America is a tapestry of diverse and often conflicting worldviews, making it challenging to engage in meaningful conversations about life's most pressing issues. Portals provides a concise exploration of seven influential worldviews that shape the American cultural landscape. Following an introductory chapter that clarifies the concept of worldview and offers practical guidance on using the book, the volume delves into in-depth examinations of historic Christianity, secular naturalism, postmodernism, Islam, Eastern religions, the New Age movement, and the Gaian worldview. The epilogue offers a forward-thinking perspective, speculating on the future trajectory of each worldview and hinting at the emergence of new perspectives that may soon redefine our understanding of the world. While primarily designed to help Christians better comprehend their neighbors, this book serves as a valuable resource for anyone seeking to bridge the gaps between disparate worldviews and gain insight into the mental frameworks of those around them.
