The similarities and differences in dream content at the cross-cultural, gender, and individual levels provide one starting point for carrying out studies that attempt to discover correspondences between dream content and various types of waking cognition. Hobson and Kahn’s . Dream content: Individual and generic aspects. Consciousness and Cognition, 16, 850–858.) conclusion that dream content may be more generic than most researchers realize, and that individual differences are less salient than usually thought, provides the occasion for a review of findings (...) based on the Hall and Van de Castle . The content analysis of dreams. New York: Appleton-Century-Crofts.) coding system for the study of dream content. Then new findings based on a computationally intensive randomization strategy are presented to show the minimum sample sizes needed to detect gender and individual differences in dream content. Generally speaking, sample sizes of 100–125 dream reports are needed because most dream elements appear in less than 50% of dream reports and the magnitude of the differences usually is not large.

Research using economic decision-making tasks has established that direct reciprocity plays a role in prosocial decision-making: people are more likely to help those who have helped them in the past. However, less is known about how considerations of mutual exchange influence decisions even when the other party’s actions are unknown and direct reciprocity is therefore not possible. Using a two-party economic task in which the other’s actions are unknown, study 1 shows that prosociality critically depends on the potential for mutual (...) exchange; when the other person has no opportunity to help the participant, prosocial behavior is drastically reduced. In study 2, we find that theories regarding the other person’s intentions influence the degree of prosociality that participants exhibit, even when no opportunity for direct reciprocity exists. Further, beliefs about the other’s intentions are closely related to one’s own motivations in the task. Together, the results support a model in which prosociality depends on both the social conditions for mutual exchange and a mental model of how others will behave within these conditions, which is closely related to knowledge of the self.

A tension between perspectives that emphasize deterministic versus stochastic processes has sparked controversy in ecology since pre-Darwinian times. The most recent manifestation of the contrasting perspectives arose with Hubbell’s proposed “neutral theory”, which hypothesizes a paramount role for stochasticity in ecological community composition. Here we shall refer to the deterministic and the stochastic perspectives as the niche-based and neutral-based research programs, respectively. Our goal is to represent these perspectives in the context of Lakatos’ notion of a scientific research program. We (...) argue that the niche-based program exhibits all the characteristics of a robust, progressive research program, including the ability to deal with disconfirming data by generating new testable predictions within the program. In contrast, the neutral-based program succeeds as a mathematical tool to capture, as epiphenomena, broad-scale patterns of ecological communities but appears to handle disconfirming data by incorporating hypotheses and assumptions from outside the program, specifically, from the niche-based program. We conclude that the neutral research program fits the Lakatosian characterization of a degenerate research program. (shrink)

In this international and interdisciplinary collection of critical essays, distinguished contributors examine a crucial premise of traditional readings of Plato's dialogues: that Plato's own doctrines and arguments can be read off the statements made in the dialogues by Socrates and other leading characters. The authors argue in general and with reference to specific dialogues, that no character should be taken to be Plato's mouthpiece. This is essential reading for students and scholars of Plato.

In this article I elaborate a scientifically based moral realism that I call affordance moral realism, and I offer a promissory note that affordance moral realism is the best current explanation of morality. Affordance moral realism maintains that morality is constituted by the interaction of moral agents and moral affordances. The latter are the natural and social environments in which moral agents’ activities take place and contain the objects of moral agents’ activities whose actualizations are the manifestation of substantive moral (...) goods. In making this argument, I take a scientific naturalistic approach that includes both the natural and social sciences, aiming to make my account both methodologically and substantively naturalistic. On the subject side of my affordance view, I offer a scientific account of moral agency, one based on an extension of social cognitive theories of agency to the realm of morality. And I argue that affordance moral realism explains the nature of moral agency, its acquisition, maintenance, and successful performance. To explain its origin and maintenance, I make use of a general theory of selection that embraces biological, social, cultural, and intentional selection. On the object side, I offer a theory of moral affordances and their actualizations, employing the findings and theories of moral developmental psychology and moral psychology to understand their actualizations through the successful operations of moral agents. I conclude that a scientifically based naturalistic affordance moral realism promises to provide the best current account of morality. It is not only affordable; it’s a bargain. (shrink)

Among the deleted scenes from the theatrical version of Aliens is a short sequence in which the authors learn about Ellen Ripley's daughter, Amanda. This explains why Ripley feels so connected and responsible to the only surviving colonist of Hadley's Hope, second‐grader Rebecca Jorden, known as “Newt”. Ripley's exceptional treatment of Newt shows that the virtues of care and compassion should sometimes override universal rules of justice and fairness. Ripley has made a promise to never leave Newt, and intends to (...) take it seriously. Knowing Newt, caring about Newt, Ripley would rather die than let anything bad happen to her. The powerful point of Aliens is that this is not a moral failing or lack of consideration, but a deep commitment and serious decision. Ripley's oath to rescue Newt is specific, and it is partial.

Arguably, STEM undergraduate education has narrowed student engagement with the social, ethical, and global. Our paper argues that disengagement is caused by a failure of moral imagination. We propose socio-technical analysis as the cornerstone to a more inclusive approach to STEM education. It promotes four activities: (1) zooming in on technologies by describing their structure, function, and embedded values; (2) zooming out to the surrounding socio-technical system which constrains and enables the technology’s functioning; (3) moving back-and-forth through Appropriate Technology to (...) assess the fit of the technology to its socio-technical surroundings; and (4) using the capability approach to finish the (re)engagement process. We then look at graduate and undergraduate student work that has successfully used our framework to combat disengagement and conclude by discussing materials we have used to assess student engagement.

The behavioral sciences have flourished by studying how traditional and/or rational behavior has been governed throughout most of human history by relatively well-informed individual and social learning. In the online age, however, social phenomena can occur with unprecedented scale and unpredictability, and individuals have access to social connections never before possible. Similarly, behavioral scientists now have access to “big data” sets – those from Twitter and Facebook, for example – that did not exist a few years ago. Studies of human (...) dynamics based on these data sets are novel and exciting but, if not placed in context, can foster the misconception that mass-scale online behavior is all we need to understand, for example, how humans make decisions. To overcome that misconception, we draw on the field of discrete-choice theory to create a multiscale comparative “map” that, like a principal-components representation, captures the essence of decision making along two axes: aneast–westdimension that represents the degree to which an agent makes a decision independently versus one that is socially influenced, and anorth–south dimensionthat represents the degree to which there is transparency in the payoffs and risks associated with the decisions agents make. We divide the map into quadrants, each of which features a signature behavioral pattern. When taken together, the map and its signatures provide an easily understood empirical framework for evaluating how modern collective behavior may be changing in the digital age, including whether behavior is becoming more individualistic, as people seek out exactly what they want, or more social, as people become more inextricably linked, even “herdlike,” in their decision making. We believe the map will lead to many new testable hypotheses concerning human behavior as well as to similar applications throughout the social sciences. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS Galileo: For Copemicanism and for the Church. By ANNIBALE FANTOLI. Translated by George V. Coyne, S.J. Studi Galileiani Vol. 3. Vatican City: Vatican Observatory Publications, 1994. Distributed by the University of Notre Dame Press, Notre Dame, Indiana. Pp. xix+ 540. $21.95 (paper). This exhaustive treatment of Galileo and his relationship to the Church was first published in Italian by the Vatican Observatory in 1993 as Vol. 2 (...) of its Studi Galileiani series, bearing the title Galileo: Per il Copemicanesimo e per la Chiesa. So excellent was the study that Father George Coyne, the director of the Vatican Observatory, took it on himself personally to translate the volume into English. Although not a member of the Galileo Commission set up by Pope John Paul II to review the Galileo case, as were Coyne and myself, Fantoli has admirably complemented the work of the Commission and his book surely belongs in the Studi Galileiani collection. A former Jesuit with degrees in mathematics and physics, Fantoli began the book more than twenty-five years ago when he was preparing a course on Galileo at Sophia University in Tokyo. His intention was to show that for Galileo it was never a question of choosing between Copernicanism and the Church, and that the saddest drama of his life was being faced with an injunction that forced him to befor the Church and against Copemicanism. The subtitle of his book proclaims Galileo's true intentions, despite his failure to convince others that this was what his life was all about. A great strength of Fantoli's treatment is its documentation, which abounds in excerpts from Galileo's writings and his correspondence as found in the National Edition of his works and also in citations from new materials that have been uncovered by the Galileo Commission. Thanks to Coyne, all of these texts, many of which were hitherto available only in Latin or Italian, can now be easily accessed in English translation. Another strength of Fantoli's work is that he has kept abreast of Galileo literature over the years and thus is able to offer scholarly critiques of authors whose works exhibit a bias against the Church. Especially welcome are his careful discussions of the positions of earlier writers such as Giorgio de Santillana, Ludovico Geymonat, and Stillman Drake, as well as those of more recent authors, Mario Biagioli, Maurice Finocchiaro, Pietro Redondi, William R. Shea, and Richard S. Westfall. The book is a tour de force and there is little to criticize in it. Unfortunately, however, a typesetting error at its very beginning might create 317 318 BOOK REVIEWS the wrong impression and throw off prospective readers. About six lines of text were omitted at the bottom of page 9. To remedy this the following words should be inserted between the end of page 9 and the beginning of page 10: confused with the Sun) which had heen worked out by Philolaus (about 475 B.C.) within the context of the Pythagorean school.9 In a further modification of this theory the central fire as well as the hypothesis of an anti-earth were done away with, which left the earth at the center of the universe. To offset this addition, the last six lines on the bottom of page 10 should be deleted, for these lines are repeated at the top of page 11. Otherwise, with this change, the exposition reads correctly. The remaining typographical errors are few and in no case do they affect the sense. After a brief introduction in which he presents the astronomical concepts necessary for understanding the details of the Copernican debate, Fantoli divides his treatment into seven chapters. The first two of these are devoted to Galileo's early life and teaching at the Universities of Pisa and Padua, his perfection of the telescope, and the beginnings of the controversies about the earth's motion that were provoked by his telescopic discoveries, The next three chapters then take up the scriptural arguments in detail, Galileo's battle with the Jesuits over the comets of 1618 and his The Assayer of 1623, and his resumption of the Copernican program with the publication of his Dialogue...

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS The Inference That Makes Science. By ERNAN McMULLIN. The Aquinas Lecture, 1992. Milwaukee: Marquette University Press, 1992. Pp. iv +112. In this ambitious lecture Father Ernan McMullin recapitulates and refines a thesis that has guided his thought for the past forty years. In essence the thesis is this: precisely how science is made has eluded the best minds for centuries, and only in the work of Charles (...) Sanders Peirce, suitably emended by McMullin, has the puzzle finally been solved. " Retroduction " is the inference that makes science. Once this is understood, errors on what constitutes scientific method-those of Aristotle, Aquinas, Galileo, Newton, Bacon, Hume, et al.-can be rectified and one can see science for what it truly is: a complex process of theory appraisal that yields, not definitive truth, but well-established results to which assent can be given with at best "practical certainty," whatever that might be (pp. 91-96). Why McMullin should have chosen such a theme for an Aquinas Lecture is a question that defies reasonable answer. Surely one does not have to he so negative about the thought of Aristotle, Aquinas, and Galileo to advance one's ideas about science in the present day. What McMullin could easily have done, and he hints at this in the last two paragraphs of his lecture (pp. 97-98), is show how retroduction is itself simply a relaxed version of the demonstrative regress, the method actually endorsed by Aristotle, Aquinas, and Galileo. Such a retroductive version, fair enough, yields knowledge of a probable cause, the type of knowledge most typical of modern science. McMullin did not have to embark on the dangerous course of trying to prove that proof and certainty are forever beyond the grasp of science, or that never in the history of science has anyone established a definitive truth. That, in effect, is what McMullin has tried to do, and in the attempt to make the point he fumbles at almost every juncture throughout a very long lecture. To set the record straight more than a review is being re--·quested; perhaps a book, and even that might not suffice for those whose minds are made up. To understand the import of the lecture one must appreciate that it is hut a brief episode in a debate over demonstration in science that has been going on since McMullin first came to the University of Notre Dame in 1954. I myself have published many hooks and articles that engage the very point of his lecture and provide the contra evidence to 131 132 BOOK REVIEWS show elements of continuity in scientific method from Aristotle to the present. My last two volumes, in press at the same time as McMullin's Aquinas Lecture, answer in detail the aporiai he there raises.1 I need 1 Galileo's Logic of Discovery and Proof.

DordrechtBoston -London: Kluwer Academic Publishers, 1992, xix + 239 pp. only refer the interested reader to them for an extended and documented reply to his arguments. Some idea of the flavor of our debate, however, can be gained from the following. To support his thesis, McMullin has to maintain that Aristotle's proof that the moon is a sphere (from its having phases) and that Galileo's proofs that there are mountains on the moon, that Jupiter has satellites, and that Venus circles the sun (all based on telescopic observations) are not strictly demonstrative, that is, they do not yield true and certain conclusions. He declines to answer a query I have often tendered whether he personally is certain on the basis of pre-spacecraft evidence that the moon is a sphere, that there are mountains on it, that Jupiter has satellites, and so on. Instead he offers the categorical response "that planetary science is not an apodictic science, indeed that no natural science is... (shrink)

David Estlund’s Democratic Authority develops a novel doctrine of “normative consent,” according to which the nonconsent of those with a duty to consent is null. This article suggests that this doctrine can be defended by confining it to contexts involving consent to an authority, which raise distinctive normative challenges, but argues that Estlund’s attempt to deploy the doctrine fails, for it does not provide convincing reasons to think that citizens have any duty to consent. In closing, the article suggests that (...) the doctrine of normative consent might yet do some useful work in a quite different theoretical setting. (shrink)

This essay focuses on what I shall call “cosmopolitan altruism”—the motivationally effective desire to assist needy or endangered strangers. Section I describes recent research that confirms the existence of this phenomenon. Section II places it within interlocking sets of moral typologies that distinguish among forms of altruism along dimensions of scope, interests risked, motivational source, and baseline of moral judgment. Section III explores some of the relationships between altruism—a concept rooted in modern moral philosophy and Christianity—and the understanding of virtue (...) and friendship characteristic of Aristotelian ethical analysis. Finally, Section IV argues that cosmopolitan altruism does not represent moral progress simpliciter over other, less inclusive views, and that the widening of moral sympathy to encompass endangered strangers entails significant moral costs.

This book is a major contribution to the current theory of liberalism by an eminent political theorist. It challenges the views of such theorists as Rawls, Dworkin, and Ackerman who believe that the essence of liberalism is that it should remain neutral concerning different ways of life and individual conceptions of what is good or valuable. Professor Galston argues that the modern liberal state is committed to a distinctive conception of the human good, and to that end has developed characteristic (...) institutions and practices - representative governments, diverse societies, market economies, and zones of private action - in the pursuit of specific public purposes that give unity to the liberal state. These purposes guide liberal public policy, shape liberal justice, require the practice of liberal virtues, and rest on a liberal public culture. Consequently the diversity characteristic of liberal societies is limited by their institutional, personal, and cultural preconditions. (shrink)

Probabilistic support is not transitive. There are cases in which x probabilistically supports y , i.e., Pr( y | x ) > Pr( y ), y , in turn, probabilistically supports z , and yet it is not the case that x probabilistically supports z . Tomoji Shogenji, though, establishes a condition for transitivity in probabilistic support, that is, a condition such that, for any x , y , and z , if Pr( y | x ) > Pr( y (...) ), Pr( z | y ) > Pr( z ), and the condition in question is satisfied, then Pr( z | x ) > Pr( z ). I argue for a second and weaker condition for transitivity in probabilistic support. This condition, or the principle involving it, makes it easier (than does the condition Shogenji provides) to establish claims of probabilistic support, and has the potential to play an important role in at least some areas of philosophy.

Activating relevant responses is a key function of automatic processes in De Neys's model; however, what determines the order or magnitude of such activation is ambiguous. Focusing on recently developed sequential sampling models of choice, we argue that proactive control shapes response generation but does not cleanly fit into De Neys's automatic-deliberative distinction, highlighting the need for further model development.
