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.

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.

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.

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.

Having noted my intention to improve upon other statistical analyses of causal relatedness by providing theoretical means to distinguish cause and effect without reference to temporality [1], Professor Shrader argues [3] that the alternative model I offer falters “before the same sort of examples he had previously used to assail” these other analyses. Although the assailant seems both to have misunderstood the model in question and to have overestimated the effect of his counterexamples, his objections provide a welcome opportunity for (...) clarification.

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)

Environmental ethics continues to be dominated by an in/erential view of ethical theory, according to which moral prescriptions and proscriptions are deduced from general principles, which in turn are arrived at intuitively or by some form of induction. I argue that the inferential approach contributes litde to the pressing need which environmental philosophers have been attempting to address in recent decades-the need for a set of normative values actually in place within industrial society that will help preserve the environment from (...) human destruction. I propose an alternative view according to which the aim of environmental ethics is (1) a clear understanding of how moral norms actually come to be instituted in a given society, (2) the analysis of the practical effect of such norms from an environmental perspective, and (3) an examination of the relative desirability of alternative norms in light of their environmental effects. In pursuing this aim, environmental ethics should join forces with anthropology, economics, and other areas of social science in hopes of generatirtg a basis for empirical information about how moral norms actually operate. Such information might help persuade society at large of the importance of being guided by an environmentally sound set of normative values. (shrink)

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)

Plato’s method of hypothesis is initiated in the Meno, is featured in the Phaedo and the Republic, and is further developed in the Theaetetus. His method of collection and division is mentioned in the Republic, is featured in the Phaedrus,and is elaborated with modifications in the Sophist and the Statesman. Both methods aim at definitions in terms of necessary and sufficient conditions. In the course of these developments, the former method is shown to be weak in its treatment of sufficient (...) conditions, and the latter is shown to be comparably weak in its treatment of necessary conditions. A third method, which avoids these difficulties, is introduced in the first part of the Parmenides and is applied in connection with the eight hypotheses that follow. This application yields a demonstration of serious shortcomings both in historical Eleaticism and in the Eleatically-inspired theory of Forms in the Phaedo and the Republic, along with a demonstration of comparative strengths in historical Pythagoreanism and in the Pythagorean- inspiried theory of Forms in the Statesman and the Philebus.

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.

Our erises of energy and of social values are eausally interrelated. Our energy problems have contributed substantially to our contemporary value problems, as evident, for example, by the institution of the private automobile, whieh has begun to erode the very values it initially served. That our energy erisis has resulted from problems of value is illustrated by setting up a simple model of producer-consumerinteraetion, with egoism and hedonism as dominant prineiples of duty and of good respeetively, and by showing that (...) an energy crisis like the one we are currently experieneing is practically inevitable. These discussions lead to an assessment of the possible roles moral philosophy might play in confronting these two crises. (shrink)
