"This is an extraordinary book. Louis Liebenberg, our intrepid and erudite guide, gives us a fascinating view of a people and a way of life that have much to say about who we are, but which soon will vanish forever. His data are precious, his stories are gripping, and his theory is a major insight into the nature and origins of scientific thinking, and thus of what makes us unique as a species." Steven Pinker, Harvard College Professor of Psychology, Harvard University, and author of How the Mind Works.
"Louis Liebenberg's argument about the evolution of scientific thinking is highly original and deeply important." Daniel E. Lieberman, Professor of Human Evolutionary Biology at Harvard University.
"The Origin of Science is a stunningly wide-ranging, original, and important book." Peter Carruthers, Professor of Philosophy, University of Maryland, and author of The Architecture of the Mind.
"Louis Liebenberg is a scholar and adventurer whose work combines academic rigor, inspired leaps of insight, and a remarkable willingness to risk himself in pursuit of an idea." Christopher McDougall, author of Born to Run.
