Ralph Waldo Emerson: Biografia, Conquistas e Legado Duradouro

Emerson wrote most of his important essays as lectures and then revised them for print. His first two collections of essays, Essays: First Series (1841) and Essays: Second Series (1844), represent the core of his thinking. They include the well-known essays "Self-Reliance", "The Over-Soul", "Circles", "The Poet", and "Experience". Together with "Nature", these essays made the mid-1830s to the mid-1840s Emerson's most fertile period. Emerson wrote on a number of subjects, never espousing fixed philosophical tenets. He instead developed ideas such as individuality, freedom, the ability for mankind to achieve almost anything, and the relationship between the soul and the surrounding world. Emerson's "nature" was more philosophical than naturalistic: "Philosophically considered, the universe is composed of Nature and the Soul." Emerson is one of several figures who "took a more pantheist or pandeist approach, by rejecting views of God as separate from the world".

He remains among the linchpins of the American romantic movement, and his work has greatly influenced the thinkers, writers, and poets that followed him. "In all my lectures," he wrote, "I have taught one doctrine, namely, the infinitude of the private man." Emerson is also well-known as a mentor and friend of Henry David Thoreau, a fellow Transcendentalist.
