Anyone who studies the history of science will know the frustration that is the "Conflict Thesis". This is the false but culturally-pervasive idea that religion and science have been at war down the ages, with religion constantly trying to hold back scientific advancement. In its more extreme form it also declares that religion and science are totally incompatible and only unbelievers can be "true" scientists. This mythic idea was most fully developed by John William Draper's History of the Conflict between Religion and Science (1874) and Andrew Dickson White's History of the Warfare of Science with Theology in Christendom (1896), which is why the "Conflict Thesis" is also referred to as the "Draper-White Thesis". These two books became immensely popular, widely read and heavily influential. And the thesis they present remains widely accepted in the popular sphere, despite being long since rejected by actual historians of science.
The persistence of this false set of ideas has stubbornly resisted attempts by historians to debunk the Conflict Thesis and to get the wider public understand the far more accurate and nuanced modern view on the relationship between religion and science. Unfortunately learned (but fairly dry) volumes such as The Warfare Between Science and Religion: The Idea that Wouldn't Die (J. Hardin, R.L. Numbers, R.A. Binzley eds, Johns Hopkins University Press, 2018) don't do much to penetrate the popular consciousness. A more accessible collection of short essays, Galileo Goes to Jail and Other Myths About Science and Religion (R.L. Numbers, Harvard University Press, 2010) debunks a number of key myths that make up the Conflict Thesis, but doesn't tackle it head on. This is why Hutchings and Ungureanu's Of Popes and Unicorns is a welcome and useful popular account of how the Conflict Thesis arose, why it persists and how it is wrong.
The real strength of this book is in its accessibility. It's a fun read and written in a fairly light-hearted and even conversational style, punctuated by quirky historical episodes and interesting analogies. I had never heard of the fictional (and then, oddly, non-fictional) hamlet of Agloe, New York, but the authors tell the strange story of an invented town that then came-to-be, before putting it to use to illustrate a point. There are also enough topical references and jokes to make what could be a dull exposition on historiography a lively tour of science through history.
Even better, the authors bring together a wide range of information in a fairly short and highly readable package. I have been studying this subject for many years, but I learned quite a few new things from this book, particularly about the backgrounds of White and Draper and their cultural and historiographical predecessors. The core of the book, where the central myths of the Thesis and its key figures (Hypatia, Bruno, Galileo etc.) are carefully debunked, will be familiar ground for those who have studied the history of science. But this material is presented in a way that allows the popular reader to understand why these commonly (even dogmatically) accepted myths are wrong and why the real stories of these episodes are far more interesting.
The final section of the book on why the Conflict Thesis persists despite being rejected by historians for over a century is also useful, if a little rueful in places. It is particularly so for me, given that the authors very kindly note my website History for Atheists (p. 222) in their section on efforts to change the common acceptance of the Thesis in the popular sphere. Here the authors note how this is something of an uphill battle, given the high profile of modern proponents of the Conflict Thesis:
"Sagan's Cosmos had 500 million viewers in the 1980s: Tim O'Neill gets a few thousand on YouTube today." (p. 223)
Quite. Still, despite the efforts of some of my more historically illiterate fellow atheists, doubt about the Conflict Thesis' claims is perhaps slowly starting to creep beyond academia. If this is to continue, we'll need more well-researched, judicious, persuasive and entertaining popular works like Of Popes and Unicorns. This is an excellent example of public education on a subject that sorely needs more efforts of this kind. Highly recommended.
