"People of good will wish to see science and religion at peace. . . . I do not see how science and religion could be unified, or even synthesized, under any common scheme of explanation or analysis; but I also do not understand why the two enterprises should experience any conflict." So states internationally renowned evolutionist and bestselling author Stephen Jay Gould in the simple yet profound thesis of his brilliant new book. Writing with bracing intelligence and elegant clarity, Gould sheds new light on a dilemma that has plagued thinking people since the Renaissance. Instead of choosing between science and religion, Gould asks, why not opt for a golden mean that accords dignity and distinction to each realm? At the heart of Gould's penetrating argument is a lucid, contemporary principle he calls NOMA (for nonoverlapping magisteria)—a "blessedly simple and entirely conventional resolution" that allows science and religion to coexist peacefully in a position of respectful noninterference. Science defines the natural world; religion, our moral world, in recognition of their separate spheres of influence. In elaborating and exploring this thought-provoking concept, Gould delves into the history of science, sketching affecting portraits of scientists and moral leaders wrestling with matters of faith and reason. Stories of seminal figures such as Galileo, Darwin, and Thomas Henry Huxley make vivid his argument that individuals and cultures must cultivate both a life of the spirit and a life of rational inquiry in order to experience the fullness of being human. In his bestselling books Wonderful Life, The Mismeasure of Man, and Questioning the Millennium, Gould has written on the abundance of marvels in human history and the natural world. In Rocks of Ages, Gould's passionate humanism, ethical discernment, and erudition are fused to create a dazzling gem of contemporary cultural philosophy. As the world's preeminent Darwinian theorist writes, "I believe, with all my heart, in a respectful, even loving concordat between . . . science and religion."
