The quote "Let him think that I am more man than I am and I will be so" from Ernest Hemingway's novel "The Old Man and the Sea" reflects the theme of self-perception versus external expectation. The protagonist, Santiago, grapples with his identity as a fisherman, feeling the weight of his age and limitations. This line suggests that the way others perceive him influences his self-concept, motivating him to rise above his current reality and embody the qualities others admire in him.

This idea resonates throughout the narrative as Santiago faces immense challenges during his struggle with the marlin. By aligning his identity with the expectations of strength and resilience, he taps into a deeper well of courage and determination. Hemingway encapsulates the notion that one's sense of self can be shaped by the beliefs and expectations of others, ultimately leading to personal transformation in the face of adversity.
