Apologiaway: What is the Teleological argument for the existence of God?

Answer: The word teleology comes from telos, which means “purpose” or “goal.” The idea is that it takes a “purposer” to have purpose, and so, where we see things obviously intended for a purpose, we can assume that those things were made for a reason. In other words, a design implies a designer. We instinctively make these connections all the time. The difference between the Grand Canyon and Mount Rushmore is obvious—one is designed, one is not. The Grand Canyon was clearly formed by non-rational, natural processes, whereas Mount Rushmore was clearly created by an intelligent being—a designer. When we are walking on a beach and find a wristwatch, we do not assume that time and random chance produced the watch from blowing sand. Why? Because it has the clear marks of design—it has a purpose, it conveys information, it is specifically complex, etc. In no scientific field is design considered to be spontaneous; it always implies a designer, and the greater the design, the greater the designer. Thus, taking the assumptions of science, the universe would require a designer beyond itself (i.e., a supernatural designer).

The teleological argument applies this principle to the whole universe. If designs implies a designer, and the universe shows marks of design, then the universe was designed. Clearly, every life form in Earth’s history has been highly complex. A single strand of DNA equates to one volume of the Encyclopedia Britannica. The human brain has approximately 10 billion gigabytes of capacity. Besides living things here on Earth, the whole universe seems designed for life. Literally hundreds of conditions are required for life on Earth—everything from the mass density of the universe down to earthquake activity must be fine-tuned in order for life to survive. The random chance of all these things occurring is literally beyond imagination. The odds are many orders of magnitude higher than the number of atomic particles in the whole universe! With this much design, it is difficult to believe that we simply an accident. In fact, top atheist/philosopher Antony Flew’s recent conversion to theism was based largely on this argument.

In addition to demonstrating God’s existence, the teleological argument exposes shortcomings in the theory of evolution. The Intelligent Design movement in science applies information theory to life systems and shows that chance cannot even begin to explain life’s complexity. In fact, even single-celled bacteria are so complex that, without all of their parts working together at the same time, they would have no survival potential. That means those parts could not have developed by chance. Darwin recognized that this might be a problem someday just by looking at the human eye. Little did he know that even single-celled creatures have too much complexity to explain without a creator!

The Teleological Argument

This second argument for the existence of God addresses the order, complexity, and diversity of the cosmos. “Teleological” comes from the Greek word “telos,” which means “end” or “goal.” The idea behind the argument is that the observable order in the universe demonstrates that it functions according to an intelligent design, something undeniable to an open-minded, intelligent being. The classic expression of this argument is William Paley’s analogy of the watchmaker in his book Evidences. If we were walking on the beach and found a watch in the sand, we would not assume that it washed up on the shore having been formed through the natural processes and motions of the sea. We would rather naturally assume that it had been lost by its owner and that somewhere there was a watchmaker who originally designed and built it with a specific purpose in mind. Intelligence cannot be produced by non-intelligence any more than nothing can produce something. There is, therefore, an eternal, necessary intelligence present and reflected in the space-time universe.

Until about five hundred years ago, humanity had no difficulty in acknowledging God as the Creator of the natural order. The best explanation saw Him as the divine Designer who created it with a purpose and maintained all things by the word of His power (Hebrews 1:3; Colossians 1:17). But the rise of modern science initiated a process we could call the “demythologizing of nature,” the material world. Superstition and ignorance had ascribed spirit life even to forest, brook, and mountain. Things not understood scientifically were routinely accepted to be unexplained, supernatural forces at work. Slowly, the mysterious, spiritual factor was drained away as scholars and scientists replaced it with natural explanations and theories of how and why things actually worked. After Copernicus, human significance diminished in the vastness of the cosmos, and it was felt only time and research, not God, would be needed to finally explain with accuracy the totality of the natural order. The idea of a transcendent One came to be deemed unnecessary, having been invalidated by the new theory of natural selection.

Ironically, the same science which took God away then, is bringing back the possibility of His existence today. Physics and quantum mechanics have now brought us to the edge of physicality, to a place where sub-atomic particle structures are described by some as spirit, ghost-like in quality. Neurophysiologists grapple with enigmatic observations suggesting that the mind transcends the brain!

Through the telescope it becomes more difficult in the light of experimental science to hold to the old premise that such order and complexity are the products of blind chance. The old naturalistic assumptions are being critically reexamined, challenged, and found to be unconvincing by many of today’s scientists. Dr. Walter Bradley, Professor Emeritus of Mechanical Engineering at Texas A & M University states the case: Psychology has developed an entirely new branch of study (parapsychology) which asserts that psycho-spiritual forces (ESP, biofeedback, etc.) actually function beyond the physical realm. Molecular biologists and geneticists, faced with the highly-ordered and complex structures of DNA, ascribe a word implying “intelligence” to the chaining sequences: the genetic “code.” And we have already concluded that astrophysicists have settled on the “big bang” which seems to contradict the idea that matter is eternal, and, huge as it is, the universe appears to be finite. Whether we look through the microscope or “Discoveries of the last half of the 20th century have brought the scientific community to the realization that our universe and our planet in the universe are so remarkably unique that it is almost impossible to imagine how this could have happened accidentally, causing may agnostic scientists to concede that indeed some intelligent creative force may be required to account for it.
