In this chapter of Bronte's Wuthering Heights, Edgar is gazing out toward Gimmerton Kirk as he states (somewhat introspectively) that Cathy is living hope at his side.  When Bronte uses the term that he is "half solioquized" this speech, we get a further idea of his self-contemplation.  Reading the lines that immediately follow "Cathy as living hope" we see the obvious contrast with death and morbidity--an ending. Cathy as the living hope is exactly what it says- hopes are alive with Cathy beside Edgar.  But death or some type of finale looms- evident as Edgar ponders the grave-  "lying through the long June evenings on the green mound of her mother's grave, and wishing, yearning for the time when I might lie beneath it."  The final line in the paragraph makes Edgar's meaning more obvious.  The contrast and meaning is the difference in beginnings and endings, life and death.
