Step-by-step explanation:
The quotation from Ralph Waldo Emerson's "Self-Reliance" best illustrates the tenet of Individualism. Emerson encourages the reader to think independently and resist the societal push towards conformity that diminishes a person's individual strengths and beliefs. He champions the idea that individuals should be self-reliant, trusting their own instincts and ideas rather than adhering to mass conformity. The concern for personal authenticity and distrust of societal norms is very much reflective of transcendentalist values, emphasizing the dignity and worth of the individual.
