The series success attracted the attention the Nouvelle Revue française, where he was invited to join the staff as an Editor, a position he remained in for many years.
His interest in avant-garde literature and art and its most modern and provocative expressions during the interwar period, was the impetus behind the creation, together with Antonin Artaud and Roger Vitrac, of the Théâtre Alfred Jarry.
Those works constituted the principal theoretical base on which he created the group Ordre Nouveau (The New Order) in 1929, and its literary magazine Esprit represented one of the most original expressions of the Nonconformist Movement during the 1930s.
In 1940, the advent of World War II interrupted his editorial work at the Nouvelle Revue Française, a literary magazine.
After being released, he was not allowed to travel to Paris and instead moved to Lyon, where he became involved, through his friend Jean Rigaut, in preparations for the American embarkments in North Africa.
Soon after he was able to escape to Algiers, thanks to Jean Jardin, a former contributor to l'Ordre Nouveau, and at the time director of Pierre Laval's cabinet.
Aron took up editorial duties again after the Liberation of France, most notably at the publishing houses Librairie Académique Perrin and later, Éditions Fayard.
His book "The God of the Beginnings" (New York: Morrow, 1966) explores the origins of religion and its development in the traditions of the Old Testament (e.g., Abraham, Moses, the Sinai Covenant).
In 1974, he was elected a member of the Académie française (number 650) but he died suddenly of a heart attack on 19 April 1975, before he was able to attend his public acceptance ceremony.
