Clarence Thomas graduated cum laude from the College of Holy Cross in Massachusetts in 1971 and received a J.D. from Yale University in 1974. His memoir, My Grandfather’s Son (2007), testifies to a much deeper educational journey—one that began under the determined watch of his maternal grandfather in Jim Crow Savannah and that culminated in his ordeal during the 1991 Senate confirmation hearings. In between came his appointments as head of the Office for Civil Rights in the Department of Education, chairman of the Equal Employment Opportunity Commission, and member of the U.S. Court of Appeals for the District of Columbia Circuit.
What he learned in those positions was significant, but not transformational. The transformational moment, we learn in Myron Magnet’s new book, Clarence Thomas and the Lost Constitution, came in 1980, “after he read through [Thomas] Sowell’s works, registered as a Republican, and voted for Ronald Reagan.” He was drawn by Reagan’s “promise to end racial social engineering.” Thomas had had a bellyful of that at Yale and had concluded that “blacks would be better off if they were left alone” instead of being conscripted into the utopian schemes of liberal politicians.
Needless to say, this wasn’t an idea he picked up from his teachers at Holy Cross or Yale, though it did owe something to his grandfather. Moreover, it prepared him for the opportunity he had at the EEOC when “he hired as special assistants Ken Masugi and John Marini, students of political philosopher Harry Jaffa.” Masugi and Marini introduced Thomas to texts that deepened his knowledge of the American founding.
