Definitional issues and background[edit]
There has never been general agreement on the definition of existentialism. The technological term is often seen as a historical convenience as it was first applied to many philosophers in hindsight, long after they had died. In fact, while existentialism is generally considered to have originated with Kierkegaard, the first prominent existentialist philosopher to adopt the term as a self-description was Jean-Paul Sartre. Sartre purports the idea that that which "all existentialists have in common is the fundamental doctrine that existence precedes essence," as scholar F.C.

The Norwegian philosopher Erik Lundestad refers to the Danish philosopher Fredrik Christian Sibbern. Sibbern is supposed to have had two conversations in 1841, the first with Welhaven and the second with Kierkegaard. It is in the first conversation that it is believed that Welhaven came up with "a word that he said covered a certain thinking, which had a close and positive attitude to life, a relationship he described as existential".[16] This was then brought to Kierkegaard by Sibbern.
The second claim comes from the Norwegian historian Rune Slagstad, who claims to prove that Kierkegaard himself said the term "existential" was borrowed from the poet. He strongly believes that it was
