MOSCOW (Reuters) - An argument over the theories of 18th century philosopher Immanuel Kant ended in a man being shot in a grocery store in southern Russia.

RIA news agency quoted police in the city of Rostov-on-Don as saying a fight broke out between two men as they argued over Kant, the German author of “Critique of Pure Reason”, without giving details of their debate.

“In the course of the fight, the suspect took out a pistol firing rubber bullets and fired several shots at his opponent,” it said, adding that one man was detained and the victim was taken to hospital. His life was not in danger.

Kant lived in Koenigsberg, which is now the Russian city of Kaliningrad, and is a central figure of modern philosophy. Many Russians love to discuss philosophy and history, often over a drink, but such discussions rarely end in shootings.
