Russian shot in quarrel over Kant's philosophy.
A police spokeswoman in Rostov-on Don, Viktoria Safarova, said two men in their 20s were discussing Kant as they stood in line to buy beer at a small store on Sunday.
The discussion deteriorated into a fistfight and one participant pulled out a small nonlethal pistol and fired repeatedly.
The victim was hospitalized with injuries that were not life-threatening.
Neither person was identified.
It was not clear which of Kant's ideas may have triggered the violence.
