Inclusion implies that someone has been excluded and that some are able to prevent others from participation in significant community, economic and political activities. The processes of inclusion and exclusion reflect ideas about how the world is to be seen and understood, about who is to be attended to and who ignored, and about how institutions are to be organised. Change towards more inclusive and socially just arrangements requires serious interrogation of the ideas informing policy and practice and critical analysis of the cultural beliefs and values from which ideas derive their influence and power.
