With a pathologist's trained eye for observation of detail and a style unrivalled in elegance and wit, Gonzalez-Crussi discusses science, religion, and philosophy, on topics, such as the origin of life in the universe, the complex evolution of human sexuality, and the debate over when the soul is acquired. Drawing on a variety of sources spanning the fields of biology, literature, history, myth, medicine, and philosophy, "On Being Born" surveys a vast field of opinions and theories, contrasting the supremely rational processes by which we evolved on this planet with our irrational and often bizarre attempts to understand them. Gonzalez-Crussi traces millennia of misunderstandings to their sources - Aristotle, Hippocrates, Descartes, Sir Thomas Browne, Cervantes, Rabelais, Maupassant, and Nietzsche, among others.
