This is interesting for me as it enacts the two important perspectives on knowledge that determined the conflict over who should own it. One is that a core of knowledge is foundational to all new knowledge and discovery is bent on enriching it - requiring academic Masters to protect and impart it. The other that all knowledge is contingent, ideological and political and new knowledge will be produced by those who can depart from it on the basis of individual inquiry and personal discovery.
