Summary
This quote implies that, similar to how a person's desire for money increases with each sum they acquire, the thirst for knowledge grows as one acquires more knowledge. The more someone learns and discovers, the more they become aware of the vast depths of knowledge yet to be explored. It suggests that knowledge is an insatiable pursuit, as the more one knows, the more they realize how much there is still to learn, fueling their desire to seek further knowledge and understanding.
