Book Review - Why You Think The Way You Do by Glenn Sunshine

This book addresses something I think is important to know: how the way we think has changed over the centuries right up to the present day. In fact I once fantasized briefly about writing this book myself, but the thought went away when I realized how much research I'd have to do to lay it all out correctly. Fortunately Dr. Glenn Sunshine, who as a history professor has a better background for this book anyway, had been compiling the research for a few years already and chose to put it in book form. I've gotten to know Glenn over the past couple years, and have learned to appreciate his insights as a historian, a thinker, and a Christian.

In this book Sunshine describes what the dominant worldview in the West has been, starting with the Roman Empire. He explains that the well-known decadence of the Romans, from slavery to sexual license to infanticide and more, was the result of the basic assumptions about life in the Empire. He also shows how the gradual flourishing of Christianity introduced an entirely different view of life - one based on the Bible - and how this Biblical worldview not only counter-acted many of the evils of Roman society, but became the basis for Western societies into the Middle Ages. He provides a good summary of how Naturalism (the belief that there is no God of any kind; the physical world is all that exists) became such a force in the West just in the last couple centuries, as well as explaining the popularity of postmodern thinking today.

The reason I think it's important for Christians to understand this is basically twofold. First, it helps us understand that all ideas come from somewhere: they come from a worldview. For example, the notion that science has dis-proven God's existence is a one popular today, but it's not a brute fact. Rather, it's a philosophical assumption (ie. an opinion) rooted in the Enlightenment. Learning to recognize the worldview roots of such ideas we encounter increases understanding, helping us sort out fact from opinion. Secondly, knowing why certain ideas have gained traction helps us dialogue more effectively with people who hold other, different worldviews than we do.

This book is written for the layman. It describes the flow of thought in the West for the past 2,000 years as a story, making it easier to grasp. In the process, it explains how Christianity is the foundation for virtually all of the good aspects of Western society, from human rights to science & technology, to personal liberty and representative government. And by implication then, it describes what we stand to lose if Christianity is completely dislodged from the Western worldview by Naturalism and/or postmodernism.

Along those lines, Sunshine ends the book with a list of eye-opening parallels between modern America and ancient Rome. He argues that after two millennia we have come full circle, and that the American worldview is now looking increasingly like the Roman worldview during the decline of the Empire. And he suggests several things Christians and churches can and should do about it. Worth the read.
