"What can everyone do? Praise and blame. This is human virtue, this is human madness"

This quote recommends that the human ability to praise and blame others is both a virtue and a madness. On one hand, it allows people to examine the actions of others and hold them responsible. On the other hand, it can lead to excessive criticism and unjustified praise, which might be harmful to the individual being assessed. Basically, Nietzsche is highlighting the duality of human behavior and the potential for it to be both helpful and destructive.
