No references found | The term limen, meaning threshold in Latin, permeates various parts of the poem, although it does not herald an altogether new experience in all cases of its usage. Liminal--a term derived from the word limen, meaning threshold--is a psychological term denoting the threshold between the sensate and subliminal, a term that has entered postcolonial theory to locate an interstitial space between fixed identifications where difference, or cultural hybridity, or transgressive acts, may open new worlds of possibility, new narratives by which to live. The fictitious characters cross the line into the "real" world (Charlot, Tom Baxter, the young lady), the "real" characters enter the fictitious one (the censor, Cecilia), some fictional characters wind up in another fiction (Baxter in Juztrenka), and in all cases the passage of the limen into the other world is confirmed by the sense of touch. |
