"Textual Trees" thus spatially reorganizes poetic diction first by examining the length of individual words and then visualizing the possibilities of cybernetic algorithms that facilitate the partially aleatory re-writing of these literary texts. This material operation therefore decenters the univocality of meaning supposedly possessed by the "original" poetic word, henceforth destabilized by the new iteration of each poem. The complexity sphere in its Spanish "incarnation" includes 122 terms entered by Ortiz himself, selected for their use scientific as well as quotidian contexts. Ortiz theorizes about the language of "spheres"—in constant evolution, as function of the selection of terms and the links established between them—with respect to what he calls "linguistic phylogenetics." Structural linguistics—at least since Ferdinand de Saussure's Course on General Linguistics —is based on the notion of language as a system of differences without positive terms, conceived as a network of signs that establishes codependent relationships through which the stability of each individual sign is established.
