Sentence:  “No sólo ser otro sino escribir la obra de otro” [“Not Only Being Other but Also Writing the Work of the Other”] thus engages Pessoa's poem “Autopsicografia” — attributed to the <WSD>orthonym</WSD> “Fernando Pessoa” — in a way that draws from the larger imaginary of Pessoa's notion of "channeling oneself," since Pessoa's poem's title, as Darlene Sadlier suggests, is "derived from the Portuguese "psicografia" [and] refers to the occult practice of writing through the suggestion or action of a spirit medium." 
Meaning of the word marked with <WSD> tags:  The real name of a person who uses a pseudonym.
