There are many impressive philosophical points that can be made against racism and all kinds of tribal superiority but this book takes a purposely scientific approach in confronting the issue. The arsenal of examples is impressive and unites archeology, epidemiology, climatology, linguistics... The author starts with a note about human intelligence and our inherently subjective methods of measuring it. Then, chapter by chapter, the most widespread assumptions of racial supremacy are put under the microscope, dissected with facts, and ultimately refuted as misguided prejudice, or (at best) a misunderstanding of causes and effects. Here and there the author sprinkles some humor, which makes this book easy to read, and this is achieved without sacrificing quality or diminishing the seriousness of its message.
