In the second year of Deleuze's consideration of cinema and philosophy, he commences the year by explaining that whereas he usually changes topics from one year to the next, he feels compelled to continue with the current topic and, in fact, to undertake a process of "philosophy in the manner of cows, rumination... I want entirely and truly to repeat myself, to start over by repeating myself." Hence, the 82-83 Seminar consists in once again taking up Bergson's theses on perception, but now with greater emphasis on the aspects of classification of images and signs drawn from C.S. Peirce. This allows Deleuze to continue the shift from considering the movement-image, that dominated early 20th century cinema, toward a greater understanding of the post-World War II emphasis on the time-image.
