A knife sharpens a knife, and wisdom sharpens wisdom.
The quote "A knife sharpens a knife, and wisdom sharpens wisdom" suggests that growth and improvement often occur through interaction and collaboration. Just as two knives can hone each other's edges to become sharper and more effective, the exchange of knowledge and ideas among wise individuals enhances their understanding and insight. This highlights the importance of engaging with others in a pursuit of wisdom, implying that sharing experiences and learning from one another leads to greater depth and clarity of thought.
