Oh I sympathize with Nietzsche as a human. I only criticize
  because of his influence. He has the "I've got the answers"
  ethos about him which brings lots of people to believe him, much
  like Ayn Rand or any other systemic philosopher. What's nice
  about book-wisdom is it's personal. Cultural wisdom brings your
  aunt and uncle, grandparents and neighborhood into it. Messier
  stuff. Easier when there's a book or two.
