Bill Mollison's prospectus for a permaculture Academy may be found in his "Permaculture Academy Yearbook" (pdf)
“{guides and mentors} have deeply embedded in my mind the ideas of freedom of enquiry, of fair judgement, of persistence, of universalism, and of excellence. I would like, in this Academy, to return to basic values, to the ideal of teachers and students as the body of a university that values those ideals for which our intellectual ancestors lived, and often for which they died, were outcast, or disenfranchised. It is always necessary to return to the roots of knowledge and the origins of institutions, for the latter drift from their purposes even if many individuals hold true to origins and ideals.”
There are echoes here of Ivan Illich's observations on a good education system.
