 The 1980s were a decade of independent works for Deleuze: Francis Bacon: Logic of Sensation (1981); Cinema I: The Movement-Image (1983); Cinema II: The Time-Image (1985); Foucault (1986); and The Fold: Leibniz and the Baroque (1988). He then resumed his collaboration with Guattari for their final joint work, What is Philosophy? (1991). His final years were spent in very ill health, although he did manage to publish a remarkable short essay, “Immanence: A Life” in 1995, before taking his own life on November 4, 1995.
