"A fascinating, lyrical book... Reisman's experiences in other cultures bring a richness and depth to The Unseen Body. The way he thinks about the body and medicine—the rivers and tributaries, the flowing and unclogging, the top-down organization of the brain—is extraordinary!" —Mary Roach In this fascinating journey through the human body and across the globe, Dr. Reisman weaves together stories about our insides with a unique perspective on life, culture, and the natural world. Jonathan Reisman, M.D.—a physician, adventure traveler and naturalist—brings readers on an odyssey navigating our insides like an explorer discovering a new world with The Unseen Body. With unique insight, Reisman shows us how understanding mountain watersheds helps to diagnose heart attacks, how the body is made mostly of mucus, not water, and how urine carries within it a tale of humanity’s origins. Through his offbeat adventures in healthcare and travel, Reisman discovers new perspectives on the body: a trip to the Alaskan Arctic reveals that fat is not the enemy, but the hero; a stint in the Himalayas uncovers the boundary where the brain ends and the mind begins; and eating a sheep’s head in Iceland offers a lesson in empathy. By relating rich experiences in far-flung lands and among unique cultures back to the body’s inner workings, he shows how our organs live inextricably intertwined lives—an internal ecosystem reflecting the natural world around us. Reisman offers a new and deeply moving perspective, and helps us make sense of our bodies and how they work in a way readers have never before imagined.

The heart has consistently captured the human imagination. It has been singled out as a cultural icon, the repository of our deepest religious and artistic impulses, the organ whose steady functioning is understood, both literally and symbolically, as the very life force itself. The Sublime Engine will explore the profound sense of awe every person feels when they ponder the miracle encased within their ribs. In this lyrical history of our most essential organ, a critically-acclaimed novelist and a leading cardiologist--who happen to be brothers--draw upon history, science, religion, popular culture, and literature to illuminate all of the heart's physical and figurative chambers. Each of the four sections-- The Ancient Heart, The Renaissance Heart, The Modern Heart, and The Future Heart--will focus on a major epoch in our understanding of the heart and the hidden history of cardiology. Erudite, witty, and enthralling, The Sublime Engine makes the heart come alive for readers.

When Einstein destroyed the old view of the universe, he destroyed the old notion of time with it. His new theory explained that time is a dimension of the physical cosmos like space, and like space it is relative. This collection of essays by theologians, physicists, and philosophers explores the theoretical aspects of the problem of time and its implications for faith and the understanding of God.

William Blake's The Four Zoas is one of the most challenging poems in the English language, and one of the most profound. It is also one of the least read of the major poetic narratives of the Romantic period. Spiritual History presents a much-needed introduction to the poem, but it will also be of great interest to those already familiar with it. The first full-length study to examine in detail Blake's numerous manuscript revisions of the poem, Spiritual History shows this much misunderstood poem to be the most extraordinary product of the eighteenth-century tradition of philosophical history.
