Book Description InBioethics in America, Tina Stevens challenges the view that the origins of the bioethics movement can be found in the 1960s, a decade mounting challenges to all variety of authority. Instead, Stevens sees bioethics as one more product of a "centuries-long cultural legacy of American ambivalence toward progress," and she finds its modern roots in the responsible science movement that emerged following detonation of the atomic bomb. Rather than challenging authority, she says, the bioethics movement was an aid to authority, in that it allowed medical doctors and researchers to proceed on course while bioethicists managed public fears about medicine's new technologies. That is, the public was reassured by bioethical oversight of biomedicine; in reality, however, bioethicists belonged to the same mainstream that produced the doctors and researchers whom the bioethicists were guiding. | |

Book Description Our Molecular Future reveals a striking new possibility: We are on the verge of being able to protect ourselves from natures worst attacks. Tools such as carbon nanotubes may help us cope in ways that until now have been described as science fiction. If we succeed, we might solve a troubling question about scientific research: Why risk it? Why risk powerful new technologies that may destroy us? With compelling evidence, Douglas Mulhall shows that the answers to such questions may be found by focusing on what the environment does to us, rather than only what we do to the environment. His book shows where our technologies might be heading, what may stop us from getting there, and how to use the benefits to minimize the downsides. The good news is that we may enter a future that's so fantastic, it's unbelievable. The bad news is that many of us don't believe it, and so we may not be ready to cope. By revealing the threads that tie our fate to new technologies, this book helps us get ready. First, we have to ask the right questions. Mulhall emphasizes that this book defines those questions, rather than pretending to have quick or detailed answers. Here are examples: Molecular technologies arent just confined to a few university think tanks. Nor are they confined to an elite among the superpowers, big business, or government. Their roots are embedded in the fabric of our industries, research institutes, and military. They are found in wealthy and poor nations alike. The foundations for these technologies are so pervasive that its hard to describe them without starting an encyclopedia. Our Molecular Future condenses this knowledge and gives us broad overviews of whos doing what, where. By so doing, the book shows us why these technologies pose such deep challenges to conventional thinking about business and environment. Yet, how vulnerable is this technological juggernaut to being thrown backward or blasted down the wrong path by natures violent attacks? In ninety seconds, the Great Kanto Earthquake annihilated Japans centralized economy in 1923. It was so severe that the country was in no shape to weather the Great Depression. Such instability helped open the door for a military government. After the military took over, war in Southeast Asiaand then the Pacificbroke out. Might this recur today? What about similar such risks in America? What if the largest earthquake in Americas history was to hit again? Surprisingly, it didnt occur in San Francisco, or on the quake-prone West Coast. Our Molecular Future reveals the location and the implications. Property loss is increasing worldwide, due to unrestricted development in risky hurricane and earthquake zones. Perversely, this can actually improve economic conditions for some sectors in the short term, by fueling construction booms after disasters. Such short-term rebounds are often generated by insurance settlements. Yet underneath, a cancer grows. This foundation for economic stabilityinsuranceis collapsing. Our Molecular Future reveals the depth of the situation. To inoculate ourselves against natures occasional tantrums, and avoid collapse of the insurance industry, we may have to construct powerful molecular defenses. Yet, these defenses themselves may threaten our existence, due to their potential for abuse. Some say that the risks outweigh the potential gains. So, if its such a risk, why go there? Evidence suggests there may be no alternative. Our Molecular Future explains why. By tracing disruptions of the past and advances of the present through to technologies of the future, it becomes more than a book: it's a whole new field of study; a multifaceted approach to our past, our present, and our potential futures. Because of this, the book appeals to a wide range of readers. Read it if you are... ...striving to understand the molecular world that we may soon live in ...wondering about your job prospects or health care in an age of disruptive technologies ...looking for ways to cope with climate extremes or natural disasters The book also has special relevance if youre one of these individuals: A business or economics student: Here are ideas about what startups might flourish in a molecular economy. "Genetic computing" may make most manufacturing processes and patents obsolete.Moreover, new industries might emerge from our capacities to cope with natural hazards. A lecturer or student in environment, natural science, and ethics. The book is a valuable supplement to course materials: --For environment, it identifies challenges to the Precautionary Principle and the doctrine of sustainable development. --For natural science, it summarizes new discoveries about naturally occurring climate changes and ecological disruptions that are changing our views about the stability of the natural world. --For scientific ethics, it gives an overview of the ethical questions associated with development of powerful new tools. An executive positioning your company for the approaching molecular era. Here is information about startups that might flourish in a molecular economy. An insurer or corporate manager who plans disaster recovery strategies. This summarizes natural risks and technologies that may alter the way that businesses prepare for them. A health care provider. Research into nanobacteria and robotic surgery may alter the way we treat disease. A scientist confronted by environmental opposition to your technologies: Here's one way out of the impasse between the life sciences and environmentalists. An environmentalist who forecasts how technology might alter the ecology: Molecular technologies and natural changes may upend the Precautionary Principle and the doctrine of sustainable development. The book also has an extensive index and endnotes, with links to authoritative Web sites. Reviews (4)
The author has done his research and has a large source of information to draw from. This book gives the reader a good overview of real scientific advancements as well as other insights from prominent leaders and theorists in these fields. There are ample notes and anecdotes to give the reader the option to pursue more detailed information on the topics. A few parts of the book drag due to some repetitiveness and some of the discussions don't appear to have a firm scientific base and don't seem too plausible, especially if you have decent scientific knowledge in the particular subject. If you are a scientist or engineer with some expertise in the fields you may find that some theories lack a firm foundation. However one theme that comes with the author's optimism is that throughout history, even the most prominent experts have been proven wrong through natural progressions and even breakthroughs! This work is not incredibly deep or profound though quite entertaining and at times it appears to feel more like a novel than a documentary of the future. It is suitable for readers of all walks of life.
The author asks us to imagine a conversation between a farmer in the year 1899 and a person who rolls up in an early automobile. The driver tells the farmer what is ahead in the next decades, such as playing golf on the moon, his children being able to drive themselves faster than a locomotive, his cows milked using machines, etc. The author then replays the same conversation but with a farmer of the year 2001, he automobile is replaced by a flying car: golf will be played on Mars, and egg hatcheries will be designed by computers that do a better job then humans, agriculture will be replaced by food synthesizers, etc. With these hypothetical conversations, the author asks us to take stock in our skepticism that the future he outlines in the book it too far-fetched. In addition, human factors engineering, which is not really emphasized in the book, may determine the outcome of particular technologies. Voice recognition and command in computers for example, may be too annoying to actually employ in the workplace, if open cubicle environments are still in place. The resulting noise level of everyone talking to their computers might be too irritating. Federal and state health requirements also have a repressive influence on the employing of new technology. With the growing hostility towards genetic engineering, governments will be stepping up their regulations and this might dampen the ever-growing amplitude of 21st century development. The author is aware of these attitudes towards technology, and so he attempts to offer a different sort of justification for employing them, particularly nanotechnology. Much space in the book is devoted to the use of this to combat natural disasters, such as asteroids, earthquakes, tornadoes, tsunamies, and radical climate changes. Many of his proposals for using nanotechnology to do this are interesting, such as "utility fog", which allows material objects to change shape at arbitrary time scales, food fabrication using molecular biosynthesis and robotic replenishment, and the intelligent product system (IPS), which allows maximal compatibility with the environment. In addition, the author envisions the deployment of millions of nanosatellites that will probe the solar system in order to find rogue asteroids that threaten our planet. Once found, the asteroid will be dissassembled layer by layer to a size that nullifies its threat. The residue will then be used as raw materials for space-based colonies. The author is also realistic in his appraisal of just what it is going to take from a financial perspective to develop the technology which he envisions. Such developments can be accomplished, and the financial and time scales involved, coupled with the physical dimensions of the technology, are the justification for his optimism. He does not use "inevitability" arguments to justify future technology developments, but instead realizes, correctly, that such developments are subject to human volition. We can halt or move forward, the choice being completely our own. Robo sapiens, Robo servers, and Homo provectus, may be on the way the author states. He asks us if we are ready, and he asks us to consider the answers to the employment of new technologies ourselves, and not leave it up to our government or religious leaders, who themselves are explaining it to us inadequately, he argues. Religious institutions are centuries behind, companies are selling products and services but are not structured to serve our interests, and scientists are too involved in their projects to consider how their discoveries will impact human life on Earth. The author encourages the reader to get involved, or invent, institutions or strategies that will mesh with the technological advances that are confronting each one of us. I cannot speak for the author here, but he seems to be incredibly optimisitic. This is refreshing, for this indeed is the most exciting time to be alive. We should all constantly attempt to improve ourselves and others with the knowledge we have available. With genetic engineering, artificial intelligence, highly sophisticated mathematics, robotics, and nanotechnology, we have precisely the right instruments, at precisely the right time, to participate in and build the greatest century yet for the human species...

Focus is on intuition and global understanding, not on mathematical aspects. However, some knowledge in math would certainly help...a first course in probability theory and some background in dynamical systems is a good idea (at the level of undergraduate courses in pure and applied sciences). All explanations are not rigorous but the objective is to provide a good intuition about the mechanisms driving complexity. Recommended for all people interested in stochastic modeling and chaos theory.

Their stated reason for adapting this biased perspective is that the opposite view (that Hobbes was wrong) has been so thoroughly documented that not much new could be added. Only by adopting a "charitable" view of Hobbes, and a critical view of his opponents, could they make a significant new contribution. In other words, they wanted to make a splash, not a ripple. Their bias is expressed by selective omission of information unfavorable to Hobbes. For example, in Hobbes's "Dialogus Physicus", his fallacious solution of the cube-duplication problem has been deleted, without mentioning that it was fallacious. Also, the reader is not informed that a "Torricelli apparatus" and a "mercury barometer" are functionally identical; the height of the mercury column varies with weather conditions. This variability was a problem for Hobbes, but not for Boyle. But it is not mentioned, except in connection with a suggestion that the experimentalists may have fudged their data. Also, the authors should have noted that Hobbes's a-priori rationalist philosophy is not a viable alternative to experimentalism, because it is based on an elementary logical fallacy: you cannot make up definitions and postulates arbitrarily AND claim that deductions from them give certainty about the real world. ...

Ruse establishes his credentials promptly, offering a succinct account of "Darwinism" [a term i loathe]. He explains the history and mechanisms of evolution by natural selection with aplomb. The book is valuable for this summation, if nothing else. He explains various forms of evidence such as the similarity of animal body structures [homology]. He continues with various dialogues between Christians who view evolution as a threat to morals, society, ethics and the other tired arguments and why they have no basis. Finally, Ruse states the obvious: many scientists are and have been, successfully practicing Christians. Whether or not they've made the effort to rationalise this disparity, he saves them the effort in examining how the reconciliation can be achieved. For centuries, he reminds us, the study of Nature was in order to glorify a deity. He uses Augustine frequently in support of the view that Nature deserves serious study. Ruse calls this "the Augustinian option", that Christianity has no room for the ignorant. Nature's wonders and laws follow a divine plan, which must be recognized and respected. Science then, is not an enemy, but rather an ally. Ruse concludes with a firm "Absolutely!" to the book's title. He warns of the difficulties: one must choose from among the various Christian ethics and values, recognize that not all questions have been answered nor all issues resolved, be prepared for some in-depth study. The path is difficult, but having been traversed by some, others may follow. Given the nature of the topic, Ruse has performed an outstanding service in addressing this complex question with such finesse and clarity. [stephen a. haines - Ottawa, Canada]
This is just one possibility that I don't think was properly explored, and ultimately no viable option is presented. I'd recommend Kenneth Miller's "Finding Darwin's God" as a much more informative source, a book that actually provides answers and has the courage to challenge longstanding theories and theorists. ...

Pere Teilhard's system focuses on the Omega point as the point of convergence for all evolution and all space-time. This is really missing from O'Murchu, since his universe never really gets to Omega.
It is difficult reading, but well worth the effort. I find myself looking at the universe and life from a new and refreshing perspective. Randy Herring's review must have been written by an intellectual show-off. One of the major premises of the book is not how one deals with the world, but rather, how the world deals with us. Our control is imaginary and our understanding ridiculously lacking, and that was one of O'Murchu's major points.
O'Murchu fails to define what he means by 'matrix.' Thus, arises O'Murchu's three gravest flaws: 1) failing to define 'matrix,' 2) failing by assuming one knows what the conventional definition of 'matrix' entails, and 3) failing to clarify his meaning of intentionality, except within his symbolism of "Divine relationality." O'Murchu stupidly leaves the definition of 'matrix' open-ended, which allows the reader to pursue for further investigation. A 'matrix,' to this reviewer, is a system and a closure that "out of the womb within" encircles the relationality of the development of a "stereotype!" Words develop with a purpose: for use and relationality. It is out of the womb that one sees things from within one's own perimeters, i.e., a system, a closure of how one "deals" with the world. O'Murchu's "relational matrix" adds to the "great deal of baggage" that he admonishes we ought "to shed!" If evolutionary faith is faith directed by the drive of evolutionary process of 'becoming' then a matrix makes evolutionary faith incapable of possessing that drive of intoxicating energy for becoming. Without a matrix, one's consciousness is strong because it is free from any kind of relational comparison, and thus, extols one's capacity and need for communication relating with others! The weakness of consciousness vis-à-vis a matrix only increases the greatest weight of nihilistic "globalization" that O'Murchu opposes. Thus, the "archetype" (below) of a "new cosmology" to thwart the furtherance of "globalization" is of no consequence. O'Murchu carries more baggage (his greatest trouble) than he can handle (his greatest weight). Contrary to his own intentions O'Murchu posits his antithesis: another form of "globalization" masked by "evolutionary faith." The "relational matrix" is "globalization" because both are systems of oppression of adding to the baggage O'Murchu admits he does not want. O'Murchu's relational matrix does not come full circle of embracing the mysticism of a "new cosmology" and thus, does not toss "globalization" to the wayside. O'Murchu crushes under his own weight trying to convince us he seeks to eradicate the dualistic religion and science futuristic tendencies of "gloom and doom." It is in fact the same tendencies he embraces by introducing his "new cosmology" of light as an "archetype" that opposes the "globalization" of darkness, that is, the recurrence of the same dualistic notion of good versus evil! O'Murchu is more religious and Christian he gives himself credit for. Thus Spoke O'Murchu! O'Murchu digs his own crevasse, falls into it and becomes wedged in his story of evolutionary faith. O'Murchu brings man down with his own god and goes under himself! This 'O'Murchu event' triggers a cataclysmic recurrence of the same yet to be reconciled under its own crushing weight (the "great story"). O'Murchu leaves us confronted with a yet undiscovered country whose boundaries nobody has surveyed. It is an undiscovered country beyond all the lands and nooks of Thus Spoke O'Murchu. It is a world so overrich in what is beautiful, strange, questionable, terrible, and divine. The "new cosmology" is more daring perhaps than is prudent. Thus, O'Murchu's greatest weight of recurrence is turned upside down repeatedly in the same succession and sequence. O'Murchu desires nothing new but every pain and every joy and every thought to add to the greatest trouble in reconciling the greatest weight with the "great story" he calls evolutionary faith. Thus Spoke O'Murchu! ... Read more | |

All in all, a small, but very clear and important critical book.
Searle's merciless criticisms of recent approaches to consciousness are based on his own original viewpoint proposed in his books Minds, Brains, and Science (1984) and The Rediscovery of the Mind (1992). According to Searle, consciousness is both an irreducibly subjective mental phenomenon and a biological feature of the brain. Searle compares consciousness to digestion in the stomach or the sharpness of a pain, higher-level features of physical structures which are at the same time caused by lower-level micro-features of these structures. The mind/body problem is solved when we repudiate the dogmatic assumption that all properties are exclusively mental or physical. This forced dichotomy has led many philosophers to advocate either dualism, where the mental and the physical are separate phenomena, or materialism, where the mental gets completely eliminated in favor of the physical. Dualism leads to the insoluble problem of mind/body interaction, while materialism ignores the simple fact that we are conscious (most of the time, at any rate), and that consciousness "is the condition that makes it possible for anything to matter to anybody." (xiv) By countenancing consciousness as both mental and physical, Searle delivers us out of this problematic. As a mental phenomenon, consciousness is an irreducible property which is given to us in moments of sentient awareness; and as a biological property, we can (in principle) explain consciousness in terms of the methods of the natural sciences. From this vantage point, any view that posits a form of materialism or dualism will be accused of conceptual confusion, a failure to see that the "mental" need not stand in opposition to the "physical." Thus Searle is led to dismiss the views of Chalmers (the property dualist) and Dennett (the materalist) without much difficulty. However, Searle's dismissive approach fails to appreciate that these views advance powerful arguments against Searle's own precarious double-aspect view. Take Chalmers' argument first. Chalmers argues that there is a logically possible zombie world physically identical to our own but without any conscious properties. If so, then the conscious facts that obtain in the actual world cannot be logically deduced from the physical facts. As Chalmers concludes, "facts about consciousness are further facts about our world, over and above the physical facts." Searle objects that the argument is question-begging, since it presupposes that an absence of consciousness would not logically entail a change in the physical features of the world. There is a logically possible world where pigs fly, but that would entail a change in the physical facts. Similarly, Searle argues, there is a logically possible world where there is no consciousness, but if consciousness is a physical feature of the world, such a world would require a change in the physical facts. Thus Chalmers' argument only works if he assumes that consciousness is non-physical, which is the very point he is supposed to prove. Both Chalmers and Searle agree that biological facts are logically supervenient on the physical facts, so that a world which contained the same physical facts would logically entail the same biological facts. Since consciousness is a biological fact, for Searle, he concludes that the physical facts logically entail the conscious facts. Chalmers, however, initially takes it to be an open question whether consciousness is a biological fact; the point of the thought-experiment is to show that there is an important difference between consciousness and biological facts. For we cannot imagine a world physically identical to ours but where no digestion occurs; given identical physical processes in the stomach, digestion must occur in this world as a logical consequence. As Chalmers puts it, "even God could not have created a world that was physically identical to ours but biologically distinct." However, we can imagine a world which is physically identical to ours but where there is no consciousness. Insofar as such a world is coherent, Chalmers is not begging the question by assuming that consciousness is non-physical. For the whole point of the thought-experiment is to demonstrate a disanalogy between consciousness and physical properties. It is clear that it is Searle who is begging the question by just assuming that consciousness is a physical/biological fact and then plugging his ears to Chalmers' thought-experiment based on this assumption. ...[edited for length] It seems that, no matter what neurophysiological processes are offerred as explanations for co
I think that argument, by the way, while superficially right and useful (as a corrective to those with an overly mechanistic view of mind), ultimately misses the point because Searle presents it as a denial of what he calls "Strong Artificial Intelligence," the position that holds one can build minds, with the sort of consciousness we have, on computers using programs to accomplish this. Relying on the Chinese Room argument, Searle denies "Strong AI" by noting that programs are purely formal, or syntactical as he puts it, and that syntax cannot give meaning which requires a knowing, thinking, aware subject. The problem with his argument is that the Chinese Room thought experiment -- while demonstrating that we do expect to see a knower at work in acts of "intelligence" (and that computers as presented in his thought experiment do not and cannot know anything) -- still does not demonstrate that computers that have been configured and programmed in certain ways cannot produce, at a "higher" level, just what he wants to deny them, consciousness. That is, syntax may indeed yield semantics in the same way that Searle tells us, elsewhere, that atomic structure can yield hardness or liquidness. But Searle seems never to notice this fundamental flaw in his case. Searle remains fixated on his idea that consciousness is somehow not explainable via syntactical operations, as seen in computers, and this position keeps cropping up in criticisms of the various writers under review in this book. He's particularly hard on Daniel Dennett (Consciousness Explained), whom he takes to task for suggesting we are all zombie-like and so, says Searle, seems to be denying the qualitative nature of consciousness which the Chinese Room argument demonstrates. Of course, one can read Dennett's claim as being somewhat polemical since it is hard to take Dennett as saying there is no consciousness in the sense that neither he nor the rest of us have it. Dennett's point seems, rather, to be that consciousness is explainable in terms of non-conscious building blocks and that the sense of being a conscious entity that we get is only that, a sense of this. In fact, Dennett wants to tell us there is no entity per se, only various brain functionalities which combine in certain ways to build the subjectness that we experience as consciousness. But Searle, taking Dennett literally, accuses him of actually arguing that we are all zombies, i.e., unconcious except that we happen to think we're conscious! Such a reading is, of course, a contradiction in terms as Searle suggests. But this does not seem to be a fair interpretation of Dennett's claims. Searle's Chinese Room argument is right insofar as it shows that the idea of "intelligence" (what we mean by intelligence in creatures like ourselves) requires a subjective knower. But it is wrong insofar as Searle wants to say that it thereby demonstrates why a claim like the one Dennett makes, that consciousness can be built up on a non-organic machine platform (e.g., computers and their programs), is, itself, wrong. In fact, Dennett's claim looks better and better against the weaknesses of the Chinese Room argument when this argument is applied as an attack against "Strong AI" as Searle uses it. Searle also takes on David Chalmers (The Conscious Mind: In Search of a Fundamental Theory) and attacks him for suggesting that consciousness is something that is, in principle, logically divorced from the physicality of the world. As it happens, Chalmers has offered a very useful analysis of the uses we make of mental terms in many cases, showing how we often have two things in mind: a reference to the operational aspects and a reference to the phenomenality that often accompanies the operational aspects, i.e., our experience of having experiences, our subjectness. That we often mean both or one or the other in different contexts seems, in fact, to be quite true. And Chalmers also seems to be right in noting that we often have trouble distinguishing what exactly we are referring to in many actual cases and that the referral function tends to slip and slide over this somewhat icy sheet. However, Searle rightly suggests that while this may be true of our usages, it doesn't mean that mind and body are two parallel realms as Chalmers seems to be proposing. For Searle this is a matter of how we talk about the phenomena of our experience, i.e., that minds are the functions of brains just as digestion is the function of stomachs, pumping blood is the function of hearts, etc. But Searle thinks Chalmers falls into property dualism while suggesting, simultaneously, that consciousness is irreducible. Searle's position is that it is, indeed, irreducible in terms of levels of speech, but scientifically, he wants to say that we can certainly reduce it to a biological function of brains which, as yet, is beyond our understanding but not, perhaps, forever. Searle thinks that Chalmers holds a position which could, in principle, suppose that consciousness exists throughout the universe at every level, inanimate as well as animate. Though Chalmers' rebuttal to this reading is included in the book, Searle does not accept the rebuttal as written and insists the conclusion remains implied in Chalmers' arguments. Searle addresses other writers here as well, including Edelman's work on massively redundant brain processing which he finds quite promising, etc. Because of the limitation of this amazon review format, I can't go much further. But suffice it to say, this is a good book and a useful introduction to the ideas of these thinkers. Searle is a good expositor and has some useful points to make, though I think, in the end, that he has got some things quite wrong, particularly his claim that his Chinese Room argument puts paid to the notion of "Strong AI" which, he tells us, holds that minds can be built out of computers and their programs. His failure to see the weakness in this core claim of his in the end undermines the strength of his criticisms of the other writers presented here.
In this book, Searle discusses and critiques the work of a number of theorists and makes numerous observations related to these points, and I thought I'd add a few more. So I'll just make a few observations about the neuroscience for the road, since that's my specialty, including some interesting work related to the clinical side, since some of it is quite fascinating (especially the "orgasmotronic people" I discuss at the end). :-) The first area I'd like to discuss relates to the area of emotions and specifically mood disorders, which has focused on the neurochemical and serotonin and dopaminergic issues, especially since these chemicals have a profound influence on the limbic system areas and the areas they connect with, such as the temporal, frontal, and prefrontal cortex. The limbic system is an older area of the mammalian brain that has profound effects on emotional behavior and many aspects of personality. It is well established that chemical imbalances and/or damage, such as through trauma and stroke and so on, can cause various syndromes, ranging from mood and emotional disorders to cognitive deficiencies. We still have a lot to learn about this, but the basic chemical pathways have been worked out. For example, deficits in long-term motivation (which many people have) have been found to be associated with the nerve pathways connecting the prefrontal cortex and the limbic system. Another avenue of research that looks promising relates to schizophrenia, which is that what we call "consciousness" actually results from the integration of separate and diverse brain areas acting in concert, and that when this integration becomes impaired, there are problems. Of course, it remains to be seen if can be treated some way, but again, our understanding of the possible mechanism is continuing to progress. Another example of how our emotional life depends on the brain is the finding that 70% of death-row inmates have been found to have abnormal EEGs and brain waves emanating from the amygdala, another important structure in the limbic system. The amygdala is involved in aggressive and even homicidal behavior. In one famous case, a formerly quiet, unassuming man developed an amygdalar tumor and shot 17 people and wounded 30 others before he was stopped. There are now drugs that treat abnormal electrical activity in the brain, and the hope is that someday they may even be able to detect and prevent situations like this. For another fascinating example, take homosexuality, which many people still think is a form of psychopathology. Freud said it was because the boy didn't have a strong father figure, and so doesn't know better. For years homosexuals were treated with psychoanalysis with no effect. Then about 20 years ago, a scientist at Caltech made the amazing discovery that heterosexuals and homosexuals had different neurochemical and anatomical characteristics in one of the limbic areas known as the neurosecretory zone of the preoptic hypothalamic nucleus. In fact, he was able to get animals to display either heterosexual or homosexual behavior by diffusing neurosynaptic chemicals into the preoptic area. So much for the Freudian theory. This research proves that this aspect of our behavior is due entirely to how are brains are wired from birth, and has nothing to do with old notions of psychopathology. One of the most fascinating cases I came across was a number of people who had been perfectly normal, but had recently become almost complete "vegetables" and had to be hospitalized. At least so they seemed on the surface. There was nothing wrong with them cognitively, they still had normal reasoning ability and could talk and socialize if they wanted to. They just had no interest in it. They progressively lost interest in their famlies, jobs, friends, everything, and eventually had to be hospitalized. It was discovered that these people had developed an epileptic seizure focus in the orgasm center in the brain. If I remember right, it had the tongue-twisting name of the nucleus reticularis gigantocellularis. In any case, it was in one of the somatosensory processing areas in the thalamus, which is a structure just below the cortex but above the limbic system. Although this is technically a form of epilepsy, there are no convulsions associated with this syndrome (just as there aren't in the case of temporal-lobe epilepsy, which, since it occurs in the memory and associational area of the brain, can produce intense visions and memories, as well as emotional states). Now it was obvious why these people weren't interested in anything else in their lives. They had orgasms that went on for several minutes, and due to the intensity of the electrical discharge, were probably 10 to 100 times as intense as a normal person's orgasms. And they kept having them. Especially the women patients said it was better than anything they could experience before. So they just sat there, waiting, yearning, hoping, for that next "seizure." Anyway, just a few more interesting things to consider relating to our knowledge of the mind and brain. The above facts amply illustrate and further support Searle's theory that the mind is a function of the brain and that the classical mind/brain dichotomy is false.

Amazon.com Marked by Feynman's characteristic combination of rationality and humor, these lectures provide an intimate glimpse at the man behind the legend."In case you are beginning to believe," he says at the start of his final lecture, "that some of the things I said before are true because I am a scientist and according to the brochure that you get I won some awards and so forth, instead of your looking at the ideas themselves and judging them directly...I will get rid of that tonight. I dedicate this lecture to showing what ridiculous conclusions and rare statements such a man as myself can make." Rare, perhaps. Irreverent, sure. But ridiculous? Not even close. Reviews (36)
I have to be honest to admit that I can barely read most of his scientific work. I'm just not that smart.But he was also humorous and wise and this book is more about his general belief system and other matters. Even his prose is not easy reading. His sentences are so long and complex and so well-constructed that the reader feels like he's swimming on the surface of the deepest part of the ocean.Whole lectures feel perfectly designed and complete, all in a curious, Woody Allen, Jewish persona. I actually believe and follow his worldview, which was roughly analagous to Einstein's. They were Secular Humanists.They believed that God if he exists, only manifests in a very distant, abstract sense. Both were loathe to accept specific religious views. It is Feynman's view that science rejects the type of absolute certainty at the core of most mainstream religious views of the world.Interestingly, he includes Soviet Communism as a type of religion, which is understandable when you think about it. Much of this book is really about the intersection of science and philosophy. He asks: how do we justify right and wrong and other human standards in a world without such a self-invented reward-and-punishment system. This is surely one of the questions for the ages, one that Feynman clearly believes is beyond the inherent limits of the scientific worldview.He believed that the flaw was inherent in human makeup, and that the solution was also there - not in the science but in the application. His example was: why is there no water system in the slums of Rio?The money to improve people's lives is there.The will to action is not. Both Feynman and Einstein considered capitalism a necessary but untrustworthy system, and had political leanings toward the Left. Feynman discusses the serious responsibilities involved with science, which has in the 20th century been the Pandora's box, bringing enormous forces and power into the world for either good or abuse or evil. He puts forward perhaps 6 absolute truths that allow for improved human interaction and the greater good of mankind.Most are obliquely political in nature, democracy, freedom of speech, separation of science from exterior interests or intervention, the value of uncertainty, But in the end, his combined belief system is unclear. It lacks something that the human spirit requires for complete fulfillment.He fully recognized this and I don't fault him for it. The paradox he attempts to address are inherent in the basic fabric of the world, and if he did think that he knew the answers he would be a different animal altogether. Considering the direction the nation has taken these last few years, his voice is sorely missed.

Book Description The authors argue that changes in society now make such communications both more likely and more numerous, and that this is transforming science not only in its research practices and the institutions that support it but also deep in its epistemological core. To explain these changes, Nowotny, Scott and Gibbons have developed an open, dynamic framework for re-thinking science. The authors conclude that the line which formerly demarcated society from science is regularly transgressed and that the resulting closer interaction of science and society signals the emergence of a new kind of science: contextualized or context-sensitive science. The co-evolution between society and science requires a more or less complete re-thinking of the basis on which a new social contract between science and society might be constructed. In their discussion the authors present some of the elements that would comprise this new social contract. Reviews (1)
The book is written in the genre of the grand, unspecific sweep. There are few references and few concrete examples. The crude before-and-after discourse is heuristically useful but of course in many ways misleading. These stylistic choices are not everyone's cup of tea, but they do help making the above argument. ... Read more | |

Entertaining bored programmers is not, of course, the primary focus of the book, but it alone makes the book worth buying.

I used this text and Refuting Evolution once in a course I teach that examines the creationism/evolution public education controversy. With so much of Sarfati's over-simplification of issues and claims regarding evidence, most college students roll their eyes after 5 minutes with the text and none have viewed any of the explanations the author puts forth as even remotely plausible or worth their consideration. The only observation that students consistently point out is the fanatic nature | |
