In this lecture, we examine one formulation of the historical relationship between science and religion - the warfare or conflict thesis. Loudly advanced in the late 19th century by two men - John William Draper and Andrew Dickson White - it has continued strong in popular thought down to the present day. We will examine how this formulation rests on very shaky (and sometimes fabricated) foundations and was contrived largely for quite specific political, professional, and racist purposes. One value of this examination is to create a catalogue of methodological errors and fallacies for all readers of history to be on guard against. Serious modern historians of science have unanimously dismissed the warfare model as an adequate historical description
