And, while Felman’s argument targets ignorance not as a lack of knowledge (I would agree with her on this point) she does characterize unknowing in a negative light as "an active refusal of information." This refusal she attributes to the student as an internalized resistance to knowledge, to say, literature, for example.
Another hazard of Felman’s theory based largely on Lacan’s seminars and his success with stellar students in their undoubtedly amazing instances of collaborative discovery learning, is the disrespect students (already infected by half-knowledge) may show a teacher who relinquishes her authority in the classroom, even if deliberately, as a pedagogical ruse.
