Robert John Russell: Ian Barbour's Methodology in Science and Religion
During the past half century of its inception and flourishing, the question of method lies at the heart of the theology and science community: how are we to relate these two disparate fields? I will take the question as broadly including issues in epistemology, the nature of scientific and religious language, as well as issues in theory construction, choice and defense.
We will find that the contributions by Ian G. Barbour to method dating back to the 1960s form the initial bridge, to use my favorite metaphor for it, across which so much traffic now flows and in both directions according to my extension of his work which I call ‘creative mutual interaction’ (CMI) and that his contributions to method have continued up through the present discussion to be of pioneering and critical value. Barbour called his method critical realism, a phrase taken up by almost all of the scholars who have adopted, adapted, extended, and critiqued Barbour’s methodological bridge.
1. Critical realism: Barbour’s original ‘bridge’ between science and religion.
In his ground-breaking 1966 publication, Issues in Science and Religion, Ian G. Barbour laid out a series of well-crafted arguments involving issues in epistemology (the kinds of knowledge we have), language (how it is expressed), and methodology (how it is obtained and justified). Together these arguments provide what I call the ‘bridge’ between science and religion. More than any other scholar’s work, these arguments, in my opinion, have made possible the developments of the past five decades. Barbour has explored these arguments in detail since then, principally through his 1990 Gifford Lectures, together with their revisions in 1997 and 2000.
From the outset, Barbour used the term critical realism to stand for the specific set of arguments he first developed in 1966. Most scholars in the field have adopted and developed the term, although some, while sharing one or more of its arguments, have moved away from the term (as we shall see below). Barbour viewed critical realism as an alternative to three competing interpretations of scientific theories: (1) classical or naive realism: scientific theories provide a ‘photographic’ or literal representation of the world; (2) instrumentalism: scientific theories are mere calculative devices, and (3) idealism: scientific theories depict reality as mental. Instead, from a critical realist perspective, scientific theories yield partial, revisable, abstract, but referential knowledge of the world. Linguistically, scientific theories are expressed through metaphors and models which ... selectively represent particular aspects of the world for specific purposes... (They) are to be taken seriously but not literally. Scientific models are thus systematically developed metaphors. Turning to religion, he defined ‘metaphor’ similarly as an open-ended analogy. Although more than a useful fiction, the meaning of a religious metaphor cannot be reduced a set of literal statements.
Barbour then turned to the then current discussion of scientific methodology, with major breakthroughs by such philosophers of science as N. R. Hanson, Gerald Holton, Thomas Kuhn, Michael Polanyi, Steven Toulmin, and Imre Lakatos. He began with the empiricism of Carl Hempel, whose ‘hypothetico-deductive’ method brought together inductivist and deductivist approaches to the construction and testing of theories vis. Popperian falsificationism. In the 1960s, this method was fundamentally recast. It was then seen to operate within both the historicist and contextualist elements which characterize the scientific community. These elements include the ‘theory-laddenness of data’, the role of intersubjectivity rather than strict objectivity in scientific rationality, the way science is structured through paradigms and the revolutions in such paradigms in the history of science, the presence of metaphysical assumptions about nature in scientific paradigms, and the role of aesthetics and values in theory choice. Scientific theories, while referring to the world and conveying truths about it, are a human construction and their conclusions are inherently tentative and subject to revision. Nevertheless, according to Barbour, they are to be assessed by four criteria which are reasonably trans-paradigmatic and undergird their objectivity: agreement with data, coherence, scope and fertility.
Barbour used these criteria to articulate what he called a critical realist theory of truth. Like classical realism, the meaning of truth in critical realism is correspondence with reality (i.e., reference) and the key criterion of truth is agreement of theory with data. But we often have only indirect evidence for our theories; moreover, networks of theories are tested together. Thus internal coherence and scope also serve as criteria of truth, as stressed by rationalists and philosophical idealists. Even this is insufficient when competing theories are equally coherent and comprehensive; hence fruitfulness serves as a fourth criterion of truth, as pragmatists, instrumentalists and linguistic analysts stress. Thus intelligibility and explanatory power, and not just observableness or predictive success, is a guide to the real.
Turning to philosophy of religion, Barbour constructed a similar defense of critical realism. Here his sources in religious epistemology, methodology and language include the writings of John Wisdom, John Hick, Ian Ramsey and Frederick Ferré. With these arguments in place, Barbour was prepared to make his crucial, methodological claim that, in my term, ‘bridges’ science and religion: the basic structure of religion is similar to that of science in some respects, though it differs at several crucial points.
Similarities: Both science and religion make cognitive claims about the world using a hypothetico-deductive method and a contextualist and historicist framework. Both communities organize observation and experience through models seen as analogical, extensible, coherent and symbolic, and these models are expressed through metaphors. Differences: But there are important differences in the ‘data’ of religion compared to that of science. Religious models serve non-cognitive functions which are missing in science, such as eliciting attitudes, personal involvement and transformation. Moreover, compared to science, where theories tend to dominate models, in religion models are more influential than theories. Religion lacks lower-level laws such as those found in science, and the emergence of consensus seems an unrealizable goal. Religion also includes elements not found in science such as story, ritual, and revelation through historical events.
Barbour’s argument culminates in his use of paradigm analysis to place science and religion on a continuous spectrum in which both display „subjective’ as well as ‘objective’ features, though the former are more prominent in religion and the latter in science. The subjective features include the influence of theory on data, the resistance of comprehensive theories to falsification, and the absence of rules for choice among paradigms. Objective features include. It is the dynamic tension between similarities and differences, and between subjective and objective features in both science and religion, that together make Barbour’s analysis so original and fruitful.
2. Further developments of critical realism in theology and science
Barbour’s arguments have been developed in significant and diverse ways by a variety of scholars. In his 1979 Bampton Lectures and in his 1983 Mendenhall Lectures, Arthur Peacocke endorsed critical realism in both science and religion. In his 1993 Gifford Lectures Peacocke acknowledged the diversity of positions held by scientific realists but argued for a „common core“ of claims: that scientific change is progressive and that the aim of science is to depict reality. Peacocke made a similar case for critical realism in theology: As in science, theological concepts and models are partial, inadequate, and revisable, and, unlike those in science, they include a strong, affective function. Still Peacocke views them as (the) necessary and, indeed, the only ways of referring to ‘God’ and to God’s relation with humanity, though he stresses that referring to God (e.g., the via positiva) does not mean describing God (the via negativa). Its grounding in a continuous community and interpretive tradition make it „reasonable“ to accept theology’s explication of religious experience, though metaphorical and revisable, as an inference to the best explanation.
According to John Polkinghorne, critical realism is the best explanation of the success of science, the only philosophy adequate to scientific experience, and the view most congenial to scientists themselves. In his 1994 Gifford Lectures, Polkinghorne drew on Thomas Torrance and Polanyi in highlight the doubly circular character of knowledge: belief and understanding are mutually entailing, and what is known and the knowledge of it are mutually conforming. Scientific theories are shaped by the way things are, offering an ever increasing degree of verisimilitude as suggested by his motto, „epistemology models ontology.“ Polkinghorne offers similar arguments for theology, too.
3. The importance of Lakatos in theology and science
Barbour was the first scholar in the field to discuss the potential importance to theology of the writings of Imre Lakatos in the philosophy of science. Since then Lakatos’ ideas have been extensively discussed by Nancey Murphy and Philip Clayton.
Murphy’s arguments arose in 1990 through her criticism of Wolfhart Pannenberg’s methodology. Pannenberg uses Stephen Toulmin’s claim that theories in history, science, and hermeneutics serve as explanations by placing facts in a broader context. For theology, the explanatory context becomes the whole of reality, including the future. In place of Toulmin, Murphy urges us to adopt the work of Lakatos, with its view of scientific theories as structured by a central core and a surrounding belt of auxiliary hypotheses. Following Lakatos, we should judge the relative progress or degeneration of such research programs on the basis of their ability to predict and corroborate novel facts.  Murphy then offers a crucial modification of Lakatos’ conception of ‘novel facts’: „A fact is novel if it is one not used in the construction of the theory T that it is taken to confirm... (that is) one whose existence, relevance to T, or interpretability in light of T is first documented after T is proposed.“ This modification allows Murphy to apply Lakatos’ methodology to theology, to decide rationally which theological research programs are empirically progressive, and thus to complete the argument for the scientific status of theology.
Philip Clayton has also advocated the theological appropriation of Lakatosian methodology. Clayton views „explanation“ as the key concept embracing both the natural and social sciences and, ultimately, theology. In the natural sciences, where one interprets physical data, the truth of an explanation is pivotal. In the social sciences, however, where one interprets both physical data and the experience of actor-subjects (i.e., the „double hermeneutic“), explanation means „understanding.“ Theological explanations, then, are subject to validation not by verificationist standards, but by intersubjective testability and universalizability, as performed by the disciplinary community. The key, though, is Lakatos’ requirement that a previously specified set of criteria is held by the community by which competing explanatory hypotheses can be assessed, including the stipulation of „novel facts“.
Murphy’s approach has been implemented in discussions of theological anthropology by Philip Hefner, pragmatic evaluation of religion by Karl Peters, and the theological implications of cosmology in my work. I believe that further pursuit of the suggestions by both Murphy and Clayton is an extremely important task at the frontiers of theology and science today.
4. Key critiques by social constructivists and feminists
Even while Barbour was developing this position, scientific realism was being challenged in a number of ways. Feminists critiques of science have stressed the crucial role of gender analysis in uncovering distortions in scientific research. According to Evelyn Fox Keller and Helen E. Longino, the roots of the feminist critique lie in externalist arguments of Kuhn but the focus is on the novel concept of ‘gender’ as the social constitution of ‘masculine’ and ‘feminine’ applied independently of the biological categories of male and female. Early feminists sought a ‘gender-free’ science by urging greater access for women in science education and research. More recent writings have used the concept of gender to analyze the content and practice of science, to detect the distortions introduced by gender bias, to uncover the sexual metaphors used for nature that legitimate dominance over nature.
Barbour’s assessment of these diverse externalist accounts is that they provide a „valuable corrective“ to the internalist view, particularly regarding the context of discovery. However, the appeal to interests is hard to document, the shift towards relativism „...underestimates the constraints on theories by the data“ and testing of theories reduces distortions due to ideologies and interests. He agrees with feminists in their challenge of dualist thought and the pervasive role of values and interests in scientific inquiry, but he calls for a rejection of dualism and not their inversion.
I would add a concern for what can be called a „feminist critique of science and religion.“ Margaret Wertheim, for example, has argued for a parallel between the marginalization of women in religion and in physics. Historically women were excluded from European universities, and thus from participating in the rise of science. Today, „the struggle women have faced to gain entry into science parallels the struggle they have faced to gain entry into the clergy.“ Wertheim advocates instead „a culture of physics that would encourage both men and women to pursue different kinds of goals and ideals...more concerned with human beings and our needs.“ I believe that a sustained focus on issues of gender as a clue to how scientific and theological voices have influenced --- and distorted --- each other and the inclusion of womanist, mujerista, and other womens’ voices will mark an important new development in „science and religion’.
5. An interaction model of theology and science
A major challenge continues to be whether science and theology be genuinely interactive, each offering something of intellectual value to the other, or is the theological role one merely of hermeneutics? In recent writings, I have explored the possibility that theology can, at least in some cases, lead to creative suggestions for scientific research which science would find beneficial as judged by it own, independent criteria in what I call the method of ‘creative mutual interaction” (CMI).
My proposal combines the depiction of the sciences and humanities (including theology) as ordered in an epistemic hierarchy, as proposed by Peacocke and by Murphy, with Barbour’s proposal of an analogy between theological and scientific methodologies. The result is striking: we can identify a number of distinct ‘paths’ between theology and science. Five paths move upwards as influences by science on theology, while three paths move downwards conveying suggestive ideas for research programs in science from theology. I believe that each path represents what has actually happened historically and what happens, though often unacknowledged, in current research. By reflecting on all eight paths together we can discern something about the interaction of theology and science as a whole, something which we have not appreciated by taking each path separately. The overall perspective might also tell us something about the direction for ‘theology and science’ in the future.
6. Summary of the status of critical realism and open issues
Over the past five decades, the predominant school of thought among scholars in theology and science, particularly of those coming from a liberal Anglo-American theological perspective, has been critical realism. The term stood for a ‘packaged deal’ whose elements were brought together from a variety of various philosophical contexts, as discussed above. Each of these elements, of course, raised complex issues that were highly debated. Still there was sufficient agreement for these elements to form what can be called the ‘consensus view’ in theology and science since the 1960’s. For these scholars, critical realism was seen as providing the crucial ‘bridge’ between theology and science, making possible real dialogue and growing interaction.
During this period, however, each of these elements has come under criticism. Some scholars have stressed the difficulties facing a realist interpretation of fundamental scientific theories, such as quantum mechanics, as well as key theological terms, such as the concept of God. Some have acknowledged the diversity of realist positions taken by philosophers as well as the continuing challenge to realism by the sociology of knowledge. Some have given increased attention to the diversity of models of rationality and their relative appropriateness for „science and religion’ and the importance of pragmatic differences, as well as similarities, between theology and science. Some have argued that critical realism is an unworkable „middle ground’ between naïve realism and relativistic interpretations such as the strong program in science. Others have argued for a ‘constructive-critical realism’ which emphasized the role of the subject especially in relation to the humanities. Some have moved to a non-foundationalist epistemology, either keeping correspondence and referentiality or shifting to a pragmatic theory of truth. Some working with an all-embracing philosophical system, such as Whiteheadian metaphysics, have developed a broad set of theological positions in light of science, while others who make more limited use of metaphysics have developed equally broad theological arguments. Other positions have emerged at increasing distances from the ‘consensus view’. For some, a post-modernist view offers an attractive approach, and for growing numbers, feminist critiques of science are crucial. Some have abandoned realism as a whole while still finding elements of the preceding still helpful in relating science and religion.
On balance, though, critical realism, as originally constructed by Barbour five decades ago, has continued to be defended, deployed and diversified widely in theology and science, and it continues to be presupposed by both most working scientists, by many theologians, and in much of the public discourse about both science and religion. On balance I believe it to be of enduring importance, both for its crucial role in the historical developments of the past decades and as a point of departure for future research. Surely Barbour’s proposal constitutes the key methodological contribution that the ‘first generation’ gave to make discourse regarding theology and science possible today.
