The quote "All rivers run to the sea, and the sea is not filled" from Hilary Mantel's "Wolf Hall" reflects the idea of endless ambition and the inexhaustible nature of desire. It suggests that just as rivers continuously flow towards the sea, people's aspirations and pursuits are continually pushed towards larger goals, but those goals, represented by the sea, are boundless and never completely satisfied. This indicates a profound commentary on the human condition, emphasizing the relentless quest for fulfillment.

This notion can be interpreted in the context of the characters within "Wolf Hall," as they navigate a world of political intrigue and personal ambitions. The characters' desires often drive them forward, yet they find that true satisfaction is elusive. The metaphor of the sea suggests that there are always new challenges and desires awaiting, reinforcing the idea that in life, just as in politics and power, there is no final destination. The journey is ongoing, and the pursuit of one's goals is an integral aspect of existence.
