“Open School of Philosophy” was a project of my doctoral research. It took place over the summers of 2007 and 08 at Gloucester Green market in Oxford. An anthropologist, horticulturist, archaeologist, occupational therapist, composer and political analyst were invited to exchange their knowledge with participants. There was a pamphlet for each specialist. A banner depicting the Rosicrucian fortress of knowledge with an open door accompanied the events.
