In this book, Louis Roy takes account of the fact that, in the last fifty years, numerous people in the secularized West have responded yes to surveys that asked, "e;Are you aware of having had an experience during which you felt in the presence of a dimension or a reality very different from ordinary human life?"e;Are such experiences mere illusions? Some thinkers, like Feuerbach and Freud, believed so. Are such experiences encounters with God? Karl Barth, a great Protestant theologian, did not think much of their worth. On this issue, psychologists and theologians are divided. Roy argues that those experiences are valid, that they possess a real potential, and that they can open their recipients to a genuine wisdom. He reports on eight narratives, spells out their constitutive elements, classifies them into four categories--aesthetic, ontological, ethical, and interpersonal--and suggests criteria to assess their concrete authenticity. Thus, this book will appeal to educated readers interested in spirituality, philosophy of religion, psychology, literature, theology, and pastoral ministry.
