Theological Science 101 Notes 119 Bibliography 129 Index 133 Preface to the 2006 Edition Two topics are natural “frontier issues” in exchanges between science and religion. One is natural theology, the search for knowledge of God derived from general experience, based on the inspection of the world and the exercise of reason. The other topic is the doctrine of creation, religion’s claim that there is a divine mind behind the order that science discovers in nature, and a divine purpose behind unfolding cosmic history. In a variety of forms, these issues have long been on the agenda for the dialogue between science and religion, providing central topics for the interaction between these two great human quests for truth and understanding. I wrote Science and Creation to make a contribution to this conversation, and the first two-thirds of the book concentrates on these two themes. Natural theology languished for about a century after the publication of Charles Darwin’s On the Origin of Species, for that book had undermined a simple theological appeal to design in nature by showing that the origin of the functional aptness of living beings did not need to be explained by invoking the direct intervention of a divine designer. However, the second half of the twentieth-century saw a revival of natural theology in a new and significantly revised form. It was no longer presented as a kind of rival to science, claiming to give an alternative explanation of biological structures, but it sought instead to complement science by setting the latter’s insights in a more profound context of understanding. The deep intelligibility of the universe (a fact that makes science possible) and the rationally beautiful order discerned by fundamental physics (which rewards investigators ix P r e fa c e t o t h e 2 0 0 6 e d i t i o n with the experience of wonder) are features of the world too significant to be treated simply as happy accidents. Yet science itself is too narrow in its explanatory scope to be able to offer understanding of these experiences. Though they arise from the pursuit of science, their source lies beyond its self-limited intellectual horizon. The new natural theology affords a deeper insight when it affirms that the rational transparency and rational beauty of the universe are signs of the presence of the mind of that world’s Creator. Christian theology understands humanity’s scientific abilities to be an aspect of the gift of the imago dei, the image of God. Chapters 1 and 2 discuss these ideas. There are two issues referred to which have seen significant development subsequent to the original publication of the book. One is the connection between natural theology and the Hebrew wisdom literature (Deane-Drummond 2000). The other is the continuing analysis of arguments relating to the insights of the anthropic principle (for a recent account, see Holder 2004). An issue that was not on the agenda in 1988, but which has received a lot of attention in recent years, is the approach to issues of natural theology made by the proponents of the so-called Intelligent Design (ID) movement. It is claimed that at the molecular level there are biological systems that are irreducibly complex (Behe 1996), that is, they consist of a number of component parts, all of which have to be in place before the system becomes effective. Entities of this kind could not have evolved gradually through the Darwinian process of the accumulation of small differences, each of which is supposed to confer some additional functional advantage step by step. It is suggested, therefore, that these irreducibly complex systems are signs of the work of some form of designing intelligence (not explicitly identified with God in the ID literature, but that is surely the tacit underlying assumption). Adherents of ID have been criticized for disguising a theological agenda under the cloak of quasi-scientific claims. I think this criticism is unfair, since the existence of irreducible complexity is surely a scientific issue, P r e fa c e t o t h e 2 0 0 6 e d i t i o n xi and, indeed, its establishment would be a major scientific discovery. I do not think, however, that that discovery has actually been made. The analyses offered do not seem to take adequate account of the subtlety and improvisatory character of evolutionary process, in which properties developed for one purpose can be co-opted to serve as part of the response to a different set of challenges to life. Moreover, I believe that the tacit theological motivation that seems to lie beneath the ID program is mistaken. The God who is the ordainer and sustainer of nature acts as much through natural processes as in any other way, and it is an error to look for signs of the Creator’s activity only in apparent breaks in the continuity of creative process. The discussion of creation in chapters 3 and 4 emphasizes two insights, one scientific and the other theological, which have a relation of complementary consonance with each other. The discussion of chapter 3 shows how the fruitful process of the world involves at all stages of its history an interplay between “chance” (understood as happenstance, the particular historical contingency that this happens rather than that) and “necessity” (the regular order of the universe). Another way of making the same point is to recognize that situations in which true novelty emerges are always “at the edge of chaos,” regimes in which order and disorder interlace without destroying each other. Chapter 4 then interprets the resulting openness of cosmic process, leading to the unforeseeable emergence of new possibilities (such as life and consciousness), as signs of the fertility and freedom bestowed by the Creator upon creation, a world whose history has more the character of a grand improvisation than that of the performance of an already-written score. This insight corresponds to an important theological realization, very widely acknowledged in the second half of the twentieth century, that creation is an act of divine kenosis, an expression of the self-limitation exercised by love, through which the Creator allows creatures to be themselves and to make themselves (see the essays in Polkinghorne 2001). xii P r e fa c e t o t h e 2 0 0 6 e d i t i o n The discussion of these two chapters involved a very preliminary consideration of a topic taken up again in my next book (Polkinghorne 1989) and exhaustively discussed in the science and religion community in the 1990s, namely, the issue of divine action. Here I simply want to note that I have changed my mind on one point. I no longer want to insist that God never acts as a cause among causes. I have come to believe that God may choose to act as a providential cause within the open grain of nature, and I see the gracious decision to act in this way as being part of the divine kenosis involved in creation (Polkinghorne 2001, 104–5). Chapter 5 is the beginning of a process of attempting to find some way of metaphysical thinking that does not deny the integrity of creation or the psychosomatic unity of human beings, and that treats with equal weight what appear to me to be our undeniable experiences of the reality of both the physical and the mental. The quest for a dualaspect monism of this kind seems to be of the greatest importance, and I have subsequently continued to wrestle with the difficulties of the task (Polkinghorne 2000, 95–99). In our present state of understanding, I do not think that we can expect an early resolution of all perplexity. Perhaps we can take to heart a lesson exemplified many times in science, that a current lack of a fully adequate explanatory theory is no ground for the denial of the reality of experienced phenomena, nor for discouragement from the task of preliminary attempts at conceptual exploration. Chapter 6 affirms two basic convictions that undergird much of my thinking: a belief in the ultimate unity of knowledge, and a commitment to seek truth through the search for well-motivated belief. I subsequently came to call the latter approach, with its strategy of moving from experience to understanding, “bottom-up thinking.” My Gifford Lectures (Polkinghorne 1994) represent my most sustained effort to approach theology in this fashion. When I wrote this text in the 1980s, I followed what was then the P r e fa c e t o t h e 2 0 0 6 e d i t i o n xiii majority convention of using a male pronoun for God and speaking of humanity as mankind. Of course, I was never so foolish as to think that God was actually male, or that all scientists were men. Since then I have become conscious and have recognized that this former mode of discourse is inappropriate. I ask the pardon of contemporary readers for the errors of my youth. john polkinghorne Queens’ College, Cambridge December 2005 Additional Bibliography Behe, M. Darwin’s Black Box.
