This is a translation of II Motore Immobile (Metafisica, libro XII), Traduzione intégrale, introduzione e commento by Giovanni Reale (Editrice La Scuola, Brescia, 4th Ed. 1971)- The author offers a unitary reading of the famous twelfth book of Aristotle's Metaphysics. The book is intended for students who wish to read the text itself of Aristotle’s, so that the introduction and commentary to the text and the summaries of the entire Metaphysics as well as the twelfth book gives the student ample (...) material to read the text intelligently. The work is aware of the current state of Aristotelian studies but does not intrude them into the commentary, because they should be reserved for more specialized work which the author has completed.

“Great philosophers as well as great artists have the gift of inspiring profoundly different conceptions and meaning in the individuals who contemplate their work,” writes Joseph Owens. Even now, twenty-three centuries after the philosopher’s death, the study of Aristotle continues to challenge us and to broaden our intellectual outlook. In this volume, John R. Catan has gathered together 18 major essays by the well-known aristotelian scholar Joseph Owens that have influenced current opinion on the philosopher. The collection represents (...) the first well-rounded picture of Owens’s interpretation of the theory of knowledge and associated cognitive problems in moral philosophy. Among the themes highlighted are: universality, cognition, matter and predication, the sciences, the soul, and nature. Included is a complete Owens bibliography, covering the years from 1946 to the present. (shrink)

Beginning with the origins of Western philosophy, the profound creation of the Hellenic genius, Reale presents an appreciation of the Naturalists, the Sophists, Socrates, and the Minor Socratics. Special attention is paid to the Eleatics because their problems decisively mark Platonic and Aristotelian philosophy. Interpretation of the Sophists benefits from the recent reevaluation of their thought. Socrates himself would be inconceivable without the Sophists since he is one of them. Socrates is given major prominence. Plato, Aristotle, and all of Hellenistic (...) philosophy are deeply impregnated with his words and spirit. The teachings of the Minor Socratics are interpreted as one-sided reductions of the pluralistic values of Socratic thought and as anticipations of some issues that explode later in the Hellenistic Age. There are two appendices. The first concerns Orphism and contains a series of documents indispensable for the comprehension of some aspects of pre-Socratic and Platonic thought. The second explains the key to understanding the message of the Greeks—the message of “theorein”. (shrink)

This book covers the first 500 years of the common era. These years witnessed the revivals of Aristotelianism, Epicureanism, Pyrrhonism, Cynicism, and Pythagoreanism; but by far the most important movement was the revival of Platonism under Plotinus. Here, the historical context of Plotinus is provided including the currents of thought that preceded him and opened the path for him. The presuppositions of the Enneads are made explicit and the thought of Plotinus is reconstructed. The author reorients the expositions of Middle (...) Platonism and neo-Pythagoreanism. He provides a full exposition of Hermeticism and the doctrines of the Chaldean Oracles. He also defends the notion that Philo of Alexandria nourished a Jewish philosophy, not an eclectic mixture.

Reale’s volume supplies a synthesis previously lacking—a synthesis in the historical treatment of the great philosophies of the Hellenistic Age: the Academy, the Peripatos, the Stoa, the Garden of Epicurus, Scepticism, and Eclecticism. Reale’s extensive and fully documented treatment of the major schools of the period is unified by his thesis that the ethics developed by these major schools were secular faiths that sprang from intuitions about the meaning of life first emotionally grasped and then systematically and rationally developed. It (...) is for this reason that the teachings of these schools endured almost continuously for about 500 years. It is for the same reason that the founders of the schools were considered gods and were actually, in a certain sense, the saints of secular faiths and religions. In this book, Reale traces the decline of the philosophical schools of the classical period, the post-Platonic Academy, the post-Aristotelian Peripatos, and the minor socratic schools. The destruction of the polis and the incapacity of the schools to address the concerns of the new age were the fertile grounds from which the new schools developed. The Garden of Epicurus, the Porch of Zeno, and the sceptical movement initiated by Pyrrho form the core of the volume. The volume contains a select bibliography and an index of names and Greek terms, as well as an index of citations. (shrink)

In this book Reale presents Plato and Aristotle. At the center of Reale’s interpretation of Plato is the fulcrum of the supersensible, the metaphysical discovery that Plato presented as a result of the Second Voyage. This discovery of the supersensible is, in Reale’s view, not only the fundamental phase of ancient thought, but it also constitutes a milestone on the path of western philosophy. Reale presents Plato in three different dimensions: the theoretic, the mystical-religious, and the political. Each of these (...) components takes on meaning from the Second Voyage. In addition, Reale has shown that only in the light of the Unwritten Doctrines handed down through the indirect tradition, do these three components, and the Second Voyage itself, acquire their full meaning, and only in this way is a unitary conception of Plato’s thought achieved. The interpretation of Aristotle that Reale proposes depends on his interpretation of Plato. Aristotle read without preconceptions is not the antithesis of Plato. Reale points out that Aristotle was unique among thinkers close to Plato, in being the one who developed, at least in part, his Second Voyage. The systematic-unitary interpretation of Aristotle which Reale has previously supported converges with the new systematic-unitary interpretation of Plato. Certain doctrinal positions which are usually reserved to treatments in monographs will be explored, because only in this way can the two distinctive traits of Aristotle’s thought emerge: the way in which he tries to overcome and confirm the Socratic-Platonic positions, and the way in which he formally creates the system of philosophical knowledge.

This is a book about the relationship of the two traditions of Platonic interpretation -- the indirect and the direct traditions, the written dialogues and the unwritten doctrines. Kramer, who is the foremost proponent of the Tubingen School of interpretation, presents the unwritten doctrines as the crown of Plato's system and the key revealing it. Kramer unfolds the philosophical significance of the unwritten doctrines in their fullness. He demonstrates the hermeneutic fruitfulness of the unwritten doctrines when applied to the dialogues. (...) He shows that the doctrines are a revival of the presocratic theory renovated and brought to a new plane through Socrates. In this way, Plato emerges as the creator of classical metaphysics. In the Third Part, Kramer compares the structure of Platonism, as construed by the Tubingen School, with current philosophical structures such as analytic philosophy, Hegel, phenomenology, and Heidegger. Of the five appendices, the most important presents English translations of the ancient testimonies on the unwritten doctrines. These include the "self-testimonies of Plato." There is also a bibliography on the problem of the unwritten doctrines. (shrink)

Reale’s monumental work establishes the exact dimensions of Aristotle’s concept of first philosophy and proves the profound unity of concept that exists in Aristotle’s Metaphysics. Reale’s opposition to the genetic interpretation of the Metaphysics is an updated return to a more traditional view of Aristotle’s work, one which runs counter to nearly all contemporary scholarship. Reale argues that Aristotle’s first philosophy includes a study of being, a study of substance, a study of divine substance, and a study of principles and (...) causes, all of which are integrated and dialectically reconciled.

These volumes are the much augmented and heavily revised commentary and text by Giovanni Reale of Aristotle's Metaphysics, which was originally issued in two volumes in the series Collana di Filosofi Antichi from the Centro di Studi Filosofici di Gallarate, published by Luigi Loffredo Editore, Naples. The volumes are part of the collection entitled "Temi metafisici e problemi del pensiero antico. Studi e testi," published by the Centro di Ricerche di Metafisica of the Catholic University of the Sacred Heart, Milan. (...) The two volume set was published in 1968 and much has transpired since, including the publication of Reale's major work, A History of Ancient Philosophy, in five volumes, of which four volumes have been translated into English. The second volume of the series, Plato and Aristotle, was the vehicle of a profound change in Reale's views on Plato and subsequently on Aristotle. Reale came to the attention of the Anglophone world through his work The Concept of First Philosophy and the Unity of the Metaphysics, which elegantly undermined the Jaegerian thesis on the development of Aristotle's metaphysical thought by showing that the four dimensions, or strands, of Aristotle's thought on metaphysics, although conceptually distinct, interpenetrated one another in a fruitful manner which gave length, breadth, and depth to his treatment of metaphysics, or first philosophy.

John Searle's Speech Acts (1969) and Expression and Meaning (1979) developed a highly original and influential approach to the study of language. But behind both works lay the assumption that the philosophy of language is in the end a branch of the philosophy of the mind: speech acts are forms of human action and represent just one example of the mind's capacity to relate the human organism to the world. The present book is concerned with these biologically fundamental capacities, (...) and, though third in the sequence, in effect it provides the philosophical foundations for the other two. Intentionality is taken to be the crucial mental phenomenon, and its analysis involves wide-ranging discussions of perception, action, causation, meaning, and reference. In all these areas John Searle has original and stimulating views. He ends with a resolution of the 'mind-body' problem. (shrink)

Techniques for achieving moral enhancement will modify brain processes to produce what is alleged to be more moral conduct. Neurophilosophy and neuroethics must ponder what “moral enhancement” could possibly be, if possible at all. Objections to the very possibility of moral enhancement, raised from various philosophical and neuroscientific standpoints, fail to justify skepticism, but they do place serious constraints on the kinds of efficacious moral enhancers. While there won't be a “morality pill,” and hopes for global moral enlightenment will remain (...) hopes, there will be a large variety of behavioral modifiers described as enhancers of some aspect of morality or another according to prevailing social norms. The most likely moral enhancers that will be designed, tested, and marketed in the near future will attempt to alleviate seriously immoral and illegal behavior. Some enhancers diminishing antisocial conduct and a few designed to elevate moral conduct above normal levels will also become available, although their widespread use is doubtful. There will also be specialized modifications for enhancing whatever an individual personally regards as moral, and for enabling better performance by a person in an operational role. A measure of skepticism toward all the proposed kinds of moral enhancement is advised, and where political implementation of moral enhancers is concerned, a healthy amount of cynicism as well.

This article investigates the potential of fMRI to test assumptions about different components in models of complex cognitive tasks. If the components of a model can be associated with specific brain regions, one can make predictions for the temporal course of the BOLD response in these regions. An event‐locked procedure is described for dealing with temporal variability and bringing model runs and individual data trials into alignment. Statistical methods for testing the model are described that deal with the scan‐to‐scan correlations (...) in the errors of measurement of the BOLD signal. This approach is illustrated using a “sacrificial” ACT‐R model that involves mapping 6 modules onto 6 brain regions in an experiment from Ravizza, Anderson, and Carter (in press) concerned with equation solving. The model's visual encoding predicted the BOLD response in the fusiform gyrus, its controlled retrieval predicted the BOLD response in the lateral inferior prefrontal cortex, and its subgoal setting predicted the BOLD response in the anterior cingulate cortex. On the other hand, its motor programming failed to predict anticipatory activation in the motor cortex, its representational changes failed to predicted the pattern of activity in the posterior parietal cortex, and its procedural component failed to predict an initial spike in caudate. The results illustrate the power of such data to direct the development of a theory of complex problem solving, both at the level of a specific task model as well as at the level of the cognitive architecture.

ABSTRACT:Intermediaries, such as accountants, lawyers, and bankers, are gatekeepers, which are parties whose cooperation is necessary for corporations to function and who, by withholding cooperation, are able to prevent significant corporate misconduct. The recent scandals at Enron and other corporations were due, in part, to failures by gatekeeper institutions. However, intermediaries exist primarily to provide for-fee services and not specifically to detect and deter misconduct. Insofar as these institutions are gatekeepers or guardians, they serve reluctantly. Hence the question: What is (...) the responsibility of intermediaries to act as gatekeepers? This article argues that the appropriate moral, as well as legal, principle for justifying responsibility in a gatekeeper role is cost effectiveness. This conclusion is reached by means of a hypothetical exercise called the investors’ bargain in which investors—who bear the costs and receive the benefits of intermediaries’ gatekeeper role—are asked to choose the best means of protecting their interests.

John R. Schneider explores the problem that animal suffering, caused by the inherent nature of Darwinian evolution, poses to belief in theism. Examining the aesthetic aspects of this moral problem, Schneider focuses on the three prevailing approaches to it: that the Fall caused animal suffering in nature (Lapsarian Theodicy), that Darwinian evolution was the only way for God to create an acceptably good and valuable world (Only-Way Theodicy), and that evolution is the source of major, God-justifying beauty (Aesthetic Theodicy). (...) He also uses canonical texts and doctrines from Judaism and Christianity - notably the book of Job, and the doctrines of the incarnation, atonement, and resurrection - to build on insights taken from the non-lapsarian alternative approaches. Schneider thus constructs an original, God-justifying account of God and the evolutionary suffering of animals. His book enables readers to see that the Darwinian configuration of animal suffering unveiled by scientists is not as implausible on Christian theism as commonly supposed. (shrink)

Anne Conway rejects the view that creatures are essentially members of any natural kind more specific than the kind 'creature'. That is, she rejects essentialism about species membership. This chapter provides an analysis of one of Anne Conway's arguments against such essentialism, which (as I argue) is drawn from metaethical rather than metaphysical premises. In her view, if a creature's species or kind were inscribed in its essence, that essence would constitute a limit on the creature's potential to participate in (...) the divine good. It is this consideration that ultimately leads her to reject essentialism about species membership. The chapter concludes with an examination of some of the metaethical consequences of Conway's view as well as a lesson it can teach us about ideal adviser accounts of the good. (shrink)

The human cognitive architecture consists of a set of largely independent modules associated with different brain regions. This book discusses in detail how these various modules can combine to produce behaviours as varied as driving a car and solving an algebraic equation.

In this collection of essays, written especially for this volume, many of the most prominent scholars on Dewey are inspired to search for that new enlightenment that Dewey himself sought, reconfigured to deal with the pressing problems of our times.

Can the output of human cognition be predicted from the assumption that it is an optimal response to the information-processing demands of the environment? A methodology called rational analysis is described for deriving predictions about cognitive phenomena using optimization assumptions. The predictions flow from the statistical structure of the environment and not the assumed structure of the mind. Bayesian inference is used, assuming that people start with a weak prior model of the world which they integrate with experience to develop (...) stronger models of specific aspects of the world. Cognitive performance maximizes the difference between the expected gain and cost of mental effort. Memory performance can be predicted on the assumption that retrieval seeks a maximal trade-off between the probability of finding the relevant memories and the effort required to do so; in categorization performance there is a similar trade-off between accuracy in predicting object features and the cost of hypothesis formation; in casual inference the trade-off is between accuracy in predicting future events and the cost of hypothesis formation; and in problem solving it is between the probability of achieving goals and the cost of both external and mental problem-solving search. The implemention of these rational prescriptions in neurally plausible architecture is also discussed. (shrink)

Naturalism is widely regarded as the dominant philosophical worldview in the West. The prestige of science and the power of technology have driven naturalism to prominence, even as deep questions mount on all sides. In this volume of all new essays, prominent philosophers consider a wide variety of challenges to naturalism, proposing improved defenses and novel developments in this influential worldview. Some essays question whether naturalism is a unified philosophy, and try to determine how one or another variety of naturalism (...) has an advantage. Other essays defend naturalism's approaches to religion, the mind, experience, morality, and society. To ensure that naturalism has a strong future, this volume's authors are determined to help reformulate its principles for the 21st century. Among the contributors are Mario Bunge, Paul Kurtz, John Lachs, Isaac Levi, Joseph Margolis, Nicholas Rescher, John R. Shook, and other leading philosophers. (shrink)

In informal terms, abductive reasoning involves inferring the best or most plausible explanation from a given set of facts or data. It is a common occurrence in everyday life and crops up in such diverse places as medical diagnosis, scientific theory formation, accident investigation, language understanding, and jury deliberation. In recent years, it has become a popular and fruitful topic in artificial intelligence research. This volume breaks new ground in the scientific, philosophical, and technological study of abduction. It presents new (...) ideas about inferential and information-processing foundations for knowledge and certainty. The authors argue that knowledge arises from experience by processes of abductive inference, in contrast to the view that it arises non-inferentially, or that deduction and inductive generalization are enough to account for knowledge. Much AI research is hypothetical, so the importance of this book is that it reports key discoveries about abduction that have been made as a result of designing, building, testing, and analyzing actual working knowledge-based systems for medical diagnosis and other abductive tasks. The book tells the story of six generations of increasingly sophisticated generic abduction machines, RED-1, RED-2, PEIRCE, MDX2, TIPS, QUAWDS, and the discovery of reasoning strategies that make it computationally feasible to form well-justified composite explanatory hypotheses, despite the threat of combinatorial explosion. The final chapter argues that perception is logically abductive and presents a layered-abduction computational model of perceptual information processing. This book will be of great interest to researchers in AI, cognitive science, and philosophy of science. (shrink)

The title of The Rediscovery of the Mind suggests the question "When was the mind lost?" Since most people may not be aware that it ever was lost, we must also then ask "Who lost it?" It was lost, of course, only by philosophers, by certain philosophers. This passed unnoticed by society at large. The "rediscovery" is also likely to pass unnoticed. But has the mind been rediscovered by the same philosophers who "lost" it? Probably not. John Searle is (...) an analytic philosopher, with some of the same notions as the positivists and behaviorists who rejected consciousness and "lost" the mind in the first place, but he also does not sound like the kind of reductionist who would have joined that crowd. His views, indeed, are sensible enough, and some of his insights so important, that it is a shame to find his thought profoundly limited by some of the same mistakes and prejudices that ruined philosophy, and not just philosophy of mind, under the influence of those positivists and behaviorists. There is enough of genuine value in his treatment, that it can easily be taken up and, with relatively slight modification, added to what is of permanent value in the history of philosophy. (shrink)

In The Construction of Social Reality, John Searle argues that there are two kinds of facts--some that are independent of human observers, and some that require..

The renowned philosopher John Searle reveals the fundamental nature of social reality. What kinds of things are money, property, governments, nations, marriages, cocktail parties, and football games? Searle explains the key role played by language in the creation, constitution, and maintenance of social reality. We make statements about social facts that are completely objective, for example: Barack Obama is President of the United States, the piece of paper in my hand is a twenty-dollar bill, I got married in London, (...) etc. And yet these facts only exist because we think they exist. How is it possible that we can have factual objective knowledge of a reality that is created by subjective opinions? This is part of a much larger question: How can we give an account of ourselves, with our peculiar human traits DS mind, reason, freedom, society - in a world that we know independently consists of mindless, meaningless particles? How can we account for our social and mental existence in a realm of brute physical facts? In answering this question, Searle avoids postulating different realms of being, a mental and a physical, or worse yet, a mental, a physical, and a social. There is just one reality: Searle shows how the human reality fits into that one reality. Mind, language, and civilization are natural products of the basic facts of the physical world described by physics, chemistry and biology. Searle explains how language creates and maintains the elaborate structures of human social institutions. These institutions serve to create and distribute power relations that are pervasive and often invisible. These power relations motivate human actions in a way that provides the glue that holds human civilization together. Searle shows how this account illuminates human rationality, free will, political power, and human rights. Our social world is a world created and maintained by language. (shrink)

The appropriate methodology for psychological research depends on whether one is studying mental algorithms or their implementation. Mental algorithms are abstract specifications of the steps taken by procedures that run in the mind. Implementational issues concern the speed and reliability of these procedures. The algorithmic level can be explored only by studying across-task variation. This contrasts with psychology's dominant methodology of looking for within-task generalities, which is appropriate only for studying implementational issues.The implementation-algorithm distinction is related to a number of (...) other “levels” considered in cognitive science. Its realization in Anderson's ACT theory of cognition is discussed. Research at the algorithmic level is more promising because it is hard to make further fundamental scientific progress at the implementational level with the methodologies available. Protocol data, which are appropriate only for algorithm-level theories, provide a richer source than data at the implementational level. Research at the algorithmic level will also yield more insight into fundamental properties of human knowledge because it is the level at which significant learning transitions are defined.The best way to study the algorithmic level is to look for differential learning outcomes in pedagogical experiments that manipulate instructional experience. This provides control and prediction in realistically complex learning situations. The intelligent tutoring paradigm provides a particularly fruitful way to implement such experiments.The implications of this analysis for the issue of modularity of mind, the status of language, research on human/computer interaction, and connectionist models are also examined.
