In 1834, Emerson, formerly a Unitarian minister, began a new career as a public lecturer. Many of these lectures formed the source material for his essays. Nature (1836), his first published work, contained the essence of his transcendental philosophy, which views the world of natural phenomena as a sort of symbol of the inner life and emphasizes individual freedom and self-reliance. Essays of Ralph Waldo Emerson is a collection of twelve of his most celebrated and memorable essays from this period.
