Starting with the characterization of Baruch Spinoza’s work as a “theory of expression” and with the influence that Gilles Deleuze’s philosophy has on multinaturalist perspectivism, this article speculates on the possibility of a theory of expression for multinaturalism. First, one proceeds to raise some Deleuzian considerations on Spinozist ontology to articulate the influence Deleuze has on the manner in which multinaturalist anthropology dialogues with indigenous mythologies and cosmologies. At last, with the help of some descriptions of Yanomami cosmology, as articulated (...) by Davi Kopenawa and Bruce Albert in The Falling Sky and of provocations raised by authors such as Jean-Christophe Goddard and Fabián Ludueña, this article will investigate the problems of dreams, images and specters a possible way to elaborate a multinaturalist theory of expression.
