As one of the greatest Christian philosophers of the twentieth century, Francis Schaeffer made it his mission to relate Christianity to the surrounding culture s worldview. His works continue to have relevance today as Christians grapple with current issues in metaphysics, morals, and epistemology. In this redesigned apologetic work, Schaeffer encourages readers to have a deeper understanding of who they are, who God is, and how they know him as they encounter the infinite-personal God who is there and is not silent.
