在後現代論述中，主體迭經解構，許多解構學者或認為主體已死或不具深意。哲學家、藝術家、或理論學者轉而從「他者」來探究主體；換言之，他者成為探究主體的另一個視角。本篇論文以互文方式剖析詩人佛多里柯‧賈西亞‧羅卡之生命敘事；論文將羅卡的生平與其詩作《紐約詩人》互文對比，測繪主體或生命論述之「空」、「缺」、「異」、「抑」、「隱」、「晦」等「他者」面向。在拉康主體概念的視角下，羅卡之生命敘事是悼念遺失「物」或「他者」之輓歌，也是無法企及之欲求的一種轉喻（metonymy）。

The concept of subject has been critically revised by the theoreticians throughout humanistic fields; post-structuralists, for instance, reflect the continuing confusion by looking upon the subject as either dead or of little significance. Such demise makes the postmodern philosophers, artists, or theoreticians turn to the “other” to get an access to the subject. The move to the negation becomes the way to find the absent or obscure meaning and definition for the subject targeted. Paradoxically, the other has thus become an issue of considerable importance to study subjectivity. This essay intends to map the other as the core of subjectivity through an intertextual study of the life narrative of Federico García Lorca as a living person and as a poetic subject in Poet in New York. It reveals that Lorca’s life narrative, if viewed in light of Lacanian concept, is an elegy for the lost thing or other and a metonymy for the unattainable desire.
