Paley’s Analogy Revisited

2009 will mark the 150th Anniversary of the publication of Charles Darwin’s book “On the Origin of Species by means of Natural Selection”, so you can expect to hear a few addresses on the topic of Darwinism over the next year or so. Darwin’s theory has rightly been labelled revolutionary; it has changed our perception of the world. Many people believe that Darwin’s theory provided the final nail in the coffin of religion, the first nails having been forged when the Bible was subjected to critical study. Critical study of the Bible revealed this book to be a library written over time rather than a single book containing the revealed word of God. The revolution in scientific thinking initiated by Darwin’s theory is an ongoing process; it has opened new doors of enquiry and it also contradicts many of our deeply cherished ideas of the nature and origin of humanity,
One of the distinguishing features of humans is our amazing curiosity. We have a need to understand the world we inhabit; at about three years of age children begin to ask questions why? and how? As a species we never lose this curiosity and when our basic needs for food and shelter are met we expand our energies thinking about and exploring the universe.
The really big questions have always intrigued us. We want to know where and how the universe originated, what it is made of, how it all works and, most importantly, what is the place of humanity in the overall scheme of things. In the western tradition, the biblical account of creation was the generally accepted orthodoxy until the enlightenment. Of course there are still seemingly intelligent people who argue on behalf of its truth but we won’t concern ourselves with them today. The Bible account of creation is remarkably similar to other accounts of creation. Most accounts of creation have in common the theme that God created the world by establishing order out of seeming chaos.
In all religious traditions humans are accorded a different status than all other living creatures. In Western belief systems humans alone are destined to survive physical death in some form or other to have a judgement made of how they lived their lives and to be rewarded or punished in accordance with the judgment. In eastern traditions human life is accorded a unique status - enlightenment can only be achieved in the course of a human life.
Great thinkers of all ages have proposed explanations about the nature and origin of the earth and the heavens. Many of these explanations have survived: Aristotle, Ptolemy, Galileo, Copernicus etc. With the benefit of hindsight we can see the flaws in these theories, but at their time they did offer a reasonable and acceptable description of the world and the place of humans in it.
Despite the differences in scientific theories, until relatively recently, few if any ordinary people questioned the actual existence of God – whether the Universe had the earth or the sun at its centre was a matter to be questioned; whether the earth and the heavens were of similar materials could be questioned- but that God instigated and oversaw the Universe was not seriously questioned; certainly not by the ordinary citizen. Philosophers and writers made many attempts to provide proof of the existence of God. Some of these arguments used to prove the existence of God fall into the category called “Argument from Design”. Humans looking at the universe are called to wonder at its physical beauty; they are amazed at its complexity, and stunned by the beauty of a starlit night. With the development of the telescope and the microscope the world was shown to be more complex and varied than previously appreciated. Science showed that instead of the heavenly bodies being fixed, some of them moved. The microscope showed the existence of an infinity of minute living creatures. Simply looking at the world calls us to wonder; and science in the enlightenment told us that our world was in fact more amazing than humans had thought. One writer who supported the idea that the existence of God could be proved by the argument from Design was William Paley. In 1802 he published his book “Natural Theology” which would have been required reading for Charles Darwin when he was a student of Theology at Cambridge.
In his book Paley uses a watch as an analogy to argue for the existence of God as the creator or designer of the Universe. Readers are invited to imagine finding a watch; in 1802 the watch would be mechanical; all the parts of the watch must fit together with precision and to work together in order to fulfil its function of telling the time. For Paley is it inconceivable that something as complicated as a watch could accidently fit its parts together and then begin to work correctly. The watch must have had a designer, this designer would need a mind of great intelligence and creative imagination to conceive the idea and to bring it to fruition. In comparison with the Universe a watch is a relatively simple mechanism. When we consider the amazing size, complexity, variety of life forms and beauty of the Universe, we can see that it is infinitely more complex than a watch. So argues Paley the Universe must also have had a designer/creator and this creator must have a mind of infinite intelligence and creativity; and a creator with such extraordinary power is indeed God.
William Paley’s argument for the existence of God is intuitive, simple and appealing. The natural world does seem to provide abundant evidence of a wise and benign designer; many people gaze at the beauty of the earth and are drawn to awe and wonder; for some people the beauty of nature confirms their belief in God .
Darwin himself was persuaded by Paley’s argument until he developed his theory of survival by means of natural selection. In his autobiography Darwin wrote: “The old argument from design in nature, as given by Paley, which formerly seemed to me so conclusive, fails, now that the law of natural selection has been discovered” (Charles Darwin in de Beer (1974), p50)
Darwin’s theory was often summed up or dismissed as saying at that “humans are descended from the apes”, but it is much much more subtle than that. It denies one of humanities oldest myths about God. “God” did not need to impose order on a chaotic universe, the reverse is if fact true. Out of the simplest life forms our complex, amazing universe developed. But there can be no doubting the truth of Darwin’s theory; one hundred and fifty years of scientific research and the discovery of DNA confirms the truth of Darwin’s theory, and rather than being the pinnacle of God’s creation we know that humans are also part of this evolutionary process. Modern science confirms Darwin’s theory; human and animal genes are very closely related. So have we lost one of the planks we have used in constructing an argument for the existence of God?
Richard Dawkins writing of William Paley is very blunt:
A true watchmaker has foresight, he designs his cogs and springs, and plans their interconnections, with a future purpose in his mind’s eyes. Natural selection, the blind unconscious automatic process which Darwin discovered, and which we now know is the explanation of the existence and apparently purposeful form of all life, has no purpose in mind. It has no plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of watchmaker in nature, it is the blind watchmaker.

What a put down for the gentle Mr Paley!

Scientists have still not provided a convincing theory of how the initial process of life on earth began. How or what caused inanimate objects to come to life and to be able to reproduce? I can accept that something we call “God” provides the explanation. I find no contradiction between Darwin’s theory and the idea that God instigated the process and that it is developing according to God’s design. This explanation is accepted by most Churches. I may find it difficult to let go of the idea of the existence of what we call “God”.
To-day I want to make another pitch on behalf of Mr. Paley’s type of analogy; and this is not just wishful thinking on my part; it has its basis in science. Astronomers and physicists have lately come up with indications that appear, on the surface at least, to argue towards a Mind that has arranged things – a Designer. This explanation requires that we go further back in time to before the beginnings of any life forms; to the actual moment of the Big Bang. If the force of the explosion of the Big Bang had been any greater, the matter of the Universe would have dispersed before the stars and planets could have formed. If it had been less violent, the universe would have re-collapsed into a Big- Crunch before life on the planets could have developed in a way that they could sustain life. The force of the explosion of the Big Bang had to be very precise. Obviously the precise conditions required were met – the Universe does exist. Scientists are agreed that the conditions needed for the Universe to form were within a very narrow band – any slight deviation and the Universe would not have formed.
Secondly the Big Bang produced two chemical elements – hydrogen and helium- and these elements needed to be fused together in order to produce carbon. It is when astrophysicists examine the conditions under which the carbon syntheses had to take place they discover just what a knife- edge situation it was. The smallest change in any of the constraints and our Universe would not have formed. The conditions required had to be right with a remarkable precision. If there are any scientists among you who disagree with my presentation of these scientific process I will refer you to my Open University Course. I am willing to take their word that it is truly amazing that our Universe exists. It is such an amazing thing that it is difficult for me to accept that it was all just accidental and pointless. Some people find Darwinian explanations of the origins of the universe to be bleak; that in some way they reduce the value of creation; or take away the magic. I find the opposite; that real scientific explanations of what was needed to make our Universe are more amazing and impressive than the poetical version contained in the Bible.
I am aware that scientific research is an ongoing process and even now that scientists are searching for answers to explain what seems to be a truly amazing mystery. Perhaps in 150 years some Richard Dawkins will have an equally acerbic put down for this latest argument from Design! Some scientists posit the theory that rather than being unique, our Universe may be just one of an infinite number of universes in existence. With the current level of knowledge the idea of an infinite number of universes seems somewhat unbelievable but who knows? Time and science will give us answers to these questions but probably not in our lifetime. We have to live with incomplete information.
We come to our religious beliefs based on present knowledge, on our experience and perhaps to some extent on our needs. Some of us find it difficult to accept a world without any seeming purpose. A belief in God or that there is an ultimate purpose to life is very comforting. Religious beliefs are not something that can be acquired at will; the validity of religious belief is not something that can be proved to be correct. At the end of the day it is a matter of faith. Faith is described as belief without supporting evidence; a difficult idea for most Unitarians.
If we are seeking evidence for the existence of God we will not find it from any external source. Faith in the existence of God can only be found internally. Before space exploration it was easy to imagine God as some human like entity, residing somewhere in the heavens in control of the world. But that God is a human construct; it is humans inventing God according in our own image and likeness. We should change the word God, I believe that what we call God is things like love, compassion, sharing, community, it is to be found in silence and in living thoughtfully and living in balance with nature and all living beings.
If we try to prove the existence of God we are doomed to failure. Those who hold an unshakable belief in something that they call God have come to that position through their experience. Through meditation, prayer and reflection. What they have experienced has enhanced their lives and that is something that has real value.
Amen
