Last of four parts--summary of Signature in the Cell

Here is the last part of my summary of Dr. Stephen Meyer's new book, Signature in the Cell. It's a bit daunting, but he has so much good info on recent discoveries that indicate a designer behind all life. The other three parts are available here in case you want to catch up.

Another complaint about intelligent design is that it does not qualify as a scientific theory by definition. Scientific theories, according to this complaint, must explain events or phenomena by reference to natural laws alone. Science must not assume there are any seen or unseen powers that interfere with the normal working of material objects. Meyer rejects this by saying the activity of a designing intelligence does not necessarily break or violate the laws of nature. He says it is the same style of explanation as other historical scientific theories in which events are explained primarily by reference to prior events. Those who say ID does not qualify as a scientific theory generally argue that it invokes an unobservable entity, it is not testable, it does not explain by reference to natural law, it makes no predictions, it is not falsifiable, it cites no mechanisms, and it is not tentative. But Meyer indicates that many scientific theories infer unobservable entities, causes, and events. For example, there are theories of chemical evolution and the existence of many transitional intermediate forms of life. Both of these are unobservable. Historical sciences commonly use indirect methods of testing as they weigh competing unobservable events to determine which one has the greatest explanatory power. The theory of intelligent design is subject to empirical testing and refutation. Many times scientists say that a theory must explain all phenomena by reference to purely material causes, but Meyer wonders why science should be defined that way. Scientists in the past have not always restricted themselves to naturalistic hypotheses. Today many scientific fields currently suggest intelligent causes as scientific explanations – consider archeology, anthropology, forensics, astrobiology.

Meyer spends time refuting the idea that intelligent design is religion. Religions usually involve various formal structures, practices and ritualistic observances, but these are all missing in ID. In addition, it does not offer a comprehensive system of belief about the intelligence behind the design of the universe. The theory of intelligent design does not affirm any sectarian doctrines. Of course this theory has religious and metaphysical implications, but these are not grounds for dismissing it. Intelligent design is not the only idea that has metaphysical or religious implications. Consider Darwinism – it has significant metaphysical and religious implications as well. Scientific theories should be evaluated on the evidence rather than the implications they may have. Antony Flew, a well-known atheistic philosopher who has now become a proponent of intelligent design, insists that we should “follow the evidence wherever it leads.” Meyer argues that the motivations of the people behind the theories should not invalidate them either because it is not the motivation that determines the merits of the idea; it’s the quality of the arguments and the relevance of the evidence marshaled in support of that theory.

Meyer ends his book by explaining why this issue matters. The scientific case for intelligent design poses a serious challenge to the materialistic worldview so dominant today in the West. Materialism may seem liberating, but it has proven “profoundly and literally dispiriting.” It suggests we have no purpose in life, we are all accidents, nothing lasts beyond the grave, everything will be gone as the universe spins down to heat death. On the other hand, intelligent design says that the ultimate cause of life is personal, suggesting there is something beyond this life.

I spent a long time going through Signature in the Cell because I like wrestling with interesting concepts. I was only able to scratch the surface of the book’s content in this summary, but my goal was to pass along the main points I got and to arouse your curiosity to know more about this fascinating field of study.
