This paper provides a memoir and overview of Iris Young's philosophy and a discussion of her account of gender identity.

Although the work of Revonsuo is commendable for its attempt to use an evolutionary approach to formulate a hypothesis about the adaptive function of dreaming, the conclusions arrived at by this author cannot be fully shared. Particularly questionable is the idea that the specific function of dreaming is to simulate threatening events. I propose here a hypothesis in which the dream can have a different function. [Revonsuo].

Conventional wisdom and commonsense morality tend to take the integrity of persons for granted. But for people in systematically unjust societies, self-respect and human dignity may prove to be impossible dreams.Susan Babbitt explores the implications of this insight, arguing that in the face of systemic injustice, individual and social rationality may require the transformation rather than the realization of deep-seated aims, interests, and values. In particular, under such conditions, she argues, the cultivation and ongoing exercise of moral imagination is necessary (...) to discover and defend a more humane social vision. Impossible Dreams is one of those rare books that fruitfully combines discourses that were previously largely separate: feminist and antiracist political theory, analytic ethics and philosophy of mind, and a wide range of non-philosophical literature on the lives of oppressed peoples around the world. It is both an object lesson in reaching across academic barriers and a demonstration of how the best of feminist philosophy can be in conversation with the best of “mainstream” philosophy—as well as affect the lives of real people.

Unlike older sciences such as physics and biology, sociology has never had a revolution. Modern sociology is still classical-largely psychological, teleological, and individualistic-and even less scientific than classical sociology. But pure sociology is different: It predicts and explains the behavior of social life with its location and direction in social space-its geometry. Here I Illustrate pure sociology with formulations about the behavior of ideas, including a theory of scienticity that predicts and explains the degree to which an idea is likely (...) to be scientific (testable, general, simple, valid, and original). For example: Scienticity is a curvilinear function of social distance from the subject. This formulation explains numerous facts about the history and practice of science, such as why some sciences evolved earlier and faster than others and why so much sociology is so unscientific. Because scientific theory is the most scientific science, the theory of scienticity also implies a theory of theory and a methodology for the development of theory. (shrink)

Solms shows the cortical basis for why dreams reflect waking concerns and goals, but with deficient volition. I argue the latter relates to Hobson et al.'s process I as well as M. A memory function for REM sleep is possible, but may be irrelevant to dream characteristics, which, contrary to Revonsuo, mirror the range of waking emotions, positive and negative. [Hobson et al.; Nielsen; Solms; Revonsuo; Vertes & Eastman].

continues to receive many reviews. Judging by recent reviews, this is a very controversial book. The question considered here is, how can one fairly review a controversial book—particularly when the book is widely popular and, for a history of economic thought book, a best seller? This essay uses Mirowski’s book as a case study to propose one answer for this question. In the process, it will examine how others seem to have answered this question. Key Words: methodology • reviews • (...) Mirowski • Machine Dreams. (shrink)

The advent of functional imaging has reinforced the attempts to define dreaming as a sleep state-dependent phenomenon. PET scans revealed major differences between nonREM sleep and REM sleep. However, because dreaming occurs throughout sleep, the common features of the two sleep states, rather than the differences, could help define the prerequisite for the occurrence of dreams. [Hobson et al.; Nielsen; Solms; Revonsuo; Vertes & Eastman].

There are two epistemological problems connected with dreaming, which are of different kinds and require different treatment. The internal problem is best seen as a problem of rational consistency, of how we can maintain all of: Dreams are experiences we have during sleep. Dream-experiences are sufficiently similar to waking experiences for the subject to be able to mistake them for waking experiences. We can tell that we are awake. (1)-(3) threaten to violate a requirement on discrimination: that we can only (...) tell Xs from Ys if there is some detectable difference between Xs and Ys. Attempts to solve the problem by Descartes and Williams are considered. It is suggested that if we take account of levels of epistemic risk, we can use Descartes's criterion of lack of coherence, at least with hindsight - which is the time when we need to use it.

Several Buddhist schools in India, China and Japan concentrate on the interrelationships between waking and dreaming consciousness. In Eastern philosophy, reality can be seen as a dream and an obscure 'reality beyond' can be considered as real. In spite of the overwhelming Platonic-Aristotelian-Freudian influence existent in Western culture, some Western thinkers and artists - Valéry, Baudelaire, and Schnitzler, for example - have been fascinated by a kind of 'simple presence' contained in dreams. I show that this has consequences for a (...) philosophy of space. According to the authors discussed, the dreamer and the player recognize that human space always means the entire cosmos. (shrink)

The virtual annuls all suspension of time that could, through its tragic or stylistic character, confer to time an existential value. This condition is contrasted with time as it functions in dreams. On the grounds of these observations it is shown that there are resemblances between “autistic” symptoms and the virtual world.

This paper is a modified version of my acceptance lecture for the 1986 SPL-Insight Award. It turned into something of a personal credo -describing my view of  the nature of AI  the potential social benefit of applied AI  the importance of basic AI research  the role of logic and the methodology of rational construction  the interplay of applied and basic AI research, and  the importance of funding basic AI. These points are knitted together by (...) an analogy between AI and structural engineering: in particular, between building expert systems and building bridges. (shrink)

The target articles in this volume address the three major questions about dreaming that have been most responsible for the delay in progress in this field over the past 25 years. These are: (1) Where in the brain is dreaming produced, given that dream reports can be elicited from sleep stages other than REM? (2) Do dream plots have any intrinsic meaning? (3) Does dreaming serve some specialized function? The answers offered here when added together support a new model of (...) dreaming that is testable, and should revitalize this area of study. [Hobson et al.; Nielsen; Revonsuo; Solms; Vertes & Eastman]. (shrink)

It has been widely demonstrated that dreaming occurs throughout human sleep. However, we once again are facing new variants of the equation “REM sleep = Dreaming.” Nielsen proposes a model that assumes covert REM processes in NREM sleep. I argue against this possibility, because dream research has shown that REM sleep is not a necessary condition for dreaming to occur. [Nielson].

Dreams were a topic of study even in ancient times, and they are a special spiritual phenomenon. Generations of literati have defined the meaning of dreams in their own way, while Zhu Xi was perhaps the most outstanding one among them. He made profound explanations of dreams from aspects such as the relationship between dreams and the principles li and qi , the relationship between dreams and the state of the heart, and the relationship (...) between dreams and an individual’s moral improvement. He summarized previous generations’ understanding of dreams and infused a new dimension from the School of Principles, pointing out a direction for individuals’ moral cultivation and spiritual pursuit. Zhu Xi also examined the opinions of Zhang Zai, Cheng Yi, Hu Hong and other thinkers on Confucius not dreaming of Duke Zhou in his later years, revealing differences between thinkers in the School of Principles. An analysis of Zhu Xi’s thoughts on dreams will provide deeper insight into the research on the School of Principles. (shrink)

Relatively poor memory for dreams is important evidence for Hobson et al.'s model of conscious states. We describe the time-gap experience as evidence that everyday memory for waking states may not be as good as they assume. As well as being surprisingly sparse, everyday memories may themselves be systematically distorted in the same manner that Revonsuo attributes uniquely to dreams. [Hobson et al.; Revonsuo].

Threat themes are clearly over-represented in dreams. Threat is, however, not the only theme with potential evolutionary significance. Even for hypnagogic and hypnopompic hallucinations during sleep paralysis, for which threat themes are far commoner than for ordinary dreaming, consistent non-threat themes have been reported. Revonsuo's simulation hypothesis represents an encouraging initiative to develop an evolutionary functional approach to dream-related experiences but it could be broadened to include evolutionarily relevant themes beyond threat. It is also suggested that Revonsuo's evolutionary re-interpretation of (...) dreams might profitably be compared to arguments for, and models of, evolutionary functions of play. [Revonsuo]. (shrink)

I have argued that Wittgenstein's treatment of dreaming involves a kind of anti-realism about the past: what makes "I dreamed p " true is, roughly, that I wake with the feeling or impression of having dreamed p . Richard Scheer raises three objections. First, that the texts do not support my interpretation. Second, that the anti-realist view of dreaming does not make sense, so cannot be Wittgenstein's view. Third, that the anti-realist view leaves it a mystery why someone who reports (...) having dreamed such-and-such is inclined to report what she does. The Reply defends my reading of Wittgenstein against these objections. (shrink)

For the anti-realist, the truth about a subject's past thoughts and attitudes is determined by what he is subsequently disposed to judge about them. The argument for an anti-realist interpretation of Wittgenstein's view of past-tense statements seems plausible in three cases: dreams, calculating in the head, and thinking. Wittgenstein is indeed an anti-realist about dreaming. His account of calculating in the head suggests anti-realism about the past, but turns out to be essentially realistic. He does not endorse general anti-realism about (...) past thoughts; but his treatment does in some cases involve elements of anti-realism, unacceptable in some instances but possibly correct in others.

At times of general malaise and social breakdown, it is not uncommon for millenarian movements to arise to replace lost hopes by idle dreams: dreams of a savior who will lead us from bondage, or of the return of the great ships with their bounty, as in the cargo cults of South Sea islanders. Some may yearn for a lost golden age, or succumb to the blandishments of the new Messiahs who come to the fore at such moments. Those more (...) cognizant of the institutional causes of discontent may be attracted to an image of hope destroyed by dark and powerful forces that stole from us the leader who sought a better future. The temptation to seek solace, or salvation, is particularly strong when the means to become engaged in a constructive way in determining one's fate have largely dissolved and disappeared. (shrink)

“The Matrix is a computer-generated dreamworld built to keep us under control” Morpheus, early in The Matrix. “ In dreaming, you are not only out of control, you don’t even know it…I was completely duped again and again the minute my pons, my amygdala, my perihippocampal cortex, my anterior cingulate, my visual association and parietal opercular cortices were revved up and my dorsolateral prefrontal cortex was muffled” ” J. Allan Hobson, The Dream Drugstore, p.64 The Matrix is an exercise in (...) ambivalence, and at the very heart of that ambivalence lies the Dream. In our dreams, we are not in control. Real dreaming, unlike many popular philosophers’ fictions, is an altered state, closely related to the states induced by chemical manipulations such as the use of (certain) medical or recreational drugs. The dreaming brain is not like the wakeful brain. Normal sensory input is blocked, attentional capacities are impaired or lost, memory is distorted, reasoning and logic are weakened, narratives run wild, self-reflection is dampened or destroyed, emotion and instinct are hyperstimulated, and forms of ‘top-down’ willed control and decision-making diluted and easily overwhelmed.

The validity of dream recall is discussed. What is the relation between the actual dream and its later reflection? Nielsen proposes differential sleep mentation, which is probably determined by dream accessibility. Solms argues that REM sleep and dreaming are double dissociable states. Dreaming occurs outside REM sleep when cerebral activation is high enough. That various active sleep states correlate with vivid dream reports implies that REM sleep and dreaming are single dissociable states. Vertes & Eastman reject that REM sleep is (...) involved in memory consolidation. Considerable evidence for this was obtained by REM deprivation studies with the dubious water tank technique.

Dream content is more coherent, consistent over time, and continuous with waking emotional concerns than most brainstem-driven theories of dreaming allow, but dreaming probably has no adaptive function. A new neurocognitive perspective focusing on the forebrain system of dream generation should begin with the findings on dream content in adults and the developmental nature of dreaming in children. [Hobson et al.; Nielsen; Revonsuo; Solms; Vertes & Eastman].

New findings point to a role for mesolimbic DA circuits in the generation of dreaming. We disagree with Solms about these structures having an exclusive role in generating dreams. We review data suggesting that dreaming can be interrupted at different levels of processing and that anterior-subcortical lesions associated with dream cessation are unlikely to produce selective hypodopaminergic dynamic impairments. [Hobson et al.; Nielsen; Solms].

The five papers in this issue all deal with the proper evolutionary function of sleep and dreams, these being different. To establish that some trait of character is an adaptation in the strict biological sense requires a story about the fitness enhancing function it served when it evolved and possibly a story of how the maintenance of this function is fitness enhancing now. My aim is to evaluate the proposals put forward in these papers. My conclusion is that although sleep (...) is almost certainly an adaptation, dreaming is not.

What, if anything, do dreams tell us about ourselves? What is the relationship between types of sleep and types of dreams? Does dreaming serve any purpose? Or are dreams simply meaningless mental noise--"unmusical fingers wandering over the piano keys"? With expertise in philosophy, psychology, and neuroscience, Owen Flanagan is uniquely qualified to answer these questions. In this groundbreaking work, he provides both an accessible survey of the latest research on sleep and dreams and a compelling new theory about the nature (...) and function of dreaming. Flanagan argues that while sleep has a clear biological function and adaptive value, dreams are merely side effects, "free riders," irrelevant from an evolutionary point of view. But dreams are hardly unimportant. Flanagan argues that dreams are self-expressive, the result of our need to find or to create meaning, even when we're sleeping. Written with remarkable insight, Dreaming Souls offers a fascinating new way of apprehending one of the oldest mysteries of mental life. (shrink)

Human beings have the unique ability to consciously reflect on the nature of the self. But reflection has its costs. We can ask what the self is, but as David Hume pointed out, the self, once reflected upon, may be nowhere to be found. The favored view is that we are material beings living in the material world. But if so, a host of destabilizing questions surface. If persons are just a sophisticated sort of animal, then what sense is there (...) to the idea that we are free agents who control our own destinies? What makes the life of any animal, even one as sophisticated as Homo sapiens, worth anything? What place is there in a material world for God? And if there is no place for a God, then what hold can morality possibly have on us--why isn't everything allowed? Flanagan's collection of essays takes on these questions and more. He continues the old philosophical project of reconciling a scientific view of ourselves with a view of ourselves as agents of free will and meaning-makers. But to this project he brings the latest insights of neuroscience, cognitive science, and psychiatry, exploring topics such as whether the conscious mind can be explained scientifically, whether dreams are self-expressive or just noise, the moral socialization of children, and the nature of psychological phenomena such as multiple personality disorder and false memory syndrome. What emerges from these explorations is a liberating vision which can make sense of the self, agency, character transformation, and the value and worth of human life. Flanagan concludes that nothing about a scientific view of persons must lead to nihilism. (shrink)

Both Solms and Nielsen acknowledge the difficulty of accounting for the similarities between REM and NREM sleep mentation with a two-generator model, and each link dreams, either explicitly (Solms) or implicitly (Nielsen), to brain activation. At present, however, no data indicate that brain activation can be demonstrated whenever vivid dream reports are obtained. [Nielsen; Solms].

The Interpretation of Dreams is often thought to be Freud's best book-length work. It was, indeed, Freud's first lengthy statement of a substantially original psychological theory. Freud wrote the book in the late 1890's and published it in 1900; it had a second edition in 1909, and thereafter many subsequent editions. By Freud's own account it was not well received by the scientific..

Nanotechnology is a swiftly developing field of technology that is believed to have the potential of great upsides and excessive downsides. In the ethical debate there has been a strong tendency to strongly focus on either the first or the latter. As a consequence ethical assessments of nanotechnology tend to radically diverge. Optimistic visionaries predict truly utopian states of affairs. Pessimistic thinkers present all manner of apocalyptic visions. Whereas the utopian views follow from one-sidedly focusing on the potential benefits of (...) nanotechnology, the apocalyptic perspectives result from giving exclusive attention to possible worst-case scenarios. These radically opposing evaluations hold the risk of conflicts and unwanted backlashes. Furthermore, many of these drastic views are based on simplified and outdated visions of a nanotechnology dominated by self-replicating assemblers and nanomachines. Hence, the present state of the ethical debate on nanotechnology calls for the development of more balanced and better-informed assessments. As a first step in this direction this contribution presents a new method of framing the ethical debate on nanotechnology. Thus, the focus of this paper is on methodology, not on normative analysis.

There are strong resemblances between the neurobiological characteristics of hallucinations occurring in the particular case of schizophrenia and the hallucinatory activity observed during the rapid-eye-movement (dreaming) sleep stage: the same prefrontal dorsolateral deactivation; forebrain disconnectivity and disinhibition; sensory deprivation; and acetylcholine, monoamine, and glutamate modifications.
