Finding Truth: The Study Guide Chapter 1 Question 1 Part 2

Origin of life:

Having begun to exist, and having the constants mentioned in the book and elsewhere, that means life’s origin and development are inevitable, right? Not so fast. Pearcey points out the necessity for massive amounts of information found in DNA for even the simplest life forms. Moreover, in every other experience we have had, information comes from an intelligent source.

This is a huge problem for a naturalistic explanation for the origin of life, but there are other nearly insurmountable hurdles that prebiotic chemistry must overcome before you even get to the level of DNA.

Many genes code for the production of proteins. In living systems, these proteins are formed from 20 amino acids. Amino acids form in three-dimensional shapes that form right-and left-handed structures. Those that form in living systems are left-handed (and the sugars that bind with them are right-handed.) When these same amino acids form in nature outside of living systems, or are produced in the lab, they form in equal mixtures of left- and right-handed forms. This is called a racemic mixture. In the presence of a racemic mixture, proteins cannot form. This is not merely a case that we do not know how amino acids could form proteins for the first life. It is a case where natural chemical processes prevent such proteins from forming. As Fazale Rana writes, “…without preexisting reservoirs of exclusively left-handed amino acids and exclusively right-handed sugars, the naturalistic assembly of proteins, DNA and RNA is prohibited.”[1]

Some astrobiologists (the only field of science completely devoid of data) have suggested that life could be based on some other element than carbon, such as silicon. However, as Rana points out,

Silicon belongs to the same chemical group as carbon and should display similar chemical properties, prompting some astrobiologists to propose that life could be based on this element. But while silicon does form rings and chains, these structures lack the stability and the range of complexity found in carbon-based compounds. Silicon-silicon bonds are much weaker than the corresponding carbon-carbon bonds, and unlike carbon-carbon bonds, they are susceptible to oxidation.[2]

This leaves carbon as likely the only element from which biochemistry can arise. It also explains why the search for habitable planets begins with planets that could possibly sustain liquid water, since carbon is most reactive in the same range of temperatures in which water is liquid.

Some have accused theists of appealing to “god-of-the-gaps,” saying we are invoking God to explain what we do not understand. This is not the case. We have numerous reasons to think God exists and that he has revealed himself. Part of that revelation is that he created the universe and life. Natural obstacles to undirected processes and information that requires an intelligent source are evidence that this is so.

Why You Think the Way You Do: The Story of Western Worldviews from Rome to Home by Glenn Sunshine A review

Glenn Sunshine is a Professor of History at Central Connecticut State University, while also serving on the faculty of the Centurions Program of the Colson Center, and as the faculty advisor for Ratio Christi at CCSU. He has a BA in linguistics from Michigan State University, an MA in Church History from Trinity Evangelical Divinity School, an MA in Reformation History from the University of Wisconsin-Madison and a PhD in Renaissance-Reformation History from the University of Wisconsin-Madison. As a Christian and a historian, Sunshine has a passion for helping Christians see how worldview affects culture, and vice versa.

The thesis of Why You Think the Way You Do is that the history of Western Civilization can be traced according to its changing relationship to Christianity. Moreover, the successes and failures of Western culture can be linked to its acceptance or rejection of a Christian worldview.

The book opens with an explanation of the idea of worldview, and how it affects individuals and societies as a whole. It then traces the trajectory of Western culture from the Roman Empire, its transformation by the spread of Christianity, and the periods that followed. The chapters address major periods from the Middle Ages to the renaissance, to the modern “enlightenment” era, to the post-modern period to today. Sunshine shows how changes in worldviews impacted major events such as three great revolutions in England, France and America. This section was especially helpful to understand why the American Revolution succeeded where the Glorious Revolution, and the French Revolutions failed.

As history unfolds in more recent decades, we see the consequences of elevating personal autonomy to the point where ultimate freedom for all means little freedom for some. We see where the only thing considered immoral is considering something immoral. Moreover, we see how struggles for equality have become struggles for privilege by claiming victim status. We see tolerance become meaningless since tolerance entails disagreement, but disagreement is considered intolerance.

Sunshine has painted a clear picture of the consequences of the absence of the Christian worldview in the public square. While the history of Christendom is checkered with its wars of religion, Sunshine gives fair treatment of the issue, acknowledging excesses while noting where these diverge from Christian teaching.

It is not only society, however, that has lost a conscious Christian worldview. This is also missing in much of the Church. We in the church need to read this book and take its lessons to heart if we hope to have an impact on our culture.

This book is accessible to middle-school students, while being rich enough to not bore those with advanced degrees. Church youth leaders and students would do well to study this book. Our future as a nation may well depend upon it.
