Many authors were interested in separating the esthetic, the ethical and the religious but it may have been, as far as Kierkegaard was concerned, of more importance for the single individual to have a way to decide when one was becoming dominant over the other two. Henrik Stangerup, (1937-1998) a Danish writer, wrote three books as a way to illustrate Kierkegaard's three stages of existence, 1981, "The Road to Lagoa Santa", which was about Kierkegaard's brother-in-law Peter Wilhelm Lund (the ethicist), 1985 "The Seducer: It Is Hard to Die in Dieppe", Peder Ludvig Moller was the esthetic in that novel, and in 1991 "Brother Jacob" which describes Søren Kierkegaard as a Franciscan friar.
