“All right! We can lie without simply following the rule “It is permissible to lie“ and instead, follow a rule that pertains only to specific circumstances, like “It is permissible to lie when doing so will save a life, and thus such a rule can be made a universal law without contradiction, don’t you see? No?”

From Russia comes this story:

“A “passionate argument” about 18th-century Enlightenment philosopher Immanuel Kant, renowned for his treatises on ethics, “deteriorated into a fistfight” between two men waiting in line for beer during an outdoor City Day event in the southern Russian metropolis of Rostov-on-Don, police said Monday. The argument ended when one of the debaters pulled out an air gun and shot the other in the head, local police said in a statement. The shooter then fled the scene but was later detained, police said. The other man’s wound was not critical, but he was hospitalized, the statement said…”

I am fairly certain that Kant would have said that shooting someone in the head with an air gun to settle a debate over ethics violates his Rule of Universality, which has the seldom-cited codicil, “Don’t shoot people in the head, unless you want to live in a world where everyone gets shot in the head.” It is a perfect example of losing an argument by winning an argument.

And you thought the ethics debates got heated on Ethics Alarms!
