“In the ensuing centuries, texts that contained such dangerous ideas paid a heavy price for their ‘heresy’. As has been lucidly argued by Dirk Rohmann, an academic who has produced a comprehensive and powerful account of the effect of Christianity on books, some of the greatest figures in the early Church rounded on the atomists. Augustine disliked atomism for precisely the same reason that atomists liked it: it weakened mankind’s terror of divine punishment and Hell. Texts by philosophical schools that championed atomic theory suffered. The Greek philosopher Democritus had perhaps done more than anyone to popularize this theory – though not only this one. Democritus was an astonishing polymath who had written works on a breathless array of other topics. A far from complete list of his titles includes: On History; On Nature; the Science of Medicine; On the Tangents of the Circle and the Sphere; On Irrational Lines and Solids; On the Causes of Celestial Phenomena; On the Causes of Atmospheric Phenomena; On Reflected Images . . . The list goes on. Today Democritus’s most famous theory is his atomism. What did the other theories state? We have no idea: every single one of his works was lost in the ensuing centuries. As the eminent physicist Carlo Rovelli recently wrote, after citing an even longer list of the philosopher’s titles: ‘the loss of the works of Democritus in their entirety is the greatest intellectual tragedy to ensue from the collapse of the old classical civilisation’.”
