Headhunters: The Search for a Science of the Mind traces a slice of history that in turn introduces us to some of those drawn to study human psychology and mental health a few decades after Darwin’s theory of evolution took root. Four of these pioneers are the focus of this book: William Rivers, Grafton Elliot Smith, Charles Myers, and William McDougall. They met at Cambridge in the 1890s and Shephard links their lives more broadly through their efforts to study the brain as biological approaches were gaining increased leverage due to Darwin’s work. The author begins the book by placing us in that context:
“How, then, did the human brain evolve? Why did it evolve as it did? In the 1870s, modern experimental neuroscience began, using electricity to stimulate the nervous system of animals and microscopes to observe the nerve cells of humans. Within two decades, researchers had established the location of functions within the brain, unraveled the way that the nervous system automatically governs the body’s functions, and begun to discover how messages are sent between neurons and synapses. But these extraordinary advances only posed further questions — about human behavior; man’s relations to his fellow primates, and the human occupation of the earth. A generation of scientists went looking for answers” (p. 1).
