Becoming-city explores the encounter between Self and Other in Hanoi, Vietnam, through Deleuze’s philosophy of difference. Theory, experience, history, literature, language, and data are combined in order to ask what it is that individuates subject and object. Deleuze’s philosophy of difference is used to explore and push problems of difference and identity to their limits through writing of the encounter between individual and city. This encounter is employed not as metaphor but as the actual process of movement through which events take place and thinking is engendered, leading to possibilities of thinking differently about difference.
