There is no question more fundamental to human existence than that posed by the nature-versus-nurture debate. For much of the past century, it was widely believed that there was no essential human nature and that people could be educated or socialized to thrive in almost any imaginable culture. Today, that orthodoxy is being directly and forcefully challenged by a new science of the mind: evolutionary psychology. Like the theory of evolution itself, the implications of evolutionary psychology are provocative and unsettling. Rather than viewing the human mind as a mysterious black box or a blank slate, evolutionary psychologists see it as a physical organ that has evolved to process certain types of information in certain ways that enables us to thrive only in certain types of cultures.In On Our Minds, Eric M. Gander examines all sides of the public debate between evolutionary psychologists and their critics. Paying particularly close attention to the popular science writings of Steven Pinker, Edward O. Wilson, Richard Dawkins, and Stephen Jay Gould, Gander traces the history of the controversy, succinctly summarizes the claims and theories of the evolutionary psychologists, dissects the various arguments deployed by each side, and considers in detail the far-reaching ramifications—social, cultural, and political—of this debate. Gander's lucid and highly readable account concludes that evolutionary psychology now holds the potential to answer our oldest and most profound moral and philosophical questions, fundamentally changing our self–perception as a species.
