The Unconscious is Semiotic, not Linguistic explores the unconscious as a multiplicity—less a language than a field of signs, intensities, and micro-perceptions. In dialogue with thinkers such as Félix Guattari and Sándor Ferenczi, Lucas Ferraço Nassif revisits and challenges Lacanian psychoanalysis. The book itself becomes part of the experiment: multiple voices, temporalities, and layers of text create a reading experience where book, language, and reader form a single assemblage. This second edition features editorial revisions, a redesigned black-and-white layout, and an additional text by the editor.
