We present evidence disputing the hypothesis that memories are processed or consolidated in REM sleep. A review of REM deprivation (REMD) studies in animals shows these reports to be about equally divided in showing that REMD does, or does not, disrupt learning/memory. The studies supporting a relationship between REM sleep and memory have been strongly criticized for the confounding effects of very stressful REM deprivation techniques. The three major classes of antidepressant drugs, monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), and (...) selective serotonin reuptake inhibitors (SSRIs), profoundly suppress REM sleep. The MAOIs virtually abolish REM sleep, and the TCAs and SSRIs have been shown to produce immediate (40–85%) and sustained (30–50%) reductions in REM sleep. Despite marked suppression of REM sleep, these classes of antidepressants on the whole do not disrupt learning/memory. There have been a few reports of patients who have survived bilateral lesions of the pons with few lingering complications. Although these lesions essentially abolished REM sleep, the patients reportedly led normal lives. Recent functional imaging studies in humans have revealed patterns of brain activity in REM sleep that are consistent with dream processes but not with memory consolidation. We propose that the primary function of REM sleep is to provide periodic endogenous stimulation to the brain which serves to maintain requisite levels of central nervous system (CNS) activity throughout sleep. REM is the mechanism used by the brain to promote recovery from sleep. We believe that the cumulative evidence indicates that REM sleep serves no role in the processing or consolidation of memory.

We believe that this has been a constructive debate on the topic of memory consolidation and REM sleep. It was a lively and spirited exchange – the essence of science. A number of issues were discussed including: the pedestal technique, stress, and early REMD work in animals; REM windows; the processing of declarative versus procedural memory in REM in humans; a mnemonic function for theta rhythm in waking but not in REM sleep; the lack of cognitive deficits in patients on (...) antidepressant drugs that suppress or eliminate REM sleep; the disposition of conscious (dreams) and nonconscious material of REM sleep; and finally our theory of REM sleep. Although our position was strongly challenged, we still hold that REM sleep serves no role in the processing and consolidation of memory. (shrink)

Although considerable attention has been paid to the possible involvement of sleep in memory processing, there is no substantial evidence for it. Walker describes a phenomenon of consolidation-based enhancement (CBE), whereby performance on select procedural tasks improves with overnight sleep; that is, without additional practice on the tasks. CBE, however, appears restricted to a few tasks, and even with these tasks CBE is not confined to sleep but also occurs during wakefulness. Sleep serves no unique role in this process. At (...) best, CBE is a slow, time-dependent process of consolidation that begins with task acquisition in waking and can under some circumstances extend to sleep. (shrink)

George tackles the issues at the heart of the contemporary conflict of worldviews and shows that traditional beliefs may still be the best course of action.

This collection of original papers from distinguished legal theorists offers a challenging assessment of the nature and viability of legal positivism, a branch of legal theory which continues to dominate contemporary legal theoretical debates. To what extent is the law adequately described as autonomous? Should law claim autonomy? These and other questions are addressed by the authors in this carefully edited collection, and it will be of interest to all lawyers and scholars interested in legal philosophy and legal theory.

This work brings together leading defenders of Natural Law and Liberalism for a series of frank and lively exchanges touching upon critical issues of contemporary moral and political theory. The book is an outstanding example of the fruitful engagement of traditions of thought about fundamental matters of ethics and justice.

"Crease’s brilliantly exploited theatrical analogy places scientific theorizing back into the wider context of experimental inquiry." —Robert C. Scharff Crease attacks the "mystical" account of experimentation embraced by the positivist and Kantian varieties of philosophy of science, according to which experimentation takes a backseat to theory.

The Second Creation is a dramatic--and human--chronicle of scientific investigators at the last frontier of knowledge. Robert Crease and Charles Mann take the reader on a fascinating journey in search of "unification" with brilliant scientists such as Niels Bohr, Max Planck, Albert Einstein, Erwin Schrödinger, Richard Feynman, Murray Gell-Mann, Sheldon Glashow, Steven Weinberg, and many others. They provide the definitive and highly entertaining story of the development of modern physics, and the human story of the physicists who set out (...) to find the "theory of everything.". (shrink)

Seven features which in practice seem to differentiate belief systems from knowledge systems are discussed. These are: nonconsensuality, “existence beliefs,” alternative worlds, evaluative components, episodic material, unboundedness, and variable credences. Each of these features gives rise to challenging representation problems. Progress on any of these problems within artificial intelligence would be helpful in the study of knowledge systems as well as belief systems, inasmuch as the distinction between the two types of systems is not absolute.

QBism is an interpretation of quantum mechanics that posits quantum probabilities as subjective Bayesian probabilities, whence its name. By avoiding experientially unfulfilled speculations about what exists prior to measurement, QBism seems to make a close encounter with the phenomenological method. What follows is an interview with QBism’s founder and principal champion, the physicist Christopher Fuchs.

Contemporary liberal thinkers commonly suppose that there is something in principle unjust about the legal prohibition of putatively victimless crimes. Here Robert P. George defends the traditional justification of morals legislation against criticisms advanced by leading liberal theorists. He argues that such legislation can play a legitimate role in maintaining a moral environment conducive to virtue and inhospitable to at least some forms of vice. Among the liberal critics of morals legislation whose views George considers are Ronald Dworkin, Jeremy (...) Waldron, David A.J. Richards, and Joseph Raz. He also considers the influential modern justification for morals legislation offered by Patrick Devlin as an alternative to the traditional approach. George closes with a sketch of a "pluralistic perfectionist" theory of civil liberties and public morality, showing that it is fully compatible with a defense of morals legislation. Making Men Moral will interest legal scholars and political theorists as well as theologians and philosophers focusing on questions of social justice and political morality. (shrink)

The rational choice assumption that any chosen behavior can be understood as optimizing material self?interest is not borne out by psychological research. Expressive motives, for example, are prominent in the symbols of politics, in social relationships, and in the arts of persuasion. Moreover, instrumentality is a mindset that is learned (perhaps overlearned), and can be situationally manipulated; because it is valued in our society, it provides a privileged vocabulary for justifying behaviors that may have been performed for other reasons, and (...) encourages the illusory belief in the universality of rational choice.

John Finnis is a pre-eminent legal, moral and political philosopher. This volume contains over 25 essays by leading international scholars of philosophy and law who critically engage with issues at the heart of Finnis's work.

In this book it is argued that this picture of Feyerabend is false.

This book argues that the primary function of human thinking in language is to make judgments, which are logical-normative connections of concepts. Robert Abele points out that this presupposes cognitive conditions that cannot be accounted for by empirical-linguistic analyses of language content or social conditions alone. Judgments rather assume both reason and a unified subject, and this requires recognition of a Kantian-type of transcendental dimension to them. Judgments are related to perception in that both are syntheses, defined as the (...) unity of representations according to a rule/form. Perceptual syntheses are simultaneously pre-linguistic and proto-rational, and the understanding makes these syntheses conceptually and thus self-consciously explicit. Abele concludes with a transcendental critique of postmodernism and what its deflationary view of ontological categories—such as the unified and reasoning subject—has done to political thinking. He presents an alternative that calls for a return to normativity and a recognition of reason, objectivity, and the universality of principles. (shrink)

Philosophical concerns about nuclear armaments raises questions about the logical and conceptual basis for deterrence theory as well as the effects of nuclear threats on our common humanity. Most philosophical concern centers around around the morality of nuclear deterrence. It is sometimes thought that the doctrine of just war can provide a moral justification for nuclear deterrence based on threats of massive retaliation. Ye attempts to apply the doctrine of just war lead to a moral dilemma: although nuclear deterrence seems (...) justified as self-defense, there are compelling reasons for concluding that threats of retaliation are immoral. Alternative deterrence policies might be thought to overcome the moral dilemma. However, counterforce strategy and anti-missile defense, as recently proposed by President reagan, must still depend upon immoral threats of retaliation. Proposals for a nonviolent national defense offer a possible solution, and serious attention should be given to claims that nonviolent defense is relevant in the nuclear age and would deter aggression.
