How Not to Conduct a Philosophical Debate

This may be a first. Two guys standing in line for beer get into an argument over Immanuel Kant's philosophy and one shoots the other. Don't tell me nobody takes philosophy seriously anymore:

MOSCOW (AP) -- An argument in southern Russia over philosopher Immanuel Kant, the author of "Critique of Pure Reason," devolved into pure mayhem when one debater shot the other.

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.

My guess is they were quarreling over Kant's theory of transcendental apperception. Or perhaps it was his categorical imperative which brought the men to blows. The categorical imperative is a rule that enjoins us to always act in ways we would want everyone to act. If this was indeed the point of contention we may presume that the shooter was arguing against adoption of the rule.
