What would happen if you faced your doubts, set aside your preconceptions, and decided to follow the path of truth wherever it might lead? Most people, whether believers or atheists, doggedly defend what they have always believed. Many see this as an expression of faith. Yet, there is something almost inexpressibly sad about the plight of people living out their lives in reliance upon beliefs they dare not question. Perhaps that is why many of us come to a point at which we feel compelled to pursue the truth, no matter what the implications. But even if we found the courage to embark upon such a journey, could we really find a path through the scientific, philosophical, experiential, and theological thickets that surround the great questions of life? And if we did, would we know the truth and be set free? Would we be forced to face a long-feared despair? Or would we find ourselves still staring impotently at an enigmatic universe? This is a book unlike any other. It addresses these questions with unflinching honesty, drawing evidence from a diversity of scientific fields and subjecting the competing arguments to rigorous skeptical analysis.
