"In this intriguing work, Mortimer J. Adler probes the intellect's uniqueness, its relation to artificial and extraterrestrial intelligence, the role of language in relation to mind and meaning, and the uses, misuses and disuses of the intellect."--Back cover.

Mortimer Adler has always been ahead of his time. In 1982, before the current revival of interest in angels, Dr. Adler published "The Angels and Us", an engaging look at the various images and hierarchies of angels (including guardian angels). Dr. Adler, the bestselling author of "Ten Philosophical Mistakes", "Aristotle for Everybody", and "The Great Ideas", speculates on the existence of angels; why Jews, Christians, and Muslims believe in angels, and the ways angels have been viewed as objects of religious belief and philosophical thought. This is a wonderfully enlightening work on the affinities between angels and human beings.

Ultimately, Adler's work develops an approach to the separation between scientific and philosophical questions which stands as a model of philosophical consideration of new scientific discoveries and their consequences for the human person.

Interracial Housing was first published in 1951. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. One of the most crucial strains on democracy today is the practice of racial segregation. In the press, in local, state, and federal government agencies, in fact, wherever people thrash out the problems of democratic living, the question is being discussed. This book offers facts which throw new light on an important issue in the overall problem of racial segregation. Here are the results of a study comparing two kinds of public housing—segregated and non-segregated. Two low-rent, public housing projects in which Negroes and whites live as next door neighbors were compared with two similar housing developments in which Negroes and whites are assigned to separate buildings or areas. The study reveals how the people living in these contrasting ways differ in their social relations, community morale, racial attitudes, and other significant social aspects. The research procedures used are explained, and general conclusions about changing prejudices are offered. Social scientists, psychologists, housing officials, and community leaders concerned with the problems not only of housing but of race relations in general will find helpful guidance here. In addition to providing much-needed data on an important social problem, the book offers a valuable demonstration of research techniques in social science.

Reviewing 40 years of hard, empirical data, from China and India to Chile and Iraq, the authors show that poor democracies beat poor autocracies in every economic measure. In addition, the authors offer dramatic evidence that democracies are less likely to fight each other and that terrorists more often find safe haven in authoritarian countries such as Egypt, Saudi Arabia, and Pakistan.

"Chemical Engineering: An Introduction is designed to enable the student to explore a broad range of activities in which a modern cheical engineer might be involved by focusing on mass and energy balances in liquid-phase processes. Thus, in one semester, the student addresses such problems as the design of a feedback level controller, membrane separation, and hemodialysis, optimal design of a process with chemical reaction and separation, washout in a bioreactor, kinetic and mass transfer limits in a two-phase reactor, and the use of the membrane reactor to overcome equilibrium limits on conversion. Mathematics is employed as a language, but the mathematics is at the most elementary level and serves to reinforce what the student has already studied; nothing more than basic differential and integral calculus is required, together with elementary chemistry. Students using this text will understand what they can expect to do as chemical engineering graduates, and they will appreciate why they need the courses that follow in the core curriculum"--

During his eighteen-plus years in prison, five of which were spent at U.S.P. Alcatraz in the middle of San Francisco Bay, Morton Sobell learned well the price of "doing time." In 1951, during the dark days of McCarthyism and the Red Scare, Julius and Ethel Rosenberg and Morton Sobell were convicted of conspiracy to commit espionage. Sobell was sentenced to thirty years in prison. The Rosenbergs were sentenced to death and were later executed. The trial remains one of America's most controversial. This is the story of what led up to the trial, to the conduct of the trial--including an account of justice subverted to political ends--and of one man's odyssey through Depression-era radicalism and the hard world of the United States prison system. It is also the story of an intelligent man determined not to be broken, determined to achieve vindication. As part of that effort, after he was released, the author obtained hundreds of previously classified FBI documents that graphically demonstrate the goverment's motives and methods during the Rosenberg-Sobell trial, and beyond. The most relevant of these documents are included on a CD (which comes with the book), giving the reader a rare opportunity to compare the author's original suppositions and his adversary's documentation of its strategy.

This book is intended primarily as a guide for the opera goer. It includes a synopsis of the plot, with indications of the themes and motifs used in it, and discusses the style of the opera, Tosca being a typical example of Italian naturalism in operas, verismo. It compares Puccini's libretto with Sardou's play La Tosca, analyses the close-knit structure of the work and examines salient points in the music. It also describes the genesis of the work (quoting wherever appropriate, Puccini's own remarks about it), its first production and early reception. A subsidiary aim of the book is to present the opinions, positive and negative, that have been expressed by various critics about the opera since its first production in 1900. There are contributions from the celebrated singer and producer of Tosca Tito Gobbi, and two other musicologists, Roger Parker and William Ashbrook. Malcolm Walker has provided a discography.

The Warsaw Ghetto Uprising has become a symbol of heroism throughout the world. A short time before the uprising began, Pawel Frenkel addressed a meeting of the Jewish Military fighters: Of course we will fight with guns in our hands, and most of us will fall. But we will live on in the lives and hearts of future generations and in the pages of their history.... We will die before our time but we are not doomed. We will be alive for as long as Jewish history lives! On the eve of Passover, April 19, 1943, German forces entered the Warsaw ghetto equipped with tanks, flame throwers, and machine guns. Against them stood an army of a few hundred young Jewish men and women, armed with pistols and Molotov cocktails. Who were these Jewish fighters who dared oppose the armed might of the SS troops under the command of SS General Juergen Stroop? Who commanded them in battle? What were their goals? In this groundbreaking work, Israel s former Minister of Defense, Prof. Moshe Arens, recounts a true tale of daring, courage, and sacrifice that should be accurately told out of respect for and in homage to the fighters who rose against the German attempt to liquidate the Warsaw ghetto, and made a last-ditch fight for the honor of the Jewish people. The generally accepted account of the Warsaw Ghetto Uprising is incomplete. The truth begins with the existence of not one, but two resistance organizations in the ghetto. Two young men, Mordechai Anielewicz of the Jewish Fighting Organization (ZOB), and Pawel Frenkel of the Jewish Military Organization (ZZW), rose to lead separate resistance organizations in the ghetto, which did not unite despite the desperate battle they were facing. Included is the complete text of The Stroop Report translated into English.

This book examines the meaning and nature of Idolatry - and, in doing so, reveals much about the monotheistic tradition that defines itself against this sin. The authors consider Christianity and Islam but primarily on Judaism. They explore competing claims about the concept of idolatry that emerges in the Hebrew Bible as a "whoring after false Gods." The Authors show how this debate, over idolatry as practice or error, has taken shape and has, in turn, shaped the course of Western thought.

In this book, the world's foremost scholar of Kabbalah explores the understanding of erotic love in Jewish mystical thought. Encompassing Jewish mystical literatures from those of late antiquity to works of Polish Hasidism, Moshe Idel highlights the diversity of Kabbalistic views on eros and distinguishes between the major forms of eroticism. The author traces the main developments of a religious formula that reflects the union between a masculine divine attribute and a feminine divine attribute, and he asks why such an "erotic formula" was incorporated into the Jewish prayer book. Idel shows how Kabbalistic literature was influenced not only by rabbinic literature but also by Greek thought that helped introduce a wider understanding of eros. Addressing topics ranging from cosmic eros and androgyneity to the affinity between C. J. Jung and Kabbalah to feminist thought, Idel's deeply learned study will be of consuming interest to scholars of religion, Judaism, and feminism.

The "Gorbachev phenomenon" is seen as the product of complex developments during the last seventy years--developments that changed the Soviet Union from a primarily agrarian society into an urban, industrial one. Here, for the first time, a noted authority on Soviet society identifies the crucial historical events and social forces that explain Glasnost and political and economic life in the Soviet Union today.
