e: For a funny example, 'Marxist philosopher' Althusser admitted once that he essentially had no real knowledge of Marx or Hegel when he became a professor, and that he would often assign essays on philosophers purely so he could learn while he was grading them. He even proudly proclaimed that he "learned by hearsay" and would tell colleagues this. Don't Do That!
