To say that "government is a necessary evil", is it to say that "It is necessary that government be evil"? If that's the case, then that's a pretty despotic way of looking at the role of government. Why can't government be a necessary 'Good'? Why can't positive psychology see through the darkness that is pessimism and Luciferianism and exile those notions to the depths of human nature, instead of raising it to the pinnacle of human being's ego?
