The quote in the title of this paper is taken from the first line of Marc Depaepe's article "An Agenda for the History of Colonial Education", published in "The Colonial Experience in Education" (Ghent, 1995). This presentation takes as its focus the informal learning space of the museum and the art gallery, and the emergence in recent years of curatorial activism. It seeks to explore the changing discourse and politics around addressing through display the history of colonialism and its meaning in today's globalised world.
