Is it possible to prove the existence of God by the very act of thinking, arguing, or doubting? Can logic, morality, and rationality exist without God—or do they actually presuppose Him? In TAG: The Transcendental Argument for God , you’ll explore one of the most powerful and philosophically compelling arguments in Christian apologetics. Rooted in the thought of Cornelius Van Til and developed within the framework of presuppositional apologetics, TAG challenges every worldview at its foundation—not by appealing to mere evidence or probability, but by demonstrating the impossibility of the contrary . This book is your deep-dive into: The nature of transcendentals : truth, logic, morality, being. - Why atheism, naturalism, and pantheism cannot account for the world we live in. - How the Triune God of Scripture uniquely solves the philosophical problem of unity and diversity. - Why logic, moral obligation, and knowledge are meaningless without God . - How TAG answers objections like “Isn’t this circular?” or “Can’t I just assume logic works?” Through clear explanation, historical depth, rigorous critique of unbelieving worldviews, and formal breakdowns of the argument itself, this book defends Christianity as the only coherent and livable worldview —not just as a religion, but as the necessary foundation for thought itself . Whether you're a serious student of theology, an apologist, a philosopher, or a skeptic exploring the intellectual strength of Christianity, this book is a vital resource in understanding why denying God collapses into absurdity —and why every rational act you perform is a testimony to His existence. “The fool says in his heart, ‘There is no God.’” - Psalm 14:1 TAG shows why the fool’s position is not just wrong, it’s incoherent.
