No state more extensive than the minimal state can be justified. - Robert Nozick

as a young man I thought the ideal philosophical argument was one with the following property: someone who understood its premises and did not accept its conclusion would die.

Our principles fix what our life stands for, our aims create the light our life is bathed in, and our rationality, both individual and coordinate, defines and symbolizes the distance we have come from mere animality. It is by these means that our lives come to more than what they instrumentally yield. And by meaning more, our lives yield more.

Maximising the average utility allows a person to kill everyone else if that would make him ecstatic, and so happier than average.
