The Vitals of History is before Chapter Two: An Old House and an Infrared Light.

"When we go to the doctor, he or she will not begin to treat us without taking out history—and not just our history but that of out parents and grandparents before us. The doctor will not see us until we have filled out many pages on a clipboard that is handed to us upon arrival. The doctor will not hazard a diagnosis until he or she knows the history going back generations." —Isabel Wilkerson, Caste: The Origins of Our Discontent, Page #13(Hardcover)

"The Afterlife of Pathogens" is the first chapter of Caste: The Origins of Our Discontents
"What humanity learned, one would hope, was that an ancient and hardy virus required perhaps more than anything, knowledge of its ever-present danger, caution to protect against exposure, and alertness to the power of its longevity, its ability to mutate, survive and hibernate until reawakened." — Isabel Wilkerson, Caste: The Origins of Our Discontents, Page 12

The first episode of Reading Caste With Jack. I read the very first chapter/prologue of Caste: The Origins of Our Discontents. 
"We would like to believe that we would have taken the more difficult path of standing against injustice in defense of the outcaste." — Isabel Wilkerson, Caste: The Origins of Our Discontents, Page xvii
