"... the most serious of the prohibited acts, like murder and torture, are not just supposed to require unusually strong justification. They are supposed
never to be done, because no quantity of resulting benefit is thought capable of
justifying such treatment of a person." (142-143)
Nagel and Kantianism hold that it's never right to use such strong tactics as murder or torture, because they fundamentally violate the rational, autonomous will that Kantianism values so highly. Just as fundamentally, however, war entails conflict and is essentially a clash in perceptions of power. Is it war that Kantianism has a problem with, or is it the exertion of power? Is there any for Kantianism to coexist peacefully with power clashes?
