Known for his deeply mystical writings about Christianity, Nicholas of Cusa wrote this, his most popular work, against a backdrop of widespread Church corruption. God, he believed, is found in all things, and thus cannot be perceived by man's senses and intellect alone. The path to ultimate knowledge, then, begins in recognizing our own ignorance. Deeply influenced by Saint Augustine, Nicholas mixes the metaphysical with the personal to create a deeply felt work, first published in 1453, designed to restore faith in even the most jaded.
