"William James, MD: Philosopher, Psychologist, Physician"

"James was awarded his MD from Harvard Medical School in March 1869, after more than five years of interrupted study. This certificate lists his examiners, who included Oliver Wendel Holmes Sr., and the subject of his thesis, namely, the effects of cold on the body. (Diplomas, degrees, notifications of appointments, etc., William James papers [MS Am 1092.9–1092.12, MS Am 1092.9 (4571), Box: 40], Houghton Library, Harvard University.)

There is one element of James’s life and work that unites these disparate identities, however. In 1869, several years before he secured his first lectureship, he graduated from Harvard Medical School and earned his MD. Hampered by his own ill health, James abandoned his plans to practice as a doctor, but these studies were only the beginning of a profound and lifelong occupation with questions about the essential nature of health, healing, and invalidism and their implications for society. His writings, across their disciplinary breadth, return time after time to issues of a medical provenance. In this book I make the case that James’s medical interests, concerns, and values are the threads that bind many of his seemingly unconnected pursuits together. They are the warp and weft of many of his best-known publications and major lines of thought."
