Just as the development of relativity theory and quantum mechanics have been the defining events of twentieth-century science, the burgeoning field of cognitive science is often trumpeted as being a glimpse into the future of the center of science in the coming century. In this paper, we examine this claim, asking whether the so-called cognitive “revolution” is indeed revolutionary or, on theother hand, is merely a flash-in-the-pan, scientifically speaking. As a point of perspective on this question, the paper looks at (...) the claims and accomplishments of artificial inteIligence, as well as the research agenda of workers in the currently fashionable field of artificial life. The paper concludes with some speculations about what directions the “cognitive revolution” is likely to take over the comingdecade or two. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:"EVERY MARITAL ACT OUGHT TO BE OPEN TO NEW LIFE'': TOWARD A CLEARER UNDERSTANDING I. INTRODUCTION NE FREQUENTLY encounters misinterpretations of the statement " Every marital act ought to be open to new life " and similar statements in recent Catholic teaching concerning contraception.1 There are two common misinterpretations. One is: No couple may engage in marital intercourse without the intention to procreate. The other is: No couple may (...) engage in marital intercourse at times when they think procreation is impossible. As interpretations of the Church's teaching, these must be mistaken. For the Church teaches that contraception is always wrong and that natural family planning (NFP) is not always wrong. But NFP facilitates intercourse without the intention to procreate at times when procreation is thought to be impossible. Moreover, the Church has never taught that marital intercourse is good only if the couple desires to procreate; indeed, couples known to be sterile have never been forbidden to marry. We think that the only plausible interpretation of "Every marital act ought to be open to new life" is: It is wrong for those who engage in marital intercourse to attempt to impede the transmission of life which they think their act otherwise might bring about. For if they do try to impede that to which their act of itself might lead, they choose to close it to new life. 1 The proposition is formulated somewhat differently by Paul VI, Humanae vitae, 11, AAS 60 (1968), 488 (with references to Gasti connubii and to Pius XII's.Allocution to the Society of Italian Catholic Midwives); and by John Paul II, Familiaris consortia, 29, AAS 74 (1982), 115, following proposition 22 of the 1980 session of the Synod of Bishops. Moreover, the different formulations also are translated diversely. We do not think these differences matter for our present purpose. 365 366 GRISEZ, BOYLE, FINNIS AND MAY Un.derstood in this way, "Every marital act ought to be open to new life" expresses the same proposition as " Contraception is always wrong." Nevertheless, the affirmative formulation helps to clarify what contraception is, for it indicates the precise object of the contraceptive act. "Contraception" signifies only the prevention of conception, but the contraceptive act seeks to impede the beginning of the Zife of a possible person. The distinction is only conceptual, but we think it important, for the explicit reference to new life calls attention to the fact that contraception is a contralife act. The characterization of contraception as a oontralife act is one major element of the unbroken Christian tradition condemning contraception as always wrong. For example, a canon, Si aliquis, concerning contraception was included in the Church's universal law from the thirteenth century until 1917: " I£ anyone for the sake of fulfilling sexual desire or with premediated hatred does something to a man or to a woman, or gives something to drink, so that he cannot generate, or she cannot conceive, or offspring be born, let it be held as homicide." 2 This canon does not say that contraception is homicide ; the tradition made no such mistake. The canon rather says that contraception sihould be regarded as homicide is regarded. To regard contraception as homicide is regarded is not only to make it clear that.contraception is wrong, but also to point to its being contralife as the reason why it is wrong. When contraception is regarded as contralife, it is seen as evil outside marriage as well as within. Historically, contraception probably was more common among the unmarried than the married, and much of the tradition condemned contraception without distinguishing between its uses in and outside mar2 Deoret.

Text John Toland a jeho Křesťanství bez mystérií sestává ze dvou provázaných částí. První část představuje stručné biografické pojednání o Johnu Tolandovi (1670–1722), v němž se mimo jiné snažíme předložit obecný úvod do jeho myšlení. Druhá část pak nabízí první český překlad předmluvy k Tolandovu nejznámějšímu spisu Christianity not Mysterious (1696), který je považován za základní impulz deistické diskuze na Britských ostrovech.

As John Casti wrote, "Finally, a book that really does explain consciousness." This groundbreaking work by Denmark's leading science writer draws on psychology, evolutionary biology, information theory, and other disciplines to argue its revolutionary point: that consciousness represents only an infinitesimal fraction of our ability to process information. Although we are unaware of it, our brains sift through and discard billions of pieces of data in order to allow us to understand the world around us. In fact, most (...) of what we call thought is actually the unconscious discarding of information. What our consciousness rejects constitutes the most valuable part of ourselves, the "Me" that the "I" draws on for most of our actions--fluent speech, riding a bicycle, anything involving expertise. No wonder that, in this age of information, so many of us feel empty and dissatisfied. As engaging as it is insightful, this important book encourages us to rely more on what our instincts and our senses tell us so that we can better appreciate the richness of human life. (shrink)

"_The Moment of Complexity_ is a profoundly original work. In remarkable and insightful ways, Mark Taylor traces an entirely new way to view the evolution of our culture, detailing how information theory and the scientific concept of complexity can be used to understand recent developments in the arts and humanities. This book will ultimately be seen as a classic."-John L. Casti, Santa Fe Institute, author of _Gödel: A Life of Logic, the Mind, and Mathematics_ The science of complexity (...) accounts for that inscrutable mix of chaos and order that governs our natural world. Complexity explains how networks emerge and function, how species organize into ecosystems, how stars form into galaxies, and how just a few sequences of DNA can account for so many different life forms. Recently, the idea of complexity has taken the worlds of business and politics by storm. The concept is used to account for phenomena as varied as the behavior of the stock market, the response of voting populations, and the effects of risk management. Even Disney has used complexity theory to manage crowd control at its theme parks. Given the startling development of new information technologies, we now live in a moment of unprecedented complexity, an era in which change occurs faster than our ability to comprehend it. With _The Moment of Complexity_, Mark C. Taylor offers a timely map for this unfamiliar terrain opening in our midst, unfolding an original philosophy through a remarkable synthesis of science and culture. According to Taylor, complexity is not just a breakthrough scientific concept, but the defining quality of the post-Cold War era. The flux of digital currents swirling around us, he argues, has created a new network culture with its own distinctive logic and dynamic. Drawing on resources from information theory and evolutionary biology, Taylor explains the operation of complex adaptive systems in social and cultural processes and captures a whole new zeitgeist in the making. To appreciate the significance of our emerging network culture, he claims, we need not only to understand contemporary scientific and technological transformations, but also to explore the subtle influences of art, architecture, philosophy, religion, and higher education. _The Moment of Complexity_, then, is a remarkable work of cultural analysis on a scale rarely seen today. To follow its trajectory is to learn how we arrived at this critical moment in our culture, and to know where we might head in the twenty-first century. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Call for New Theological Reflection on the Sacramental Character of Marriage and the Thought of St. ThomasLawrence J. WelchTheologians across the theological spectrum have called attention to the urgent need for a new reflection on the theological and sacramental character of marriage. Peter Hünermann, known for his strong criticism of magisterial teachings on marriage, and the late Cardinal Carlo Caffarra, known for his equally strong defense of them, (...) have both drawn attention to this need. At an international symposium in September 2015, held in Rome prior to the Ordinary Synod of Bishops on Marriage and the Family, Hünermann gave a presentation entitled "On the Specific Theological Character of the Sacrament of Matrimony."1 The symposium aimed at providing a critical and scholarly discussion of new and constructive perspectives for the Church doctrine on marriage and family life in time for the 2015 synod on the family.2 Some of Hünermann's work from this paper also came to be known from an interview in Commonweal magazine where he summarized some of the main points of his symposium presentation.3 In the interview, he also revealed that before the 2015 synod he [End Page 845] was invited to speak with Pope Francis about the theology of marriage. Understandably, this meeting heightened interest in the German theologian's thought.Hünermann argues that "the specific character of the sacrament of marriage, which is very closely connected to the dying of the marriage bond,... has scarcely been the object of theological reflection, [and] is almost unknown in the consciousness of the bishops." 4 Hünermann appeals to St. Thomas as a way forward for understanding the theological character of marriage. This appeal is situated within a wider examination5 that offers an elaboration and new interpretation of "the specific dogmatic characteristics of the sacrament of matrimony that emerge in today's situation from a critical comparison of the encyclical Casti connubii and the Catholic theological tradition, especially the theology of St. Thomas."6 Sharply critical of the encyclical, Hünermann sees it as having saddled the Church with a legalistic concept of marriage elevated above history that is too far removed from the Catholic theological tradition and St. Thomas's theology of marriage.The year before his death, Cardinal Caffarra gave the 2016 graduation address at the John Paul II Institute for Marriage and Family in Washington, DC.7 Among the challenges he identified for the institute to address was the [End Page 846] need for theological reflection on the sacramental character of marriage. Referring to his earlier work, he pointed out that theology after the Council of Trent "lost the awareness of sacramental ontology, of the real transformation produced by the sacrament in the persons of the spouses [res et sacramentum]."8 Furthermore, according to Caffarra, the "theology of the conjugal covenant was supplanted by the notion of a contract, as a human act by which two persons commit to one another." The sacramental character was thought of as consisting of the assurance of divine graces given to fulfill the contract. Caffarra claimed that, "consequently, the words of Jesus 'What God has joined together, let not man put asunder,' lost all their realistic force. Absolute indissolubility, once the sacrament was perfected [=a ratified, consummated marriage], became essentially indefensible."9The primary interest of this paper is to respond to the call for a renewed theological reflection on the specific character of the sacrament of marriage. I wish to take up Caffarra's suggestion to focus on the sacramental character (res et sacramentum) on the one hand, and on the other hand, Hünermann's suggestion that a kind of ressourcement from St. Thomas Aquinas's theology of marriage can be of great help for a fresh theological reflection on the specific character of the sacrament of marriage. Although I agree with Hünermann that a renewed consideration of the thought of St. Thomas can be a way forward, I differ from him on how it can be. Hünermann notices that St. Thomas speaks of the grace of the sacrament of marriage as a helping grace.10 St. Thomas does indeed speak this way of the... (shrink)

This superb collection by the eminent physicist and critic John Ziman, opens with an album of portraits of scientists--Albert Einstein, Freeman Dyson, Lev Landau, Mark Azbel, Andrei Sakharov. Ziman takes readers into the world of the contemporary scientist, showing how discoveries are made and how claims are tested. He then travels into the minds of scientists as they are drawn into competing directions. Here Ziman exposes the path of discovery, which is strewn with complex human needs, governmental restrictions, the (...) desire for profits, and the exercise of technical virtuosity. (shrink)

In this book John Ziman seeks the answers to crucial questions facing scientists who need to change the direction of their careers.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 155 Humanae Vitae: A Generation Later. By JANET SMITH. Washington, D.C.: The Catholic University of America Press, 1991. Pp. xvi + 425. $42.95 hardcover; $17.95 paper. This is an ambitious and important study. I will first offer an overview of the volume to indicate its scope and note some of its major features. I will then respond briefly to some of the major criticisms Smith makes of (...) the argument against contraception advanced by Germain Grisez, Joseph Boyle, John Finnis, and myself. The work contains 8 chapters and 4 appendices. Chapters 3 and 4, as Smith says, "provide an analysis of Humanae Vitae itself and thus constitute the heart of the hook" (p. xi). Since this is so I will first summarize briefly Chapters 1, 2, 5, 6, 7, and 8 and then center atten· tion on the two central chapters and the four appendices. Chapters 1 and 2 provide the context for Humanae Vitae. The first chapter is devoted largely to an account of the so-called " Minority " and "Majority" documents of the Papal Commission for the Study of Problems of the Family, Population, and Birth Rate, while the second seeks to summarize Catholic teaching on Christian marriage prior to the encyclical. This summary draws principally from Pius XI's Casti Connubii and from nn. 47-52 of Vatican II's Gaudium et Spes. Smith takes up in some detail the issue of the" primacy" of procreation, concluding that Gaudium et Spes " seems to sidestep " this issue which, in her judgment, is irrelevant to the question of contraception. She thinks that this central document of Vatican II sent " mixed signals " on the question of contraception, although she believes that several passages " can very plausibly he read to support the position that contraception is portrayed as a violation not only of the procreative good of marriage hut also of the values of conjugal love" (p. 66). Chapter 5 deals with a wide range of theological issues: the biblical foundations for the teaching found in Humanae Vitae, the relevance of the concept of munus for this teaching, the possibility of acting " in good conscience " in a way contrary to its teaching, and the infallibility of the teaching. Of special value is the extended discussion of the con· cept expressed by the Latin term munus. Smith examines the rich meaning of this term in several magisterial documents, including Gaudium et Spes as well as Humanae Vitae. While a munus implies duties, it is essentially a noble, honor-bringing "gift" or "reward," signifying a vocation and sublime honor. Paul VI, in developing the integral vision of marriage in his encyclical, uses this concept to show that God, in giving to spouses the munus of handing on new life, has conferred on them the honor of sharing with him in the work of bring· 156 BOOK REVIEWS ing new life into the world. Smith shows beautifully how the rich theological meaning of this term helps " illuminate and enrich " the teaching of the encyclical. Chapters 6 and 7 investigate the arguments presented by dissenting theologians after Humanae Vitae to justify their repudiation of its teaching. In Chapter 6 Smith considers the views of Charles Curran and Bernard Haering, while in Chapter 7 she examines the proportionalist approach to moral issues developed by Joseph Fuchs, Richard McCormick and others. She provides intelligent criticism both of Curran and Haering and of proportionalist thought, focusing on the repudiation of specific moral absolutes. In Chapter 8 Smith provides a very helpful summary of Pope John Paul II's understanding of the human person, human sexuality and marriage. In particular, she takes up his notion that in marriage and in the act proper rto it man and woman make a " gift " of themselves to one another. Simultaneously to choose to give themselves to each other in the marital act and to contracept is then seen to involve an inner contradiction, a falsification of the " language of the body " (pp. 230258 ). Smith also takes up some of the major criticisms levelled against John Paul II's thought, in particular Lisa Sowle Cahill's, which charges him with an overromantic view of love and a failure to recognize that...

The paper explores the possible contribution of Familiaris consortio to a contemporary theology of marriage. It argues that the exhortation and its author, Pope John Paul II, may be credited for two major innovations in the magisterial teaching: first, in taking its starting point from the human person and her capacity to love, the document has definitely overcome the earlier view, clearly articulated e.g. in Pius XI’s encyclical Casti connubii, which looked at marriage primarily in terms of a (...) natural institution and only in a second instance at its interpersonal value; second, it has attributed to marriage and the family a position in the mystery of salvation and consequently in the mission of the Church, which is unprecedented in previous teaching. However, by equating 'God’s plan for marriage' with the 'nuptial mystery of salvation' and by imposing onto human marital love the model of Christ’s total self-giving, the papal exhortation ultimately forfeits what it seemed to have gained in terms of a renewed theology of marriage: it ultimately fails to recognize that God’s salvific plan does not float above history but takes shape in the concrete lives of couples and families and that their lived experiences should therefore be given a place in theology and in the mission of the Church.

The essays in this volume blend historical and philosophical reflection with concern for contemporary political problems. They show that the causes and motivations of civil religion are a permanent fixture of the human condition, though some of its manifestations and proximate causes have shifted in an age of multiculturalism, religious toleration, and secularization.

While previous studies of Dewey's work have taken either a historical or topical focus, Shook offers an innovative, organic approach to understanding Dewey and eloquently shows that Dewey's instrumentalism grew seamlessly out of his idealism. He argues that most current scholarship operates under a mistaken impression of Dewey's early philosophical positions.

Practical wisdom and judgment, rather than seen as ‘things’ hidden inside the mind, are best talked of, we suggest, as emerging developmentally within an unceasing flow of activities, in which practitioners are inextricably immersed. Following a performative line of thinking, we argue that when practitioners (namely, individuals immersed in a practice, experiencing their tasks through the emotions, standards of excellence and moral values the practice engenders or enacts) face a bewildering situation in which they do not know, initially at least, (...) how to proceed, the judgment they exercise emerges out of seeking to establish a new orientation to their puzzling surroundings. They do so through actively trying to be in touch with their felt emotions and moral sensibilities, while attempting to articulate linguistically the feelings experienced in order to get a clearer view of relevant aspects of the situation at hand. Coming to a judgment involves moving around within a landscape of possibilities, and in so doing, being spontaneously responsive to the consequences of each move, and assessing which one (or combination of moves) seems best in resolving the initial tension aroused in one’s initial confusion.
