Mulla Sadra's metaphysics gives priority to existence over essence (i.e., quiddity). Scholastic logicians translated this into Latin as "quiddity" ("quidditas"). Only one of the beings from Quiddity remains, a creature named Noah. His fifth book of poems was "Two Odes of Quiddity and Nil". It is used in this sense in British poet George Herbert's poem, "Quiddity". Due to the close proximity to Quiddity, Raul's spirit departs Tesla's body. In Quiddity, Phoebe returns to Maeve's home. Tesla, Grillo and Jaffe flee the house and attempt to close the vortex into Quiddity. Noah convinces Joe to bring him through into Quiddity and promises him power. Joe's spirit departs his body and witnesses the Iad now heading across Quiddity. This is quiddity or "whatness" (i.e., its "what it is"). Tesla and Phoebe split up as Phoebe heads through the neirica into Quiddity. This quiddity cannot be demonstrated, but must be fixed by a definition.
