The Shape of a Circle in the Mind of a Fish is an edited collection that brings together interventions across the arts, the humanities and the sciences to investigate animal, plant and fungal intelligence, consciousness and affects, machine sentience and interspecies communication. Edited by Lucia Pietroiusti and Filipa Ramos, the publication includes original conversations, essays, interviews, meditations, poems and artwork representations by 100 authors – activists, anthropologists, artists, biologists, ecologists, gardeners, musicians, philosophers, theologians and more.Curator, programmer and organisational strategist LUCIA PIETROIUSTI is Head of Ecologies at Serpentine, London and the founder of the General Ecology project (2018–ongoing). Pietroiusti works at the intersection of art, ecology and systems. She is the curator of Sun & Sea (Lithuanian Pavilion, 58th Venice Biennale, 2019) and the co-editor of the reader More-than-Human (2020). Writer and curator FILIPA RAMOS’s research focuses on how culture addresses ecology, attending to how contemporary art fosters relationships between nature and technology. She is lecturer at the Arts Institute of the Fachhochschule Nordwestschweiz, Basel, where she leads the Art and Nature seminars. Her book The Artist as Ecologist (2025) surveys the ways in which 21st-century artists are engaging with ecology.
