A cusp catastrophe: Hysteresis, bimodality, and inaccessibility in rabbit eyelid conditioning

Three properties of the cusp catastrophe: bimodality, inaccessibility, and hysteresis were evaluated in rabbit eyelid conditioning. Bimodality was evidenced by the fact that responding tended to occur at either very low or very high levels, and inaccessibility by the fact that intermediate levels of responding were rarely encountered. Hysteresis was demonstrated when: (a) levels of responding attained under a continuous schedule of reinforcement were largely maintained by a schedule which was too lean to promote conditioning by itself; and (b) levels of responding attained with a high intensity unconditional stimulus were largely maintained by a lower intensity unconditional stimulus which was too weak to promote conditioning in its own right. These results are consistent with the model of conditioning suggested by P. W. Frey and R. J. Sears (Psychological Review, 1978, 85, 321–340) which postulates response-mapping rules based on the cusp catastrophe.     

Kant's One World: Interpreting 'Transcendental Idealism'

The relationship between divine and created causality was widely discussed in medieval and early modern philosophy. Contemporary scholars of these discussions typically stake out three possible positions: occasionalism, concurrentism, and mere-conservationism. It is regularly claimed that virtually no medieval thinker adopted the final view which denies that God is an immediate active cause of creaturely actions. The main aim of this paper is to further understanding of the medieval causality debate, and particularly the mere-conservationist position, by analysing Peter John Olivi's neglected defence of it. The paper also includes discussion of Thomas Aquinas's arguments for concurrentism and an analysis of whether Olivi's objections refute his position.     

Emigration,Nationalism and Church Identity in Europe: The Legacy of the German St Raphael Society in International Catholic Migration Assistance

At the very time that historians have pin-pointed a turn to hyper-nationalism in Germany, a nationalist German Catholic association for emigrant care (St Raphael Society) started its gradual transformation into an international support network. Migration as concept and reality reminded the German Catholic nationalists that a) the nation resides outside its political borders and b) one must show empathy for all strangers in strange lands. The article situates the Society within the context of the German Caritas Association and International Catholic Migration Commission.     

Growth in agreement II: Reports and agreed statements of ecumenical conversations on a world level 1982–98∗

The French thinkers who influenced the American social activist Dorothy Day through Peter Maurin are representative of French progressive thought connected with the 1891 encyclical Rerum Novarum and its 1931 successor, Quadragesimo Anno. This article discusses the influence of Kropotkin, de Foucauld, Maritain and Mounier on Day. In France itself, this thought was often frustrated but Day provides an example of the implementation of Roman Catholic Personalism in the American setting. Day was both a popularising journalist and a tireless practitioner of the threefold platform deriving from Maurin's philosophy of Roundtable Discussion, Farming Communes and Houses of Hospitality. By the early 1950s, the tangential nature of Day's interest in the worker priest movement, when the question of its suppression had global prominence, shows that Maurin had been successful not in interesting her in his French influences for their own sake but in bequeathing to her a workable synthesis as a framework for her own efforts.     

Teaching with Complicating Views: Beyond the Survey,Behind the Pro and Con

In this article I propose a method of selecting and assigning readings in the religious studies or theology classroom, such that these readings complicate one another, rather than standing in opposition or as simple alternatives. Such a strategy emulates key pedagogical insights of twelfth‐century sentence collection, an activity at the very heart of the earliest universities in Europe. It also draws support from the theories of intellectual development advanced by William G. Perry, Jr. and the Women's Ways of Knowing Collaborative. Both precedents suggest a principle of “complicating views” that can be flexibly employed in a variety of ways and diverse pedagogical contexts, as illustrated by examples from several classes. Such strategies aim to avoid reinforcing intellectual patterns of dualism or undifferentiated relativism; instead, they attempt to promote students' ability to integrate discordant voices and to appreciate diverse points of view, while also staking their own claims relative to them.     

Cornell College: Program in Science and Religion

Cornell College in Mount Vernon, Iowa, has established a new interdisciplinary program in science and religion. One of the features of this program is an undergraduate major in science and religion that requires substantial course work in at least one of the natural sciences as well as course work in philosophy, religion, and history. As a result of a grant from the John Templeton Foundation, Cornell College will offer a special course, God and Physics: From Aquinas to Quantum Mechanics (April 1998), and will sponsor an international symposium on creation and contemporary cosmology (April 1999). Opportunities exist for interested scholars to come to Cornell as Templeton Visiting Fellows in order to participate in these activities.
