Delineates the knowable from the unknowable in philosophy, science, and theology.Offering readers much to ponder, Richard H. Jones approaches the "big questions" of philosophy such as the nature of reality, consciousness, free will, the existence of God, and the meaning of life not by weighing the merits of leading arguments in these debates, but instead by questioning the extent to which we are even in a position to answer such questions in the first place. Regardless of continuous technical and even groundbreaking advances in knowledge, there will always be gaps in what we can fully understand. Distinguishing true mysteries from problems yet to be solved but within the scope of our intellectual grasp, Jones provides a penetrating and high-level overview of the scope and limits of scientific and philosophical inquiry.
