Religion and Science: The Emerging Relationship
The first article in this series introduced four
basic models through which people understand the relationship between religion
and science--exploring the model of Conflict. These four models were offered by scientist
and theologian Ian Barbour. The models
This model proposes that there is no conflict between religion and science because they are two separate ways of understanding the nature of reality each with its own distinctive modes of inquiry and discourse. 1 This model results in a split personality about the nature of reality. As such, science is free to do its own work without reference to a religious vision of the reality. As a consequence, this may result in an ethical neutral approach to scientific research. On the other hand, in such a model religion goes its own way without reference to the modern scientific discovery. Religion notes that science has nothing to say about the truth claims of religion. This is especially so for those prophetic religions that originated in God’s revelation through persons and events in history.
Typical of this model is the understanding that religion and science use different language games (Ludwig Wittgenstein). Therefore, we should not expect the language used in religion to necessarily be helpful for science. Religion and science approach reality from different horizons by which each approach utilizes their own symbols and concepts to communicate the truth as each approach understands truth. It is now apparent that scientists and mathematicians have discovered that there are limits to human knowing that cannot be resolved by human investigation.
The most recent history of both physics and mathematics has produced admirable results, but it also shows fundamental limits to physical and mathematical knowledge. This must also be significant for biology, which builds on physics and mathematics, and especially for neurobiology.
· Physics came up against fundamental limits with quantum theory. The Heisenberg indeterminacy relation is one of its main principles: since the position and momentum of a particle cannot be measured at the same time, in principle certain atomic events cannot be calculated before hand. The indeterminacy allows only for statistical probability.
· Mathematics came up against fundamental limits specifically in the problems of its foundations. According to Godel’s second incompleteness theorem in 1930, no finite, constructive proofs provide a universally compelling guarantee that mathematical thought is free of contradiction. 2
As a consequence, there is some
merit in employing the
Unfortunately, the scientific creationists, to take my first example, merge science with religion by situating the biblical creation stories alongside Darwinian evolutionary theory as a competing set of scientific ideas. To a rigorous separatist, such a fusion of science and scripture not only threatens the integrity of science; what is worse, it also trivializes religion by placing sacred writings in the same genre as mundane scientific discourse. 3
Science cannot prove or disprove the claims of
religious belief because it is impossible to use the methods of science to
prove or disprove God, and the experience of God, in the experience of people
and historical events. Such experiences
are transcendent experiences not open to empirical verification or
falsification. On the other hand, the
methods of science are protected in accord with Catholicism’s insistence that
God gave us the ability and desire to know what makes this world work and to
use that for the uplift of human beings and the creation. As noted by Pope Benedict XVI in
I examined two of the four models
proposed by Ian Barbour for how religion and science relate to each other. I looked at the models of Conflict and
In this model religion and science communicate with each other in areas of investigation and experience of reality that both religion and science find intriguing. One such area of interest is what the Roman Catholic theologian, David Tracy, refers to as boundary questions. Boundary questions arise from those experiences that cannot be adequately understood or addressed by human language. Such experiences would include the mystery of death and the origins of the universe; giving rise to the questions of why evolution, why life, and why should anything exist?
Tracy also sees a religious dimension in science. He holds that religious questions arise at
the horizon or limit situations of human experience.4
Such things as anxiety and confrontation with death, as well
as joy and basic trust are examples of horizons or limit situations.
Ian Barbour notes that religion and science hold other things in common.
Science, it appears, is not objective, nor religion as subjective, as had been claimed. There may be differences of emphasis between the fields, but the distinctions are not as absolute as had been asserted. Scientific data are theory laden, not theory free. Theoretical assumptions enter the selection, reporting, and interpretation of what are taken to be data. Moreover, theories do not arise from logical analysis of data but from acts of creative imagination in which analogies and models often play roles. Conceptual models help us to imagine what is not directly observable…. Clearly, religious beliefs are not amenable to strict empirical testing, but they can be approached with some of the same spirit of inquiry found in science. 6
The method of science places emphasis on the task of verification and falsification of test results. In other words, through the use of the scientific method and critical questioning from other horizons or theoretical assumptions the data is rigorously interrogated to see if it can stand up to such a critique. A generally accepted theory becomes a paradigm or primary model when it offers the best and widest explanation of the observable phenomenon. However, when a paradigm shifts in science, or any discipline, new assumptions, models, and concepts replace or build on the previous paradigm.7 It is important to note that religious systems also undergo paradigm shifts in their journey through history. This opens up the possibility of further dialogue between religion and science as each approach comes to a greater understanding of their own discipline so that both approaches may offer this greater clarity of self-understanding to the other in order to promote more effective dialogue with the other.
Even Albert Einstein recognized that there were reasons for some type of dialogue between religion and science, recognizing that science could not offer certain answers to the most fundamental questions about being. When asked by an astounded atheist, if he were in fact deeply religious, Einstein replied:
Yes, you can call it that. Try and penetrate with our limited means the secrets of nature and you will find that, behind all the discernible concatenations, there remains something subtle, intangible and inexplicable. Veneration for this force beyond anything that we can comprehend is my religion. To that extent I am, in point of fact, religious. 8
The world renowned scientist, Werner Heisenberg, also expressed his own belief about the relationship between religion and science when he stated:
I have never found it possible to dismiss the content of religious thinking as simply part of an outmoded phase in the consciousness of humankind, a part we shall have to give up from now on. Thus in the course of my life I have been repeatedly compelled to ponder on the relationship of these two regions of thought, for I have never been able to doubt the reality of that to which they point. (Scientific and Religious Truth, 1973). 9
There are shortcomings with this model of Dialogue. Firstly, there is a tendency to gloss over the differences between religion and science. Science does have a more objective approach to its methodology. Theology has benefitted from the rigor of scientific methodology but cannot state the “case” with the same objective certainty that would not require the assent of faith. On its part, Science must beware that its discussion of reality not move over into metaphysics, making statements about absolute truth that science is incapable of making, such as those by Richard Dawkins and Christopher Hitchens.
