For the philosopher Gilles Deleuze, rational Cartesian consciousness as the sole constituent of thought is insufficient because what is yet "unthought" is equally capable of producing practical effects at the level of human experiences. Deleuze considers "an unconscious of thought [to be] just as profound as the unknown of the body" (Deleuze, 1988a, p. 19; italics Deleuze's). The quality of profundity is significant and relates Deleuze's particular mode of production of human subjectivity, that he together with social psychologist Felix Guattari called 'schizoanalysis", to Jung's depth psychology. Kerslake (2007) notices that Deleuze's conception of the unconscious is closer to the Jungian rather than the Freudian. Jung's dynamic process of the individuation of the Self as the goal of analysis is akin to Deleuze's concept of becoming, and specifically becoming-other as a process of learning from the unconscious embedded in experience.
