'Mortal Coil' explores the medical, scientific and philosophical theories behind the quest for the prolongation of human life. It was a conundrum that intrigued Sir Francis Bacon and underpinned the scientific revolution; ideas of ultimate perfectibility, indefinite progress, and worldly rather than heavenly immortality, fed directly into the spirit of the Enlightenment and further into the nineteenth and twentieth centuries. In today's world of genetic research, cryonics and nanotechnology, we still seek the same elusive philosopher's stone. From Adam and Eve to human cloning and designer babies, seventeenth-century lifestyle guides to science fiction, Haycock's gripping story introduces an array of fascinating individuals - Rene Descartes, Benjamin Franklin, Jonathan Swift, Charles Darwin and Sigmund Freud as well as a score of unknown figures. Full of extraordinary stories and valuable insights, this is a curious, witty and captivating exploration into our unceasing desire to live forever.
