Example Input: poetry in Riis' How he oher half Lives . How the Other Half Lives was written over a century ago as an expose' of the appalling living conditions in the tenements of New York City. The author speaks with a crusader's zeal and with so much detail that the reader can visualize these tenements, these streets, and these people as if they were living today. This is a grim and moving portrayal of the lives of the men, the women and the children that inhabit these loathsome neighborhoods of New York City in the late 1800s.  He so graphically describes the filth, the sunless and airless rooms, the crowding, and the starvation that these places palpably exist for the reader and bring a chill to any heart.  Riis has a genuine concern for the tenement situation and understands these people's plight. His pictures are touching and meant to vividly show their misery. He, for the most part, blames the money-hungry landlords for these crowded conditions: "How shall the love of God be understood by those who have been nurtured in sight only of the greed of man." (p. 266). He laments that the tenement is three quarters responsible for the misery of the poor. Then, after his extensive discourse, he offers three concrete cures for these dreadful conditions, something that many authors forget when they are enlightening readers.   Riis states his purpose for writing this book himself on page 297 when he says, "If this book shall have borne ever so feeble a hand in garnering a harvest of justice, it has served its purpose." The author apparently succeeded with his purpose, because in the flyleaf of this book the publisher tells us: "This book helped bring about new revisions in the housing codes of the major U. S. cities."  How does this book relate to adult education? By moving chronologically from the founding of America to the slums of NYC in the 1800s, are we to understand that education took a back seat to the accumulation of money during those hundred years? Certainly Riis posits that education is one of the solutions to this problem while at the same time implying that wealth accumulation and the lack of education has been the cause of this problem.  "Thus the whole matter resolves itself once more into a question of education, all the more urgent because these people are poor, miserably poor almost to a man." (p. 147). He does not forget that this "education" is not only for the poor people, but also for the wealthy landlords. "Clearly, it is a matter of education on the part of the landlord no less than the tenant." (p. 270). Riis' almost missionary language exhorts us to never allow greed to override a compassion for humanity.  "It is a fight in which eternal vigilance is truly the price of liberty and the preservation of society." (p. 233). The relation of this book to the other units of study in this course could be explained as an example of how low mankind can descend if education is not considered one of the major cornerstones of a society.  Although this book was exhaustive in its detail, it was easy to read while at the same time enlightening. I found myself enjoying the ranting tone and the fascinating lists of neighborhoods and the labels that Riis used for the different races. In a sense it reads like a Ginsberg poem; constantly hitting the reader with melodious lists of places and people from another era. Read these geographic names out loud and feel their rhythm:  Jewtown, Bandit's Roost, Double Alley, The Bowery, The Bloody Sixth Ward, The Fourth, Fifth and Tenth Wards,  Blindman's Alley, The Bend, The Battery, Little Italy, The French Quarter, Hell's Kitchen, The West Side, Bottle Alley, Frog Hollow, Poverty Gap, Murderer's Alley, Gotham Court, The Old Brewery, Old Africa, Potter's Field, Blackwell's Island Asylum, Rogues' Gallery, Penitentiary Row, Chinatown. The list goes on. To someone reared in rural America, this chant sounds like a song about another country.    Riis also has something to say about all the races of people that live in the tenements of New York City:   Chinaman (he can't be taught), (Chinese (coolie--laundry business), Polish Jew (coops himself up in his den with his thermometer at boiling), Russian Jew, Jew (money is their God), Bohemian (poor, but thrifty), Blacks (like to gamble, but they are clean), Greek, Hebrews (tailors, all of them), Dutchman, Irish (like to drink and have expensive funerals), German (order loving), Swiss, Pasquales, Russian, Italian (a born gambler; lighthearted and gay), Swamp Angel (thieves), Street Arabs (army of homeless boys), Tramps and Toughs (the world owes them a living),and the Celtics. I was enthralled by the street lingo and the colloquialisms and Riis' comments about every race.   I noticed one interesting similarity between the late 1800s and the present day. Riis says that the gap between the social classes is widening everyday. I hear people talking about the growing differences between the rich and the poor often these days. Does every generation think that is happening in their time?   Not only should this book be used by people researching New York City`s tenements, but it should also be read by everyone seeking a blueprint for social change. It is a reminder to show us how hopeless the human circumstances can become when man's greed overrides his concern for human dignity.

Example Input: Habermas' Opus is Timely! . The German political and social philosopher Jurgen Habermas is heir to the semantically rich tradition of Frankfurt School thinkers. These men (and sadly, they are mainly men, although Hannah Arendt is in some sense in this circle) were seriously threatened by the collapse of the Weimar Republic. Their decision to go into exile in the United States should probably be controversial. Habermas is profoundly influenced by Marx, Weber, Freud, and Talcott Parsons, and wrote this book in the context of uprisings against the Viet Nam War. What we are seeing right now, Bush versus Gore in a contested election in which the very structure of the United States government is being questioned, could be illuminated by careful study of this book. I commend it to the attention of anyone who would better understand a moment in United States history which has been descibed as a constitutional crisis

Example Input: Engaging look at a scary set of diseases . Deadly feasts: tracking the secrets of a terrifying new plague by Richard Rhodes is one scary book. It tracks the discovery of prions, the mishapen proteins responsible for mad cow disease, scrapie, and Creutzfeldt Jacob disease. Following human cannibals in the jungles of New Guinea in the fifties, bovine cannibals of the British Isles in the eighties, and the bizarre history of sheep scrapie from the 17th century on, Rhodes does a great job of presenting the history and discovery of this bizarre group of diseases. I especially enjoyed the characterizations of the scientists, from the Noble Laureate who so enjoyed the New Guinea that he often regretted rejoining civiliziation, yet brought thirty natives back to the USA and helped them through school, to the hyper-competitive scientist who named the molecules even though he wasn't quite certain what they were.     But this isn't just a story of scientific discovery. As the foreboding subtitle blares, Rhodes explores some of the scarier aspects of prions. These include spontaneous formation, responsible for the known early cases of Creutzfeldt Jacob disease, trans-species infection, including mad cow disease and scrapie, the long long incubation period and lack of immune system response, and hardiness of the disease. One scary factoid: a scientist took a sample of scrapie, froze it, baked it for an hour at 360 degrees (celsius), and was able to re-infect other animals from this sample.     For all the uneasiness this book inspires, it certainly doesn't offer any answers. A condemnation of industrial agriculture, a warning that it's unknown whether vegetarians are even safe, and a caution against using bone meal for your flower garden do not make a recipe for handling this issue. To be fair, it was printed in 1997--perhaps things are under control now.
