For an hour or more, I remained too stunned to think; and it was not until I began to think, that I began fully to know how wrecked I was, and how the ship in which I had sailed was gone to pieces. (39.97)
Here we see the connection between those ships that Pip used to watch on the marshes at home those many years ago and his current circumstances.

The ships became a metaphor for a life of money and privilege—but once he actually got on board, it promptly sank. What does he have on his horizon now to dream about?
