If A God Did Exist: The Rational Impossibility of a Knowable Deity

Where Reason Meets the InfiniteIf A God Did Exist: The Rational Impossibility of a Knowable Deity is a bold inquiry into one of the oldest and most profound questions in human thought: Can the existence of God ever be proven or even meaningfully conceived within the limits of reason and science?In this meticulously argued exploration, Dr. Robbie King dissects the boundary between belief and knowledge, tracing the edge where science must fall silent and faith begins to speak. Drawing from the legacies of Karl Popper, Ludwig Wittgenstein, Carl Sagan, Richard Dawkins, and other great minds, Dr. King shows how the principle of falsifiability — the very heart of scientific reasoning — renders the idea of a “knowable God” not merely unproven, but rationally impossible.From the philosophy of science to quantum cosmology, from the psychology of belief to the history of religion’s retreat before empirical discovery, If A God Did Exist examines with unflinching precision why the divine cannot be tested, known, or measured — and why that very unknowability defines its illusion.Yet this is not a cynical book. It is a celebration of intellectual courage — of the scientist’s humility before mystery, and the philosopher’s pursuit of clarity in a world of comforting myths. For readers of Sagan, Dennett, Asimov, or Dawkins, this book is a modern classic in rational inquiry — elegant, fearless, and transformative.About the AuthorDr. Robbie King is a clinical psychologist, aeronautical engineer, historian, scientist, economist, value investor, music composer, singer, humorist, digital artist, photographer, linguist, theologian, social critic, and multi-genre author with 105 published books.
