Following publication of Anti-Oedipus in 1972, Deleuze continues to develop the proliferation of concepts that his collaboration with Guattari had yielded. Throughout the 1970s, Deleuze and Guattari's interest in expanding these concepts continues, eventually producing the sequel, A Thousand Plateaus.
Here we include the panel at IRCAM that Deleuze presented with Pierre Boulez, Roland Barthes and other artists and writers.
As for the 1977-78 seminar, only one recording has as yet surfaced, but the opening of the lecture indicates that Deleuze had devoted the entire year's seminar to the concept of "continuous variation," which appears frequently in A Thousand Plateaus. The lecture of 24 January 1978 is an exceptional example, as Deleuze notes, of his return to the history of philosophy by considering continuous variation in light of Spinoza's philosophy.
We have created this Seminar on "Continuous Variation" in the hope that recordings and/or transcripts on continuous variation and other topics will eventually become available to complete our documentary archive of the year-long teaching event.
The transcripts and translations -- at WebDeleuze as well as in the two volumes Deux régimes de fous and Two Regimes of Madness -- vary considerably from Deleuze's actual presentation in the IRCAM session. Hence our different versions in the second session.
