. Philosopher-theologian Bernard J. F. Lonergan defines emergence as the process in which “otherwise coincidental manifolds of lower conjugate acts invite the higher integration effected by higher conjugate forms” (Insight, [1957] 1992, 477). The meaning and implications of Lonergan’s concept of emergence are considered in the context of the problem of reductionism in the natural sciences. Examples are taken primarily from physics, chemistry, and biology.

One of Rahner's classic studies, this volume employs the German Jesuit theologian's deep understanding of the philosophy of Thomas Aquinas to explore the relationship between the spirit and matter, metaphysical and concrete realities.

Abstract In his Aquinas Lecture 1992 at Marquette University, Ernan McMullin discusses whether there is a pattern of inference that particularly characterizes the sciences of nature. He pursues this theme both on a historical and a systematic level. There is a continuity of concern across the ages that separate the Greek inquiry into nature from our own vastly more complex scientific enterprise. But there is also discontinuity, the abandonment of earlier ideals as unworkable. The natural sciences involve many types of (...) inference; three of these interlock in a special way to produce “retroductive inference,” the kind of complex inference that supports causal theory.

On the basis of his acquaintance with theoretical elementary particle physics, and following the lead of Thomas Torrance, John Polkinghorne maintains that the data upon which a science is based, and the method by which it treats those data, must respect the idiosyncratic nature of the object with which the science is concerned. Polkinghorne calls this the "accommodation" (or "conformity") of a discipline to its object. The question then arises: What should we expect religious experience and theological method to be (...) like if they are accommodated to the idiosyncratic nature of God? Polkinghorne's methodological program is typical of postcritical positions in the theology-science dialogue in holding that the fiduciary element in theological method is simply a species of the fiduciary element that is a de facto part of all knowing—in other words, theological method does not differ in fundamental kind from the methods of the natural sciences. But this program may contain the seeds of an alienation of theological method from the transcendence of God similar to the double self-alienation of theology described by Michael Buckley in At the Origins of Modern Atheism. I contend that something like Bernard Lonergan's position on how the method of faith seeking understanding is related to the methods of the natural sciences is exactly the sort of thing that one should expect on the supposition of Polkinghorne's principle of accommodation, at least if the God who is the object of theological science is transcendent. The way in which the divine differs from all other objects ought to be disclosed or reflected in religious experience and theological method. Polkinghorne charts the course for an accommodated theology, but it seems to be Lonergan who is more intent on following it. (shrink)

The notion of imagination as a specific human capacity first took shape in the works of Plato and Aristotle, and was further developed by Latin writers like Cicero and Christian theologians like Augustine. It came to be associated in a special way with the activity of poets and was celebrated as such in Dante's Divine Comedy. By the 17th century Francis Bacon could contrast science as the work of reason with poetry, the work of imagination. Yet in that same century, (...) an enlargement began of the human grasp of things very distant, very small, and long past, i.e. of things, processes, and events, entirely remote from the testimony of direct perception. This enlargement depended in the first instance on human powers of imagination, though those engaged in its pursuit were slow to recognize this, so strong was the perceived opposition between reason and imagination. Only very gradually did that opposition break down; even today, when theoretical physics depends so crucially on the construction of categories altogether distant from the familiar realm of the senses (defined here as the work of „second imagination”), science is still too often seen as the domain of rigorous method by contrast with the free-ranging territory of the poet and the artist.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. (...) And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility. (shrink)

An expanded & revised version of Religion in an Age of Science. Three new chapters on physics & metaphysics in the 18th century and biology & theology in the 19th century. Other new sections included.

The thought of Bernard Lonergan provides an epistemological position that is both true to the exigencies of modern science and yet open to the possibility of God and revealed religion. In this paper I outline Lonergan's “transcendental method,” which describes the basic pattern of operations involved in any act of human knowing, and discuss how Lonergan uses this cognitional theory as a basis for an epistemological position of critical realism. Then I explain how his approach handles some philosophical problems raised (...) by classical and modern science and show how his thought provides an intelligible link between the scientific and religious horizons.

In developing his trademark use of “consonance” to prescribe a relationship between Christian faith and the natural sciences, Ernan McMullin drew on severaldistinctly Augustinian philosophical and theological themes during his fifty years of scholarship. Particularly prominent in McMullin’s work were an emphasis placed on Augustine’s biblical hermeneutic, which prioritized both literal and non-literal interpretive techniques, and Augustine’s epistemology of divine illumination. This paper examines several elements as part of an expository account of McMullin’s contribution toward the consonance between Christian faith (...) and the natural sciences. It also outlines McMullin’s theory of retroduction and his account of scientific realism, both of which are philosophical positions that provide additional support for consonance from an epistemological perspective. I conclude that for McMullin, consonance is a differentiated term that hints at underlying metaphysical claims without necessarily delineating the nature of those claims. (shrink)

Abstract. Augustine, and following him some major theologians of the early Christian church, noted the apparent discrepancies between the first two chapters of Genesis and suggested an interpretation for these chapters significantly different from the literal. After examining a selection of the relevant texts, we shall follow the later fortunes of this interpretation in brief outline, figuring in particular an unlikely trio: Suarez, St. George Mivart, and Thomas Henry Huxley. Moral: Darwinian theory might plausibly be construed as implementing, unawares, a (...) suggestion from that other Christian tradition. (shrink)
