In Robert Jordan's "Winter's Heart," the character Lan reflects on the nature of knowledge and understanding. He acknowledges that it is impossible to possess complete knowledge, and that some of what we believe to be true may actually be incorrect. This recognition of our limitations is a significant aspect of wisdom, suggesting that humility is vital in our quest for truth.

Lan also emphasizes the importance of courage in the face of uncertainty. Despite acknowledging the flaws in our understanding, life requires us to continue moving forward. Thus, the ability to persist, knowing that our knowledge may be incomplete, illustrates both bravery and resilience in navigating the complexities of existence.
