The Semiotic Turn is a milestone in semiotics. Written by Paolo Fabbri (1939-2020) at the end of the millennium, it orients semioticians in their purpose to critically analyze different cultural and social worlds. Given the influence of Fabbri's thought on semioticians worldwide, this English translation introduces Fabbri’s work to English-speaking audiences. It includes previously unpublished texts by Fabbri and an introduction by the editor.
