This essay analyses works by Rui Torres and Luís Serguilha as proliferative and de-referentialized expressions of language towards a horizon devoid of self. The factorial permutations that occur in both works — with or without computer assistance — allow us to imagine a literary art whose combinatorial flow, like the passage of time, resides in the pure potentiality and fictionality of its unrepeatability. The reification of language contained in the poetics of expressive singularity, which has so far dominated our practices and concepts of literature, gives rise to an attention to the infinite modulations of the act of saying as an opening to the flow of its becoming, freed from an origin and from a destination.
