Existentialism inspired Franklin Roosevelt and Martin Luther King Jr.

Existentialism is a loosely defined philosophy that encouraged authentic living

The writers and thinkers often characterized as “existentialist” sometimes contradict one another. Considering that, boiling the philosophy down to a set of tenets can be difficult. Generally, those associated with existentialism were inspired by the 19th-century works of Søren Kierkegaard and Friedrich Nietzsche, and they believed that individuals needed to defy conformity and define the meaning of life for themselves.

Many writers considered 'existentialist' didn't identify with the term

“Existentialism” was first introduced in 1943 by philosopher Gabriel Marcel. Jean-Paul Sartre and Simone de Beauvoir readily adopted the term, but others, such as Albert Camus and Martin Heidegger, rejected it. Earlier philosophers, like Søren Kierkegaard and Friedrich Nietzsche, were long dead by the time the word was in vogue.

Existentialism has been used as a therapeutic tool

Psychologists became interested in existentialism in the 1940s, with two Swiss psychiatrists—Ludwig Binswanger and Medard Boss—particularly taken with Martin Heidegger’s “Being and Time.” The existential approach to therapy emphasized a patient’s personhood and experiences, using them to help that patient face their problems head-on.

An existentialist reading list

If you’re looking for a starting point for diving into existentialist thought, this is a great resource. Its titles are not exactly obscure—Albert Camus’ “The Stranger,” Franz Kafka’s “The Trial,” and Søren Kierkegaard’s “Either/Or” are among the most famous works in Western literature—but the list provides some digestible context for each text, which will help you decide the best place to begin your journey.

Scholars trace existential anxiety back to early Hebrew scriptures

Novelist Richard Wright joined the existentialists in Paris

The author of “Black Boy” and “Native Son” left the United States in 1946 to escape his home country’s racial inequality. In Paris, he explored existentialist ideas and spent time with Simone de Beauvoir and Jean-Paul Sartre. “The Outsider,” a novel he wrote while living in France, embraced many of the philosophy’s central themes.

One teacher's lesson on existentialism and social media use

During a unit on existentialist literature and philosophy, one teacher at Massachusetts’ Phillips Academy asked students to surrender their cell phones to test Kierkegaard’s thoughts on the danger of conformity and Sartre’s belief that humans are “condemned to be free.” Many of them were surprised to find how liberated they felt once they left behind social media.

Sartre admired American novelist William Faulkner

In addition to writing philosophy and fiction, Jean-Paul Sartre was also a literary critic. His 1939 essay on Faulkner's "The Sound and the Fury" focused on the way the American novelist commented on time, favorably comparing him to Marcel Proust. Ultimately, Sartre argues Faulkner's "despair" about a "closed future" is a result of the "social conditions of our present life." Ever the existentialist, though, Sartre suggests this reality is something that should inspire rather than depress.

Kierkegaard used pseudonyms throughout his writing

“The Father of Existentialism” published over 40 texts and 40 articles during his life and used several pen names throughout them. The pseudonyms allowed him to present relevant opinions in a relatable, first-person manner without the reader believing that Søren Kierkegaard earnestly held them.
