In "The Memoirs of Sherlock Holmes," Arthur Conan Doyle emphasizes the importance of acknowledging danger when it is imminent. He argues that ignoring a threat is not an act of bravery, but rather a foolish denial of reality. This perspective highlights the need for awareness and the wisdom in facing uncomfortable truths rather than pretending they do not exist.

Doyle’s quote serves as a reminder that true courage involves facing fears and recognizing when danger is present. It prompts readers to reflect on how often they might overlook risks in their own lives, advocating for a proactive approach to threats instead of succumbing to ignorance.
