I see a very Proustian movement between these two novels: from a widespread doubt, an agonizing crisis caused by the dissolution of «identity» andcertainties, announcing the Apocalypse in Natural novel, towards melancholic but serene acceptance of this crisis, under the sign of empathy in The Physics of Sorrow. After the agonizing conclusion that «we are I» follows the answer: «I are». I am all of humanity. Proustian movement of painful quest that ends with luminous epiphanies and opens interesting ways for renewing our approach and looking anew at both postmodern literature and «self-writings”. Which kind of writing could reflect the doubt, which is «inherently linked to métissage”, the mobility, the lability of “identity” today, if not postmodern, a Métis writing par excellence?
