Definition of existential

The word "existential" originates from the 18th-century German philosopher Johann Gottlieb Fichte, who used the term "existentiell" to describe the relationship between existence and human consciousness. The term gained popularity in the mid-20th century, particularly among French philosophers such as Jean-Paul Sartre and Martin Heidegger. Sartre's philosophy, in particular, emphasized the idea of "existence precedes essence," which posits that humans are responsible for creating their own purpose and meaning in life, rather than being defined by a predetermined essence. This concept is often referred to as "existentialism." The term "existential" eventually crossed linguistic and cultural boundaries, becoming a mainstream concept in philosophy, psychology, and popular culture. Today, it is used to describe not only philosophical theories but also everyday experiences and emotions, such as the awareness of one's mortal existence, the search for purpose, and the uncertainty of the future.
