The conflict thesis is a historiographical approach in the history of science that originated in the 19th century with John William Draper and Andrew Dickson White. It maintains that there is an intrinsic intellectual conflict between religion and science, and that it inevitably leads to hostility. The consensus among historians of science is that the thesis has long been discredited, which explains the rejection of the thesis by contemporary scholars. Into the 21st century, historians of science widely accept a complexity thesis. The lack of engagement with the advancements in the history of science perpetuates belief in the thesis.
Global studies on scientists show that most scientists do not see religion and science in conflict  and studies on the views of the general public indicate that the conflict perspective is not prevalent either. 

== Historical conflict thesis ==

Before the 19th century, no one had pitted "science" against "religion" or vice versa in writing. The relationship between religion and science became an actual formal topic of discourse in the 19th century. More specifically, it was around the mid-19th century that discussion of "science and religion" first emerged because before this time, the term science still included moral and metaphysical dimensions, was not inherently linked to the scientific method, and the term scientist did not emerge until 1834. The scientist John William Draper (1811–1882) and the writer Andrew Dickson White (1832–1918) were the most influential exponents of the conflict thesis between religion and science. Draper had been the speaker in the British Association meeting of 1860 which led to the famous confrontation between Bishop Samuel Wilberforce and Thomas Henry Huxley over Darwinism, and in America "the religious controversy over biological evolution reached its most critical stages in the late 1870s". In the early 1870s, the American science-popularizer Edward Livingston Youmans invited Draper to write a History of the Conflict Between Religion and Science (1874), a book replying to contemporary issues in Roman Catholicism, such as the doctrine of papal infallibility, and mostly criticizing what he claimed to be anti-intellectualism in the Catholic tradition, but also making criticisms of Islam and of Protestantism. Draper's preface summarises the conflict thesis:

The history of Science is 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 one side, and the compression arising from traditionary faith and human interests on the other.

In 1874 White published his thesis in Popular Science Monthly and in book form as The Warfare of Science:

In all modern history, interference with science in the supposed interest of religion, no matter how conscientious such interference may have been, has resulted in the direst evils both to religion and to science—and invariably. And, on the other hand, all untrammeled scientific investigation, no matter how dangerous to religion some of its stages may have seemed, for the time, to be, has invariably resulted in the highest good of religion and of science.
Such thesis was not to be intended, as many successively did, as a statement of complete and necessary enmity between science and Christianity at all times. On the contrary White asserted that numerous examples of support from Christianity to science can be observed:

You will not understand me at all to say that religion has done nothing for science. It has done much for it. The work of Christianity has been mighty indeed. Through these two thousand years, despite the waste of its energies on all the things its Blessed Founder most earnestly condemned on fetich and subtlety and war and pomp it has undermined servitude, mitigated tyranny, given hope to the hopeless, comfort to the afflicted, light to the blind, bread to the starving, joy to the dying, and this work continues. And its work for science, too, has been great. It has fostered science often. Nay, it has nourished that feeling of self-sacrifice for human good, which has nerved some of the bravest men for these battles. Unfortunately, a devoted army of good men started centuries ago with the idea that independent scientific investigation is unsafe that theology must intervene to superintend its methods, and the Biblical record, as an historical compendium and scientific treatise, be taken as a standard to determine its results. So began this great modern war.
In 1896, White published A History of the Warfare of Science with Theology in Christendom, the culmination of over thirty years of research and publication on the subject, criticizing what he saw as restrictive, dogmatic forms of Christianity. In the introduction, White emphasized that he arrived at his position after the difficulties of assisting Ezra Cornell in establishing a university without any official religious affiliation.
The criticism of White is not entirely recent: historian of medicine James Joseph Walsh criticized White's perspective as anti-historical in The Popes and Science; the History of the Papal Relations to Science During the Middle Ages and Down to Our Own Time (1908), which he dedicated to Pope Pius X:
