the same idea in 1817. In 1847 he published the observation that all solids glow red at about the same temperature, about 977 °F (798 K), which has come to be known as the Draper point. On Saturday 30 May the 1860 Oxford evolution debate featured Draper's lecture on his paper "On the Intellectual Development of Europe, considered with reference to the views of Mr. Darwin and others, that the progression of organisms is determined by law." Draper's presentation was an early example of applying a Darwinian metaphor of adaptation and environment to social and political studies, but was thought to be long and boring. The hall was crowded to hear Bishop Samuel Wilberforce's views on Charles Darwin's recent publication of On the Origin of Species, and the occasion was a historically significant part of the reaction to Darwin's theory due to reports of Thomas Henry Huxley's response to Wilberforce. Contributions to the discipline of history: Draper is well known also as the author of The History of the Intellectual Development of Europe (1862), applying the methods of physical science to history, a History of the American Civil War (3 vols., 1867–1870), and a History of the Conflict between Religion and Science (1874). The last book listed is among the most influential works on the conflict thesis, which takes its name from Draper's title. His book examined the relationship between religion and science, dismissing ideas of harmony and presenting the history of science as "not a mere record of isolated discoveries; it is a narrative of the conflict of two contending powers, the expansive force of the human intellect on the one side, and the compression arising from traditional faith and human interests on the other." After outlining the origins of science in ancient Greek philosophy, Draper presented the development of Christianity as leading to repression of science. His argument, aimed at his fellow Protestants, employed anti-Catholic rhetoric, but also said that these "two rival divisions of the Christian church" were "in accord on one point: to tolerate no science except such as they considered agreeable to the Scriptures", and both were liable to "theological odium". The book went through fifty printings in the United States alone, and was translated into ten languages. Professor Ronald Numbers has pointed to Draper's book as a source of popular misconceptions about historical conflict between science and religion, saying that it was "less of
