We all have one life to live, and gradually realise that it passes quickly. As adults we learn the value of living intelligently and intentionally. Yet most of us become swamped when we try to apply this approach to the big questions of life. The biosphere and humanity are highly complex, and the cosmos is breathtakingly vast. WHAT IS TRUTH? Can we rely on perspectives that were taught to us as facts? Does current mainstream science provide all the answers and worldview we need in order to live and thrive? Can it fully satisfy our desire for meaning? This book begins with an examination of truth itself, and suggests ways we can improve our ability to discern truth from fiction. It then goes on to identify recent scientific discoveries that challenge conventional thinking, before exploring a number of other vital issues that touch on 'the meaning of life'. Is It Time to Think Again? is both a roadmap and travel-guide for people who seek to explore the big questions of life.
