Pierre-Félix Guattari (French pronunciation: [ɡwataʁi] audio speaker icon(listen); 30 March 1930 – 29 August 1992) was a French psychiatrist (psychiatrist), philosopher, semiologist and political activist. He is widely remembered for originating the concepts of schizoanalysis and ecosophy and for his influential collaborations with Gilles Deleuze, most notably the two-volume work collected under the title Capitalism and Schizophrenia. The first volume, Anti-Oedipus, appeared in 1972; the second, A Thousand Plateaus, followed in 1980.

Life and work

Born in 1930, Guattari trained and practised in psychiatry while also engaging in theoretical and political activities. He was associated with the psychiatric clinic at La Borde, where experimental and collective approaches to care shaped much of his thinking. Throughout his career he combined clinical practice with writing, teaching, and activism—participating in left-wing movements and environmental initiatives.

Key ideas

  • Schizoanalysis: proposed as an alternative to classical psychoanalysis, this approach emphasises social, economic and institutional forces in the formation of subjectivity rather than concentrating solely on familial or intra-psychic factors.
  • Ecosophy: Guattari used this term to describe a holistic political and philosophical stance that links environmental concerns with social and mental ecology, arguing that ecological issues must be addressed across multiple, interdependent domains.
  • Collaboration with Deleuze: the books they produced together merged philosophical critique with clinical and political observations, influencing later work in post-structuralist theory, cultural studies and critical psychiatry.

Selected writings

  1. Anti-Oedipus (1972) — with Gilles Deleuze.
  2. A Thousand Plateaus (1980) — with Gilles Deleuze.

Guattari's work has been taken up across disciplines—philosophy, psychoanalysis, cultural studies, and environmental thought—and continues to be discussed and debated for its proposals to rethink subjectivity, institutions and ecology in interconnected terms. He died in 1992.
