“Traces thus produce the space of their inscription only by acceding to the period of their erasure. From the beginning, in the present of their first impression, they are constituted by the double force of repetition and erasure, legibility and illegibility. A two-handed machine, a multiplicity of agencies or origins—is this not the original relation to the other and the original temporality of writing, its primary complication: an originary spacing, deferring, and erasure of the simple origin, and polemics on the very threshold of what we persist in calling perception? The stage of dreams was a stage of writing. But this is because ‘perception,’ the first relation of life to its other, the origin of life, had always already prepared representation. We must be several in order to write, and even to ‘perceive.’”
Jacques Derrida, “Freud and the Scene of Writing” in Writing and Difference.
Best reading of Freud; best critique of phenomenology.
