Quote by Bertrand Russell
The most savage controversies are those about matters as to which there is no good evidence either way. Persecution is used in theology, not in arithmetic.
Summary
This quote highlights the intensity of disagreements when there is a lack of substantial evidence supporting either side of an argument. It suggests that the most bitter and aggressive disputes occur in areas where opinions dominate, such as religion, rather than in factual fields like mathematics. Unlike arithmetic, which relies on concrete evidence, theology often encourages persecution as people defend their beliefs fervently despite the absence of compelling proof. The quote implies that disagreements rooted in uncertainty and a dearth of evidence tend to ignite hostility and conflict.
