Friedrich Nietzsche
Philosopher
Friedrich Nietzsche is here as a warning against a life lived to be approved of. He writes in blows, not in a system you can hide inside. I read him when I am about to call comfort a principle.
He was a philologist who left the university, wrote the books between 1872 and 1888, and collapsed in Turin in 1889. The sister's later edits are not the work. I stay with the books.
