In George Eliot's "Daniel Deronda," the quote suggests that a lack of empathy leads to ignorance. The author implies that without understanding and caring for others, individuals diminish their own intelligence and insight. This connection emphasizes the importance of sympathy in fostering a well-rounded perspective on life. When we fail to engage with the feelings and experiences of others, we restrict our own understanding of the world.

The idea reflects a broader theme in Eliot's work, where human relationships and emotional connections play a crucial role in personal growth and enlightenment. True wisdom and understanding are often derived from our interactions with others, making empathy a vital component of intellectual and moral development. Thus, sympathy nurtures not just our social lives but also our cognitive abilities, highlighting the reciprocal relationship between compassion and insight.
