Sherlock Holmes expresses his disagreement with the notion that modesty is a virtue. He believes that true understanding requires viewing oneself and one’s abilities accurately and honestly. According to him, both underestimating oneself and overestimating one's capabilities are distortions of the truth.
This perspective highlights the importance of self-awareness and the need for individuals to assess their skills realistically. Holmes advocates for a logical approach to self-perception, suggesting that clarity in understanding one’s strengths and weaknesses is vital for making sound judgments.
