"Christian Metaphysics and Neoplatonism" (1936) is the title of Albert Camus' thesis that would obtain for him permission to teach in the secondary schools of France.
Camus uses Augustine of Hippo and Pelagius to elaborate his moral views in regard to Greek thought and Christianity.
[1][2] Although it has never been published separately, this text was included in his collected works from the fr:Bibliothèque de la Pléiade.
Camus wrote his thesis in order to complete his studies at the University of Algiers.
As is required for such a dissertation, Camus not only had recourse to primary sources namely, Plotinus and Augustine, but he also studied and used studies of recent French authors, notably Émile Bréhier, Franz Cumont, Étienne Gilson, René Arnou, Pierre de Labriolle and Aimé Puech.
