Draper, John William

John William Draper (1811-1882) was an English-American scientist, physician, and historian who significantly influenced 19th-century discourse on the relationship between science and religion. His most controversial work, History of the Conflict between Religion and Science (1874), popularized the "conflict thesis" - the view that science and religion are fundamentally incompatible and locked in perpetual warfare. Draper argued that scientific progress inevitably leads to the decline of religious authority, particularly criticizing the Catholic Church for suppressing scientific advancement. While his thesis dominated popular understanding for decades, modern historians of science have largely rejected this oversimplified narrative, recognizing instead complex interactions between religious and scientific communities. Despite its scholarly limitations, Draper's work profoundly shaped public perception of science-religion relations and remains a pivotal text in understanding how the perceived conflict between faith and reason became embedded in Western culture.
