CAMBRIDGE, MA - During an introductory lecture, intellectual history professor Irma Hackenheim insisted that students don't even need to exist in the physical universe for them to come to office hours.

 

"My door is always open. You don't need to have specific questions prepared in advance. You don't need to have a general idea of what you want to discuss," said Hackenheim. "In fact, you don't need to be a living, breathing human being. There are absolutely no requirements."
