“The key to every man is his thought. Sturdy and defying though he look, he has a helm which he obeys, which is the idea after which all his facts are classified. He can only be reformed by showing him a new idea which commands his own.”

American essayist and poet of the 19th century, Emerson is best known for his transcendentalist philosophy and influential lectures on self-reliance and individualism. His works, including "Self-Reliance" and "Nature," championed intuition, personal experience, and the inherent goodness of humanity.
