In the book "Middlemarch" by George Eliot, the character Caleb emphasizes the idea that one should not let the opinions of ignorant people prevent them from pursuing worthy actions. He believes that internal conviction and self-assurance in one's plans are crucial for success, and distractions from foolish judgments can lead to hesitance and failure.

Caleb's passion for this principle is evident as he gestures emphatically, underlining that regardless of external criticism, a clear and resolute plan is essential. It is a reminder that confidence in one's own decisions and actions is vital to accomplishing meaningful work, despite societal pressures.
