This book is an extension of the 2019 exhibition The Probable Causes of Future Experience which explores what it is to experience the world from a child's perspective. Irish Artist Yvonne Higgins has used materials drawn from instructional manuals, illustrated encyclopaedias, family health guides, books about wildlife and the natural world, to investigate the power dynamic between adult and child and the shifting boundaries between adulthood and childhood. Between Four Walls extends the artist's work through collaboration with an invited panel of international poets who have responded to her collages and photographs. It is prefaced by an essay on representing childhood by historian Mathew Staunton and artist Ian Joyce.
