Has there been a shift in our concept of immateriality? In Immaterialism , Vilém Flusser explores some of the signs that point towards a cultural shift in relation to what we regard as immaterial. A shift which he considers fundamental for the understanding of the wider cultural changes we experience today. First published in Portuguese, as an essay in 1987 in the Boletim da Sociedade Brasileira de História da Ciência, it was subsequently translated by the author into German and English. This edition presents Flusser's own English version of the text set as a visual poem by the artist Chagrin. This book is the first title of the Metatext series by Metaflux, edited by Rodrigo Maltez Novaes.
