Professor Guilherme Moura Fagundes (Department of Anthropology – FFLCH/USP) is the guest on the Café da Manhã podcast (Folha de S.Paulo), in an episode about the Sanctuary on the Moon project. This initiative brings together researchers and artists to decide which knowledge and records of life on Earth should comprise an analog library, recorded on 24 microscopic sapphire discs and destined to remain deposited on the Moon. In the conversation, Fagundes presents the workings of the project's interdisciplinary workshops and reflects on the meaning of choosing what "deserves to be saved," the limits of any universal archive, and the consequences of building a sanctuary of knowledge in times of crisis.
