Long Journey Home: A Guide to Your Search for the Meaning of Life (2001) by Os Guinness is a commendable book on understanding worldview. In this book, Guinness patiently crafts an argument for understanding worldview and following them to their logical conclusions in the tradition of his mentor, Francis Schaeffer.
Guinness is encouraged by seekers after truth. Too many in modern society have set aside the pursuit of truth in "an unexamined age," distracted by things of little consequence. But throughout the ages, there are seekers after truth. He provides examples of how people have sought after meaning throughout the ages, but particularly during modernity and post-modernity. For example, he touches upon the stories of those like Foucault, Huxley, and Bertrand Russell. He carefully works to demonstrate how their worldviews essentially come to places of now satisfactory answers. He continues by showing that seekers cannot be satisfied just with seeking, but with eventually coming to the knowledge of the truth, based in evidence, which leads to commitment.
I would gladly put this book into the hands of any believer or nonbeliever. It is well-written, well-conceptualized, and non-coercively leads the reader to examine their own pursuit of meaning to its logical end (what Schaeffer called taking the roof off). If you suspect that ideas have consequences, this is the book for you.
