Abstract
This research aims to examine the concept of haecceity conceived by Gilles Deleuze and Félix Guattari - which has started from the notion given to the concept in A Thousand Plateaus - Capitalism and Schizophrenia 2 (Mille Plateau: capitalisme et schizophrénie 2, 1980). To illustrate this concept the philosophers turned to literature, and more specifically the Proustian literature. They affirm that the haecceity concept has found in the episode with the small group (la petite bande) of girls in the seaside town of Balbec - the novel by Marcel Proust, In Search of Lost Time (À la recherche du temps perdu, 1913-1927) ¬- its best translation: "What's a girl, what is a group of girls? Proust at least show us and for all that their individuation, collective or singular, proceeds not by subjectivity but by haecceity, pure haecceity" (A Thousand Plateaus - Capitalism and Schizophrenia 2. Translation and foreword by Brian Massumi, Minnesota Press, 1987: 271). According to the Deleuzian thought, the fundamental question of haecceity concept is concentrated in its own definition: an individuation devoid of subjectivity, foreshadowing an individual who doesn't belong to individuation anymore, but it does to singularization. This non-subjectivated affirmation is part of an innovative philosophical proposal which has its own conceptual vocabulary: haecceity will exist in a new space (not extensive), where there's no distinction between the beginning or the end; the middle is where haecceity (formed by lines and not by points) will present itself as a rhizome. This mode of impersonal individuation reveals itself as a cartography that is made by forces - longitude - and intensities - latitude. Taking the group of girls as such a composition of forces moving, we will extract Albertine Simonet from it. She has the synonym of a group, and being adopted as an intercessor, she will leave the "group by group". The trajectory of this poetic and psychosocial entity (where the concept of haecceity originates from), will support us in the examination of the mode of existence of haecceity.
