In "Treason's Harbour" by Patrick O'Brian, a character expresses deep regret for a past action. He acknowledges the remarkable abilities of another man who possesses fluency in multiple languages, particularly those spoken in the Levant, in addition to excellent English. This man's skills are so extraordinary that it's suggested he could have constructed the Tower of Babel by himself, highlighting his capability and resourcefulness.
The quote reflects on the wasted potential and talents of the individual in question. It emphasizes the sorrow of recognizing someone's exceptional qualities only after losing or failing to appreciate them adequately. The mention of the Tower of Babel serves as a metaphor for this man's vast capabilities, underscoring the themes of communication and misunderstanding that are prevalent throughout the narrative.
