Are humans really unable to stop putting each other into categories of dominant and submissive, lower and higher, those richly layered constructions, that instruct our position in every encounter? Wilkerson reveals this country's stark duplicity, the divide between our ideals and reality, against the grand history of human divisiveness with thorough, unflinching research. She also dives into intimate personal stories with compassion. She ends with positive examples and hope that we can move forward together to the betterment of all of us. Random House.
