In June 1985, a fortnight's discussions on ‘The Theatre in the Future’ were held as part of the Fools' Festival in Copenhagen. The seminars discussed the position of theatre and its possibilities in a rapidly changing society, often from deeply opposed positions – socially engaged versus wildly avant-garde, verbal versus imagistic, anthropological versus robotic, and so on. Participants were an exciting mix of professional performers of many kinds, plus theatre critics and ‘ordinary’ engaged people, who for two weeks exchanged experiences and visions of theatre in conjunction with other art forms, and with science and politics. The manifesto below was the contribution to these seminars of John Andreasen, a veteran of ‘sixties happenings, who has subsequently concentrated on street and environmental theatre, and for the past twelve years has taught and directed in the Drama Department of the University of Aarhus.
