John Paul II’s Faith and Reason was written against a background of Catholic scholarship focusing notably on the New Testament, St. Augustine’s Confessions, St. Thomas’s De Veritate, and the encyclicals of various pre-Vatican II popes. A detailed, textually based critique of these early sources reveals inconsistencies and conceptual errors that are shown to carry over into Faith and Reason. John Paul II’s treatment of reason, in particular, turns out to be aberrant to the point of incoherence. It is inconceivable how (...) this reason could join with faith in a way that lifts the human spirit to a contemplation of truth, as stated in the Preface of the encyclical. There is another sense of reason, however, which demonstrably is capable of cooperating with faith to achieve this effect. This reason is free from the fetters of Neo-Scholasticism that keep John Paul II’s reason grounded. The present study joins forces with the encyclical with a detailed example of this other sense of reason in action. In this example, new truths come to light regarding the complex relation between the first and the second great commandments. (shrink)

A narrative history of Notre Dame's world renowned philosophy department, which divides the nearly 80 decades into three distinct periods: textbook Thomism, pluralism, and professionalism.

This book, published in 1976, presents an entirely original approach to the subject of the mind-body problem, examining it in terms of the conceptual links between the physical sciences and the sciences of human behaviour. It is based on the cybernetic concepts of information and feedback and on the related concepts of thermodynamic and communication-theoretic entropy. The foundation of the approach is the theme of continuity between evolution, learning and human consciousness. The author defines life as a process of energy (...) exchange between organism and environment, and evolution as a feedback process maintaining equilibrium between environment and reproductive group. He demonstrates that closely related feedback processes on the levels of the behaving organism and of the organism’s nervous system constitute the phenomena of learning and consciousness respectively. He analyses language as an expedient for extending human information-processing and control capacities beyond those provided by one’s own nervous system, and shows reason to be a mode of processing information in the form of concepts removed from immediate stimulus control. The last chapter touches on colour vision, pleasure and pain, intentionality, self-awareness and other subjective phenomena. Of special interest to the communication theorist and philosopher, this study is also of interest to psychologists and anyone interested in the connection between the physical and life sciences.

This article responds to two unresolved and crucial problems of cognitive science: (1) What is actually accomplished by functions of the nervous system that we ordinarily describe in the intentional idiom? and (2) What makes the information processing involved in these functions semantic? It is argued that, contrary to the assumptions of many cognitive theorists, the computational approach does not provide coherent answers to these problems, and that a more promising start would be to fall back on mathematical communication theory (...) and, with the help of evolutionary biology and neurophysiology, to attempt a characterization of the adaptive processes involved in visual perception. Visual representations are explained as patterns of cortical activity that are enabled to focus on objects in the changing visual environment by constantly adjusting to maintain levels of mutual information between pattern and object that are adequate for continuing perceptual control. In these terms, the answer proposed to (1) is that the intentional functions of vision are those involved in the establishment and maintenance of such representations, and to (2) that semantic features are added to the information processes of vision with the focus on objects that these representations accomplish. The article concludes with proposals for extending this account of intentionality to the higher domains of conceptualization and reason, and with speculation about how semantic information-processing might be achieved in mechanical systems.

In lieu of an abstract, here is a brief excerpt of the content:Of Dialogues and SeedsKenneth SeeskinPlato’s Literary Garden: How to Read a Platonic Dialogue, by Kenneth M. Sayre; xxiii & 292 pp. Notre Dame: University of Notre Dame Press, 1995, $34.95.One of the best known paradoxes in the Platonic corpus occurs in the Seventh Letter (341), when Plato says that he has never written about the problems which concern him and never will. His reason: “This knowledge can (...) never be put into words like other subjects; but is generated by living with the matter itself and from many conversations (ek polle\s sunousias). Then like a flashing light when a fire is kindled, it is born in the soul and nourishes itself.” Why would the most gifted philosophical writer in history say that when it comes to goodness, beauty, or justice, language is an inadequate medium in which to convey truth?One answer is that Plato had an esoteric doctrine that he divulged to a few close associates but did not express in the dialogues. 1 The crux of the esotericist position is that Plato’s objection is not to language as such but to written language in particular. A more satisfying answer is offered by Kenneth M. Sayre in this recent book. According to Sayre, Plato wrote dialogues to allow the reader to have conversation (sunousia) with the author “in an indirect manner” and to facilitate the reader’s own discovery of truth. In other words, the dialogues are surrogates for the sort of discussions Plato shared with Socrates “in hopes of producing a similar effect in the mind of the reader.” [End Page 167]If Sayre is right, the problem discussed in the Seventh Letter is not limited to written communication but involves “logoi in whatever form we might identify them today” (p. 159). Sayre enlarges on this insight by claiming (p. 18) that for Plato “philosophic knowledge is not awareness of the truth of propositions” but “discernment of some aspect of reality.” 2 Nor is this view limited to the Seventh Letter; Sayre finds it expressed in dialogues ranging from the Meno to the Statesman. Although I have problems with some of the details of this interpretation, it is noteworthy that the Seventh Letter (342a) does claim its epistemology is not new and “has been expounded many times before.” 3The title of Sayre’s book is taken from a famous passage in the Phaedrus (276), where Socrates says that while written language gives the appearance of finality and inviolability, it is an image (eido\lon) of living speech, by which he means words that can defend themselves and are accompanied by knowledge. But as Sayre points out, the passage also carves out a role for written speech by claiming that it is legitimate for the dialectician to plant seeds in “a literary garden” to assist memory in later years and to help others who “wish to walk in the same path.” In fact, the passage tells us that the dialectician will select a soul of the right type and take pleasure in watching the seeds grow and mature. In keeping with Plato’s metaphor, Sayre organizes his chapters into functions associated with gardening: some dialogues prepare the ground, others sow the seeds, train the shoots, or allow us to reap the fruit. The book ends with an appendix on how to read a specific dialogue, the Theaetetus, in a way that emphasizes indirect or imagined conversation. As one might expect, Sayre takes the Theaetetus to imply that knowledge cannot be defined as true belief with a logos.Although not a highly technical work, Plato’s Literary Garden is a thoughtful and thought-provoking one designed for someone who wants students to see that Plato is not just another philosopher with another doctrine to peddle. So the first step in reading a Platonic dialogue is to recognize with Sayre that the dialogues are not “proto-essays” and that the decision to write dialogues is tied up with important features of Plato’s epistemology. But does that mean, as Sayre claims (p. 12), that “Plato’s dialogues were not conceived by their author as contexts in which to develop and to display positive arguments for... (shrink)

At the beginning of his Metaphysics, Aristotle attributed several strange-sounding theses to Plato. Generations of Plato scholars have assumed that these could not be found in the dialogues. In heated arguments, they have debated the significance of these claims, some arguing that they constituted an 'unwritten teaching' and others maintaining that Aristotle was mistaken in attributing them to Plato. In a prior book-length study on Plato's late ontology, Kenneth M. Sayre demonstrated that, despite differences in terminology, these claims (...) correspond to themes developed by Plato in the Parmenides and the Philebus. In this book, he shows how this correspondence can be extended to key, but previously obscure, passages in the Statesman. He also examines the interpretative consequences for other sections of that dialogue, particularly those concerned with the practice of dialectical inquiry. (shrink)

Applying the analytical methods of modern logic to problems of interpretation in Plato, the author traces the development of Plato's analytic method from the crude form expressed in the Phaedo to the considerably more sophisticated and powerful techniques practiced in the later methodological dialogues.

A new edition of a classic work compares Plato's dialogues to Aristotle's depiction of them. Reprint.

Parmenides is generally recognized as Plato's most difficult dialogue. This work argues that the key to unlocking the puzzles of Parmenides II lies in the proper interpretive pairing of the eight hypotheses under which its arguments are grouped.

Contesting much contemporary epistemology and cognitive science, noted philosopher Kenneth M. Sayre argues that, while some cognitive attitudes such as believing take propositions as objects, there are many others whose objects are instead states of affairs.

A model of causation is presented which shares the advantages of Reichenbach's definition in terms of the screening-off relation, but which has the added advantage of distinguishing cause and effect without reference to temporal directionality. This model is defined in terms of the masking relation, which in turn is defined in terms of the equivocation relation of communication theory.

The problem of semantic content is the problem of explicating those features of brain processes by virtue of which they may properly be thought to possess meaning or reference. This paper criticizes the account of semantic content associated with fodor's version of cognitive science, And offers an alternative account based on mathematical communication theory. Its key concept is that of a neuronal representation maintaining a high-Level of mutual information with a designated external state of affairs under changing conditions of perceptual (...) presentation.

In __Unearthed: The Economic Roots of Our Environmental Crisis_, _Kenneth M. Sayre argues that the only way to resolve our current environmental crisis is to reduce our energy consumption to a level where the entropy produced by that consumption no longer exceeds the biosphere’s ability to dispose of it. Tangible illustrations of this entropy buildup include global warming, ozone depletion, loss of species diversity, and unmanageable amounts of nonbiodegradable waste._ Degradation of the biosphere is tied directly to human energy (...) use, which has been increasing exponentially since the Industrial Revolution. Energy use, in turn, is directly correlated with economic production. Sayre shows how these three factors are invariably bound together. The unavoidable conclusion is that the only way to resolve our environmental crisis is to reverse the present pattern of growth in the world economy. Economic growth is motivated by social values. Key among them are the desire for wealth and consumer values including gratification, convenience, and acquisition of goods. Sayre maintains that economic growth can be reversed only by eliminating these social values in favor of others more conducive to environmental health. Eliminating these values will involve major changes in lifestyle within industrial societies generally. Only with such changes in lifestyle, he argues, does human society as we know it have a chance of survival. Clearly written and thoroughly documented, this book provides a comprehensive overview of our complex environmental predicament. "With unerring logic and science, Kenneth Sayre dissects the origins of the ecological crisis and points to the necessary recalibration of industrial societies with the laws of thermodynamics and ecology. It is a radical book in that he gets to the heart of what ails us, and it charts a course toward a future grounded in authentic hope." — David W. Orr, Oberlin College__ “Sayre’s assessment forces all seeking a sustainable future to reexamine the preeminence accorded to clean energy. _ Unearthed __uniquely combines thermodynamics and ethics to challenge and broaden readers’ understandings of the systemic issues we face. Assembled and presented with piercing clarity, __Unearthed __constructs a brilliant framework for making sense of our quiet, but growing crises.” —_Felipe Witchger, IHS Cambridge Energy Research Associates__ “Kenneth M. Sayre’s _ Unearthed: The Economic Roots of Our Environmental Crisis__ constitutes a major and significant contribution to our understanding of the grave ecological crisis facing humanity. It covers the complete picture, from the basic physical causes of the destruction of our environment to the sociological or anthropological forces that condition our self-destructive actions. The work not only is a brilliant and mind-sweeping piece of diagnosis and prognosis, but it goes all the way to point towards possible solutions.” —_Fernando del Río Haza, Laboratorio de Termodinámica, Universidad Autónoma Metropolitana, Iztapalapa, Mexico_.

This book will please different people for different reasons. Those who have felt the lack of an adequate analysis of the emotions will be gratified by the author’s clarity and comprehension of view in distinguishing among feelings, desires, and pleasures. Ethical theorists may benefit from his analysis of the difference between motives and intentions. Philosophers who have been puzzled by Wittgenstein’s remarks on sensation in Parts I and II of Philosophical Investigations may expect to find some relief in the author’s (...) straightforward discussion of feelings under Wittgenstein’s inspiration. And philosophers who, for whatever reason, have regretted the lack of communication between the Scholastic tradition and the tradition of Modern Empiricism will be heartened by the lively way in which insights of St Thomas Aquinas and of Aristotle himself are brought to bear in relevant terms upon problems of human action and emotion inherited from Descartes and Hume. The author is partisan in this book. He sides generally with Aristotle, Aquinas, Wittgenstein, Anscombe and Geach, and generally against Descartes, Hume, Russell, Ryle and various contemporary logicians. But the price of this alignment does not include befuddlement about what his antagonists have to say, nor blindness to some of the virtues of their positions. In this respect alone, if not only in this respect, the author’s discussion is both refreshing and worthy of a student with teachers such as his. (shrink)

I do not wish at this time to dispute either or. I do not believe, however, that the intermediate step can be adequately justified, and hence remain unconvinced by the purported conclusion. The most recent presentation of this argument is in Professor Dreyfus' article "Why Computers must have Bodies in order to be Intelligent," a discussion of which will serve to explain my lack of confidence in any argument of this general form.

Gödel's theorem seems to me to prove that Mechanism is false, that is, that minds cannot be explained as machines. So also has it seemed to many other people: almost every mathematical logician I have put the matter to has confessed to similar thoughts, but has felt reluctant to commit himself definitely until he could see the whole argument set out, with all objections fully stated and properly met.1 This I attempt to do.

We attempt to clarify the nature of philosophic assertions about perception by considering how one can argue effectively against such assertions. Reasons are given, with illustrative assertions from Aristotle and Berkeley, why one cannot argue effectively against such either (1) by arguing for contrary assertions in competing theories or (2) by appealing to scientific observation. Effective arguments against such accounts include (1) those which demonstrate inconsistency within the account, (2) those which disclose an unintelligibility within the account, and (3) those (...) which show the account is inadequate in scope. These are illustrated respectively by arguments (i) against Phenomenalism, (ii) against Aristotle's account of the identity in act of sensing faculty and sensed object, and (iii) against Berkeley's account of observation through instruments.

Psychologists, physiologists, and philosophers find different problems in perception, and the interested layman is often puzzled when he comes to realize how little scientific and philosophic theories of perception have in common. The approach of this book is synoptic, in that the author believes that evidence from scientific theories of perception can be brought to bear upon the solution of problems traditionally left to the philosopher. Among problems which Hirst attempts to unravel with the help of physiology and psychology are (...) those regarding the physical causation of mental events, the status of primary and secondary qualities, and the publicity of perceptual objects.
