Idéographie is a “choreography of ideas” composed and interpreted by Noé Soulier. He has used books about philosophy, music, linguistics or cognitive science, extracting passages from them and composing analyses of them. These writings constitute the raw material of the dance presented. Far from translating the texts through movements of his body, Noé Soulier here sets out to “put together concepts and arguments in such a way that they work as a dance”. At first sight Int-ext is no more than an Éditions de la Pléiade book exhibited open at the first page of Pot-bouille by Emile Zola. However, the text is interspersed with extracts from How the Body Shapes the Mind by Shaun Gallagher. The gradual merger of the novel and the philosophical writing gives rise to a landscape of ideas in which the observer’s perception evolves. Noé Soulier, born in 1987 in Paris, lives and works in Paris and Brussels.
