Something I've just remembered.
A professor told me last semester that scholarship isn't personal and criticism isn't personal either. He was referring to the fact that other students and I had protested against the way he was talking to us which felt very condescending. His point of view was that it was an impartial critique.
I told my brother about this who is a student of medicine. He just laughed and said, "But you're in humanities! Everything is personal because it all happens in your minds! How can criticising someone's thoughts not be personal?"
He's got a point.
I'm glad I'm not a scientific robot, or a history wonk who pretends that history is a science.
