The immune system holds the key to human health. In The Beautiful Cure, leading immunologist Daniel M. Davis describes how the scientific quest to understand how the immune system works—and how it is affected by stress, sleep, age, and our state of mind—is now unlocking a revolutionary new approach to medicine and well-being.

The body’s ability to fight disease and heal itself is one of the great mysteries and marvels of nature. But in recent years, painstaking research has resulted in major advances in our grasp of this breathtakingly beautiful inner world: a vast and intricate network of specialist cells, regulatory proteins, and dedicated genes that are continually protecting our bodies. Far more powerful than any medicine ever invented, the immune system plays a crucial role in our daily lives. We have found ways to harness these natural defenses to create breakthrough drugs and so-called immunotherapies that help us fight cancer, diabetes, arthritis, and many age-related diseases, and we are starting to understand whether activities such as mindfulness might play a role in enhancing our physical resilience.

Written by a researcher at the forefront of this adventure, The Beautiful Cure tells a dramatic story of scientific detective work and discovery, of puzzles solved and mysteries that linger, of lives sacrificed and saved. With expertise and eloquence, Davis introduces us to this revelatory new understanding of the human body and what it takes to be healthy.

Biological immunity as we know it does not exist until the late nineteenth century. Nor does the premise that organisms defend themselves at the cellular or molecular levels. For nearly two thousand years “immunity,” a legal concept invented in ancient Rome, serves almost exclusively political and juridical ends. “Self-defense” also originates in a juridico-political context; it emerges in the mid-seventeenth century, during the English Civil War, when Thomas Hobbes defines it as the first “natural right.” In the 1880s and 1890s, biomedicine fuses these two political precepts into one, creating a new vital function, “immunity-as-defense.” In A Body Worth Defending, Ed Cohen reveals the unacknowledged political, economic, and philosophical assumptions about the human body that biomedicine incorporates when it recruits immunity to safeguard the vulnerable living organism.

Inspired by Michel Foucault’s writings about biopolitics and biopower, Cohen traces the migration of immunity from politics and law into the domains of medicine and science. Offering a genealogy of the concept, he illuminates a complex of thinking about modern bodies that percolates through European political, legal, philosophical, economic, governmental, scientific, and medical discourses from the mid-seventeenth century through the twentieth. He shows that by the late nineteenth century, “the body” literally incarnates modern notions of personhood. In this lively cultural rumination, Cohen argues that by embracing the idea of immunity-as-defense so exclusively, biomedicine naturalizes the individual as the privileged focus for identifying and treating illness, thereby devaluing or obscuring approaches to healing situated within communities or collectives.
