasible-knowability principle but that the overall view underlying the new principle still has unrestricted epistemic consequences. Appealing precisely to the paradox of knowability, the (...) paper also argues, against the BHK semantics, for the non- constructive character of the demonstrations envisaged by semantic anti-realism, and contends that, in such setting, one of the most natural arguments for a broadly intuitionist revision of classical logic loses all its force.Tras presentar el anti-realismo semántico y la paradoja de la cognoscibilidad, el artículo ofrece una reconstrucción del argumento anti-realista basado en la comprensión. La reconstrucción que se propone valida un principio irrestricto, del que se sigue que la verdad requiere la existencia de un determinado tipo de “demostración”. El artículo muestra que este principio no implica las instancias problemáticas del original principio irrestricto de la cognoscibilidad realizable, y que la concepción general que subyace al nuevo principio todavía tiene consecuencias epistémicas irrestrictas. Apelando precisamente a la paradoja de la cognoscibilidad, el artículo argumenta además, en contra de la semántica BHK, a favor del carácter no constructivo de las demostraciones que contempla el anti-realismo semántico, y defiende que, en ese marco, uno de los argumentos más naturales a favor de una revisión a grandes rasgos intuicionista de la lógica clásica pierde toda su fuerza.

This article presents Aristotelian scientific demonstration as a method for attaining intuitive theoria of essential natures. Such insight is attained through the discursive demonstrative syllogism. Science is understood as knowledge of causes through their effects, as opposed to an operative knowledge of the consequences of causes. This understanding is thus counter-reductionist.

ArgumentThe British Astronomer Royal, Nevil Maskelyne, spent four months on a Scottish mountainside in 1774, making observations of zenith stars and coordinating a detailed survey of the size and shape of the mountain Schiehallion, in order to demonstrate and quantify what was known as “the attraction of mountains.” His endeavors were celebrated in London, where it was stated that he had given proof of the universality of Newtonian gravitation and allowed for a calculation of the relative densities of the earth (...) as a whole and the earth near its surface. This paper argues that the “Schiehallion Experiment” was as much a trial of the precision of Maskelyne's instruments and their expert management as it was a trial of Newtonian theory. By tracing the biography of the key instrument used by Maskelyne, his zenith sector, we see how much personal credibility was a stake for him in Scotland. By considering the mountainside as a place to test and reveal the precision of astronomical instruments we see a link between the Scottish endeavors and Maskelyne's ambitions for the Greenwich Observatory.
