Costica Bradatan proposes a new way of looking at the influential 18th-century Anglo-Irish empiricist and idealist philosopher. He approaches Berkeley's thought from the standpoint of its roots, rather than from how it has come to be viewed since his time. This book will interest scholars working in a wide variety of fields, from philosophy and the history of ideas to comparative literature, utopian studies, religious and medieval studies, and critical theory. This other Berkeley read and wrote alchemical books, daydreamed of "Happy Islands" and the "Earthly Paradise" and depicted them carefully, designed utopian projects and spent years trying to put them into practice. Bradatan discovers a thinker deeply rooted in Platonic, mystical, and sometimes esoteric traditions, who saw salvation as philosophy and practiced philosophy as a way of life. This book uncovers a richer Berkeley, a more profound and spectacular one, and, it is hoped, a more truthful one.
