"Our hearts have evolved to be extremely efficient, long-lasting pumps that exquisitely match the needs of our bodies. This book is about how the heart does this; how can a heart pump the blood for up to one hundred years while the best formula one racing engine has a working life measured in hours? Why is the heart so efficient, and how are worn out parts replaced while working? How does it generate the force to act as a pump, how is it controlled electrically, and how can it repair itself? This book addresses these questions from physiological and molecular perspectives in language that aims to be accessible to all interested in biology and with liberal illustrations. The story of how the heart works is presented in the context of its origins; How is the heart formed in the womb? How it evolved as an oxygen pump through many configurations following the onset of oxygenic photosynthesis 2.5 billion years ago? Why its intimate co-evolution with the circulation and blood was essential to enable its efficiency and longevity? The book begins with a discussion of why the word heart is universally used as a metaphor for reason and emotion and traces its origins in modern and ancient languages. The last chapter explains why most diseases of the heart can be attributed to a divergence between the lifestyle for which the heart is optimally evolved, and those lived today in high-income nations and increasingly in middle and lower-income nations. Advice on how to preserve the heart is presented in light of this"--

"Fascinating . . . Surprising entertainment, combining deep learning with dad jokes . . . [Schutt] is a natural teacher with an easy way with metaphor.”—The Wall Street Journal In this lively, unexpected look at the hearts of animals—from fish to bats to humans—American Museum of Natural History zoologist Bill Schutt tells an incredible story of evolution and scientific progress. We join Schutt on a tour from the origins of circulation, still evident in microorganisms today, to the tiny hardworking pumps of worms, to the golf-cart-size hearts of blue whales. We visit beaches where horseshoe crabs are being harvested for their blood, which has properties that can protect humans from deadly illnesses. We learn that when temperatures plummet, some frog hearts can freeze solid for weeks, resuming their beat only after a spring thaw. And we journey with Schutt through human history, too, as philosophers and scientists hypothesize, often wrongly, about what makes our ticker tick. Schutt traces humanity’s cardiac fascination from the ancient Greeks and Egyptians, who believed that the heart contains the soul, all the way up to modern-day laboratories, where scientists use animal hearts and even plants as the basis for many of today’s cutting-edge therapies. Written with verve and authority, weaving evolutionary perspectives with cultural history, Pump shows us this mysterious organ in a completely new light.

Reveals the use of direct perception in understanding Nature, medicinal plants, and the healing of human disease • Explores the techniques used by indigenous and Western peoples to learn directly from the plants themselves, including those of Henry David Thoreau, Goethe, and Masanobu Fukuoka, author of The One Straw Revolution • Contains leading-edge information on the heart as an organ of perception All ancient and indigenous peoples insisted their knowledge of plant medicines came from the plants themselves and not through trial-and-error experimentation. Less well known is that many Western peoples made this same assertion. There are, in fact, two modes of cognition available to all human beings--the brain-based linear and the heart-based holistic. The heart-centered mode of perception can be exceptionally accurate and detailed in its information gathering capacities if, as indigenous and ancient peoples asserted, the heart’s ability as an organ of perception is developed. Author Stephen Harrod Buhner explores this second mode of perception in great detail through the work of numerous remarkable people, from Luther Burbank, who cultivated the majority of food plants we now take for granted, to the great German poet and scientist Goethe and his studies of the metamorphosis of plants. Buhner explores the commonalities among these individuals in their approach to learning from the plant world and outlines the specific steps involved. Readers will gain the tools necessary to gather information directly from the heart of Nature, to directly learn the medicinal uses of plants, to engage in diagnosis of disease, and to understand the soul-making process that such deep connection with the world engenders.

From one of America's great professors, a collection of works exploring the importance of reading, writing, and teaching well, for anyone invested in the future of the humanities. In his series of books Why Read?, Why Teach?, and Why Write? Edmundson, a renowned professor of English at the University of Virginia, explored the vital worldly roles of reading, teaching, and writing, earning a vocal following of writers, teachers, and scholars at the top of their fields, from novelist Tom Perrotta to critics Laura Kipnis and J. Hillis Miller. He has devoted his career to tough-minded yet optimistic advocacy for the humanities, arguing for the importance of reading and writing to an examined and fruitful life and affirming the invaluable role of teachers in opening up fresh paths for their students. Now for the first time The Heart of the Humanities collects into one volume this triad of impassioned arguments, including an introduction from the author on the value of education in the present and for the future. The perfect gift for students, recent graduates, writers, teachers, and anyone interested in education and the life of the mind, this omnibus edition will make a powerful and timely case for strengthening the humanities both in schools and in our society.
