Full Idea
Nothing would be more expensive than virtue: for in the end it would give us the earth as an infirmary, and 'Everyone to be everyone else's nurse' would be the pinnacle of wisdom.
Gist of Idea
Virtue is wasteful, as it reduces us all to being one another's nurse

A Reaction
Once again, I think that Nietzsche does not understand Aristotelian virtue theory. This attacks Christian virtue (his bête noir), with its emphasis on compassion and humility. A truly virtuous person is more likely to be an artist/politician/philosopher.
