Ralph Waldo Emerson in the context of "Walden"

Friedrich Wilhelm Nietzsche (15 October 1844 – 25 August 1900) was a German philosopher. He began his career as a classical philologist, turning to philosophy early in his academic career. In 1869, aged 24, Nietzsche became the youngest professor to hold the Chair of Classical Philology at the University of Basel. Plagued by health problems for most of his life, he resigned from the university in 1879, and in the following decade he completed much of his core writing. In 1889, aged 44, he suffered a collapse and thereafter a complete loss of his mental faculties, with paralysis and vascular dementia, living his remaining 11 years under the care of his family until his death. His works and his philosophy have fostered not only extensive scholarship but also much popular interest.

Nietzsche's work encompasses philosophical polemics, poetry, cultural criticism and fiction, while displaying a fondness for aphorisms and irony. Prominent elements of his philosophy include his radical critique of truth in favour of perspectivism; a genealogical critique of religion and Christian morality and a related theory of master–slave morality; the aesthetic affirmation of life in response to both the "death of God" and the profound crisis of nihilism; the notion of Apollonian and Dionysian forces; and a characterisation of the human subject as the expression of competing wills, collectively understood as the will to power. He also developed influential concepts such as the Übermensch and his doctrine of eternal return. In his later work he became increasingly preoccupied with the creative powers of the individual to overcome cultural and moral mores in pursuit of new values and aesthetic health. His body of work touched a wide range of topics, including art, philology, history, music, religion, tragedy, culture and science, and drew inspiration from Hebrew literature, Indian literature and Greek tragedy, as well as figures such as Zoroaster, Arthur Schopenhauer, Ralph Waldo Emerson, Richard Wagner, Fyodor Dostoevsky and Johann Wolfgang von Goethe.

American literature is literature written or produced in the United States of America and in the British colonies that preceded it. The American literary tradition is part of the broader tradition of English-language literature, but also includes literature produced in languages other than English.

The American Revolutionary Period (1775–1783) is notable for the political writings of Benjamin Franklin, Alexander Hamilton, Thomas Paine, and Thomas Jefferson. An early novel is William Hill Brown's The Power of Sympathy, published in 1791. The writer and critic John Neal in the early-to-mid-19th century helped to advance America toward a unique literature and culture, by criticizing his predecessors, such as Washington Irving, for imitating their British counterparts and by influencing writers such as Edgar Allan Poe, who took American poetry and short fiction in new directions. Ralph Waldo Emerson pioneered the influential Transcendentalism movement; Henry David Thoreau, the author of Walden, was influenced by this movement. The conflict surrounding abolitionism inspired writers, like Harriet Beecher Stowe, and authors of slave narratives, such as Frederick Douglass. Nathaniel Hawthorne's The Scarlet Letter (1850) explored the dark aspects of human nature, as did Herman Melville's Moby-Dick (1851). Major American poets of the 19th century include Walt Whitman, Melville, and Emily Dickinson. Mark Twain was the first major American writer to be born in the West. Henry James achieved international recognition with novels like The Portrait of a Lady (1881).

The Atlantic is an American magazine and multi-platform publisher based in Washington, D.C. It features articles on politics, foreign affairs, business and the economy, culture and the arts, technology, and science.

It was founded in 1857 in Boston as The Atlantic Monthly, a literary and cultural magazine that published leading writers' commentary on education, the abolition of slavery, and other major political issues of that time. Its founders included Francis H. Underwood and prominent writers Ralph Waldo Emerson, Oliver Wendell Holmes Sr., Henry Wadsworth Longfellow, Harriet Beecher Stowe, and John Greenleaf Whittier. James Russell Lowell was its first editor. During the 19th and 20th centuries, the magazine also published the annual The Atlantic Monthly Almanac. The magazine was purchased in 1999 by businessman David G. Bradley, who fashioned it into a general editorial magazine primarily aimed at serious national readers and "thought leaders"; in 2017, he sold a majority interest in the publication to Laurene Powell Jobs's Emerson Collective.

American philosophy is the activity, corpus, and tradition of philosophers affiliated with the United States. The Internet Encyclopedia of Philosophy notes that while it lacks a "core of defining features, American Philosophy can nevertheless be seen as both reflecting and shaping collective American identity over the history of the nation". The philosophy of the Founding Fathers of the United States is largely seen as an extension of the European Enlightenment. A small number of philosophies are known as American in origin, namely pragmatism and transcendentalism, with their most prominent proponents being the philosophers William James and Ralph Waldo Emerson respectively.

Samuel Taylor Coleridge (/ˈkoʊ.lə.rɪdʒ/ KOH-lə-rij; 21 October 1772 – 25 July 1834) was an English poet, literary critic, philosopher, and theologian who was a founder of the Romantic Movement in England and a member of the Lake Poets with his friend William Wordsworth. He also shared volumes and collaborated with Charles Lamb, Robert Southey, and Charles Lloyd.

He wrote the poems The Rime of the Ancient Mariner and "Kubla Khan", as well as the major prose work Biographia Literaria. His critical works were highly influential, especially in relation to William Shakespeare, and he helped introduce German idealist philosophy to English-speaking cultures. Coleridge coined many familiar words and phrases, including "suspension of disbelief". He had a major influence on Ralph Waldo Emerson and American transcendentalism.Throughout his adult life, Coleridge had crippling bouts of anxiety and depression; it has been speculated that he had bipolar disorder, which had not been defined during his lifetime. He was physically unhealthy, which may have stemmed from a bout of rheumatic fever and other childhood illnesses. He was treated for these conditions with laudanum, which fostered a lifelong opium addiction.

"Self-Reliance" is an 1841 essay written by American transcendentalist philosopher Ralph Waldo Emerson. It contains the most thorough statement of one of his recurrent themes: the need for each person to avoid conformity and false consistency, and follow his or her own instincts and ideas. It is the source of one of his most famous quotations:

This essay is an analysis into the nature of the "aboriginal self on which a universal reliance may be grounded". Emerson emphasizes the importance of individualism and its effect on a person's satisfaction in life, explaining how life is "learning and forgetting and learning again".
