What might contemporary thinkers learn from prayer? The seventeenth-century French philosopher Nicolas Malebranche suggested a possibility: that prayer teaches us how to attend. This book explores the precedents of Malebranche s advice by reading John Donne s poetic prayers in the context of what David Marno calls the art of holy attention. This requires an understanding of attention s role in Christian devotion, which he provides by uncovering a tradition of holy attention that spans from ascetic thinkers and Church Fathers to Catholic spiritual exercises and Protestant prayer manuals. Donne s devotional poems occupy a unique position in this tradition. Marno identifies in them a devotional model of thinking whose aim is to experience an affect of attention. Marno s argument is framed by compelling close readings of Death, be not proud, Donne s most triumphant poem about the resurrection. Elsewhere, Marno takes up Claudius s prayer in "Hamlet" and Saint Augustine s account of attention in the "Soliloquies" and the "Confessions." The book ends with a Coda on the aftermath of holy attention in the philosophies of Descartes and Malebranche."
