A philosophical debate led to a near-fatal shooting at a bottle shop in Russia this week.
Though it sounds like the beginning of a bad joke, two men were waiting to buy beer at a store when they began discussing Immanuel Kant's "Critique of Pure Reason."
The discussion became heated and one of the men brandished an air gun.
The shooter fired several rubber bullets at his interlocutor, injuring him.
The victim was sent to hospital with non-life-threatening injuries. The assailant was arrested while trying to flee.
He faces 10 years in prison over the incident.
Kant was one of the most prominent philosophers of the 18th century. He wrote in the Prussian city of Konigsberg, which is now the Russian city of Kaliningrad.
It is unclear if it was Kant's "categorical imperative" that drove the man over the edge.
