As interest in working memory is increasing at a rapid pace, an open discussion of the central issues involved is both useful and timely. This new volume compares and contrasts conceptions of working memory, with contributions from proponents of different views.

This paper reports a study of planning processes in the five-disc Tower of London (TOL) task in 20 younger and 20 older adult participants. A concurrent direct ''think-aloud'' method was used to obtain data on planning processes prior to moving discs in the TOL. A check was made of the effects of verbalising by comparing performance data from the experimental groups with data from control groups who did not verbalise during planning or moving. Verbalising slowed down planning and moving but (...) did not appear to distort the participants' approaches to the task. Older and younger participants did not differ in average moves taken to solve the tasks. However, older participants' planning was less complete and more error-prone than that of younger participants. The planning processes were characterised as showing a means-ends ''goal selection'' strategy. In this strategy participants (1) identify a single active goal disc at the start, (2) select moves and move sequences to enable the placing of the current goal disc in its target position, and (3) continue in this way until all discs are in their target positions. Age differences were found in the planning stage, during which there was no stimulus support and hence a substantial working memory load. During the move phase there was stimulus support and hence little loading of working memory. Age differences in moves required were not found in the move phase. As older participants tend to have depleted working memory capacity the present results suggest that working memory is heavily loaded in TOL planning but less so in the move phase of TOL. (shrink)

This paper reports a study of the roles of visuo-spatial and verbal working memory capacities in solving a planning task - the five-disc Tower of London (TOL) task. An individual differences approach was taken. Sixty adult participants were tested on 20 TOL tasks of varying difficulty. Total moves over the 20 TOL tasks was taken as a measure of performance. Participants were also assessed on measures of fluid intelligence (Raven's matrices), verbal short-term storage (Digit span), verbal working memory span (Silly (...) Sentence span), visuo-spatial short-term storage (Visual Pattern span and Corsi Block span), visuo-spatial working memory (Corsi Distance Estimation), visuo-spatial processing speed (Manikin test), and verbal speed (Rehearsal speed). Exploratory factor analysis using an oblique rotation method revealed three factors which were interpreted as (1) a visuo-spatial working memory factor, (2) an age-speed factor, and (3) a verbal working memory factor. The visuo-spatial and verbal factors were only moderately correlated. Performance on the TOL task loaded on the visuo-spatial factor but did not load on the other factors. It is concluded that the predominant goal-selection strategy adopted in solving the TOL relies on visuo-spatial working memory capacity and particularly involves the active ''inner scribe'' spatial rehearsal mechanism. These correlational analyses confirm and extend results previously obtained by use of dual task methods, (Phillips, Wynn, Gilhooly, Della Sala, & Logie, 1999). (shrink)

Levi in this book develops the views on inductive logic which he put forward in 1967 in Gambling with Truth. He extends the account given there of inductive expansion and supplements it with an account of routine expansion and contraction with the aim of constructing a view of how revisions of bodies of knowledge should be evaluated. He is concerned to give an account of the revision of probability judgments and gives the contexts of specific enquiries an important place in (...) critical appraisal of changes in cognitive commitment.

After a condensed and lucid summary of Classical Psychoanalysis, this Indian philosopher applies the criterion of self-referential consistency to criticize Freud's application of psychoanalytic categories to the phenomenon of religion. Professor Masih argues that Freud's account of religion fails to account for other religions than Monotheism. He interprets this desire to dethrone the God of Monotheism as a consequence of Freud's repressed father-hatred and extends this technique of psychoanalyzing Freud to see in his metaphysics of materialism a subconscious love of (...) the mother. There are elements of experience that transcend any psychoanalytic account of that experience. Whereas neurosis is necessarily infantile, the infantile aspects of such adult experiences as religion is not necessarily neurotic. Freud's genius in developing the psychoanalytic method is a case in point. Masih then argues that Freud's mistaken application of this method of treating individuals to social phenomena involves regression into a neurotically determined prejudice. The final irony is that even Freud's psychoanalytic method has the religious dimension of a humanistic concern for man's salvation from illness.—T. R. H. (shrink)

The Protestant ethic — a moral code stressing hard work, rigorous self-discipline, and the organization of one's life in the service of God — was made famous by sociologist and political economist Max Weber. In this brilliant study (his best-known and most controversial), he opposes the Marxist concept of dialectical materialism and its view that change takes place through "the struggle of opposites." Instead, he relates the rise of a capitalist economy to the Puritan determination to work out anxiety over (...) salvation or damnation by performing good deeds — an effort that ultimately discouraged belief in predestination and encouraged capitalism. Weber's classic study has long been required reading in college and advanced high school social studies classrooms. (shrink)

Recent studies have pointed to the existence of a strong relationship between memory and mental representation, while others have shown that images are open to reinterpretation and manipulation; this volume offers a historical overview of the problem as well as a review of the research in psychology and related fields.

This second volume in the series designed to review the work done in various areas of philosophy during the period 1956-1966 is concerned with the philosophy of science. There are forty essays on a variety of topics in the philosophy of science describing the work done in that area in the past decade and a bibliography covering the same period. Most are in English, some in French or German. Some representative topics and their authors are: Laws, Models, Causality, Induction and (...) Probability, Scientific Methodology, Time, Space, Cosmology, Philosophy and Physics, Quantum Theory, Biology and Philosophy. In addition there are several general essays on the influence of various philosophers and scientists on current developments in the philosophy of science, on the ethical and philosophical implications of science, on Cybernetics, Information Theory, Game theory and a number of essays on the development of philosophy of science in different countries of Western and Eastern Europe and Japan. Like the first volume of this series, this book is an indispensable guide to anyone interested in the field, and a place should be made for it on every library shelf---where there is an interest in philosophy of science.--R.

Since the bulk of this book is devoted to paraphrasing Aristotle's physical views for modern ears, it would have been more correctly styled an exposition or synopsis. As such, the work is of some value and may prove particularly helpful as an introduction. Though many of his expository comments are quite sensitive, the author takes for granted an uncritical acceptance of nineteenth century mechanics in those passages which attempt critical assessment of peripatetic natural science.—R. H. T.

The title essay was originally presented as two lectures inaugurating the John Dewey lectures at Columbia. It is an important essay for understanding Quine's work for it brings together many themes at the center of his thinking since Word and Object. Quine quotes with approval Dewey's statement "meaning is primarily a property of behavior" and then goes on to consider a thesis which, according to Quine, is a consequence of such a behavioral theory of meaning, i.e., the thesis of the (...) indeterminacy of meaning and translation. Quine relates this indeterminacy thesis, which he has been defending for some time, to language learning, the foundations of mathematics, and to a general view of ontological relativity. Other essays in the volume concern natural kinds and the various paradoxes of confirmation, propositional objects, quantification and existence and the empirical basis of science. All the essays are post-1965 except the introductory essay which was Quine's Presidential Address to the Eastern Division of the American Philosophical Association in 1956. This address was something of an introduction to the ideas to appear in Word and Object and is placed at the beginning of this collection to emphasize that all the essays collected here expand on and defend some of the positions of Word and Object. Quine's fluid style is everywhere in evidence.--R. H. K. (shrink)

This revised version of Price's 1960 Gifford Lectures in two series at Aberdeen University presents an extensive analysis of the concept of belief and related problems. The author begins by exploring different senses of knowledge. He continues to examine some logical peculiarities of expressions about believing and knowing, of relationships between the two types of expressions, and remarks on the performatory aspects of the relevant expressions. Connections between believing, and the bearing on beliefs of perceptual evidence, self-consciousness, memory and testimony (...) are examined. The results of this examination are applied to introduce systematic distinctions and concepts, which are made constitutive of the concept of belief. The notion of degrees of belief is introduced. The problem of degrees of assent is examined in the context of Newman's criticisms of Locke's view. Specific theories of belief are surveyed, beginning with Hume's theory, and two traditional occurrence analyses of belief are touched upon. The first series is concluded with a brief examination of Descartes' and Hume's views on freedom of assent. The second series examines various dispositional analyses of belief; the notions of believing and "acting as if" are compared, and the connection between inference and assent examined. The notion of half-belief is reviewed, along with Newman's distinction between real and notional assent, and James' self-verifying beliefs. The second series concludes with a discussion of moral beliefs and feelings; belief "in" and belief "that" are compared, and the possibility of a rapprochement between religious belief and empiricist philosophy is examined. While the author offers no full-blown theory of belief--and does not purport to do so--he provides a most informative discussion of the matrix of epistemological and psychological problems called belief, offers new criticisms of both older and present-day views on persisting problems for belief-analysis, and refines these views with new distinctions and concepts.--J.

This is the first of a number of volumes designed to review the philosophical work which has been done in various areas of philosophy between the years 1956 and 1966. It succeeds an earlier three volume publication entitled Philosophy in the Mid-Century which covered the period from 1949 to 1955. This first volume in the series covers the fields of logic, philosophical logic, foundations and philosophy of mathematics. For anyone interested in these fields, the book is an indispensable guide. The (...) procedure is that an expert in a given area writes a summary of the work done in the area in the last ten years and adds a bibliography covering the same period. In all there are thirty-two such essays, most written in English, but a few in French and German. Some representative essays and their authors are the following: On the logical side, Modal Logic, Many Valued Logics, Logic of Practical Discourse, Semantics, Model Theory, Pragmatics, Chronological or Tense Logic, The Logic of Questions, Combinatory Logic and others. There are two general essays on recent developments in philosophical logic and a number of essays on the development of logic in various Eastern and Western European countries and Japan. On the mathematical side are three essays on foundations of set theory and mathematics, essays on Intuitionism in mathematics, and general essays by A. Church, H. Freudenthal and others. The essays are generally of high caliber and the bibliographies in most cases very comprehensive. Occasionally the essays contain not only summary of work done but original suggestions and development of ideas. It would be hard to find a more useful guide for the philosopher overwhelmed by the many developments in these fields in recent years.--R. H. K. (shrink)

This piece, included in the drift special issue of continent. , was created as one step in a thread of inquiry. While each of the contributions to drift stand on their own, the project was an attempt to follow a line of theoretical inquiry as it passed through time and the postal service(s) from October 2012 until May 2013. This issue hosts two threads: between space & place and between intention & attention . The editors recommend that to experience the (...) drifiting thought that attention be paid to the contributions as they entered into conversation one after another. This particular piece is from the BETWEEN INTENTION & ATTENTION thread: Jeremy Fernando, Sitting in the Dock of the bay, watching... * R.H. Jackson, Reading Eyes * Gina Rae Foster, Nyctoleptic Nomadism: The Drift/Swerve of Knowing * Bronwyn Lay, Driftwood * Patricia Reed, Sentences on Drifitng * David Prater, drift: a way * * * * The gaze drifts where the stare dares not. The gaze is attentive while the stare is intent. Dériver : Equally to drift and/or to derive. —When drifting then, something must be taken along. Something must be derived from the drift. Something of oneself must always become other. Incorporating the other, incorporating oneself as other. Je est un autre , Rimbaud disait; 1 this in his last letter to Georges Izambard, a final correspondence to a former mentor and friend, from whom he was drifting away, having derived much. The drift is a control incomplete. To drift is to come closer and closer, but to always be turning away, pulling apart, pulling oneself apart. It is parabolic in the sense that it is always eluding a formerly established intent. Of all axes, it never finds room to rest. Filling new spaces, always changing places, ever escaping the Cartesian; the indubitable pinpointing of position. It is never pinned down. Love together what we will be apart. Once together, we will drift apart. Il le faut . Attention is held; it traces the path. It follows each point which traces the arc, the line, the swerve. It is not concerned with the figure being drawn, but rather the movement between one point and the next. The smallest movement. The clinamen of De Rerum Natura is the smallest of swerves, it is nothing more than the minimum — nec plus quam minimum . Michel Serres says of the clinamen , that it is an absurdity — a logical, geometrical, mechanical, physical absurdity. 'The clinamen, from here (its state of absurdity), finds refuge in subjectivity; it passes from the world to the soul, from the physical to the metaphysical, from the theory of inert bodies in freefall to the theory of the free movements of the living.' 2 So this swerve is something of the mind and something of the body, both in action, rather than a body which is merely acted upon. Swerve, however, has a connotation of suddenness. It is a movement which is made to avoid an otherwise inevitable impact. Drift, on the other hand, is the unleashing of something which is then allowed to follow a more complex series of forces. These forces now come from within as well as without. It is no longer tethered; now following tides, winds, flows or pitched slopes, now acting on its own. We are not atoms in freefall. Our attention long ago pulled us from this precipitous descent. We now live, ourselves, as one of the many forces. In the drift, as with the gaze, there is an ease. ‘Ease is the proper name of this unrepresentable space.’ It is the space nearest, the next, the neighboring space. To occupy this space requires a turn, a shift or a drift. It cannot be reached by proceeding straight ahead. ‘..the space adjacent, the empty place where each can move freely, in a semantic constellation where spatial proximity borders on opportune time (ad-agio, moving at ease) and convenience borders on the correct relation.’ 3 Intention always seeks to straighten this line, to make it less complex, to isolate the point of departure and the desired destination. It believes there can be two points and, between them, there must be a straight line. Can there be? Maybe. Must there be? Never. Straight lines may exist, but they can never be followed to the finish. After leaving this point, we will never reach that one without being buffeted at least a little — at least the least. One foot in front of the other, this is a very restrictive dance, less even than a two-step. Straight lines lead only to lost intentions, being the shortest and quickest way to get there. When attention drifts it slowly turns away from the intended target, leaving it for something which pulls the attention away. Now we are for a moment free; all at once we can pivot, now we can waltz. Drifting along the page, deriving from what is seen. Reading is seeing; the movement of the eyes as they drift. Reading in the eyes what has been seen, what has been derived from the act of reading. Reading eyes drift back and forth down the page, now and then jump back and forth, up to the top, one word, back down, quickly a few pages back, now gaze out towards the horizon. When attention drifts it is the gaze that follows. Our attention is not restricted to the path the words follow, but links them together; deriving what is to be seen, rather than read. La philosophie fait voir . ‘Thus, philosophers speak through proverbs, and demonstrate. They connect their imaginations with foreign rings, flown into famous tombs.’ 4 Now drifting off to sleep, dreams come as unintended visions. To dream is pure drift, vision without an object, gazing into the dark, reading the unknown of the night. NOTES: Arthur Rimbaud, Poésies (Paris: Bibliothéque de Cluny, 1958), 57.

Leibniz' General Investigations, a group of memoranda on logical and methodological matters, remained unpublished until Couturat published the original Latin manuscript in 1903. Only after 1960 was a German translation made by F. Schmidt and an English translation by G. H. R. Parkinson. The present translation provides extensive reference notes to Leibniz' other manuscripts, and a commentary and notes to the text. In these respects it has some advantages over previous translations. The translation is clear although the work itself is (...) sometimes difficult to follow and the notes are most welcome. An introduction discusses the place of the General Investigations within the context of Leibniz' thought. With the interest in Leibniz' logical writings very strong at present, this new translation and commentary is most welcome.--R. H. K. (shrink)

In this work R. M. Martin carries his semiotical studies into the fields of intensional semantics and pragmatics, dealing with such philosophically important concepts as meaning, preference, reasonableness and indifference. The crucial notion is that of the meaning or intension of an expression. Two major categories are distinguished, objective intensions and subjective intensions. To deal with objective intensions an intensional semantics is developed as an extension of denotational semantics in the tradition of Tarski, Carnap and Martin's earlier Truth and Denotation. (...) In the treatment of subjective intensions Martin makes an advance over his earlier study of pragmatics by utilizing the work of von Neumann and Morgenstern in their Theory of Games and Economic Behavior.—R.

The first part of this long two-part work is a history of the development of the modern theory of the atom from Dalton to the present. The second part offers philosophical reflections on this history beginning with a discussion of epistemological implications and following that with an account of ontological implications. The author deals with familiar questions about the reality of micro-particles, complementarity, indeterminism, the role of the observer and other topics. But he also discusses topics like holism, atomic order, (...) the intelligibility of matter and others which are less commonly discussed by philosophers in connection with modern physical theories. The author, who is trained in physics as well as philosophy, has a flair for metaphysical speculation as well as wide knowledge of contemporary physical theory. He stresses the novelties of the quantum conception of matter, argues against its critics like Bohm, and sees it as presenting a radically new conception of atomic order despite its commitment to indeterminism. The views of Werner Heisenberg, who encouraged the author to write the book and who read it in manuscript, have clearly influenced the author, although they do not dominate his thinking.--R. H. K.

This monograph offers a crisp, comprehensive summary of the discoveries to date in the field of pre-biological evolution. Supported by extensive references to recent research and quite technical in treatment, the work is comprehensible to any reader with a beginner's knowledge of organic chemistry because the author is careful to focus his discussion around three hypothetical stages of abiotic evolution. The author's argument that the histories of the universe, of the earth, of nature and of man form a continuous evolutionary (...) thread is persuasive, although admittedly an extrapolation based on his conviction in the uniformity of chemical function. The book provides an impressive glimpse into the scope, power and imagination of Soviet scientific research.—T. R. H. (shrink)

The German philosopher Rickert substituted for Hegel's formulation of the dialectic a "Heterological Principle of Thought" where identity and otherness become moments within the pure logical object of thought. The logical object of thought takes precedence over dialectical movement, and otherness takes precedence over negation. Flach expounds and defends Rickert's position against its critics. The discussion is specialized but contains some valuable insights into Hegel. --R. H. K.

This is the first comprehensive study of Schrödinger's scientific and philosophical writings. The task requires a person trained thoroughly in physical science and yet capable of appreciating the sometimes puzzling philosophical ideas Schrödinger put forward. Professor Scott, a physicist, is remarkably successful at communicating both the physical and the philosophical ideas. After a brief summary of Schrödinger's diverse writings, he divides the writings into four groups which are treated in separate chapters. The first group, including very early papers, deals with (...) Schrödinger's work on Statistical Mechanics, and statistical theories in general. The second covers the crucial development of Wave Mechanics. The third concerns Schrödinger's interpretation of quantum mechanics and the important departures from the prevailing views of the Copenhagen school. Finally the fourth group contains Schrödinger's views on life and the self. The author shows that Schrödinger was led to his doctrine of identity by reflecting on the paradox of freedom and determinism. His study "What is Life?" convinced him that living systems are governed by the law of causality but he also believed that men were free. The doctrine of identity was his solution to the paradox. Scott is critical of this solution and a number of other doctrines of Schrödinger. The book is clearly written throughout and is a good introduction to Schrödinger's thought.--R. H. K. (shrink)
