Green's careful, balanced analysis of indigenous theories of contagious disease is an antidote for ignorance. His book represents a crucial first step toward abandoning inter-cultural and professional prejudices that hinder best practices in healing, wellness, and community health. He argues that popularized theories of disease causation in Africa, including witchcraft, sorcery ,and magic, have fostered a "myth of excessive supernaturalism." This myth has evolved with little reference to ethnographic facts and is part of the belief system of Western-educated anthropologists and medical professionals. Acceptance of this particular "story" of disease causation has helped entrench a theoretically unsound basis for biomedical praxis in multicultural settings. Green asserts that indigenous African etiologic models reflect a high prevalence of ideas about naturalisitic and impersonal causes, much of which is linked to contagion and pollution. The models and evidence he discovered do not support the notion that supernatural forces reign paramount in African disease frameworks. Instead, Africans emphasize naturalistic and impersonal causes of illness, rather than human agency and unseen forces.
Green's aims to create a more balanced view of ethnomedicine and to make the case for an Indigenous Contagion Theory (ICT). This, he believes, can help to foster mutual awareness of common ground shared by the two systems. The etiologic overlap holds promise as a basis for cooperation between biomedicine and traditional healers.
Early chapters review a broad spectrum of African health beliefs and etiologies, Bantu ideas about pollution and other forms of contagion, and the relationship of disease resistance and the internal snake/equilibrium concept. These are followed mid-book by essays about notions of contagion in childhood diarrhea, STDs and AIDS (arguably the finest chapter) , and infectious diseases such as malaria, TB, Bilharzia, epilepsy, and other syndromes identified with specific ethnic groups in southern Africa.
In the penultimate chapter, Green places ICT in a broader, even global perspective and asks: "Does it matter if illness is thought of in natural or personalistic terms" (p. 217)? He connects this question to the issue of fostering a change in outlook and practice among health professionals who have carried "a negative, dismissive, etic mind-set." Green seeks common ground, identifying the elements of African ICT (naturalistic infection, mystical contagion (pollution), environmental hazards, and illness from taboo violations). He argues persuasively that public health initiatives will be more effective if those who design and implement them have "an empirically based understanding of existing ethnomedical beliefs" (pp. 217-18). In "Theoretical Implications," the final chapter, Green cites "archaic templates of contagion" as a basis for interpreting the similarity of models of contagious illnesses among Bantu societies. There is extensive discussion of hypotheses about and critiques of adaptive models of health beliefs.
Biomedicine has never, anywhere, at any time, been poured into "empty vessels." This is unfortunate myth is sustained by the professionalization of health care and biomedicine's presumed omnipotence. Further, there is the corollary that scientific medicine cannot be reconciled with indigenous therapy because the latter is believed to be too heavily invested in human agency and the supernatural. In Africa this has led to a situation in which doctors and clinical assistants, nurses and public health professionals, and Ministry of Health officials and international agencies operate in a landscape of de facto medical and public health "apartheid." Whereas biomedical resources remain thin, there is little reliable, useful information in circulation about the indigenous systems that serve the majority of the population. The latter are usually assumed to be either dangerous or irrelevant. Meanwhile, it remains well-established that most people do not choose between indigenous or modern practitioners, but rather seek help across the range of available alternatives for particular conditions. Professional myopia concerning the nature and health implications of this behavior inhibits good health care, prevention, and promotion. Green's effort to dig up the facts and stimulate professional action could lead to measurable benefits for the clients of the various indigenous and biomedical healing professions.
Green's case for ICT is compelling. This reviewer also believes that naturalistic and impersonal disease causation has long been underestimated. Also, few developments promise more positive health results than sustainable collaboration between traditional healers and biomedical sector. Yet, one cautions against allowing the pendulum of causation to swing so far as to unduly minimize supernatural and personalistic interpretations. Fieldwork by this reviewer in Kenya among rural and urban Akamba healers revealed, two decades ago, that 98 percent ranked 'God-given'/natural causes first. Yet witchcraft was the second most common cause of illness, reported by 86 percent of the healers. Not all diseases have mutually exclusive causes. Circumstances may allow for a naturalistic interpretation in one episode and a personalistic (witchcraft) explanation at another time or with a different patient. Furthermore, both interpretations may apply. Today, few Africans remain unaware that STDs and HIV primarily spread through sexual contact. However, human agency--manifested as a desire to send a harmful "message" to someone--may be the ultimate explanation of why the virus victimized a particular person.
Green writes well and provides a high standard of scholarship. The book should deservedly enjoy a broad readership among health workers, social scientists, and those in a position to influence health policies. (Adapted from C. Good, J. of Alternative and Complementary Medicine (2000).
His thoughtful, measured analysis of ITC and its implications for public health arrives as a long-awaited and crucial response to the all-too-frequent dismissal of -- if not downright opposition to -- indigenous healing practices and belief systems on the part of foreign aid workers, development "experts" and often even by Western-educated nationals of African and other developing regions. Green's creative ideas for integrating ITC with biomedicine are of paramount and timely importance towards addressing a number of today's health plagues, from AIDS to TB, malaria and a host of other contagious scourges. As he reasons, "We do no injustice to science and medicine, and certainly not to public health, if we build on - rather than ignore or confront - indigenous contagion beliefs in our attempts to mitigate the ravages of infectious diseases" (p. 18).
The author clearly strives to avoid either/or polarizations in his analysis of ITC's potential - and above all fundamentally down-to-earth -- contributions to efficacious public health prevention and patient care. As one cogent example:
"Critics of the approach of this book might argue that it is impossible to separate ethnomedical beliefs that are traditional from those that have been influenced - perhaps heavily so - by Western biomedical ideas and education. My response is that African ethnomedicine, like African religion, seems always to have been an open, changing, adaptive system that incorporates new ideas and beliefs even if it reworks them to suit existing beliefs. And, from a practical viewpoint, it does not matter how much biomedical ideas about, for example, microbes has influenced indigenous "germ" theories of unseen insects. What is important is the nature and content of the present belief system, however blended and syncretistic it might be. The fact that some Swazi bogobela - master healers who train initiates - teach that bilharzia [Schistosomiasis] is caused by snail-contaminated water only proves that new, foreign ideas have been adapted and adopted into the present etiological system by its most conservative and influential participants. It is the present belief system - not an imagined pure system of the past - that needs to be understood by those in public health who would influence popular health beliefs and practices in ways deemed compatible with public health (p. 202)."
Anthropologists and other readers interested in the evolutionary and other bio-socio-cultural (pre)historical underpinnings to ITC will find the book's theoretical reflections, summarized in the final chapter, especially thought-provoking. Green argues for a more visible place at the table for his and similarly adaptive anthropological perspectives concerning the complex interface between environment, disease and population in human societies. His conclusion is that "Undue focus on witchcraft beliefs and practices by anthropologists and others has not contributed to the incorporation of ethnomedical findings in public health programs - something many anthropologists bemoan as a serious oversight. However, we are more likely to see health programs informed by ethnomedical research if we place more emphasis where it deserves to be: not on witchcraft beliefs - which is probably the area of least compatibility between indigenous medicine and Western public health - but instead on naturalistic understandings of contagious illnesses" (p. 269-70).
My only criticism of this consistently high-caliber work concerns a reference in Green's book to the frequently cited notion of "super-strains" or unusually virulent subtypes of HIV (p. 181). Max Essex, chair of the Harvard AIDS Institute, and some other researchers have speculated that certain strains, or "clades," of HIV may be more prevalent and hence more infectious among heterosexual populations - thereby explaining, at least in part, the striking discrepancies in HIV rates apparent between different world regions. However, the current consensus among most epidemiologists and virologists is that Essex's initial speculation was incorrect. Melissa Pope of Rockefeller University and Essex himself have tried and failed to reproduce his preliminary results in the laboratory. In Haiti and some other Caribbean and Latin American countries, there are heterosexual epidemics with predominately the same "clade B" virus found in the U.S. and Western Europe, and the Philippines and some other low-HIV countries have exposure to those clade C and E "superstrains" ravaging through such high-HIV areas as Thailand and the "AIDS Belt" of Eastern/Central and Southern Africa. Inspired by Green's own manner of thinking, should we not look primarily to different social environments and cultural-behavioral practices to account for such epidemiological phenomena?
This minor point aside, few readers will be disappointed by Edward's Green's latest and most incisive contribution to the evolving exploration into the multiplicity of human cultures and their rich and complex array of traditional (and modern) healing systems.

The learning of string theory can be a formidable undertaking for those who lack the mathematical background. Indeed, a proper understanding of string theory, not just a forma one, will require a solid understanding of algebraic and differential geometry, algebraic topology, and complex manifolds. There are many books on these subjects, but I do not know of one what will give the student of string theory an in-depth understanding of the relevant mathematics. These two volumes include two rather lengthy chapters on mathematics, one on differential geometry and the other on algebraic geometry. The mastery of these two chapter will give readers a formal understanding of the mathematics, and will allow them to perform calculations in string theory efficiently, but do not give the insight needed for extending its frontiers. There have been a few books published on string theory since these two volumes appeared, but they too fail in this regard (and some even admit to doing so). To gain the necessary insight into the mathematics will entail a very time-consuming search of the early literature and many face-to-face conversations with mathematicians. The "oral tradition" in mathematics is real and one must embed onself in it if a real, in-depth understanding of mathematics is sought.
The physics of string theory though is brought out with incredible skill by the authors, and the historical motivation given in the introduction is the finest in the literature. Now legendary, the origin of string theories in the dual models of the strong interaction is discussed in detail. The Veneziano model, as discussed in this part, has recently become important in purely mathematical contexts, as has most every other construction in string theory. The mathematical results that have arisen from string theory involves some of the most fascinating constructions in all of mathematics, and mathematicians interested in these will themselves be interested in perusing these volumes, but will of course find the approach mathematically non-rigorous.
Some of the other discussions that stand out in the book include: 1. The global aspects of the string world sheet and the origin of the moduli space, along with its connection to Teichmuller space. 2. The world-sheet supersymmetry and the origin of the integers 10 and 26 as being a critical dimension. In this discussion, the authors give valuable insight on a number of matters, one in particular being why the introduction of an anticommuting field mapping bosons to bosons and fermions to fermions does not violate the spin-statistics theorem. 3. The light-cone gauge quantization for superstrings. The authors show that the manifestly covariant formalism is equivalent to the light-cone formalism and is ghost-free in dimension 10. The light-cone gauge is used to quantize a covariant world-sheet action with space-time supersymmetry, with this being Lorentz invariant in dimension 10. This allows, as the authors explain in lucid detail, the unification of bosonic and fermionic strings in a single Fock space. 4. Current algebra on the string world sheet and its origin in the need for distributing charge throughout the string, rather than just at the ends. The origin of heterotic string theory is explained in this context.
But probably the greatest reason to purchase this title is the insight into string theory that is offered by these particular authors --- individuals who have each served as principle architects of string theory since its inception and through its many revolutions.
In general, the prose is congenial as is the level of sophistication in physical and mathematical argument. The mathematical apparatus of string theory can become very heavy very quickly and these authors orient the reader in that difficult terrain in a truly adroit fashion.

However, what seperates this book from other books on the subject of economics, is its philosophical tint. In one of the most interesting chapters the author explains the "tyranny of discounting" and goes on to show that this may not always be a rational and equitable process for the valuation of future hapiness, or suffering. Indeed there are many forms of efficiency but these may not always be equitable. The implications being that current reduction of capital for future generations is not just.
Overall, although the book is over a decade old, it is still both interesting and relevent for anyone that cares about the future state of the world.

I would recommend this book to anyone looking for special-occasion recipes. Everything I've cooked out of it has turned out great, and I would definately consult it for dinner parties or similar occasions. But I don't think it will be a particularly useful cookbook for busy people trying to eat in a reasonably healthy manner.
As has been mentioned in other reviews here, the recipes are somewhat complicated. I am slowly working my way through the book and have already attempted almost 50 of the recipes.
The first few recipes were daunting and I was tempted to give up on the book, but the more recipes I tried, the easier it got. I found that I was learning something.
As others have mentioned, I also don't have all day to prepare a meal, and more often than not, I will only cook from this book on weekends, though to be fair, not all of the recipes are as time-consuming as they seem.
I highly recommend this book to anyone who also considers cooking a hobby and not just a means to an end.
I personally am not a vegetarian, but these recipes take your vegetables and taste buds beyond your wildest dreams. I would recommend this cook book to anyone who likes cooking and eating fine food. If you're looking for easy recipes that take 10 minutes, you'll have to settle for hamburger helper or kraft macaroni and cheese... this is not the place for you! But if you love cooking and love trying new recipes, this is one to add to your collection.
