§1. The origins of recursion theory. In dedicating a book to Steve Kleene, I referred to him as the person who made recursion theory into a theory. Recursion theory was begun by Kleene's teacher at Princeton, Alonzo Church, who first defined the class of recursive functions; first maintained that this class was the class of computable functions ; and first used this fact to solve negatively some classical problems on the existence of algorithms. However, it was Kleene who, in his (...) thesis and in his subsequent attempts to convince himself of Church's Thesis, developed a general theory of the behavior of the recursive functions. He continued to develop this theory and extend it to new situations throughout his mathematical career. Indeed, all of the research which he did had a close relationship to recursive functions.Church's Thesis arose in an accidental way. In his investigations of a system of logic which he had invented, Church became interested in a class of functions which he called the λ-definable functions. Initially, Church knew that the successor function and the addition function were λ-definable, but not much else. During 1932, Kleene gradually showed1 that this class of functions was quite extensive; and these results became an important part of his thesis 1935a. (shrink)

This is a critical edition of the work published in 1681, two years after Hobbes' death. The dialogue contains mature reflections of Hobbes on the doctrine of sovereignty. It deals with the relation between law and reason, sovereign power, crimes, heresies and punishments. The editor's introduction sets forth arguments for regarding the text as a complete work, contrary to the views of L. Stephen, Tönnies, and Robertson. A critical analysis of the argument in the dialogue is also provided indicating the (...) relation of the dialogue to Hobbes' political philosophy. The dialogue is interesting in portraying the more "liberal" side of Hobbes. It is an invaluable aid to the study of Hobbes.--A. S. C. (shrink)

A clearly written book that purports to analyze "the ends men pursue, and the ways in which these ends are ordered in some kind of system." The driving force behind the analysis is the attempt to present ends, or at least some important ends, as complex entities having a discernible and significant structure, and then to present the priorities, preferences, and relationships that men impose on their ends as themselves constituting a complex, coherent structure, whose principles of ordering may be (...) discerned and criticized. Part one deals with the structure and ordering of ends and reflects the influence of Kant and Rawls. Part two deals with rational ends and social structures, and part three with life and death as values. Of great practical interest are certain concepts such as life plan and budget risk in dealing with the problems of life and death. The book repays careful study.--A. S. C. (shrink)

An able and clear defense of Bradley's principal theses and the underlying conception of metaphysical enterprise. "This is a book about a metaphysician, about metaphysics, and, most importantly, it attempts to develop elements of a metaphysical position long the lines of what is called Absolute Idealism." The Introduction takes up the Verificationists [[sic]] argument and two recent accounts of metaphysics. Part I devotes ten Chapters to the elucidation and defense of Bradley's conception of reality. It culminates in examining three alternative (...) accounts of "Real". Part II considers "the major philosophical theories of the self in order to defend Bradley's Theory of the self within his metaphysical scheme."--A. S. C. (shrink)

Plutarch's essay de fortuna Romanorum has attracted divergent judgements. Ziegler dismissed it as ‘eine nicht weiter ernst zu nehmende rhetorische Stilübung’. By Flacelière it was hailed as ‘une ébauche de méditation sur le prodigieux destin de Rome’. It is time to consider the work afresh and to discover whether there is common ground between these two views. Rather than offering a general appreciation, my treatment will take the work chapter by chapter, considering points of interest as they arise. This method (...) will enable us to compare what Plutarch says on particular subjects and themes in de fort. Rom. with what he says or does not say about them elsewhere. We shall thus be able to see clearly that for the most part the ideas he presents in the essay correspond with his thoughts about the rôle of fortune expressed in more serious writing, and that, where there is no correspondence, this is attributable to the rhetorical background. I do not intend to address directly the frequently discussed but insoluble question of whether we have in de fort. Rom. only one of two original works, that is whether there was once a de virtute Romanorum which Plutarch composed or answered. De fort. Rom. itself in fact gives almost as much prominence to άρετή as to τúχη, and their competing roles will be carefully evaluated. Nor do I look at the dating of the work. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:HUME'S BUNDLES, SELF-CONSCIOUSNESS AND KANT Even if we are inclined to view Hume's attempt to explain ascriptions of personal identity as an abysmal failure, we might still be sympathetic toward his proposal to replace the going substance theory of the nature of mind with his bundle account. Thus we might fault Hume for erecting an unachievably high standard for personal identity, or round on him for excluding bodily criteria (...) 2... from his solution, but nonetheless applaud his spiriting away of the Cartesian soul substance leaving his "true idea of the human mind" (261) as a collection of perceptions in its stead. However, Hume's concern to give an account of the idea of the unity of a human mind in terms of related perceptions has run into notoriously rough sledding, not the least of which is the fact that Hume himself in his Appendix to "Of Personal Identity" seems to abandon his bundle theory in despair. In this paper I shall first be concerned to examine the criticism of his bundle theory which Hume brings forth in the Appendix and explain why I think the core difficulty remains insoluble for Hume. I shall then go on to suggest that the unworkability of Húmete bundle theory is directly tied to his failure to appreciate certain features of the peculiarly first person nature of his question about the make-up of minds. In thus emphasizing the place of the first person voice in my interpretation I am stealing a leaf, if not a chapter, from Kant. But this is as it should be since one of the aims of this essay is to provide an interpretation of Hume's difficulties with his account of the nature of mind which explains part of the reason why 'self-consciousness' (or 'apperception') looms so very large in the Critique of Pure Reason attack upon Hume's type of bundle theory. 60. 1. Hume's Second Thoughts In a burst of self criticism at the Appendix to the section on personal identity, Hume brings forth this objection to his own efforts:...Having thus loosen' d all our particular perceptions, when I proceed to explain the principle of connexion, which binds them together, and makes us attribute to them a real simplicity and identity; I am sensible, that my account is very defective, and that nothing but the seeming evidence of the precedent reasonings cou'd have indue' d me to receive it (635). After additional reflections Hume encapsulates his objection thus:...All my hopes vanish, when I come to explain the principles, that unite our successive perceptions in our thought or consciousness (6SS-6). What is the defect Hume calls to our attention? Notice first that the footnote on page 635 explicitly refers us back to that part of his account Hume considers defective; and when we look back to the text of the Treatise in question, page 260, we find it is precisely there that Hume uses the analogy of a republic to sketch his bundle theory of the unity of mind in terms of the two associative principles, resemblance and causation. So it must somehow be that this account in terms of the associative principles is mistaken. But what then is the mistake? According to Hume it is that he cannot 'explain' the principles which unite the discrete percepts. Now it seems to me there are only two possible things Hume could mean in saying this. He could mean either (1) that the principles which connect the percepts of one mind are instances of the associative principles, but he cannot explain them; or (2) there must be other, non-associative, principles which connect the percepts of a single mind and these he cannot explain. 61. I think we can safely conclude (1) cannot represent Hume's misgivings when he says he is unable to explain the uniting principles of the mental bundles. There is first the fact that he does not call into question his general programme of accounting for the nature of the unity of complex things by the principles of causation, resemblance and contiguity — for example, ships, plants, animals, houses and rivers (e.g. 257f) — but only his...

This is a comprehensive and appreciative account of Dewey’s philosophy of value. It succeeds in rectifying certain current misconceptions of Dewey’s aims and contributions to moral philosophy, and in clearly presenting a coherent theory of value. Gouinlock begins his account by laying stress upon Dewey’s Experience and Nature as a key to Dewey’s thought. Chapter 1 is devoted to this task. It is held that "Dewey develops and articulates an inclusive philosophy by characterizing such things as art, science, and value (...) with a common set of concepts denoting the generic traits of experience." There is also a discussion of Dewey’s philosophic method and the uses and abuses of experience. Chapter 2 deals with man and nature and Dewey’s critical response to bifurcation between mind and body, and the relation between individual and society. Chapter 3 begins with Nature and Value. Here one finds a good discussion of ends-in-view and values. A great stress is laid on Dewey’s use of metaphysical concepts in value analysis, in particular the needed stress on the inclusive unity of means and end. (shrink)

This short history of Pembroke College, Cambridge appeared in 1936, during a particularly successful period for the college in terms of both academic and sporting achievements. Pembroke was founded in 1347, when Edward III granted Marie de St Pol, widow of the Earl of Pembroke, a licence for the foundation of a new educational establishment in the young University of Cambridge. The college flourished, and from the mid-nineteenth century expanded greatly. The author of this book, which is still regarded as (...) the 'official history of Pembroke College', was a leading authority on the college's history. However, he died before the manuscript could be completed, and the final part was written as a postscript by S. C. Roberts, a former Master of the college. The book has delightful illustrations and a thorough index of the influential scholars, former students and benefactors connected with the college over the centuries. (shrink)

Originally published in 1904, Whittaker’s A Treatise on the Analytical Dynamics of Particles and Rigid Bodies soon became a classic of the subject and has remained in print for most of these 108 years. In this paper, we follow the book as it develops from a report that Whittaker wrote for the British Society for the Advancement of Science to its influence on Dirac’s version of quantum mechanics in the 1920s and beyond.

Robert Kilwardby occupies an important place in the history of logic, and the history of western thought more generally. Perhaps best known to scholars for his Oxford condemnations of 1277...

"One basic and underlying assumption of this investigation will be that there is a distinct continuity and development in Berkeley's thought which can be traced through all of his reflective analyses of the problem of perception." The essay argues for Berkeley's theory of perception as a "prototype of the phenomenalists." It argues also for Berkeley's incorporation of elements from the representative theory of perception. Of special interest is the treatment of Berkeley's doctrine of "suggestion" and its connection with the role (...) of imagination in the perception of physical objects. The linguistic aspect of Berkeley's work is minimized. Berkeley's theory of notions receives only a passing reference. The last third of the book is a clear and useful discussion of Berkeley and contemporary phenomenalism. It is suggested, though not shown, that Berkeley has affinity with contemporary phenomenology of perception.--A. S. C. (shrink)

This target article draws together two groups of experimental studies on the control of human movement through peripheral feedback and centrally generated signals of motor commands. First, during natural movement, feedback from muscle, joint, and cutaneous afferents changes; in human subjects these changes have reflex and kinesthetic consequences. Recent psychophysical and microneurographic evidence suggests that joint and even cutaneous afferents may have a proprioceptive role. Second, the role of centrally generated motor commands in the control of normal movements and movements (...) following acute and chronic deafferentation is reviewed. There is increasing evidence that subjects can perceive their motor commands under various conditions, but that this is inadequate for normal movement; deficits in motor performance arise when the reliance on proprioceptive feedback is abolished either experimentally or because of pathology. During natural movement, the CNS appears to have access to functionally useful input from a range of peripheral receptors as well as from internally generated command signals. The unanswered questions that remain suggest a number of avenues for further research. (shrink)

Unlike its predecessors, this systematic survey of the law of Athens is based on explicit discussion of how the subject might be studies, incorporating topics such as the democratic political system and social structure. Technical and legal terms are explained in a comprehensive glossary.

An excellent collection of lectures. The collection consists of the following: Carl C. Hempel, "On the Structure of Scientific Theories"; W. V. Quine, "Stimulus and Meaning"; Stuart Hampshire, "Aesthetic as the Middle Ground"; H. D. Aiken, "On the Concept of a Moral Principle"; J. O. Urmson, "Utilitarianism"; John Wild, "Is There an Existential A Priori?"; Aron Gurwitsch, "The Husserlian Conception of the Intentionality of Consciousness"; Quentin Lauer, "The Phenomenon of Reason"; and Walter Kaufmann, "The Riddle of Oedipus: Tragedy and Philosophy." (...) These essays represent original contributions to philosophy of science, ethics, and phenomenology and existentialism.--A. S. C. (shrink)

The title of this book is somewhat misleading. A more apt title would have been, "A Marxist Critique of Husserl’s Nullification of the Real World." Such a title would have made the central argument and underlying concern in the present discussion more explicit. The author is intent on a spirited refutation of Husserl’s phenomenology as a transcendental, phenomenological idealism. It is particularly this stage of Husserl’s phenomenological development, maintains Sang-Ki Kim, that effects a sacrifice of the real world. The belated (...) return to the life-world, characteristic of Husserl’s later thought, does not, according to the author, help matters much. Husserl’s analysis of the life-world continues to be informed by the anti-historical apriorism that defined his earlier program of phenomenological idealism. Husserl’s concept of the life-world thus remains a bloodless abstraction, bereft of any acknowledgement of the concrete, historical, naturalist-materialist basis that undergirds it. (shrink)

Volume 41, Issue 3, August 2020, Page 301-303.

For scholars of American philosophy, this anthology of essays on S. C. Pepper's works on metaphysics, aesthetics, and value theory is especially a welcome one. Also included is a reprint of a little known but valuable essay by Pepper entitled "Metaphor in Philosophy," which originally appeared in volume 3 of Phillip S. Wiener's Dictionary of the History of Ideas. In this essay, Pepper discusses his root metaphor theory in relation to Bacon and Kant, and some contemporary uses of the notion (...) of paradigm, e.g., Wittgenstein and Kuhn. Lewis E. Hahn's "The Stephen C. Pepper Papers, 1903-1972" gives an informative account of six book-length unpublished manuscripts in the Pepper Archives at the Southern Illinois University. The rest of the essays concentrate on the various aspects of Pepper's works. A few deal with aesthetic theory and its application to critical practice. Of philosophical interests are papers by Elmer H. Duncan, David B. Richardson, Robert J. Yanal, Robert L. Armstrong, and Brian Caraher, and a short essay by Charles Hartshorne and a response by Joseph H. Monast. Duncan gives a just but critical account of the neglect of Pepper's Sources of Value, and a highly appreciative appraisal of Pepper's World Hypotheses. Caraher's careful essay on the conflicting root metaphors in Frege's theory of meaning offers interesting application of Pepper's conception of formism and contextualism to problems in Frege's philosophy. A variety of problems such as the root metaphor theory, descriptive definition and aesthetic experience are discussed. Efron's long introductory essay entitled "Pepper's Continuing Value" serves its purpose well in terms of indicating Pepper's influence in non-philosophical disciplines and the problems that arise in Pepper's value theory. What is missed is a sustained critical examination of Pepper's root metaphor theory, characterization of the various world hypotheses including Pepper's own selectivism, and its relation to ethical theory. The anthology however is useful in indicating the scope of Pepper's influence and the need to examine his contributions with reference to contemporary philosophical problems.--A.S.C. (shrink)

This interesting and original essay deals with the sense in which the self is a problem, i.e. the sense in which the self poses a problem. The central thesis is carefully argued: "that if there is a problem of the self, its solution is that self is a problem." Central to the thesis is the distinction between persons and selves. The concept of a person is in Heideggerian terms "ontic" in the sense that it does not arise from any theoretical (...) concern. The concept of self is an "ontological" one. Chapter one argues for the assumption that "persons can be generally inconsistent" and for the distinction between computers and persons. In Chapter two, "the self" is defined as "the locus of the inconsistency." The remaining essays deal with the problems of identity, immortality, consciousness and the pivotal role of the self in philosophical controversy. The book is clearly written and its thesis is carefully supported by arguments. It is an original contribution to the philosophy of mind.--A. S. C. (shrink)

This new addition to the series New Studies in Practical Philosophy edited by W. D. Hudson is a study of deontic moral judgment, in particular of moral concepts which embody standards for the assessment of claims to right or wrong actions. Three main theses are quite clearly stated. The first thesis concerns the distinctive character of the moral point of view which is irreducible to either logical or factual considerations. The second thesis is that moral judgments claim interpersonal validity in (...) the sense that the speaker makes the implicit claim that every reflective agent who considers the judgment "ought to agree" with the judgment as a correct one. The third thesis pertains to the moral disagreement. It is maintained that moral disagreements are "in principle" decidable, not by way of deductive subsumption under the criteria governing the uses of moral concepts, but by a method of inquiry analogous to that of scientific inquiry involving the use of hypothesis. The author acknowledges his debt to Arthur Prior, J. Kovesi, and M. Polanyi. The book is good in raising questions on the relation between moral inquiry and scientific inquiry, the significance of the open texture of moral terms and its relation to ethical argumentation, and the problem of reconciling differences of moral beliefs in the setting of their connection with nonmoral beliefs.—A.

A lucidly written and original contribution to the study of the concept of expression. "The aim has been to construct an analysis from the examination of typical forms of human expressions and from the logical implications of our description of such expressions." An interesting theory emerges from such an analysis in Chapters I and II. The theory is "extended to language in Chapter III and to art in Chapters IV and V." Chapter I deals with behavior and expression and plausibly (...) argues for the thesis that intentionality is characteristic of expressible states of the person and that these expressions are "noncontingently connected with behavioral patterns associated with them." Chapter II takes up the topic of inference. It begins with the distinction between "Ø-expression" and "expression of Ø." The former is claimed to be a "description of certain observable features of a situation;" and the latter is an "inference warranting expression, relating some intentional state of a person to particular aspects of his observable behavior." It is argued that the nature of warrantable inference is non-causal, but "one which moves from a part of a conceptual complex to another part, or to the whole of it." Chapter III contains a good discussion of the distinction between belief and opinion, expressive and performative uses of language. The chapter concludes with the statement that "linguistic expression, like its behavioral counterpart, preserves an inferential connection with intentional states of the person." The last two chapters deal with art as expression. The appendix contains quotations from prominent expression theorists. A useful bibliography is also provided.--A. S. C. (shrink)
