Fourteen essays are here collected from a number of periodicals. Six deal with the relations between language and the world, two with rules, one with possibility, two with causation, one with time, and two with the "problem of induction." In an appendix, Prof. Black notes various objections that have been made to his views. Though some of the essays are rather slight, a number of valuable points are made, and the volume on the whole is quite useful. --J. B. S.

This little volume, using a combined approach of phenomenology, history, philosophy, and theology probes deeply into questions of belief and commitment. The book is valuable for scholars who possess the background and sensitivity to appreciate the three essays which constitute it. The first of these, "The Structure of Jewish Experience," takes up the epistemological problem of belief in a God who is present in history and who can consequently be the object of worship by modern man just as he was (...) thousands of years ago. The second essay, "The Challenge of Modern Secularity," deals with current theological issues, including the Subjectivist Reductionism, the "Death" of God, and faith as "immediacy after reflection." The third and most impassioned essay, "The Commanding Voice of Auschwitz," deals with themes which have been the preoccupation of Elie Wiesel, to whom the book is dedicated. There have not been many Jewish writers since the holocaust, who have been willing to write about their faith. Fackenheim speculates that it must be difficult to justify such faith to oneself in light of the fate of the Jews in recent history. In this book, and particularly in the last essay, the author attempts to justify such faith, and he does it intelligently and eloquently.--S. J. B. (shrink)

Wood informs the reader that Buber rejected "isms," hard and fast rules and principles, and systems, but he goes on to systematize Buber's thought nonetheless. The result is often enlightening. I and Thou, which Wood considers the central work of the philosopher's thought, is finely broken down and analyzed in its component parts. In this manner it is less formidable to the uninitiated, and the reader who is puzzled by a particular passage can find in Wood's book an authoritative, well-researched (...) explanation. There are also excellent biographical data woven in with glimpses of Buber's voluminous works and the influences on them, and a complete bibliography that is as definitive as any published to date. But Buber's thought does not lend itself to systematization. One cannot substitute Ontology for Metaphysics and then proceed to dissect a philosophy which declares itself to be beyond metaphysics, and which points to the existential meeting of a person here and now with another person and/or with God. Wood provides a diagram showing the structure of I and Thou which may be useful for locating selections in the book as they relate to a certain code, but at the same time it illustrates what Buber describes as objectification, an I-it relationship with a person or his work, which is far from the I-Thou relationship.--S.

This work contains three essays which were delivered at a Symposium in 1966 at the Free University in Brussels, convened to pay homage to Martin Buber. The first essay, by Gabriel Marcel, attempts to edify the reader on Buber's philosophical anthropology, his philosophy of dialogue, political philosophy, and his philosophy of religion. There are frequent comparisons between Marcel's point of view and Buber's. The essay is particularly strong where Marcel analyzes Buber's notion of the "we." His perceptive examination of this (...) subject points up the affinity between his own and the Jewish philosopher's thought. The essay by Emmanuel Levinas, "La Pensée de Martin Buber et le Judaïsme Contemporain," sketches current Jewish thought and finds that it was Buber who gave it direction. Levinas provides also an account of the enormous work which Buber did in establishing Hassidism as an important stage in Hebraic thought. The last essay, by André Lacocque, deals with Protestant theology and the possible application of Buber's ideas to it. There is an extended comparison between the views of Kierkegaard and those of Buber on man's relationship with God and the author concludes that Buber's point of view is more compatible with modern Christianity than was Kierkegaard's.--S.

An important contribution both to the philosophical literature concerned with the problem of free choice and to the growing field of investigation dealing with self-referential argumentation. The authors have attempted to weave these two areas of interest together, in the hope of advancing philosophical knowledge in both. The book’s approach to the problem of free choice by means of self-referential argumentation will constitute a milestone for future efforts which have this double, or either special, focus.

Woodger's substitution of the "allegedly more precise term 'an environmentally insensitive set of lives'" for the term 'an inborn character' is discussed by haldane. He proposes that "woodger's definitions do not appear to have reached precision." (staff).

Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing photon budget during the epoch of reionization, but their escaping photons cannot be detected directly due to inter-galactic medium opacity. Hence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum photon leakage up to z 4 to (...) define indirect indicators allowing analogues to be found at the highest redshift. Aims. Long gamma-ray bursts explode typically in star-forming regions of faint, star-forming galaxies. Through LGRB afterglow spectroscopy it is possible to detect directly LyC photons. Our aim is to use LGRBs as tools to study LyC leakage from faint, star-forming galaxies at high redshift. Methods. Here we present the observations of LyC emission in the afterglow spectra of GRB 191004B at z = 3:5055, together with those of the other two previously known LyC-emitting LGRB, to determine their LyC escape fraction and compare their properties. Results. From the afterglow spectrum of GRB 191004B we determine a neutral hydrogen column density at the LGRB redshift of og =17:2 0:15, and negligible extinction. The only metal absorption lines detected are C iv and Si iv. In contrast to GRB 050908 and GRB 060607A, the host galaxy of GRB 191004B displays significant Ly emission. From its Ly emission and the non-detection of Balmer emission lines we constrain its star-formation rate to 1 SFR 4:7 M yr. 1. We fit the Ly emission with a shell model and find parameters values consistent with the observed ones. The absolute LyC escape fractions we find for GRB 191004B, GRB 050908 and GRB 060607A are of 0:35+0:10.0:11, 0:08+0:05.0:04 and :20+0:05.0:05, respectively. We compare the LyC escape fraction of LGRBs to the values of other LyC emitters found from the literature, showing that LGRB afterglows can be powerful tools to study LyC escape for faint high-redshift star-forming galaxies. Indeed we could push LyC leakage studies to much higher absolute magnitudes. The host galaxies of the three LGRB presented here have all M1600 >.19:5 mag, with the GRB 060607A host at M1600 >.16 mag. LGRB hosts may therefore be particularly suitable for exploring the ionizing escape fraction in galaxies that are too faint or distant for conventional techniques. Furthermore the time investment is very small compared to galaxy studies. (shrink)

Passmore examines a number of kinds of argument frequently used by philosophers, in an attempt to find out whether there is any kind of reasoning which is especially appropriate for philosophy. He discusses the ways in which philosophers have used deduction, induction, reminders about obvious facts, infinite regress arguments, paradigm case arguments, claims that certain views are self-refuting, and accusations of meaninglessness. Numerous illustrations of these moves in argument, drawn from philosophers from Plato to Popper, help to make this an (...) interesting essay in the philosophy of philosophy.--J. B. S. (shrink)

John Burdon Sanderson Haldane was a giant among men. He made major contributions to genetics, population biology, and evolutionary theory. He was at once comfortable in mathematics, chemistry, microbiology and animal physiology. But it was his belief in education that led to his preparing his popular essays for publication. In his own words: "Many scientific workers believe that they should confine their publications to learned journals. I think that the public has a right to know what is going on inside (...) the laboratories, for some of which it pays." So begins Haldane's collection of essays, perhaps the most public intellectual communicating science before the writings of Stephen Jay Gould. The first part of the volume emphasizes the important developments in biology and natural science in the first quarter of the century. As such, it provides a benchmark for studies of the next three quarters of the century. In an unusual introduction, Price takes the readers through their paces, discussing the situation then and now in vitamins, oxygen want, disease controls, and the rewards of science as such. This is followed by Haldane's views on society, art, religion and economy as seen through the eyes of a politically alert major scientist. The editor provides readers unfamiliar with Haldane with a carefully rendered chronology of a life that began in 1892 and that spanned much of the present century. Despite ideas on race, class and politics that have seen better times, Haldane was truly exceptional in translating the science of his time into ideas that "everyman" could readily grasp. His predictions on what science would achieve were on target far more often than not. But even his failed predictions are perhaps the most interesting of all. They throw into sharp relief the truly novel and revolutionary developments in science over the past 75 years. J.B.S. Haldane held many positions and received many honors during his lifetime. But for most of the period covered in this volume, he was the William Dunn Reader in Biochemistry at Cambridge University. He simultaneously served as Fellow of New College, in Oxford University's Horticultural Institute. Carl A. Price served until 1999 as professor IIof plant molecular biology in the Waksman Institute of Microbiology at Rutgers, the State University of New Jersey. He also served as the editor of Plant Molecular Biology Reporter from 1983 until 1997. This is the first volume in a new series on the history and theory of science. (shrink)

Adopting a noncognitivist metaethics, Smart presents hedonistic-act utilitarianism as a position which appeals to benevolent and sympathetic men. He renounces any attempt to prove the position, but he does try to show that it is not open to the usual objections. There are some interesting comments on the concept of happiness and a brief attempt to show a way in which game theory can be used in a utilitarian position.--J. B. S.

Reasoning under uncertainty, that is, making judgements with only partial knowledge, is a major theme in artificial intelligence. Professor Paris provides here an introduction to the mathematical foundations of the subject. It is suited for readers with some knowledge of undergraduate mathematics but is otherwise self-contained, collecting together the key results on the subject, and formalising within a unified framework the main contemporary approaches and assumptions. The author has concentrated on giving clear mathematical formulations, analyses, justifications and consequences of the (...) main theories about uncertain reasoning, so the book can serve as a textbook for beginners or as a starting point for further basic research into the subject. It will be welcomed by graduate students and research workers in logic, philosophy, and computer science as a textbook for beginners, a starting point for further basic research into the subject, and not least, an account of how mathematics and artificial intelligence can complement and enrich each other.

Biologists have as yet taken but little cognizance of the revolution in human thought which has been inaugurated by physicists in the last five years, and philosophers have stressed its negative rather than its positive side.

Conscious events interact with memory systems in learning, rehearsal and retrieval (Ebbinghaus 1885/1964; Tulving 1985). Here we present hypotheses that arise from the IDA computional model (Franklin,Kelemen and McCauley 1998; Franklin 2001b) of global workspace theory (Baars 1988, 2002). Our primary tool for this exploration is a flexible cognitive cycle employed by the IDA computational model and hypothesized to be a basic element of human cognitive processing. Since cognitive cycles are hypothesized to occur five to tentimes a second and include (...) interaction between conscious contents and several of the memory systems, they provide the means for an exceptionally fine-grained analysis of various cognitive tasks. We apply this tool to the small effect size of subliminal learning compared to supraliminal learning, to process dissociation, to implicit learning, to recognition vs. recall, and to the availability heuristic in recall. The IDA model elucidates the role of consciousness in the updating of perceptual memory, transient episodic memory, and procedural memory. In most cases, memory is hypothesized to interact with conscious events for its normal functioning. The methodology of the paper is unusual in that the hypotheses and explanations presented are derived from an empirically based, but broad and qualitative computational model of human cognition.
