In standard Wheeler-Feynman electrodynamics advanced waves from any source are absolutely canceled by the advanced waves from the absorber responding to that source. The present work shows this cancellation fails over cosmic distances in a steady-state universe. A test of the view proposed earlier, in a paper which assumed failure of cancellation and hoc, that zero-point fluctuations of the electromagnetic field are such emergent advanced waves, is posed. The view entails anomalous slowing of spontaneous transition rates at longer emission wavelengths; (...) available data go against this, furnishing additional argument against the suspect assumption that the universe is steady-state.

The experience of newborn screening for Krabbe disease in New York State demonstrates the ethical problems that arise when screening programs are expanded in the absence of true understanding of the diseases involved. In its 5 years of testing and millions of dollars in costs, there have been very few benefits, and the testing has uncovered potential cases of late-onset disease that raise difficult ethical questions in their own right. For these reasons, we argue that Krabbe screening should only be (...) continued as a research project that includes the informed consent of parents to the testing. (shrink)

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)

Recent experimental findings reveal dissociations of conscious and nonconscious performance in many fields of psychological research, suggesting that conscious and nonconscious effects result from qualitatively different processes. A connectionist view of these processes is put forward in which consciousness is the consequence of construction processes taking place in three types of working memory in a specific type of recurrent neural network. The recurrences arise by feeding back output to the input of a central (representational) network. They are assumed to be (...) intemalizations of motor-sensory feedback through the environment. In this manner, a subvocal-phonological, a visuo-spatial, and a somatosensory working memory may have developed. Representations in the central network, which constitutes long-term memory, can be kept active by rehearsal in the feedback loops. The sequentially recurrent architecture allows for recursive symbolic operations and the formation of (auditory, visual, or somatic) models of the external world which can be maintained, transformed and temporarily combined with other information in working memory. Moreover, the quasi-input from the loop directs subsequent attentional processing. The view may contribute to a formal framework to accommodate findings from disparate fields such as working memory, sequential reasoning, and conscious and nonconscious processes in memory and emotion. In theory, but probably not very soon in practice, such connectionist models might simulate aspects of consciousness. (shrink)

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.

Beginning with an overview of Galileo's earliest work on free fall, the paper examines the relationship between experiment and theory in his study of motion in the period immediately before and after 1604. The possible role of experiment is assessed in relation to the manuscript evidence and by means of reconstructed experiments.

The paper uses questionnaire responses provided by a sample of ethical investors to investigate willingness to sacrifice ethical considerations for financial reward. The paper examines the amount of financial reward necessary to cause an ethical investor to accept a switch from good ethical performance to poor ethical performance. Conjoint analysis is used to allow quantification of the utilities derived from different combinations of ethical and financial performance. Ethical investors are shown to vary in their willingness to sacrifice ethical for financial (...) performance, and hence to display more heterogeneity than the all-encompassing ‘ethical’ label implies. Because of the existence of sub-groups of ethical investors with different attitudes towards financial reward, an attempt has been made to associate observable investors’ characteristics with their level of willingness to trade-off morality for cash. One sub-group of investors in particular appears highly resistant to the idea of accepting higher financial return as compensation for poor ethical performance. This unwillingness casts doubt on Jensen and Meckling’s widely reported claim that trade-off behaviour is ubiquitous in all areas of life. (shrink)

Suzanne Langer's earlier works on the philosophy of art, particularly her Feeling and Form, are the points of departure for this general study of the phenomena of life and mind which she clearly intends to be her magnum opus. This is the first of two volumes, the second volume as yet unpublished. Her main thesis is that the "departure [of man] from the normal pattern of animal mentality is a vast and special evolution of feeling in the hominoid stock". She (...) opposes all attempts to bifurcate nature into matter and mind, and in this regard aligns herself with the main currents of contemporary thought. But the centrality she gives to the notion of feeling is uniquely her own, separating her views from those of most other contemporary thinkers and providing the most controversial part of her book. In different places throughout the work, the term "feeling" includes within its scope "sensation," "inward tension," "pain," "emotion," "intent," and a number of other phenomena. Critics of the work will no doubt argue that the theory cannot overcome the vagueness engendered by giving this central concept such a wide scope. But before making a final judgment on this point they will have to pay special attention to the second and third parts of this book where her concept of feeling slowly takes shape through reflection on the arts and on the nature of living things. In a second volume she promises to move beyond living things in general to the distinctive features of human consciousness. A second respect in which this work differs from much other writing in the philosophy of mind is the wealth of references and examples from the biological and psychological sciences which display the encyclopedic interests and openness which have always characterized Suzanne Langer's writings.--R.

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)

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 existence of consciousness in animals may have been overlooked. Continuity in consciousness between humans and animals is predicted by evolutionary theory. However, there are specific methodological difficulties associated with investigating such a phenomenon: it cannot be directly measured; animals, unlike humans, cannot directly tell us about their conscious experience; experiments which have made comparisons to human consciousness cannot detect consciousness of a different form; application of the law of parsimony in science has traditionally led to the conclusion that it (...) does not exist.
