well as Western primacy in technology to Western theology's "activist" tradition and "implicit assumption of the infinite worth of even the most degraded human personality" and its "repugnance towards subjecting any man to monotonous drudgery." In 1942, White published a paper titled "Christian Myth and Christian History" in which he wrote about the relationship between historians and Christianity. He wrote: "Having lost faith that God revealed himself uniquely at one single point in history, we are relapsing into the essentially static or repetitive view of the time-process typical of antiquity and of the East" and "the Virgin Mother, undefiled yet productive, bearing Christ into the world by the action of the Spirit of God, is so perfect an analogue of the most intimate experience of the soul, that powerful myth has sustained dubious history; for, to the believer, myth and history have been one" and "Christianity above all other religions has rashly insisted that its myth really happened in time" and "we stand amid the debris of our inherited religious system."

At Mills College, White published on education and women, including "Women's Colleges and the Male Dominance" (1947), "Unfitting Women for Life" (1949), "Educating Women in a Man's World" (1950), and "The Future of Women's Education" (1953). He was an elected member of both the American Academy of Arts and Sciences (1956) and the American Philosophical Society (1968). Medieval technology and social change At UCLA, he used a set of lectures from 1957 to form his best-known work, Medieval Technology and Social Change in 1962. This book revisited almost all the themes from "Technology and Invention in the Middle Ages" 22 years earlier, but included a controversial theory about the stirrup. White contended in the first section of the book that the stirrup made shock combat possible, and therefore had a crucial role in shaping the feudal system. He believed this motivated Charles Martel to accelerate confiscation of church-held lands to distribute to his knights, who could then bear the cost of expensive horses themselves to support him in battle. In the second section of the book, White explained the shift in power from the Mediterranean to Northern Europe as a result of increased productivity due to technological changes that produced a "heavy
